EUROPE’S TAX PARADOX: WHO ACTUALLY PAYS?

There is a fundamentally misleading way to discuss taxation in Europe.

We look at statutory tax rates.

We compare Italy with Germany, France with Spain, Denmark with Bulgaria.

We say that one country taxes people at 43%, another at 45%, another above 50%, and another at only 10%.

Then we announce that one country is “high tax” and another is “low tax”.

That comparison tells us surprisingly little about how people actually live.

The real fiscal equation is far more important:

What do you earn?

How much of your labour cost disappears in taxes and social contributions?

How much do you actually take home?

What can that money buy where you live?

What public services do you receive in exchange?

And finally — the uncomfortable question that European governments often prefer to discuss separately:

Does everyone else actually pay what they are supposed to pay?

Because if they do not, taxation stops being merely a question of rates.

It becomes a question of redistribution between taxpayers themselves.

Not redistribution from rich to poor.

But redistribution from the traceable to the untraceable.

From those whose income is known automatically by the tax authority to those whose real income depends partly on what they choose to declare.

That is the hidden tax divide of Europe.

1. THE FIRST NUMBER PEOPLE GET WRONG: THE TOP TAX RATE

A marginal tax rate is not the percentage of your entire income that goes to the government.

Europe mostly uses progressive personal income taxation.

Take Italy.

The current national IRPEF structure essentially applies progressively:

23% on the first income band;

33% on the next band;

43% on income above the highest threshold.

A person reaching the 43% bracket does not pay 43% on every euro earned.

Only the portion of taxable income falling into that bracket is taxed at 43%.

France operates a broader progressive ladder, moving from a zero-rated band through 11%, 30%, 41% and ultimately 45%.

Germany applies a tax-free allowance followed by continuously increasing progressive rates, eventually reaching 42% and 45% for very high incomes.

Spain combines national and regional taxation. Consequently, the final marginal rate varies substantially according to the autonomous community.

The United Kingdom — no longer an EU member but extremely useful as a European benchmark — has its own allowance and bands, with the main system in England, Wales and Northern Ireland moving from 20% to 40% and ultimately 45%.

But none of these headline figures tells us what the average worker actually loses.

For that, there is a better measure.

2. THE NUMBER THAT MATTERS MORE: THE TAX WEDGE

The OECD calculates the tax wedge.

It measures the difference between what employing a worker costs and what that worker ultimately receives, taking into account personal income taxes and employee and employer social contributions.

For a single worker without children earning the national average wage, the 2025 figures were striking:

Belgium: 52.5%

Germany: 49.3%

France: 47.2%

Austria: 47.1%

Italy: 45.8%

Finland: 42.5%

Spain: 41.4%

Sweden: 41.1%

Denmark: 35.8%

United Kingdom: 32.4%

The OECD average was 35.1%. (OECD⁠)

This immediately destroys one popular misconception.

Denmark is famous as a high-tax country.

Yet measured through the OECD tax wedge on an average single worker, Denmark is below Germany, France, Italy, Finland, Spain and Sweden.

Why?

Because “high taxation” can be constructed in very different ways: personal income taxes, employer contributions, employee contributions, consumption taxes and other levies interact differently across national systems.

So comparing top income tax rates alone is nearly meaningless.

3. NOW ADD SALARIES — AND THE PICTURE CHANGES AGAIN

Suppose two workers both surrender around 40% of the economic value generated by their employment to taxes and social contributions.

That does not mean they enjoy the same living standard.

If one earns €30,000 and the other €60,000, the same percentage produces a very different outcome.

And even the net figure is not enough.

A net income of €35,000 in one European capital may buy far less housing, transport or services than the same nominal amount somewhere else.

That is why serious comparisons must follow four steps:

Gross labour income → taxes and contributions → net disposable income → purchasing power.

Purchasing-power adjustments answer a simple question:

How much real consumption can that income finance where the person actually lives?

This is the comparison politicians should be making.

Not simply:

“Your tax rate is 40%.”

But:

“You start with this income, you lose this amount to the fiscal system, you retain this amount, and after adjusting for local prices your disposable income has this real value.”

That is what determines living standards.

4. LOW TAX DOES NOT AUTOMATICALLY MEAN HIGHER PROSPERITY

Consider the low-tax systems in parts of Central and Eastern Europe.

Bulgaria has historically operated a 10% flat personal income tax.

Romania has also relied on relatively low headline personal income taxation.

These rates look extraordinarily attractive beside the maximum rates found in France, Denmark, Belgium or Austria.

But there is an obvious problem.

Ten percent of a much smaller salary can leave a household poorer than forty percent of a much larger salary.

Taxation cannot be separated from productivity.

Productivity cannot be separated from wages.

And wages cannot be separated from prices.

A low-tax country with low wages may still leave its citizens with considerably less purchasing power than a high-tax country with very high wages.

This is why the slogan “lower taxes equal richer citizens” is economically incomplete.

Sometimes they do.

Sometimes they do not.

5. THE NORDIC CASE: YES, TAXES ARE HIGH. BUT LOOK AT WHAT TAXPAYERS BUY

This is where the European debate becomes especially interesting.

Denmark, Sweden and Finland have historically accepted relatively high levels of taxation.

But taxation cannot rationally be evaluated without examining what taxpayers receive in return.

Healthcare.

Education.

Childcare.

Public administration.

Digital government.

Infrastructure.

Social insurance.

Unemployment protection.

Parental support.

Public safety.

Institutional reliability.

Administrative simplicity.

OECD evidence helps explain why taxation in these countries cannot simply be compared with taxation elsewhere by looking at rates.

In Finland, 83% of people who had recently used public administrative services reported satisfaction with those services, compared with an OECD average of 66%.

In Denmark the equivalent figure was 72%.

Denmark also maintained satisfaction with its education system above 74% in the OECD comparison.

Finland’s trust in national government was 47% versus 39% across the OECD comparison, while Denmark was also above the OECD average. (OECD⁠)

The European Commission describes Denmark as benefiting from high-quality public services, robust digital infrastructure and leadership in digital inclusion, trust and security. (Digital Strategy⁠)

This matters enormously.

A high-tax system that finances accessible childcare, functional digital administration, high-quality education, healthcare, social protection and reliable institutions is economically and politically different from a high-tax system where citizens must then privately purchase substitutes for poorly functioning public services.

Imagine two families each paying €30,000 a year in direct and indirect taxes.

Family A receives excellent public education, functioning healthcare, efficient childcare, digital administration and reliable public transportation.

Family B pays the same €30,000 but must additionally purchase private healthcare, private education, private childcare and private transport because public alternatives are inadequate.

The headline tax burden may be identical.

The effective economic burden is not.

That distinction is crucial.

6. TAXES SHOULD BE JUDGED LIKE A PRICE

There is a remarkably simple way of thinking about taxation.

A tax is partly the price citizens pay for collective goods.

Nobody evaluates the price of a product without asking what the product contains.

Yet political debate routinely evaluates taxation exactly that way.

“Denmark pays a lot of tax.”

True.

But what does Denmark receive?

“Finland has substantial taxation.”

True.

What public services does a Finnish household therefore not have to purchase privately?

This does not mean Nordic governments are perfect.

They are not.

Nor does it mean every additional euro of public spending produces value.

It means that a comparison of taxation without a comparison of public-sector output is intellectually incomplete.

The real question is not merely how much government takes. It is how much value government returns.

7. THEN COMES THE MUCH UGLIER PROBLEM: TAX EVASION

Now suppose the fiscal system is expensive but broadly universal.

Everyone contributes.

The burden may be high, but the contract is reasonably clear.

Now change the scenario.

One citizen earns €50,000 as a salaried employee.

His employer reports the income.

Taxes are withheld.

Social-security contributions are transmitted.

The tax authority already knows almost everything before the employee files a return.

Another citizen economically earns €50,000 through an activity involving self-declared revenues, cash payments or transactions that are more difficult for third parties to verify.

He declares €35,000.

Both people drive on the same roads.

Their children may attend the same schools.

They use the same hospitals.

They call the same police.

They rely on the same judiciary.

They receive the protection of the same state.

But one finances the system on €50,000 of income.

The other finances it on €35,000.

Who pays the difference?

Ultimately:

everyone who remains compliant.

8. THIS IS THE REAL TAX ON HONESTY

Governments do not have a magical independent source of money.

Over time, missing tax revenue has to appear somewhere else.

It can produce:

higher taxes on compliant taxpayers;

lower public services;

larger deficits;

higher public debt;

or some combination of all four.

Tax evasion therefore does not abolish taxation.

It redistributes taxation.

That is one of the most important economic facts missing from public discussion.

When someone hides €10,000 of taxable income, the tax connected to that income does not disappear from society’s financing requirements.

Someone else eventually carries the cost.

This can happen indirectly and over many years, but the arithmetic remains.

9. ITALY: THE MOST UNCOMFORTABLE NUMBER IN THE DEBATE

Italy offers perhaps the clearest example.

Official Italian estimates of the personal income-tax gap associated with business and self-employed income have remained around an extraordinary level: roughly 60% of the theoretical liability in recent estimates.

This must be interpreted correctly.

It does not mean that 60% of self-employed Italians are tax evaders.

It does not mean that every taxi driver, hairdresser, restaurant owner or professional hides income.

It means that the difference between theoretical and collected personal income tax in this segment is extraordinarily large.

That is a completely different statement — and an economically devastating one.

By contrast, salaried employment is subject to extensive third-party reporting and withholding.

The asymmetry is obvious.

The employee cannot normally decide that €45,000 of salary should become €27,000 when reported to the tax authority.

The number already exists elsewhere.

That is why the most important dividing line in modern taxation is sometimes not:

rich versus poor.

It is:

third-party reported income versus self-reported income.

10. TAXI DRIVERS, HAIRDRESSERS, RESTAURANTS AND PROFESSIONALS: THE PROBLEM IS NOT THE PROFESSION

This subject requires precision because it is easy to turn economic analysis into caricature.

A taxi driver is not an evader because he is a taxi driver.

A hairdresser is not an evader because she is a hairdresser.

A restaurant owner is not an evader because he owns a restaurant.

Millions of self-employed people report their income correctly.

The structural problem is different.

Whenever the tax authority lacks an independent record of the transaction, the taxpayer has more room to under-report it.

Cash-heavy businesses historically created precisely this problem.

This is why electronic invoicing, electronic payments, third-party reporting and digital cash registers matter.

They do something incredibly simple:

they transform one person’s declaration into a transaction observed by two or more parties.

And compliance tends to rise.

11. BRITAIN CONFIRMS THE SAME PATTERN

This is not an Italian cultural curiosity.

HM Revenue & Customs publishes unusually detailed tax-gap estimates.

For the UK Self Assessment business population — mainly self-employed taxpayers and small partnerships — the estimated tax gap for 2024-25 was 29.2% of theoretical liability, equivalent to approximately £9.8 billion. (GOV.UK⁠)

The important point is not simply the £9.8 billion.

It is the difference between income taxed through tightly reported systems and income that relies much more heavily on self-assessment.

The same economic mechanism appears again.

Where tax authorities have reliable independent information, compliance is generally much higher.

Where the taxpayer controls more of the information, the gap becomes larger.

12. AND BRITAIN SHOWS SOMETHING EVEN MORE WORRYING

The UK Self Assessment business tax gap was estimated at 20.7% of theoretical liability in 2005-06.

It fell to 18.7% in 2017-18.

It has subsequently climbed back to around 29%, reaching the estimated 29.2% in 2024-25. (GOV.UK⁠)

So technological sophistication does not automatically eliminate tax non-compliance.

Rules matter.

Enforcement matters.

Reporting systems matter.

Administrative capacity matters.

Tax morale matters.

And perhaps most importantly:

the probability of detection matters.

A theoretical penalty is irrelevant when the perceived probability of ever paying it is close to zero.

13. THE EMPLOYEE DOES NOT HAVE THE SAME CHOICE

This deserves to be stated plainly.

In ordinary regular employment, income-tax evasion on the salary itself is extremely difficult because the payer is known.

The employer records the salary.

Banks record payments.

Social-security systems record contributions.

Tax administrations receive information.

The worker’s capacity to erase part of the salary is minimal.

That makes employees one of the easiest groups in society to tax.

Governments know it.

And governments behave accordingly.

This creates a disturbing political economy.

When a state needs another billion euros quickly, increasing a tax on a fully traceable base is easier than finding a billion euros hidden across hundreds of thousands of small undeclared transactions.

The compliant taxpayer therefore risks being taxed not because he is necessarily richer.

But because he is easier to find.

14. THE SHADOW ECONOMY CREATES TWO CITIZENSHIPS

Undeclared work takes the problem further.

An individual may work partly off the books.

An employer may under-report hours.

Cash wages may not appear in official accounts.

A service may be performed without an invoice.

A rental payment may remain outside the declared economy.

The consequences are broader than lost personal income tax.

They can include lost:

social contributions;

VAT;

local taxes;

business taxes;

and other associated revenues.

Yet the person operating partly outside the tax system does not simultaneously disappear from the state.

He remains a citizen.

He remains eligible for public infrastructure and, subject to the relevant rules, public services and social protections.

This produces the fundamental free-rider problem.

Someone can contribute less to a collective good while continuing to consume it.

And that is economically equivalent to transferring part of the cost to everyone else.

15. WE MUST SEPARATE PERSONAL TAX EVASION FROM CORPORATE AND VAT EVASION

This article is specifically about individuals.

So corporate income-tax evasion and VAT gaps should not be mixed mechanically with personal income-tax evasion.

But they cannot be completely ignored.

Why?

Because the state has one balance sheet.

If governments lose billions through VAT fraud, undeclared commercial activity or corporate tax non-compliance, those missing resources affect the same fiscal system financing healthcare, pensions, education and debt service.

A government facing persistent revenue leakage has three basic options:

recover it;

reduce spending;

or raise resources elsewhere.

And “elsewhere” very often means the easiest tax bases to observe.

Labour.

Consumption.

Property.

Fuel.

And compliant income.

So corporate and VAT evasion indirectly matter enormously to individuals even when we exclude them from the personal-tax statistics.

16. THE FALSE MORAL ARGUMENT: “TAXES ARE TOO HIGH, THEREFORE EVASION IS UNDERSTANDABLE”

High taxation can certainly increase incentives to avoid or evade tax.

Economists have studied that relationship for decades.

But the argument is incomplete because causality operates in both directions.

High taxes can encourage evasion.

And high evasion can force higher taxes.

Imagine the state requires 100 units of revenue to finance a given level of services.

If the theoretical tax base is 1,000, it needs an average effective collection rate of 10%.

But if 200 units of that base disappear into the shadow economy and the government can reliably tax only 800, obtaining the same 100 requires a 12.5% rate on the remaining observable base.

The compliant taxpayer is now paying 25% more relative to the original rate because part of the tax base disappeared.

This simplified example captures the mechanism better than a thousand political speeches.

Tax evasion can literally create higher tax rates for everyone left behind.

17. HOW MUCH LESS COULD WE PAY IF EVERYONE PAID?

This is where we need intellectual discipline.

It is impossible to say:

“Every Italian employee pays exactly €X because of tax evasion.”

Tax systems are not mechanically redistributed euro for euro.

Some recovered revenue would reduce deficits.

Some could increase expenditure.

Some might reduce taxes.

Behaviour would change.

Economic output might change.

Enforcement has costs.

A zero tax gap is unrealistic.

But a useful counterfactual is possible.

If a government raises €100 billion from a particular tax and the theoretical liability suggests it should raise €110 billion, eliminating the €10 billion gap could theoretically allow the same revenue to be collected with a roughly 9% lower burden on the amount currently being collected — if every euro recovered were returned through lower taxes.

That final condition matters.

The tax cut would not happen automatically.

It would be a political decision.

But the fiscal space is real.

That is the point.

Tax evasion destroys fiscal space.

18. ITALY’S PROBLEM IS PARTICULARLY PERVERSE

Italy combines several difficult characteristics.

A very high tax wedge on regular labour.

In 2025, the OECD put the tax wedge for an average single worker at 45.8% of labour costs. (OECD⁠)

Persistent wage weakness relative to several northern European economies.

A large public debt.

High demands on the welfare state.

And an exceptionally large estimated personal income-tax gap in segments of self-employed and business income.

This produces perhaps the worst possible combination:

high taxation for people who cannot avoid it and incomplete collection from parts of the economy where income is harder to observe.

That is not progressivity.

That is an information problem masquerading as a tax system.

19. GERMANY: VERY HIGH LABOUR TAXATION, BUT A DIFFERENT INCOME BASE

Germany had a 49.3% tax wedge on the average single worker in 2025 — considerably above Italy’s 45.8%. (OECD⁠)

So saying simply “Italians are more taxed than Germans” would be wrong under this measure.

But Germany starts from different levels of productivity, wages and household purchasing power.

This is why a tax-wedge ranking and a living-standard ranking are not the same thing.

A worker can face a larger percentage deduction and still retain more real purchasing power because his starting wage is substantially higher.

Again:

percentage taxation is only one side of the equation.

20. FRANCE: HUGE REDISTRIBUTION, HIGH TAXATION, HIGH PUBLIC SPENDING

France also has one of Europe’s largest labour tax wedges: 47.2% for the OECD average-worker case in 2025. (OECD⁠)

It operates one of Europe’s most extensive social models.

This makes the French debate different again.

The appropriate question is not merely whether French taxes are high.

They clearly are.

The relevant question is whether the combination of income, redistribution, healthcare, pensions, family benefits and public services justifies the economic burden and whether the system distributes that burden fairly.

That is a far more sophisticated debate than comparing France’s top marginal income-tax rate with another country’s.

21. SPAIN: LOWER LABOUR TAXATION THAN ITALY, FRANCE OR GERMANY — BUT LOWER STARTING INCOME

Spain’s 2025 average-worker tax wedge was 41.4%.

That is materially below Germany, France and Italy. (OECD⁠)

But again, the Spanish worker does not automatically have a higher standard of living.

Salary levels matter.

Unemployment and labour-market participation matter.

Regional differences matter.

Housing costs matter.

Purchasing power matters.

So a worker in Madrid paying a lower percentage of labour cost in taxes may still possess less real disposable purchasing power than a worker in Munich facing a higher tax wedge.

This is precisely why the comparison must proceed in sequence:

salary first, tax second, net income third, prices fourth, services fifth.

Anything else is incomplete.

22. DENMARK DESTROYS THE SIMPLE “HIGH TAX = BAD” FORMULA

Denmark is perhaps the most useful example.

It is conventionally described as one of the world’s highest-tax countries.

That is broadly understandable when the entire fiscal system is considered.

Yet the OECD tax wedge on an average single employee was 35.8% in 2025.

Italy: 45.8%.

France: 47.2%.

Germany: 49.3%. (OECD⁠)

And Denmark simultaneously combines substantial taxation with strong public services and high levels of satisfaction in several areas.

This is enormously important.

The problem is not necessarily paying a great deal of tax.

The problem is paying a great deal of tax and then feeling obliged to buy privately what you already financed publicly.

That is double taxation in the household’s economic reality, even when it is not legally called a tax.

23. THERE IS ALSO SOMETHING CALLED TAX MORALE

People are more willing to participate in a fiscal system when they believe three things:

that other people are also paying;

that the government uses the money reasonably well;

and that public institutions treat citizens fairly.

Break any one of these and compliance becomes harder.

Break all three and a fiscal system enters a vicious circle.

Citizens see others cheating.

They conclude that compliance is for fools.

The state responds with higher taxation on observable bases.

Compliant citizens become angrier.

Political support for taxation collapses.

More people search for ways around the system.

Enforcement becomes more aggressive.

Trust falls further.

The fiscal contract starts to disintegrate.

24. THE NORDIC LESSON IS NOT “RAISE TAXES”

The lesson from Scandinavia should not be caricatured.

It is not:

“Denmark has excellent services, therefore every country should raise taxes.”

The lesson is much more demanding.

If you ask citizens to surrender a large share of their economic income, the state must justify that price with institutional quality, universal compliance and visible public value.

High taxes plus poor enforcement are politically toxic.

High taxes plus inefficient services are economically damaging.

High taxes plus widespread evasion are morally corrosive.

High taxes plus good services, strong institutions and broad compliance can instead form a stable social contract.

That distinction is everything.

25. THE MOST DANGEROUS INEQUALITY MAY BE BETWEEN THOSE WHO CAN HIDE AND THOSE WHO CANNOT

European tax politics still speaks almost exclusively about income brackets.

Who earns €20,000?

Who earns €50,000?

Who earns €100,000?

Who should pay more?

But perhaps another axis matters almost as much.

Who receives income that is automatically visible?

Who receives income that is partly self-reported?

Who receives cash?

Who invoices electronically?

Who is subject to withholding?

Who can manipulate timing?

Who can shift income?

Who can simply fail to record a transaction?

This is an inequality of fiscal optionality.

Two people with exactly the same real income may face radically different effective taxation because one has no practical choice but to comply while the other possesses more room not to.

That is profoundly unfair.

26. THE SOLUTION IS NOT TO DEMONISE THE SELF-EMPLOYED

The solution is to make information symmetrical.

Electronic invoicing.

Electronic receipts.

Digital payments.

Third-party reporting.

Data matching.

Pre-filled tax returns.

Information exchange between banks and tax administrations under proper legal safeguards.

Risk-based audits.

Better cross-border cooperation.

Fewer loopholes.

Simpler tax codes.

Fewer amnesties.

Fast enforcement.

And, crucially:

lower rates when the tax base becomes broader.

Compliance should produce a dividend.

Otherwise citizens see only surveillance and no reward.

27. THE WORST POLICY IS A TAX AMNESTY FOR THE NON-COMPLIANT FOLLOWED BY HIGHER TAXES FOR THE COMPLIANT

Nothing destroys tax morale faster.

A citizen pays on time for twenty years.

Another delays, hides or under-reports.

Then government introduces a favourable settlement, reduced penalties or another extraordinary regularisation.

The honest taxpayer receives nothing.

The delinquent taxpayer receives a discount.

What lesson has the state just taught?

That compliance is not a virtue.

It is poor financial planning.

Repeated tax amnesties therefore have a cost that extends far beyond the revenue immediately forgiven.

They alter expectations about future enforcement.

28. WHO REALLY PAYS FOR TAX EVASION?

The answer is not “the government”.

It is:

the salaried employee whose withholding cannot be avoided;

the pensioner paying consumption taxes;

the compliant entrepreneur competing against someone who hides revenue;

the young worker facing high social contributions;

the household using deteriorating public services;

future taxpayers servicing additional public debt.

Tax evasion is often presented as an individual act against the state.

Economically, it is frequently an act against other taxpayers.

That distinction should fundamentally change the way we talk about it.

29. THE REAL EUROPEAN TAX RANKING SHOULD HAVE FIVE COLUMNS

Forget the simplistic league table based on the highest marginal rate.

A serious comparison should rank countries simultaneously by:

1. Gross income

How much does the average worker actually earn?

2. Effective labour taxation

How much of total labour cost is absorbed by taxes and social contributions?

3. Net disposable income

How much reaches the household?

4. Purchasing power

What can that net income actually buy?

5. Public-service value

How much healthcare, education, childcare, social protection and administrative efficiency does the citizen receive without purchasing it again privately?

And I would add a sixth:

6. Fiscal compliance

How evenly is the burden distributed between citizens who can and cannot conceal income?

Only then can we say whether a country is truly “high-tax” or “low-tax” from the citizen’s point of view.

30. THE FINAL PARADOX

A country can have high tax rates and still represent a relatively good bargain for its citizens.

Another can have moderate statutory rates and still impose a poor economic deal.

And a third can combine high taxes with widespread evasion, leaving compliant taxpayers trapped between the two.

That third model is perhaps the worst.

Because it destroys both economic efficiency and trust.

The honest worker sees an enormous deduction from his salary.

The state tells him that more resources are required.

He then sees another citizen apparently enjoying a comparable lifestyle on much lower declared income.

Eventually he asks the obvious question:

Am I financing public services — or am I also financing everyone who has found a way not to?

That question is politically explosive because in some countries there is no comfortable answer.

CONCLUSION: TAX EVASION DOES NOT MAKE TAX DISAPPEAR. IT CHANGES WHO PAYS IT.

This is the central argument.

Europe does not merely have a tax-rate problem.

It has, in several countries, a distribution-of-compliance problem.

People who receive fully documented salaries can be taxed with extraordinary efficiency.

People operating in less observable sectors have historically enjoyed greater opportunities for non-compliance.

The larger that gap becomes, the more the state must rely on those it can see.

And that produces the most perverse form of fiscal redistribution:

from the compliant to the non-compliant.

Nordic countries demonstrate something else.

Citizens can tolerate remarkably substantial taxation when institutions function, compliance is broad and the public sector visibly delivers value.

The comparison therefore should never be:

“Denmark has high taxes, therefore Denmark is bad.”

Nor should it be:

“Bulgaria has low personal income tax, therefore Bulgarians are better off.”

The intelligent comparison is:

What do you earn?

What does the state take?

What remains?

What can it buy?

What services do you receive?

And are the people around you contributing on broadly the same terms?

That final question may be the most important one of all.

Because progressive taxation can survive political disagreement.

High taxation can survive when citizens see value.

Even complicated taxation can survive reform.

What no fiscal system can indefinitely survive is the conviction among millions of compliant citizens that they are being asked to pay increasingly more precisely because others are being allowed to pay less.

Taxes are part of the price of civilisation.

But civilisation requires reciprocity.

If everyone receives the benefits, everyone who owes tax should contribute.

And if governments finally succeeded in significantly reducing the tax gap, societies would face an extraordinarily attractive choice:

lower taxes, better services, lower debt — or some combination of all three.

That is the real cost of tax evasion.

Not an abstract loss to the Treasury.

Not a number hidden in a government report.

It is the hospital that could have been better funded.

The teacher who could have been hired.

The debt that did not need to be issued.

The tax cut the compliant employee never received.

And the additional euro taken from someone who had already paid every euro he owed.

Tax evasion does not eliminate taxation.

It simply sends the bill to somebody else.

METHODOLOGICAL NOTE

The OECD tax wedge used in this article measures personal income taxes plus employee and employer social-security contributions, minus relevant cash benefits, relative to total labour costs. It should not be confused with the statutory marginal personal income-tax rate. In 2025 the OECD average tax wedge for a single worker without children earning the national average wage was 35.1%. (OECD⁠)

Tax-gap statistics should likewise not be interpreted as the percentage of individuals who are tax evaders. A tax gap measures the estimated difference between theoretical tax liabilities and amounts actually collected under a defined methodology. Errors, insolvencies and other forms of non-compliance may be included alongside deliberate evasion.

Comparability between national tax-gap figures remains imperfect. The United Kingdom has an unusually detailed official methodology, while other European countries do not publish an equally comprehensive annual estimate for personal income taxes. Artificially ranking every EU country by an invented “percentage of tax evaders” would therefore be misleading.

The United Kingdom is included as a European benchmark but has not been an EU member since 2020.
