Two-Country Tax Comparison
Use the same income for both countries and enter the combined rates you expect to pay. The output compares net income and shows the annual gap before any treaty relief.
Rates, contribution caps and bases differ by country and income level. Use effective rates for your situation and verify them with an official source.
Rates are averages, not brackets
A progressive income tax has several rates and a contribution has a cap. Entering the top rate for both countries exaggerates the difference; the useful input is the effective rate that applies to the income you expect.
The same applies to social contributions, which may stop at a ceiling. If the income is above that ceiling, the effective contribution rate is lower than the headline rate.
What the comparison leaves out
Net income is not the whole story. Local taxes, mandatory insurance, pension entitlements and the cost of services differ, and some of them are worth more than the gap in cash.
Treaty relief is also excluded here, because it depends on residence and income type. The figure is the starting gap, not the final answer for a cross-border case.
Frequently asked questions
Should you use marginal or effective rates?
Use effective rates for a like-for-like comparison of the same income. Marginal rates describe the next unit of income, not the average burden.
Does the comparison include local taxes?
Only the rates you enter. Local or regional taxes can be added to the income tax field if they apply to the whole income.
Is the country with the lower rate always better?
Not necessarily. Contributions buy different entitlements, and living costs and services are outside the calculation.
