Couples and assessment
German Joint Tax Assessment and Ehegattensplitting
Qualifying spouses can be assessed jointly under Germany’s splitting method. The calculation does not simply apply a special flat rate: it calculates tax on half of joint taxable income and doubles the result.

The statutory splitting calculation
Section 32a of the German Income Tax Act calculates joint income tax as twice the tax due on half of the couple’s combined taxable income. Because the tariff is progressive, the result can differ from adding two individual assessments.
The difference is often more noticeable when the spouses’ taxable incomes are unequal, but eligibility and the complete return still determine the final result.
Example: For €80,000 of combined taxable income, the tariff is applied to €40,000 and the resulting income tax is doubled.

Check eligibility before combining a household
Section 26 generally permits the choice for spouses when both meet the specified unlimited-tax-liability conditions, are not permanently separated, and those conditions existed at the start of or arose during the assessment year. Cross-border cases can involve section 1a and need a separate eligibility check.
Sharing an address or a bank account does not itself establish eligibility. ToolsFA accepts the assessment option you select; it does not verify marriage or partnership status, separation dates, residence, treaty treatment or any special eligibility rule. Confirm those facts before interpreting a joint result.

Worked 2026 tariff comparison: unequal taxable incomes
For an isolated tariff exercise, assume the spouses qualify and their correctly established individual taxable incomes are €60,000 and €20,000. Under the ordinary 2026 tariff, individual income taxes are €14,233 and €1,570, totaling €15,803. Joint taxable income is €80,000; tax on half (€40,000) is €7,209, doubled to €14,418. The tariff-only difference is €1,385.
These amounts exclude solidarity surcharge, church tax, credits, progression-reservation income and other special rules. They are not a promised refund: withholding must still be reconciled. The example starts with taxable income after valid deductions, not gross salaries to copy directly into an employment-income field.
Example: Individual tariff: €14,233 + €1,570 = €15,803. Joint tariff: 2 × €7,209 = €14,418. Difference: €1,385 before other assessment items.

How to enter a joint estimate
Add both spouses’ relevant income, deductions and taxes withheld. Do not enter the same household deduction twice or treat a payroll tax class as the final annual tax result.
Choose the calculator’s joint-assessment option only for a scenario that qualifies for Zusammenveranlagung. Enter combined gross employment income and supported other taxable income, then enter the applicable deductible work-expense or allowance total and deductible pension/insurance contributions in their separate fields. The tool does not automatically add employee allowances or validate deductible amounts.
Press Calculate estimate, check the derived taxable income, and compare income tax, Soli and church tax with the corresponding prepaid totals. The tool applies the 2026 splitting tariff and simplified surcharge calculations; it does not allocate deductions between spouses, model every credit or church-tax circumstance, or prepare an ELSTER return.
- ✓ Combine both gross incomes—not just one spouse's wages
- ✓ Combine applicable eligible deductions once; do not add an allowance again when already included
- ✓ Combine Lohnsteuer withheld
- ✓ Keep Soli and church tax in their separate fields
Compare two individual estimates with one joint estimate
For a planning comparison, first run one individual scenario for each spouse using that person's income, properly attributed deductions and tax withheld. Record each estimated liability and filing balance. Then run the eligible joint scenario with the combined figures and compare its liability with the sum of the two individual liabilities.
Do not compare the joint household result with only one spouse's individual calculation. Keep the same tax year and underlying records, and obtain the proper allocation where deductions or special income items cannot simply be added. Compare liabilities before comparing refunds so a withholding difference is not mistaken for a tax saving.
Payroll classes and annual assessment
German payroll tax classes influence withholding during the year; they do not replace the final annual assessment. A couple may therefore receive a refund or owe tax even when monthly payroll deductions appeared reasonable.
Use the annual documents for both spouses and confirm the final treatment through ELSTER or professional advice when circumstances are complex.
Frequently asked questions
Does selecting joint assessment prove we qualify?
No. The calculator does not test the legal conditions. Confirm the applicable section 26 conditions and any cross-border or special rules before using a joint scenario.
Should I enter half the household income in joint mode?
No. Enter the combined relevant income and deductions once. The joint tariff itself halves taxable income for the calculation and doubles the resulting tax.
Does joint assessment always reduce tax?
Not always. The effect depends on income distribution and the couple’s complete tax circumstances.
Do tax classes determine final annual tax?
No. They primarily affect payroll withholding; the annual assessment determines final liability.
Can I enter only one spouse’s withholding?
For a joint scenario, combine the relevant withholding for both spouses.
