A familiar situation
A couple comparing household budgets can test combined income under a chosen effective tax rate. Use the marriage tax calculator as a broad scenario only; filing status and local tax rules can change the actual result.
How to use this calculator
- Enter your annual income, partner or spouse income, assumed combined effective tax rate.
- Select Calculate to see the answer and its breakdown.
- Keep a scenario, change an input and compare the results.
Use consistent units and check the assumptions below before applying the result.
How marriage tax is calculated
This combines the two annual amounts and applies one assumed effective rate. It does not model filing status, tax brackets, credits or separate state and local taxes. Formula: Combined estimate = (income 1 + income 2) × (1 − assumed effective rate). Use the displayed details to inspect the intermediate amounts and replace example assumptions with terms from your own quote or records.
Combined estimate = (income 1 + income 2) × (1 − assumed effective rate).Combining $80,000 and $60,000 at an assumed 22% effective rate yields an illustrative $109,200 after tax.
Assumptions & useful context
The two-person estimate uses one assumed effective rate and does not model filing-status rules.
Financial projections use your assumptions. Actual returns, lender terms, fees and tax rules can differ; these results do not guarantee a future outcome.
