2026/27 tax year

Check Marriage Allowance

Check the usual eligibility conditions and estimate the tax saving for a couple with standard Personal Allowances and employment or pension income.

Are you married or in a civil partnership?

Living together without being married or in a civil partnership does not qualify.

Which Income Tax rules apply to both of you?

If the partners have different taxpayer status, choose different or not sure.

This is the person giving up £1,260 of Personal Allowance.

This is the partner whose Income Tax may be reduced.

Does either partner receive Married Couple’s Allowance?

Marriage Allowance and Married Couple’s Allowance cannot be received at the same time.

Does either partner have other or more complex income?

Choose yes for dividends, savings interest, self-employment, property, foreign income, taxable benefits or a non-standard Personal Allowance.

Your answers are used only for this check. They are not added to a lead record or analytics event.

Assumptions and exclusions

This quick check assumes both partners have the standard Personal Allowance and only employment or pension income. It does not determine adjusted net income or model savings, dividends, benefits, self-employment, property, foreign income or special allowances.

Backdated claims are not totalled here. HMRC requires eligibility to be checked separately for each earlier tax year, using that year’s allowances and circumstances.

How to understand your result

Your result is an estimate for the tax year shown on the calculator. The breakdown lists each step, the rates and thresholds used, and the date the figures were last checked against GOV.UK. Amounts are rounded the way HMRC rounds them where a rule exists.

Each calculator lists what it leaves out, such as other income, reliefs or special cases, so read the assumptions before you rely on the figure. For your own position, check your HMRC online account or speak to a qualified professional.
