You can apply for Marriage Allowance if all the following apply:

  • you鈥檙e married or in a civil partnership
  • you do not pay Income Tax or your income is below your Personal Allowance (usually 拢12,570)
  • your partner pays Income Tax at the聽basic rate, which usually means their income is between 拢12,571 and 拢50,270 before they receive Marriage Allowance
