Marriage Allowance Transfer Estimator UK

What Is the Marriage Allowance in the UK?

The UK’s Marriage Allowance allows one partner in a married couple or civil partnership to transfer a portion of their unused Personal Allowance to the other partner, resulting in tax savings of up to £252 per year (based on current rates).

Eligibility Criteria

• You’re married or in a civil partnership
• Your income is below the standard Personal Allowance (e.g. £12,570)
• Your partner’s income is below the basic tax rate threshold (e.g. under £50,270)

How It Works

If you're not using your full Personal Allowance, you can transfer up to 10% of it (currently £1,260) to your spouse or civil partner. This reduces their tax bill by up to £252 per year.

Real-Life Examples

Example 1: Sam earns £8,000 while Alex earns £30,000. Sam isn’t using their full allowance and transfers £1,260 to Alex. Alex’s tax reduces by £252.
Example 2: Rita earns £11,500 and isn’t eligible to transfer because she has used most of her allowance.
Example 3: Jon earns £15,000 and attempts to transfer — not allowed, as income is above the threshold.
