Questions about Marriage Allowance

Is the saving always £252?

No. £252 is the maximum. The lower earner can create tax by giving up allowance, so the useful measure is the couple’s combined change.

Can a higher-rate taxpayer receive the transfer?

No. The recipient must remain within the applicable basic-rate limit, with a different income ceiling used for Scottish taxpayers.
