How Does HMRC Marriage Allowance Work
Here’s an example of how the HMRC marriage allowance works when you are self-employed.
Mary went self-employed in the tax year 2018/2019 and the profits from her business were £5,000 as she was in the start-up phase. Her partner Jo was in full-time employment and pays tax at the basic rate.
Under the rules of HMRC marriage allowance, Mary can transfer up to 10% of her unused personal allowance to Jo of £1,185 for 2018/2019 (£11,850 x 10%).
By transferring this Jo’s personal allowance increases to £13,035 (£11,850 + £1,185).
This equates to a tax saving of £237 at 20%.
Claiming Backdated HMRC Marriage Allowance
