Before you start

You can transfer up to £1,260 of your Personal Allowance to your spouse or civil partner if you don't pay Income Tax and your partner is a basic-rate taxpayer.

Step by step

Open Reliefs & adjustments, under Settings.
Check you can transfer: you can transfer up to £1,260 of your Personal Allowance to your spouse or civil partner if you don't pay Income Tax (or your income is below your Personal Allowance) and your partner is a basic-rate taxpayer. You only need to do this once: HMRC carries it forward each year.
Read the one-way note: HMRC only lets software create the transfer, so it does not show in EasyTaxer afterwards and you cannot cancel it from EasyTaxer. To check, change or cancel it later, sign in to your HMRC online account.
Enter your partner's National Insurance number and surname. Their first name and date of birth are optional.
Check the details, then select Transfer my allowance. EasyTaxer sends the transfer to HMRC and confirms it has been submitted. If HMRC rejects it, you see HMRC's own message.

Who can transfer

You can transfer up to one thousand two hundred and sixty pounds of your Personal Allowance to your spouse or civil partner, if you don't pay Income Tax and your partner is a basic-rate taxpayer.
It's one-way

The transfer is one-way in EasyTaxer. To check, change or cancel it later, you sign in to your HMRC online account.
Your partner's details

Enter your partner's National Insurance number and surname. Their first name and date of birth are optional.
Transfer

When the details are right, select Transfer my allowance. EasyTaxer sends the transfer to HMRC and confirms it's been submitted. Check first, because you can't undo it in EasyTaxer.
