What HMRC asks for

GoSimpleTax field

20 DTA income for which partial relief is claimed

The amount of double taxation agreement income for which you are claiming partial relief. You need Helpsheet 304. You also need to complete and send in the claim form included in the helpsheet.

The matching amount field on the Residence in other countries tab

21 Relief under DTAs because an agreement awards residence to another country

Only enter the amount of UK tax deducted. You need Helpsheet 302. You also need to complete and send in the appropriate claim form from the helpsheet.

The matching amount field on the Residence in other countries tab

22 Relief claimed because of other provisions of the relevant DTAs

Only enter the amount of UK tax deducted. You need Helpsheet 304. You also need to complete and send in the appropriate claim form from the helpsheet.

The matching amount field on the Residence in other countries tab

If you claim relief in box 21 or box 22, fill in the claim form in Helpsheet 302 or 304 and send it as well. All money boxes are in whole pounds.

Attachments in GoSimpleTax are not sent to HMRC, so you must send the claim form to HMRC yourself.

Temporary non-residents, income and capital gains

When you return to the UK after a period of temporary non-residence, you may be charged tax on certain income and gains that arose or were remitted during that period. The rules depend on the tax year you left the UK.

  • Income Tax, left in 2012–13 or an earlier year: see HMRC6.

  • Income Tax, left in 2013–14 or a later year: see RFIG21510 onwards. Search for 'RFIG21500' on gov.uk.

  • Capital Gains Tax: search for 'HS278' on gov.uk.
