Self Assessment: forms ordering
Phone
You can file your Self Assessment tax return online.
If you need a paper form you can either:
- download the SA100 tax return form
- call HMRC
If you need to tell HMRC about additional types of income, you can download all other supplementary pages.
HMRC does not supply blank tax return forms to agents.
If you cannot use the phone and need to order a SA100 tax return, you can ask someone you trust to order one for you.
Before you call us, find out about call charges.
