Updated: The 2016 to 2017 form and notes have been added to this page.
The SA100 is the main tax return for individuals. Use it to file your tax return for income and capital gains, student loan repayments, interest, pensions, annuities, charitable giving and to claim tax reliefs and allowances.
You need to post your paper tax return to HMRC. If you miss the deadline, send your return online instead to avoid a penalty.
You may need to include supplementary forms for certain types of income.
