- Tick the extra pagesTick anything else that applies, such as items under Savings, pensions and giving and Additional Pages this year (student loan, Child Benefit, capital gains, residence). Use the 2 Extra pages tab for the less common pages.
- SaveChoose Save and close. Each ticked topic now appears as a step to fill in.
Filling in a page
Each topic opens a short set of questions. Choose Save and add another if you have more than one of the same thing, such as two jobs, or Save and Close when you are done.
The common boxes are shown first. Less common HMRC boxes sit under More HMRC boxes for this step, so open that only if you need it.
Ticking a choice saves straight away. Typed amounts are saved when you save the page, or when you choose Save and finish later.
Removing a page you do not need
Open Change pages on this return and untick the page. An empty page does not stop you preparing, but a ticked page must be complete before you can file. The filing checks list any page that is ticked but not finished.
Still stuck?
- A page shows as not complete on the filing desk? Open it and fill the missing boxes, or untick it if it does not apply.
- Not sure whether income needs a page? The guided questions ask about each type of income in turn.
- Partnership boxes still at £0.00? They fill in once the partnership statement is finished.
Still not sorted? Contact us and tell us the page, the tax year and any message you see.
Questions answered
What are supplementary pages?
They are extra pages that sit with the SA100 main return for income it does not cover, such as employment (SA102), self-employment (SA103), UK property (SA105) and capital gains (SA108).
Do I need a supplementary page for bank interest?
No. UK savings interest, dividends, pensions and Gift Aid go on the main SA100. Foreign interest goes on SA106.
Does every employed person need SA102?
If you file a return and had a job in the tax year, you normally include an SA102 for each employment, even if tax was taken through PAYE.
Can I add a page after I have started?
Yes. Open Change pages on this return at any time before you file and tick the page.
Does adding pages change the price?
The pages under How you earned set the plan you pay for when you file: employment, self-employed and property, or partnership. Preparing stays free.
