The rates, thresholds and deadlines these sheets apply are HMRC's published figures for the tax year you select; everything else is arithmetic on the numbers you typed.

Self Assessment software in the UK does one thing the free tools on this site deliberately do not: it submits the finished return to HMRC over an authorised connection. Everything before that point, working out the profit, the allowances, the bill and the payments on account, can be done with a worksheet and checked by hand. So the question when choosing software is narrow: does it file, what does it cost for the pages you actually need, and does it carry your figures over to next year.

Decide whether you need software at all

HMRC's own online service files a Self Assessment return for nothing. Software earns its price when you have several income sources, want your figures carried forward, or file for more than one person, not simply because a return is due.

Check which supplementary pages it covers

A package that handles employment and self-employment may not handle property, partnership, capital gains or foreign income. The pages you need are decided by where your income came from, and a package that omits one of them is no use at any price.

Compare on filing and carry-forward, then price

The two things a worksheet cannot do are submit the return and remember last year. Those are what you are buying. Price the packages that do both for the pages you need, and ignore the feature lists that describe the arithmetic you can already check.

What somebody filing their own return asks about the Self assessment tax return software uk

Is HMRC's own service free?

Yes. Filing a Self Assessment return through HMRC's online service costs nothing and needs only a Government Gateway account. Commercial software exists for cases the online service handles badly, not as a toll on filing.

Does Taxyearvo file my return?

No. We compute and explain; we never file, and we never ask for your Government Gateway credentials. You take the figures our sheets produce and enter them into HMRC's service or into filing software.

What does Taxyearvo Pro add over the free sheets?

It keeps each tax year's figures so the next return starts from the last one, removes the watermark from what you print, and exports the workings. It does not file.
