Hi I'm Emily Coltman, chief accountant to FreeAgent where we make online accounting software for small service based businesses.

So, what dates does the Self Assessment tax return cover?

Well in the UK it covers a really weird set of dates, it's the sixth of April one year to the fifth of April the following year.

That's called the tax year or the fiscal year and whenever you put income on your tax return it will be the income that you had between those dates.

So if you had bank interest, or salary from a job then you'll get paperwork from the bank or from your employer telling you your income and any tax taken off between those dates.

If you're a sole trader who's not preparing their accounts to match the tax year, there's a bit more information below about accounting periods versus basis periods and which accounts you should put on your tax return.

FreeAgent can help you to fill in your tax return and for more information about that please do click the link above this video.

Thanks for watching and we'll see you in the next clip.
