The tax year runs from 6th April to 5th April the next year, and under self-assessment it is up to the individual taxpayer to calculate their own tax liability and pay the tax due by the due date. Most UK residents are taxed under PAYE and do not have to complete a Self Assessment tax return.
However, the following people usually have to complete one…
• Anyone who is self-employed;
• A company director;
• A trustee;
• Pensioners with an annual income of £100,000 or more;
• Employees or pensioners with an annual income from savings or investments of £10,000 or more;
• An employee or pensioner with untaxed annual income of £2,500 or more;
• A landlord who rents out property or land.

If you are required to complete a return, they are normally issued to you at the beginning of April each year. The basic return is 10 pages, but many sources of income require supplementary pages to be completed as well. Some people receive a short tax return of only 4 pages.As well as your income it deals with the allowances and reliefs that you can claim.
Paper returns have to be filed by 31 October following the end of the tax year and HMRC will calculate your liability for you. For online returns you have until 31 January following the end of the tax year to file the return. If you file the tax return online through the HMRC website the software will calculate your tax liability for you.
If the return isn’t filed by the due date, there is an automatic fine of £100, which is reduced to the level of tax due if that is less. There is a further £100 fine if your return is still outstanding six months later.
The method of payment usually involves two payments on account of your tax liability as follows…
• one on 31 January during the tax year and
• another on 31 July following the tax year.
These are based on the net income tax and Class 4 NIC liability of the previous tax year .
A final payment (or repayment) is due on 31 January following the tax year.
Thereafter, there is a 5% surcharge on any taxes that remain unpaid after 28 February, and a further 5% on taxes not paid after 31 July.
The payments on account are not required if…
• income tax and NIC liability for the previous year (net of tax deducted at source) is below £500 (doubled to £1000 from 2009/10 with first payment affected being 31 January 2010) or
• more than 80% of the income tax and NIC liability for the previous year was tax deducted at source.
You can also apply to have the payments on account reduced if you expect your liability for a tax year to be less than the previous year.
HMRC can correct a self assessment return within nine months of the return being filed in order to correct any obvious errors or mistakes in the return and an individual can amend their self assessment at any time within 12 months of the filing date.
By law you must keep all records in support of the tax return for at least 22 months after the end of the tax year, but if you are self-employed or have rented property the records must be kept for five years and ten months after the end of the tax year.
You can be fined up to £3,000 if you fail to maintain or retain adequate records to back the return.
