The important dates for taxpayers are: Dates for the Tax Return 6th April – The tax year This starts on 6 April and ends on 5 April: so the tax year 2001-02 starts on 6 April 2001 and ends on 5 April 2002. 30 September – Deadline for sending in your tax return. If you want IR to work out your tax bill you should fill in your return and send it in by 30 September after the end of the tax year. IR will still calculate your tax bill after this date but they cannot guarantee to tell you how much to pay by the end of January. You should also send in your tax return by 30 September if you want any tax you owe (less than £2000) included in the following year’s tax code. Remember, if you submit your Tax Return over the Internet all the Software and Online forms will calculate your tax liability for you. 31 January – Final deadline for sending in your tax return. If you decide to work out your tax bill yourself you must fill in your return and the calculation and send your Return in by 31 Janua
