Q. When does my self assessment tax return have to be filed by?

A. If you want the Inland Revenue to calculate any tax you may owe you must submit your return by 30th September following the end of the tax year to which it relates. If submitted by this date and you are a Schedule E tax payer and your liability is less than £2,000 , you may elect for any liability to be collected through your tax code of the following year.
If you are calculating your tax liability yourself, or have an agent who does this for you, the deadline is 31st January following the end of the tax year.

Q. When must I pay my tax liabilities?

A. All tax outstanding is due by 31st January following the end of the tax year to which it relates.
Depending on your total tax liability, you may also have to make payments on account towards the current year's tax liability. These are based on your previous year's liability and are split into two equal instalments which must be paid by 31st January in the tax year and by 31st July following the end of the tax year. Should your actual liability turn out to be larger than the payments on account already made, then the balancing payment must be made by the following 31st January.
In certain circumstances you may be able to reduce your payments on account.

Q. Are there any penalties for not submitting my self assessment return on time?

Q. What if I don't pay outstanding tax by the due dates?
