SELF ASSESSMENT - 30 SEPTEMBER DEADLINE
If you want Revenue & Customs to calculate how much tax you owe and you don’t file your tax return online then you must submit your return by the end of this month.
The end of September is also a key date if you are a pay-as-you-earn taxpayer who owes the Revenue less than £2,000. You can have your pay code adjusted if you file by post before the end of September. This means that you will spread the tax owed over the following year instead of paying a lump sum at the end of January 2006.
