Your company or association must file a Company Tax Return if you get a ‘notice to deliver a Company Tax Return’ from HM Revenue and Customs (HMRC).
You must still send a return if you make a loss or have no Corporation Tax to pay.
When you file your tax return, you work out your:
You can either get an accountant to prepare and file your tax return or do it yourself.
If you have a limited company, you may be able to file your accounts with Companies House at the same time as your tax return.
There’s a separate deadline to pay your Corporation Tax bill. It’s usually 9 months and one day after the end of the accounting period.
You’ll have to pay penalties if you do not file your Company Tax Return by the deadline.
|Time after your deadline||Penalty|
|3 months||Another £100|
|6 months||HM Revenue and Customs (HMRC) will estimate your Corporation Tax bill and add a penalty of 10% the unpaid tax|
|12 months||Another 10% of any unpaid tax|
If your tax return is late 3 times in a row, the £100 penalties are increased to £500 each.
If your tax return is 6 months late, HMRC will write telling you how much Corporation Tax they think you must pay. This is called a ‘tax determination’. You cannot appeal against it.
You must pay the Corporation Tax due and file your tax return. HMRC will recalculate the interest and penalties you need to pay.
If you have a reasonable excuse, you can appeal against a late filing penalty by writing to your company’s Corporation Tax office.
