- 1 day late£100
Fixed penalty, even if no tax is owed
- 3 months£1,000
Plus £10 a day for up to 90 days
- 6 months£1,300+
Plus £300 or 5% of the tax due, if higher
- 12 months£1,600+
Another £300 or 5%, more in serious cases
Paying late adds interest and further 5% penalties on top.
Company accounts

Late by even one day
- 1 to 3 months£375
- 3 to 6 months£750

Each band replaces the last; the penalty is set by how late the accounts are.
Corporation Tax return (CT600)
HMRC · running total
- 1 day late£200
£1,000 if late three times in a row
- 3 months£400
Another £200 (or £1,000)
