No Corporation Tax payment on time

If you don’t pay your corporation tax on time, known as a late payment, or you do not pay enough (underpayment or non-payment), HMRC will charge your company interest. Late payment interest is charged from the day after the tax should have been paid (normally 9 months and one day after the end of the accounting period) until the date you pay it. Interest charges are automatic, however, interest is not charged on interest itself. Any late payment interest you pay to HMRC is deductible for tax purposes.
