Corporation tax return (CT600)

All UK Limited Companies must file a Corporation Tax Return (CT600) with HMRC within 12 months of their accounting period end. However, any Corporation Tax due must be paid within 9 months and 1 day of the financial year-end.

At Boobooks, we handle everything from notifying HMRC to calculating your taxable profits and preparing your CT600 submission. With our expert tax planning, you’ll stay compliant while minimising liabilities.

Not sure when your company’s tax year ends? We’ll help you stay on track and avoid late penalties.

Penalties for late filing of the CT600 company tax return

Missing your Corporation Tax Return deadline can result in steep fines from HMRC:

  • 1 day late – £100 penalty

  • 3 months late – Additional £100

  • 6 months late – 10% of your estimated tax bill (calculated by HMRC)

  • 12 months late – Another 10% of the estimated tax bill

Avoid these penalties by letting Boobooks manage your Corporation Tax compliance — on time, every time.
