If you ship your return after the filing date, HMRC can’t guarantee to calculate your tax bill and tell you the outcome in time for any 31 January payment.
If you would like to figure out your tax invoice, or if your paper return is late, you can ask the HMRC for their Tax Calculation Summary notes and pages to help you work out your tax bill.
The number to contact HMRC on for this is 0845 9000 404. You don’t need to send the supplementary pages HMRC sends you within your tax return.
