How will I send quarterly updates?

HMRC will expect you to send a summary of your business income and expenses to them every three months using MTD-compatible software.

The deadlines for submitting quarterly updates will be the same for everyone and will be effective from the start of the tax year on 6th April 2024 and will be required as follows:

Quarter        Period                          Deadline

      [1]                     6 April – 5 July                            5th August
      [2]                     6 July – 5 October                      5th November
      [3]                     6 October – 5 January               5th February
      [4]                     6 January – 5 April                     5th May

Finalising your business income

At the end of the tax year, you’ll need to finalise your business income by completing an end of period statement (EOPS) for each source of income, along with a final declaration that replaces the current Self Assessment tax return.

This process lets you confirm that the updates you’ve sent are correct, and to add any details about personal income or reliefs or make any other necessary adjustments

As with the current Self Assessment process, you’ll have to submit the EOPS and final declaration and pay the tax you owe by 31st January of the following tax year.

Tax payments

The tax liability will need to be paid by 31 January of the next year (as is currently the case).  You will be allowed to voluntarily pay your taxes as you go: the detail is still being decided.  Eventually, it is possible that you will be required to make four payments per year on account of tax.


HMRC have confirmed there will be no late filing penalties for at least a year while the new system beds in but they will return after that.  Penalties already apply for errors in returns or documents and interest is already charged on late payments.
