No. MTD quarterly updates report income and expenses; they are not quarterly Income Tax bills. Your tax payments, any payments on account and the fee you pay your accountant are separate. Check your HMRC statement for the amounts and dates you actually owe.
Three different things can appear on your screen
- A quarterly update: business or property figures sent to HMRC.
- An estimated tax figure: a working view that can change before the annual return is final.
- A service invoice: the accountant or software provider’s charge.
Paying one does not settle the others. Check the payee and description before making a payment.
Which dates matter for tax payments?
The annual balancing payment is normally due by the following 31 January. Payments on account can also be due in January and July. Use your HMRC statement to see what actually applies; MTD does not turn every quarterly update into a demand for one quarter of your estimated annual tax.
For example, a November update and a November accountant’s invoice do not, by themselves, create a new November Income Tax bill. You may still want to set money aside, but savings in your bank are different from tax paid to HMRC.
Use the estimate to plan, not to guess a payment
Ask what income, reliefs and adjustments are missing from the estimate. If you have a PAYE job, rental income or other investments, the trade’s figures alone may not explain the eventual personal bill. Keep your payments-on-account schedule with the records you share with the accountant.
Label the payment before you make it
Suppose your accountant charges £40 a month and the software shows an estimated £3,600 annual tax figure. Twelve service payments of £40 total £480 paid to the provider. They do not reduce the £3,600 estimate or count as tax paid to HMRC.
Keep a simple payment list: payee, reference, amount, due date and confirmation. Use HMRC’s actual statement for tax amounts due. Do not divide the estimate by four and assume the result is a quarterly bill.
An update estimate is not a payment instruction
Illustrative example.
A fictional sole trader sees a £2,400 estimate after an update and assumes a £600 payment is due immediately because there are four quarters. That division does not establish any legal payment obligation. The estimate may change as records and other income are added.
Keep three separate records: the update sent, the current estimate and the actual amounts and dates HMRC says are payable. A savings transfer you make for budgeting is your own planning decision, not evidence of a new quarterly tax-payment deadline.
| Check | Practical action |
|---|---|
| Quarterly update | Check the reporting period and successful submission. |
| In-year estimate | Use as provisional planning information, with its limitations. |
| Payment liability | Check the actual HMRC statement, payment dates and amounts. |
Should I divide the estimate by four and pay that?
Not as a way of determining what is legally due. Check the actual liability and payment timetable separately.
Can I put money aside monthly?
Yes, budgeting is separate from when HMRC requires payment. Revisit your savings plan as better information becomes available.
