Making Tax Digital for Income Tax, without the accounting software
TaxQuarter does one job. It keeps the income and expense records your updates are made from, sends your four quarterly updates and your final declaration to HMRC, and nothing else. For sole traders and landlords.
Runs on HMRC's test service. HMRC has closed production access to new quarterly update software for 2026 to 2027, so nothing sent from TaxQuarter reaches a real tax record yet.

- These figures replace the ones sent on 28 July 2026: each update restates the whole year so far.
- Records dated after 5 October 2026 go into the next update.
Four quarterly updates, then a final declaration
Each quarterly update restates your income and expenses from 6 April to the end of the quarter. TaxQuarter adds up your records for that period and sends the totals in HMRC's own categories. After the year ends, it asks HMRC for your calculation and sends the declaration once you agree to it.

These are HMRC's standard dates for the 2026 to 2027 tax year. Once you connect, your dashboard shows the dates HMRC holds for you.
HMRC's reply, kept with your records
When HMRC accepts an update, TaxQuarter shows its reply at once: the response, the reference HMRC's support team asks for, and the in-year estimate HMRC starts working out. A copy of what was sent and what came back is kept as your evidence of filing, and every update you have sent is listed with HMRC's reply.
If HMRC turns an update down, you see its own code and message, word for word, and the attempt is kept too.
Demo: nothing was sent. The references are samples; in TaxQuarter they are HMRC's own.
Sent to HMRC
HMRC replied 204 No Content, which means it accepted the update. It can take up to an hour for HMRC to mark it as received.

Tax estimate
HMRC is working out an in-year estimate. Its reference is:
a3f0c6d2-91b8-4e57-b2c4-7e1d8f5a0c96
This estimate is based only on the information submitted so far. It is not your final tax bill.
Built the way HMRC asks
- Two-factor sign-in on every account
- HMRC's fraud prevention rules ask filing software to report how each person proved who they are, so every account uses an authenticator app. It cannot be switched off.
- Fraud prevention data on every call
- The law requires filing software to send HMRC sixteen headers describing the device and connection a filing comes from. TaxQuarter sends all sixteen, and HMRC's own validator reports no errors in them.
- Whole pence, from record to return
- Amounts are kept as whole pence and turned into pounds once, as the update is built, so nothing drifts by a penny on the way to HMRC.
- Deadlines only from HMRC
- Every deadline on your dashboard comes from HMRC's obligations service. TaxQuarter never works one out from a calendar of its own.
Who it is for
- Sole traders and landlords who have to file under Making Tax Digital for Income Tax.
- One or two income sources: self-employment, UK property, or both.
- Anyone who would rather file themselves than hand a year of paperwork to an accountant.
It is not for agents filing for clients, and this version does not cover foreign property.
