How quarterly updates work: dispelling the four-tax-returns myth

If the phrase “quarterly reporting” makes you picture January’s tax-return job repeated four times, it helps to know what HMRC is actually asking for.

An MTD quarterly update is a summary of your business or property records. It is not a complete personal tax return, and it does not create a new quarterly tax-payment schedule.

There is still work to do: records need to be complete enough to support the update, and someone must review them. But that work can become part of a regular bookkeeping routine instead of four separate annual accounting exercises.

What goes into a quarterly update?

Your software adds up the relevant digital records and sends totals for the income and expense categories being used. Different reporting categories apply to self-employment, UK property and foreign property.

HMRC receives those summaries, rather than the individual receipts and invoices behind them. You still keep the supporting records in case they are needed. HMRC explains what quarterly updates contain.

For a sole trade, the standard categories cover items such as turnover, materials, vehicle and travel costs, and professional fees. A landlord’s categories reflect rental income and property expenses. The formal requirements are set out in HMRC’s quarterly update direction.

A category is a way of organising information. It is not a ruling that every transaction placed there qualifies for tax relief. Business purpose, private use and the tax rules still matter.

Some businesses can use simpler categories

Eligible self-employment and UK property sources with annual turnover below the £90,000 VAT registration threshold can use less detailed categorisation. Residential property finance costs must still be identified separately where relevant.

This reduces the reporting detail some people need. It does not remove the obligation to keep the underlying digital records. HMRC’s digital record-keeping direction explains the conditions.

Why the second update contains six months of information

The updates are cumulative. For standard periods, each one starts on 6 April and extends to the relevant quarter-end.

Suppose Priya runs a design business. Her records show:

Her first update contains £16,000 income and £4,000 expenses. Her second contains £34,000 income and £9,000 expenses, before considering any corrections.

The second update is not an additional report of only £18,000 and £5,000. It describes the year so far. The legal reporting framework is in the 2026 digital obligations regulations.

For your own management reports, it can still be useful to compare each three-month period separately. Just distinguish that business comparison from the cumulative figures sent to HMRC.

Do you need to finalise the tax calculation every quarter?

You do not have to complete accounting or tax adjustments before sending a quarterly update. Year-end work remains a separate part of preparing the final annual position.

That can include correcting private-use proportions, dealing with capital expenditure under the relevant rules, considering losses and making appropriate claims. HMRC provides a separate process for adjusting self-employment and property income.

This is a useful boundary. You should check for missing transactions, obvious duplicates and amounts posted to the wrong business before submitting. You do not need to turn every quarterly review into a full year-end accounting exercise.

Where a purchase needs judgement, keep the supporting invoice and a note of the question. A bank description alone may not tell you whether it was an ordinary repair, a new asset or partly personal spending.

What happens if you find an earlier mistake?

Suppose Priya discovers in September that an April software subscription was entered twice. She corrects the underlying record. Her next cumulative update can reflect the corrected totals for the year so far.

That is one reason to correct records at their source, rather than altering a total on a separate sheet and leaving the original entries wrong.

After the fourth update, further record corrections may require that update to be resent before the annual return is completed. Follow the process in your software and the relevant HMRC guidance. Keep enough information to explain what changed.

Four quarterly deadlines do not mean four tax demands

The update deadlines are 7 August, 7 November, 7 February and 7 May. For 2026/27, the first deadline was 7 August 2026 and the fourth is 7 May 2027.

These are reporting dates. The normal Self Assessment payment rules continue. Where payments on account apply, the instalments usually fall on 31 January and 31 July; the balancing payment follows the annual calculation. Read HMRC’s payments on account guidance.

For example, a taxpayer whose relevant bill is £8,000 might have two £4,000 payments on account towards the following year, subject to the normal rules. Sending an August update does not itself add a third instalment.

Keep a tax reserve based on a sensible forecast, and revisit it as your business changes. An in-year software estimate can help, but it may not yet reflect all income, reliefs or adjustments.

What if you have a trade and a rental property?

You normally send separate updates for each self-employment business, your UK property business and your foreign property business, where those sources are within your digital obligations.

A sole trade plus a UK rental business therefore usually means two updates at each quarterly deadline. Three UK rental properties held personally ordinarily sit within one UK property business, rather than producing three separate quarterly submissions.

After the year ends, your annual return brings the overall position together. Other taxable income and gains must also be included. For 2026/27, the annual return deadline is 31 January 2028. See HMRC’s annual return process.

A review routine that makes submission easier

Try to resolve questions while the transactions are still familiar:

• Check that the bank feed or imported file covers the period you intended.
• Add cash income and business costs paid through other accounts.
• Review suggested categories and identify personal transfers.
• Reconcile amounts received through agents or payment processors.
• Review the summary for the correct business and reporting period.
• Confirm submission succeeded and retain the acknowledgement.

Avona AI helps categorise transactions in Avona.app, reducing repetitive sorting. It cannot know every purchase’s purpose or replace the information you hold about your business.

The final submission can be quick when records are already in order. The total time depends on how many transactions you have, their complexity and the corrections needed.

Start with the records you already have

You do not need to become an accountant to understand a quarterly update. Start with complete records, review the summary and keep the annual return in view.

Explore Avona.app at £15/month if you want to manage the process yourself. A regular review habit gives the software good information to work with and makes each deadline a smaller task.
