A question came up recently that we see asked constantly in forums, community groups, and comment sections across the internet. Someone had just found out they were required to join Making Tax Digital for Income Tax, and their immediate reaction was panic. “Does this mean I have to pay my tax four times a year now?”

It is one of the most common misunderstandings around MTD, and it is worth clearing up properly because the confusion is causing real stress for people who simply do not need to be stressed about this particular thing.

The short answer is no. Quarterly updates do not mean quarterly tax payments. Your payment dates are not changing.

So what actually is a quarterly update?

Under Making Tax Digital for Income Tax, you are required to submit a summary of your income and expenses to HMRC every three months. That is it. You are telling HMRC what came in and what went out during that period, using software that connects directly to their systems.

You are not calculating a tax bill. You are not making a payment. You are not filing a mini tax return. You are simply keeping HMRC informed of how your finances are moving throughout the year, in the same way you might update a spreadsheet, except it goes directly to them.

Think of it like sending a regular progress report to a colleague rather than submitting a final piece of work. The final piece of work, which is your end of year declaration, still comes once a year. That is where everything gets finalised.

When do the quarterly deadlines actually fall?

The four submission deadlines each year are the 7th of August, the 7th of November, the 7th of February, and the 7th of May. Each one covers the three month period that just ended.

Miss one? In the first year of MTD, which is the 2026 to 2027 tax year, HMRC has confirmed there are no penalty points issued for late quarterly submissions. It is a soft landing period designed to give people time to adjust. From the following year, a points based system kicks in, but even then it takes four late submissions within two years to trigger a financial penalty of £200. It is not a cliff edge.

When do you actually pay your tax?

Nothing changes here. If you currently make payments on account, those still fall on the 31st of January and the 31st of July. Your balancing payment is still due on the 31st of January following the end of the tax year. Exactly as it has always been.

The quarterly updates feed into HMRC’s systems and give them a clearer, more current picture of your finances throughout the year. That is useful for you too, because your software will be able to give you a running estimate of what your tax bill is likely to be, rather than one big surprise in January.

Why does this confusion keep spreading?

Partly because the name is misleading if you do not know what it means. Quarterly reporting sounds like it could involve money changing hands. Partly because the guidance from HMRC has not always been written in plain language. And partly because when something changes in the tax system, the instinct is to assume the worst.

The reality is that the core change here is about timing and format of information, not about when or how much you pay. You are moving from reporting once a year in arrears to reporting four times a year as you go. For many people, once they are set up and in a rhythm, that actually turns out to be less stressful than the annual scramble.

A quick summary

Quarterly updates are reporting submissions, not tax payments. Your tax payment schedule stays the same. In the first year there are no penalties for late quarterly submissions. From year two a points system applies but a fine only triggers after four late submissions in two years.

If you are a landlord or self-employed and your gross income is above £50,000, MTD applies to you from April 2026. The first quarterly deadline is the 7th of August 2026, covering the period from the 6th of April to the 5th of July.

Getting set up with the right software is the main thing to sort before that date. Once that is in place, the quarterly update itself takes minutes.
