A million businesses face their first Making Tax Digital quarterly deadline on 7 August. Most will see it as another compliance task. The smarter ones will recognise it as a new way to make better business decisions.
A million businesses face their first Making Tax Digital (MTD) for Income Tax deadline on 7 August.
Most will miss the point.
Quick question: could you say, right now, roughly what your tax bill will look like next January?
If the answer is no, you’re in good company. Most self-employed business owners set aside “roughly a third” and cross their fingers.
But that approach is becoming outdated.
For businesses enrolled in Making Tax Digital for Income Tax, the new quarterly reporting cycle delivers something far more valuable than another filing deadline. In the right hands, it could become a genuine growth tool.
The deadline is the least interesting part
By 7 August, around a million sole traders and landlords must submit their first quarterly update under Making Tax Digital for Income Tax.
The update is simply a digital summary of income and expenses submitted to HMRC through compatible software, covering the tax year since 6 April. It must be completed four times a year, every year.
Most businesses will treat it as another administrative obligation. Technically, that’s enough.
But every submission triggers something far more useful. HMRC sends back an estimate of the tax you’ve accrued so far, based on your actual figures.
Think about what that means.
The old system told you what you owed after the tax year had ended, when there was little left to influence the outcome. This system gives you that visibility in August, with months still available to improve cash flow, set money aside or make informed financial decisions before the tax year closes.
And you’ll receive that updated picture four times every year.
That’s only the starting point.
You can submit updates more frequently if you choose—even weekly—and every submission refreshes your estimated tax position.
For the first time, many sole traders will have access to something approaching a live tax forecast. Ironically, it’s generated by the organisation that ultimately calculates the bill.
Larger businesses have relied on this kind of financial visibility for years. Now it becomes a by-product of meeting your minimum legal obligations.
A discipline ambitious businesses already understand
The quarterly reporting cycle also forces something many business owners rarely prioritise: regularly reviewing their numbers.
Four times a year you’ll sit down with your income and expenses and ask whether the business is performing as expected.
You’ll notice spending creep before it becomes a problem. You’ll see whether that price increase actually improved margins. You’ll identify seasonal slowdowns while there’s still time to respond.
The advantages extend beyond day-to-day management.
Proving self-employed income to a lender has traditionally meant relying on accounts that might be up to two years old. Quarterly submissions create a much more current financial record. That can strengthen applications for mortgages, vehicle finance or business lending, particularly when your current trading is outperforming your last tax return.
And if October reveals you’re heading for a particularly profitable year, you still have time to act before 5 April. You might bring forward equipment purchases, increase pension contributions or think more carefully about the timing of invoices.
None of this is aggressive tax planning.
It’s simply the kind of sensible financial management that growing businesses have always practised. MTD just makes it easier for everyone else to do the same.
Is your software ready? More importantly, are you?
Choosing the right software matters.
MTD-compatible for VAT does not automatically mean compatible with MTD for Income Tax. They are completely different systems.
Start by checking your software against HMRC’s recognised list for Making Tax Digital for Income Tax.
But be careful here too.
“HMRC-recognised” is a tick-box rather than a gold star. It confirms the software meets minimum technical requirements, not that it handles every part of the process.
Make sure it supports both quarterly updates and the final year-end submission, and check it covers your income sources, whether that’s self-employment, property income or both. Some products only support one.
Then comes the more important question.
Are you ready?
The rules require digital records. Your income and expenses need to live in software rather than a carrier bag of receipts and a spreadsheet held together by good intentions.
Fortunately, the transition is often quicker than people expect. Connect your bank feed, categorise transactions, review the figures and submit. There is even HMRC-recognised software available at no cost, including Sage Sole Trader Free.
There are no late-filing penalty points during this first year, so treat 2026/27 as a dress rehearsal.
Just don’t mistake a soft landing for a reason to drift.
Which business are you building?
The 7 August deadline isn’t really about compliance.
It’s a sorting mechanism.
Some businesses will submit their update, tick the box and carry on exactly as before.
Others will realise they’ve been given something far more valuable: regular financial visibility that helps them make better decisions while there’s still time to influence the outcome.
The software may be mandatory.
What you do with the information is entirely your choice.
