Why Making Tax Digital Matters: What’s the Point of MTD for Income Tax (2026–2028)?

If you’re asking, “Why do I have to do Making Tax Digital — what’s the point?”, you’re not alone. For many self-employed people and landlords, MTD can feel like extra admin, extra cost, and a change you didn’t ask for. The practical answer is that HMRC is changing how Income Tax is reported, and from 2026 onwards more people will have to keep digital records and send regular updates.

But there is a point — and it’s worth understanding it properly so you can plan calmly, choose the right software, and avoid last-minute stress. In this guide we’ll focus on the 2026 rollout of Making Tax Digital for Income Tax Self Assessment (MTD for ITSA), what it means in real life, and how to get ready without it taking over your business.

What is Making Tax Digital (MTD) — in plain English?

Making Tax Digital is HMRC’s programme to move tax reporting away from annual, paper-based or spreadsheet-only processes and towards digital record keeping and regular submissions using compatible software.

For Income Tax, MTD for ITSA changes two big things:

• How you keep records: you’ll need to keep certain records in a digital form (typically within accounting software).
• How often you report: instead of only sending one tax return per year, you’ll send quarterly updates during the year, plus an end-of-period statement and a final declaration.

When does MTD for Income Tax start? (2026–2028 timeline)

MTD for ITSA is being phased in based on your gross income from self-employment and/or property (before expenses). The key dates are:

If you’re not sure where you sit, it’s worth checking your last submitted tax return and looking at your turnover/rents received figure(s). Many people assume they’re under the threshold because their profit is lower — but the test is based on income before expenses.

So… why is HMRC doing this?

HMRC’s stated aim is to create a tax system that is:

• More accurate (fewer mistakes from manual entry and missing paperwork)
• More up to date (information is sent during the year, not long after it ends)
• More efficient (less paper, fewer calls and corrections, more standardisation)

There’s also a wider driver: HMRC wants to reduce the “tax gap” — the difference between the tax that should be paid and what is actually collected — much of which comes from error and poor record keeping rather than deliberate evasion.

Whether you find that convincing or not, the practical reality is simple: MTD for ITSA will become the required method of reporting for many self-employed people and landlords. The “point” for you is making sure you stay compliant without paying more tax than you need to.

What changes for you in practice?

Under MTD for ITSA, you’ll typically have these obligations:

1. Digital records: keep your income and expenses recorded digitally.
2. Quarterly updates: send updates to HMRC four times a year for each business (and for property income).
3. End of period statement (EOPS): confirm your final figures after the tax year ends (similar to finalising accounts).
4. Final declaration: submit the final confirmation for the year (this replaces the current Self Assessment submission).

This is a shift from “do it all once a year” to “keep it tidy as you go”. For some people that will feel like more admin. For others, it can actually reduce the annual scramble.

What’s the point for you (not HMRC)? The real-world benefits

Even if you wouldn’t choose this change, there are some genuine upsides when it’s set up properly.

1) Fewer nasty surprises at tax time

If your records are updated during the year, you’re far less likely to get to January and realise you’ve under-saved for your tax bill. Regular updates make it easier to estimate what you’ll owe and plan your cash flow.

2) Better grip on your business numbers

Most self-employed people don’t need complicated reports — but it does help to know, month by month, whether you’re actually making money. With consistent records, you can see patterns: which months are quiet, where costs are creeping up, and what you can realistically take out of the business.

3) Less time spent chasing missing receipts

When you capture costs as you go (even just snapping receipts into an app), you avoid the end-of-year hunt through emails, bank statements, and glove compartments.

4) A clearer audit trail if HMRC ever asks questions

Most HMRC checks are about clarity: “Where did this figure come from?” Digital records with attached evidence make it easier to answer quickly and confidently.

5) You’re less likely to miss allowable expenses

When you record costs regularly, you’re more likely to claim what you’re entitled to — rather than forgetting small but legitimate items that add up over the year.

What counts as “digital records”?

MTD is not just about sending information online. The core requirement is that certain details are kept digitally and submitted via MTD-compatible software.

In everyday terms, that usually means using cloud accounting software (or an app) to record:

• Income (sales/fees/rents received)
• Business expenses (costs you can claim)
• The dates and amounts

Some people currently use spreadsheets. In many cases, you can still use spreadsheets if they are linked to MTD-compatible software in the right way (often via “bridging” solutions). However, for most people, moving to a straightforward bookkeeping app is the least stressful route.

Do quarterly updates mean you have to pay tax quarterly?

This is one of the biggest worries we hear. Under MTD for ITSA, you will be sending quarterly updates, but that does not automatically mean you will pay Income Tax quarterly.

Payment rules can change over time, and HMRC has discussed longer-term ideas around more frequent payments. But the core 2026–2028 MTD for ITSA rollout is about reporting during the year. Most people will still be paying tax under the existing Self Assessment payment timetable unless and until HMRC changes payment dates separately.

What quarterly updates do mean is that you’ll have a more regular view of your likely tax position, which can help you set money aside steadily rather than relying on a last-minute calculation.

Will MTD mean you pay more tax?

MTD itself does not change tax rates. But it can affect how much tax you end up paying in practice because:

• Better records can reduce errors and missed expenses (often reducing tax compared to rough estimates).
• More visibility can prevent underpaying and then facing interest/penalties later.

If you’ve been under-reporting income by mistake (for example, missing cash sales or forgetting to include certain rents), MTD may make that harder to do unintentionally. The aim is accuracy — and accuracy cuts both ways.

What about landlords with one property or a small sideline?

MTD for ITSA is based on gross income from property and/or self-employment. That means even a “small” rental business can be brought in if rents exceed the thresholds, regardless of how hands-off it feels.

In practice, landlords often benefit from MTD-style bookkeeping because property expenses can be easy to miss unless you track them throughout the year — for example:

• Letting agent fees
• Repairs and maintenance (where allowable)
• Landlord insurance
• Safety certificates and compliance costs
• Replacement of domestic items (where relevant)

If you’re self-employed: what sort of costs should you be tracking?

The exact expenses depend on what you do, but the principle is the same: record costs regularly, keep evidence, and make sure you understand what’s allowable.

Common categories many self-employed people forget to track consistently include:

• Travel costs (business mileage or actual vehicle costs, depending on your method)
• Tools, equipment, and small consumables
• Mobile phone and data (business portion)
• Professional fees (accountancy, memberships, relevant subscriptions)
• Use of home as office (where applicable)

MTD nudges you towards capturing these little-and-often, which is usually where the real savings are.

What if you have more than one income source?

Many people have a mix: a small self-employed trade plus rental income, or two separate self-employed activities. Under MTD for ITSA, you may need to send quarterly updates for each relevant “business” and for property income.

This is where a good setup matters. With the right software and a sensible routine, it doesn’t have to be complicated — but without that, it can feel like you’re doing the same job multiple times.

What happens if you don’t comply?

HMRC is moving towards a points-based penalty system for late submissions in various areas of tax. The exact application and thresholds for MTD for ITSA will matter, but the practical message is:

• There will be more deadlines than once a year.
• Missing deadlines repeatedly is more likely to trigger penalties.
• Good processes (and reminders) become essential.

This isn’t about scaring you — it’s about being realistic. If you currently find the annual tax return deadline hard, you’ll want to set up a simple monthly habit now, so quarterly updates become routine rather than a crisis.

How to prepare for MTD for ITSA without overwhelm

Preparation doesn’t have to mean a big project. For most people, it’s a handful of sensible steps.

Step 1: Work out when you’re likely to be mandated

Look at your last tax return(s) and identify your gross income from:

• Self-employment turnover
• Property rents received

Then compare that to the thresholds for April 2026, April 2027, and April 2028.

Step 2: Choose a record-keeping method you can stick to

The “best” software is the one you’ll actually use. For many people, that means:

• Connecting your business bank account so transactions feed in automatically
• Using an app to capture receipts as you go
• Keeping categories simple and consistent

Step 3: Set a monthly bookkeeping slot

Quarterly updates are much easier if you’re already up to date monthly. Even 30–60 minutes a month can be enough for a straightforward business once the system is set up.

Step 4: Keep evidence tidy

Digital records are stronger when you can back them up. Save invoices and receipts, and where possible attach them to the transaction in your software.

Step 5: Get support early if you’re unsure

MTD is a compliance change. If you’re not confident about what counts as an allowable expense, or you’re not sure how your income sources fit together, it’s worth asking before you build a system around the wrong assumptions.

Common worries (and honest answers)

“This is just more admin for small businesses.”

Yes, it can be more frequent admin. But done properly, it’s often less total admin across the year because you avoid the annual panic. The key is a simple routine and the right tools.

“I’m not good with software.”

You don’t need to be “techy”. Most modern bookkeeping apps are designed for non-accountants. We also find that a short setup session and a clear monthly checklist makes a huge difference.

“I already use spreadsheets — do I have to change?”

Possibly. Some spreadsheet-based approaches can be adapted with bridging software, but many people find it easier (and safer) to use MTD-compatible bookkeeping software directly, especially with multiple quarterly deadlines.

“Will HMRC know more about me?”

HMRC will receive more regular updates, yes. The best way to look at this is: if your records are accurate and you’re claiming what you’re entitled to, regular reporting should reduce risk rather than increase it.

What if you’re a limited company?

This article focuses on MTD for Income Tax (ITSA), which affects individuals with self-employment and/or property income.

However, there is an important related change: from March 2026, companies will need to use commercial software to submit their CT600 (and associated computations) to HMRC. In other words, even though MTD for Corporation Tax isn’t mandated in 2026, the direction of travel is clearly towards digital filing and compatible software.

If you run a limited company and also have personal income from self-employment or property, you may end up dealing with both worlds — company compliance and MTD for ITSA personally — so it’s worth mapping this out early.

A simple example: how MTD can help you stay in control

Imagine you’re self-employed and your income fluctuates. Under the old approach, you might only find out your true profit after the year ends, when you finally total everything up. Under MTD, you’re updating through the year, so you can:

• Spot a slow quarter early and adjust spending
• See whether you can afford new equipment
• Set aside a realistic amount for tax each month

MTD doesn’t remove the need to understand your numbers — but it does encourage a rhythm that makes understanding them easier.

What to do now (even if 2026 feels ages away)

April 2026 will come round quickly, especially if you need to change habits. The calmest approach is:

1. Check your likely start date using your gross income figures.
2. Start keeping cleaner digital records now, even before it’s mandatory.
3. Trial software in a quiet period rather than during January rush.
4. Build a monthly routine so quarterly submissions are straightforward.

At Tax Digital, we’re specialists in Making Tax Digital and we’re here to keep this practical. The goal isn’t to turn you into a bookkeeper — it’s to make sure you stay compliant, claim what you’re entitled to, and feel in control.
