Can I opt out of Making Tax Digital?

No. If your self-employed or rental income exceeds the threshold (£50,000 from April 2026, £30,000 from April 2027), MTD is mandatory. There is no opt-out. You can apply for an exemption only if you have a genuine disability, religious objection to using computers, or live in an area with no internet access. These exemptions are very rarely granted.

What are the penalties for not doing Making Tax Digital?

HMRC uses a points-based penalty system. Each late quarterly submission earns one penalty point. Once you accumulate 4 points, you receive a £200 fine, and each subsequent late submission also triggers a £200 penalty. Late payment penalties are separate: 2% of unpaid tax after 16 days, another 2% after 30 days, then 10% per year accruing daily. Interest applies from day 1 at the Bank of England base rate plus 2.5%. However, HMRC has confirmed no penalty points for late quarterly submissions during the first year (2026/27).

What happens if I just continue filing Self Assessment normally?

If you're mandated for MTD, you must use MTD-compatible software for quarterly updates AND still file your annual Self Assessment return. Simply continuing with your old method means you'll fail to meet the quarterly reporting requirement. During 2026/27, the grace period means no penalty points for this, but from 2027/28, you'll start accumulating points and fines.

Will HMRC really enforce Making Tax Digital?

Yes. HMRC has invested heavily in MTD infrastructure since 2015 and has been sending notification letters to affected taxpayers since February 2026. Unlike previous postponements, this time the legislation is in place, the software ecosystem exists, and HMRC has publicly committed to the April 2026 start date. All major accounting software providers now support MTD.

What Happens If You Ignore Making Tax Digital? The Honest Answer

Let's be direct: you're here because you've heard about Making Tax Digital, you don't want to deal with it, and you're wondering what actually happens if you just... don't. You're not alone — a TechRadar report this week found that one in five self-employed workers haven't taken any steps to prepare. Here's the no-nonsense truth about what HMRC can and will do.

The Short Answer

If you ignore Making Tax Digital and you're required to comply, eventually you'll accumulate penalty points, receive fines, and pay interest on any late tax payments. But — and this is the crucial bit — HMRC has confirmed there are no penalty points for late quarterly submissions during your entire first year (2026/27).

That means you have a window. Not a window to ignore it forever, but a window to get sorted without panicking about fines.

Here's the timeline of what happens:

When	What Happens If You Do Nothing
6 April 2026	MTD becomes mandatory. You should start keeping digital records and submitting quarterly updates.
April 2026 – April 2027	Grace period. No penalty points for late quarterly submissions. But late payment penalties still apply to any tax you owe.
April 2027 onwards	Full penalty regime kicks in. Each late quarterly submission = 1 penalty point. 4 points = £200 fine.
Ongoing	Late payments attract 2% penalties at 16 days, further 2% at 30 days, then 10%/year accruing daily. Interest from day 1.

Who Actually Has to Comply

Before you panic, check whether MTD even applies to you. It's not everyone:

Start Date	Who's Affected	Income Threshold
6 April 2026	Self-employed individuals and landlords	Combined self-employed + rental income over £50,000
6 April 2027	Self-employed individuals and landlords	Combined income over £30,000
6 April 2028	Self-employed individuals and landlords	Combined income over £20,000

Not affected (yet):

Limited companies — MTD for Corporation Tax hasn't been announced
Employed people with no self-employment or rental income
Self-employed people under the relevant threshold
People who only receive pension income

The threshold is based on your gross self-employed and/or rental income — that's turnover, not profit. So if you invoice £55,000 but your profit after expenses is £35,000, you're still caught by the £50,000 threshold from April 2026.

What Actually Changes Under MTD

The fear around MTD is often worse than the reality. Here's what you actually have to do differently:

What Stays the Same

You still file an annual Self Assessment tax return
You still pay tax by 31 January (and 31 July for payments on account)
You still claim the same expenses and allowances
Your tax calculation doesn't change

What's New

Digital records: You must keep your income and expense records in MTD-compatible software (not spreadsheets, not shoeboxes)
Quarterly updates: You submit a summary of income and expenses to HMRC every quarter through the software
End of Period Statement (EOPS): A year-end summary confirming your figures
Final Declaration: Replaces part of your Self Assessment, confirming everything for the tax year

If you're already using accounting software like FreeAgent, Xero, or QuickBooks, the quarterly updates are essentially automatic — the software submits them for you. The extra work is minimal.

If you're currently doing everything on paper or a basic spreadsheet, the transition is bigger. But it's a one-time setup cost, not an ongoing nightmare.

The 4 Scenarios If You Ignore It

Scenario 1: "I'll just keep filing Self Assessment as normal"

This is the most common plan. And for Year 1 (2026/27), you'll probably get away with it — the grace period means no penalty points for missing quarterly submissions.

But from Year 2 (2027/28), you'll start accumulating penalty points. Miss all four quarterly updates and you'll hit the 4-point threshold, triggering a £200 fine. Each subsequent late submission is another £200.

Your annual Self Assessment still needs filing regardless. Late filing of the annual return carries separate penalties (£100 immediate, escalating from there).

Scenario 2: "I'll reduce my income below the threshold"

Some people are considering legitimately restructuring to stay under £50,000 gross income. If your actual income is near the boundary, this might work — but artificially suppressing income to avoid MTD would be tax evasion, which is a criminal offence.

Be aware: the threshold drops to £30,000 in April 2027 and £20,000 in April 2028. You'd have to keep reducing.

Scenario 3: "I'll incorporate as a limited company"

MTD for Income Tax doesn't apply to limited companies (yet). Some sole traders are considering incorporating specifically to avoid MTD. This is legal, but it comes with significant costs and administrative burden:

Corporation Tax filings (annual)
Company accounts (annual, filed at Companies House)
Confirmation Statement (annual)
PAYE/payroll if you pay yourself a salary
Dividend paperwork
Your details on the public Companies House register
Accountant fees (typically £1,000-2,000/year for a small company)

For most sole traders earning £50,000-80,000, the cost and complexity of running a limited company significantly outweighs the hassle of MTD quarterly submissions. For a detailed comparison, see our sole trader vs limited company guide.

Scenario 4: "I'll just completely ignore it and hope for the best"

HMRC knows who you are. They have your Self Assessment history, your UTR number, and they've been sending letters since February 2026. Ignoring it won't make you invisible — it just means the penalties accumulate without you managing them.

The late payment penalties (separate from submission penalties) start accruing interest from day 1 of a missed payment. These add up quickly and there's no grace period for them.

Penalty Details: The Actual Numbers

Late Submission Penalties (Quarterly Updates)

Event	Consequence
Each late quarterly submission	1 penalty point (no immediate fine)
Accumulate 4 penalty points	£200 fine
Each further late submission after 4 points	£200 per submission
Submit on time for 24 months	Points reset to zero

Year 1 exception: No penalty points during 2026/27. You effectively get a free pass on quarterly submissions while you get set up.

Late Payment Penalties

How Late	Penalty
1-15 days late	No penalty (but interest accrues from day 1)
16-30 days late	2% of unpaid tax
31+ days late	Additional 2% of unpaid tax (4% total) PLUS 10% per year accruing daily

Interest Rate

Late payment interest runs from the due date at the Bank of England base rate + 2.5%. With the base rate currently at 4.5%, that's 7% per year on any unpaid tax.

Worked Example: What Ignoring MTD Actually Costs

Let's say you earn £60,000 self-employed and owe £5,000 in tax. You ignore MTD entirely for 2 years:

Item	Year 1 (2026/27)	Year 2 (2027/28)
Late submission penalty points	0 (grace period)	4 points → £200
Further late submissions	—	Up to £800 more (4 × £200)
Late payment penalty (if tax 31+ days late)	£200 (4% of £5,000)	£200
Daily penalty (10%/year on £5,000)	~£500	~£500
Interest (7% on £5,000)	~£350	~£350
Total extra cost	~£1,050	~£2,050

Over two years, ignoring MTD could cost you around £3,100 in entirely avoidable penalties and interest — on top of the tax you already owe. That's money straight out of your pocket for no reason.

The Grace Period Nobody Talks About

Here's the most important thing in this entire article, and most coverage buries it or skips it entirely:

🛡️ HMRC has confirmed: NO penalty points will be issued for late quarterly submissions during the entire 2026/27 tax year.

This means if you're mandated from April 2026, you have a full 12 months to get set up without risking submission fines. Your first four quarterly updates are essentially penalty-free.

This doesn't mean you should do nothing — late payment penalties still apply from day 1. But it means the sky isn't falling. You have time to choose software, learn how it works, and get into the quarterly rhythm without HMRC penalising your submissions.

Think of 2026/27 as a practice year. Get your records digital, submit your quarterly updates (even if they're a bit late), and by April 2027 when the real penalty regime begins, you'll be comfortable with the process.

We've written a detailed breakdown of what the grace period does and doesn't cover: MTD Penalty Grace Period Explained.

Legitimate Ways to Be Exempt

HMRC does allow exemptions, but they're narrow:

Digital exclusion: You have a disability, age, remoteness, or religious objection that makes it unreasonable to use digital tools. You must apply for this — it's not automatic.
No internet access: You live somewhere with genuinely no broadband or mobile internet coverage.
Income below threshold: If your self-employed and rental income is below £50,000 (2026) / £30,000 (2027) / £20,000 (2028), you don't need to comply yet.
Insolvency: You're subject to an insolvency procedure.

"I don't want to" or "I find technology difficult" are not exemption grounds. HMRC expects most people to either use the software themselves or have an accountant/bookkeeper do it for them.

The Minimum-Effort Compliance Path

If you want to comply with the absolute least effort, here's what to do:

Choose the simplest free MTD software. HMRC has a list of compatible software, and some providers offer free tiers for basic sole traders. You don't need fancy features — you need something that submits quarterly updates.
Set up your records. Enter your opening balances and start recording income and expenses in the software. This takes 1-2 hours initially.
Submit quarterly. Every three months, review your records and click "submit" in the software. For simple businesses, this takes 15-30 minutes per quarter.
File your annual return as normal. The end-of-year process integrates with your Self Assessment.

Total ongoing time: roughly 2 hours per year for the quarterly submissions themselves, plus the time you'd normally spend on bookkeeping anyway.

The Bottom Line

Ignoring Making Tax Digital won't make it go away. HMRC has invested too much and come too far to back down now. But the penalties aren't as terrifying as the headlines suggest — especially with the Year 1 grace period giving you breathing room on quarterly submissions.

The pragmatic approach: use the grace period to get set up. Choose simple software, enter your records, and start submitting quarterly. It's an hour or two of setup and about 30 minutes per quarter after that. That's significantly less hassle than dealing with the penalties, interest, and stress of non-compliance.

The people who'll struggle most are the ones who leave it until April 2027 when the real penalties begin. Don't be that person. Start now — imperfectly — and refine as you go.
