Making Tax Digital is rolling out across the UK, and there's dangerous misinformation everywhere.
If you're running a marketing agency, chances are MTD already affects you through VAT requirements. And with Income Tax changes hitting businesses earning over £50,000 from April 2026, most agencies will be caught in the next wave.
The problem? Agency owners are making costly assumptions about what MTD actually requires.
Here are the eight biggest myths we're seeing and the reality behind each one.
Myth 1: "MTD Means Going 100% Digital"
Reality: You don't need to eliminate paper entirely.
MTD requires digital record-keeping, not a paperless office. You can still receive paper receipts or invoices. You just need to get the data into your accounting software quickly.
The key is having a system. Use apps like Dext to photograph receipts instantly, or ensure your accounting software generates invoices digitally so the data's already captured.
Myth 2: "HMRC Will See All My Financial Data"
Reality: HMRC isn't asking for more data than before.
For VAT, you're still submitting the same nine boxes of information. For Income Tax, MTD requires quarterly updates, but these don't need to be perfectly accurate because they're progress reports, not final submissions.
The real benefit? You'll have a clearer picture of your tax position throughout the year, not just at year-end.
Myth 3: "MTD Will Increase My Tax Bill"
Reality: MTD doesn't change what you owe, just how you report it.
If you've been calculating taxes correctly, MTD won't cost you more. It's designed to reduce errors and fraud across the system, not extract additional revenue from compliant businesses.
Think of it as upgrading from a calculator to a computer. Basically a different tool, same math.
Myth 4: "My Accountant Handles MTD for Me"
Reality: You still need to maintain digital records yourself.
Even with an accountant, you must keep your records digitally. This catches out many agency owners who assume their accountant's involvement means they're exempt from MTD requirements.
Your accountant can prepare reports, but the day-to-day digital record-keeping responsibility remains yours.
Myth 5: "Voluntary VAT Registration Exempts Me"
Reality: All VAT-registered businesses must comply.
This changed after April 2019. Whether you registered for VAT by choice or because you exceeded the threshold, MTD for VAT applies to every VAT-registered business.
No exceptions based on how or why you registered.
Myth 6: "MTD Only Affects 'Real' Businesses"
Reality: Side hustles and rental income count too.
That property you rent out? If it generates over £50,000 annually, MTD for Income Tax applies from April 2026.
Freelance work alongside your agency? If combined income exceeds the thresholds, you're in scope.
HMRC's definition of "business" is broader than many people assume.
Myth 7: "No More Tax Returns Under MTD"
Reality: Returns are replaced, not eliminated.
MTD for VAT still requires VAT returns, but this time, submitted digitally through software.
MTD for Income Tax replaces Self Assessment with a "final declaration," but you're still crystallising your annual position and calculating what you owe.
Myth 8: "Small Agencies Don't Need to Worry"
Reality: Size matters, but less than you think.
MTD for VAT affects any VAT-registered business regardless of turnover. A startup agency hitting £90,000 turnover faces the same requirements as a £5M agency.
For Income Tax, thresholds are:
- April 2026: £50,000+ income
- April 2027: £30,000+ income
- April 2028: £20,000+ income
Most scaling agencies will be caught in these waves.
Making Tax Digital
Ignorance is expensive. The agencies that get ahead of these changes (implementing proper systems and understanding the real requirements) will find compliance straightforward.
Those clinging to myths and old processes will face unnecessary stress, potential penalties, and administrative headaches that could have been easily avoided.
The transition is happening whether you're ready or not.
The question is: will you be prepared, or will you be scrambling to catch up?
Questions agency owners ask
