The 5 Biggest Lies You've Been Told About Making Tax Digital for Income Tax
If you are a sole trader or a landlord in the UK, the acronym "MTD" has likely been floating around your inbox for years. Making Tax Digital (MTD) for Income Tax Self-Assessment (ITSA) has been delayed, debated, and redesigned so many times that it’s easy to dismiss it as "the tax change that never happens."
However, the rollout has now started. Since 6 April 2026, the biggest shake-up to the UK tax system in a generation has begun phasing in for hundreds of thousands of business owners, with further income thresholds following in 2027 and 2028.
Because of the constant changes, a lot of misinformation has filled the void. As an SME owner, following the wrong advice could lead to more than just a headache: it could lead to HMRC penalties and significant financial stress.
At Accountant Search, we believe in keeping things simple. Today, we’re debunking the five biggest lies you’ve been told about Making Tax Digital for Income Tax, so you can stop worrying and start preparing.
Lie 1: "It’s Just Another New Tax"
One of the most common misconceptions is that MTD is a "stealth tax" designed to take more money from small businesses.
The Truth: MTD is not a tax; it is a reporting change.
The actual rules for how your tax is calculated: your personal allowance, your tax bands, and the expenses you can claim: remain exactly the same. What is changing is how and when you report that information to HMRC.
Instead of filing one big Self-Assessment return once a year, you will move to a digital system that requires more frequent touchpoints. The goal is to reduce manual errors (which HMRC estimates cost the UK billions in lost revenue) and give you a more real-time view of what you owe.
Lie 2: "Excel Is Enough to Be Compliant"
Many business owners have spent years perfecting their custom Excel spreadsheets. If you’re comfortable with formulas and macros, you might think you’re already "digital."
The Truth: While you can still use Excel, it is no longer a standalone solution for MTD.
Under the new rules, your records must be "digitally linked." This means you cannot simply type your totals into the HMRC portal at the end of the year. You must use HMRC-recognised software that can talk directly to HMRC’s systems.
If you insist on staying with spreadsheets, you will need to invest in "bridging software" that extracts the data from your Excel file and submits it to HMRC. However, for most SMEs, switching to a dedicated accounting package like Xero or QuickBooks is often more efficient than trying to "hack" a spreadsheet to be compliant.

Lie 3: "HMRC Will Do the Heavy Lifting for Me"
There’s a dangerous myth that because the system is "digital," HMRC’s computers will automatically calculate everything correctly once you connect your bank account.
The Truth: The responsibility for accuracy lies entirely with you.
While MTD-compatible software can automate things like bank feeds, it doesn't know the difference between a personal lunch and a business expense. You still need to categorise transactions correctly, ensure you’re claiming the right reliefs, and verify that your digital records match reality.
HMRC is providing the "pipes" for the data to flow through, but you (and your accountant) are still the ones who have to turn the tap. If you assume the system will manage itself, you’ll likely find yourself in a mess of uncategorised transactions and missed deadlines.
Lie 4: "It Only Affects the Big Players"
Because the initial rollout of MTD focused on VAT-registered businesses with high turnovers, many small sole traders and landlords believe they are "too small" to be included.
The Truth: The 2026, 2027 and 2028 thresholds will bring in millions of small businesses.
Here are the hard facts for the rollout:
- April 2026: If you have an annual business or property income over £50,000, you must join.
- April 2027: If your income is over £30,000, you must join.
- April 2028: If your income is over £20,000, you must join.
Crucially, this is based on gross income (turnover), not profit. If you are a landlord receiving £2,600 a month in rent, you are already over the £30,000 threshold, even if your mortgage and maintenance costs mean you’re barely breaking even.
Lie 5: "I Have Plenty of Time to Prepare"
The first phase is already live, and the next thresholds are approaching quickly.
The Truth: Preparation should start now.
The transition to MTD involves three major hurdles:
- Software Selection: Finding the right tool that fits your business.
- Digital Cleanup: Moving your old paper or basic spreadsheet records into a digital format.
- Quarterly Habit: Adjusting to the new rhythm of submitting four quarterly updates, plus a year-end "Final Declaration."
If you leave it too late to find an accountant or choose software, you’ll be competing with every other business owner trying to get ready at the same time. Prices for accounting services can rise, and the best-matched firms may already be at full capacity.
