Landlords and MTD: Why the £20,000 Threshold is Only the Beginning
- Jul 27

For many UK landlords, the words "Making Tax Digital" (MTD) have felt like a distant cloud on the horizon: something to worry about "later." But as we move closer to 2026, that cloud is arriving, and it is bringing a fundamental shift in how rental income is reported to HMRC.
If you are a landlord with a modest portfolio or even a single property, you might have looked at the initial £50,000 threshold and breathed a sigh of relief. However, the government’s phased rollout strategy means that the vast majority of unincorporated landlords will be swept into the digital net by 2028.
At Accountant Search, we are already helping hundreds of property owners transition away from messy spreadsheets and paper receipts. Here is why the £20,000 threshold is the real date you need to watch, and why digitising your property business today is the smartest move you can make.
The Three-Phase Rollout: Where Do You Sit?
The transition to MTD for Income Tax Self Assessment (ITSA) isn’t happening all at once. HMRC is using a tiered approach based on your "qualifying income": which is the combined gross income from your self-employment and property rentals.
April 2026: Landlords and sole traders with income over £50,000.
April 2027: Landlords and sole traders with income over £30,000.
April 2028: Landlords and sole traders with income over £20,000.
While the £50,000 group is the "early adopter" squad, the drop to £20,000 in 2028 represents a massive expansion. This threshold captures many part-time landlords, retirees with a rental property, and small-scale investors who previously only dealt with tax once a year.
Why the £20,000 Threshold is the "Real" Deadline
It is easy to look at the 2028 date and think you have plenty of time. But there is a hidden catch: the "test period."
HMRC determines if you fall into MTD based on your tax returns from previous years. For the April 2028 deadline (the £20,000 group), HMRC will likely look at your 2026-27 tax year data. This means the records you are keeping right now and over the next 18 months will dictate exactly when you are forced to switch to quarterly digital reporting.
Furthermore, the £20,000 threshold is significant because it signals the end of the traditional annual Self Assessment for almost everyone except those with the smallest supplemental incomes. If your rental income is your primary focus or even a significant side-hustle, you are almost certainly on the list.
The Hidden Trap: "Qualifying Income" vs. Profit
One of the most common misconceptions we hear at Accountant Search is landlords thinking they are safe because their profit is low.
MTD thresholds are based on gross income (turnover), not profit.
If you collect £22,000 in rent but pay £18,000 in mortgage interest, repairs, and management fees, your profit is only £4,000. However, for MTD purposes, you are a "£22,000 landlord." This means you will be legally required to follow MTD rules from April 2028, even if your actual take-home pay from the property is minimal.
Quarterly Reporting: The New Reality
Under MTD, the "once-a-year" tax scramble is dead. Instead, you will be required to:
Keep digital records of all income and expenses.
Submit quarterly updates to HMRC using MTD-compatible software.
Provide a Final Declaration by the end of the tax year.
This is a significant increase in administrative burden. If you are still using a shoebox for receipts or a manual ledger, the move to quarterly submissions will be a painful shock to the system if you wait until the last minute.

Why Waiting Until 2028 is a Mistake
We often advise our clients to start digitising at least one full tax year before they are mandated. Here is why:
1. Software Learning Curves
Learning to use platforms like Xero, QuickBooks, or Hammock takes time. You don't want to be learning how to categorise a boiler repair while simultaneously facing a hard HMRC deadline for your first quarterly update.
2. Real-Time Tax Visibility
Digital accounting gives you a "dashboard" view of your property business. Instead of wondering what your tax bill will be in January, you can see your estimated liability in real-time. This is essential for cash flow planning, especially with rising interest rates.
3. Finding the Right Help
As the 2026 and 2027 deadlines approach, the best accountants in the UK will be inundated with landlords looking for help. If you wait until 2028, you may find that local firms are at capacity. Starting now allows you to secure a partnership with an expert property accountant before the rush.
