If you’ve been hearing whispers about Making Tax Digital (MTD) and panicking slightly about whether it applies to you, take a deep breath. You’re not alone. One of the trickiest parts is figuring out your qualifying income - the magic number that decides whether you need to start submitting tax updates digitally.
The good news? It’s not as scary as it sounds. Let’s break it down, in plain English.
So, what exactly is MTD for Income Tax?
MTD, short for Making Tax Digital, is a government initiative from HM Revenue & Customs. The idea is simple: move tax reporting online, make it more regular and (hopefully) less stressful than cramming everything into one frantic Self Assessment return at the end of the year.
If you’re eligible, MTD means:
- Keeping your records digitally
- Sending quarterly income updates to HMRC
- Submitting a final declaration annually
But here’s the catch - MTD only kicks in if your income passes a certain threshold and that’s where qualifying income comes into play.
What is qualifying income for MTD anyway?
Qualifying income is basically your total income from:
- Self-employment
- Property (UK or overseas rental income)
That’s it. Simple, right?
Now, here’s the stuff that doesn’t count:
- Your salary from a day job
- Dividends from investments
- Interest from savings
- Pension income
So, if you’re juggling a 9-to-5 with a small side hustle or a rental property, only your self-employment and rental income contribute to your qualifying income.
Why it matters
Qualifying income determines whether MTD applies to you. As of now:
- From April 2026 the threshold is £50,000
- From April 2027 the threshold drops to £30,000
Go over that number? You’ll need to start submitting your tax info digitally. Stay under? You’re still safe with your regular Self Assessment… for now.
How to calculate qualifying income
The key is that qualifying income is based on gross income, not profit. Yes, HMRC wants to know your total turnover before you subtract expenses.
For example:
• Freelance income: £35,000
• Rental income: £20,000
Total qualifying income = £55,000
Even if you spent £25,000 on business expenses, it’s still £55,000 for MTD purposes. Yep, sometimes the tax world feels a bit unfair.
What if you have multiple streams of income?
Add them all up. It doesn’t matter if it’s from a side hustle, freelance work or renting out a property, if the total crosses the threshold, MTD applies. Simple addition saves you from late-night panics.
Common myths busted
1. “It’s based on profit.”
Nope. Remember… gross income before expenses.
2. “My salary counts.”
Only self-employment and property income count. PAYE jobs? Not included.
3. “My side hustle is tiny, I’m fine.”
Check the numbers anyway especially once the threshold drops to £30k.
While MTD might feel like extra work, going digital can make life easier. No more last-minute receipt hunts, better visibility of your finances year-round and fewer surprises in January. Plus, once you’re set up, it’s smooth sailing.
Qualifying income for MTD is simply the sum of your self-employment and property income before expenses. If that figure passes HMRC’s threshold, MTD rules apply.
