If you own two or three rental properties, you might assume Making Tax Digital means it's finally time to hire an accountant. For many landlords, it isn't. With a little routine and the right software, handling your own quarterly updates is genuinely manageable — even across a small portfolio.
Let's walk through how it actually works.
First, check whether (and when) MTD applies to you
Making Tax Digital for Income Tax is being phased in by your qualifying income — that's your gross rental income plus any self-employment income, before you deduct expenses. It's turnover, not profit, which catches a lot of people out.
The dates are:
- Over £50,000: from 6 April 2026
- Over £30,000: from 6 April 2027
- Over £20,000: from 6 April 2028
If your qualifying income is under £20,000, you're not required to join yet. You can read the official rules on the MTD for Income Tax guidance on GOV.UK, and we've broken the numbers down further in our guide to MTD income thresholds.
The key point for small portfolios: it's your total gross rent across all your properties that counts, not each property separately. Three flats bringing in £18,000, £16,000 and £14,000 add up to £48,000 — which puts you in scope from April 2027.
What you'll actually have to do
Once you're in MTD, three things replace your old Self Assessment return for that income:
- Keep digital records of your income and expenses.
- Send HMRC four quarterly updates per tax year.
- Submit one final declaration after the tax year ends.
The quarterly periods end on 5 July, 5 October, 5 January and 5 April, with deadlines of 7 August, 7 November, 7 February and 7 May. The final declaration is due by 31 January following the end of the tax year — the same date Self Assessment always used. There's more detail in our MTD deadlines guide.
Here's the reassuring part for multi-property landlords: you don't file four updates per property. Your property income is treated as a single UK property business. So three properties still mean four updates a year in total — not twelve.
A worked example across three properties
Let's say you're Tom, with three properties let out for the full year. From 2025-26 onwards, quarterly updates are cumulative — each one shows your year-to-date totals, not just that quarter in isolation.
For the first quarter (6 April to 5 July), you tot up across all three:
- Property A rent: £3,300
- Property B rent: £2,850
- Property C rent: £2,400
- Total income to date: £8,550
Allowable expenses in the same period — say letting agent fees, a boiler repair and landlord insurance:
- Agent fees: £960
- Boiler repair: £420
- Insurance: £310
- Total expenses to date: £1,690
So your first quarterly update reports £8,550 income and £1,690 expenses.
When the second quarter comes around (covering up to 5 October), you don't start from zero. You report the running totals for the whole year so far. If the second quarter added £8,550 of rent and £700 of expenses, your update would show £17,100 income and £2,390 expenses year-to-date.
Because it's cumulative, a small mistake in an earlier quarter quietly corrects itself in the next one — you're simply restating the up-to-date picture each time. That takes a lot of the fear out of getting it perfectly right first time.
Keeping it simple with a small portfolio
The trick with two or three properties isn't accounting wizardry — it's tidy habits.
Tag everything to the right property. You report a combined total to HMRC, but you'll want to know which property a £420 repair belonged to for your own records and decisions. Good software lets you label each transaction by property.
Do a little every month. Reconciling rent and logging expenses monthly means each quarterly update is a five-minute review rather than a frantic catch-up. Our guide on reporting property income to HMRC goes deeper on what to record.
Mind jointly-owned properties. If you own a property with a spouse or partner, each of you reports your share of the income and expenses, and the £20,000–£50,000 threshold is measured per person. So a couple jointly earning £60,000 gross rent might each be at £30,000 — which changes when each of you joins.
Do you need an accountant?
Honestly? Many small landlords won't. If your affairs are straightforward — a few residential lets, standard allowable expenses, no complicated structures — the quarterly updates are largely a matter of keeping records current and pressing submit.
That said, there's no shame in getting help. If you've got mixed income, a limited company, or you'd just rather have a professional cast an eye over things, you can absolutely use software alongside an accountant — see using MTD software with an accountant.
This is exactly the gap Quarterwise was built for: light bookkeeping that keeps your digital records, tags income and expenses by property, and files your quarterly updates and final declaration straight to HMRC. Built for landlords, not accountants.
With a steady routine, two or three properties is well within reach of doing yourself.
This is general information, not tax advice. Always check your own position with HMRC or a qualified accountant.
