For most of us, tax has been a once-a-year job. A folder of receipts in January, a return, done. That is ending. The scheme is called Making Tax Digital for Income Tax, and if you hold rental property in your own name it is either already your problem or about to be.
Here is the plain version. Since 6 April this year, landlords and sole traders with more than £50,000 of qualifying income have had to keep digital records and send HMRC a summary of income and expenses every quarter, through software that connects to HMRC. The first update was due on 7 August. The second quarter closes on Monday 5 October, and that update is due by 7 November.
If that is you and you are behind, do not panic, but do not drift either. HMRC has said it will not apply penalty points for late quarterly updates in this first year. The catch is that the updates still have to go in before you can file your tax return, and the return itself is not let off. After this tax year, each missed quarterly deadline earns a point. Four points is a £200 penalty, and another £200 for each deadline missed after that. This year is the practice run. Use it.
Now the part that catches the smaller landlord. From 6 April 2027 the line drops to £30,000, and from April 2028 to £20,000. Four things trip people up.
It is income before expenses, not profit. £30,000 of rent coming in counts, even if the mortgage, the repairs and the agent leave you with a fraction of it.
Rent and self-employment are added together. A couple of rentals plus a sole trader sideline is one combined figure as far as HMRC is concerned.
The test year has already finished. Whether you are in from April 2027 is decided by your 2025 to 2026 tax return, the one due by 31 January. Those numbers are fixed now. All you can do is check them.
Joint owners count their own share. If two of you own equally and the property brings in £50,000, that is £25,000 each. On the same rents, you are under the line for 2027 and over it for 2028.
One exclusion worth knowing. This is an income tax scheme. If your properties sit in a limited company, the company is not caught by it.
So here is how I would get ready, whichever side of the line you are on.
Add up your gross rents for the year to 5 April 2026 this week. HMRC says it will write to the people it thinks are caught, but it also says you must check for yourself even if no letter arrives.
Choose your software before you need it. Ask your accountant which packages they work with, because a spreadsheet on its own will not send anything to HMRC.
Run the rentals through one bank account. Software that reads a clean bank feed does most of the work for you. Rent mixed in with the weekly shop does not.
Capture every receipt the day it arrives. A photo on your phone, straight into the records. Not a carrier bag in January.
Reconcile monthly. Twenty minutes a month turns the quarterly update into a button press. Leave it for three months and it becomes a lost weekend.
From my own portfolio: the habit that takes the fear out of all this is one I already run. Every invoice and receipt goes into a capture app the day it lands, and from there it flows to my accountant. Nothing waits for year end. I did not set that up for HMRC. I set it up because hunting for an invoice months after the job was done is a miserable way to spend an evening. It turns out the same habit is exactly what quarterly reporting needs. The landlords who will find this painful are not the ones with complicated affairs. They are the ones whose records only exist in January.
The temptation is to look at £30,000 and think it is a problem for bigger landlords. I would not. In much of the country that is two or three ordinary lets, and the year that decides it is already behind you.
The takeaway: tax for landlords is moving from once a year to four times a year. Over £50,000 of gross rent and self-employment income, you are already in, and your next update is due by 7 November. Over £30,000, you join in April 2027, and it is last year's figures that decide. It is gross income that counts, not profit. Add up your number, pick your software, and start keeping records as you go.
I am a landlord, not your tax adviser, so check your own position with your accountant. And if you know a landlord who still does their books in one go every January, send them this. For a lot of us, that way of working has about six months left.
