"Is there a new property tax coming in 2027, and do I need to do something now?" That is the question turning up in landlord forums most weeks. The honest answer is reassuring and annoying in equal measure: the one change already written into law for April 2027 is not a new tax at all. It is a new way of reporting the tax you already pay. Most of the scarier "2027" headlines are speculation dressed up as fact. Here is how to tell the two apart so you plan for what is real and ignore the noise.
The confirmed change: Making Tax Digital from April 2027
The genuinely legislated 2027 change is Making Tax Digital for Income Tax, usually shortened to MTD for ITSA. It was confirmed at the Autumn Budget on 30 October 2024 and is being phased in by income level (gov.uk guidance):
- From April 2026: sole traders and landlords with gross self-employment and property income over £50,000 (already live).
- From April 2027: those with gross income over £30,000.
- From April 2028: those with gross income over £20,000.
If you are caught, the annual Self Assessment return you file each January is replaced by a quarterly rhythm. You keep digital records in compatible software, send HMRC four cumulative updates a year, then confirm the full picture with a final declaration after the tax year ends. Late quarterly updates carry a points-based penalty system, so this is not a filing you can casually skip.
None of that changes the tax you owe. Your rates, allowances and reliefs are unaffected by MTD itself. What changes is the admin: more frequent, more digital, less "shoebox of receipts in January".
The trap: it keys off gross rent, not profit
The single most misread part of MTD is the threshold. It looks at your gross self-employment and property income combined, before a single expense comes off. Mortgage interest, letting fees, insurance and repairs do not reduce the number that decides whether you are in.
That matters enormously for buy-to-let, where finance costs can be large and profit thin. A landlord making almost no profit can still be pulled into quarterly filing purely on turnover.
Worked example: does £30,000 catch you?
Take a landlord with two modest properties:
| Property | Monthly rent | Annual gross rent |
|---|---|---|
| Flat A | £950 | £11,400 |
| House B | £1,600 | £19,200 |
| Total gross | £30,600 |
That £30,600 sits just over the £30,000 line, so this landlord joins MTD from April 2027, even though their actual taxable profit is far lower. After mortgage costs and running expenses their real profit might be somewhere around £8,000 to £12,000 (a figure that will vary hugely with their loan and is only illustrative here). The tax bill follows the profit; the filing obligation follows the £30,600.
Two practical consequences fall out of this. First, a single rent increase or an extra room let can tip you over the threshold a year early, so check the running total, not last year's number. Second, if you also have side self-employment income, it counts towards the same total.
What is only proposed or rumoured
This is where over-reacting costs landlords money. Several "2027" claims are not law, and some are not even formal proposals. Treat the following as unconfirmed until a Budget says otherwise:
- National Insurance on rental income. Applying NICs to property profits gets floated in the press before most fiscal events. As things stand, rental profit is not treated as a trade and does not attract Class 4 NIC. There is no legislation to change that. It is a recurring rumour, not a plan.
- A fresh squeeze on mortgage-interest relief. Section 24 already restricts relief for individual landlords to a 20% basic-rate tax credit, with companies still deducting interest in full. That regime is fully in force and no further cut has been announced for 2027.
- Higher Capital Gains Tax on property. Residential CGT is currently 18% at the basic rate and 24% at the higher rate (gov.uk rates). Rates are reviewed at fiscal events, so change is always possible, but nothing specific is confirmed for 2027.
The pattern is worth internalising: a policy is real once it is in an Act or a published Finance Bill measure with a commencement date. Everything before that is a signal to stay flexible, not to restructure your portfolio in a panic.
Confirmed, but not a tax: deadlines to plan around anyway
Two changes near 2027 are not property-income taxes but will shape your cashflow and are worth mapping onto the same timeline:
- EPC minimum standards. A minimum EPC band C is proposed for new tenancies by 2028 and all tenancies by 2030. Retrofit spending is a capital and cashflow question you may want to phase before the tax-admin workload of MTD lands.
- The Renters' Rights Act 2025. It received Royal Assent on 27 October 2025, the main reforms commenced on 1 May 2026, and all tenancies are now periodic. Pre-1-May-2026 Section 21 notices remain enforceable in court only until 31 July 2026. This affects how you manage tenancies, not how rental profit is taxed, but it belongs on your planning calendar.
What to actually do before April 2027
You do not need to act today, but a few unhurried steps now save a scramble later:
- Work out your gross figure. Add up all property rents plus any self-employment income, before expenses. If you are near £30,000, assume April 2027 applies and plan for it.
- Get your records digital early. Bank feeds and simple bookkeeping software make the quarterly cadence routine rather than painful. A portfolio tracker that already holds your rents and expenses does most of the heavy lifting.
- Talk to your accountant about pricing. Quarterly filing may change what they charge. Ask now, not next spring.
- Separate fact from rumour when you read the next Budget. File anything without a commencement date under "watch", not "act".
The takeaway for property income tax in 2027 is calmer than the headlines suggest. One real change (digital, quarterly reporting for those over £30,000 gross), a handful of persistent rumours worth ignoring until confirmed, and two non-tax deadlines to keep in view. Prepare for the confirmed item, stay adaptable on the rest, and you avoid both the fine and the overreaction.
This is general information, not tax or financial advice. Rates and rules change at fiscal events, so check the current gov.uk figures or speak to a qualified adviser about your own position.
