No. As of September 2026, landlords do not pay National Insurance on rental income, and the Autumn Budget 2025 did not introduce it despite months of rumours. What it did instead was raise income tax on property income by 2 percentage points from April 2027, explicitly because rent escapes National Insurance. With a new Chancellor's first Budget due on 28 October 2026, the rumour is back, so here is where things actually stand, what a charge would cost, and what is worth doing about it.
Do landlords pay National Insurance on rental income?
Not in the normal case. Rental income is taxed as property income, not as trading profit, and the two main National Insurance charges on earnings do not reach it:
- Class 1 applies to employment income.
- Class 4 applies to trading profits: for 2026-27, 6% on profits between £12,570 and £50,270 and 2% above that (GOV.UK self-employed rates).
A standard buy-to-let is not a trade, so neither applies. The exception is letting that looks more like a hotel than a tenancy: where you provide substantial services, HMRC can treat the activity as a trade, and trading profits do attract Class 4.
What landlords can do is pay voluntary contributions to protect their State Pension record. GOV.UK's guidance on paying tax on rental income says you may be able to pay voluntary Class 2 if your letting counts as running a business, giving examples such as being a landlord as your main job, renting out more than one property, or buying new properties to rent out. If you do not qualify, voluntary Class 3 may be available instead. More on why that matters below.
Was National Insurance on rental income in the Autumn Budget 2025?
No. In August 2025 The Times reported that the Treasury was considering applying National Insurance to rental income, with reports suggesting the 8% employee rate and around £2 billion a year of revenue (Mortgage Solutions, 28 August 2025). The Budget on 26 November 2025 did not do it. Instead it announced, for 2027-28 onwards:
- Property income tax rates of 22%, 42% and 47%, up from 20%, 40% and 45%, from 6 April 2027.
- Section 24 mortgage interest relief given at the 22% property basic rate, not 20%.
- Personal allowances and reliefs applied to other income first, so property income sits at the top of your tax stack.
The government's own policy paper gives the reason in one sentence: "Those with property, savings or dividend income pay less tax than those whose income comes from employment or self-employment as they do not pay National Insurance" (GOV.UK policy paper). In other words, the 2-point rise is the Treasury's answer to the National Insurance gap. That does not rule out a second answer later, but it is the clearest sign of which tool it chose. Our guide to the 2027 property income tax changes covers the detail.
Could National Insurance on rental income come in at the October 2026 Budget?
Possible, but nothing points to it. Andy Burnham became Prime Minister on 20 July 2026 and appointed John Healey as Chancellor, and Healey will deliver his first Budget on Wednesday 28 October 2026 (GOV.UK). Burnham has said he sticks by Labour's 2024 manifesto, which rules out raising National Insurance, VAT and the basic, higher and additional rates of income tax on working people.
That pledge is about rates on working people, which is exactly why the rental income rumour will not die: extending National Insurance to landlords would arguably not break it. Trade press listed National Insurance on rental income among ideas reportedly under discussion in late July, and pre-Budget commentary still names "extending the scope" of National Insurance as a revenue option. No proposal has been published, and the Treasury does not confirm tax changes before a Budget.
Two things argue against it this year. The 2-point property rate rise is already legislated for April 2027, and stacking a new charge on the same group before the first one bites would be a hard sell. And the policy paper above treats the rate rise as the fix for the National Insurance gap. Treat it as a rumour until 28 October.
What would National Insurance on rental income cost a landlord?
It depends almost entirely on the design, and two designs have been floated in one form or another:
- Class 4 style: 6% on profits between £12,570 and £50,270, 2% above, as the self-employed pay now.
- Flat 8% from the first pound, as the 2025 reports suggested.
A third unknown is whether it would be charged before or after Section 24 finance costs. The table below uses profit before finance costs, the worse case for you, and compares each design with the 2-point rise that is actually legislated. The legislated column assumes finance costs of £5,000, £10,000 and £25,000 respectively and today's frozen thresholds.
| Landlord | Rental profit (before finance costs) | Legislated 2027 rise (real) | NI, Class 4 style (hypothetical) | NI, flat 8% (hypothetical) |
|---|---|---|---|---|
| A: £40,000 salary plus one let | £15,000 | £200 | £146 | £1,200 |
| B: rental income only | £40,000 | £349 | £1,646 | £3,200 |
| C: rental income only | £80,000 | £849 | £2,857 | £6,400 |
Three things jump out:
- Design matters more than the rate. A Class 4 style charge, with its £12,570 threshold applied to the rental profit itself, would barely touch a side-landlord like A. A flat 8% would cost A six times the legislated rise.
- Full-time landlords carry most of the risk. Landlord B faces a £349 rise that is certain, and a £1,646 to £3,200 charge that is not. That second number is the one to stress-test, not budget for.
- Scotland and Wales are no shelter. National Insurance is UK-wide, so a charge would apply wherever your property is. By contrast, Scottish and Welsh taxpayers' property income rates are due to be set by the devolved governments, while the 22% finance cost relief applies across the UK.
Run your own profit before and after finance costs in the rental income tax calculator, and see Section 24 explained for how the finance cost credit works.
Would a limited company avoid it?
Under any design that mirrors existing rules, probably yes. Companies pay corporation tax on profits, not National Insurance, and dividends carry no National Insurance (though dividend tax rates rose to 10.75% and 35.75% from April 2026). That makes incorporation the obvious escape route, which is also why it is a poor reason to act now. Moving an existing portfolio into a company usually triggers stamp duty and capital gains tax on the transfer, and those bills are certain while the National Insurance charge is not. See the cost of incorporating a buy-to-let portfolio or compare the two structures in the limited company vs personal calculator.
Can landlords pay National Insurance voluntarily?
Yes, and for some it is one of the cheapest wins available. Class 2 for 2026-27 is £3.65 a week, or £189.80 for the year (GOV.UK), and a year of contributions counts as a qualifying year towards the State Pension. If you are a full-time landlord with no employment income, you may have gaps in your National Insurance record that Class 2 could fill at a fraction of the Class 3 price.
Eligibility is HMRC's call, based on whether your letting amounts to a business, so check your State Pension forecast first and ask HMRC or your accountant before paying.
What should landlords do before 28 October?
- Nothing structural on a rumour. Do not incorporate, sell or restructure because of a charge that has not been announced.
- Know your two profit figures. Profit before and after finance costs, per property, so you can price any announcement in minutes.
- Plan for the certain change. The 22%, 42% and 47% rates start on 6 April 2027 whatever happens on Budget day.
- Check your State Pension record if you are a full-time landlord, and consider voluntary Class 2 if you qualify.
- Read the Budget documents on the day. A real measure comes with legislation and a start date. Anything without one is still a rumour.
