Possible New Tax Burden for Landlords
Landlords could soon face another financial setback, with reports suggesting the Treasury is considering applying National Insurance (NI) charges to rental income for the first time. At present, rental profits sit outside the traditional income tax, NI, and VAT framework, but Chancellor Rachel Reeves may see landlords as an attractive target for raising revenue.
While no official details have been released, the idea appears to be exploratory. Rather than applying the standard NI rates of 8% on income up to £50,270 and 2% thereafter, the expectation is that a lower flat surcharge—perhaps between 1% and 3%—would be introduced, in a way similar to the stamp duty surcharge on second homes.
The Treasury has not confirmed the proposal, sticking to its usual position that tax changes will only be revealed at a Budget, expected in the autumn.
Echoes of Osborne’s 2017 Reforms
This potential move recalls the sweeping tax reforms brought in by George Osborne in 2017, which included stripping back mortgage interest relief and other landlord advantages. The sector has since faced rising costs, tighter regulation, and significant pressure from interest rate hikes.
Shaun Moore of Quilter warned that an NI levy would intensify these challenges:
- It could make small-scale landlords unprofitable.
- Landlords leaving the sector could drive rents up further.
- Ultimately, the burden would likely fall on tenants.
Ease of Implementation
One reason this measure might appeal to the government is practicality. Rental income is already reported on annual self-assessment tax returns, and with Making Tax Digital due to take effect from April 2026, landlords earning over £50,000 will be filing quarterly updates as well. This gives HMRC a streamlined way to track and collect any new NI charges.
The Treasury is reportedly seeking to plug a £50bn budget shortfall, and NI on property income is being floated as a way to raise around £2bn. It remains unclear, however, whether this figure applies annually or over the life of the current parliament.
Calls for Alternative Approaches
Some argue there are better ways to reform landlord taxation without adding another levy. Revisiting mortgage interest relief, for example, could balance fairness with revenue-raising. Allowing landlords to deduct interest before applying income tax—and even NI—might ease the pressure while still delivering funds to the Treasury.
Tax expert Andrew Park of Price Bailey also highlighted a key inconsistency: rental income has never been treated like employment income, which means landlords don’t gain state pension credits or pension contribution allowances from it. If the government starts treating rental income as “earned,” Park suggests it should also come with the same pension benefits—otherwise, it risks being seen as an unfair cash grab.
Wider Context
This proposal comes on top of other potential property tax changes, including removing capital gains tax relief on high-value homes and revising stamp duty thresholds. For landlords and homeowners, especially in London and the South East, these shifts could add significant pressure.
James Quarmby of Stephenson Harwood warned that despite assurances after the last Budget that the worst was over, the next one “could prove even harsher.”
