National Insurance on Rental Income: What UK Landlords Need to Know in 2025

If you’re a UK landlord in 2025, you’ve likely felt the financial squeeze. Rising interest rates, 

stricter property regulations, and increased maintenance costs have made managing rental 

properties more challenging than ever. Now, there’s news that could shake the market further: 

National Insurance (NI) on rental income.

 

What’s Happening with Rental Income Tax?

Historically, landlords only paid income tax on rental profits, not National Insurance. NI applies 

to “earned” income like wages, not “unearned” income like rent.

The government is considering a change:

“If employees pay NI on their wages, landlords should pay NI on rental income.”

Although not confirmed, this could generate around £2 billion a year for the Treasury.

 

How Could This Affect UK Landlords?

•£30,000 rental profits → potentially £2,000+ extra tax per year

•£50,000–£70,000 rental profits → potentially £4,000–£5,000 extra tax

For some landlords, this is manageable. For others, it could force a rethink of their property portfolio.

 

Why This Matters for Landlords, Tenants, and Investors?

For landlords: Already thin profit margins may shrink further with higher National Insurance on 

rental income.

For tenants: Reduced rental supply could push up rent prices, making housing less affordable.

For investors: Shifting market conditions create opportunities. Savvy investors can secure Below
