Autumn Budget rumblings: could rental income face National Insurance contributions?

1 Sep 2025

There’s growing speculation that the UK government may extend National Insurance (NI) contributions to rental income, a move that could reshape the tax landscape for landlords and property investors once again.

Sources suggest an NI levy on rental profits is under consideration as part of efforts to address a significant fiscal gap. While this wouldn’t breach Labour’s pledge not to raise NI rates, it would broaden the scope of NI to include “unearned income.”

Implications:

  • Potential increase in landlord costs
  • Pressure on rental supply and affordability
  • Greater alignment between tax treatment of earned vs unearned income

All eyes are on the Autumn Budget for confirmation. If implemented, this could mark a pivotal shift in property taxation.
