The Withholding Mechanism
Once a landlord falls within NRLS and has not secured approval to receive rent gross, the collection duty passes to whoever is handling the property on the ground:
- Letting agents managing the property on the landlord's behalf must withhold tax from the rent before passing on the balance.
- Tenants take on this duty directly if there is no letting agent involved and the rent exceeds £100 a week.
The withholding rate is currently 20%, but this is due to change. From 6 April 2027, a new property basic rate of Income Tax comes into effect under separate legislation for property income, and NRLS withholding will follow that new rate, rising to 22%. Higher and additional rate property income also rises by 2 points, to 42% and 47% respectively. This affects England, Wales, and Northern Ireland; Scotland sets its own devolved rates and may or may not follow suit. There's no transition period, so letting agents and tenants will need to apply the new rate from the first quarter of the 2027/28 NRLS year.
The calculation itself differs depending on who is doing the withholding. Letting agents can deduct allowable expenses they've paid on the landlord's behalf, such as repairs or management fees, before applying the withholding rate to the remaining net rent. Tenants cannot do this: they calculate tax on the full rent paid to the landlord, and only exclude payments made directly to third parties where those payments are themselves deductible expenses. This means a tenant can't reduce the taxable amount by deducting expenses the way an agent can, and HMRC's guidance is explicit that tenants have no mechanism to reclaim tax for expenses they didn't get to offset. Either way, this is a simplified, in-year calculation and not the same as the landlord's own year-end figure. Whoever is withholding must register with HMRC and pay the amounts withheld over each quarter, on top of further reporting duties covered below. This is a legal obligation on the agent or tenant, not an optional courtesy to the landlord. For the wider set of costs a landlord can claim regardless of how rent is collected, our landlord tax guide covers what's deductible in full.
