Rental expenses under NRLS and Self Assessment
Why the withholding calculation and the final property-business result may differ.
Direct answer
An agent operating NRLS deducts tax after certain expenses it has paid, but that withholding calculation is unlikely to equal the landlord’s final liability. The annual property schedule performs the broader tax reconciliation.
Working route
Collect the full property ledger
Keep rent, agent statements, repairs, insurance, professional fees, finance records and periods of personal use.
Keep withholding evidence
The annual certificate shows tax already deducted and is separate from the expense ledger.
Distinguish repairs from capital work
Improvements and acquisition costs should not be treated automatically as current rental expenses.
Hard stop
Finance-cost restrictions, mixed use, furnished holiday treatment, capital improvements and company ownership need tailored treatment.
