The NRL Scheme for Letting Agents: Quarterly Returns, NRL6 Certificates, and Personal Liability

If you collect rent for a non-resident landlord, the duty to withhold basic-rate tax is yours, not the landlord's. The non-resident landlord (NRL) scheme puts it on the letting agent, and where no agent is appointed and the rent exceeds £100 a week, on the tenant. The rules sit in the Taxation of Income from Land (Non-residents) Regulations 1995 (SI 1995/2902), administered by HMRC's Non-Resident Landlord Centre, and the machinery you operate is the NRL2 quarterly return, the payment that goes with it, and the NRL6 annual certificate you give the landlord. The unforgiving piece is regulation 10: you are personally liable for tax that should have been withheld but was not, even tax on rent you have already paid away.

The questions that actually matter to you are different from the landlord's: how do you register, what goes on the NRL2, what counts as a deductible expense at the withholding stage, when does NRL1 approval to receive rent gross flip the calculation mid-quarter, and where does your personal liability begin? The basic-rate withholding is explained in full from the landlord's side elsewhere; here the focus is on computing and paying it. Two anonymised scenarios run through the page: Marlow Lets, an agent with 24 non-resident landlord properties, and Catherine, a tenant operating the scheme directly because her Hong Kong-based landlord has no agent.

Who is the duty-holder

The duty rests on the actual cash-flow path between rent payer and rent receiver, not on the contract description.

Letting agent. If you collect rent on behalf of a non-resident landlord, you are the duty-holder for that property. The test is operational: do you receive rent in the course of business and pay it on to the landlord (or into the landlord's bank account)? A managing agent does; a finder-only agent that introduces a tenant and walks away does not. Block managers handling service charges only are not duty-holders for rent. White-label arrangements where one agent administers and another brands do not change anything: whoever actually receives the rent holds the duty.

Tenant. Where no agent is appointed AND the rent exceeds £100 per week (equivalent to £5,200 a year), the tenant is the duty-holder. Below that threshold, the tenant has no withholding duty even where the landlord is non-resident. The threshold is per landlord per tenant, not cumulative across tenancies: a tenant paying £90 a week to a non-resident landlord has no NRL duty even if other tenants of the same landlord cross the threshold.

Landlord. The landlord is the chargeable person for income tax but is not the operational duty-holder. Their role is to apply for NRL1 approval to receive rent gross if eligible, and to file the annual UK self-assessment return reporting full UK rental income with credit for the tax you withheld at source.

Registering as an NRL agent

Before the first quarter in which you collect rent for a non-resident landlord, you must register with HMRC's Non-Resident Landlord Centre. Registration is by letter (currently to Charity, Assets and Residence, Trusts and Estates, BX9 1AS) giving:

• Your business name, trading address, and contact details.
• A list of the non-resident landlord clients you expect to serve, with each landlord's full name and UK rental property addresses.
• Your accounting period, so HMRC aligns the quarterly cadence.
• A nominated point of contact at the agency for NRL correspondence.

HMRC issues an NRL reference number, which you put on every subsequent NRL2 return and every tax payment. Registration is one-off. Deregistration requires written notification that all your non-resident landlord clients have been transferred away or that you have ceased the management business. Take on a new non-resident landlord client mid-year and you do not re-register: you simply update the existing client list on the next NRL2.

The quarterly cadence

The scheme runs on calendar quarters, not on your accounting year or the tax year.

• Quarter 1: 1 April to 30 June. NRL2 + payment due 30 July.
• Quarter 2: 1 July to 30 September. NRL2 + payment due 30 October.
• Quarter 3: 1 October to 31 December. NRL2 + payment due 30 January.
• Quarter 4: 1 January to 31 March. NRL2 + payment due 30 April.

The 30-day window is hard. Late filing attracts the standard automatic penalty (currently £100 fixed for the first month, then daily and tax-geared penalties for prolonged delay). Late payment attracts daily interest from the day after the due date plus a 5% surcharge at 6 months and another 5% at 12 months. The penalty framework mirrors the self-assessment regime. Miss a single quarter to a system migration or staff turnover and you can absorb the £100 and move on, but a pattern of late filing draws the personal-liability machinery into a more aggressive HMRC posture.

NRL2 line items: computing the withholding

The NRL2 is a single return covering all of your non-resident landlord clients for the quarter. For each landlord, it captures:

• Full name and HMRC reference (the landlord's UTR or the NRL approval reference if NRL1-approved).
• Total gross rent collected in the quarter.
• Total deductible expenses paid in the quarter against that landlord's properties.
• The net withholdable amount (gross minus deductible).
• The 20% basic-rate tax computed on the net withholdable.
• Cumulative position for the tax year to date.

The cash basis is "received in the quarter" for rent and "paid in the quarter" for expenses, with no roll-forward. If rent for May is received in July, it falls into Q2 (the July quarter); if a roof repair invoice is dated March but paid in April, the deduction sits in Q1 (the April quarter) of the new tax year.

The reasonable-belief test for allowable expenses

You can deduct an expense before withholding only where you have a reasonable belief that it is deductible against the landlord's UK rental profit. Regulation 8 of SI 1995/2902 sets the test, and in practice you meet it where:

• The expense falls within a standard rental-expense category (repairs and maintenance, agent commission, landlord insurance, ground rent, service charges, accountancy fees specific to the property, gas safety certificates).
• You have an invoice or other contemporaneous evidence in the property file.
• You have not been told (and have no reason to suspect) that the expense is personal or relates to a different property.

You do not have to second-guess the landlord's full self-assessment position. Genuinely ambiguous items (a furnishing replacement that might be capital, a mortgage interest payment under the section 24 regime, capital works to a structural defect) should not be deducted at the withholding stage; the landlord can claim them on the SA return where appropriate. Conservative withholding is the safer call: over-withholding can be reclaimed by the landlord, whereas under-withholding falls on you under regulation 10.

Expenses paid by the landlord direct

Where the landlord pays an expense directly, without it ever passing through you, you do not deduct it. The landlord recovers the deduction through self-assessment against the full UK rental profit, with the withheld tax credited against the total liability. That is the standard pattern for direct-debit ground rent, broker-arranged insurance, or accountancy fees billed to the landlord directly. You record the gross rent only and compute the withholding on that base.

Worked example: Marlow Lets, Q2 2026 NRL2 for one client

Marlow Lets is a UK letting agent managing 24 non-resident landlord properties. One client is Sanjay, a UK national resident in Dubai, with three Manchester rental flats. For Q2 (1 July to 30 September 2026), Marlow Lets receives:

• Rent: £1,250 per month per flat times 3 flats times 3 months = £11,250 gross.
• Agent commission: 10% of gross rent = £1,125 (Marlow's own fee, paid out of the rent collected before remittance).
• Routine repairs: a boiler service at Flat 2 (£180) and a damp survey at Flat 3 (£420).
• Landlord insurance: paid by Sanjay direct (not deductible at agent level).
• Service charge on Flat 1: paid by Sanjay direct (not deductible at agent level).

NRL2 computation for Sanjay for Q2:

• Gross rent received: £11,250.
• Allowable deductions paid in quarter: £1,125 (commission) + £180 (boiler) + £420 (damp survey) = £1,725.
• Net withholdable: £11,250 - £1,725 = £9,525.
• Tax at 20%: £1,905.

Marlow Lets pays £1,905 to HMRC by 30 October 2026 (within 30 days of the quarter-end) and remits the net £7,620 to Sanjay (£11,250 gross minus £1,725 deductions minus £1,905 withheld). The NRL2 also reports the cumulative tax year position (Q1 plus Q2 totals).

If Sanjay later obtains NRL1 approval on, say, 14 November 2026, Marlow Lets stops withholding from 14 November. Q3 (October to December) becomes an apportioned quarter: rent collected up to 14 November is withheld at 20%, and rent collected from 15 November onwards is paid gross. Both segments appear on the Q3 NRL2, with the apportionment spelled out in the return.

The NRL6 annual certificate

By 5 July following the end of the tax year, you must issue an NRL6 certificate to each non-resident landlord you served during the year. The certificate records:

• The landlord's full name and HMRC reference.
• Total gross rent collected in the year.
• Total allowable deductions paid in the year.
• Total net amount.
• Total tax withheld and paid to HMRC.
• Your identifying details so the landlord can cross-reference.

The landlord uses the NRL6 to claim credit for the withheld tax against the full UK income tax liability on their self-assessment return. That credit is essential: without an NRL6 the landlord cannot reconcile their non-resident self-assessment filing. Issue it late and you attract a separate penalty from the quarterly return failures, and, more practically, a wave of client complaints, because the landlord cannot complete their SA return on time without it.

Apportionment when NRL1 approval arrives mid-quarter

You need the exact date you received HMRC's NRL1 approval letter, not the date HMRC issued it and not the date the landlord forwarded a copy. The operative date is your receipt. From that date onward you pay rent gross without withholding, and rent collected before it in the same quarter is withheld at the standard rate.

The moment the approval letter arrives at the agency, log the date in the property file, switch the rent payment instruction in your property-management system, brief the accounts team, and prepare a covering note for the next NRL2 setting out the apportionment. Keep withholding after the approval date and you over-withhold; the landlord then has to reclaim the excess through their SA return, which delays their cash flow and creates friction with you.

Where the approval letter never reaches you (a common failure point: the landlord receives it and forgets to forward it), you keep withholding. The landlord's recourse is to send you a copy, because the operational duty turns on your receipt, not on HMRC's issue.

The tenant-as-duty-holder scenario

Where no agent is appointed and the rent paid exceeds £100 per week, the duty falls on the tenant. The mechanic is the same as the agent's, scaled to a single landlord. If that tenant is you, the steps below are yours.

Catherine rents a Birmingham flat at £1,500 per month direct from her landlord, who lives in Hong Kong. No agent is involved. Her rent (equivalent to £346 per week) exceeds the £100 threshold, so she is the NRL duty-holder. She registers with the NRL Centre, files an NRL2 each quarter showing £4,500 of gross rent received (the rent the landlord receives from her, with no "deductions" because she has no expenses to deduct), pays £900 (20% of £4,500) to HMRC each quarter, and issues the landlord an NRL6 at year-end showing the £3,600 of tax withheld for the year.

This is rare for managed lettings but common for direct corporate lets and for tenants of small-portfolio landlords who emigrate without engaging an agent. The tenant's main exposure is personal liability for unwithheld tax if they keep paying gross after the landlord becomes non-resident.

Regulation 10: personal liability of the agent

Regulation 10 of SI 1995/2902 is the central exposure of the agent role, and it is the one to take seriously. Where tax should have been withheld but was not, HMRC may assess you personally for the unwithheld amount. Your corporate structure does not shield the responsible individual: in a sole-trader agency, you are liable. In a limited company agency, the company is liable, but HMRC's discovery and recovery framework can reach directors where the company has insufficient assets and there is evidence of culpable conduct.

Three scenarios where regulation 10 bites:

You did not know the landlord became non-resident. The landlord emigrates without telling you, you keep paying gross, and HMRC later issues an assessment for the back-tax. Your defence is that you had no reasonable means of knowing, which in practice depends on whether the management agreement obliged the landlord to notify a change of residence. Without that clause, the discovery-and-mitigation conversation with HMRC is genuinely difficult.

You computed deductions too aggressively. You deducted expenses that did not meet the reasonable-belief test (personal expenses, capital items, expenses for a different property), and the under-withheld portion is recovered from you. Your records, the contemporaneous reasonable-belief notes, and a consistent categorisation discipline all reduce the exposure.

You failed to register. Take on a non-resident landlord, never register, and you operate outside the scheme and never file an NRL2. When HMRC discovers it, the full historic under-withholding, for as long as you were outside the scheme, is yours. No time limit applies for unprompted discovery, so HMRC can reach back further than the standard 4 or 6 year SA discovery windows.

The mitigation is the same in each case: register early, document the reasonable-belief basis for every deduction, get NRL1 letters in writing the moment they arrive, and engage with HMRC promptly if an exposure emerges. Your professional indemnity policy may or may not cover regulatory liabilities of this kind, so check it.

Record-keeping

Six years from the end of the tax year is the standard retention period for NRL agent records, extending where you are aware of an open enquiry. For each landlord, keep:

• Gross rent received: date, amount, source bank account.
• Allowable expenses paid: invoice references, supplier details, paid date, the reasonable-belief categorisation note.
• NRL2 filings: each quarter's return as filed plus the payment confirmation.
• NRL6 copies issued to each landlord with date issued.
• Correspondence with HMRC's NRL Centre.
• Copy of any NRL1 approval letter for each landlord, with the date you received it.

Your records should be reproducible from the standard property-management system without manual reconstruction. An HMRC enquiry typically asks for a sample quarter's NRL2 with full underlying support, and if you cannot produce it within 30 days under regulation 8's reasonable-belief framework you are in a weaker position from the start.

How the agent's quarterly machinery connects to the landlord's annual return

The landlord files a UK self-assessment return reporting full UK rental income for the year, and the NRL6 you issue provides the credit for tax withheld at source. Their SA computation runs: gross rental profit, less allowable expenses (including any you did not deduct at source because of the reasonable-belief test or because the landlord paid direct), less personal allowance (if entitled under section 56 ITA 2007), at the appropriate tax rate (20% to 45% depending on total UK-taxable income). The withheld tax in the NRL6 is credited against the final liability, any excess is repaid, and any shortfall is paid with the SA return.

Your accuracy at the withholding stage is what decides your risk. Under-withholding produces an HMRC enquiry against you under regulation 10; over-withholding produces a refund claim by the landlord that delays their cash flow but does not penalise you. So if you have to err, err slightly high. The reasonable-belief framework gives you room to make sensible judgments, but the shape of the liability rules rewards the conservative line.

For client conversations, it helps to know the full landlord pathway in the NRL scheme guide for landlords and the gross-payment route in the NRL1 approval guide.
