Non-UK resident landlords with UK rental income are within UK income tax (or corporation tax for non-resident companies) and must file annual Self Assessment returns to report the income, claim allowable expenses, and settle any tax liability. The mechanics overlap substantially with UK-resident landlord filing but with three distinct additions: the Non-Resident Landlord (NRL) scheme governing whether rent is received gross or net, the SA109 residence supplement, and the broader 60-day CGT on UK property regime that applies to all UK land disposals by non-residents.

This page sets out the SA filing requirements specifically. For NRL withholding mechanics see our companion page on NRL withholding tax.

Who counts as a non-resident landlord

The NRL scheme test (for withholding) is different from the Statutory Residence Test (for general income tax residence). For NRL purposes, a person is a non-resident landlord if their usual place of abode is outside the UK. In practice this means being physically absent from the UK for more than six months in the tax year, with the property still in the UK. For Self Assessment more broadly, residence is determined under the Statutory Residence Test (Schedule 45 to Finance Act 2013), which is a more nuanced multi-factor test.

The two can diverge. An individual who fails the SRT residence test in a borderline year but is physically present in the UK for most of the year may still be a non-resident for SRT purposes while not being a non-resident landlord under the NRL scheme. The reverse is also possible. The mechanics are checked separately for each test.

For most clearly non-resident landlords (full-time overseas residents, expats settled abroad, foreign-domiciled investors), both tests point the same way and the practical position is straightforward.

The two systems: NRL scheme and Self Assessment

Two distinct systems govern non-resident landlord taxation:

SystemWhat it doesForms involved
NRL schemeControls whether rent is paid gross or net of basic-rate (20%) withholding taxNRL1 (individual), NRL2 (company), NRL3 (trust)
Self AssessmentAnnual computation of actual UK income tax liability, with credit for any tax withheldSA100, SA105, SA109, plus other supplementary pages as relevant

Almost every non-resident landlord is within both: NRL scheme registration to receive rent gross, then SA filing to compute the actual liability. Without NRL scheme approval, the lettings agent (or tenant where rent exceeds £100 per week with no agent) must withhold 20% and remit to HMRC quarterly; the landlord then claims credit on the SA return. The two mechanics produce the same final outcome but the cashflow timing is materially better with NRL scheme approval.

The SA filing pack for non-resident landlords

The minimum filing pack for a non-resident individual landlord with UK rental income:

  • SA100 – the main Self Assessment return covering personal details, all sources of UK income, and the tax calculation summary.
  • SA105 – the UK Property supplement, showing rental income, allowable expenses (with the Section 24 mortgage interest restriction applied), and the property business profit or loss.
  • SA109 – the Residence, Remittance basis supplement, declaring non-resident status and giving the basis on which the landlord is non-resident.

Additional pages where relevant:

  • SA106 – Foreign income. Where the landlord has other UK-source income subject to limited tax (interest, dividends), or where home-country income needs to interact with the UK calculation.
  • SA108 – Capital gains. Required for property disposals (which are also separately reported through the 60-day CGT on UK property service).
  • SA101 – Additional information. Used for non-standard items.

Non-residents cannot use HMRC's free online filing service: the residence supplement (SA109) is not supported on the HMRC service. Filing options are either paper (deadline 31 October) or commercial filing software (deadline 31 January). This is the most common practical barrier non-resident landlords hit when trying to file themselves; many move to a UK accountant once they realise the free HMRC route is closed to them.

How the SA calculation works

Mechanically similar to a UK resident SA:

  1. Total rental income for the tax year, including from all UK properties
  2. Less allowable expenses (letting agent fees, repairs, insurance, professional fees, ground rent, replacement of domestic items relief)
  3. Mortgage interest and other finance costs are added back (Section 24); the 20% basic-rate credit is applied later in the calculation
  4. Personal allowance applied (£12,570 for 2026/27, with the £100,000 taper; some non-residents lose the personal allowance entirely depending on their country of residence and any applicable treaty)
  5. Tax computed at general income tax rates (20/40/45% in 2026/27, moving to 22/42/47% on property income from April 2027)
  6. Section 24 basic-rate credit deducted
  7. Tax already withheld through the NRL scheme (where applicable) deducted as a credit against the final liability
  8. Balancing payment due by 31 January following the tax year end

The personal allowance availability for non-residents is one of the most common areas of confusion. UK and EEA citizens generally retain the personal allowance regardless of residence. Citizens of other countries depend on the specific double taxation treaty: some treaties preserve the allowance, others remove it. Where the personal allowance is lost, the entire taxable income is at the marginal rate.

Worked example: non-resident landlord with two UK properties

Maria is a Spanish resident with two UK rental properties, both with mortgages. For 2026/27:

  • Property A gross rent: £14,400
  • Property A allowable expenses (non-finance): £2,800
  • Property A mortgage interest: £4,500
  • Property B gross rent: £11,000
  • Property B allowable expenses (non-finance): £1,900
  • Property B mortgage interest: £3,200
  • Maria is registered under the NRL scheme and receives rent gross
  • UK personal allowance preserved by UK-Spain treaty

Calculation:

  • Total rental income: £25,400
  • Total non-finance expenses: £4,700
  • Property profit before finance cost restriction: £20,700
  • Personal allowance applied: £12,570
  • Taxable income: £8,130
  • Income tax at 20% basic rate: £1,626
  • Section 24 basic-rate credit on mortgage interest: (£4,500 + £3,200) × 20% = £1,540
  • Net UK income tax: £1,626 − £1,540 = £86

The £86 final liability is small because Maria's property profit is modest and within the basic-rate band. Spain will tax the same rental income under Spanish rules; the UK-Spain treaty provides credit for UK tax paid, so Maria's combined UK-plus-Spain liability typically lands at the higher of the two countries' tax positions.

Capital gains on UK property: the 60-day return

The 60-day CGT on UK property regime applies more broadly to non-residents than to UK residents. Non-residents must file a 60-day return for every disposal of UK land, regardless of whether tax is due, since:

  • April 2015: residential property disposals brought within UK CGT for non-residents
  • April 2019: extended to all UK land (commercial and residential) plus indirect interests in UK property-rich entities

Mechanics for non-resident disposals:

  • 60-day return through HMRC's CGT on UK property service for every disposal
  • Rebasing applied at 5 April 2015 (residential) or 5 April 2019 (non-residential); older base costs do not flow through unchanged
  • UK rates (18% / 24% on residential property, same on commercial post-30 October 2024)
  • £3,000 AEA available where the individual is otherwise in scope
  • Treaty relief may apply where the same disposal is taxed in the home country

The disposal is also reported on the SA108 capital gains pages of the annual SA return, with the 60-day tax credited against the final SA liability. Full mechanics in our 60-day CGT deadlines guide.

Double taxation treaty interaction

Where the landlord is tax-resident in a country with which the UK has a double taxation treaty, the treaty governs how the same property income is taxed in both jurisdictions. The general pattern:

  • The UK taxes the property income under domestic rules (UK has the primary taxing right on UK property income under most treaties)
  • The home country also taxes the same income (residence-based taxation under most treaties)
  • The home country gives relief for UK tax paid, usually by tax credit against the home-country liability on the same income
  • Effective combined rate = the higher of UK or home-country rate, but not the sum

Mechanically, this means:

  • Pay UK tax under SA, on the timetable described above
  • Obtain a UK tax certificate (typically through the SA return process or by direct request to HMRC) confirming UK tax paid
  • Claim treaty credit in the home country tax return

The specific treaty mechanics vary. Some treaties have unusual carve-outs for property income; some apply withholding tax mechanisms; some require advance ruling for material relief claims. Specialist advice in both jurisdictions is usually warranted for non-resident landlords with material UK portfolios.

MTD for Income Tax: applies to non-resident sole-trader landlords too

MTD for Income Tax applies to sole-trader landlords above the prevailing income threshold regardless of UK residence. From 6 April 2026, sole-trader landlords (including non-residents) with gross UK rental income above £50,000 are in scope, dropping to £30,000 from April 2027 and £20,000 from April 2028.

Practical implications for non-resident landlords in scope:

  • MTD-compatible software, capable of submitting to HMRC's MTD API
  • Quarterly updates by the 7th of the second month after each quarter end
  • Annual final declaration by 31 January following the tax year
  • Points-based late submission penalty regime (4 points triggers a £200 financial penalty)

The software market is mature for UK-resident landlords; for non-resident landlords, the choice is narrower because not all MTD products are well-suited to non-resident filing patterns. Sense-checking software choice with a UK property accountant before committing is sensible.

Non-resident corporate landlords

Since 6 April 2020, non-resident companies' UK property income has been within UK corporation tax rather than income tax. This means:

  • Corporation tax return (CT600) rather than the individual SA return
  • Corporation tax rates (19% / 25%, with marginal relief between £50,000 and £250,000) regardless of residence
  • Section 24 does not apply (mortgage interest is fully deductible against trading profit inside a company)
  • Different accounting period from the tax year, set by the company's articles
  • ATED returns may apply where any property exceeds £500,000 in value

Withholding tax via the NRL scheme applies in the same way to non-resident companies as to individuals: NRL2 registration allows rent to be paid gross. The April 2027 income tax change does not affect non-resident companies, because they are within corporation tax (which is unaffected by the change).

Penalties for non-compliance

Penalty regimes for non-resident landlords run on three separate clocks:

  • NRL scheme penalties. Failure by an agent to withhold and account where required can produce a determination on the agent. Failure by a landlord to register or to comply with NRL scheme conditions is a less common penalty but can apply.
  • Self Assessment penalties. Standard SA regime: £100 fixed penalty after the filing deadline, daily £10 penalties after 3 months (up to £900), 5% of tax (minimum £300) at 6 and 12 months, plus tax-geared penalties for deliberate or concealed default.
  • 60-day CGT penalties. Late filing of the 60-day return is £100 from day 61, daily £10 penalties after 3 months (up to £900), 5% surcharge at 6 months, and tax-geared penalties for deliberate default.

The penalty regimes apply independently, so a missed 60-day return plus a missed SA filing can produce a stack of penalties exceeding the underlying tax due.

Where this fits in the wider tax picture

Non-resident landlord SA filing is one of several touch points. The broader compliance picture includes:

  • NRL scheme registration and ongoing notification (separate from SA)
  • 60-day CGT on UK property for every disposal
  • SDLT on acquisition (with the 2% non-resident surcharge on top of the 5% additional dwellings surcharge)
  • ATED for company-held property over £500,000
  • Double taxation treaty management in the home country
  • Eventual IHT exposure for foreign-domiciled individuals (UK property is always within UK IHT, regardless of domicile)

For most non-resident landlords, the cost of professional UK property tax support is small relative to the value of getting the filing position right across all of these. Mistakes compound through penalties, interest and lost treaty relief opportunities.
