Moving to Australia doesn’t mean selling your UK property. But it does mean understanding the tax implications – because HMRC still taxes UK property income, and ATO wants to know about it too.
This guide covers what Australia residents need to know about UK property taxation.
Quick Summary
Key points:
- ⚠️ UK rental income ALWAYS taxed in UK
- ⚠️ Must also declare in Australian tax return (claim foreign tax credit)

The Basics
Does Australia Residency Change UK Property Tax?
No – UK property income is still taxed in UK.
However: As Australian tax resident, you must ALSO declare UK rental income in Australian return.
UK-Australia tax treaty prevents double taxation:
- Pay UK tax on rental
- Declare in Australian return
- Claim foreign tax credit for UK tax paid
- Net effect: Usually pay UK tax only (UK rate often higher)
Rental Income: UK Side
Non-Resident Landlord Scheme
Register with HMRC to receive rent gross (without 20% withholding).
How:
- Complete form NRL1
- Submit to HMRC: bst.nrl@hmrc.gov.uk
- Approval: 4-6 weeks
- Notify agent (stop withholding)
Timeline: Register BEFORE leaving UK or immediately upon moving.
UK Tax on Rental Income
Taxed at marginal rates (20-45%) after allowable expenses.
Deductible:
- Letting agent fees
- Maintenance and repairs
- Insurance
- Ground rent
NOT deductible:
- Mortgage capital
- Improvements
- Your time
Mortgage interest: 20% tax credit (not full deduction).
Rental Income: Australian Side
Must declare UK rental income in Australian tax return.
How it works:
- Include UK rental income (in AUD)
- Include allowable expenses
- Calculate net UK rental profit
- Add to Australian taxable income
- Claim foreign income tax offset (FITO) for UK tax paid
Net result: Usually no additional Australian tax (UK tax rate typically higher than Australian).
But if UK tax < Australian tax: You pay difference to ATO.

Capital Gains Tax: UK Side
Selling UK property triggers UK CGT.
Rates:
- Basic rate: 18%
- Higher/additional rate: 28%
Calculation:
Gain = Sale price – Purchase price – Allowable costs
Annual allowance: £3,000 (2026/27)
Main Residence Relief – GONE for Non-Residents
Critical change (2017): Non-residents lost main residence CGT exemption.
Before 2017: Could claim relief for years as main residence
From 2017: No relief for non-residents, even for pre-2017 ownership
Exception: Property was main residence AND sold within prescribed timeframe after moving (complex rules).
60-Day Reporting
Non-residents must report and pay UK CGT within 60 days of completion.
Miss deadline: 5% penalty + interest.
Capital Gains Tax: Australian Side
Australia taxes worldwide capital gains for residents.
Foreign Property CGT
When you sell UK property:
- UK CGT paid first (18-28%)
- Declare in Australian return
- Calculate Australian CGT:
- 50% discount if owned 12+ months (doesn’t apply to foreign property acquired while non-resident)
- Marginal tax rate applies
- Claim foreign tax credit for UK CGT paid
Net effect: Usually pay UK tax only (but must file in both countries).
CGT Calculation Differences
UK calculates gain in GBP
Australia calculates in AUD
Currency fluctuations can create gains or losses purely from exchange rate changes. The interaction between UK and Australian CGT calculations, currency conversion, and foreign tax credit claims is complex.
Should You Sell or Keep?
Reasons to Keep
Financial:
- Rental yield covers costs
- Long-term appreciation
- UK property exposure
- GBP diversification
Personal:
- Plan to return to UK
- Family use
- Sentimental value
Reasons to Sell
Financial:
- Rental doesn’t cover mortgage + tax
- UK market concerns
- Want capital for Australian property
Practical:
- Management hassle (16-hour time difference)
- Currency complications
- Double tax filing
Tax:
- No main residence relief anyway (lost in 2017)
- CGT won’t get better with time
- Simplifies tax position
The break-even analysis depends on rental yield, appreciation expectations, Australian property market, and multiple other factors.
