Autumn Budget 2026: landlord and overseas-owner research report
Prepared by SJW UK Properties Research Team. Budget delivered: 28 October 2026. Information checked to: 5 November 2026.
This report develops SJW’s landlord briefing using subsequent Treasury and HMRC publications. It focuses on personally owned UK rental housing and the practical questions facing overseas landlords. Announced measures with a future start date should be distinguished from rules already in force.
Executive assessment
The immediate planning issue is the proposed increase in personal property income tax from April 2027, alongside a new cost for high-value homes from 2028. Our assessment is that landlords should compare after-tax cash flow, borrowing and compliance costs property by property. A headline rent or a single tax rate cannot establish whether an investment remains suitable.
1. Property income tax: the April 2027 position
The Treasury sets out proposed property income rates of 24%, 44% and 49% for 2027/28 in England, Wales and Northern Ireland. The measures are to be legislated for in Finance Bill 2026–27, taking effect on 6 April 2027. Scottish arrangements require a separate check.
The further two-percentage-point rise is measured against the previously planned 22%, 42% and 47% rates. Compared with 2026/27 rates of 20%, 40% and 45%, the cumulative difference is four points. For illustration, £20,000 of taxable rental profit wholly within the higher-rate band gives an £800 difference between 40% and 44%, before allowances, finance-cost relief or other adjustments. This is arithmetic, not a personal tax forecast.
Residential finance-cost relief for individual landlords must be calculated using the applicable property basic rate and statutory restrictions. Mortgage interest should not simply be treated as an ordinary deduction from rental profit. An accountant should check the calculation against the landlord’s wider income.
2. Overseas individuals and companies need different assessments
Living overseas does not remove UK rental-income obligations. Collection arrangements under the Non-resident Landlord Scheme and the final annual tax calculation are distinct. The personal property-income rate rise does not directly apply to company profits, but incorporation is not an automatic saving: Corporation Tax, extracting funds, borrowing terms and the costs of transferring an existing property all need consideration.
There are around five months from this report’s assessment date to April 2027, rather than more than a year. Start gathering records now. Obtain individual tax and legal advice before changing ownership in response to a headline rate.
3. Buying and selling: assess the transaction, not a blanket headline
For residential transactions subject to SDLT, the two-percentage-point non-resident surcharge and the five-point additional-dwelling uplift remain subject to their respective conditions. They can apply together; neither is a flat rate for the entire purchase. SDLT applies in England and Northern Ireland, with separate systems in Scotland and Wales.
The 18% and 24% residential Capital Gains Tax bands provide general context; the actual liability depends on income, costs, reliefs and the disposal. Non-resident individuals generally need to report UK property disposals within 60 days of completion and pay tax due. Reporting can still be required where there is no tax or a loss. Companies follow Corporation Tax rules instead.
4. High-value homes: value and occupation matter
The High Value Council Tax Surcharge is planned from April 2028 for residential property in England valued at £2 million or more on the 2026 basis. Owners are liable. Published annual charging bands are £2,500, £3,500, £5,000 and £7,500, subject to valuation and applicable reliefs. An asking price alone does not determine the band.
The updated Treasury guidance confirms a 100% premium for properties left substantially unfurnished and unoccupied for at least 12 months. This concerns occupation and use; it is not a blanket doubling for overseas owners. Owners should check their position against the published details and subsequent updates.
5. Making Tax Digital: the threshold is not net profit
The first MTD for Income Tax phase began on 6 April 2026 for qualifying individuals with combined self-employment and property income above £50,000 in 2024/25. The next phase starts on 6 April 2027 for those above £30,000 in 2025/26. Relevant gross income before expenses, rather than net rental profit, is used, with exemptions and individual circumstances to check.
Preparation includes digital records, compatible software, quarterly updates and the annual return. Overseas landlords should ask their tax agent to confirm their position and agree how the managing agent will supply rent, expense and repair records.
6. Market implications are scenarios, not promises
Higher tax may affect some landlords’ decisions, but supply, tenant demand, property condition and finance interact. We do not infer that all London rents will rise or that company ownership will always outperform personal ownership. Nor can the temporary bank surcharge change be translated directly into a particular mortgage-rate increase.
Your First Home supports eligible first-time buyers purchasing a main-home new build in England; it is not a buy-to-let subsidy. Its effect on tenants becoming buyers remains to be seen. Energy support also depends on eligibility, who pays the bills and consumption: bills-inclusive landlords should not automatically assume a fixed saving.
Actions for landlords
Assemble rent, operating expenses, finance costs, ownership, residence and valuation records. Review cash flow separately for 2026/27, 2027/28 and 2028/29, then ask an accountant to confirm the tax treatment and a solicitor or lender to explain any restructuring conditions and costs.
