What is changing
Budget 2026 announces a two-percentage-point increase in the income-tax rates applying to property income and savings income from April 2027. Employment income, pension income and dividend income are not affected by this particular measure. The Budget’s rates material explains that property rates will be separated from the main income-tax rates from the 2027–28 tax year.
For a UK taxpayer, this means that the tax calculation for a rental property or bank interest may no longer be assessed using the same rate framework as salary income. The exact application will depend on the legislation, the taxpayer’s marginal position and the interaction with allowances and reliefs.
Practical example
Suppose an individual receives salary, rental profit and bank interest. The salary remains subject to the ordinary income-tax structure. Rental profit and savings income will instead be considered under the new property and savings-rate framework. A taxpayer who is close to a band threshold should model whether additional rental profit or interest will push income into a higher rate.
The result is particularly important where a taxpayer has:
- Several personally owned rental properties;
- Large cash deposits or taxable investment income;
- Mortgage interest restrictions that already affect the rental calculation;
- Income split between spouses or civil partners; or
- A property business whose profits fluctuate from year to year.
Planning actions
- Forecast 2026–27 and 2027–28 separately. Do not rely on the previous year’s tax estimate.
- Reconcile gross property income and allowable expenses. Keep invoices, finance records and letting statements together.
- Review ownership. Transfers between spouses, civil partners or companies can have tax, stamp-duty and capital-gains consequences, so obtain professional advice before acting.
- Check payment-on-account exposure. A higher liability may increase payments due through Self Assessment.
- Use available allowances carefully. ISAs and pension contributions may reduce exposure, but contribution limits and access rules must be checked.
What taxpayers should not assume
The announcement does not mean every source of income will rise by two percentage points. The published material distinguishes property and savings income from employment, pension and dividend income. It also does not by itself change the legal treatment of expenses, mortgage finance costs or the residence position of a landlord.
Bottom line
Landlords and savers should treat April 2027 as a planning date, not a distant administrative issue. Build a source-by-source income forecast, preserve evidence for deductions and obtain advice before changing ownership or incorporation arrangements. The official Budget documents identify the policy direction, while final legislation and detailed HMRC guidance should be checked before filing returns affected by the new rates.
