Autumn Budget 2025: Rachel Reeves confirmed that new ‘National’ investment income tax rates were being introduced and would all increase by 2% over income tax rates.
Finance costs credit: Mortgage and loan interest payments can no longer be fully offset against you income liability but a tax credit is offered at 20% of the finance interest costs only. This has been confirmed that it will increase to 22%, meaning that property income tax basic rate tax payers (22%) in England, Wales and Northern Irland will not face any issues as they then get a 22% credit with higher rate and additional rate property tax payers still only facing a restriction on 20% (42% property tax less 22% credit) and 25% (47% property tax less 22% credit) of finance interest costs.
The problem being that investment income taxes are set at a National Level but normal income tax rates for earnings and pensions are set at a devolved government level i.e., Scotland sets it own rates of income tax.
The Scottish Budget 2026/27 was published on 13 January 2026, and we uploaded our own video/article summary yesterday:
Scotland’s Property Tax Problem
Property Income Tax is a brand-new tax, given it is currently taxed at our normal rates of income taxes. The problems is that devolved government legislation means can set their own rates of income tax (legislation does not account for the new Property Income Tax).
Scotland (already sets its own income tax rates) and Wales (has yet to set own its own income tax rates) but they both currently have no power to set new property income tax rates or property tax reducer credits. Without action:
A Basic Rate Taxpayer in England (20%), will be liable to 22% Property Income Tax but with a 22% tax reducer for finance interest costs meaning the taxpayer is net neutral.
A Higher Rate Taxpayer in England (40%), will be liable to 42% Property Income Tax but with a 22% tax reducer for finance interest costs meaning property tax revenue remains the same.
Comment
Clearly, the UK government will need to take some action to expand the powers of devolved governments before April 2027, to ensure Scotland (and Wales if the do set their own rates), have powers to collect property income taxes and offer tax reducer credits at the levels that they wish to.
