Individuals in the United Kingdom are entitled to a tax-free Personal Allowance, which determines the amount of income they can earn before tax is due. Despite remaining unchanged in recent years, opportunities exist for married couples and those in civil partnerships to increase their tax-free earnings.
By claiming the Marriage Allowance and making use of “backdating” provisions, eligible households may receive a significant rebate. This article explores the current position on Personal Allowance, the effects of fiscal policy, and the practical steps for couples to enhance their tax-free income.
Current Status of the UK Personal Allowance
The Personal Allowance is the threshold of income that a person can receive each year without paying income tax. For the 2024-25 tax year, it remains set at £12,570 and has been frozen at this level since 2021.
According to official Treasury statements, this freeze is expected to be maintained until at least 2031, as part of wider fiscal policy.
The freeze means that, while people's earnings may rise with inflation, the threshold at which tax becomes payable is not due to rise, affecting a growing number of taxpayers.
Fiscal Drag and Its Financial Impact
The continued freeze of the Personal Allowance contributes to “fiscal drag.” As wages increase, more individuals’ earnings surpass the static threshold, resulting in more income being subject to tax.
This policy is projected to increase tax bills for many households, especially as inflation drives up pay. Fiscal analysts warn that such measures indirectly raise overall tax revenue without changing headline rates, impacting both new and existing taxpayers.
Understanding the Income Tax Bands
Income tax in the UK is structured across several bands. Any earnings above the Personal Allowance are taxed at the basic rate of 20%. Higher rate taxpayers face a 40% charge on income exceeding £50,270, while those with income above £125,140 are subject to a 45% additional rate.
The static nature of these thresholds, in conjunction with the fixed Personal Allowance, further contributes to increased overall tax liabilities for individuals as their earnings grow.
Options for Increasing Tax-Free Allowance
The government provides limited ways for taxpayers to increase their tax-free income. One notable option targets those who are married or in a civil partnership.
Through the Marriage Allowance, eligible couples can transfer a portion of their unused Personal Allowance from one partner to another, meaning the receiving partner can reduce their tax bill and increase their effective tax-free income.
Marriage Allowance: Eligibility and Application
Marriage Allowance allows an individual who earns less than the Personal Allowance to transfer up to £1,260 of that unused allowance to their partner. To qualify, one partner's income must be below £12,570, and the other partner’s must be within the basic rate band (£12,570 to £50,270 after pension contributions).
This transfer results in a reduction in the recipient’s annual tax bill by up to £252, representing 20% of £1,260. Furthermore, claims for Marriage Allowance can be backdated for up to four previous tax years, provided eligibility was met in each year.
This allows couples to receive a rebate of up to £1,260 for a five-year period. The funds are provided as a tax code adjustment or, in some cases, a lump sum payment from HM Revenue & Customs.
Final Summary
While the Personal Allowance remains frozen at £12,570 through the end of the decade, strategies exist to optimise household tax efficiency. Marriage Allowance presents a practical option for eligible couples to increase their combined tax-free income.
By backdating claims, households may recoup up to £1,260 in overpaid tax, offering meaningful financial support amid fiscal drag.
