The UK’s income tax thresholds have been frozen since April 2021. Under current policy, they stay frozen until April 2031 – a full decade of standstill. No headline rate rises. No new taxes. Just frozen thresholds quietly doing the work.
That’s what is fiscal drag in practice: as wages and profits rise with inflation, more income falls into higher tax bands without any formal rate increase. HMRC collected record tax receipts in 2025/26 – up 9.3% year-on-year – with frozen thresholds identified as a significant driver. For business owners, the impact is layered. And the window to act on it is now.
What Is Fiscal Drag and How Does It Affect UK Businesses?
The fiscal drag meaning is straightforward: when tax thresholds don’t keep pace with inflation or wage growth, a larger share of real income becomes taxable, even when purchasing power hasn’t materially changed.
If the Personal Allowance had risen with inflation since 2021, it would be meaningfully higher than it is today. That gap represents income that’s now taxed at the basic rate that wasn’t before. Multiply that across a workforce and the employer NI implications compound the problem further.
For limited company directors, the issue isn’t just the basic rate band. The higher rate threshold has been frozen since 2021, meaning that as dividends and salary creep upward with business growth, more falls into the 40% band. From April 2026, dividend tax rates also rose across all bands – catching directors at precisely the moment thresholds stood still.
The most punishing stretch is the band where the Personal Allowance is progressively withdrawn, creating an effective marginal rate of around 60%. More business owners are drifting into this band as profits grow, often without realising it until the tax bill arrives.
How Can Fiscal Drag Affect Business Owners' Income and Dividends?
To define fiscal drag in business terms: it’s the gap between what you’d pay under indexed thresholds and what you’re actually paying under frozen ones – and that gap widens every year.
For a director taking a combination of salary and dividends, the April 2026 dividend tax rate increases have changed the arithmetic meaningfully. A director whose total income was comfortably within the basic rate band two years ago may now be straddling the higher rate threshold.
Income Tax receipts have increased substantially since thresholds were frozen in 2021. That’s not businesses paying more because of rate rises – it’s fiscal drag doing exactly what it’s designed to do.
Which Strategic Tax Planning Measures Can Reduce Fiscal Drag?
The measures that work are the ones that reduce or redirect taxable income before it reaches the problematic thresholds.
Pension contributions. The most straightforward mitigation. Employer pension contributions are deductible for Corporation Tax and don’t attract employer NIC. For directors approaching the personal allowance taper threshold, contributions funded through the company reduce both personal taxable income and the Corporation Tax bill simultaneously. Carry forward of unused Annual Allowances from previous years can make this particularly powerful.
Salary sacrifice arrangements. Electric vehicles under salary sacrifice remain highly tax-efficient – the Benefit in Kind rate is low, reducing gross pay for both Income Tax and NIC purposes. From April 2026, HMRC has tightened salary sacrifice rules for some non-cash benefits, so the specific arrangement matters and is worth reviewing.
Optimising dividend timing and amounts. Where a director’s income is variable, managing the tax year in which dividends are declared can keep income below the higher rate threshold or the personal allowance taper in years where that’s achievable. This requires forward planning, not a retrospective decision.
ISA contributions for investment income. ISAs don’t reduce this year’s Income Tax bill, but they shelter future dividend income and capital gains from the higher rates that now apply. For business owners with retained profits or personal investment portfolios, maximising ISA allowances reduces the long-term fiscal drag exposure.
Spouse or civil partner income planning. Where a business owner’s spouse or civil partner has unused Personal Allowance or basic rate band, structuring dividend payments or profit sharing accordingly – within HMRC’s settlements legislation – reduces the household tax burden without additional complexity.
When Should Businesses Review Their Tax Planning Strategy?
Before the tax year ends, not after it. Most of the measures above need to be made before 5 April, not in January when accounts are being prepared.
The threshold freeze running to 2031 isn’t a temporary problem to wait out. It’s a structural feature of the UK tax landscape for the next five years. Business owners whose tax planning was built around pre-freeze assumptions are almost certainly paying more than they need to and that gap compounds annually.
Befree’s tax outsourcing services support UK accountancy firms and businesses with proactive tax planning – including year-round reviews that address fiscal drag exposure rather than reactive compliance at year-end.
The Thresholds Aren't Moving – But Your Tax Position Can
What is fiscal drag ultimately? It’s the Government collecting more tax without changing the rates. The remedy isn’t waiting for thresholds to unfreeze – it’s structuring income, contributions, and profit extraction in ways that reduce the exposure year on year.
The businesses that come out of the threshold freeze period in the strongest position are the ones that treated tax planning as an ongoing process, not a once-a-year exercise.
