Autumn Budget 2025: what changed for UK contractors

1. Dividend tax up 2pp on basic and higher bands

The single biggest change for Ltd-company contractors. The three dividend rates moved as follows:

For a contractor on £500/day taking the standard £12,570 director salary plus dividends from a Ltd, this works out to about £900–£1,100 of extra dividend tax per year. The exact bite depends on your day rate and how the dividends split across bands; if most of your dividends are in the higher band (typical at £400–£700/day), the +2pp on the higher rate hits the largest portion of your dividend income.

What it means in practice:the Ltd advantage over umbrella narrows. At £500/day the Ltd advantage was about £4,500/year before this change; it's now closer to £3,600/year. Above ~£700/day where the additional band was already wider, the change has less impact (the additional rate didn't move). Run your specifics through the umbrella vs limited calculator.

2. NI threshold freeze extended to April 2031

The income-tax personal allowance (£12,570) and the higher- rate threshold (£50,270) were already frozen until April 2028 under the previous government's policy. The November 2025 statement extended that freeze to April 2031: a further three years of real-terms tax rises through fiscal drag.

For a contractor earning at higher-rate level, the extension means that with even modest income growth over the next few years, an increasing share of their pay sits in the higher band each year. The effect compounds the longer it runs.

The Class 1 NI thresholds and Apprenticeship Levy threshold are also caught in the freeze. The £5,000 employer-NI secondary threshold (which was reduced from £9,100 in 2024/25) stays at £5,000 through 2031 unless future Budgets change it. For umbrella contractors, this means employer NI continues to take a meaningful chunk of the assignment rate.

3. Dividend allowance stayed at £500 (didn't shrink further)

The £500 dividend allowance has been on a downward trajectory since 2017 (£5,000 → £2,000 → £1,000 → £500). The November 2025 statement left it at £500, frozen, not cut further. That's mildly good news.

But the broader story is that the dividend allowance has been politically easy to cut: it affects a relatively narrow band of taxpayers (mostly Ltd-company directors and sizeable individual investors) and doesn't generate the headlines a personal-allowance change would. There's no specific announcement that it's frozen long-term; the next Chancellor could trim again. Plan accordingly.

What didn't change (and why that matters)

• Corporation tax bands and rates stayed the same: 19% small-profits to £50,000, marginal relief to £250,000, 25% main rate above. The 26.5% effective marginal rate inside the relief band continues to be the highest effective marginal CT rate on a UK Ltd.
• Off-payroll working rules (Chapter 10) are unchanged, engager-determines-status for medium/large clients remains the regime. The October 2024 off-set provisions (allowing HMRC to credit already-paid tax against engager liability) were not reversed.
• Small-client exemption thresholds were raised in April 2025 to £15m turnover / £7.5m balance sheet / 50 employees. Already in effect; no Budget change.
• VAT registration threshold stayed at £90,000 (raised from £85,000 in April 2024). No further movement.

Net effect on a typical contractor

For our canonical £500/day Ltd contractor (220 days, £12,570 director salary, no student loans, rUK), the 2026/27 net to pocket is about £69,129 after all changes. The same contractor in 2025/26 with the older dividend rates would have netted about £70,100: so the Autumn Budget 2025 changes cost roughly £970/year at this rate level. Higher day rates take a slightly bigger hit because more dividends sit in the higher band that rose 2pp.

Inside-IR35 umbrella contractors are largely unaffected by the dividend changes (they don't take dividends), but the threshold-freeze extension is a slow-burning real- terms tax rise that catches up over the years.

The single biggest mitigation lever, for both routes — remains pension contributions. Via umbrella, salary- sacrifice into pension captures both employee and employer NI savings (effective 50–60% marginal saving for higher-rate contractors). Via Ltd, employer pension contributions go in pre-CT and bypass dividend tax entirely. At post-Autumn-Budget rates, the case for increased pension contribution is stronger than it was a year ago.
