What Changed in 2026/27 for UK Contractors

The headline: dividend tax up 2pp

The single biggest change in the Autumn 2025 Budget for UK contractors is a 2 percentage point increase in dividend tax rates. The new 2026/27 rates are:

• Basic rate dividend: 8.75% → 10.75%
• Higher rate dividend: 33.75% → 35.75%
• Additional rate dividend: 39.35% (unchanged)

The £500 dividend allowance is unchanged. The first £500 of dividends is still taxed at 0%, though it uses up basic rate band space.

This change only affects outside IR35 contractors, because dividends are how outside IR35 income flows. Inside IR35 contractors pay PAYE, which wasn't changed in this budget.

What it means for your take-home

At a £500/day outside IR35 contract over 220 working days, the dividend tax rise costs you about £1,500 per year in take-home compared to 2025/26.

Here's the comparison at typical day rates:

Day rate	Outside net 2025/26	Outside net 2026/27	YoY change
£400/day	~£60,800	£59,543	−£1,257
£500/day	~£71,413	£69,932	−£1,481
£750/day	~£91,800	£90,163	−£1,637
£1,000/day	~£116,200	£114,681	−£1,519

The YoY drop is relatively stable in absolute terms (£1,200–£1,700 across the rate range) because the 2pp increase compounds with the dividend volume rather than scaling with revenue.

The inside vs outside gap narrowed

Because dividend tax only affects outside IR35 contractors, and inside IR35 contractors pay PAYE that wasn't changed, the gap between inside and outside take-home shrunk in 2026/27.

In 2025/26 at £500/day, the gap between matched-rate inside and outside was roughly £5,800. In 2026/27 it's about £4,300. The historical "20–25% uplift required to match outside" rule of thumb is no longer accurate at most day rates.

At £500/day in 2026/27, the matching inside rate is about £545/day — a 9% uplift, not 20%. Above £700/day the uplift required drops to single digits.

What didn't change but is still painful

Several material costs from previous years carry over unchanged into 2026/27:

• Employer NI rate: 15% (raised from 13.8% in April 2025)
• Employer NI secondary threshold: £5,000 (lowered from £9,100 in April 2025)
• Apprenticeship Levy: 0.5% (unchanged)
• Personal allowance: £12,570 (frozen)
• Basic rate threshold: £50,270 (frozen)
• Additional rate threshold: £125,140 (frozen)
• Employee NI: 8% / 2% (unchanged from April 2024 cut)

The frozen thresholds are particularly impactful because of fiscal drag — as contractor day rates rise with inflation, more contractors get pushed into higher tax bands. The personal allowance and basic rate threshold are now frozen until April 2031 per HMRC's published plans.

Student loan thresholds nudged up

If you have a student loan, the repayment thresholds increased modestly for 2026/27:

• Plan 1: £26,065 → £26,900
• Plan 2: £28,470 → £29,385 (then frozen until 2030)
• Plan 4: £32,745 → £33,795
• Postgraduate Loan: £21,000 (unchanged)

Repayment rates are unchanged: 9% for Plans 1/2/4, 6% for PG.

What this means in practice

For an outside IR35 contractor in 2026/27:

• You take home roughly £1,200–£1,700 less per year than you did at the same day rate last year.
• The gap between you and an inside IR35 contractor on the same headline rate is smaller than it used to be.
• If you're being asked to switch from outside to inside, the uplift you need to demand is probably less than the "20%" you'd have asked for last year — but you still need a real number based on your circumstances, not a rule of thumb.

For an inside IR35 contractor in 2026/27:

• Your take-home is unchanged from 2025/26 at the same contract rate.
• Relatively speaking, you're in a slightly better position vs your outside IR35 peers than you were a year ago.
• The case for negotiating an "outside" status is materially weaker than it used to be — the prize for getting out has shrunk.

Forward look: frozen until April 2031

The personal allowance, basic rate threshold, and most NI thresholds are now confirmed frozen until April 2031. That means fiscal drag continues for the next five years — anyone whose contract rate rises with inflation pays a higher effective tax rate each year, even if headline rates don't move.

For contractors planning multi-year, this matters more than the dividend tax change. The compounding effect of fiscal drag on a contractor whose rate moves from £600 to £750/day over five years is materially larger than a one-off 2pp dividend tax rise.

Tax thresholds aren't the only thing worth tracking. IR35 case law and HMRC determination practice keeps moving — for ongoing updates on UK IR35 reform, tribunal rulings, and status-determination guidance, ir35update.co.uk is a useful resource to keep an eye on.

What to do about it

• Maximise pension contributions. Both outside (via employer contribution) and inside (via salary sacrifice) pension routes are highly tax-efficient. The 2pp dividend tax rise makes outside-IR35 pension contributions slightly more attractive on the margin.
• Negotiate inside rates based on real figures, not 20% rule of thumb. Use a calculator that uses 2026/27 figures specifically.
• Don't let stale advice from 2024 or earlier shape your decisions. The numbers have moved.
