Autumn Budget 2026: How Contractors Should Prepare

HM Treasury confirmed on 31 July 2026 that Chancellor John Healey will deliver his first Budget — and the government's next fiscal statement — on Wednesday 28 October 2026. For contractors and SME builders who've had three years of mid-year tax surprises, that's a firm date to plan around before the next set of rule changes lands. Here's what's already locked in, what's being speculated on, and what's actually worth doing before Budget Day rather than after it.

What's already confirmed, Budget or no Budget

Three changes are already in law regardless of what happens on 28 October, so they're not 'predictions' — they're planning inputs. Making Tax Digital for Income Tax drops its qualifying-income threshold to £30,000 from 6 April 2027, assessed against your 2025-26 Self Assessment return — meaning more sole traders and contractors will be pulled into quarterly digital filing than currently expect it. The Personal Allowance stays frozen at £12,570 and the basic rate limit at £37,700 through to April 2031. And from April 2029, salary sacrifice pension contributions above £2,000 a year lose their National Insurance exemption — relevant if you run a limited company and pay yourself partly through pension contributions.

What the speculation is circling

Every Autumn Budget since 2022 has produced speculation about the self-employed and small-business tax base, and this one is no different — accountancy firms are flagging possible movement on National Insurance for the self-employed, dividend tax rates, and further tightening of allowances. None of it is confirmed, and we're not going to pretend otherwise or offer tax advice based on rumour. What we'd say instead: this is the moment to make sure your bookkeeping is current, not the moment to restructure your business around a guess. A contractor who walks into 28 October with clean, up-to-date records can react fast to whatever's actually announced. One who's three months behind on invoicing can't, whatever the Budget says.

Why this matters more if you're newly self-employed

If you've gone self-employed or set up a limited company in the last 12 months, this will be your first Autumn Budget as a business owner rather than an employee, and the volume of commentary can be overwhelming. The practical advice doesn't change much: keep receipts and invoices current through cloud accounting software now rather than scrambling in January, know your rough turnover for the year to date, and don't make big financial decisions off the back of a headline before the actual policy document is published on gov.uk that afternoon.

“Every Budget cycle, the contractors who do best aren't the ones who guessed right. They're the ones whose books were already in order when the detail landed.”
