The most important part of Autumn Budget 2026 for anyone who engages contractors in the UK is what it left out.
Chancellor John Healey's first Budget, delivered on 28 October, announced no further change to IR35 (the off-payroll working rules). It did set out more compliance capacity at HMRC, across the tax system as a whole, along with a set of planned measures and consultations that will play out over the next few years. Here's what changed, what didn't, and what's worth watching into 2027.
No further change to the off-payroll working rules
The Budget announced no further change to IR35, Status Determination Statements (SDS) or fee-payer liability. After months of calls from the contractor sector for an "IR35 reset", the framework that has applied to the private sector since April 2021 continues.
The thresholds that determine whether a non-public-sector client is 'small' for the off-payroll working rules increased from 6 April 2025 to £15 million turnover and a £7.5 million balance-sheet total, while the 50-employee threshold remained unchanged. A company is small if it meets at least two of those three criteria. The practical effect for most businesses with standard accounting periods is likely to arise from 2027/28. Group, parent-company, joint-venture and connected-person rules can affect the assessment, so organisations close to the limits should confirm their position.
For organisations within scope, continuity is useful. If you already assess engagements and issue an SDS where the rules require one, the Budget gives you no new process to build. An SDS on its own isn't a guarantee, though. A determination needs to be made with reasonable care and reflect the working practices of how the work actually happens, not just what the contract says, so it's worth revisiting when an assignment's responsibilities, control or ways of working change. A consistent, documented process puts organisations in a stronger position to keep engaging the independent professionals they rely on.
A separate consultation on employment status
The other thing to watch sits outside the Budget. On 14 October the government opened a consultation on employment status reform, which closes on 8 January 2027. Its proposals include revising the worker status test and, in relevant employment-rights enforcement or tribunal claims, shifting more of the evidential burden towards the engaging business.
The consultation covers employment-rights status, such as entitlement to holiday pay and the minimum wage. It doesn't cover tax, so it doesn't change IR35. That also means an IR35 determination doesn't settle someone's employment rights: they're separate questions. These are proposals, not law. If adopted, they could increase employment-rights risk where engagements aren't clearly documented and operated, so it's worth having someone in HR or legal follow the outcome.
The Budget funded compliance capacity, not reform
The government plans to recruit an additional 670 HMRC compliance officers, on top of its earlier commitment to 5,500 more by 2029-30. Measures to close the tax gap announced in this Parliament are expected to raise over £12 billion in 2029-30.
These resources aren't dedicated to IR35 or contractor engagement, and the Budget makes no IR35-specific commitment. But a broader focus on tax compliance adds to the value of clear records across your labour supply chain. If an enquiry does come, the real cost is often the time spent reconstructing engagement histories and closing gaps between contracts and day-to-day practice. A documented process won't guarantee HMRC agrees with every outcome, but it's a far stronger starting point than piecing evidence together after the fact. Our guide to what to expect from an HMRC IR35 compliance check covers the practical side.
Finance teams will also want to note two planned changes to tax collection. The government plans to require a direct debit instruction for VAT liabilities from 1 April 2029 and for PAYE liabilities from 6 April 2029. Other payment methods are expected to remain available before a cut-off, after which the direct debit would collect any unpaid balance. It also plans to give HMRC a new power, from July 2029, to recover lower-value tax debts directly from the bank accounts of individuals and companies who can afford to pay but repeatedly don't. Both are proposals for now, so they're points for cash-flow planning and payment controls rather than current obligations.
Umbrella supply chains: what's live and what's planned
Umbrella companies barely feature in the Budget, mostly because the significant change has already happened. Since 6 April 2026, where an umbrella company fails to account correctly for PAYE, HMRC can recover the relevant unpaid amounts from another party in the supply chain. That's often the agency contracting directly with the end client. The end client can be liable only in specified cases, such as where there's no agency. HMRC's guidance on the April 2026 rules sets out how liability is allocated, and we covered the background in HMRC's new umbrella rules.
Regulating umbrella companies is a separate reform. The government intends to bring them within employment agency regulation under the Employment Rights Act, and its current implementation timetable, updated on 22 October, puts that in December 2027, subject to implementing regulations and further change.
The Budget added one related signal. The government plans to consult on measures to tackle both the promotion and the use of tax avoidance. The scope isn't settled and the consultation doesn't create new obligations, but the proposed focus on users as well as promoters is relevant to anyone relying on intermediaries to engage and pay workers. An arrangement offering unusually high take-home pay, unexplained deductions, or a margin that looks too thin to cover compliant employment costs is worth a closer look.
In practice, the checks are the same as they were in April. Know who employs and pays each worker in your supply chain, understand the payment model, and keep a record of how each supplier was checked. Accreditation is useful due diligence, but it isn't a statutory safe harbour or a substitute for ongoing oversight.
Workforce costs: what to plan for
National Living Wage. From 1 April 2027, the National Living Wage rises 3.9% to £13.21 an hour for workers aged 21 and over, and the rate for 18 to 20-year-olds rises to £11.27. Entitlement depends on someone's legal status rather than their job title, so these rates don't apply to genuinely self-employed contractors. For lower-paid agency and umbrella workers, the rise may feed into assignment rates, depending on how your contracts handle employment costs.
Employer National Insurance. The Budget didn't announce a change to the headline employer rate. For 2026-27, the standard employer rate is 15%, subject to thresholds and category-specific exceptions, with a secondary threshold of £5,000 a year. Last year's Budget set out a freeze on that threshold until April 2031.
Visa sponsorship costs. The Budget announced a tax exemption, pending legislation, for employers paying the Immigration Skills Charge or Certificate of Sponsorship fees in relevant Skilled Worker cases, for payments made on or after 28 October 2026. It doesn't extend to sponsor licence fees, visa fees or the Immigration Health Surcharge.
Other developments to monitor
Non-compete clauses. The government intends to legislate to limit non-compete clauses and plans to consult on wider restrictive practices. Scope and timing aren't settled, so existing restrictions haven't become unenforceable, and it isn't yet clear whether contractor terms will be covered.
Parental support for the self-employed. The government plans a new parental allowance from April 2029 for eligible self-employed fathers, partners and adopters in Great Britain.
VAT e-invoicing. From 1 April 2029, the government plans to require structured e-invoicing where a UK VAT invoice is required, subject to exemptions and final technical requirements. Finance teams processing contractor and supplier invoices will want to follow the design as it develops.
The takeaway for 2027
The Budget doesn't itself change the off-payroll working rules, and it doesn't change the case for engaging independent talent. What it adds is more compliance capacity and a set of planned reforms, which makes it worth keeping your status determinations, working-practices evidence and supply-chain controls under review.
Five checks are worth prioritising before April:
- Confirm where you sit. If you're close to the small-company limits, check whether, and from when, your responsibilities under the off-payroll working rules change.
- Determinations match the work. Where the rules require an SDS, check it still reflects how each engagement actually runs, and reassess where things have changed.
- Your umbrella supply chain is mapped. Know who employs and pays each worker, how they're paid, and how each supplier was checked.
- Budgets reflect April 2027. Factor the National Living Wage rise into costs for lower-paid agency and umbrella workers.
- The status consultation is on someone's desk. It closes on 8 January 2027. Even if you don't respond, someone in HR or legal should know what's proposed.
