Budget 2026 Tax Changes: What Sole Traders Actually Face

Budget 2026 lands on Wednesday 28 October 2026, and if you are a sole trader you have probably already seen the headlines guessing at what it will contain. Most of that coverage blurs two very different things: the changes that are already law or already announced, and the rumours about what the Chancellor might add on the day. This guide separates them. It sets out what is already locked in for the self-employed, what is genuinely in play on 28 October, and what you should do this week regardless of what is announced.

What we know about Budget 2026 so far

The date was confirmed by the Chancellor, John Healey, earlier this year, and the Office for Budget Responsibility will publish its economic and fiscal forecast alongside the statement. HMRC opened its Budget 2026 tax documents page on 26 October, but every section of it is empty until the speech is delivered.

“Full details of all announcements, supporting documents and information will be available on 28 October 2026.”

That matters, because a lot of what is circulating as "Budget 2026 tax changes" is really one of three things:

1. Measures announced at the November 2025 Budget that start in 2026 or 2027.
2. Long-running policy such as Making Tax Digital that has nothing to do with this week's statement.
3. Speculation from commentators about where the Treasury might find money.

We will update this page once the Budget documents are published on 28 October, with what actually changed for sole traders.

What is already locked in for sole traders

These changes were announced before this Budget and are already in force or legislated for. None of them depend on what the Chancellor says on Wednesday.

The freeze is the change that costs the most

A frozen threshold is a tax rise that never gets announced as one. The Personal Allowance has been £12,570 since April 2021, and the November 2025 Budget extended the freeze by three more years to April 2031. Over that decade, prices have risen sharply, so a sole trader whose profit has merely kept pace with inflation is now paying tax on more of it, and is more likely to cross the £50,270 line into the higher rate.

Fiscal drag

The effect of inflation pushing taxpayers into higher tax bands when allowances and thresholds are not raised in line with prices. More tax is collected without any change to the headline rates, which is why a frozen threshold works like a quiet tax rise.

For a sole trader with £65,000 of profit, the slice between £50,270 and £65,000 is taxed at 40% income tax plus 2% Class 4 National Insurance, a marginal rate of 42% on £14,730. If your profit is between £60,000 and £80,000 and you claim Child Benefit, the High Income Child Benefit Charge adds to that, because it is calculated on adjusted net income. You can see the effect on your own numbers with our take-home tax calculator.

If you also let property

Many sole traders also have a rental property, and that income is about to be taxed differently. From 6 April 2027, property income in England, Wales and Northern Ireland gets its own set of rates: 22%, 42% and 47%, two points above the rates on your trading profit. Relief for mortgage interest and other finance costs moves to 22% at the same time, so the tax reduction on those costs rises in step with the basic rate. Your business turnover and your gross rent also count together towards the MTD threshold, which is based on income before expenses, so a sole trader with £22,000 of turnover and £10,000 of rent is over £30,000 and comes into MTD in April 2027.

Making Tax Digital is live, not coming

If your qualifying self-employment and property income was over £50,000 in 2024/25, Making Tax Digital for Income Tax has applied to you since 6 April 2026. That means keeping digital records, sending a quarterly update to HMRC through recognised software, and filing a final declaration after the year ends instead of a traditional Self Assessment return.

The quarterly deadlines for the 2026/27 tax year are fixed:

The Q2 update is due ten days after the Budget. Whatever is announced on 28 October, it will not change the figures you report for July to October, because a quarterly update is a summary of your income and expenses, not a tax calculation you are locking in. HMRC has said it will not issue penalty points for late quarterly updates during 2026/27, the first year of the regime, but the update is still required, and points-based penalties apply from 2027/28. Our step-by-step quarterly submissions guide walks through what goes into each one, and the full calendar is in our MTD deadlines for 2026, 2027 and 2028 guide.

If your income is between £30,000 and £50,000, the Budget is a good reminder that your turn comes in April 2027. HMRC will use your 2025/26 return, the one due by 31 January 2027, to decide whether you are in scope, so the figures you are finalising now are the ones that count.

What is genuinely in play on 28 October

Nothing below has been announced. These are the areas commentators and accountancy firms expect the Treasury to look at, and they are listed so you know what to watch for, not because any of them is confirmed.

• Thresholds and allowances. The manifesto pledge covers the rates of income tax, employee National Insurance and VAT, but not the thresholds, so further freezes or changes to allowances remain possible.
• Self-employed National Insurance. Class 4 National Insurance is not covered by the pledge in the same way as employee contributions, and it is regularly raised in pre-Budget speculation.
• The VAT registration threshold. It has been £90,000 since April 2024. Any change to it would matter to sole traders near that level.
• Dividends, savings, property and capital gains. These sit outside the pledge and have already been targeted once, so they are the most frequently tipped for further change.
• Making Tax Digital. The rollout dates are set, but Budgets have adjusted MTD details before, for example on which taxpayers are exempt.

The honest position is that nobody outside the Treasury knows which of these, if any, will move. Planning around a rumour is riskier than waiting two days for the documents.

What to do before and after the Budget

Get your Q2 records straight now. The 7 November deadline does not move, and the work is the same whatever the Chancellor announces. Make sure every income and expense transaction from 6 July to 5 October 2026 is recorded and categorised.

Do not make big decisions on a rumour. Bringing forward income, buying equipment early or changing how you pay yourself in anticipation of a change that may never come can cost you more than it saves. Wait for the documents on 28 October.

Check whether you are close to a threshold. If your profit is near £50,270, £60,000 or £100,000, or your turnover is near the £90,000 VAT threshold, those are the lines where a Budget change, or the existing freeze, hits hardest. Pension contributions remain one of the most effective ways to bring adjusted net income back below a threshold.

Read the announcements, not the coverage. HMRC publishes a policy paper for every tax measure. If something applies to you, the paper says exactly who it affects and from when.

Why we are not guessing

There is a temptation every Budget week to publish confident lists of what is about to change. For a business filing to HMRC, that is the wrong instinct. The changes that will actually affect your 2026/27 tax bill are mostly the ones already set out above, and the rest will be public in two days. We will update this guide on 28 October with what Budget 2026 really means for sole traders, and anything that changes how TapTax calculates your estimate will be reflected in the app.
