If you are self-employed, the October 2026 Budget is actually quite interesting.

Not quit-your-job-and-celebrate interesting.

But there are some genuinely useful changes.

The headline for freelancers is:

small side businesses get simpler, business mileage gets more generous, but Making Tax Digital is about to pull a lot more sole traders into quarterly reporting.

So let's skip the political commentary and look at what actually changes.

The Trading Allowance is jumping from £1,000 to £3,000

This is probably the most immediately useful announcement for people with smaller side businesses.

From 6 April 2027, the Trading Allowance increases from:

£1,000 → £3,000

The Self Assessment reporting threshold for relevant trading income will also increase to £3,000.

That matters to people earning modest amounts from things like:

  • freelance work;
  • tutoring;
  • photography;
  • design;
  • consulting;
  • content creation;
  • online services;
  • occasional contracting;
  • craft businesses; or
  • other side hustles.

Under the new rules, somebody whose relevant gross trading income is covered entirely by the £3,000 allowance may no longer need to declare or pay Income Tax on that income, subject to the detailed rules.

That is a meaningful simplification.

Especially for someone earning £1,500 or £2,000 from a small side business who previously found themselves dealing with Self Assessment for relatively little income.

But £3,000 does not mean every freelancer gets £3,000 tax-free on top of expenses

This is the important bit.

The Trading Allowance is generally an alternative to claiming actual business expenses.

You do not normally get to say:

£3,000 Trading Allowance + laptop + phone + travel + software + all my other expenses please.

You choose the appropriate method.

For example:

You earn £8,000 from freelance work.

Your actual allowable business expenses are £1,000.

Using the £3,000 Trading Allowance may potentially give you a better deduction than claiming the £1,000 of actual expenses.

But imagine instead that your expenses are £4,500.

In that situation, claiming your actual allowable expenses may be more beneficial.

So the new £3,000 allowance is useful.

It is not automatically the right choice.

Side hustle does not mean invisible to HMRC

There is another misconception worth clearing up.

The Trading Allowance is not a new:

"HMRC doesn't need to know what I do online" allowance.

Digital platforms are already providing more information to tax authorities.

Banks, marketplaces and accounting software are increasingly part of the wider data picture too.

The sensible approach is still:

keep records of what you earn.

Even where the Trading Allowance means no tax is ultimately payable.

Because if HMRC ever asks where the numbers came from, "I think it was about £2,500" is less persuasive than an actual record.

Business mileage gets more generous

This is a nice one for self-employed people who use their own car or van for work.

The simplified mileage rate for the first 10,000 business miles was increased to 55p per mile from April 2026, and Budget 2026 confirms that higher rate permanently.

From 6 April 2027, the rate for mileage above 10,000 miles also increases:

25p → 35p per mile

This matters particularly to:

  • mobile consultants;
  • tradespeople;
  • photographers;
  • carers;
  • tutors;
  • contractors;
  • therapists;
  • trainers; and
  • anyone travelling regularly between customers.

A quick example

Imagine you drive 12,000 qualifying business miles in a year.

Under the current structure:

  • first 10,000 miles × 55p = £5,500
  • next 2,000 miles × 25p = £500

Total mileage deduction:

£6,000

From April 2027:

  • first 10,000 miles × 55p = £5,500
  • next 2,000 miles × 35p = £700

Total:

£6,200

An extra £200 deduction.

Not life-changing.

But if you're driving the miles anyway, you might as well claim the correct amount.

Mileage is not the same as being paid 55p by HMRC

Another important distinction.

If you are self-employed and using simplified mileage, the mileage rate is generally a way of calculating an allowable business deduction.

HMRC does not send you 55p every time you drive a mile.

If your allowable deduction increases by £200, that does not mean £200 lands in your bank account.

It reduces the profit on which tax is calculated.

Small distinction.

Quite important distinction.

Fuel duty is also staying lower for longer

The temporary 5p-per-litre fuel-duty cut has been extended until 1 July 2027.

For freelancers who drive frequently for work, that provides some additional breathing room.

But remember:

if you use simplified mileage for your vehicle costs, the mileage rate is designed to cover vehicle running costs.

You cannot generally claim simplified mileage and then separately add the same fuel costs again.

No double dipping.

HMRC tends to be rather unsentimental about that sort of thing.

Income Tax rates are not changing dramatically

For 2027/28, the main Income Tax rates remain:

  • 20%
  • 40%
  • 45%

The standard Personal Allowance remains £12,570.

So there is no dramatic new headline Income Tax increase on ordinary self-employed trading profits.

That is the good news.

The less exciting news is that frozen tax thresholds mean your income can rise while the thresholds do not.

In other words:

you can earn more without necessarily feeling much richer, while more of that income moves into higher tax bands.

This is sometimes called fiscal drag.

A slightly technical phrase for:

"Congratulations on the pay rise. HMRC would also like one."

The much bigger issue for many freelancers is Making Tax Digital

This is not a surprise announcement from this week's Budget.

But for freelancers planning 2027, it is arguably more important than most of the Budget headlines.

Making Tax Digital for Income Tax is already live for the first group of sole traders and landlords.

From 6 April 2027, it expands again.

If your qualifying self-employment and property income exceeded £30,000 in the 2025/26 tax year, you will generally need to use Making Tax Digital for Income Tax from April 2027, unless an exemption applies.

From April 2028, the threshold falls again to more than £20,000, based on qualifying income in 2026/27.

That means a lot more freelancers are about to move from:

one tax return each year

to:

digital records + compatible software + quarterly updates + an annual tax return process.

The £3,000 Trading Allowance does not change the MTD threshold to £3,000

These two announcements should not be confused.

The new £3,000 Trading Allowance is about relief and Self Assessment reporting for relatively small amounts of trading income.

Making Tax Digital has its own qualifying-income thresholds.

For April 2027, the relevant MTD threshold is still more than £30,000.

So:

£3,000 Trading Allowance ≠ £3,000 MTD threshold.

Different rules.

Different purposes.

Because apparently one tax threshold would have been too straightforward.

What does MTD actually mean for a freelancer?

It does not mean preparing four complete tax returns every year.

Quarterly updates are summaries created from your digital accounting records.

But it does mean your records need to be much more current.

For many freelancers, that changes the old bookkeeping routine of:

January 12th: find twelve months of bank statements.

January 13th: regret every life decision that led here.

January 20th: send accountant spreadsheet called FINAL-v7-USE-THIS-ONE.xlsx.

MTD pushes the process towards bookkeeping throughout the year.

And while that may initially feel like more administration, there is a business benefit.

If your records are current, you can actually see:

  • how much profit you are making;
  • how much tax to reserve;
  • which clients are profitable;
  • whether expenses are increasing;
  • whether you can afford a purchase;
  • whether pricing needs to change; and
  • what cash you genuinely have available.

That is much more useful than discovering the answer nine months after the year ended.

What if you freelance alongside a salary?

This is where people often get confused.

Having a PAYE salary does not stop you being self-employed.

Imagine you earn:

£45,000 salary

plus

£12,000 freelance income.

The freelance business still needs to be considered separately.

The new Trading Allowance may affect how some smaller amounts of trading income are reported.

But your salary and freelance profit ultimately interact when your overall Income Tax position is calculated.

So a side business should not be treated as existing in a separate tax universe.

Your accountant needs the full picture.

Does the Budget make being a sole trader better than using a limited company?

Not automatically.

The Trading Allowance increase makes things simpler for small trading activities.

It does not suddenly make sole trader status the best structure for every established consultant.

Once your business becomes more profitable, you still need to consider questions such as:

  • How much profit does the business make?
  • How much do you need personally?
  • Can profits remain in the business?
  • How much commercial risk do you carry?
  • Do your customers expect a limited company?
  • Are you hiring?
  • Are you building something that could eventually be sold?
  • Could IR35 or off-payroll rules be relevant?

A £3,000 Trading Allowance is lovely.

It should probably not determine the legal structure of a £120,000 consultancy.

One longer-term win for self-employed parents

There was also a change that will not arrive immediately but is worth noting.

From April 2029, eligible self-employed fathers, partners and adopters in Great Britain are due to gain access to parental pay.

Currently, self-employed fathers and partners can fall through a gap in the system compared with employees.

The government says the new measure should extend support to more than 150,000 additional parents each year.

It is some way off.

But for once, "self-employed" is becoming slightly less synonymous with:

"Congratulations on the baby. See you back at work on Monday."

So who actually benefits from this Budget?

Very small side hustles

Probably the clearest winners.

The increase in the Trading Allowance to £3,000 can remove tax and reporting requirements for some genuinely small activities.

Freelancers who drive a lot

A modest win.

Higher mileage rates mean larger allowable deductions.

Established sole traders below the MTD threshold

Not much changes immediately.

But keep an eye on the April 2028 expansion.

Sole traders above £30,000 qualifying income

Your bigger issue is probably MTD from April 2027, not the Budget itself.

High-earning freelancers

The Budget does not dramatically change ordinary trading Income Tax rates.

But frozen thresholds and the wider tax position still make forward planning important.

What should freelancers do now?

Nothing dramatic.

But I would do five things.

Check your 2025/26 qualifying income

If it exceeded £30,000, find out whether MTD applies to you from April 2027.

Do not discover this in April.

Review your bookkeeping software

If MTD is approaching, now is a much better time to get comfortable with digital records than March 2027.

Check how you claim vehicle costs

If you use simplified mileage, make sure you are recording actual business miles.

Google Maps plus a vague memory six months later is not ideal bookkeeping.

Review the Trading Allowance next April

If your income is relatively small, compare:

£3,000 allowance

against

your actual allowable expenses.

Use whichever treatment is appropriate and more beneficial.

Keep a tax reserve

A bigger Trading Allowance does not mean tax has disappeared for established freelancers.

If you're earning meaningful profits, continue putting money aside.

Your January tax bill remains considerably less frightening when you have already saved for it.

The Solutio view

For freelancers, Budget 2026 is actually a reasonable example of why tax headlines need context.

£3,000 tax-free Trading Allowance!

Sounds huge.

For someone earning £2,000 from a side hustle?

It could be genuinely useful.

For a consultant earning £90,000?

It is barely relevant.

Higher mileage rates!

Great if you drive 20,000 business miles.

Completely irrelevant if your commute is:

bedroom → coffee machine → laptop.

This is why the useful question after any Budget is not:

"What changed?"

It is:

"Which changes actually apply to me?"

For many established freelancers, the most important planning point for 2027 remains Making Tax Digital.

And the businesses that handle that transition best will probably be the ones that stop thinking of bookkeeping as:

something HMRC makes me do

and start using it as:

information about whether my business is actually working.

Frequently asked questions

What is the Trading Allowance from April 2027?

Budget 2026 announced that the Income Tax Trading Allowance will increase from £1,000 to £3,000 from 6 April 2027.

The trading-income reporting threshold for Self Assessment will also increase to £3,000.

Does that mean I can earn £3,000 from a side hustle tax-free?

Potentially, where the Trading Allowance applies and covers all of your relevant trading or miscellaneous income.

There are detailed rules and exceptions, so it should not be treated as a universal £3,000 tax exemption for every type of income.

Can I claim the £3,000 Trading Allowance and all my business expenses?

Generally no.

If you claim the Trading Allowance against relevant income, you cannot normally deduct actual expenses against that same income as well.

For businesses with significant expenses, claiming actual allowable costs may be better.

What are the self-employed mileage rates?

For qualifying simplified mileage for cars and vans, the first 10,000 business miles are 55p per mile.

From 6 April 2027, mileage above 10,000 miles increases from 25p to 35p per mile.

When does Making Tax Digital start for freelancers earning over £30,000?

If your qualifying income exceeded £30,000 in 2025/26, you will generally need to use Making Tax Digital for Income Tax from 6 April 2027, unless an exemption applies.

What happens in April 2028?

The MTD qualifying-income threshold falls again to more than £20,000, based on qualifying income in the relevant earlier tax year.

Are Income Tax rates increasing for freelancers?

The main rates applicable to ordinary non-savings, non-property trading income remain 20%, 40% and 45% for 2027/28 in England, Wales and Northern Ireland, with separate Scottish Income Tax arrangements.

Should I become a limited company because of the Budget?

The Budget itself is not a reason to incorporate.

The decision should be based on your profit, personal income requirements, commercial risk, customers and future plans.

The bottom line

For freelancers, Budget 2026 is less dramatic than some of the headlines suggest.

But there are useful changes.

Small side businesses get a much larger Trading Allowance.

Business mileage becomes more generous.

Fuel support continues.

Self-employed parents eventually get better parental support.

And at the same time:

Making Tax Digital is about to expand to thousands more sole traders.

So the practical message for 2027 is fairly simple:

If the business is small, life gets a little easier.

If the business is established, the records need to get better.

And tomorrow's other Budget group?

Landlords.

They have rather more to talk about.
