The tax, pension and savings changes UK contractors need to keep on top of

The 2026/27 tax year might not be bringing one dramatic overhaul, but it marks the beginning of a multi-year shift that will reshape how contractors, freelancers and limited company directors manage their money.

We’ve already had the introduction of Making Tax Digital. And with ISA reforms and future restrictions on salary sacrifice, the direction is clear: more tax exposure, fewer easy wins, and a greater need for proactive planning.

Here’s a breakdown of the most important changes for contractors and what they mean in practice.

Disclaimer: The following is an informational overview of planned changes, correct as of the date of writing (June 2026). Always seek professional advice in relation to your own finances and how any changes might impact you.

1. ISA changes bring less flexibility

Whether it’s putting aside money for the taxman or stockpiling a buffer to cover bills in quieter months, it’s no secret that cash ISAs are a go-to solution for contractors.

But a wave of changes to tax-free savings is coming, including a decrease in the amount you can save in a cash ISA from 2027.

The ISA limit in 2026-2027

As it stands in 2026, the ISA allowance remains £20,000. Of course, this can be split across cash and investment ISAs, with all returns remaining free from income tax, dividend tax and capital gains tax.

Cash ISA limit cut from April 2027

The date for your diary is 6 April 2027, when the major cash ISA change will take effect:

• Cash ISA-specific contributions will be capped at £12,000 (for savers under 65yrs)
• The £20,000 total allowance across ISAs remains – the other £8,000 must be saved in a different kind of ISA e.g. stocks and shares

What ISA changes mean for contractors

If you’re a contractor using a cash ISA to store emergency funds or put aside money for your tax payments, this reform nudges you towards investment savings like a stocks and shares ISA.

There’s no hiding that this change may bring with it:

• More complexity – more account types to track finances for
• More risks – investment markets are volatile with no guaranteed return
• Less short-term flexibility – withdrawing at the wrong time could lock in losses

Bottom line:

Cash ISAs remain essential, but less useful for purely “safe” savings from 2027. Best advice: make the most of the current £20k limit while you can in 2026/2027.

2. Mileage claims: a rare 2026 boost

In one of the few ‘welcome’ changes for the self-employed, HMRC has increased mileage rates for the first time in 15 years.

Estimated to benefit 1 million self-employed workers, the changes could save £120 a year for someone who drives 6,000 miles, as an example.

New mileage rates (from April 2026)

Applying to Approved Mileage Allowance Payments (AMAPs), Mileage Allowance Relief (MAR) and self-employed mileage, the new rates are:

• 55p per mile for the first 10,000 miles (up from 45p per mile)
• 25p for ever mile over 10,000

Even better, this change can be backdated to 6^th April 2026, applying to the whole 2026/2027 tax year!

3. Big changes coming to salary sacrifice pensions

For umbrella contactors and limited company contractors working ‘inside IR35’ engagements, pension salary sacrifice is a tax-efficient way to make your money work harder. But big changes are coming that will impact anyone enjoying the benefits.

What is pension salary sacrifice?

For those new to the world of salary sacrifice for pensions, it’s a contractual agreement to ‘sacrifice’ part of your gross salary, with your employer paying it into your pension instead. This reduces the leftover taxable income and you pay less tax and national insurance contributions (NICs) as a result.

The new £2,000 NICs cap from 2029

The government has announced a major restriction, limiting the savings benefits of the salary sacrifice scheme from 2029. What you need to know:

• Effective from April 2029
• Only the first £2,000/year of employee pension contributions via salary sacrifice will be exempt from NICs
• Contributions above this will be subject to employee and employer NICs
• All salary sacrifice contributions will remain exempt from tax (subject to your usual limits)

Bottom line:
Salary sacrifice isn’t disappearing, but its biggest advantage is being dampened.

4. Tax thresholds frozen in time

Not all tax changes arrive with big announcements or obvious headline impacts. In fact, some of the most significant financial pressures facing contractors today are happening quietly, through small adjustments that stack up over time.

Income tax thresholds frozen until 2031

While not a ‘leading story’, the frozen thresholds have brought in a “stealth tax”– invisible if you look too close and only noticeable if you look at the bigger picture over a couple of years.

The thresholds (as of 2026):

• Personal allowance: £12,570
• Higher rate threshold: £50,270

In the Spring Budget 2021, the then Chancellor Rishi Sunak announced that these thresholds would be frozen until 2026. This freeze has since been extended multiple times, most recently by Rachel Reeves in the 2025 Autumn Budget. Now the freeze is set to be in place until 2031.

Why this matters – “fiscal drag”

It might not seem like that big of a change, but it’s a silent killer. What happens is:

• Your salary increases with inflation
• The thresholds stay the same
• More of your income is above the frozen thresholds
• You pay tax on more of your income
• You could eventually be pushed into a higher tax band

Bottom line:

Even without headline tax hikes, contractors are paying more each year just because they increase their salary so it remains liveable.

The big picture: a quiet squeeze on contractors

Individually, these changes might seem manageable – but together they show a clear trend.

A tweak to cash ISA limits here, a frozen threshold there, a limit added somewhere else. But when you step back and look at the bigger picture, a pattern starts to emerge. Bit by bit, contractors are being asked to pay more tax, take on more risk, and save with less flexibility than before.

It’s not a sudden hit – it’s a slow squeeze.

And unless you’re actively planning around it, it can quietly eat into your income year after year.

What contractors should do now

It’s not all doom and gloom – the early bird catches the worm, so they say. Getting ahead of changes is a contractor’s best defence, and thankfully a lot of the above won’t be for a while yet.

• Maximise ISAs now – Use full £20,000 allowance before April 2027 and reassess your long-term savings and investment strategy.
• Review pension approach – Use salary sacrifice while still fully effective, but plan for post-2029 changes.
• Remember to claim all expenses – Update mileage logs to reflect 55p rate and make sure nothing’s missed.
• Plan for higher tax and NICs – Stress-test income vs rising tax burden and consider the best way to get more from your money so you’re prepared for any increases in your tax bill.
