Travel Expenses Tax Relief for UK Employees

You can claim tax relief on travel costs you pay yourself for journeys to temporary workplaces. HMRC does not give relief for ordinary commuting.

The relief reduces the income tax you owe, based on the rate you pay. You can backdate claims for up to four previous tax years.

A higher-rate taxpayer driving 8,000 unreimbursed business miles could claim back £1,760 in one year. HMRC does not apply this relief automatically. You have to claim it.

The relief exists because HMRC draws a firm line between ordinary commuting and business travel. Getting to a permanent workplace is your own cost. Travelling to a temporary one is a cost of doing the job.

HMRC only grants travel expenses tax relief on journeys that meet strict eligibility rules. Trips to client sites and temporary project locations qualify, but your regular commute does not.

The value of your travel expenses tax relief depends on the rate you pay.

Basic-rate taxpayers receive 20%, while higher and additional rates bring more.

Scotland operates different income tax bands affecting travel tax relief UK workers receive. Scottish taxpayers at intermediate or higher rates get a different percentage.

This guide explains which journeys qualify for travel expenses tax relief. It covers claim methods, evidence rules, and how to recover relief from earlier years.

Understanding travel expenses tax relief could save you hundreds of pounds. The four-year backdating window means past overpayments may be recoverable.

Travel Expenses Tax Relief Explained

Not every work journey counts toward tax relief on travel expenses. HMRC travel expenses rules draw a firm line between ordinary commuting and business travel.

Ordinary commuting HMRC defines as travel between home and a permanent workplace. Business travel tax relief covers journeys made in the performance of your duties.

Travel to a temporary workplace also counts if the expected stay is under 24 months. Site-based employee travel expenses arise most often in this category.

Employee travel expenses tax relief goes beyond fuel and fares. The following costs may also qualify:

• Train, bus, and taxi fares for qualifying business journeys.
• Parking fees, road tolls, and congestion charges during work travel.
• Accommodation and meal costs for overnight stays required by work.
• Mileage at HMRC approved mileage rates for your own car, van, motorcycle, or bicycle.

Each cost must be wholly and exclusively for business purposes. You must also have paid income tax in the year you are claiming for.

HMRC rejects claims that fall outside these rules. Common reasons for invalid claims include:

• Your daily commute to a permanent workplace, however long or expensive.
• Food brought from home when travelling to a temporary workplace.
• Expenses your employer has already reimbursed in full tax-free.
• Lunch costs incurred travelling to your normal place of work.

Submitting an invalid claim can lead to HMRC requesting repayment. Checking eligibility before you submit avoids delays and potential penalties.

Temporary Workplace Tax Relief Rules

Whether a workplace is temporary or permanent determines your temporary workplace tax relief eligibility. HMRC applies two tests to make that distinction.

The 24 month rule HMRC applies treats a workplace as permanent once attendance exceeds 24 continuous months. After that point, travel there becomes ordinary commuting.

The 40% rule temporary workplace test adds a second condition. HMRC only classifies a site as permanent if you spend over 40% of your working time there.

Both tests must apply at the same time. Attending a site for 30 months while spending only 20% of your hours there may keep it temporary.

Fixed-term contracts create a complication. A contract covering your entire attendance at one site lets HMRC treat it as permanent from day one.

Construction workers, engineers, and IT contractors move between projects frequently. Each new site is typically a travel to temporary workplace under these rules.

Monitoring these thresholds is your responsibility. Once a site crosses into permanent status, relief on future journeys stops immediately.

HMRC Approved Mileage Rates

Employees who use their own vehicle for business travel qualify for approved mileage allowance payments. These flat amounts cover fuel, wear, and insurance in one figure.

The rates for the 2026/27 tax year are as follows:

• Cars and vans: 55p per mile for the first 10,000 business miles, then 25p after that.
• Motorcycles: 24p per mile with no upper mileage threshold.
• Bicycles: 20p per mile with no upper mileage threshold.

The previous rate of 45p per mile tax relief applied from 2011 until the increase to 55p. Check the current tax year to confirm the rate that applies to your claim.

If your employer pays below the approved rate, you can claim mileage tax back on the shortfall. A business mileage tax rebate covers the gap between what you received and the HMRC rate.

Carrying a colleague on a business journey lets you claim an extra 5p per mile per passenger. This payment is separate from the standard mileage rate.

At 20%, a basic-rate taxpayer with 5,000 unreimbursed miles receives £550 in mileage allowance relief. The same claim at 40% produces £1,100 for a higher-rate taxpayer.

Subsistence Tax Relief and Accommodation

Mileage is not the only claimable cost. Several other work travel expenses UK employees can claim back arise during business journeys.

Subsistence tax relief covers food and drink bought while working away from your normal base. Only meals purchased during the trip count, not food from home.

Accommodation expenses tax relief applies when work requires an overnight stay. Hotel costs and similar lodging qualify if the stay is necessary for business.

Parking fees tax relief covers charges at or near a temporary workplace. Toll charges tax relief and congestion charge tax relief apply on qualifying journeys too.

Tax relief on public transport extends to trains, buses, and taxis for eligible work travel. Claim back travel costs by keeping dated receipts showing the provider and amount.

A travel and subsistence allowance from your employer reduces what you can claim. Relief applies only to the portion you paid and have not been repaid.

When Your Employer Pays Part of the Cost

Many employees receive some travel payment from their employer. The reimbursement amount directly affects your eligibility for a travel expenses tax rebate.

Full reimbursement at or above the approved rate leaves nothing further to claim. That payment is tax-free up to the approved limit.

Partial reimbursement is far more common. An employer not reimbursing travel expenses in full creates a gap you can reclaim through HMRC.

Some employers pay a travel allowance that is taxed through payroll alongside your salary. You have already paid tax on that amount, so you can claim relief from HMRC at the same approved rates.

Here is a combined worked example showing how multiple expense types add up:

• A site-based engineer drives 6,000 business miles and receives 25p per mile from their employer (£1,500 total).
• The HMRC approved rate for those miles is 55p, totalling £3,300 — a mileage shortfall of £1,800.
• The engineer also pays £320 in parking fees and £180 in subsistence that the employer does not reimburse.
• The total claimable amount is £2,300 (£1,800 mileage plus £320 parking plus £180 meals).

A 20% basic-rate taxpayer receives £460 in tax relief on that £2,300 claim. The same claim at 40% produces a travel expenses tax refund of £920.

Reimbursement above the approved rate counts as taxable income. Check your payslips each month to spot any underpayment or excess.

Records and Evidence HMRC Expects

A successful travel expenses claim depends on good records. Travel expenses records HMRC expects can be requested at any stage.

Keeping travel expenses evidence HMRC may ask for organised and accessible saves time. For each expense type, keep the following:

• Mileage: a mileage log with dates, start and end postcodes, trip purpose, and miles driven.
• Subsistence and accommodation: dated receipts showing the provider name and amount paid.
• Parking, tolls, and congestion charges: individual payment receipts or statements for each charge.
• Employer details: your contract or a letter confirming the temporary nature of your workplace.

A mileage tracking app can simplify evidence collection significantly. Apps log your start point, destination, and distance automatically using GPS.

Some apps also let you photograph receipts and store them alongside journey records. This creates a single digital file ready for HMRC if requested.

Organise all records by tax year. HMRC accepts claims going back four years, so documents may need to span multiple periods.

Claiming without records is possible but significantly harder. HMRC may ask you to explain your circumstances before reaching a decision.

Claiming Travel Expenses From HMRC

Three routes exist for a travel expenses claim from HMRC. The choice depends on claim size and whether you file a self-assessment tax return.

Each route has its own threshold and process:

1. iForm online (under £2,500): access the iForm through your Personal Tax Account on the Government Gateway and upload evidence digitally.
2. P87 form travel expenses (under £2,500): the P87 form is for those who prefer a paper submission.
3. Self-assessment (over £2,500): list your travel expenses self assessment costs in the employment section of your return.

The iForm is the fastest method for employment expenses tax relief claims. HMRC processes online submissions more quickly than postal ones.

If posting a P87, keep copies of everything you send. Proof of postage protects you if the form goes astray.

If you do not already file a return, register using an SA1 form. HMRC then creates an account so you can submit.

How to claim travel tax relief for travel expenses previous tax years follows the same methods. HMRC accepts backdated claims for up to four years.

Current-year claims result in a tax code adjustment. Previous-year claims produce a refund — check your tax code after any change in your travel pattern. If you stop travelling or change jobs, the old relief may remain in your code.

An outdated code means you pay too little tax during the year. HMRC then recovers the difference, which can come as an unexpected bill.

Hybrid and Site-Based Employee Travel

Hybrid working travel expenses raise specific questions for modern employees. Splitting time between home and an office may create two permanent workplaces.

Days you travel to the office count as ordinary commuting. Home-based work relief does not turn your home into a workplace for travel purposes.

Travelling to a client meeting or different office from home may still qualify. Whether the destination counts as a temporary workplace is the deciding factor.

Site-based employee travel expenses follow clearer lines. Construction workers, IT staff, and engineers moving between projects can claim for each location.

Each site counts as temporary if the expected duration stays under 24 months. You must also spend less than 40% of your working time there.

Agency workers face additional restrictions. Check arrangements with your intermediary before submitting — HMRC’s travel expenses guidance covers the latest rules.

The rules around claim travel expenses HMRC applies can be complex for non-standard arrangements. Reviewing your contract alongside official guidance is a sensible step.

Employees who hold two or more jobs may also qualify. Travel between one employer’s workplace and another’s can count as a business journey for tax relief purposes.

Claim Your Travel Expenses Tax Relief

Travel expenses tax relief is available to most employees who pay for qualifying work journeys. The process covers employment expenses of several types, from mileage to meals.

Check whether your workplace counts as temporary under the 24-month and 40% rules. Confirm what your employer has reimbursed and calculate the shortfall.

Gather your evidence and choose the right claim route. You can recover money from up to four previous tax years.

Basic-rate, higher-rate, additional-rate, and Scottish taxpayers each receive relief at their own band. The value depends on how much you spent and which rate applies.

Start by checking eligibility, then submit through the iForm, P87, or self-assessment. Every qualifying journey you paid for is a potential reduction in your tax bill.

Key Takeaways

The following points summarise the essentials of claiming travel expenses:

• Tax relief applies to travel to temporary workplaces, not your daily commute to a permanent one.
• HMRC approved mileage rates for 2026/27 are 55p per mile for the first 10,000 miles and 25p after that.
• The 24-month rule and 40% rule together decide whether a workplace is temporary or permanent.
• Claims under £2,500 go through the iForm or P87; claims over £2,500 need a self-assessment return.
• You can backdate claims for up to four previous tax years and receive refunds by cheque or bank transfer.
• Keep a mileage log with dates, destinations, postcodes, and trip purposes, plus dated receipts for other costs.

Each point applies to employees who fund qualifying journeys and have not been fully reimbursed.

Common Travel Expenses Tax Relief Questions

These questions cover edge cases and common misconceptions that fall outside the main guide above.

Can I claim for a journey the same distance as my normal commute?

Ordinary commuting covers more than just your usual route. A journey to a temporary workplace matching your regular commute in time and cost may not qualify.

HMRC may treat it as ordinary commuting if the trip is not genuinely different. Your destination must represent a distinct journey to succeed.

Do electric vehicle owners get different mileage rates?

Employees using their own electric car claim at the standard 55p and 25p AMAP rates. No separate EV rate exists for personal vehicles.

Company electric cars use advisory electricity rates instead. These are 7p per mile for home charging and 15p for public charging as of 2026.

Do I get the full expense amount back from HMRC?

Tax relief reduces the income you are taxed on, not the tax itself pound for pound. You receive back only the tax percentage of the qualifying amount.

A £1,000 claim at 20% basic rate produces a £200 saving. The same amount claimed at 40% returns £400.

Can I claim after leaving the job where I incurred travel costs?

Leaving a role does not cancel your right to claim. The four-year limit runs from the end of the tax year the expense fell in.

Your former employer’s PAYE reference number is needed for the form. It appears on your P45 or P60 from that employment.

Are congestion charges and tolls treated differently from mileage?

Congestion charge and toll charge relief are separate from mileage claims. You claim the actual amounts paid, not a per-mile rate.

Individual receipts or payment records are required for each charge. HMRC treats them as travel expenses under the same temporary workplace rules.
