As HMRC tax changes take effect in 2025, finance leaders across UK SMEs are reviewing their expense policies to ensure compliance, manage risk, and prepare for further digital transformation 

From updates on benefit-in-kind charges to digital recordkeeping expectations under Making Tax Digital (MTD), this year’s changes reflect HMRC’s growing focus on accuracy and automation.  

In this guide, we break down the key expense-related tax changes for 2025 and what they mean for finance managers, financial controllers, and CFOs – especially those managing mileage reimbursements, VAT claims, and compliance workflows.  

Key HMRC expense rule changes in 2025  

In 2025, HMRC introduced a few updates that affect business expense management, though many core rules remain consistent with 2024.   

The most relevant changes and points of note include:  

1. Mileage reimbursement rates remain unchanged  

Despite rising fuel and vehicle costs, HMRC’s mileage rates remain frozen for 2025: 

The approved rates are still:  

  • 45p per mile for the first 10,000 business miles 

  • 25p per mile thereafter 

  • 24p for motorcycles

  • 20p for bicycles  

Breakdown of HMRC Mileage RatesWhile this simplifies planning (no need to adjust your expense policy rates), it also means the allowance hasn’t kept up with inflation, a point of contention among tax professionals.   

For now, CFOs should continue using the 45p/25p mileage rates to reimburse employees tax-free.

Just remember: if you choose to pay above those rates to better cover employees’ costs, the excess is taxable for the employee and reportable to HMRC.  

Also, don’t forget about HMRC’s Advisory Fuel Rates (AFRs) if reimbursing fuel for company car users. These are updated quarterly and vary by engine size and fuel type.  

2. Updates to company vehicle benefits  

For the 2025-26 tax year, taxable benefit values for company-provided vehicles have increased slightly:  

For example, the flat benefit charge for a company van rose to £4,020 (up from £3,960 in 2024-25).

Similarly, the annual multiplier used to calculate tax on company car fuel benefit jumped to £28,200 (from £27,800).   

These inflation-based changes affect P11D reporting, not day-to-day reimbursed expenses, but finance teams should update payroll systems accordingly.  

3. Making Tax Digital (MTD) progression  

There are no new Making Tax Digital (MTD) mandates for 2025, but HMRC is reinforcing the importance of digital compliance:  

  • MTD for VAT is already mandatory  

  • MTD for Income Tax begins in April 2026 for some  

  • VAT penalties are increasing (late payment interest now 4% above base rate 

MTD-compliant business expense tracker apps like ExpenseIn create a clear digital trail from each expense to your accounting records, making VAT reporting easier and helping you stay audit-ready if HMRC ever reviews your claims. 

4. VAT and expense policy reminders  

HMRC continues to stress the importance of having valid VAT receipts for reclaiming input VAT:  

Are digital receipts still compliant with HMRC in 2025?  

Yes. HMRC fully accepts digital receipts (or e-receipts) in 2025, provided they are:  

  • Clear, legible, and complete (front and back if needed)  

  • Stored securely in a digital format (PDF, JPEG, etc.)  

  • Retained for the required period (usually 6 years 

HMRC Digital Receipt Compliance RequirementsDigital receipts do not need to be scanned into MTD software, but best practice is to attach them to the relevant transaction in your accounting or expense management system 

VAT on employee expenses: What’s reclaimable in 2025?  

The rules on reclaiming VAT on employee expenses haven’t changed in 2025, but HMRC is cracking down on non-compliance. 

VAT on Employee Expenses

Key things to remember:  

You can reclaim VAT on:  

  • Hotel bills  

  • Client meals (subject to the entertaining rules)  

  • Car hire  

  • Fuel (if not using the fuel scale charge)  

  • Office purchases  

You cannot reclaim VAT if:  

  • There is no VAT receipt  

  • You’re reimbursing via a flat rate allowance with no itemised invoice  

  • It’s a client entertainment expense (blocked input tax)  

Why finance teams are turning to ExpenseIn in 2025  

As HMRC places greater emphasis on documentation, digital records, and timely VAT compliance, many UK finance teams are turning to automated tools to manage the increasing complexity of expense reporting 

ExpenseIn is one solution being widely adopted in 2025, not just to save time, but to help finance teams ensure consistency, accuracy, and alignment with HMRC’s changing requirements.

1. Automated checks against internal policy  

ExpenseIn allows companies to set specific rules for expense submissions, covering things like:

  • Daily limits

  • Mileage rates

  • Receipt requirements

automated-policies-heroThe system flags anything outside of those rules, helping reduce manual oversight and avoid non-compliant claims slipping through.  

2. Simple digital capture and storage of receipts  

Employees can photograph receipts using the mobile app and submit them instantly.   

The images are stored securely and attached to the relevant claim, providing a clear audit trail that meets HMRC’s expectations for digital recordkeeping.

3. VAT recovery  

The platform supports VAT tracking by letting employees enter VAT amounts (or detecting them from scanned receipts). This makes it easier to see what can be reclaimed and to report those amounts accurately.   

For finance teams managing quarterly VAT submissions, that clarity helps reduce the risk of errors or missed reclaims.  

4. Integration with accounting systems  

ExpenseIn integrates with platforms like Xero, Sage, and AccountsIQ.

This also helps avoid data duplication or transcription errors.  

5. Adapting to rule changes  

When HMRC updates Advisory Fuel Rates or expense thresholds, keeping your policy up to date in ExpenseIn is simple.  

You can quickly adjust the settings to reflect the latest rates, like those published quarterly by HMRC, and the change is automatically applied to all future claims.

That means no chasing employees, no manual reminders, and no risk of outdated calculations slipping through.  

6. A practical compliance framework  

While no software can guarantee compliance on its own, tools like ExpenseIn provide a strong foundation, helping finance teams build processes that align with HMRC guidance by default.   

The result is fewer errors, better recordkeeping, and more time to focus on higher-value tasks. 

Key takeaways for 2025 HMRC tax changes  

  • Mileage and allowances largely unchanged: The standard 45p/25p mileage rates remain frozen (unchanged since 2011). No new relief there, so plan budgets accordingly. Company car/van benefit charges edged up slightly for 2025–26, so update those P11D calculations.  

  • Digital records are a must: HMRC continues its Making Tax Digital drive, meaning all expense transactions should be recorded electronically. Digital receipts are fully accepted as long as they’re complete and legible. Ditch paper where possible and use a secure digital system for storing receipts for at least 6 years.  

  • VAT can be reclaimed on business expenses if you have valid VAT invoices. No receipt = no VAT reclaim, generally. Avoid flat per diem payments if you want to recover VAT – it’s better to reimburse actual costs with receipts so your company can claim the VAT back.  

  • Automation simplifies compliance: Using an expense management tool like ExpenseIn helps enforce these rules automatically (correct mileage rates, required receipt attachments, VAT tracking) and keeps you ready for any HMRC inspection. It’s a smart way to stay on top of 2025’s changes without adding workload. Book a demo to see it in action
