UK employers can reimburse travel and subsistence tax-free using HMRC's benchmark scale rates: £5 for 5-hour absences, £10 for 10-hour absences, £25 for overnight stays (plus up to £5 for evening meals). Mileage is reimbursed at 45p/25p per mile under AMAP. Per diems above these rates require bespoke rate applications to HMRC. TravelPerk, Payhawk, and Webexpenses are the leading platforms for managing business travel expense compliance in the UK.

Travel and subsistence is the expense category most likely to trigger an HMRC compliance enquiry. The rules are more nuanced than the simple pence-per-mile framework covering local business mileage: per diems, subsistence benchmarks, overseas allowances, temporary workplace rules, and the distinction between deductible travel and non-deductible commuting all generate consistent errors in employer expense policies. At the same time, travel represents some of the largest per-employee expense spend - a field sales team or professional services practice with regular overnight travel can easily generate £50,000-£100,000 in annual travel and subsistence claims. Getting the compliance framework right, and the software to enforce it, pays dividends in both HMRC risk management and finance team efficiency.
HMRC Subsistence Rates: The Benchmark Framework
HMRC's benchmark scale rates for subsistence allow employers to reimburse employees for meals and incidental costs during business travel without requiring receipts for every individual item - provided the reimbursement does not exceed the benchmark rate and the employee is genuinely away from their normal place of work. This is a meaningful practical benefit: rather than requiring employees to produce a receipt for a £4.50 sandwich, the employer can pay the benchmark rate for a qualifying absence and treat it as non-taxable without individual receipt evidence.
The current HMRC benchmark scale rates are: £5 for an absence of five hours or more from the normal workplace (one meal rate), £10 for an absence of ten hours or more (two meal rate), and £25 for absences of fifteen hours or more that extend beyond 8pm (the extended meal rate, sometimes referred to informally as the overnight rate - though it does not cover accommodation). An additional £5 per night is available for incidental overnight expenses where the employee stays away from home. These rates are set by HMRC and updated periodically - employers should verify current rates on HMRC's Employment Income Manual before publishing their expense policy.
A critical qualifying condition: the benchmark rates apply only where the employee is away from their normal place of work and the journey qualifies as business travel (not ordinary commuting). For employees with a fixed permanent workplace, this is straightforward. For employees with no fixed workplace, or those working from home, the temporary workplace rules under section 339 of the Income Tax (Earnings and Pensions) Act 2003 determine whether a given journey qualifies. The ITEPA 2003 definition of a temporary workplace - one attended for a limited duration or purpose - is the reference test.
Employers wishing to pay above the benchmark rates without operating PAYE on the excess must apply to HMRC for a bespoke scale rate agreement. HMRC requires evidence of actual costs incurred by a representative sample of employees before approving a higher rate. This process is relevant for businesses with high-cost travel patterns - London-based teams with expensive meal costs, or businesses requiring overnight stays in cities where accommodation and subsistence costs exceed the benchmark rates significantly.
Mileage: AMAP Rates and Temporary Workplace Rules
Business travel mileage reimbursement under HMRC's Approved Mileage Allowance Payment framework is covered in full in the HMRC mileage rates guide. The key intersection with travel expense management is the temporary workplace rule: employees travelling from home to a temporary workplace - rather than their permanent employer premises - can claim mileage for the full home-to-site distance. This is a meaningful difference from ordinary commuting, where no mileage claim is permitted.
The temporary workplace rule has a 24-month limit: if an employee attends the same workplace for more than 24 months continuously, or is expected to do so for more than 40% of their working time, HMRC may reclassify it as a permanent workplace, eliminating the mileage deductibility. Expense management software that tracks journey destinations and flags engagements approaching the 24-month threshold provides a useful early warning for businesses with long-term project assignments or secondments.
Overseas Travel: Per Diems and Foreign Subsistence
HMRC publishes a separate set of subsistence scale rates for overseas travel, covering over 100 countries with country-specific day rates and overnight rates. These rates are updated periodically and allow employers to reimburse overseas business travel subsistence without individual receipts, provided the reimbursement does not exceed the published rate for the relevant country and city. The overseas scale rates are published in HMRC's Employment Income Manual and on gov.uk.
For businesses with significant overseas travel, the administrative complexity of applying the correct country-specific rate to each claim is a genuine operational challenge. Expense management platforms that integrate HMRC's overseas scale rates - automatically applying the correct country rate based on the destination logged in the claim - substantially reduce the error rate compared with manual rate lookup. Payhawk and TravelPerk both maintain updated overseas rate tables within their platforms.
VAT reclaim on overseas travel expenses is a separate consideration. UK businesses can reclaim VAT on UK-incurred expenses in the normal way. VAT incurred in EU member states on business travel can be reclaimed via the EU VAT refund procedure - a process that is now more administratively complex for UK businesses following the UK's departure from the EU VAT area. Some expense platforms include EU VAT reclaim tracking as a feature; others require manual identification of reclaimable EU VAT. The ICAEW and HMRC guidance on overseas VAT reclaim is the relevant reference for finance teams managing significant EU travel budgets.

Software for Travel Expense Management
TravelPerk occupies a distinct position in the travel expense market because it combines travel booking (flights, hotels, rail) with expense management in a single platform. This integration eliminates one of the most persistent friction points in travel expense management: the disconnect between the booking system (where travel is planned and purchased) and the expense system (where costs are recorded and approved). In a TravelPerk workflow, a booked trip automatically generates an expense record pre-populated with the booking cost, reducing employee data entry to confirming business purpose and adding any incidental expenses not captured at booking. Pricing is available on request; TravelPerk charges a per-booking fee model.
SAP Concur is the enterprise standard for travel and expense management, widely deployed in UK mid-market and large corporate businesses. Its travel booking module integrates with GDS (Global Distribution System) data, providing real-time fare comparisons against company travel policy. The expense module handles multi-currency claims, per diem policy enforcement, and integration with SAP's ERP suite. Implementation complexity and cost make it appropriate for businesses above 500 employees with dedicated travel management programmes; below this scale, the platform is typically over-specified.
Payhawk handles travel and subsistence claims well within its broader expense management platform. Its overseas subsistence rate tables, VAT extraction from foreign receipts, and multi-currency support make it a capable option for businesses with regular international travel. For UK-centric businesses, Payhawk's strength is the integration between corporate card transactions (automatically imported), receipt capture, and accounting system sync.
Webexpenses is a UK-headquartered platform with strong adoption among professional services firms and public sector organisations. Its mileage module includes HMRC AMAP rates and temporary workplace tracking. Subsistence rate enforcement - flagging claims above HMRC benchmark rates - is configurable. P11D-ready reporting for any taxable travel benefit is a standard feature. For a broader comparison of expense management platforms including small business options, see the best expense management software guide.

Common Compliance Failures in Travel Expense Management
HMRC compliance checks on travel and subsistence typically focus on four recurring failure patterns. Understanding these shapes both the expense policy and the software configuration required to prevent them.
The first failure pattern is subsistence claims without qualifying absence evidence. The benchmark rates require the employee to have been absent from their normal workplace for the qualifying period (five or ten hours). Without a record confirming the absence duration - a meeting confirmation, travel booking, or manager approval note - the claim cannot be confirmed as qualifying. Expense software that captures absence duration as a required field on subsistence claims prevents this gap.
The second failure pattern is mileage claims that include ordinary commuting. Employees who work from home and travel to a client site may legitimately claim the full home-to-client distance if the client site qualifies as a temporary workplace. But employees who travel from home to their employer's permanent office are commuting, not on business travel, regardless of whether they use their own car. Expense software cannot make this determination automatically - it requires clear policy guidance and manager approval.
The third failure is accommodation claims without VAT receipts. Hotel accommodation in the UK carries 20% VAT. A VAT-registered business can reclaim that VAT - but only with a valid VAT receipt showing the hotel's VAT registration number and a VAT breakdown. A bank statement or credit card receipt is not a valid VAT receipt for reclaim purposes. Mobile receipt capture at the point of checkout, before the paper receipt is lost, is the most effective prevention measure.
The fourth failure is overseas per diem claims above HMRC's published overseas scale rates without a bespoke rate agreement in place. Finance teams that set per diem policies based on cost-of-living estimates rather than HMRC's published rates may be reimbursing above the approved level, creating a taxable benefit in kind that should have been P11D-reported.
FAQ
Can I pay employees a flat daily per diem for all business travel without receipts?
Within HMRC's benchmark scale rates (up to £10 for a 10-hour absence, for example), yes - receipts are not required for individual meals where the claim does not exceed the benchmark rate and the absence qualifies. Above the benchmark rates, the excess is taxable unless you hold a bespoke scale rate agreement from HMRC, which requires an application supported by evidence of actual costs. A flat per diem above benchmark rates without an HMRC agreement creates a P11D reporting obligation on the excess.
Is accommodation a taxable benefit if the employer books and pays directly?
Where the employer arranges and pays for accommodation directly (through a corporate booking platform or company credit card), and the accommodation is genuinely required for business travel to a temporary workplace, it is not a taxable benefit. The tax exemption requires that the travel itself qualifies as business travel, that the employee is away from home overnight because of the business requirement, and that the accommodation cost is reasonable. Lavish or personal-use accommodation booked alongside legitimate business travel may require apportionment.
How do I reclaim VAT on employee hotel and meal expenses?
VAT on UK hotel accommodation (20%) and meals can be reclaimed where the supplier is VAT-registered and has provided a valid VAT receipt. The expense must have a business purpose and the employee must be acting as the employer's agent. For receipts under £250, a simplified VAT receipt (showing VAT-inclusive total and VAT number) is acceptable. Above £250, a full VAT invoice showing the net amount, VAT rate, and VAT amount is required. Fuel VAT on mileage claims is subject to HMRC's fuel advisory rate framework rather than actual fuel receipt VAT.
What is HMRC's view on business class travel for employees?
Business class travel is not inherently a taxable benefit - it is the cost of business travel, and the mode of transport is a matter for employer policy rather than HMRC prescription. However, where an employee upgrades at personal preference and the employer reimburses the upgrade cost, the upgrade element may be a benefit in kind if it exceeds what was necessary for the business purpose. Most expense policies specify a travel class by seniority level and journey duration, with upgrades above the policy level treated as personal expenditure.
Do the HMRC subsistence benchmark rates apply to self-employed individuals?
The benchmark scale rates are an employer/employee framework and do not apply directly to self-employed individuals. Self-employed people can deduct travel and subsistence costs that are wholly and exclusively for business purposes under the trading income rules, but cannot use the HMRC benchmark rates as a substitute for evidencing actual costs. HMRC's simplified expenses scheme for self-employed individuals includes fixed mileage rates (matching AMAP) but does not include subsistence benchmarks equivalent to the employment framework.
How We Verified
This article draws on HMRC's Employment Income Manual (sections EIM05200-EIM05300 on subsistence), HMRC's published benchmark scale rates and overseas scale rates on gov.uk, the Income Tax (Earnings and Pensions) Act 2003 at section 339 (temporary workplace definition), and publicly available pricing and feature documentation from platforms named. Subsistence rate figures reflect HMRC published rates as of May 2026 and should be verified against current HMRC guidance before application in expense policies.
