Accounting for Staff Expenses in Ireland: How SMEs Lose Control and How to Fix It

Staff expenses seem straightforward until they're not. An employee submits a receipt three weeks late. Someone claims mileage for what turns out to be their daily commute. A round-sum allowance that was "always done this way" turns out to be taxable. And when Revenue asks for records, you're scrambling through email attachments and desk drawers.

For Irish SMEs, employee expenses sit at the intersection of tax compliance, payroll accuracy, and cash management. Get them wrong and you're exposed to Benefit-in-Kind (BIK) assessments, PAYE underpayments, and lost VAT reclaims. This guide covers what Revenue requires, which expenses are tax-free, the current rates, and how to build a system that actually works.

What Does Revenue Require for Employee Expense Compliance?

Revenue's expectations are clear, even if many businesses don't meet them. Every employee expense claim must have:

• Business purpose: Why was the expense incurred? "Lunch" is not enough. "Client meeting lunch with [name] at [venue]" is.
• Date and location: When and where did the expense happen?
• Itemised receipt: A credit card statement is not a receipt. Revenue wants the itemised receipt showing what was purchased.
• Correct categorisation: Travel, subsistence, accommodation, entertainment: each has different tax treatment.
• Approval: An authorised person should approve the claim before reimbursement.

Records must be retained for six years. The employer is responsible for maintaining the records and ensuring the expense system is compliant, even though the employee submits the claim.

What Revenue inspectors commonly focus on: round-sum allowances paid without matching documentation, mileage claims without travel logs, subsistence paid for trips to the employee's normal place of work, and expenses with a personal element that haven't been apportioned.

Which Staff Expenses Are Tax-Free, Taxable, or Treated as BIK?

This is where SMEs make the most mistakes. The distinction matters because it determines whether the expense goes through payroll as a taxable benefit or is reimbursed tax-free.

Tax-free (if properly vouched): Legitimate business expenses reimbursed to the employee on foot of receipts and within Revenue's approved rates. These include travel to a temporary place of work, subsistence at approved rates, and business-related purchases made on behalf of the company.

Taxable / BIK: Benefits from employment that are not reimbursements of actual business costs. A round-sum monthly "expense allowance" that isn't tied to actual receipts is taxable. A company car used for personal travel is a BIK. Accommodation upgrades, personal meals, and spouse travel costs are all taxable.

The critical distinction to get right:

• Travel vs commuting: Travel from your home to your normal place of work is commuting. It is not a deductible business expense. Travel from your normal place of work to a client site, or to a temporary work location, qualifies. Getting this wrong is one of the most common audit findings.
• Flat-rate allowances: If you pay a fixed monthly amount regardless of actual expenses incurred, Revenue is likely to treat it as taxable pay unless you can demonstrate it matches actual costs and is within approved rates.

What Are the Current Mileage, Subsistence, and Remote Working Rates?

Civil Service Mileage Rates

Revenue accepts the civil service mileage rates as the benchmark for tax-free reimbursement. As of 2026, the rates for motor cars are:

Distance Band	Rate per km (engine up to 1200cc)	Rate per km (1201-1500cc)	Rate per km (1501cc+)
0-1,500 km	€0.4180	€0.4340	€0.5182
1,501-5,500 km	€0.7264	€0.7918	€0.9063
5,501-25,000 km	€0.3178	€0.3179	€0.3922
25,001+ km	€0.2056	€0.2385	€0.2587

These rates cover fuel, insurance, depreciation, and maintenance. If you pay above these rates, the excess is taxable. Always verify against the latest Revenue civil service rates as they can change.

Employees must maintain a mileage log: date, destination, purpose, and kilometres. Without a log, the mileage claim is not properly vouched and may not qualify for tax-free treatment.

Subsistence Rates

Subsistence covers meals and incidental costs when an employee is away from their normal place of work on business. The tax-free rates depend on the duration of the trip:

• Day allowance (5-10 hours): €19.25
• Day allowance (10+ hours): €46.17
• Overnight Normal Rate (domestic): €205.53 (covers accommodation and meals)

These are maximum tax-free amounts. Actual costs above these rates need receipts and justification, and may be partially taxable. Subsistence is not payable for travel to the employee's normal place of work.

Remote Working Allowance

Employers can pay employees who work from home an allowance of €3.20 per day without it being treated as a taxable benefit. This covers additional household costs like electricity, heating, and broadband. The payment must be for days actually worked from home.

Employees who don't receive the allowance from their employer can claim a tax deduction of 30% of certain utility costs (electricity, heating, broadband) proportioned to their work-from-home days.

Small Benefits Exemption

The small benefits exemption allows employers to give employees up to two non-cash benefits per year (e.g., gift vouchers) with a combined value of up to €1,500 without triggering BIK. The benefit must be non-cash: a voucher or gift card qualifies; a cash bonus does not.

What Are the Most Common Expense Mistakes Irish SMEs Make?

• Paying mileage for commuting: Travel from home to the office is not a business expense. Paying mileage for it creates a taxable benefit and a payroll issue.
• Round-sum allowances without receipts: A €200 monthly "expense allowance" not tied to actual costs is taxable income. It must go through payroll with PAYE, PRSI, and USC deducted.
• Missing or inadequate receipts: A credit card statement showing "Restaurant €87.50" is not an itemised receipt. Revenue expects to see what was purchased.
• Not distinguishing business entertainment from subsistence: Client entertainment has different rules (typically not tax-deductible for the company). Staff meals while travelling are subsistence. Conflating them creates problems.
• Delayed submissions: Employees who submit expenses months late create reconciliation issues, cash flow surprises, and missing VAT reclaim windows.
• No written policy: Without a clear expense policy, claims are inconsistent and disputes are inevitable. Revenue also expects to see a policy during audits.

How Do You Build an Expense System That Actually Works?

The goal is simple: every expense is captured, categorised, approved, and reimbursed quickly, with a full audit trail. Here's how:

1. Write a clear expense policy. One page is enough. Cover what's claimable, what's not, the receipt requirement, mileage log requirements, approval process, and submission deadlines (e.g., within 7 days of the expense).
2. Use expense software or a structured process. Xero Expenses, Dext, Expensify, or even a simple shared form with receipt uploads. Anything is better than emailed photos and scraps of paper.
3. Require receipts at the point of expense. The longer someone waits, the more likely the receipt is lost. Mobile apps that let employees photograph receipts immediately are the simplest solution.
4. Set approval workflows. Every claim should be reviewed and approved before reimbursement. This catches errors, personal expenses, and policy violations before they hit the books.
5. Process reimbursements on a regular cycle. Weekly or bi-weekly. Fast reimbursement encourages timely submission. Slow reimbursement encourages procrastination and batch submissions that are harder to verify.
6. Reconcile expenses monthly. Match claims to bank statements, check VAT treatment, and ensure everything is correctly coded in your accounting software.

Frequently Asked Questions About Staff Expenses in Ireland

Can I claim travel expenses for my daily commute?

No. Travel between your home and your normal place of work is commuting, not a business expense. It cannot be reimbursed tax-free. Travel from your workplace to a client site, or to a temporary work location, does qualify.

Are meal expenses tax-free?

Subsistence payments within Revenue's approved rates are tax-free when the employee is travelling away from their normal place of work on business. Meals at or near the normal workplace are not subsistence and cannot be reimbursed tax-free.

What happens if we pay above the approved mileage rates?

The portion above the civil service rate is treated as taxable income. It must go through payroll with PAYE, PRSI, and USC applied. Many businesses don't realise this and face underpayment assessments during Revenue audits.

Do we need to keep physical receipts or are digital copies acceptable?

Revenue accepts digital copies (scans, photographs) provided they are legible and retained for six years. Most modern expense tools capture and store digital receipts automatically, which is both easier and more reliable than paper filing.
