Employee Expenses: What You Can Reimburse

Employee expenses can feel like a bit of a grey area. One person buys materials for a job. Another grabs a book of stamps. Someone else pays for travel and a professional subscription. They all feel like business costs but from a tax and VAT point of view, how you deal with them actually matters.

Get it right, and everything is clean and compliant. Get it wrong, and you can accidentally create tax issues, miss VAT claims, or even trigger a benefit in kind.

What do we mean by employee expenses?

Employee expenses are costs an employee pays personally and is reimbursed for by the business.

The key point is:

• The employee pays first

• The business reimburses them

Not all reimbursements are treated the same though, it depends on what the cost is and why it was incurred.

The golden rule

For a reimbursement to be tax-free the expense must be wholly, exclusively and necessary for business purposes. If that’s the case:

• No tax for the employee ✔

• No National Insurance ✔

• No benefit in kind ✔

If not… things can get more complicated.

1. Buying goods or services for the business

This is one of the most common scenarios.

Examples

• A construction worker buying materials for a job

• An employee picking up office supplies

• Someone buying packaging or tools

✔ How it should be treated?

If the purchase is genuinely for the business:

• The business reimburses the employee

• It’s treated as a normal business expense

• No tax implications for the employee

• The business can reclaim VAT if there is a valid VAT receipt

⚠ Watch out for

• Missing receipts

• Personal items mixed in

• Claims that are vague or unclear

Example

An employee buys £100 of materials (including VAT) for a job.

👉 Business reimburses £100

👉 VAT can be reclaimed (if properly documented)

👉 No tax for the employee

2. Small ad hoc expenses (postage, bits and pieces)

These are the everyday, low-value costs.

Examples

• Stamps

• Parking

• Small office items

• Printing

If it’s for business → reimburse tax-free. VAT may not be recoverable (e.g. stamps don’t include VAT) but where VAT exists and a receipt is available, it can usually be reclaimed

⚠ Watch out for

• Lack of receipts

• Rounding up or estimating costs

• Regular small claims that aren’t tracked properly

  
  

3. Travel and subsistence

✔ Allowable

• Business travel

• Mileage

• Public transport

• Meals when travelling for work

• Overnight stays

❌ Not allowable

• Normal commuting

• Everyday meals

• Personal travel

Example

Employee travels to a client: Train ticket ✔ Lunch while travelling ✔

Employee working at usual office: Lunch ❌

VAT can usually be reclaimed on travel and subsistence where applicable but not all items include VAT (e.g. train tickets often don’t)

4. Professional subscriptions

This is another common one.

✔ Allowable

• Subscriptions relevant to the employee’s role

• Memberships on HMRC’s approved list

Examples

• Professional bodies

• Industry memberships

• Certain training-related subscriptions

❌ Not allowable

• Personal interest subscriptions

• Unrelated memberships

5. Reimbursed vs allowances (important distinction)

There’s a big difference between reimbursing actual costs and paying a flat allowance

✔ Reimbursing actual costs

• Based on receipts

• Usually tax-free

❌ Flat allowances

• Paid regardless of actual spend

• Often treated as taxable income

• May need to go through payroll

Example

• Employee spends £20 → reimbursed £20 ✔ (fine)

• Employee receives £50 “just in case” ❌ (likely taxable)

  
  

6. When does it become a Benefit in Kind (BIK)?

This is where things can shift. A benefit in kind arises when the employee receives something of personal benefit that isn’t purely business-related

Examples

• Paying for personal items

• Covering non-business costs

• Providing something with a personal element

What happens then?

• The value becomes taxable

• It may need reporting on a P11D

• Employer may have NIC implications

Example

Employee buys:

• Work materials ✔

• And some personal items ❌

If reimbursed in full the personal element may be a benefit in kind

Common mistakes to avoid

❌ Reimbursing without receipts

Makes VAT recovery difficult and weakens your records.

❌ Claiming VAT incorrectly

No VAT receipt = no VAT claim.

❌ Treating everything as business

Just because it went through the business doesn’t make it business-related.

❌ Using allowances instead of reimbursements

Can unintentionally create taxable income.

❌ Not separating personal elements

Mixed purchases need to be split properly.

A simple way to think about it is ask yourself "Would the business have paid for this directly?"

If yes:✔ it's likely fine but if not it's worth checking

Final thoughts

Employee expenses don’t have to be complicated. Most of the time, it comes down to:

• Is it genuinely for business?

• Is it supported by a receipt?

• Is it being reimbursed accurately?

If yes then you’re usually on safe ground. If not that’s where tax and VAT issues can creep in. Handled properly, employee expenses are straightforward. Handled loosely… they can quietly become messyand as with most things in business a little structure upfront saves a lot of tidying up later.
