Allowable Expenses Review (Self-Employed)

If you are self-employed, claiming the right allowable expenses can make a real difference to your tax bill, but it is easy to miss deductions or claim items without the right support. An Allowable Expenses Review checks your current spending, record keeping, and expense categories so your Self Assessment is based on accurate, well evidenced figures.

More information

What the Allowable Expenses Review covers

The review is designed to help you claim what you are entitled to, while keeping your expenses HMRC-ready. Depending on how you currently track costs, it can include:

  • A check of your expense categories against HMRC rules for self-employed business costs
  • Identification of commonly missed expenses and timing issues (what to claim and when)
  • Guidance on mixed-use items (part business, part personal)
  • Checks for consistency between bank transactions, bookkeeping records, and your expense claims
  • Advice on what evidence to keep and how to store it
  • Clear notes on any areas that look high risk or need better support

Who this is most useful for

This service is a good fit if you are a sole trader or freelancer who:

  • Is preparing a Self Assessment return and wants confidence the expenses are right
  • Has grown quickly and your costs have become harder to track
  • Uses a home office, a personal vehicle, or a mobile phone for business
  • Has irregular income and wants to manage tax more predictably
  • Has kept records, but is not sure whether you are claiming everything you can

How the review works

You will share your current records, such as bookkeeping reports, bank exports, and receipts or invoices where available. Your expenses are then reviewed, grouped correctly, and sense-checked for allowability and evidence. You will get a practical summary of adjustments and recommendations, written in plain English.

What you get after the review

You will receive a clear list of suggested expense changes and any follow-up actions to strengthen your records. If needed, you will also get guidance on simple processes to keep your expenses tidy throughout the year, so your next tax return is easier and less stressful.

Frequently Asked Questions

What counts as an allowable expense for self-employed people?
An allowable expense is a cost that is wholly and exclusively for your business. Some costs are partly allowable if there is mixed personal use, but they need a fair method of apportionment. The review helps confirm what you can claim and what to avoid.
Do I need receipts for every expense?
HMRC expects you to keep evidence for what you claim, and receipts or invoices are the best support. Bank statements alone are not always enough, especially for unclear suppliers. The review will highlight where your evidence is strong and where to improve it.
Can you review expenses for previous tax years?
Yes, this can be done if you have the records and you want to check whether anything was missed. If changes are needed, the next step may be amending a past Self Assessment return. You will be told what is possible and what information is required.
How are home office and vehicle costs handled?
These costs often involve mixed use, so they need a sensible split between business and personal. The review can assess whether simplified expenses or actual cost apportionment is more suitable. You will get a clear approach you can apply consistently.
Will this service reduce my tax bill?
It can, if you have missed allowable deductions or claimed costs in a way that is not optimal. The main outcome is confidence that your expenses are complete, correctly categorised, and well evidenced. That reduces the risk of problems later and helps you plan your tax more accurately.
