Top 10 Allowable Expenses for the Self-Employed

Maximise your take-home pay by claiming these common business expenses.

When you're self-employed, every penny counts. One of the most effective ways to reduce your tax bill is by claiming allowable business expenses. These are costs incurred "wholly and exclusively" for the purposes of your trade. Here are the top 10 allowable expenses you shouldn't miss.

1. Office Costs

Whether you rent a dedicated office space or work from home, you can claim for office-related expenses. This includes stationery, printing costs, postage, and computer software. If you work from home, you can claim a proportion of your household bills (like heating, electricity, and internet) based on the amount of time and space used for business.

2. Travel Expenses

You can claim for business travel, including train tickets, flights, and taxi fares. If you use your own vehicle, you can either claim a flat rate for mileage (currently 45p per mile for the first 10,000 miles and 25p thereafter) or claim the actual costs of running the vehicle, apportioned for business use.

3. Clothing Expenses

While you can't claim for everyday clothing (even if you wear it to work), you can claim for uniforms, protective clothing, or costumes for actors or entertainers.

4. Staff Costs

If you employ staff or use subcontractors, their wages, bonuses, pensions, and benefits are allowable expenses. You can also claim for employer's National Insurance contributions.

5. Things You Buy to Sell

The cost of your stock, raw materials, and the direct costs of producing your goods are all deductible.

6. Financial Costs

You can claim for business bank charges, interest on business loans, and alternative finance payments. You can also claim for accountancy and legal fees directly related to your business.

7. Costs of Your Business Premises

If you rent a business premises, you can claim the rent, utility bills, property insurance, and security costs.

8. Advertising and Marketing

The costs of promoting your business, including website hosting, advertising in directories, mailshots, and free samples, are fully allowable.

9. Training Courses

You can claim for training courses that help you improve the skills and knowledge you use in your business. However, you cannot claim for courses that help you start a new business or expand into a new area of business.

10. Subscriptions and Professional Fees

Membership fees for professional bodies or trade unions related to your work are allowable, as are subscriptions to trade or professional journals.

Keep Your Records!

The golden rule of claiming expenses is to keep meticulous records. Ensure you retain receipts, invoices, and bank statements for at least five years after the 31 January submission deadline of the relevant tax year. Using accounting software can make this process significantly easier.
