Self-Employed Allowable Expenses
As a self-employed individual, paying the right amount of tax is your responsibility. But did you know you can lower your tax bill by claiming your allowable business expenses? You can deduct these costs from your business profits, reducing the income you’re taxed on.
You can claim many things, including office supplies, travel expenses, etc. By understanding these deductions, you can keep more of your hard-earned money in your pocket and avoid overpaying your taxes.

Claiming allowable business expenses can save self-employed individuals a significant amount of money. These deductions reduce taxable income, ultimately allowing them to retain more earnings.
What Qualifies as Expenses for Self-Employed
Generally, an expense must be necessary and directly related to your business purposes to be deductible. Personal expenses, such as mortgage payments or grocery bills, cannot be deducted. However, many allowable business-related expenses, including office supplies, travel costs, and marketing expenses, can be deducted.
So long as an expense is for business purposes only and directly related to generating income, it will likely be deductible. As a result, keeping track of your business-related expenses throughout the year is vital to maximising your deductions come tax time.
How can I reduce my Self Assessment Tax bill by Claiming Expenses?
You must complete a self-assessment tax return yearly if the turnover is over £1000. Complete the tax return to calculate how much income tax and national insurance you owe.
As a Sole trader or freelancer, you must pay tax on everything over the personal allowance. By reducing the profits, the tax bill will be lower. It is essential only to claim what is allowable.
Below is an example of how it works using the personal allowance for 2023-2024 or 2024-2025, which is £12,570.
Sales throughout the tax year are £30,000, and you can claim business expenses of £8,500, with a tax allowance of £12,570.
The taxable profit is £30,000 – £8,500 = £21,500.
You would, therefore, pay 20% tax on £21,500 less tax allowance. £21,500 – £12,570 = £8,930.
If your profits are more than £12,570 a year, you must pay Class 4 National Insurance contributions. 6% on profits of £12,570 up to £50,270 – 2% on profits over £50,270.
