This resulted in a late payment charge from HMRC, costing her an additional £75. You can find detailed guidance on income tax and self-assessment on GOV.UK.
Who Is Paying Too Much Self-Employed Tax in the UK?
Furthermore, many self-employed individuals are overpaying due to a lack of awareness about allowable expenses and tax reliefs. As a result, they miss out on significant savings.
- Sole Traders: These individuals are directly responsible for their business profits, which are taxed as income. Understanding your personal allowance and tax bands is vital to avoid overpayment.
- Freelancers: Whether you’re a writer, consultant, or designer, your income is subject to Income Tax and National Insurance. Incorrectly calculating these can lead to paying more than necessary.
- Gig Economy Workers: If you earn income from multiple platforms, consolidating your earnings and expenses accurately is key to correct tax calculation.
- New Self-Employed Individuals: Those just starting out may be unaware of the deadlines for tax registration and payments, leading to potential fines.
You can verify your tax obligations and understand your allowances on the HMRC website and GOV.UK.

- Calculate Your Taxable Profit: Subtract your allowable business expenses from your total income. This figure is your taxable profit. Ensure you’re claiming everything you’re entitled to, such as office supplies or travel costs.

Real Reader Experiences
“I used to dread tax season. As a freelance photographer in Edinburgh, my income was quite variable. I’d always just guess at my expenses and pay what I thought was right. For the 2023-2024 tax year, I ended up owing HMRC an extra £1,200 I hadn’t budgeted for. It was a shock! I found a local accountant who showed me all the things I could claim – software subscriptions, travel, even a portion of my home internet. Now, I’m properly organised, and last year, I actually received a refund of £350. It’s like getting an extra month’s worth of groceries for free!”
— Fiona M., Edinburgh, 2026
Case Study: How a UK Plumber Reduced His Tax Bill by £450
Mark, a sole trader plumber based in Birmingham, was consistently overestimating his tax payments, leaving him short of cash for business investments. He was paying an estimated £3,000 annually without a clear breakdown of his liabilities.
The starting situation: Mark had been self-employed for five years. He kept basic records in a notebook and paid a flat £250 per month towards his tax bill, unsure if it was too much or too little. This meant he was effectively overpaying by around £37.50 per month.
What he did:
- He downloaded the HMRC Self Assessment app to begin digitising his records.
- He reviewed his bank statements and receipts from the past two years, identifying £1,500 in previously unrecorded business expenses, including fuel, tools, and professional development courses.

Lesser-Known Rules That Could Save UK Self-Employed Hundreds
Furthermore, beyond the standard expense claims, several less obvious rules could boost your savings. These are often overlooked by busy sole traders.
Tip 1: The Trading Allowance
If your trading income is below £1,000 per tax year, you can claim the trading allowance and don’t need to declare it to HMRC or pay tax on it. This is a simple, automatic tax break. This could save you £200 if your income is between £500 and £1,000.
Tip 2: Claiming Home Office Expenses
You can claim a proportion of household bills (like energy, internet, and council tax) if you work from home. HMRC offers a simplified flat rate based on hours worked, or you can calculate the actual proportion based on your home’s size and usage. This could save £300 annually.
Tip 3: Business Travel Expenses
Don’t forget to claim for travel costs related to your business. This includes mileage for using your car for work, public transport fares, and even overnight accommodation if required. Keep accurate mileage logs. This can save you £100s per year.
Tip 4: Capital Allowances on Assets
When you buy assets for your business, like computers, machinery, or vehicles, you can claim capital allowances. The Annual Investment Allowance (AIA) allows you to deduct the full cost of qualifying assets from your profits in the year of purchase, up to a certain limit. This can significantly reduce your tax bill in the year of purchase.
Key Takeaway: Claiming home office expenses using the flat rate can save you £6 per week on average if you work 10 hours at home.
