Set Aside Taxes from Each Payment
For self-employed individuals and those in the gig economy, one of the most important things to understand about income tax withholding is that it's entirely your responsibility. Unlike W-2 employees, you don't have an employer automatically setting aside taxes, so you need to plan ahead.
A practical approach is to allocate 25-35% of each payment you receive into a separate tax savings account. To make that money work a bit harder, consider placing it in a high-yield savings account so it can earn interest while it sits there. This can potentially offset any minor estimated tax penalties if you decide to pay everything at once instead of making quarterly estimated payments.
It's also worth considering how your business is structured. If your self-employed income is significant, forming an LLC and electing to be taxed as an S Corporation can potentially reduce self-employment taxes. This strategy allows you to pay yourself a reasonable salary while taking the remaining income as distributions, which aren't subject to Social Security and Medicare taxes.
Keep Detailed Records of Income and Expenses
One key piece of advice for anyone self-employed or in the gig economy is to set aside a portion of every payment you receive, ideally around 20-30%, to cover your income tax and National Insurance. Unlike employed roles where tax is deducted automatically, it's your responsibility to budget for your year-end bill.
It's also crucial to keep clear, up-to-date records of your income and business expenses. This not only helps reduce your taxable income through legitimate deductions (like travel, home office costs, or equipment), but also ensures you stay compliant and avoid penalties. Consider using dedicated accounting software to track everything, especially with Making Tax Digital requirements being phased in from April 2026 for those earning over £50,000.
Understand UK Self-Assessment Tax Responsibilities
For anyone self-employed or working in the gig economy in the UK, the most important thing to know is that tax isn't automatically deducted from your income. You're responsible for setting it aside and paying it yourself. It can be a shock if you're used to PAYE, where it's all done for you.
A good rule of thumb is to set aside around 20 to 30% of your income for tax and National Insurance, depending on your earnings. It's also wise to keep this in a separate savings account, so you're not tempted to dip into it.
Crucially, register for Self Assessment with HMRC early, and keep track of your income and expenses throughout the year. Waiting until January to figure it all out is where the panic sets in. Planning ahead gives you control and peace of mind.
For the 2024/25 tax year, you need to register for Self Assessment by 5th October 2025, with tax returns due by 31st January 2026. The tax-free Personal Allowance remains at £12,570, with basic rate tax at 20% for income between £12,571 and £50,270, higher rate at 40% for £50,271 to £125,140, and additional rate at 45% for income over £125,140. Remember that if your income exceeds £100,000, your Personal Allowance reduces by £1 for every £2 earned, until it's completely lost at £125,140.
In addition to Income Tax, you'll pay Class 2 National Insurance contributions (NICs) at £3.45 per week if your profits exceed £12,570 (2024/25), and Class 4 NICs at 9% on profits between £12,570 and £50,270, and 2% on profits above that threshold. If your annual turnover exceeds £90,000 (from 1 April 2024), you must also register for VAT and charge it on your services.
Keep comprehensive records of all business expenses, as these reduce your taxable profit. This includes costs like travel, home office expenses, equipment, software subscriptions, and professional development. Many self-employed people miss out by not claiming all eligible expenses.
Consider using accounting software compatible with Making Tax Digital (MTD), as this will become mandatory for all self-employed individuals with business income over £50,000 from April 2026 (and those with income over £30,000 from April 2027). Payment on Account is another important aspect to understand. If your tax bill exceeds £1,000, HMRC will usually require you to make advance payments towards your next year's bill, which can significantly impact your cash flow in your second year of self-employment.
