Let Sleek sort your Freelance tax the smart way
Freelance tax in the UK can be confusing, but getting it right is essential if you want to stay compliant and keep more of what you earn. Whether you’re a full-time freelancer or juggling a side hustle, understanding what tax you owe, and how to pay it, can save you a lot of money and stress.
In this guide, we’ll break down how freelance tax works, what you can claim, and how to calculate your take-home pay. Plus, we’ll share practical tips on where to find accounting services tailored to freelancers, if you’d rather avoid doing it all yourself.
What taxes do freelancers pay?
Freelancers are typically classed as self-employed. That means you’re responsible for registering with HMRC, reporting your income, and paying the right tax. Here’s what that involves:
- Income Tax on your profits
- National Insurance Contributions (NICs)
- VAT, if your turnover exceeds £90,000
- Possibly Corporation Tax, if you set up a limited company
Let’s break these down.
Need help with Freelance Tax in the UK?
1. Income Tax for freelancers
What’s required:
Everyone gets a Personal Allowance, currently £12,570, before Income Tax kicks in. What you pay after that depends on how much you earn:
| Band | Taxable income range | Tax rate |
| Personal Allowance | Up to £12,570 | 0% |
| Basic rate | £12,571 – £50,270 | 20% |
| Higher rate | £50,271 – £125,140 | 40% |
| Additional rate | Over £125,140 | 45% |
Scottish taxpayers use slightly different bands, but the Personal Allowance still applies.
2. National Insurance Contributions (NICs)
If you’re self-employed, you’ll usually pay two types of NICs:
| NIC Type | When you pay it | 2024/25 Rate |
| Class 2 | No longer required if profits > £12,570 | N/A (voluntary if low) |
| Class 4 | On profits between £12,570 – £50,270 | 8% |
| On profits over £50,270 | 2% |
Voluntary Class 2 NICs are still an option if your profits are under £6,725, which is useful for maintaining your entitlement to certain state benefits.
If you’re still unsure about what you’ll owe in NICs, read our breakdown on how much National Insurance freelancers pay in the UK.
3. VAT for freelancers
If your annual turnover exceeds £90,000, you must register for VAT. This means:
- Charging VAT on client invoices
- Submitting VAT returns (usually quarterly)
- Paying VAT to HMRC
Standard VAT is 20%, with reduced (5%) or zero (0%) rates for specific goods or services.
What expenses can freelancers claim?
Claiming legitimate business expenses lowers your taxable income and your tax bill. Instead of listing them all in bullets, let’s break them down by type:
1. Office and admin
If you work from home, you may be able to claim a proportion of your:
- Rent or mortgage interest
- Council tax
- Utilities
- Internet and phone bills
You can also claim for office supplies like stationery, printer ink, and postage; provided they’re for business use.

2. Equipment and software
Laptops, monitors, phones (if used for work), cameras, and software subscriptions can all be claimed as allowable expenses. Just remember, if something is used for both personal and business purposes, you can only claim the business portion.
3. Travel and marketing
Costs for public transport, mileage to client meetings, business insurance, ads, website hosting, and even networking event tickets may be claimable. Keep receipts and log your journeys to back up any travel claims.
How to calculate your take-home pay
Here’s how to work out what you’ll actually earn after tax:- Add up your freelance income for the year
- Subtract all allowable business expenses to find your profit
- Apply Income Tax and NICs based on your profit
- The amount left is your take-home pay
How to pay tax as a freelancer
It’s your responsibility to:- Register for Self-Assessment once you earn over £1,000/year
- File your tax return online by 31 January each year
- Pay any tax due by 31 January (and again by 31 July if required)
Missing a tax deadline can cost you £££s in penalties. HMRC doesn't take "I forgot" as an excuse, so staying ahead is simpler (and cheaper!)
Managing freelance tax payments: practical tips
Rather than scrambling in January, make life easier by planning ahead. Here’s how:
Start by estimating your tax bill; roughly 25–30% of your income is a safe ballpark. Set up a dedicated tax savings account and move money into it each time you get paid. Track your income and expenses consistently using software or a spreadsheet.
And review your setup regularly. If your income grows or you change services, your tax position may shift too.
Freelancing alongside a job? Here’s what to know
You can be both employed and self-employed, but just make sure to report all income in your Self-Assessment return. HMRC will factor in tax you’ve already paid via PAYE and adjust your bill accordingly.
You’ll still pay NICs through your job (Class 1) and through your freelance work (Class 4), based on profits.
Payslips for freelancers: worth doing?
You won’t get a traditional payslip, but it’s smart to generate one yourself. Especially if you’re applying for a mortgage, loan, or rental. It shows consistent income and helps you keep tabs on your finances.
Your DIY payslip should include:
- Your name and address
- Payment period and date
- Gross earnings
- Tax and NIC deductions
- Net pay
Use accounting software or a payslip generator for a professional-looking record.
Want to reduce your freelance tax bill?
A few legal strategies can help lower your tax liability:
- Claim all allowable expenses
- Make pension contributions (to reduce taxable income)
- Donate using Gift Aid
- Consider whether switching to a limited company could save tax
Effective tax planning doesn’t need to be complex—it just needs to be proactive.
IR35 and off-payroll working rules
If you’re freelancing through a limited company, check if IR35 rules apply. These determine whether HMRC sees you as genuinely self-employed or effectively an employee in disguise.
Being “inside IR35” means paying tax like an employee. It can get complex, so if you’re unsure, speak to an expert or use HMRC’s CEST tool.
