The Freelance Business Setup Checklist (UK, 2026)

Setting up as a freelancer in the UK isn't complicated, but a surprising number of things need doing in the right order, and a few carry deadlines and penalties if you miss them. This checklist covers everything from choosing your business structure to sending your first invoice, split into stages you can work through over a couple of weeks.

If you're still deciding whether freelancing is right for you, read our getting started as a freelancer guide first. This checklist assumes you've made the decision and want to get set up properly.

Quick checklist: freelance business setup at a glance

1. Validate your offer and set your rates
2. Choose a structure: sole trader or limited company
3. Register with HMRC (or Companies House)
4. Open a separate business bank account
5. Set up bookkeeping and a tax savings pot
6. Get the right insurance
7. Sort your contracts, terms and invoicing
8. Check data protection and other legal obligations
9. Set up your workspace and tools
10. Build a portfolio and start finding clients

Each stage is broken down below.

Stage 1: Validate your offer and set your rates

Before you register anything, make sure there's paid demand for what you want to sell.

• Write down the one service you'll lead with, in a sentence a client would understand
• Look at who's hiring for it. Browsing the best freelance websites in the UK shows which skills clients are paying for right now, and our list of the best freelance jobs in the UK covers typical day rates
• Research what competitors charge and how they position themselves
• Set a day rate or project rate that covers tax, holidays, sick days and unbilled admin time. A common rule of thumb is to only bill around 60 to 70% of your working hours
• Decide your minimum project size and your payment terms (deposit, milestones, 14 or 30 days)

Stage 2: Choose your business structure

Most UK freelancers start as a sole trader or set up a limited company.

	Sole trader	Limited company
Setup	Register with HMRC, free	Incorporate at Companies House, £50 online
Admin	One Self Assessment return a year	Company accounts, confirmation statement, corporation tax return, payroll
Liability	You're personally liable for business debts	Liability limited to the company
Tax	Income tax plus Class 4 National Insurance on profits	Corporation tax on profits, then salary and dividends
Best for	Getting started, lower or uncertain income	Higher profits, contractors, clients who insist on it

• Pick a structure. If in doubt, start as a sole trader, it's simple to switch to a limited company later
• If you'll contract through a limited company, read up on IR35, as it decides whether you're taxed as an employee for a given contract
• Choose a business name. Sole traders can trade under their own name or a trading name, but can't use "Limited" or "Ltd". Check Companies House and trade mark records so you're not treading on anyone's toes
• Register a matching domain name and social handles

Stage 3: Register with HMRC

This is the step with a hard deadline.

• Sole traders: register for Self Assessment by 5 October after the end of the tax year you started trading in. The tax year runs 6 April to 5 April. See our note on the Self Assessment registration deadline for this year's dates
• Limited companies: incorporate at Companies House, then register for corporation tax within three months of starting to trade
• Note the trading allowance: if your total self-employed income is £1,000 or less in a tax year, you may not need to register at all
• Check the VAT threshold. You must register once your taxable turnover goes over £90,000 in any rolling 12 months. You can register voluntarily below that if it suits your clients
• Check whether Making Tax Digital for Income Tax applies to you. From April 2026 it covers sole traders and landlords with qualifying income over £50,000, dropping to £30,000 from April 2027 and £20,000 from April 2028. Our Making Tax Digital guide explains what changes

Stage 4: Separate your business money

• Open a business bank account. It's a legal requirement for a limited company and strongly recommended for sole traders, as it makes bookkeeping and tax returns far easier
• Open a savings account for tax and move a fixed percentage of every payment into it. 25 to 30% is a safe starting point for most sole traders
• Plan for payments on account. After your first Self Assessment bill, HMRC usually asks you to pay half of next year's bill in advance each January and July, which catches many new freelancers out
• Build an emergency buffer of at least three months' essential costs for quiet periods
• Start a personal pension. There's no employer contributing any more, and contributions get tax relief

Stage 5: Set up bookkeeping

• Choose accounting software. If you'll fall under Making Tax Digital, it needs to be HMRC-compatible. Compare options in our accountancy software roundup
• Decide how you'll record expenses and keep receipts (a photo app linked to your software is easiest)
• Learn which expenses are allowable, such as equipment, software, a share of home running costs, professional fees and business travel
• Keep records for at least five years after the 31 January submission deadline for the relevant tax year
• Decide whether you need an accountant. Many freelancers handle the first year themselves, then hand over once things get more complex

Our guide to managing your freelance finances and taxes covers Self Assessment, National Insurance and expenses in detail.

Stage 6: Get the right insurance

None of these are legally required for a one-person business, but a single claim can wipe out a year's profit.

• Professional indemnity: covers you if a client claims your advice or work caused them a loss. Many clients ask for it in their contracts
• Public liability: covers injury or damage to third parties, important if you visit client premises or meet clients
• Equipment and contents cover: check whether your home insurance covers business equipment, as many policies don't
• Employers' liability: a legal requirement as soon as you employ anyone
• Income protection: worth considering, as there's no sick pay when you're self-employed

Stage 7: Contracts, terms and invoicing

This is the legal checklist most new freelancers skip, and it's the one that saves the most money.

• Create a contract template covering scope, deliverables, deadlines, number of revisions, payment terms, ownership of work and cancellation
• Put your terms in writing for every job, even small ones. An email confirming scope and price is better than nothing
• Take a deposit before you start, typically 25 to 50% for new clients
• Set up an invoice template with your name or company name, address, invoice number, date, payment terms and bank details (limited companies must also show their registered number and office)
• Know your rights on late payment. Under the Late Payment of Commercial Debts Act you can charge statutory interest of 8% above the Bank of England base rate on overdue invoices to other businesses
• Have a plan for clients who won't pay. Our guide on what to do when a UK client doesn't pay covers the letter before claim and Money Claim Online

Stage 8: Data protection and other obligations

• Check whether you need to pay the ICO data protection fee. Most freelancers who hold client or customer personal data on a computer do, and it's a small annual fee
• Add a privacy notice to your website if you collect any personal data through it
• Check whether your trade needs a licence, certification or professional body membership
• If you work from a rented home, check your tenancy or mortgage doesn't restrict running a business from it

Stage 9: Workspace and tools

• Set up a dedicated workspace with a proper chair, desk and screen. Our guide to crafting the perfect home office for freelancers covers what's worth spending on
• Make sure your internet connection is reliable, with a backup such as mobile tethering
• Back up your work automatically to the cloud
• Pick a task manager and calendar. See our roundups of task management tools and digital calendars for freelancers
• Set working hours and stick to them. Our guide to time management as a freelancer helps with the discipline side

Stage 10: Portfolio and first clients

• Build a simple website or portfolio with three to five strong examples of your work. Our guide on how to build a freelance portfolio walks through it
• Update your LinkedIn profile to say you're freelancing and what you offer
• Tell your existing network. Former employers and colleagues are often a new freelancer's first clients
• Create profiles on one or two freelance platforms. Our PeoplePerHour vs Fiverr comparison helps you choose
• Set a weekly routine for outreach, even when you're busy. See finding freelance clients for tactics that work
• Plan to add more income streams over time so one lost client doesn't sink you. Our guide to diversifying income streams has ideas

After you launch: ongoing checklist

• Move your tax percentage into savings every time you're paid
• Update your bookkeeping weekly or monthly, not at the end of the year
• File your Self Assessment return and pay by 31 January
• Review your rates every six to twelve months
• Book time off, and look after yourself. Our guide to freelancer mental health covers stress, burnout and isolation

Frequently asked questions

What do I legally need to start freelancing in the UK?

As a sole trader, the legal minimum is registering with HMRC for Self Assessment by 5 October after the tax year you started, keeping records, and filing a return each year. You may also need to pay the ICO data protection fee, register for VAT if you pass £90,000 turnover, and hold employers' liability insurance if you take on staff.

Do I need a business bank account as a sole trader?

No, it isn't a legal requirement for sole traders, but it's strongly recommended. Mixing personal and business transactions makes bookkeeping harder and any HMRC enquiry more painful. Limited companies must have one.

How much should I save for tax as a freelancer?

Setting aside 25 to 30% of every payment is a safe starting point for most sole traders. Remember that your first bill may include a payment on account for the following year, so it can be larger than you expect.

Should I be a sole trader or a limited company?

Most freelancers start as sole traders because it's free, quick and has the least admin. A limited company can be more tax-efficient at higher profits and some clients require one, but it comes with more paperwork and accountancy costs. It's easy to switch later.

How long does it take to set up as a freelancer?

Registering with HMRC takes minutes online, though your Unique Taxpayer Reference arrives by post and can take a couple of weeks. Working through this whole checklist, including bank account, insurance, contracts and a basic portfolio, typically takes one to two weeks.
