Accountants for Freelancers in London

Written by Sharaz Zaman, Founder of GM Professional Accountants, AAT Member with 15+ years London accounting experience.

If you are searching for an accountant for freelancers in London, GM Professional Accountants provides AAT regulated Self Assessment, bookkeeping and tax planning support for sole traders, contractors and limited company freelancers across London and Essex. We handle the paperwork, work out your allowable expenses and keep you compliant with HMRC deadlines, so you can focus on client work rather than spreadsheets. Whether you invoice through a sole trader setup or your own limited company, our team translates the tax rules into plain English and files your return correctly the first time.

In plain terms, an accountant for freelancers is a qualified professional, usually AAT, ACCA or ACA regulated, who manages Self Assessment tax returns, bookkeeping, allowable expense claims and HMRC compliance for self employed sole traders and limited company contractors working across multiple clients and projects.

Who Needs an Accountant for Freelancing in London?

London has one of the largest concentrations of self employed professionals in the UK, and industry estimates put the number of freelance and self employed workers active in and around the capital at well over 1.9 million. If you are a designer, developer, IT contractor, coach, consultant, photographer, tutor, personal trainer or content creator invoicing several clients without an employer deducting PAYE for you, you fall into this group. A general practice accountant who mostly handles limited companies or payroll clients may not know the specific expense rules, IR35 tests or MTD thresholds that apply to freelance income, which is why a freelancer focused accountant matters.

What Does an Accountant for Freelancers Actually Do?

A freelancer accountant prepares and files your Self Assessment tax return, maintains your bookkeeping records, identifies every allowable expense you can legitimately claim, and checks your IR35 status if you work through contracts or intermediaries. If you register for VAT once you pass the £90,000 turnover threshold, we manage your VAT returns too. As your freelance income grows and you start thinking about limited company structures, growth planning or cash flow forecasting, our business advisory service steps in alongside your day to day compliance work.

Which Freelance Sectors Do We Support?

Every freelance discipline throws up its own quirks when it comes to expenses and income timing, so we work across the full range of London’s freelance economy rather than offering one generic package. This includes creative freelancers such as graphic designers, copywriters, photographers and video editors, technology contractors including developers, UX designers and IT consultants, health and wellbeing professionals such as personal trainers, therapists and freelance nurses, and business freelancers including management consultants, marketing specialists and coaches. If you work through an intermediary or agency, we also review your IR35 status so you understand whether your engagement falls inside or outside the off payroll working rules, and what that means for your take home pay.

Should You Register as a Sole Trader or a Limited Company?

Most freelancers start as sole traders because setup is simple and there is less admin, but once profits climb past roughly £40,000 to £50,000 a limited company often becomes more tax efficient. The table below sets out the main differences.

If you make the move to a limited company, our annual accounts services handle your statutory filings with Companies House and HMRC. Many freelancers also earn income outside their trade, for example letting out a spare property, and if that applies to you our property investors and landlords service covers the Section 24 and MTD landlord rules that sit alongside your freelance return.

How Does Making Tax Digital Affect Freelancers From 2026?

Making Tax Digital for Income Tax, known as MTD ITSA, is already in force. Since 6 April 2026, freelancers and landlords with combined gross income over £50,000 must keep digital records and send quarterly updates to HMRC instead of one annual return, with the first quarterly submission due by 7 August 2026. From 6 April 2027 this widens to anyone with gross income over £30,000, and a further drop to £20,000 is expected from April 2028. Gross income means turnover before expenses, so it catches more freelancers than the threshold figure alone suggests. We help clients confirm whether they fall into the current or next phase and get compliant software in place ahead of the deadline.

What Expenses Can a Freelancer Claim?

Common allowable expenses for freelancers include a proportion of home office costs and utility bills, travel and mileage between client sites, equipment and software subscriptions, professional indemnity insurance, marketing and website costs, training directly related to your work, and our own accountancy fees. Missing these adds up quickly. HMRC applies a £100 immediate penalty for a late Self Assessment return, followed by £10 daily penalties for up to 90 days, so getting expenses and deadlines right the first time protects both your tax bill and your cash flow. We also flag anything that looks like a grey area, for example mixed personal and business use of a laptop or phone, so you claim confidently rather than guessing and risking an HMRC enquiry further down the line.

Why Choose GM Professional Accountants as Your Freelancer Accountant in London?

We are an AAT regulated practice with offices across Ilford, Wimbledon, Old Street and East London, and we serve clients across London and Essex both in person and remotely. Every freelancer client is assigned a named accountant rather than a rotating account manager, our fees are fixed and transparent from the outset, and we work with the sector terminology that actually applies to you, including IR35, MTD ITSA, CIS for freelance subcontractors and Section 24 for freelancers who also let property. Sharaz Zaman personally reviews every practice’s client onboarding to make sure nothing about your situation is generic.

We confirm we serve freelancer clients across London and Essex, whether you prefer to meet at our Ilford, Wimbledon or Old Street offices, drop in near our East London base, or handle everything remotely by phone and video call. Many of our freelancer clients split their time between client sites across the capital and simply need a responsive accountant who answers questions quickly rather than making them wait for a scheduled review meeting.

Frequently Asked Questions

How much does an accountant for freelancers in London cost?

Fees vary with the complexity of your affairs, but our freelancer packages start from as little as £30 a month for straightforward sole trader clients, with a fixed quote agreed before any work begins.

Do freelancers legally need an accountant?

No, you can file your own Self Assessment return directly with HMRC. Most freelancers use an accountant to save time, reduce the risk of penalties, and make sure they claim every allowable expense.

What is the Self Assessment deadline for freelancers?

Online returns and any tax owed are due by 31 January following the end of the tax year. You must register for Self Assessment by 5 October if you are filing for the first time.

Can a freelancer claim working from home expenses?

Yes, you can claim a proportion of household costs such as heating, electricity and internet based on the space and time used for work, or use HMRC’s simplified flat rate method.

Does Making Tax Digital apply to me as a freelancer?

If your combined gross self employment and property income is over £50,000 you are already required to comply from April 2026. That threshold drops to £30,000 from April 2027, so many more freelancers will be brought into MTD ITSA over the next two years.
