Many of our Customers have started their early careers with AccFirm

We’ve been working with this accounting team for over two years, and the difference has been incredible. From bookkeeping and VAT returns to corporation tax planning, everything is handled efficiently and on time. They keep us fully compliant with HMRC while helping us improve cash flow and profitability. I highly recommend their services to any business owner.
Sarah Thompson
Thompson Retail Ltd

As a contractor under the Construction Industry Scheme (CIS), I needed accountants who truly understand HMRC requirements. They managed my CIS registration, monthly returns, and self-assessment without any stress. Their guidance saved me both time and money. Professional, reliable, and always available when needed
James Patel
Self-Employed Contractor (CIS)

AccFirm took over our accounts when our previous firm kept missing deadlines. Within three months they had identified over £4,200 in tax savings we had been leaving on the table including expenses we had never been told we could claim. They handle everything from our quarterly VAT returns to our year-end accounts and payroll, and our dedicated accountant is always reachable. For any London small business owner, I cannot recommend them enough.

FAQs about Accountants for Self Employed in London
Do I need an accountant if I am self-employed?
You are not generally required to appoint an accountant, but professional support can make managing Self Assessment, bookkeeping, allowable expenses and tax obligations easier. An accountant for self employed individuals can also provide tax planning and business advice as your income grows.
What does a self-employed accountant do?
A self employed accountant can help with bookkeeping, Self Assessment tax returns, allowable expenses, VAT, tax planning and HMRC compliance. The level of support can be tailored to your business.
How much does an accountant for self-employed tax returns cost?
The cost depends on the complexity of your finances and the services you require. A straightforward Self Assessment return will normally require less work than an individual with VAT, multiple income sources, extensive expenses or complex tax affairs.
Can you prepare my Self Assessment tax return?
Yes. We can prepare and submit your Self Assessment tax return using the financial information and supporting records you provide. We can also review relevant business expenses and tax planning opportunities.
Can a self-employed accountant help reduce my tax?
An accountant cannot remove tax that is legally due, but they can help you claim legitimate allowable expenses and use relevant tax rules correctly. Forward tax planning can also help you make informed decisions about income, expenses, pensions and business structure.
What expenses can I claim as self-employed?
The expense must generally be incurred wholly and exclusively for the purposes of your business, subject to the specific HMRC rules. Depending on your circumstances, relevant costs may include professional subscriptions, insurance, business equipment, certain travel costs and other business expenses.
Can you help me register as self-employed?
Yes. We can explain the registration requirements and help you understand your responsibilities as a sole trader, including record keeping, Self Assessment and tax payments.
Do self-employed people need to register for VAT?
Not necessarily. VAT registration depends on factors such as taxable turnover and the applicable registration rules. We can review your turnover and business activities and explain whether VAT registration is required or whether voluntary registration may be appropriate.
Can you help freelancers and contractors with IR35?
Yes. Contractors may need to consider IR35 depending on their working arrangements and structure. We can provide accounting and tax guidance and help you understand when specialist employment-status advice may be required.
Should I stay self-employed or form a limited company?
There is no single answer for every business. The decision can depend on profit levels, commercial risk, administration, tax considerations, plans for growth and how you intend to take money from the business.
Can AccFirm help me if I have missed previous Self-Assessment tax returns?
Yes. AccFirm regularly works with self-employed individuals who have missed one or more Self-Assessment tax return deadlines. HMRC imposes automatic penalties for late filings starting at £100 for the first day late, rising to daily penalties after three months, and further penalties at six and twelve months. AccFirm can file all outstanding returns, calculate the tax and penalties due, and in many cases negotiate penalty reductions with HMRC on your behalf. The sooner you act, the lower your total liability will be. Contact us for a no-obligation review of your situation.
