Sole Trader Accountants, London
Your self-assessment and tax, handled properly.
Most sole traders in London are filing their own self-assessment, guessing at allowable expenses, and finding out their tax bill far too late to do anything about it. A chartered accountant changes that — fixed fee, FCMA-qualified, and questions answered the day you ask them.
- Self-assessment filed accurately, well before the January deadline
- Allowable expenses identified — keep more of what you earn
- Your tax liability visible months in advance, not as a surprise
- Bookkeeping off your plate, cloud-based and current every month
No long-term contract. If it is not working after three months, you leave with clean books and nothing owed.

Sound familiar?
Still doing your own tax return in January?
Most London sole traders spend more time worrying about their self-assessment than actually running their business. Allowable expenses get missed. The tax bill arrives without warning. And somewhere in a drawer there is probably a receipt from eighteen months ago that should have been claimed. None of this is unusual — and none of it needs to carry on.
- Tax bill lands in January with no warning and no time to plan
- Allowable expenses missed because no one is checking your books regularly
- Hours lost every year on self-assessment you are not confident is right
What sorted looks like for a sole trader
Your books are current, your expenses are captured, and you know your tax position months before it is due. The January deadline becomes an administrative formality rather than a source of anxiety.
- Tax liability calculated early — time to plan, not just pay
- Expenses reviewed and claimed correctly every month, nothing left on the table
- Self-assessment prepared and filed by a chartered accountant, not guessed at
- Fixed, transparent fees — no surprises on the invoice either
What sole traders say after switching
These are verified Google reviews from clients who came to OD Accountants as individuals and small businesses — and stayed for years.
My other-half introduced me to Niall at OD Accountants and I have to say my finances are so much the better for it. Unlike my previous Accountants, Niall is far more hands-on, available for advice and able to care for me as an individual, rather than a faceless client. His fees are very reasonable and the money he has saved me more than covers them. If you need an Accountant who cares, Niall and OD Chartered Management Accountants are the way to go.
I've been there for years and Niall and his team go above and beyond the duties to provide accounting services but also general advices. They are always available if you need anything while charging very competitive prices. I could not recommend them enough.
What a sole trader engagement covers
A fixed-fee engagement built around the things sole traders in London actually need — not a one-size compliance package, and not a bill that grows every time you ask a question.
Self-Assessment and Personal Tax
Your annual self-assessment is prepared, reviewed and filed by a chartered accountant — not rushed through in January. Allowable expenses are identified properly across the year, so the return reflects your actual position rather than a conservative guess. You know your liability well before the payment deadline.
Included as standardCloud Bookkeeping Every Month
Day-to-day records are maintained through cloud accounting software, kept current and organised throughout the year. There is no year-end scramble to reconstruct twelve months of transactions from bank statements. Your income and expenses are visible whenever you need them — for tax planning, for lenders, or simply for your own clarity.
Cloud-first deliveryVAT and Making Tax Digital
If you are registered for VAT, returns are prepared and filed on time, and your records are kept MTD-compliant from day one. Your VAT threshold is monitored throughout the year — you will not cross it without knowing it is coming. If registration becomes necessary, the transition is handled without disruption.

Why London sole traders choose this firm
There are plenty of accountants in London. These are the things that are specific to OD Accountants — and that clients mention consistently after a year or more.
Questions answered when you ask
Multiple verified reviews describe the team as 'always available' and 'fast to respond' — not a support ticket system, not a week's wait for a callback. For sole traders who have a question about an invoice or an HMRC letter, that responsiveness is worth more than most features on a service list. You get a direct answer, in plain English, the same day.
Fees that pay for themselves
Clients consistently note that the tax savings identified by the firm more than cover the cost of the engagement — that is not a marketing line, it is verbatim from the Google reviews. For a sole trader with mixed income, untracked expenses or a self-assessment history that could be improved, the first year alone tends to demonstrate the value. Fixed fees mean no surprises on the invoice.
Chartered depth, not just compliance
Founder Niall O'Driscoll is a Fellow of the Chartered Institute of Management Accountants (FCMA, CGMA) with over ten years of freelance restructure and turnaround work behind him, including listed companies. That background is what a sole trader gets access to — not just a self-assessment filing service, but an accountant who understands the commercial picture and can advise on it when it matters.
Up and running in four straightforward steps
The process is designed to be as low-friction as possible. Most new clients are fully onboarded within a week of their first call.
Book a free discovery call
A short call — typically twenty minutes — to understand your situation, the services you need, and whether there is a good fit. No preparation required on your part. You will leave the call with a clear picture of what working together looks like and what it costs.
Receive a fixed-fee proposal
A straightforward proposal with a fixed monthly or annual fee, broken down by what is included. No ambiguity about what triggers an extra charge. If the scope changes, that conversation happens before the invoice, not after.
We handle the handover
If you are switching from another accountant or picking up books that have fallen behind, the transition is managed by the firm. Access to your previous records is requested, catch-up work is scoped and priced separately where needed, and your new cloud accounting setup is configured to the firm's standard stack.
Your books are off your plate
From onboarding onwards, bookkeeping is maintained, tax deadlines are tracked, and your self-assessment is handled well before January. You know your tax position throughout the year. The parts of running a business that used to take up Sunday evenings are handled — which is, frankly, the way it should be.
“Been with OD Accountants for over a year now. Niall and the team are brilliant. They helped me set up a company and get everything I needed in place to run my business. I'm a tricky client due to my 'digital nomad' status, but their advice…”
What sole traders usually ask first
Do you work specifically with sole traders, or is it mostly limited companies?
Both — a meaningful portion of the client base is sole traders and self-employed individuals, including freelancers, consultants, hospitality operators and internet resellers. The firm understands the specific position of a sole trader: mixed income sources, the interaction between personal and business finances, and the self-assessment filing obligations that come with it. You will not need to explain how being self-employed works before getting a useful answer.
What does a sole trader accounting package cost?
Fees are fixed and agreed upfront — clients consistently describe them as 'very reasonable' and 'competitive', and note that the tax savings identified typically more than cover the cost of the engagement. A free quote is available via the form on this page. The scope and cost depend on your turnover, whether you are VAT registered, and how much bookkeeping support you need — all of which is covered in the initial discovery call.
My books are behind and my last self-assessment may not have been filed correctly. Can you take that on?
Yes — this is a fairly common starting position. Catch-up bookkeeping is scoped and priced separately, and any concerns about prior self-assessments can be reviewed as part of onboarding. Where a prior return needs amending, that is handled directly with HMRC. The aim is to establish a clean baseline and move forward from there, without overstating the complexity of what needs doing.
Is there a long-term contract?
No. There is no long-term lock-in. If the arrangement is not working, you leave with your records in order and nothing further owed. The firm's client retention is built on results and responsiveness — verified Google reviews include clients who have been with the firm for seven, ten and eleven years. That is the model, not a contractual obligation to stay.
I work across multiple income streams — employed, freelance and some rental income. Can you handle all of that in one self-assessment?
Yes. Self-assessments with multiple income sources — employment income, self-employed income, rental income, dividends and overseas income — are handled as standard. The return is prepared to capture all sources correctly, with allowable expenses and reliefs applied across each. If your situation is genuinely complex, that is reflected in the fee quote, not discovered later.
How far in advance will I know what my tax bill is going to be?
With current bookkeeping in place, your tax liability is visible throughout the year — not just in December when the panic sets in. For sole traders with consistent income, a reasonable estimate is available as early as mid-year, with a firm figure well before the January payment deadline. That lead time is what makes tax planning possible, rather than just tax compliance.
