Sound familiar?
Still not sure what your tax bill is going to be?
Self assessment is one of those things that sits at the back of your mind from April and lands on your desk in January. By then, the numbers are what they are. There is no time to plan around them, no opportunity to reduce the liability, and a looming penalty if the filing is late. A fair number of people also file their own return and quietly wonder if they have done it right.
- Tax bill arrives in January with no time to plan around it
- Allowable expenses missed because nobody reviewed the records properly
- Self-filing with low confidence the return is actually correct
What a handled return looks like
The return gets prepared well before the deadline, with a clear view of the liability and what went into it. You are not guessing. The workings are explained in plain English, any deductions you are entitled to are applied, and the filing goes to HMRC with a chartered management accountant's name behind it.
- Tax liability confirmed and explained months before January
- Every allowable deduction reviewed — personal and business receipts included
- Return prepared and filed by a qualified accountant, not you
- Fixed fee — no surprise invoice after the work is done
What clients say about personal tax work
Directors, sole traders and individuals across London and the UK. Fixed fees, tax savings that typically outweigh the cost, and an accountant who actually explains the numbers.
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 the self assessment service covers
One fixed fee covers the preparation, review and filing of your return. No per-query charges, no last-minute add-ons, no chasing you for information we could gather ourselves.
Return Prepared and Filed
Your self assessment return is prepared by a chartered management accountant working from your records, bank statements and any other income sources. The return is reviewed before filing, and you receive a clear summary of what was included and why. HMRC receives an accurate, on-time submission.
Included as standardDeductions Reviewed in Full
Allowable expenses, pension contributions, charitable giving, employment costs — everything that reduces the liability is identified before the return is completed. Most clients find the savings more than cover the fee. Nothing is left in the drawer because it seemed too small to mention.
Included as standardTax Planning Around the Filing
Knowing what you owe is useful. Knowing it in October rather than January is considerably more useful. Where there is scope to plan — timing of income, use of allowances, pension contributions before the tax year closes — that conversation happens as part of the engagement, not as an upsell.
Available on requestClients across a decade of returns
Directors, contractors, consultants, digital nomads and small business owners. Many have been clients for years. The pattern in the reviews is consistent: responsive, hands-on and the savings cover the cost.
Well-Informed and Confident About Financial Data
“The service from OD has been excellent, as has their advice. It's great to have access to a financial team who can guide us with such confidence and seamlessly integrate with our internal team. We always feel well-informed and confident about our financial processes and data. Highly recommend.”
Helped a Tricky Digital Nomad Client
“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…”
Supportive, Clear and Always on the Phone
“Niall and his team are supportive, clear and directional accountants who have supported our small business staff up. They're always on the end of the phone to advise and assist and provide a top service for our accounting needs. Plus they're just nice people which helps too!!”
Why this firm over a general practice
There is no shortage of accountants who will file a self assessment return. The difference is whether yours comes with a qualified eye on the numbers, a fixed price and someone who picks up the phone.
FCMA Qualification Behind the Work
Founder Niall O'Driscoll is a Fellow of the Chartered Institute of Management Accountants — not a bookkeeper who added tax returns to the menu. That qualification matters when the return involves multiple income streams, rental income, overseas earnings or employment alongside self-employment. The complexity does not slow the process down.
Questions Answered the Day You Ask
Verified Google reviews from clients going back over a decade consistently describe the same thing: always available, fast to respond, questions answered without being passed around. For something as time-sensitive as self assessment — where a query about an allowance in October is far less stressful than the same query in January — that responsiveness matters.
Savings That Typically Cover the Fee
Multiple long-term clients note in their reviews that the tax savings identified more than cover what they pay. That is not a guarantee, but it is a consistent pattern across directors, sole traders and individuals who switched from doing it themselves or from a less attentive firm. A fixed fee means you know the cost before you commit.
Up and running in four straightforward steps
From first contact to filed return, the process is designed to take as little of your time as possible. Most clients find the handover takes under an hour.
Book a discovery call
A short call — usually twenty minutes — to understand your situation. Income sources, last year's position, anything complicated. You will leave knowing what the engagement covers and what the fixed fee is.
Send us your records
Bank statements, payslips, invoices, P60 — whatever applies. You do not need them in a particular format. If the records are incomplete or behind, that is a common starting point and handled as part of the work.
We prepare the return
The return is prepared, all deductions are reviewed, and a draft is sent to you with a plain-English summary of what has been included and what you owe. You approve it. We file it.
Filed, confirmed, done
HMRC receives the return, you receive confirmation, and you know your exact tax liability well ahead of the payment deadline. No last-minute panic, no late-filing penalty, no wondering if the number is right. Which is, frankly, the way it should be.
“As a new start up and having never dealt with an accountant, Niall at OD Accountants has been very welcoming and supportive. All our prior queries and issues have been resolved, and he is always available to meet the needs of our team.”
Things people usually ask before starting
I have multiple income sources — employment, freelance work and some rental income. Can you handle all of that in one return?
Yes, and that is a fairly standard picture for the clients who come to us. Employment income, self-employment, rental income, dividends from a limited company, overseas income — all of it goes into a single self assessment return. The more sources there are, the more important it is to have someone review the allowances and deductions that apply to each, rather than filing based on the headline numbers alone.
What does the self assessment service cost, and what is included in the fee?
Fees are fixed and confirmed upfront before any work starts — no hourly billing, no per-query charges. The fee covers preparation of the return, a full review of allowable deductions, a plain-English summary of the liability, and the filing itself. For returns involving multiple income streams or complexity, the fee reflects that. Clients consistently describe the pricing as reasonable, and the savings identified typically more than cover the cost.
I have not filed a return for a couple of years and my records are in a poor state. Can you still help?
That is a common starting point, not an unusual one. Late or missing returns are handled as a separate piece of work from the current year, and HMRC's late-filing penalty regime is navigable if you engage early rather than waiting for a demand. The first thing to do is establish exactly what is outstanding, what records exist, and what needs to be reconstructed — which is something we can assess on a short call at no cost.
Is there a long-term contract? What happens if I want to leave?
No long-term contract. Self assessment is an annual engagement — you are not locked in beyond the current return. If you decide to move to another accountant after the first year, your records are in order and we transfer them cleanly. There is nothing owed and no exit fee.
I am a company director with a salary and dividends. Do I need a self assessment return?
Yes — directors who receive dividends outside of the basic rate band, or whose total income exceeds the threshold for self assessment registration, are required to file. The return needs to capture both the PAYE salary and the dividend income accurately, and there are specific allowances that apply to each. Missing the dividend allowance or incorrectly reporting PAYE income are among the more common errors on director returns filed without professional support.
When is the best time to start the process if I want visibility on my tax bill before January?
As soon as the tax year ends in April, it is possible to prepare and file the return — and for most clients, that is worth doing. Filing early means you know the liability in May or June rather than January, which gives you time to plan payments, adjust pension contributions if there is still scope, and avoid the cognitive overhead of a deadline approaching. The January rush is optional. Most clients who have filed early once do not go back.
