Online accountants vs the high street
A high-street accountant in South London typically bills by the hour, meets by appointment and prices each extra question. Our model inverts that: the fee is fixed and written down before work begins, questions are part of the service rather than billable events, and everything happens online — the reason Waterloo pays the same as everywhere else.
There's no office to fund in Waterloo and no office to visit: records travel through our secure portal or WhatsApp, approvals happen on your phone, and filings go to HMRC and Companies House electronically. You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Whether your business trades from Waterloo itself or you simply live there and work everywhere, the tax rules are national — and so are we. Waterloo clients get the same preparers, the same fixed fees and the same deadline tracking as every other town on this site.
London clients in Waterloo tend to arrive with more moving parts — employment plus side income, shares, property. That's fine: the fixed quote covers your actual situation, agreed before we start, however many supplementary pages it needs.

Waterloo self assessment tax returns FAQs
What does the £129 fee include?
Preparation and online filing of your full SA100 return, including the supplementary pages your situation needs. If your return is more complex — rental income, capital gains — the packages above show the fixed price, and we confirm it in writing before starting.
I've missed the deadline — can you still help?
Yes. Late returns are common and fixable: we prepare and file the outstanding return quickly, and where there's a reasonable excuse we help you appeal penalties. The sooner it's filed, the sooner the penalties stop growing.
What records do I need to send you?
Income records (invoices, statements, P60/P45 if employed), expense records, and any letters from HMRC. Not sure what counts? Send what you have through the portal and we'll tell you exactly what's missing — chasing paperwork is part of the job.
Do I need to visit an office in Waterloo?
No — there's nothing to visit and nothing to print. We're an online firm: records go through our secure portal or WhatsApp, and everything is filed electronically. It works the same whether you're in Waterloo or anywhere else in South London.
I searched "self assessment near me" — is this service really local to Waterloo?
Waterloo is fully covered, yes. The work is done online, which in practice means more local than an office: same-day replies instead of appointment slots, and the same published fixed fee whether you're in Waterloo town centre or the edge of South London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my self assessment?
Bohzo Accountants — a trading name of Bohzo Ltd, a registered UK company (No. 15031604). You get a named contact, a fixed fee in writing, and nothing is filed until you've reviewed and approved it.
How do your fixed fees work?
You tell us your situation, we quote one fixed price in writing before any work starts, and that price never changes mid-job. If your case is unusually complex we'll say so up front and agree a different fixed price — but the fee is always agreed before we begin, never after.
Things worth knowing before your next filing
Most self-employed people under-claim. Use of home, mileage at HMRC's approved rates, phone and broadband apportionment, trade subscriptions, training that updates existing skills — legitimate deductions left on the table add up to real tax overpaid year after year.
The July payment on account is the forgotten deadline: no return is due, but money often is. We diary it for every client it applies to, because HMRC charges interest from the day it's late even though nothing was "filed" late.
Company deadlines run off your accounting year end, not the tax year: corporation tax is payable nine months and one day after year end, and the CT600 return is due twelve months after. Confusingly, the payment is due before the return — a sequencing quirk that catches new directors.
People stay with the wrong accountant for years because switching feels disruptive. In practice the profession has a standard handover process — clearance letters, copies of prior returns and working papers — and the new firm drives it, not you.
HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.
The £90,000 VAT threshold is measured over any 12-month rolling window, so a strong few months can tip you over mid-year. There's a 30-day window to register once you cross it; miss that and HMRC can backdate the liability to when you should have registered.
Can't pay the bill by the deadline? File anyway. Filing and payment are penalised separately, and HMRC's Time to Pay arrangements can spread the bill — but only once the return is in. Not filing because you can't pay turns one problem into two.
HMRC requires records to be kept for at least five years after the filing deadline for the self-employed. Digital copies count. A cloud folder or app now beats a carrier bag of paper every time — for you and for any future enquiry.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Waterloo, message us and we'll answer against your actual numbers.
