Online accountants vs the high street
A high-street accountant in Central 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 Baker Street pays the same as everywhere else.
There's no office to fund in Baker Street 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.

We prepare, you check and approve, we submit — and you get the HMRC confirmation the same day it's filed.

Baker Street sits in Central London (NW1), and like everywhere we serve, it gets the identical service and fee as central London — because nothing about our work depends on where you are. What matters is your situation, your records and your deadlines; all three travel over WhatsApp just fine.
London clients in Baker Street 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.

Baker Street 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 Baker Street?
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 Baker Street or anywhere else in Central London.
I searched "self assessment near me" — is this service really local to Baker Street?
Baker Street 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 Baker Street town centre or the edge of Central 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.
Tax notes our Baker Street clients ask about most
Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most Baker Street clients who come to us in January still file on time; the records just need to arrive before the last week.
The first tax bill is the hardest because it can arrive with payments on account attached — up to 150% of the year's tax in one go. New businesses that save a quarter to a third of profits from day one never feel it.
The trading allowance means up to £1,000 of gross side income per year can be tax-free with no return needed. Above that, registration and reporting kick in — and platforms now report seller data to HMRC, so "under the radar" isn't a strategy any more.
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.
Most HMRC letters are routine — a statement, a code change, a reminder. The rule is simple: never ignore one, and never panic over one. Forwarded to your accountant the day it arrives, almost every letter is a five-minute job.
The capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.
Crypto traders rack up hundreds of taxable events without noticing, because every swap counts as a disposal. Specialist software plus the pooling rules turns the mess into a number; guessing does not.
Plenty of people incorporate too early because it "sounds established", then pay for accounts, confirmation statements and payroll they didn't need. The switch pays for itself at the right profit level — the trick is knowing yours.
