What makes us different

Online accountants vs the high street

Traditional firms around South West London still run on hourly billing, office appointments and fees you discover after the work. 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 St. Margarets and North Twickenham pays the same as everywhere else.

You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Questions

St. Margarets and North Twickenham 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 St. Margarets and North Twickenham?

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 St. Margarets and North Twickenham or anywhere else in South West London.

I searched "self assessment near me" — is this service really local to St. Margarets and North Twickenham?

St. Margarets and North Twickenham 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 St. Margarets and North Twickenham town centre or the edge of South West 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.

Worth knowing

Tax, briefly — the parts that affect St. Margarets and North Twickenham

Penalties escalate on a timetable

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.

IR35 and working through a company

Inside-IR35 and outside-IR35 engagements need different setups — sometimes umbrella, sometimes the company, sometimes both across a year. Contractors who plan this per-engagement keep more and worry less.

Landlord tax has its own rules

Selling a rental property triggers capital gains tax with a tight reporting window — UK residential sales must be reported and the tax paid within 60 days of completion. It's one of the easiest deadlines in the whole system to miss, and one of the most penalised.

Allowable expenses: claim what's yours

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 VAT registration threshold

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.

Dividends: the allowance is small now

The best salary-dividend mix moves with each year's thresholds and your other income. Setting it once in April — rather than guessing through the year — is one of the simplest pieces of planning a director can do.

Crypto is taxable — and visible

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.

When HMRC writes to you

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.

General guidance, not personal advice — thresholds and dates change. For advice on your own position in St. Margarets and North Twickenham, message us and we'll answer against your actual numbers.
