What makes us different

Online accountants vs the high street

Most local firms near Southfields quote low, bill by the hour and reserve the right to charge for every phone call. We work the other way round: one fixed fee agreed in writing before anything starts, every question included, and the whole engagement handled online — which is exactly why we can serve Southfields at fees a walk-in office can't match.

There's no office to fund in Southfields 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.

Serving Southfields

The same service in Southfields as anywhere — by design

Southfields sits in South West London (SW18), 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.

Being in London, Southfields clients often come to us comparing against firms charging central-London rates for the same compliance work. The work is identical; the overheads aren't — and since we carry no premises anywhere, our fees don't care about postcodes.

Questions

Southfields 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 Southfields?

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 Southfields or anywhere else in South West London.

I searched "self assessment near me" — is this service really local to Southfields?

Southfields 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 Southfields 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 Southfields

Switching accountants is easier than you think

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.

Crypto is taxable — and visible

Disposing of crypto — selling, swapping one coin for another, spending it — is a capital gains event, and staking or mining income is usually income. Exchanges share data with HMRC, so the tax position exists whether or not it's been calculated.

Corporation tax dates work differently

New companies often have a long first accounting period, which can mean two corporation tax returns for one set of accounts. It's normal, but it's exactly the kind of thing that's cheaper to get right first time than to unpick.

Tax is a cash-flow event

Every tax bill is predictable months in advance — which makes tax the most plannable cost a business has. A separate tax savings account, fed a fixed percentage of every sale, converts January from a crisis into a transfer.

IR35 and working through a company

Status under IR35 turns on the reality of the engagement: control, substitution, mutuality of obligation. Contracts matter, but working practices matter more. A written status assessment for each engagement is cheap insurance.

What to actually look for in an accountant

A good accountant should be able to tell you, in plain English, what they'll do, when, and for exactly how much. Vagueness on any of the three is the tell. Everything else — size of firm, fancy office, distance from Southfields — is decoration.

Penalties escalate on a timetable

If a return is late because HMRC asked for one you don't actually need, it can sometimes be withdrawn entirely — penalties included. And where there's a genuine reasonable excuse, appeals succeed more often than people expect. The wrong move is ignoring the letters.

Your first year in business

Register with HMRC by the 5 October after your first tax year of trading, open a separate business account, and put a fixed slice of every payment aside for tax. Do those three things and your first January will be boring — the good kind.
