Clapham Junction 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 Clapham Junction?
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 Clapham Junction or anywhere else in South West London.
I searched "self assessment near me" — is this service really local to Clapham Junction?
Clapham Junction 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 Clapham Junction 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.
Things worth knowing before your next filing
The expenses rule is "wholly and exclusively" for the trade — which covers more than most people claim (proportionate home-working costs, business mileage, software subscriptions) and less than some hope (client entertaining, everyday clothing). Knowing the line is where the savings live.
If your last Self Assessment bill was over £1,000, HMRC usually asks for next year's tax in advance — half on 31 January, half on 31 July. It's the number-one cause of "why is my bill double?" calls, and it's manageable: if your income has dropped, the payments can be reduced with a claim.
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.
Some businesses register for VAT before they must — reclaiming input VAT can be worth it if your customers are VAT-registered themselves. Others should stay below deliberately. It's a real decision with real numbers, not a formality.
Miss 31 January and the £100 fine is automatic; three months later daily penalties start. If you're behind on a return, the maths almost always favours filing quickly over waiting — penalties grow on a timetable, and HMRC charges interest either way.
HMRC runs nudge-letter campaigns to crypto holders based on exchange data. If there are undeclared gains in past years, a voluntary disclosure is dramatically cheaper than waiting for the letter — penalties are scaled to cooperation.
Self Assessment lateness is priced in stages: £100 immediately, daily £10 penalties after three months (up to £900), then percentage-based charges at six and twelve months — all separate from interest on unpaid tax. The curve is designed to reward filing sooner, whatever the state of your records.
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.
