Chelsea Harbour 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 Chelsea Harbour?
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 Chelsea Harbour or anywhere else in West London.
I searched "self assessment near me" — is this service really local to Chelsea Harbour?
Chelsea Harbour 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 Chelsea Harbour town centre or the edge of 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.
Tax notes our Chelsea Harbour clients ask about most
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.
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.
Compliance checks are usually specific: one return, one figure, one question. Answered promptly and with evidence, most close quickly. The expensive enquiries are the ones that started as unanswered letters.
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.
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.
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.
The best time to switch is after a filing, but it works at any point in the year. What matters is not letting a looming deadline stop you: a new firm can usually pick up an in-flight year faster than you'd think.
The tax-free dividend allowance is down to £500, so almost any director taking dividends now pays some dividend tax — and needs a Self Assessment return to report it. The classic small-salary-plus-dividends strategy still works; it just needs actual planning rather than folklore.
