South Harrow 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 South Harrow?
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 South Harrow or anywhere else in North West London.
I searched "self assessment near me" — is this service really local to South Harrow?
South Harrow 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 South Harrow town centre or the edge of North 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
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 you contract through your own limited company, IR35 asks whether you'd be an employee without it. For medium and large clients, the status decision is theirs; for small clients, it's still yours — and getting it wrong in either direction costs money.
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.
If you're a sole trader or landlord anywhere near the £50,000 income mark, Making Tax Digital will change your filing rhythm from 2026: four digital updates a year plus a final declaration. Clients who move their records to software early find the transition a non-event.
The businesses that struggle with tax bills rarely have a tax problem; they have a timing problem. Knowing the bill in September instead of January — which filing early gives you for free — is the difference between planning and scrambling.
The honest answer changes with your profits. At lower profits, sole trader simplicity usually wins; as profits grow, a limited company's mix of salary and dividends, corporation tax rates and liability protection starts earning its extra admin. We run the actual numbers before recommending either.
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.
HMRC requires records to be kept for at least five years after the filing deadline for the self-employed. Digital copies count. A cloud folder or app now beats a carrier bag of paper every time — for you and for any future enquiry.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in South Harrow, message us and we'll answer against your actual numbers.
