Streatham 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 Streatham?
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 Streatham or anywhere else in South London.
I searched "self assessment near me" — is this service really local to Streatham?
Streatham 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 Streatham town centre or the edge of South 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
Limited companies in CIS reclaim differently to sole traders — through payroll or the company tax return rather than Self Assessment. Plenty of construction companies sit on refundable deductions without realising; a quick review of the CIS position often pays for itself immediately.
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.
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.
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.
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.
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.
UK residential property sales have their own regime: report and pay within 60 days of completion, separately from Self Assessment. Other gains report annually. Mixing up the two timetables is a common and expensive mistake.
Compare accountants on the things that bite later: is the fee fixed and written down, what exactly is included, who does the work, how fast do they answer in January. Proximity to Streatham stopped being the differentiator the day filings went electronic.
