Online accountants vs the high street
Most local firms near Southwark quote low, bill by the hour and reserve the right to charge for every phone call. We built the opposite: written fixed fees agreed up front, unlimited questions inside the price, and a fully online workflow — no premises anywhere, so no premises priced into your fee in Southwark.
There's no office to fund in Southwark 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.

Southwark cis tax returns FAQs
How much CIS refund am I owed?
Most subcontractors have 20% deducted at source all year — usually more than their final tax bill once expenses and the personal allowance are counted. Refunds of £1,500–£3,000 are common, claimed through your Self Assessment.
How quickly will my refund arrive?
Once the return is filed, HMRC typically pays CIS refunds within 2–6 weeks. We file promptly after 6 April so the claim is in the queue as early as possible.
What is gross payment status?
It lets contractors pay you without CIS deductions — better cash flow. You need to pass HMRC's turnover and compliance tests; we assess whether you qualify and handle the application.
Do I need to visit an office in Southwark?
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 Southwark or anywhere else in South East London.
I searched "cis near me" — is this service really local to Southwark?
Southwark 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 Southwark town centre or the edge of South East London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my cis?
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.
The short version of the rules that matter
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.
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.
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.
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.
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 Southwark stopped being the differentiator the day filings went electronic.
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.
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.
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.
