Why IGI
Working with Clapham Common businesses
We built the service around what business owners in places like Clapham Common actually complain about: not knowing what the accountant will charge, finding out about a deadline after it has passed, and receiving a set of accounts with no explanation. Each is fixed by design: fixed fees, deadline tracking shown on every page, and a plain-English summary with every draft for Clapham Common clients.
No hourly rate and no surprise invoice. Clapham Common clients know the fee for self assessment tax returns before they send a single document, and it stays fixed.
We work to the HMRC and Companies House calendar, not an appointment diary. Clients in Clapham Common get reminders at 60, 30 and 7 days before each date that applies to self assessment tax returns.
Online only, UK based. There is no office in Clapham Common to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Rules that affect most businesses here
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
Late filing penalties
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Questions
Questions from Clapham Common
Which services are available in Clapham Common?
Every service on this page is available to businesses and individuals in Clapham Common, at the fee shown. Core compliance work, accounts, tax returns, bookkeeping, VAT, payroll and company formation, is listed with its own local page. Specialist services such as R&D, crypto tax and HMRC enquiry support are national services delivered the same way from anywhere in the UK.
Why are the fees the same in Clapham Common as in London?
Because the cost of an accountant is mostly premises and that is a cost we do not have. The work is done online by UK-based staff, so a client in Clapham Common pays exactly the published fee, as does a client in central London or a Highland village. The fee is confirmed in writing before anything starts.
Can you deal with HMRC and Companies House for me?
Yes. Once you authorise us as your agent, HMRC and Companies House correspond with us about the filings we make for your Clapham Common business, and we can see your accounts and respond on your behalf. Authorisation is free and takes a few days to activate. Routine correspondence about work we have filed is handled at no extra charge.
I already have an accountant in Clapham Common. How hard is it to switch?
It takes about two weeks and costs nothing extra. You authorise us, we write to your current accountant for professional clearance and your records, and we transfer the agent authorisations. We pick up the next filing without a gap. You do not need to wait for a year end, and we tell you honestly if switching mid-job would be awkward.
Do you have an office in Clapham Common?
No. IGI Accounting is an online-only firm. We serve Clapham Common and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for self assessment tax returns is the same in Clapham Common as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is self assessment tax returns in Clapham Common really the same price as elsewhere?
Yes. The fee published on this page is what a client in Clapham Common pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
