Why IGI
Working with Syon businesses
Clients in Syon are not a branch or a territory to us; they are files handled by the same team that serves the rest of the UK, at the same price. The fee you see is confirmed in writing before work starts. The dates you see are diarised and chased. And the person who prepares your first return is the person who prepares the next one.
A named person handles your self assessment tax returns from Syon and knows the file, so you are not re-explaining your business to a different helpdesk each time.
We serve Syon remotely by design: records by WhatsApp or email, drafts back for approval, filing electronic. The saving on premises is passed to you in the fee for self assessment tax returns.
Nothing for Syon is left to the last week. Each deadline relevant to self assessment tax returns is tracked from the day you join, with the next four shown on every page we send you.

Rules that affect most businesses here
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
Questions
Questions from Syon
Why are the fees the same in Syon 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 Syon 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.
Which services are available in Syon?
Every service on this page is available to businesses and individuals in Syon, 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.
I already have an accountant in Syon. 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.
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 Syon 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.
Is self assessment tax returns in Syon really the same price as elsewhere?
Yes. The fee published on this page is what a client in Syon 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.
Do you have an office in Syon?
No. IGI Accounting is an online-only firm. We serve Syon 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 Syon as anywhere else in the country, and why there is nothing to visit and nothing to print.
