What we do for Middlesex and what it costs
All 26 services below are available to Middlesex clients at the published fee. Every fee is fixed and confirmed in writing before work starts.
Why IGI
Working with Middlesex businesses
An online firm suits Middlesex because the things that matter in accounting, accuracy, deadlines, clear explanations and a known price, do not depend on geography. What does depend on geography is overhead, and by not carrying it we charge Middlesex clients the published fee and nothing more, with every submission approved by you before it goes.
A named person handles your self assessment tax returns from Middlesex and knows the file, so you are not re-explaining your business to a different helpdesk each time.
We serve Middlesex 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 Middlesex 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.

Worth knowing
Rules that affect most businesses here
CIS deductions
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
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.
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.
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 Middlesex
Why are the fees the same in Middlesex 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 Middlesex 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 Middlesex?
Every service on this page is available to businesses and individuals in Middlesex, 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 Middlesex. 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 Middlesex 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 Middlesex really the same price as elsewhere?
Yes. The fee published on this page is what a client in Middlesex 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 Middlesex?
No. IGI Accounting is an online-only firm. We serve Middlesex 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 Middlesex as anywhere else in the country, and why there is nothing to visit and nothing to print.
