Why IGI
Working with St Martin businesses
An online firm suits St Martin 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 St Martin, Cornwall clients the published fee and nothing more, with every submission approved by you before it goes.
We explain self assessment tax returns in the words St Martin, Cornwall business owners use, not in accountant's shorthand, and we show our working so you can check it.
Nothing is filed for St Martin until you have reviewed and approved it. You see the draft, you ask questions, you sign off, then we submit and send you the receipt.
No hourly rate and no surprise invoice. St Martin clients know the fee for self assessment tax returns before they send a single document, and it stays fixed.

Worth knowing
Rules that affect most businesses here
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
Workplace pensions and auto-enrolment
Every employer must assess its workers for automatic enrolment from the first employee's start date. Those aged 22 to State Pension age earning over £10,000 a year must be enrolled into a qualifying pension with minimum contributions of 8% of qualifying earnings, at least 3% from the employer, and a declaration of compliance made to the Pensions Regulator within five months.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
Questions
Questions from St Martin
What if my St Martin business is a partnership or an LLP?
Both are covered. Partnerships need a partnership return and a Self Assessment for each partner; LLPs file accounts with Companies House under company-style rules as well. We quote a fixed fee for the set based on the number of partners or members, and the process is the same as for any other client in St Martin, Cornwall: records in, draft out, approve, filed.
Do you work with businesses in South West that are not in St Martin itself?
Yes. Every place in South West has its own page on this site and the same fees apply throughout. The nearest-places list on this page links to them. Wherever in England your business is based, the service is identical because none of it depends on where you are.
How quickly do you respond?
In UK working hours, usually within a few hours and always the same working day. Each St Martin client has a named contact who knows the file. Outside working hours, WhatsApp and email messages are picked up first thing the next morning. In January and at other peak times we tell you your turnaround when you book rather than leaving you guessing.
Are your fees inclusive of everything?
Our fee covers the work described for the package. Companies House fees, such as £100 to incorporate or £50 for a confirmation statement, are charged separately and passed on at cost. Software subscriptions are in your own name. There is nothing else: no hourly extras, no charge for questions, and no additional year-end invoice for St Martin, Cornwall clients on monthly packages.
Do you have an office in St Martin?
No. IGI Accounting is an online-only firm. We serve St Martin, Cornwall 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 St Martin as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is self assessment tax returns in St Martin really the same price as elsewhere?
Yes. The fee published on this page is what a client in St Martin, Cornwall 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.
