Why IGI

Working with St James's businesses

An online firm suits St James's 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 James's 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 James's business owners use, not in accountant's shorthand, and we show our working so you can check it.

Nothing is filed for St James's 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 James's clients know the fee for self assessment tax returns before they send a single document, and it stays fixed.

Rules that affect most businesses here

Switching accountants

Changing accountant is simpler than most people fear. You authorise the new firm, which writes to the old one for professional clearance and your records; the outgoing accountant must hand over your own documents and usually does within two weeks. The new firm registers as your agent with HMRC and picks up the next filing. There is no need to wait for a year end.

Closing a company

A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.

Employer National Insurance

Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.

Workplace pensions and auto-enrolment

Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.

Dormant companies

Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.

Questions

Questions from St James's

What if my St James's 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 James's: records in, draft out, approve, filed.

Do you work with businesses in Central London that are not in St James's itself?

Yes. Every place in Central London 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 James's 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 James's clients on monthly packages.

Do you have an office in St James's?

No. IGI Accounting is an online-only firm. We serve St James's 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 James's as anywhere else in the country, and why there is nothing to visit and nothing to print.

Is self assessment tax returns in St James's really the same price as elsewhere?

Yes. The fee published on this page is what a client in St James's 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.
