How it works

Freelancer Accountants from Sidcup, step by step

  1. Tell us your situation

    A short message or call about what you do and what needs filing. We ask the questions that determine the right package and nothing more.

  2. Fixed fee in writing

    You receive one price for the work, confirmed by email before anything starts. It does not change if the job takes longer than we expected.

  3. Send records, review the draft

    Records come by WhatsApp or email. We prepare the draft, explain the figures in plain English and answer your questions.

  4. We file, you get the receipts

    Once you approve and the fee is settled, we submit electronically and forward the HMRC or Companies House acknowledgement the same day.

Why IGI

What you get in Sidcup

No hourly rate and no surprise invoice. Sidcup clients know the fee for freelancer accountants 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 Sidcup get reminders at 60, 30 and 7 days before each date that applies to freelancer accountants.

Online only, UK based. There is no office in Sidcup 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.

Continuity matters in freelancer accountants: the person who prepared last year's work for your Sidcup business prepares this year's, and remembers what was agreed.

We explain freelancer accountants in the words Sidcup business owners use, not in accountant's shorthand, and we show our working so you can check it.

Nothing is filed for Sidcup 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.

Worth knowing

Rules that come up in this work

The Self Assessment calendar

Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.

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.

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.

Making Tax Digital for Income Tax

Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.

The VAT registration threshold

The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.

Corporation Tax rates and marginal relief

Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.

Salary versus dividends

Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.

Questions

Freelancer Accountants questions from Sidcup

What does the £45 sole trader package include?

Monthly bookkeeping from your bank feed with receipts captured by phone, a monthly summary showing profit and the tax accruing, your Self Assessment with the self-employment pages prepared and filed, payments on account calculated, and deadline tracking. Software is in your name and billed to you separately.

What does the £79 company package include?

Monthly bookkeeping, director payroll with RTI submissions, dividend paperwork, the annual statutory accounts and CT600 filed with Companies House and HMRC, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. Your personal Self Assessment is added at the published £129 if needed.

Should I be a sole trader or a limited company?

At profits under roughly £30,000 to £40,000 a sole trader is simpler and the tax saving from a company is small after the extra compliance cost. Above that, or where clients prefer to contract with a company or liability is a concern, incorporation can make sense. Our free comparison tool gives a first view and the starter session a definitive one.

What is the annual-only option?

For £229 a year we prepare your year-end accounts and Self Assessment from the records you keep yourself, whether in software or a spreadsheet. It suits freelancers with modest transaction volumes who are organised. If the records arrive as a shoebox, the sole trader accounts shoebox fee applies instead.

How much should I set aside for tax?

For a sole trader, roughly 20% to 30% of profit covers income tax and Class 4 National Insurance at basic rate, more at higher rate, plus payments on account in the first year they apply. We give you a specific monthly figure based on your actual profit each month, which is more useful than a rule of thumb.

What expenses can freelancers claim?

A proportion of home costs for the space and hours you work there, or HMRC's flat rate; equipment and software; professional subscriptions and insurance; training that maintains existing skills; business travel other than commuting; marketing and website costs; bank charges; and the business share of phone and internet. We review your categories every month.
