E-commerce accountants in Old Coulsdon

If your Old Coulsdon business sells through marketplaces, your own store or both, the hard part is not the bookkeeping, it is the VAT: when the marketplace accounts for it, when you do, how imports are treated, what happens with EU customers. We handle this for sellers across South London and the £149 health check finds the errors before HMRC does.

Worth knowing

Rules that come up in this work

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

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.

The trading and property allowances

Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.

Late filing penalties

Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.

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.

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.

Questions

E-commerce Accountants questions from Old Coulsdon

Can you handle multiple currencies?

Yes. Sales in foreign currencies are converted at the rate on the transaction date for the accounts and at HMRC's published rates for VAT, and the difference between those and what actually lands in your bank is recorded as exchange gain or loss. The software handles this once configured correctly.

How do refunds and returns affect my VAT and accounts?

A refund reverses the sale and the VAT on it in the period the refund is made, not the original sale. Returned stock goes back into inventory at cost. Marketplace reports show these separately and we reconcile them so that both the VAT return and the profit figure reflect actual net sales.

Do I need to register for VAT if the marketplace collects it?

Marketplace-collected VAT does not count towards your registration threshold, but your other sales do. Many sellers have a mix and cross the £90,000 threshold without realising. We monitor your rolling 12-month taxable turnover monthly and tell you when registration is approaching.

Should I trade as a sole trader or a company?

Many sellers start as sole traders and incorporate as profits grow. A company protects personal assets from supplier and platform disputes, and can be more tax efficient at higher profits, but adds compliance. Marketplaces also treat business accounts differently. We run the comparison for your numbers.

What is the marketplace VAT health check?

A one-off £149 review of your VAT registration, your marketplace tax settings, your treatment of imports and overseas sales, and a sample of recent returns against the rules. It produces a written report of errors found and what to do about them. Most sellers who have set things up themselves have at least one.

Can you reconcile my payment processor as well as the marketplace?

Yes. Card processors and payment gateways on your own store are integrated so that gross sales, fees and payouts post and reconcile automatically. The fee treatment, including VAT on processor fees, is configured at setup, which is where most self-built integrations go wrong.

Do you have an office in Old Coulsdon?

No. IGI Accounting is an online-only firm. We serve Old Coulsdon 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 e-commerce accountants is the same in Old Coulsdon as anywhere else in the country, and why there is nothing to visit and nothing to print.

Is e-commerce accountants in Old Coulsdon really the same price as elsewhere?

Yes. The fee published on this page is what a client in Old Coulsdon 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.
