E-commerce accountants in Merton
If your Merton 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 West London and the £149 health check finds the errors before HMRC does.

Worth knowing
Rules that come up in this work
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.
Director's loan accounts
Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.
The VAT registration threshold
VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.
Corporation Tax rates and marginal relief
Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.
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
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 Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Questions
E-commerce Accountants questions from Merton
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.
Who accounts for VAT on marketplace sales?
For goods sold to UK consumers through an online marketplace, the marketplace accounts for the VAT if the seller is overseas or the goods are imported in consignments up to £135. A UK seller selling UK-held goods to UK customers accounts for their own VAT. Mixed situations are common and we separate them on every return.
How are imports treated?
Import VAT is charged when goods enter the UK and can be reclaimed as input VAT if you are registered, using postponed VAT accounting so nothing is paid at the border. Customs duty depends on the goods and origin and is a cost, not reclaimable. We make sure the C79 or postponed accounting statements are matched to the return.
What is in the £79 single-channel package?
Monthly bookkeeping reconciled to one marketplace or store's reports, software integration, and the annual accounts and tax return (Corporation Tax for a company or Self Assessment for a sole trader). It is for sellers under the £90,000 VAT threshold; once VAT registration is needed the £129 package applies.
Why does e-commerce bookkeeping cost more than ordinary bookkeeping?
Because a single payout from a marketplace bundles hundreds of sales, fees, refunds, advertising charges and reserves, and each has a different VAT treatment. Reconciling the payout to the underlying report is the job. Our fee is fixed by channels and VAT status rather than by transaction count for exactly this reason.
Do you have an office in Merton?
No. IGI Accounting is an online-only firm. We serve Merton 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 Merton as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is e-commerce accountants in Merton really the same price as elsewhere?
Yes. The fee published on this page is what a client in Merton 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.
