E-commerce accountants in Streatham

If your Streatham 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

Closing a company

Striking off a company is cheap but must be done in order: stop trading, file the final accounts and CT600, pay the tax, close VAT and PAYE, distribute the remaining assets, close the bank account, then apply. Anything left in the company at dissolution passes to the Crown. Distributions up to £25,000 are taxed as capital gains; above that a formal liquidation is usually needed to keep capital treatment.

Confirmation statements and identity verification

The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.

CIS deductions

CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.

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.

Payments on account

Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.

Questions

E-commerce Accountants questions from Streatham

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.

I sell to EU customers. What VAT applies?

Since 2021 sales of goods to EU consumers are exports from the UK, zero-rated here, with EU VAT due in the customer's country. The EU's Import One Stop Shop lets you account for consignments under €150 through one registration. Above that, local registration or the customer paying on delivery. We advise on the right route for your volumes.

When do I need the inventory package?

When you hold meaningful stock. Without inventory accounting, the cost of goods purchased is expensed when bought, which distorts profit between periods and misstates the balance sheet. The £179 package tracks stock, calculates cost of sales and values closing stock, which lenders, investors and HMRC all expect from a stock-holding business.

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.

Do you have an office in Streatham?

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

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

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