E-commerce accountants in Carshalton Central

Worth knowing
Rules that come up in this work
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
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
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
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.
Salary versus dividends
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
Questions
E-commerce Accountants questions from Carshalton Central
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 Carshalton Central?
No. IGI Accounting is an online-only firm. We serve Carshalton Central 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 Carshalton Central as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is e-commerce accountants in Carshalton Central really the same price as elsewhere?
Yes. The fee published on this page is what a client in Carshalton Central 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.
