Worth knowing

Rules that come up in this work

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

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

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

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.

Director's loan accounts

A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.

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.

Questions

E-commerce Accountants questions from Cannon Hill

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.
