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.
The trading and property allowances
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
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.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
Questions
E-commerce Accountants questions from Thamesfield
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.
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.
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.
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.
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.
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.
