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.

Switching accountants

The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.

Closing a company

A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.

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 trading and property allowances

The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.

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.

Questions

Startup Accountants questions from Mottingham

What is SEIS/EIS advance assurance and do I need it?

Investors in qualifying early-stage companies get income tax relief of 50% (SEIS) or 30% (EIS) and capital gains exemptions, which makes raising much easier. Advance assurance is HMRC's confirmation in principle that your company qualifies, and most angel investors insist on it. Our £299 service prepares and submits the application.

What are the SEIS limits?

A company can raise up to £250,000 under SEIS within the first three years of trading, with gross assets under £350,000 and fewer than 25 employees. EIS allows up to £5 million a year and £12 million in total, for companies under seven years old with fewer than 250 employees. Trading activities must qualify; some are excluded.

When are a new company's first filings due?

The first confirmation statement is due within 14 days of the first anniversary of incorporation. The first accounts are due 21 months after incorporation. Corporation Tax is due nine months and one day after the first accounting period ends, and the first period is often longer than a year, which creates two CT600s. We handle the split.

Can I claim startup costs incurred before incorporation?

Yes. Pre-trading expenses incurred up to seven years before the company started trading, which would have been deductible if incurred while trading, are treated as incurred on the first day of trading. Keep the receipts. Equipment you bring in can be transferred to the company at market value.

What does the £59 Launch package include?

Company formation with the Companies House £100 fee passed on separately, Corporation Tax and PAYE registration, a registered office if you want one, cloud software set up, the first confirmation statement and the first set of accounts and CT600 filed. It is for founders who will keep their own books in the early months.

When do I need Grow or Scale?

Grow at £99 adds monthly bookkeeping and quarterly VAT returns, and suits most startups once transactions and VAT registration arrive. Scale at £149 adds payroll for founders and first hires with auto-enrolment, plus quarterly management accounts for the board or investors. You can move between packages at any month end.
