Worth knowing

Rules that come up in this work

Switching accountants

You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.

Closing a company

Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.

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

Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.

Record keeping

HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.

Allowable expenses

The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.

Crypto records and reporting

Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.

Questions

Startup Accountants questions from South West London

Do I need a separate business bank account?

Legally the company must have its own account because it is a separate person from you; using a personal account mixes funds and creates director's loan problems. Digital business banks open accounts quickly for new companies, and we connect the feed to your software as part of setup.

What do investors expect to see in the accounts?

Clean, current bookkeeping; a cap table that matches Companies House; founder payments properly documented; VAT and PAYE up to date; and management accounts showing runway. Due diligence on a seed round routinely finds undocumented director's loans and unfiled confirmation statements, both of which cost time at exactly the wrong moment.

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.

Should I register for VAT before I have to?

If your customers are VAT-registered businesses, early voluntary registration lets you reclaim VAT on setup costs with no real cost to customers. If you sell to consumers, registration adds 20% to your price or cuts your margin, so waiting until the £90,000 threshold is usually better. We model it for your business.

How should co-founders be paid?

Early on, often not at all, with equity as the reward. Once the company can afford it, a modest salary through payroll keeps National Insurance records intact and is deductible. Dividends require distributable profits, which loss-making startups do not have. Director's loans are a trap. We set the structure to suit the cash position.
