Worth knowing

Rules that come up in this work

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.

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

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

Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.

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

Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.

Questions

Startup Accountants questions from Carshalton South and Clockhouse

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.

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.

Can I switch to you from another accountant mid-year?

Yes. We request your records and professional clearance from the previous firm, pick up the bookkeeping where they left off and take over the filings. There is no charge for the switch and the first month's fee is the same as any other.

What if the startup fails?

Then the company needs to be closed properly: final accounts, final CT600, deregistration from VAT and PAYE, and a strike-off application or, if there are debts it cannot pay, a formal insolvency process. Our strike-off service with final accounts is from £349. SEIS investors can claim loss relief, which softens their outcome.

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.

Do you have an office in Carshalton South and Clockhouse?

No. IGI Accounting is an online-only firm. We serve Carshalton South and Clockhouse and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically.

Is startup accountants in Carshalton South and Clockhouse really the same price as elsewhere?

Yes. The fee published on this page is what a client in Carshalton South and Clockhouse 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.
