Worth knowing

Rules that come up in this work

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.

Confirmation statements and identity verification

Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.

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.

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.

Payments on account

A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.

The Self Assessment calendar

The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.

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.

Questions

Startup Accountants questions from Coldharbour

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.

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.

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.

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.

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.

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.

Is startup accountants in Coldharbour really the same price as elsewhere?

Yes. The fee published on this page is what a client in Coldharbour, Greenwich pays and what a client in any other part of England pays.
