Worth knowing
Rules that come up in this work
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
Corporation Tax rates and marginal relief
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
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.
Director's loan accounts
Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
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.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Questions
Startup Accountants questions from Castle Baynard
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.
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.
