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.
Workplace pensions and auto-enrolment
Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.
Employer National Insurance
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
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.
The trading and property allowances
Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.
The VAT registration threshold
VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.
Questions
Startup Accountants questions from Cathedrals
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.
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.
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.
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.
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.
