Worth knowing
Rules that come up in this work
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
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.
Allowable expenses
Expense claims are where a return is won or lost in an enquiry. The test is wholly and exclusively for the trade; where a cost is mixed, the business proportion can be claimed if it can be identified. Capital items such as equipment and vans are relieved through capital allowances rather than as expenses, except under the cash basis where they are simply deducted when paid.
Questions
Startup Accountants questions from St. Mark's
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.
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.
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.
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.
