Frequently Asked Questions
Here are answers to common questions startup founders, tech entrepreneurs and early-stage business owners ask about specialist accounting.
What is SEIS Advance Assurance?
Advance Assurance is HMRC pre-approval confirming your share issue qualifies for SEIS relief. Most investors require it. Applications take 4 to 6 weeks and need a business plan and forecasts.
How does SEIS differ from EIS?
SEIS offers 50% income tax relief on £250,000 raise for companies under 3 years with under 25 employees. EIS offers 30% relief on £5 million for companies under 7 years.
Can pre-revenue startups claim R&D credits?
Yes. Loss-making R&D intensive startups can claim Enhanced R&D Intensive Support at 27% if R&D expenditure exceeds 30% of total expenditure. The cash credit provides vital runway for early-stage businesses.
What are EMI share options?
Enterprise Management Incentive options give tax-advantaged shares to key employees. Up to £250,000 unrestricted market value per employee. Strike prices set at agreed valuation defer income tax until exercise.
Are pre-trading expenses deductible?
Yes. Costs incurred up to seven years before trading begins are deductible when the trade starts. Common items include market research, legal fees, professional advice and equipment purchases.
Can ABM support startups nationwide?
Yes. ABM Chartered Accountants serves startups across England using secure cloud-based platforms, delivering specialist accounting to tech ventures, biotech founders, fintech companies and pre-revenue innovators.
