Expert Accounting for New Businesses

Accountants for startups work day to day with the reliefs and structures that define an early-stage company: SEIS and EIS advance assurance, R&D tax credits under the merged scheme, EMI option schemes, and investor-ready management accounts. A general high-street accountant may handle your year-end filing competently but rarely sees these schemes often enough to claim them confidently or defend them under an HMRC enquiry. The difference usually shows up as missed reliefs worth thousands, or as a cap table that needs expensive restructuring before a funding round.

Look for direct, recent experience with startups at your stage and in your sector, current ACA, ACCA, or CIMA qualification with professional indemnity insurance, and clear fixed-fee or capped pricing rather than open-ended hourly billing. Ask how many SEIS/EIS advance assurance applications and R&D claims they have filed in the last year, and whether they can support you through a funding round. We work with startups on exactly these criteria and come back with a fixed written quote so you can weigh the approach and fees before committing.

Startup accounting fees typically range from £150-£400 per month for basic compliance, with additional charges for specialist services like R&D tax credit claims (usually 15-25% of the credit obtained) or SEIS/EIS scheme setup (£1,500-£3,000). Many accountants offer fixed-price packages for the first year to help with cash flow planning. Annual accounts preparation costs between £800-£2,000 depending on complexity.

UK startups can access several HMRC reliefs including R&D tax credits under the merged scheme (20% of qualifying costs, or 27% for R&D-intensive SMEs, as a cash payment or corporation tax reduction), SEIS which allows 50% income tax relief for investors plus capital gains exemptions, and EIS which provides 30% relief on larger investment amounts. Business Asset Disposal Relief can also reduce capital gains tax to 18% on qualifying disposals made on or after 6 April 2026.

You must register for VAT when your taxable turnover exceeds £90,000 in a 12-month period (the threshold rose from £85,000 on 1 April 2024), but many startups register voluntarily earlier to reclaim VAT on startup costs and appear more established to clients. This is particularly common for B2B startups serving VAT-registered clients. If you mainly serve consumers, early registration adds 20% to your prices, so timing is crucial.

Whilst basic bookkeeping can be handled initially using software, specialist startup accountants provide crucial early-stage advice that can save thousands. They ensure you're structured correctly for tax efficiency, help claim all available reliefs, and avoid costly mistakes with HMRC. Having professional accounts from day one also improves your credibility with potential investors and lenders.

R&D tax credits allow qualifying companies to reduce their corporation tax bill or receive cash payments for research and development activities. Under the HMRC merged scheme (from April 2024), loss-making startups receive a cash payment of 20% of qualifying R&D expenditure, rising to 27% for R&D-intensive SMEs (where qualifying R&D exceeds 30% of total expenditure). Qualifying costs include staff costs, subcontractor fees, cloud and software directly used in R&D, and consumables. Many tech startups successfully claim these credits to improve cash flow during development phases.

SEIS (Seed Enterprise Investment Scheme) is for very early-stage companies with gross assets under £350,000, offering investors 50% income tax relief plus capital gains exemptions. EIS is for more established startups with gross assets under £15 million, providing 30% income tax relief. Both require advance assurance applications to HMRC. Most startups use SEIS initially then transition to EIS for later funding rounds.

Most successful startup-accountant relationships involve monthly check-ins during the first year, then quarterly meetings once systems are established. You should have immediate access for urgent queries about tax deadlines, HMRC correspondence, or investment structuring decisions. Many accountants offer unlimited email support and priority phone access as part of their startup packages.

Under Making Tax Digital requirements, you must maintain digital records of all business income and expenditure, VAT transactions (if registered), and employee payroll information. Records must be kept for at least 6 years. For startups claiming R&D credits or other reliefs, additional documentation proving qualifying activities and expenditure is essential.

If you're working from home, you can claim a proportion of household expenses (heating, lighting, insurance, mortgage interest) against business profits. Self-employed founders can use HMRC's simplified flat-rate method, which is £10 per month for 25–50 business-use hours, £18 for 51–100 hours, and £26 for 101 or more hours, or calculate actual costs based on business use percentage. Claiming mortgage interest or council tax relief may create capital gains tax implications when you sell, so professional advice is essential.

Start growth planning when you achieve consistent revenue, plan to hire employees, or seek external funding. Early planning prevents common pitfalls like inefficient tax structures or inadequate financial controls during rapid expansion. Professional guidance on timing VAT registration, employment obligations, and profit extraction strategies makes a material difference to your financial outcomes.
