Startup Accountants UK

Compare UK accountants for startups — company formation, SEIS/EIS, R&D tax credits, and scaling advice for early-stage businesses.

Startups need accountants who understand company formation, share schemes, SEIS and EIS relief, R&D tax credits, and cash-flow during early growth. The right startup accountant helps you choose the right structure (sole trader vs limited company), set up MTD-compatible software from day one, and plan for funding rounds and HMRC compliance as you scale.

Frequently asked questions

Do startups need an accountant from day one?

Not legally, but most founders hire an accountant before or shortly after incorporation to set up proper records, register for taxes, and avoid costly mistakes with VAT, payroll, and Companies House filings.

How much does a startup accountant cost?

Startup packages typically start from £59–£99 per month for basic limited company compliance. Firms offering R&D tax credit claims, SEIS/EIS advice, or investor-ready accounts charge £100–£149+ monthly.

Should a startup be a sole trader or limited company?

Limited companies offer liability protection and tax efficiency above roughly £30,000 profit. Sole traders suit very early-stage testing with minimal revenue. An accountant can model both structures for your situation.

Can an accountant help with R&D tax credits?

Yes. Specialist startup accountants identify qualifying R&D expenditure and submit claims under the SME or RDEC schemes. Successful claims can return 14–33% of qualifying costs as tax relief or cash credits.
