Every question in this cluster, answered
Do I need a specialist accountant as a dentist? Not a legal requirement, but useful. An associate dentist's limited company has to handle NHS pension deductions taken at source, superannuation certificates and the associate agreement, none of which a generalist accountant deals with daily.
What does an accountant for a SaaS or tech startup actually do? Beyond statutory accounts, a startup accountant handles deferred revenue recognition for subscriptions, R&D tax relief claims, EMI option scheme paperwork, and SEIS/EIS compliance statements, all areas where a generalist practice makes costly mistakes.
What should an accountant for an ecommerce seller cover? An ecommerce seller's accountant reconciles gross marketplace sales against fees and refunds, values stock correctly at the year end, and gets VAT right across Amazon, Shopify and international sales, none of which a bank feed alone will show you.
How does CIS accounting work for a construction business? A CIS-registered construction business has deductions taken from payments by contractors, applies the domestic reverse charge to VAT on most subcontractor invoices, and accounts for retentions held back until practical completion, all before the usual corporation tax and payroll work.
Should a property investor use a limited company for their portfolio? It depends on your tax position and plans. Companies get full relief for mortgage interest against rental profit, where individuals only get a 20% tax credit, but incorporating an existing portfolio triggers capital gains tax and SDLT unless a specific relief applies.
What does an accountant for a local shop, garage or café focus on? A local trading business with a till, casual staff and physical stock needs its daily takings reconciled against bank deposits, card settlements matched to the right day, stock movements tracked, and payroll run correctly for part-time and variable-hours staff.
