How much does a small business accountant cost?

It depends on your set-up and how much you hand over. For Making Tax Digital, published prices we found run from about £25 to £200 a month, with £45 to £150 typical. A limited company with payroll and VAT usually costs more than a sole trader with one income source. Ask each firm for a written quote.
