In 2026, hiring a professional accountant is no longer just a compliance necessity. It delivers measurable business value for self-employed buyers and sole traders in Sussex. A UK-wide survey by Intuit QuickBooks of over 4,000 small businesses found that firms using accountants reported an average 11.5% increase in revenue, with sole traders seeing nearly 9% higher income compared with those handling accounts alone, highlighting a clear financial upside to professional support.
Research also shows that 66% of small businesses outsource at least some of their tax administration to qualified accountants, primarily to reduce errors and save time that they would otherwise spend on complex tax filings.
For self-employed homebuyers navigating Self-Assessment and Making Tax Digital (MTD) requirements, the right accountant can make financial planning easier, more accurate and more strategic.
