AccFirm offers a free initial consultation so you can assess the service with no obligation.

An accountant manages your financial records, prepares and files tax returns, produces annual statutory accounts, handles all HMRC and Companies House submissions, and provides strategic financial advice. AccFirm also provides proactive tax planning, cloud accounting setup, MTD compliance, and year-round advisory support not just year-end compliance.

A professional accountant saves significant time, reduces the risk of HMRC penalties, ensures every allowable expense is claimed, and provides access to year-round tax-saving advice. For most businesses, an accountant saves more in reduced tax liabilities and avoided penalties than the cost of the service itself making it one of the most financially sound investments a business owner can make.

You should consider professional accounting support when starting a business, incorporating a limited company, approaching the VAT registration threshold of £90,000, taking on your first employee, receiving income from multiple sources, or when your tax affairs become complex. AccFirm recommends engaging an accountant from day one to establish the right structure and avoid costly early mistakes.

Accountancy fees in the UK vary based on business type and the services required.

While it is not a legal requirement, the vast majority of sole traders use an accountant to prepare their Self-Assessment return, maximise allowable expenses, manage bookkeeping, and avoid HMRC penalties. From April 2026, sole traders with income above £50,000 will also be required to comply with Making Tax Digital for Income Tax Self Assessment (MTD for ITSA), making professional accounting support more valuable than ever.

A bookkeeper records and categorises daily financial transactions sales, purchases, and bank reconciliations. An accountant uses this data to prepare tax returns, statutory accounts, and financial reports, and provides strategic tax and business planning. AccFirm provides both bookkeeping and full accounting services, with a dedicated professional managing both functions for each client under a single fixed monthly fee.

Making Tax Digital (MTD) is HMRC’s programme requiring all businesses and individuals to maintain digital financial records and submit returns using HMRC-approved software. MTD for VAT is already mandatory for all VAT-registered businesses. MTD for Income Tax Self Assessment (MTD for ITSA) is being introduced from April 2026, initially applying to sole traders and landlords with income above £50,000, with further thresholds following. AccFirm ensures every client is fully MTD-compliant using Xero, QuickBooks, or FreeAgent at no additional cost.
