Definition of Accountant
An accountant is a financial professional who prepares, examines, and analyses financial records for individuals and businesses. In the UK, accountants help with tax compliance, business planning, and financial management.
There are different types of accountants: Chartered Accountants (ACA/FCA from ICAEW, CA from ICAS), Certified Accountants (ACCA), and Chartered Management Accountants (CIMA). Each has different specialisations, though for personal and small business tax matters, any qualified accountant can assist.
Accountants can submit Self Assessment returns on your behalf using HMRC's agent services, represent you in tax enquiries, and provide advice on tax planning within legal boundaries. Their fees are tax-deductible for businesses.

How Accountant Affects Your Tax
A good accountant can save you more in tax than their fees cost. They stay up to date with tax law changes, ensure you claim all allowable expenses, help avoid penalties from errors, and can represent you if HMRC opens an enquiry. For complex tax situations (property income, self-employment, capital gains), professional advice is often worthwhile.
