How Much Does an Accountant Cost in Sussex?

If you are a small business owner, landlord or contractor in Sussex thinking about hiring an accountant, one of the first questions you will ask is: what will this actually cost me? It is a reasonable question, and one that too few accountants answer openly. Here is an honest guide to what you can expect to pay.

Why accountancy fees vary so widely

The cost depends on the size and complexity of your business, whether you are VAT-registered, how many employees you have, how organised your records are, and whether you opt for a fixed-fee or hourly arrangement.

Typical costs for common services

  • Self-assessment return (straightforward): £150–£350
  • Self-assessment with rental income or investments: £300–£600
  • Sole trader accounts and tax return: £400–£900 per year
  • Limited company accounts, CT600 and director's self-assessment: £900–£2,000+ per year
  • VAT returns: £100–£250 per quarter, or included in a package
  • Payroll (small team): £20–£60 per month

Fixed fees vs hourly rates

Many Sussex accountants now offer fixed monthly packages, which make budgeting easier and encourage you to ask questions freely. Hourly rates (typically £75–£200 depending on seniority) are more common for one-off advisory work.

What should be included?

When comparing quotes, confirm exactly what is and is not included. A low headline price may not cover VAT returns, payroll, or Companies House filings. Ask specifically whether bookkeeping, the director's personal tax return, and quarterly MTD IT submissions are included.

Is it worth it?

For most business owners in Sussex, a good accountant saves significantly more than they cost — through tax efficiency, avoided penalties, and freed-up time. The question is rarely whether to use an accountant; it is about finding the right one.
