Self Assessment fees
Use this table as a transparent starting point. It uses our current published prices or an official government amount, not an unsupported market average. We confirm professional fees and responsibilities in writing after understanding the company, its records and its filing position.
| Service or example | Price or amount | What it means |
|---|---|---|
| One director return within a package | Included from £89 + VAT/month | Included with the company compliance scope |
| Additional director Self Assessment | From £150 + VAT | Straightforward additional return |
| Complex disclosures or overdue years | Quoted first | Price depends on records, years and income sources |
Professional fees exclude VAT unless stated. “From” prices require a confirmed scope. Tax examples are illustrative and are not a quote or personal tax calculation.
What changes the final cost?
Price follows the work required, not a keyword or postcode. A clean, reconciled record set generally takes less time than incomplete books. Before quoting, we identify the recurring filings, who keeps the records and whether earlier periods need attention. The main factors for this service are:
- self-employment or rental accounts
- capital gains and overseas income
- missing records or overdue returns
- number of income sources and relief claims
A proposal then separates recurring compliance from optional advice and one-off correction work. That makes like-for-like comparison easier and reduces the chance of a cheap headline fee becoming an unexpected bill later.
What is included, and what is separate?
Normally included in scope
- Preparation, review and online filing are included in the agreed return scope.
- We provide the calculation and payment deadline.
Check or quote separately
- HMRC investigation work is separate.
- Advice on complex transactions is quoted before work starts.
The engagement letter is the definitive record of what we will do, what information the directors must provide and when. If your requirements change—for example, the company registers for VAT, hires staff or begins selling through additional platforms—we discuss the revised work before changing the fee.
How to compare accountant quotes properly
Put each quote beside the same list of deliverables: statutory accounts, CT600, confirmation statement, director Self Assessment, bookkeeping, VAT, payroll and scheduled advice. Check whether transaction limits, software, Companies House charges, catch-up work and HMRC correspondence are included. Also ask who reviews the work and how quickly questions are normally acknowledged.
For a UK limited company, the lowest figure is not necessarily the lowest total cost. Missing bookkeeping, payroll or director-tax work may be billed later, while poor records can obscure tax deadlines and cash requirements. Choose a scope that matches the company now and can be reviewed as it changes. Our full limited company fees and packages remain the central source for our current recurring prices.
