How Much Does an Accountant Cost for Self Assessment?
The cost of an accountant for Self Assessment depends on how complex your tax return is. A simple employment and tax refund return should cost less than a return involving self-employment, rental income, capital gains, dividends, foreign income, CIS deductions or director income.
Introduction
The cheapest option is not always the best one. A good Self Assessment accountant should help you report income correctly, claim valid expenses, avoid common mistakes and submit the return on time.
This guide explains what affects Self Assessment accounting fees and what you should expect from a professional service.
Why Self Assessment costs vary
Self Assessment tax returns are not all the same. Some people only need to report one source of income, while others have several income streams and more complicated tax treatment.
The cost usually depends on:
- number of income sources
- quality of your records
- whether you are self-employed
- whether you have rental income
- whether you have capital gains
- whether you are a company director
- whether CIS deductions apply
- whether foreign income applies
- whether previous returns need correcting
- how close you are to the deadline
A return with clean records is usually easier and cheaper to prepare than one where the accountant needs to reconstruct income and expenses from bank statements.
Simple Self Assessment returns
A simple Self Assessment return may include employment income, bank interest, small dividends, pension contributions or basic tax relief claims.
This type of return is usually straightforward if all records are available, such as P60, P45, P11D, bank interest certificates and pension contribution details.
Self-employed tax returns
Self-employed individuals usually need to report business income and allowable expenses. This can include invoices, sales records, receipts, mileage, home office costs, software, phone, internet, marketing, insurance and subcontractor costs.
The fee may be higher if bookkeeping has not been done during the year. If the accountant needs to organise records before preparing the return, that adds time.
Landlord tax returns
Landlord tax returns can cost more than simple returns because property income often involves mortgage interest, letting agent statements, repairs, insurance, service charges, joint ownership, capital costs and sometimes Capital Gains Tax.
If you own more than one property, the work usually increases because each property may need separate income and expense records.
Director Self Assessment returns
Company directors may need Self Assessment support if they receive salary, dividends, benefits, rental income, investment income or have director’s loan account matters.
Director tax returns should be reviewed alongside the company accounts, payroll, dividends and personal tax position.
What should be included in the accountant’s fee?
A professional Self Assessment service should usually include:
- review of your income sources
- review of allowable expenses
- preparation of the tax return
- tax calculation
- advice on payments on account
- submission to HMRC
- confirmation of amount due
- guidance on payment deadline
- basic HMRC correspondence support
Make sure you know what is included before agreeing to a fee.
When is it worth paying an accountant?
Using an accountant can be worthwhile if you are unsure what to report, have more than one income source, are self-employed, own rental property, have capital gains, work under CIS, are a director, or want to reduce the risk of mistakes.
A good accountant does not just submit numbers. They help you understand your tax position and avoid unnecessary problems.
How to reduce your accounting cost
You can reduce the time and cost by keeping your records organised.
Before sending information to your accountant, prepare:
- income records
- bank statements
- receipts
- invoices
- rental statements
- dividend vouchers
- pension contribution records
- CIS statements
- mileage records
- previous tax return details
The cleaner your records, the easier the return is to prepare.
Warning signs of a poor Self Assessment service
Be careful if someone promises unrealistic tax refunds, suggests claiming personal expenses as business costs, refuses to explain the figures, does not check your records properly, or charges very low fees without reviewing your situation.
A tax return is your legal responsibility, even if someone else prepares it.
