You may already have an accountant who understands your business and handles annual accounts, payroll, bookkeeping or routine tax compliance. A separate specialist tax engagement can be used for a particular transaction, investigation or technical issue without moving the rest of that work.
These are typical situations where an otherwise satisfactory accountant-client relationship can continue while separate specialist tax work is undertaken.
Specialist review and representation can be scoped separately from the accountant preparing the annual accounts or returns.
HMRC support → Cross-borderResidence, foreign income, overseas workdays and treaty issues may require work beyond routine UK compliance.
International tax → PropertyOwnership changes and incorporation can require transaction-specific tax analysis before legal steps are taken.
Portfolio structuring → Business transactionThe tax implications of a sale, reorganisation or ownership change are better reviewed before the transaction becomes fixed.
Sales & restructuring → Employment equityEquity awards can require specialist analysis where payroll, disposals or international work patterns interact.
Employee shares → Technical adviceA defined written tax review can be commissioned for one question without transferring the client's wider accounting relationship.
Specialist tax advice →The most efficient arrangement is usually one where everybody knows which adviser owns which part of the work. That avoids duplicated requests, inconsistent assumptions and uncertainty over who is responsible for filing or implementation.
With the client's authority, relevant information can be exchanged with the existing accountant where doing so is necessary for the specialist engagement.
Identify the transaction, investigation or technical issue that needs separate input.
Determine which records are needed and whether the client wants us to liaise directly with the existing accountant.
Prepare the agreed calculation, advice, disclosure or representation without duplicating unrelated routine work.
Establish whether we, the existing accountant or another professional will carry out the resulting filing or transaction steps.
The exact split varies by client, but the model below illustrates how responsibilities can remain clear.
A specialist engagement does not need to disrupt an existing professional relationship where the scope and communication are handled properly.
No. A specialist engagement can be restricted to the matter concerned while your existing accountant continues the routine work they already undertake.
Yes, where you authorise the information sharing and direct communication is useful for the engagement. Only information relevant to the agreed work should need to be exchanged.
That should be agreed in advance. The specialist engagement may include implementation, or the advice may be passed back to the existing accountant for incorporation into the relevant return or accounts.
Material differences should be identified and discussed rather than hidden. The relevant facts, legislation, evidence and assumptions can then be compared so the client understands the basis of each view.
The engagement remains limited to the scope agreed with you unless you later instruct us separately for additional services.
Confidentiality, authority to exchange information and responsibility for implementation should all be clear where more than one adviser is involved.
