Error Prevention Review (Self-Employed Returns)

What the review covers

A practical, compliance-focused review of your Self Assessment return and the evidence behind it, to help you submit accurate figures.

• Sense-checking income and expense totals against your records.
• Reviewing expense categories for common disallowable or misclassified items.
• Checking treatment of capital items and one-off purchases.
• Reviewing claims and reliefs (where relevant) for completeness and consistency.
• Identifying missing information, duplicates, or timing issues (wrong tax year).
• Flagging areas that may need clearer records if HMRC ever asks.

Who this is for

This service is designed for sole traders, freelancers and contractors who prepare their own figures or bookkeeping but want a professional safety check before filing. It is especially useful if you have had a busy year, mixed business and personal spending, multiple income streams, or you are filing self-employed pages for the first time.

How the review works

You share your draft return figures and the supporting records (for example, bookkeeping reports, bank statements, invoices, mileage logs, and expense evidence). We review for errors, inconsistencies, and missing items, then come back with a clear list of queries and recommended corrections. You stay in control of the final submission, with clarity on what to change and why.

What you get afterwards

You receive a concise summary of findings, the adjustments we recommend, and any record-keeping improvements that will reduce future risk. If anything needs deeper work, you will also get a clear next step, such as tidy-up bookkeeping, expense policy guidance, or a fuller tax review.
