How do you review prior business tax returns and accounting records together to find missed tax savings?

We take the general ledger and supporting records a return was built from, alongside the return, and compare what the records said against what the rules required. Most missed savings are classification decisions in the books rather than errors on the form, which is why a return-only second opinion does not find them.

Prior-year business tax return review

Q: Can a review find taxes overpaid because expenses were categorized incorrectly?

That is the most common case. A misclassification between capitalization and expense, applied consistently over several years, produces a return that is internally correct and still wrong — and it is invisible to anyone checking only the return.

The question

Did a prepared return miss something legitimate?

Usually the return did not miss it. The books did, and the return was accurate about inaccurate records.

Returns are prepared from the accounting a client provides. A preparer working from a trial balance is answering the question "does this return correctly report these records?" — not "were these records right?" Both are legitimate scopes of work. Only one of them finds a capitalisation decision that should have been an expense, repeated across four years, sitting in a fixed-asset schedule nobody had reason to revisit.

So a review that is going to find anything has to start one layer down, in the ledger, and work up to the return.

The sequence

Three questions, in this order.

One

Is the treatment actually wrong?

Not "is there a more favourable treatment available" — that is a different and later question. Was the position taken supportable under the rules as they stood in that year, on the facts as they were? A finding that cannot answer this cleanly is not a correction, and we do not present it as one.

Two

Is there a mechanism to fix it?

Being wrong is not sufficient. There has to be a route. An amended return, a Form 3115 change in accounting method with a §481(a) adjustment, or no mechanism at all. These are not interchangeable — they have different filing requirements, different timing, and different consequences for the years around them.

Three

Is the year still open?

The refund window depends on when the return was filed and when the tax was paid. If we do not have those dates, we do not know, and "we cannot determine this" is the answer we give — not an assumption that the year is open, which is the assumption that wastes a client's money on work that cannot produce a refund.

Limits on this page specifically

What a review of this kind cannot do.

It cannot tell you what you will recover before it runs. Anyone quoting you a figure in advance is quoting an average, and averages across other people's businesses say nothing about yours.
It cannot reopen a closed year. Where the window has passed, the finding is still worth having — it usually means the same treatment is still running forward and can be corrected going ahead — but it is not a refund.
It cannot replace the judgment of the professional who signs. Findings arrive with reasoning and authority attached so that a CPA can evaluate them quickly. Evaluating them is still the job.

How do you know whether a business should amend a prior-year return?

Three questions in order: is the item wrong, is there a mechanism to correct it, and is the year still open. The mechanism is an amended return, a Form 3115 change in accounting method, or nothing. Where the dates needed to evaluate the refund window are unknown, we report that it cannot be determined.
