What is a tax return review?

A tax return review is a CPA's line-by-line examination of a return you prepared yourself (using software) or had prepared by another preparer. We check for errors, missed deductions, incorrect filings, and opportunities for savings. If we find issues, we explain them and can prepare an amended return to recover any refund you are owed. If the return is correct, you gain confidence that nothing was missed.

Should I get a second opinion on my tax return?

If your return was prepared by tax software, a franchise chain, or a preparer who spent minimal time understanding your situation, a second opinion is valuable. Software asks questions but cannot interpret your unique circumstances. A CPA review often finds deductions, credits, or strategies that software and seasonal preparers miss, especially for business owners, investors, and multi-state filers.

What happens if you find errors in my return?

We explain exactly what was wrong, how it affected your tax liability, and what the correction would look like. If an amendment would result in a refund, we can prepare and file it. If the error would increase your tax, we advise on the best path forward, which may include voluntary correction to minimize penalties. You decide whether to proceed, there is no obligation.

How much does a tax return review cost?

The cost depends on the complexity of the return, individual returns are less expensive to review than business returns with K-1s and multiple entities. We provide a quote after a brief consultation. Many clients find that the savings identified during the review far exceed the cost, and the review fee is often credited toward amendment preparation if one is needed.

Can you review multiple years of returns?

Yes. We frequently review two to three years of prior returns, especially for clients who have been using the same software or preparer for years. Multi-year reviews can uncover patterns of missed deductions and, if amendments are warranted, we can file them for each applicable year within the three-year statute of limitations.

The Value of a Second Opinion

Tax software processes what you enter. It does not ask whether you should be an S corp, whether you are capturing all your vehicle deductions, or whether your retirement contributions are structured optimally. It does not review your bookkeeping to ensure every expense is categorized correctly before it hits your return.

David Korzeniowski, CPA brings the expertise to spot what software and seasonal preparers miss. A review is low-risk, if your return is correct, you gain peace of mind. If errors are found, you have the option to amend and recover what you are owed. Either way, you know where you stand.
