What a Buyer's Advisor Will Find in Your Tax Records and How to Prepare

If you are planning to sell your business, take on outside investment, or bring in a private equity partner in the next two to five years, your tax records will definitely be reviewed. And in detail by advisors whose job is to identify issues.

What they find and how organized it is directly affects your price, your timeline, and in some cases whether the deal closes at all. I have seen this from first-hand experience. Timeline can get impacted since tax typically comes towards the end of the deal-making process.

Here is what they look at and how to make sure you are ready.

What Tax Due Diligence Actually Covers

A buyer's tax advisor will typically request the last three to five years of federal and state returns for every entity in your structure. They will review your filing history for consistency, look for open audit years, and ask for documentation supporting significant positions on your returns.

They will also review your multi-state registration history where you are registered, where you should be registered, and whether there are gaps. They will review if your entities have active and in good standing statuses where they do business. This is an often-overlooked detail. They will look at intercompany transactions between related entities and whether those are documented and at arm's length. And they will review your equity and ownership history for any transactions that created unreported tax obligations, notably distributions or owner loans.

The Three Things That Most Often Affect Price

In my experience, three categories of tax issues surface most often in due diligence and have the most direct impact on deal terms.

The first is multi-state nexus exposure. Businesses that have expanded without tracking their state tax obligations often discover during due diligence that they have years of unfiled returns and unregistered states. Buyers price this exposure into the offer or require escrow holdbacks to cover potential liabilities. This can be sales tax, payroll tax or a gross receipts type tax, or all three.

The second is undocumented positions. If your returns include depreciation elections, accounting method choices such as inventory, loss carryforwards, or missing basis calculations that are not supported by written documentation, a buyer's advisor will flag those positions as potential risk. The risk gets priced and not in your favor.

The third is entity structure messiness. Informal intercompany transactions, loans between entities with no documentation, and ownership changes that were never properly reported can all create trailing tax exposure that has to be addressed before closing.

How to Prepare

The goal is to have clean, organized, documented tax records before anyone asks for them. That means assembling the last three to five years of returns for every entity, with a clear summary of your state filing history, open tax years, and any positions that carry judgment or risk.

It means having written documentation for any significant tax position not because you are wrong, but because you need to be able to explain it clearly when asked.

And it means addressing any known exposure like unfiled state returns, unregistered states, informal intercompany balances proactively, through voluntary disclosure where appropriate, rather than having it surface in due diligence where you have no leverage and will hit the purchase price.

The Right Time to Start Is Not When You Have a Letter of Intent

By the time you are in active deal negotiations, you do not have time to build tax infrastructure from scratch. The window to prepare is two to three years before a transaction so long enough to address exposure, document positions, and have clean records to present.

Our Tax Infrastructure and Process Build-Out is designed exactly for this window. The due diligence readiness file is one of the deliverables, and for pre-transaction businesses, it is often the highest-priority starting point.

Start with the assessment. You will know exactly what a buyer's advisor would find today, and what it would take to be fully prepared.
