QUESTIONS TO ASK WHEN BUYING A BUSINESS ABOUT TAXES, CASH FLOW, AND FINANCIAL RISK

The seller tells you the business is profitable. The financial statements look clean. The customers seem loyal, the bank is willing to finance the deal, and everything on paper points toward a solid acquisition. So you move forward.

Then six months after closing, it starts to unravel. Payroll taxes surface that were never remitted to the IRS. Three of the top five customers quietly move their business elsewhere. Cash gets tight in ways you didn’t anticipate. Equipment that looked functional needs immediate replacement. And suddenly you’re dealing with liabilities that were never disclosed, never visible, and never part of your original calculations.

This is not a rare story. It happens to experienced buyers, well-funded buyers, buyers who had lawyers at the table. Because buying a business is not simply buying its revenue. You’re buying every decision that was made over the last decade, every shortcut taken, every obligation deferred. The asking price might be fair, but what you’re inheriting could shift that equation entirely.

That’s what acquisition due diligence is actually about. Not just confirming numbers, but asking the right questions to understand exactly what you’re stepping into before you’re legally bound to it. The questions below won’t kill a good deal. They’ll help you structure it better, negotiate smarter, and walk in with clear eyes.

Why Is The Owner Actually Selling?

Most buyers assume retirement. That’s often true. But the seller’s actual motivation is one of the most telling things you can uncover early, and it’s one of the most important questions to ask when buying a business.

There’s a real difference between someone selling because they’re ready to step away from a strong operation versus selling because the business has quietly been losing its largest customer for two years. Both sellers will say similar things early on. The difference shows up when you press further.

Healthy reasons to sell:

• Retirement or a lifestyle change
• Succession challenges with no obvious heir
• A desire to pursue a different opportunity

Red flags worth paying attention to:

• Declining profitability over the past two to three years
• Major customer losses not fully disclosed upfront
• Regulatory or compliance issues in the background
• Chronic cash flow problems masked by accounting adjustments

Ask directly: Why now? Have previous buyers walked away, and if so, why? And perhaps most useful of all: if you were the buyer here, what would concern you most? The hesitation or candor in that answer tells you a great deal.

Are The Financial Statements Actually Telling The Full Story?

Many acquisitions run into trouble because buyers trusted financial statements without understanding what they were actually reading. Reviewed statements and audited statements are not the same thing. Cash-basis and accrual accounting tell different stories. And owner-operated businesses frequently run personal expenses through the company in ways that distort normalized earnings significantly.

These are the due diligence questions to ask when buying a business that get to the heart of earnings quality:

• Who prepares the financial statements, and to what standard?
• Are the statements reviewed or audited by an outside CPA?
• Have accounting methods changed in the last few years?
• What owner-specific expenses are currently running through the business?

That last point matters more than most buyers realize. An owner might run a personal vehicle, family cell phone plan, travel, and health insurance through the business. Those expenses are legitimate for them but won’t continue after the sale. They also inflate reported expenses in ways that make profitability look lower than it actually is. These are called add-backs, and they need to be identified and normalized before any business valuation discussion means anything.

EBITDA adjustments and earnings normalization are exactly where a CPA-led review adds the most value early in the process.

How Strong Is The Business’s Cash Flow Really?

Profit and cash flow are not the same thing. A business can be genuinely profitable while constantly running short on cash. Revenue growth actually makes this worse, because growth consumes working capital. Understanding how a business actually generates and uses cash is one of the most important questions to ask when purchasing a business.

Start here:

• How much cash does the business generate annually?
• What are average collection periods on receivables?
• What percentage of receivables are more than 90 days old?
• Are there recurring periods where the business draws on a credit line just to make payroll?

Review These Three Reports Carefully

Income statements tell you about profitability. These three tell you about cash reality:

• Cash flow statement: Shows actual cash generated from operations, separate from accounting income.
• Accounts receivable aging: Reveals how collectible the revenue actually is. Old receivables are often uncollectible.
• Accounts payable aging: Shows whether the seller has been stretching vendors to make cash flow look better than it is.

If the income statement looks strong but these three reports look strained, you’re looking at a business with a cash flow problem hiding behind solid earnings numbers.

What Debt, Obligations, And Commitments Are You Inheriting?

Debt isn’t always obvious. Sellers don’t always volunteer the full picture, and part of what you’re doing in due diligence is building a complete liability map before you’re responsible for any of it. Ask specifically about:

• What bank loans currently exist, and what are the terms?
• Are there personal guarantees from the seller that need to be addressed at closing?
• Are there equipment leases or vendor disputes with outstanding balances?
• Are any balloon payments approaching in the next 12 to 24 months?

Beyond obvious debt, look at contract commitments, real estate lease obligations, software licensing agreements, and service contracts that survive the sale. Buyers regularly discover after closing that they’ve inherited a long-term lease on a space they don’t need or equipment financing on assets they didn’t know existed. These obligations reduce future profitability in ways that weren’t reflected in the purchase price.

Are There Any Tax Problems Waiting To Surface?

This is one area where having an experienced CPA involved in your due diligence is not optional. Tax exposure has a way of becoming the buyer’s problem very quickly after closing, even when the liabilities technically predate the transaction.

The IRS has long reach, and so do state tax authorities. Ask before signing:

• Are all federal and state tax returns filed and current?
• Are payroll taxes current, including deposits and quarterly filings?
• Has the business ever been audited, and were all issues fully resolved?
• Are sales tax filings current in every state where the business operates?
• Does the business have state income tax nexus it hasn’t been filing in?
• Have all employee classification decisions been documented and defensible?

Tax Areas Buyers Commonly Overlook

• Payroll taxes: Unpaid or misfiled payroll taxes carry personal liability that can transfer to new ownership depending on deal structure.
• Sales tax: Multi-state businesses frequently have obligations in states where they’ve never filed.
• Employment classification: Contractors who should have been employees create back payroll tax liability and potential claims.
• Property tax: Particularly relevant in oil and gas, agriculture, and real estate operations.

A CPA-led review specifically focused on tax exposure can surface these issues before they become your problem. Our Mergers and Acquisitions team works through exactly this process with buyers who want to close confidently.

How Dependent Is The Business On A Few Customers Or Employees?

A business can look very healthy while carrying enormous concentration risk. Revenue concentrated in two or three customers is fundamentally fragile. Human capital that lives entirely in the owner’s head is worth far less than it appears on the day you’re evaluating it.

Customer risk questions:

• What percentage of total revenue comes from the top five customers?
• Are there written contracts, or are these informal relationships?
• Are those customer relationships tied personally to the current owner?

Employee risk questions:

• Who would be hardest to replace if they left in the first year?
• Is institutional knowledge documented, or does it live with one or two people?
• Are there retention agreements for critical staff?

If the top salesperson walks at closing, or the lead technician who knows every system decides new ownership isn’t for them, the revenue projections you underwrote may not hold.

What Does Payroll Really Cost?

Payroll looks simple on the surface. The number on the payroll register is not the full cost of a workforce, and buyers who underestimate this create cash flow problems almost immediately after taking over.

Ask about:

• Are all employees properly classified under federal and state wage law?
• Are compensation structures changing, or are increases expected?
• What are the accrued paid time off liabilities, and will those transfer?
• Are there bonus expectations or informal compensation arrangements not reflected in payroll records?

The full cost of payroll includes payroll taxes, workers’ compensation insurance, benefits contributions, accrued PTO, and any retirement plan obligations. Using QBO or similar tools helps buyers trace actual labor costs across periods, but the software is only as accurate as the data that’s been entered. A manual verification of payroll records against bank statements is always worth the time.

What Hidden Liabilities Could Reduce Future Profitability?

Operational and legal risks rarely show up in a financial statement review. They surface later, usually at the worst possible time. This part of due diligence requires a different kind of attention, focused on what the business is exposed to that hasn’t been quantified yet.

Ask about:

• Are there any pending or threatened lawsuits?
• Have customers, vendors, or former employees made legal threats in the past three years?
• Are there warranty obligations that could generate future claims?
• Are there environmental compliance issues? This is especially relevant in oil and gas, agriculture, and manufacturing.
• Are there regulatory compliance concerns specific to the industry?

Industry-specific risks deserve real attention here. Oil and gas businesses may carry environmental remediation exposure. Real estate businesses may have deferred maintenance obligations or tenant disputes. Service businesses can carry professional liability exposure that doesn’t appear until after closing. If hidden liabilities surface after you’ve signed, you have limited recourse unless your purchase agreement specifically addresses them. The time to find them is before.

What Will The Business Look Like After The Current Owner Leaves?

This question gets underestimated more than any other. A business that runs smoothly because of the owner’s relationships and daily involvement is a very different business once that person is gone.

Ask directly:

• How involved are you in day-to-day operations today?
• Which customer relationships are personal to you?
• What percentage of revenue is directly tied to your presence?
• What is the transition plan, and how long are you willing to stay involved?

Warning signs of an owner-dependent business:

• The owner handles all significant sales conversations
• Major decisions require their personal approval
• Key customers deal exclusively with them and have no relationship with the team

Transition planning is often more important than valuation. A business worth $3 million on paper may be worth significantly less if the owner’s exit takes 40% of the revenue with it.

The Due Diligence Questions Smart Buyers Never Skip

Financial Questions:

• Are earnings sustainable, or inflated by one-time events?
• Is cash flow healthy enough to service acquisition debt and fund operations?
• Are receivables collectible?

Tax Questions:

• Are all federal and state filings current?
• Are there open IRS matters or audit risks?
• Are payroll taxes fully paid and documented?

Operational Questions:

• Are key employees staying post-acquisition?
• Is the customer base diversified enough to absorb a loss?
• Is institutional knowledge documented?

Legal Questions:

• Are all material liabilities disclosed?
• Are customer and vendor contracts transferable?
• Are there pending or threatened claims?

Good sellers expect these questions. Sellers who resist them are telling you something.

The Goal Isn’t Finding Reasons To Walk Away

Good due diligence doesn’t kill deals. It helps you close better ones. When you ask the right questions before signing, you’re positioned to negotiate fair terms, structure the transaction properly, and protect the future profitability you’re counting on.

Some buyers negotiate a price reduction after uncovering tax exposure. Others adjust escrow holdbacks to cover identified liabilities. Others find the risks are entirely manageable and close with confidence because they’ve done the work. All of those outcomes are better than discovering problems six months after the deal is done.

If you’re evaluating an acquisition and want a CPA partner with experience across oil and gas, real estate, private equity, and entrepreneurial businesses, we’d be glad to help.
