Tax Return Reconciliation in a QoE Report: Why Your Numbers Should Tie to the Returns

Most small business sellers have two sets of numbers. One is the profit and loss statement (P&L) they use to market the business. The other is the tax return they filed. They are supposed to describe the same company, but they often do not match. A tax return reconciliation is how a quality of earnings (QoE) review checks that the two tell the same story, and explains the differences when they do not.

Why the P&L and the tax return differ

Sellers have opposite incentives in two places. On a tax return, lower profit means lower taxes. On a P&L used to sell the business, higher profit means a higher price. Neither is necessarily dishonest, because tax rules and accounting rules are not the same. But the difference is exactly what a buyer needs to understand before agreeing on a price.

Which return to look at

Business structure	Typical return	Where to look
Sole proprietor or single member LLC	Schedule C with the owner's Form 1040	Gross receipts, expenses, and net profit on Schedule C
S corporation	Form 1120-S	Gross receipts, officer compensation, and the reconciliation schedules
Partnership or multi-owner LLC	Form 1065	Gross receipts, guaranteed payments, and the reconciliation schedules
C corporation	Form 1120	Gross receipts, officer compensation, and taxable income

How a tax return reconciliation works

1. Collect the filed returns for the same years as the financials. Usually two to three years. Ask whether they were actually filed and whether any were amended.
2. Start with revenue. Compare gross receipts on the return to revenue on the P&L for each year. This is the cleanest test, because revenue should be close.
3. Move down to profit. Compare net income on the return to net income on the P&L.
4. List every difference and give it a reason. Depreciation, personal expenses, timing, one time items, and the accounting method are the usual causes.
5. Chase down what is left. Whatever cannot be explained by a normal reconciling item is where the questions begin.

Differences that are usually normal

Item	Why returns and books differ	What to ask
Depreciation	Tax rules often allow faster write offs of equipment than the books show.	Was there a large equipment purchase? Does the asset list match what exists?
Cash vs. accrual	The return may be on one method and the books on another.	Which method does each use, and has it changed?
Personal expenses	Some are deducted on the return and added back on the P&L as owner perks.	Is there support for each add-back?
Non deductible items	Some expenses on the books are limited or disallowed for tax purposes.	What are they, and do they recur?
One time items	A legal settlement or asset sale may hit one year only.	Is it truly non recurring?

Differences that deserve a hard look

• Revenue on the P&L is higher than on the return. The seller may be showing the buyer revenue that was never reported to the government, or the P&L may be inflated. Both are problems.
• Profit on the return is far below profit on the P&L. A few add-backs are normal. A large pile of them is a sign the numbers are being stretched.
• The seller will not share returns. If a seller will show you a P&L but not the filed returns, that is information in itself. Our guide on what to do when a seller won't provide documents covers your options.
• Unsigned drafts, extensions, or missing years. Ask for the filed version, and ask why any year is missing.
• Years that do not match the story. If the listing says the business earns $400,000 and three years of returns show $120,000, the gap needs a clear explanation, not a shrug.

Why lenders care

Lenders generally underwrite small business loans off filed tax returns, and they want to see that the numbers in the deal match them. Income that was never reported is hard to verify and hard to finance. That is a big reason why a clean reconciliation makes underwriting smoother.

How it fits with a proof of cash

The two tests check different things. A proof of cash tests whether the money in the bank matches the revenue on the books. A tax return reconciliation tests whether the books match what was reported to the government. When the books, the bank, and the return all line up, you can have much more confidence in the earnings you are pricing. When one of the three does not, you have found the place to dig.

Common questions

Why does the seller's profit differ between the P&L and the tax return?

Usually because of depreciation, owner perks, timing, and accounting method. Those are normal and explainable. A difference that cannot be tied to specific items is the one to worry about.

Can I pay for income the seller never reported?

It is risky. Unreported income is hard to verify, lenders generally will not finance on it, and it can create legal and tax exposure. Talk to your attorney and tax advisor before pricing any part of a deal on income that is not on the returns.

How many years of returns do I need?

Usually the same two to three years as the financial statements being analyzed, plus current year to date numbers from the books. More years help show whether the business is growing, flat, or declining.

Is a tax return reconciliation the same as a tax review?

No. It compares the numbers on the returns to the numbers in the books. It does not review whether the returns were prepared correctly or whether the seller owes any taxes. Ask your tax advisor about that separately.
