Start with the decision
How might an asset sale and a stock sale change what the owner keeps?
A buyer can offer the same headline price through an asset purchase or stock purchase and leave the seller with very different cash. This calculator separates owner stock basis, company asset basis, ordinary-income gain, capital gain, sale costs, debt, and a possible C-corporation second tax layer so the structure is discussed before terms become binding.

01
How to read it
Compare cash to the seller rather than comparing tax rates alone.
Ask for the proposed price allocation before signing a letter of intent.
Run the entity type, state, recapture, debt, and stock-basis facts through the CPA and transaction attorney.
02
What could change the answer
A negotiated purchase-price allocation or completed Form 8594
Earnouts, installment sales, rollover equity, working capital, escrow, or indemnities
Every depreciation-recapture, inventory, goodwill, real-estate, or state sourcing rule
Buyer benefits, legal liability transfer, purchase agreement terms, or a valuation
03
What to take forward
Use the result to identify which assumption needs verification, then bring that question to the professional helping you make the decision.

How the estimate works
See how the estimate is calculated
For the stock case, subtract sale costs and owner stock basis from price, apply the entered owner gain rates, and subtract debt and tax from closing cash.
For a pass-through asset case, measure gain above company asset basis and divide it between entered ordinary-income gain and remaining long-term gain.
For a C-corporation asset case, apply the entered company tax rate, calculate cash distributed after company tax and debt, and estimate shareholder tax above stock basis.
Common questions
Frequently asked questions
Why may sellers prefer a stock sale?
A stock sale may produce more long-term capital gain and avoid entity-level asset tax, but liability, buyer basis, contract transfer, and market leverage also matter.
Why may buyers prefer an asset sale?
A buyer may choose assets and receive new tax basis for future deductions while avoiding unwanted liabilities, subject to the agreement and tax rules.
What is Form 8594?
Buyer and seller generally use Form 8594 to report the agreed allocation among asset classes in an applicable asset acquisition.
Why is a C-corporation asset sale different?
Gain may be taxed at the corporation and remaining cash may be taxed again when distributed or liquidated to shareholders.
