Co-op Flip Tax Calculator
Most NYC co-ops charge a flip tax on resale, set by the building’s proprietary lease — but not all buildings calculate it the same way. This calculator supports the three real methods buildings actually use: a percentage of the sale price (most common), a percentage of your profit, or a flat amount per share.

Glossary
A transfer fee some co-op buildings (and occasionally condos) charge on resale, paid to the building rather than to any government — the money goes into the building’s reserve fund. It’s set by the proprietary lease or house rules, not by law, so it varies entirely by building. Many buildings charge none at all. Read our full guide to NYC flip tax.
Over 80% of NYC co-op flip taxes are a straight percentage of the sale price, typically 1-3%. The rest are usually either a percentage of your profit (sale price minus your cost basis) or a flat dollar amount per share owned. Check your proprietary lease or ask your managing agent which method your building uses.
The seller pays the flip tax in the large majority of NYC buildings, though a small number of proprietary leases assign it to the buyer instead — another detail worth confirming before you’re under contract.
