Does the mansion tax apply to co-ops?

Yes. The New York State additional real estate transfer tax applies to qualifying residential cooperative interests as well as other covered residential property. Co-op shares are also subject to NYC RPTT; they are not exempt merely because the transaction transfers cooperative stock. Use the current verified tax schedules for the actual consideration and have the closing attorney confirm the calculation.
