Does this calculate my final federal tax?

No. It estimates potential recognised versus deferred gain, not a final tax return.

Cash or non-like-kind property received in the exchange; it can make part of the gain taxable.

Do I need a qualified intermediary?

Most deferred exchanges use a qualified intermediary. Obtain legal and tax advice before closing.

Where do the rates and rules come from?

The calculator links its source in the methodology section. Confirm figures using the official source and a local adviser before signing.
