Advance pricing agreement
An advance pricing agreement (APA) is an ahead-of-time agreement between a taxpayer and a tax authority on an appropriate transfer pricing methodology (TPM) for a set of transactions at issue over a fixed period of time (called "Covered Transactions"). Most APAs involve U.S. taxpayers and the US Internal Revenue Service (IRS), but APAs are also made outside the United States.
