Presidential Tax Transparency Act of 2019 This bill requires the President, the Vice President, and certain candidates for President and Vice President to disclose federal income tax returns for the ten most recent taxable years. The returns must be disclosed to the Federal Election Commission (FEC), which must make the returns publicly available after redacting information that is necessary for protecting against identity theft, such as Social Security numbers. If the tax returns are not disclosed to the FEC as required by this bill, the Internal Revenue Service must provide the returns to the FEC upon receiving a written request from the FEC.
