To amend the Federal Election Campaign Act of 1971 to require all political committees to notify the Federal Election Commission within 48 hours of receiving cumulative contributions of $1,000 or more from any contributor during a calendar year, and for other purposes.

Real Time Transparency Act of 2017 This bill amends the Federal Election Campaign Act of 1971 to revise the notification requirement for campaign contributions of $1,000 or more. The bill applies this requirement to any political committee, not just a candidate's principal campaign committee, regarding cumulative contributions (instead of single contributions) of $1,000 or more during a calendar year. Only the Federal Election Commission (FEC) must be notified, instead of the FEC and others. Any amount transferred by a joint fundraising committee established by a candidate's authorized committee to any other authorized committee of that candidate shall be treated as a contribution. Senate candidates must file designations, statements, and reports directly with the FEC instead of via the Senate.
