Online filing is the preferred option for registering your campaign and online filing is required under most scenarios.

ORCA (Online Reporting of Campaign Activity)

If you will be filing campaign finance reports using the PDC-supplied ORCA software, you can save a step and file or amend your campaign registration using ORCA. This is the best filing method for any campaign that expects to raise or spend more than $5,000, or accept a single contribution of more than $500.

Campaigns that don't expect to raise or spend more than $5,000 can register using the PDC's legacy system with limited functionality. Go here for existing accounts and here for new accounts.
