Contribution limits in special elections
A special election is considered a separate election with a separate contribution limit. In fact, a special election may itself involve separate special primary, special general and/or special runoff elections, each with a separate contribution limit.
When reporting contributions made in connection with a special election, be sure to check the appropriate box for type of election, and indicate that it is a special election (e.g., "2019 special primary," "2019 special general" or "2019 special runoff," as appropriate, such as in the case of the special elections in North Carolina).
