Connecticut Campaign Contribution Limits, Explained

There isn’t one Connecticut contribution limit — there are a few sets of rules, and which applies depends on whether you’re a party (town) committee or a candidate committee, and whether that candidate participates in public financing. Getting the category right is the first step; the specific dollar amounts follow from it.

Party committees — including Democratic and Republican town committees — track each donor’s giving against a per-donor, per-calendar-year limit (on the order of $2,000 per individual per year; confirm the current figure on seec.ct.gov). The clock resets each January 1, and it’s the donor’s cumulative total across the year that counts — not any single gift.

Candidate committees work differently. Limits are set by the office being sought, and they apply separately to the primary and the general election. A donor can give up to the limit for the primary and, separately, up to the limit again for the general — so you have to attribute each contribution to the correct phase and track donors against the right bucket. This is covered in more depth in the Form 30 guide.

Regardless of committee type, there’s a separate limit on cash: a single cash contribution is capped at $100 (per CGS § 9-611). Anything above that has to come by check or another traceable method. It’s an easy rule to miss when someone hands you $200 at an event — split it, decline the excess, or take it another way.

If a candidate committee participates in Connecticut’s Citizens’ Election Program (CEP), the public-financing program, the limit framework changes entirely:

• Contributions are capped at a per-cycle limit instead of the standard office limits.
• Money from other committees, PACs, and state contractors is generally off-limits.
• You must raise a set amount in qualifying small contributions to receive a grant.

Participation is a per-cycle choice, and it governs which rules you follow all the way through.

Don’t confuse the two numbers treasurers deal with. The contribution limit is the most a donor may give; the $50 itemization threshold is the point at which you must report a donor’s full details (name, address, employer, occupation) on your filing. A donor can be well under the limit but still need full itemization once they cross $50.

The hard part is tracking each donor’s running total — especially when the same person gives several times, or gives under slightly different names. CT Committee Treasurer Suite groups a donor’s contributions (even across duplicate records), applies the right limit rule for your committee type and phase, and warns you the moment a contribution would put someone over — before you accept it or file. See the quickstart guide to get set up.
