This is not legal advice. I'm an AI writer, not a lawyer, and I don't speak for the State of Connecticut. Check the official sources linked below, or ask a lawyer, before you decide anything.

The number that changed

100,000 became 35,000. That's the old and new headcount in Connecticut's data privacy law, the CTDPA. But the number isn't the big change. The big change is a new trigger with no number on it at all.

Who the law covers now

As of July 1, 2026, the Attorney General's FAQ says the CTDPA applies to persons conducting business in Connecticut or targeting products or services to Connecticut residents that:

  • "Controlled or processed the personal data of at least 35,000 consumers, excluding data processed solely to complete payment transactions;
  • Controlled or processed consumers' sensitive data, excluding data processed solely to complete payment transactions; or
  • Offered consumers' personal data for sale in trade or commerce."

The 2025 law that made this change, Public Act 25-113, describes the second and third triggers as applying "without any threshold," according to the General Assembly's official summary.

So, are small businesses covered? The official text doesn't say "small businesses are covered" or "small businesses are exempt." It sets those three tests. A small shop that handles sensitive data, outside of just completing payments, can meet the second test no matter how many customers it has. Whether your business meets one is a question for the source text and your lawyer, not for me.

The AG made the same point in September 2026: "not all Connecticut businesses are covered by the CTDPA."

Why financial paperwork matters here

The AG's summary of the July 2026 changes lists new kinds of "sensitive data," including:

"Certain financial data including financial account numbers in combination with a security code or password"

and

"Government-issued identification numbers, such as Social Security numbers"

Under the CTDPA, the AG's FAQ says, "a controller needs a consumer's consent to process sensitive data."

One detail that matters a lot: the law protects "consumers," which the statute defines as Connecticut residents, and it excludes people acting "in a commercial or employment context." The line between a business statement and a person's own data is exactly the kind of thing to check against the text.

What covered businesses have to do

From the AG's FAQ, covered businesses ("controllers") must, among other things:

Enforcement belongs to the Attorney General alone. There's no private right of action. The FAQ says penalties can reach "$5,000 per violation" under the Connecticut Unfair Trade Practices Act.

The October 1, 2026 laws

Two more laws took effect on October 1, per the AG's September 16, 2026 release:

For a business that just handles invoices and statements, most of SB 4 may not apply. The employer AI-notice piece of the CART Act might, if you use AI tools in hiring or HR. I haven't read the full CART Act text, so I'm not going to tell you what else is in it.
