The PET Advantage

Domestic CT LLCs can easily elect the PET. For higher-income members, this effectively makes CT taxes fully deductible federally — a benefit that often outweighs the apparent savings of forming in a "no-tax" state.

FAQ

Should I form in Delaware or Connecticut?

If you live and work in Connecticut: form in Connecticut. You'll owe CT taxes regardless of where you form. Adding Delaware just adds $300/year + complexity. Connecticut's PET makes its "high" taxes effectively cheaper than they appear.
