Status
Inferred: no provision found in the saved statute or guide
Primary source (statute, regulation or agency publication saved in full)
Federal backup withholding under IRC 3406 (24 percent on a missing or mismatched TIN) applies in Connecticut exactly as everywhere else; this page covers only what the state adds. The 50-state tables put Connecticut next to its neighbours, and the Connecticut 1099 filing page covers whether the state wants its own copy of the 1099.
Withholding on non-wage payments to nonresidents
What Connecticut does not require
State backup withholding
No state backup withholding: Conn. Gen. Stat. 12-705; CT nonpayroll withholding covers pensions/annuities (lump sums), gambling winnings, athlete and entertainer payments only
Basis: Inferred: no provision found in the saved statute or guide.
Pass-through entity withholding (out of scope)
Connecticut pass-through entity tax regime (elective PE tax) replaced nonresident owner withholding. Entity-level withholding on distributions to nonresident owners is a duty of the entity, not of a payer, and is not covered on this page.
From the source
“withholding agents are required to withhold Connecticut income tax at the source of payment at a rate of 6.99% percent of the gross payment to performers”
