The Indiana side of each payment
Indiana taxes the same 1099 profit at a flat 2.95%, so a second payment goes to the state each quarter, about $308 on the $50,000 example, against $1,371 of Indiana income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Indiana's schedule and voucher with its tax agency, several states do not match the federal calendar exactly.
