Illinois 1099-K rules for 2026: $1,000 and four transactions
Illinois sets a 1099-K floor of $1,000 and four transactions — far below the federal $20,000 and 200-transaction test. If you take cards or app payments, this is the rule that will actually reach you.
Four card jobs and $1,000 is a low bar.
A lawn or junk-removal operator running Square through a season clears it easily, while never coming close to the federal test.
Card-processor 1099-K has no federal dollar floor at all.
The $20,000 / 200 test applies to third-party settlement organizations. Payment-card transactions are reported without a dollar threshold.
1099-K and 1099-NEC are different forms with different rules.
You can get a 1099-K from Square and no 1099-NEC from the same customer, because the $2,000 floor is a separate test.
Watch for double-counting.
If a client pays you by card, that income can appear on a 1099-K. Do not also add a 1099-NEC amount for the same dollars when reconciling.
