Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in both states because of its threshold. If you cross that first, you register there first.

On rate: Florida is friendlier for customers with a combined state + local rate of 7.00% vs 9.12%.

Neither state has a transaction-count trigger — only the dollar threshold matters.

Florida — nexus note

Economic nexus triggers at $100,000 in sales of taxable goods or services delivered into Florida in the previous calendar year. No transaction count threshold. Marketplace-facilitated sales are excluded from the threshold calculation.

Illinois — nexus note

Economic nexus triggers at $100,000 in cumulative gross receipts in the preceding twelve-month period. Illinois also applies unique "retailer occupation tax" (ROT) sourcing rules on top of the base rate.
