The checkout moment matters.
For online orders, the safest approach is to place and complete the order during the state holiday window. A cart built before the weekend may not matter if the final checkout happens outside the window. A retailer may also update tax treatment only after shipping details are entered.
- Enter the shipping address before judging the tax line.
- Review the tax line after promo codes and substitutions.
- Avoid waiting until the final hour if a retailer has delayed order processing.
