Applicable Sales Tax Date

Here is the situation:

• On December 25,2024, I ordered online a computer (Order Date)
• The date on the invoice is December 26, 2024 (Invoice Date)
• On my online credit card account, the amount appeared as a posted transaction on December 31, 2024 (Posted Date)
• The monthly credit card statement will be available to me on January 17, 2025 (Monthly Statement Date)
• The amount for the monthly credit card statement is automatically deducted from my bank account on February 9, 2025 (Credit Card Payment Date).

Here is the question:

• Which date (Order Date, Invoice Date, Posted Date, Monthly Statement Date, or Credit Card Payment Date) determines to which tax year the appropriate sales tax belongs?
