Let’s say you own a coffee shop in Portland and sell a coffee maker for $200. You need to determine how much sales tax to charge.
Formula:
Sales Tax = Price × Sales Tax Rate
Calculation:
Sales Tax = 200 × 0.055
200 × 0.055 = 11.00
So, you need to charge $11.00 in sales tax.
Total Amount the Customer Pays:
Total Price = Price + Sales Tax
200 + 11.00 = 211.00
Your customer will pay $211.00 in total, and you will remit the $11.00 in sales tax to the Maine Revenue Services.
