How to Figure Sales Tax If You Have a Coupon in Missouri

By Business & Finance Last updated Friday, June/14/2024

1). Take the total sum of the purchase and subtract the coupon value from the total. For example if the sum is $101 and the coupon total is worth $1 off the price, your new final total after coupons is $100.
2). Multiply the final total by .04225, which is the decimal form of the Missouri sales tax rate of 4.225 percent. For example, if the final total is $100, multiplying it by .04225 gives you 4.22 --- you pay about $4.23 in sales tax.
3). To figure the final cost, add the final total to the amount of sales tax you're paying. For example, if the total bill is $100 and the tax you're paying is $4.225, then the total amount you owe is $104.23. Always round to the nearest hundredth of a decimal.
