Why might amounts in TaxJar not always exactly match my sales tax return?

Sellers sometimes run into a small discrepancy between the amount of sales tax you actually collected from the state and the amount of sales tax that the state wants you to report and pay. The reason why? Rounding.

Many, though not all, states require that you round the amount of sales tax you collected, at least in part. 

Let's use a very simplified example:

Say you sell three items in the same state and local area, and all cost $18.76. The tax rate is 1%.

In this case, since 76 is greater than 50, you'd round up at the item level when you charge sales tax, so you'd charge your customer .19 in sales tax on all three items, for a total sales tax of 57 cents. (.19 x 3 = .57).

However, when you file your sales tax return, you are asked to total these three sales.

$18.76 x 3 = $56.28. 

Because 28 is less than 50, you'd be required to round down here. 10% of 56.28 rounded down is just .56.

In just 3 sales, we already see a discrepancy of .01 between what you collected and what the state expects to see.

Imagine when you do a high volume of sales. The amount of sales tax you actually collected, and the amount of sales tax the state expects to see, can vary quite a bit.

In TaxJar, your "Expected Sales Tax Due" report takes these rounding discrepancies into account. That is one reason why you may sometimes also see a small difference between your "Actual Sales Tax Collected" and "Expected Sales Tax Due" report in TaxJar.
