Many businesses are required to collect sales tax from their customers and send it to the government. When a customer buys a taxable item, the business adds sales tax to the price. The customer pays the total — the sale price plus the tax.
Here is the key concept: sales tax collected from customers is not business revenue. The business is acting as a middleman. It collects the tax on behalf of the government and holds it until it is time to remit. From the moment the tax is collected, it is a liabilitycalled Sales Tax Payable.
As we saw in Sales and Revenue, money received is not automatically revenue. Sales tax is a clear example of this principle.
Taxable vs. Nontaxable Sales
Not all sales are taxable. Whether a sale is taxable depends on what is being sold, where the customer is located, and whether the customer has a tax exemption. Sales tax rules vary by jurisdiction — this lesson teaches the bookkeeping mechanics, not jurisdiction-specific tax law.
- • Taxable sale: sales tax is added to the price. The tax is collected and recorded as a liability.
- • Nontaxable sale: no sales tax is added. The customer pays only the sale price. Revenue is recorded with no tax liability.
For a taxable sale, the customer pays more than the sale price. For a nontaxable sale, the customer pays exactly the sale price.

A customer purchases $1,000 of taxable goods. The sales tax rate is 8%.
| Item | Amount |
|---|---|
| Sale Price (Revenue) | $1,000 |
| Sales Tax (8%) | $80 |
| Customer Pays | $1,080 |
The journal entry when the sale is recorded:
| Account | Debit | Credit |
|---|---|---|
| Cash | 1,080 | — |
| Sales Revenue | — | 1,000 |
| Sales Tax Payable | — | 80 |
Later, when the business remits the $80 to the tax agency:
| Account | Debit | Credit |
|---|---|---|
| Sales Tax Payable | 80 | — |
| Cash | — | 80 |
Notice: no expense appears in the remittance entry. The tax was never revenue and never an expense. It was a liability from the start, and the payment simply clears it.
Reconciling Sales Tax
The Sales Tax Payable account should be reconciled regularly. The balance should equal the total tax collected but not yet remitted. If the balance does not match what the business owes, something was recorded incorrectly — perhaps a taxable sale was recorded without tax, or a nontaxable sale had tax added by mistake.
When a customer returns a taxable item, both the revenue and the sales tax must be reversed. The business no longer owes that tax to the agency, so Sales Tax Payable goes down.
Do It
Complete the sales tax worksheet below. Calculate the revenue, sales tax, and customer total for each sale. Then find the totals and the ending Sales Tax Payable.

Below are four sales transactions. The sales tax rate is 8%. For each sale, calculate and enter:
- Sales Revenue (the sale amount before tax)
- Sales Tax Collected (revenue × 8% if taxable; $0 if not)
- Customer Total (revenue + tax)
For the refund, use negative numbers — the sale is being reversed. Then calculate the totals, the ending Sales Tax Payable, and the balance after remitting the tax to the agency.
| Sale | Revenue (type) | Sales Tax (type) | Customer Total (type) |
|---|---|---|---|
| Taxable sale — consulting services Amount: $800 (taxable) | $ | $ | $ |
| Nontaxable sale — exempt client Amount: $600 (nontaxable) | $ | $ | $ |
| Taxable sale — product sale Amount: $1,200 (taxable) | $ | $ | $ |
| Customer refund — returned taxable item Amount: $200 (taxable) | $ | $ | $ |
| Total Revenue (type) | $ | Total Tax (type) → | $ |
Now complete the Sales Tax Payable section:
Ending Sales Tax Payable (total tax collected, starting from $0)
The business remits the full amount to the tax agency. What is the new Sales Tax Payable balance?
