Is Sales Tax Calculated Before or After Discounts, Coupons, and Gift Cards?

Sales tax is calculated on the sale price, but what if discounts or coupons apply? While some situations have different tax rules, such as gift cards, BOGO deals, or manufacturer-reimbursed coupons, sales tax is generally calculated after discounts.

Sales tax compliance can feel complicated even in straightforward situations, with different rates applied to different products and companies often responsible for collecting sales tax in multiple states. But things become even more complex when selling items at a discounted price.

When a company offers discounts or promotions, such as buy-one-get-one deals, rebates, or coupons, both the seller and the buyer often face confusion about whether sales tax applies to the pre-discount sticker price or the reduced amount. 

In these situations, the general rule is that sales tax applies to the price the customer paid, so it's calculated after discounts and coupons are applied, not before. However, there are exceptions, including when sellers are reimbursed for discounts on purchases.

This guide explains the general rule for how discounts, rebates, coupons, and promotions affect sales tax, as well as how to make sure your store settings are correct so you're collecting the right amount of tax due on every sale.

The general rule: sales tax applies after most discounts

While there are some variations, most states follow the same general rule for sales tax on discounted products. As the Georgia Department of Revenue states: 

"The term ‘sales price’ applies to the measure subject to sales tax and means the total amount of consideration…whether received in money or otherwise. The ‘sales price’ does not include…discounts, including cash, term, or coupons that are not reimbursed by a third party that are allowed by a seller and taken by a purchaser on a sale."

This Georgia sales tax guidance is similar to how many states treat sales tax when discounts apply. It makes clear that:

  • Sales tax is applied as a percentage of the gross receipts. 
  • It is charged on the price the buyer paid after seller-funded discounts.

However, if the seller is reimbursed for the discount, then the reimbursed amount is included in the sale price, and sales tax is charged on the full amount. 

So, if a seller offers 20% off a $100 item and is not reimbursed for the 20% savings, sales tax is generally charged on $80. However, if a buyer has a $20 manufacturer's coupon, and the seller will be reimbursed the $20 by the manufacturer, then sales tax is charged on the full $100. 

Percentage discounts vs. dollar discounts

There is no difference in how percentage-based versus dollar-based discounts are taxed. Both are treated the same way for sales tax purposes. 

The table below provides some examples of how tax would work for both discount types.

Discount type Original price Discount Taxable amount
15% off phone accessory $60.00 $9.00 $51.00
$12 off phone accessory $40.00 $12.00 $28.00

Sales tax on gift cards: purchase vs. redemption

Gift cards are another source of confusion for buyers and sellers. As a general rule, most states charge sales tax on tangible goods and some services. Gift cards are neither. A gift card is a prepaid payment instrument, or stored value card, so no tax is charged at the time of its sale.

Again, there are slight variations in state rules, but this North Carolina law (17 N.C. Admin. Code 07B.3804) is representative of how states treat gift card revenue. The law states:

"Charges for gift certificates or gift cards are not subject to sales and use tax...at the time of initial sale for the gift certificate or gift card. When the holder of a gift certificate or gift card redeems the gift certificate or gift card for items…the transaction is subject to the same sales and use taxes applicable to the item as if it were purchased without a gift certificate or gift card."

California is another example, with the guidance stating, "Gift certificate transactions are not treated as discount transactions but regarded as credit memorandums."

If gift cards were taxable at the time of sale, tax pyramiding could occur. The buyer would pay tax on the gift card purchase but be taxed again when redeeming it. Instead, the tax is charged only at redemption, based on the value of the taxable goods sold. 

Because a gift card is not a discount, but a method of payment, there's also no reduction on sales tax when items are paid for with a gift card. If a customer purchases a $100 item with a $75 gift card, sales tax applies to the full $100 taxable selling price. 

Digital gift cards and gift cards issued as store credit are typically treated the same as stored payment methods, with the ordinary tax charged when the gift card or credit is used for payment. However, promotional credits require a deeper analysis. 

Sales tax treatment for gift cards issued as part of a promotion or reward

Things become more complex when gift cards are provided as part of a promotion or as a reward. These may be treated differently, with tax sometimes charged on the discounted value rather than the full price if the gift card is treated as a coupon or promotion. For example:

  • A promotional reward, such as $10 in Store Cash, may be treated as a discount rather than a gift card, depending on factors such as whether the Store Cash can be redeemed for cash or is transferable. 
  • A gift card offered through a bonus, such as buy $100 in gift cards, get $20 free, could result in the $20 being treated as a promotional discount or as cash, depending on factors like whether the promotional $20 could be redeemed independently of the original purchase, is transferable, can be combined with other promotions, or is subject to minimum purchase requirements. 
  • A product-specific voucher, such as "1 Free Coffee," may be treated as a promotional discount with no sales tax charged on the coffee.  

It is important to review state-specific guidance in these situations. For example, California uses this test to determine whether a gift card is a credit memorandum, rather than a discount. 

"In determining whether an instrument is a gift certificate, if the retailer refunds the customer cash or credit when the customer uses the instrument to purchase merchandise of lesser value than the instrument's assigned value, this is a clear indication that the retailer and the customer consider the instrument to be some form of credit memorandum…not a rebate or a cash or trade discount."

Store coupons vs. manufacturer coupons

The tax treatment of transactions involving coupons can also be complex because, in most states, the key question is whether the coupon is a manufacturer coupon or a store coupon.  

When a store coupon is used, the seller does not receive the full purchase price. As a result, sales tax is generally charged on the discounted price after the coupon is applied. 

However, when the manufacturer coupon is used, the seller is reimbursed by the manufacturer, so it does receive the full price of the item. Sales tax is generally charged on the full pre-coupon price.

Multiple state statutes explain these rules, including the following:

  • California Regulation 1670 states: "If a retailer distributes coupons to the public…without charge, tax does not apply to the discount allowed upon redemption of the retailer's own coupon. On the other hand, where the retailer redeems coupons issued by the manufacturer or by another third party, the measure of tax includes the amount collected from the customer as well as the amount collected by the retailer from the manufacturer or other third party." 
  • And Rhode Island's regulatory guidance says: "When a retailer issues a store coupon and receives no reimbursement for the value of the coupon from any third party, the tax is computed on the discounted sales price… When a retailer accepts a manufacturer's coupon for which it receives reimbursement from any third party, the sales tax is computed on the full selling price of the item…The reimbursement may be in any form, including cash or credit towards the purchase of additional merchandise."

However, while most states establish different sales tax rules based on whether a coupon is from a manufacturer or from the seller, not all do. In Texas, for example, the value of the coupon is typically excludable from the tax no matter who provided it. 

This rule is established by 34 Tex. Admin. Code § 3.301, which states:

"When coupons or certificates are accepted by retailers as a part of the selling price of any taxable item, the value of the coupon or certificate is excludable from the tax as a cash discount, regardless of whether the retailer is reimbursed for the amount represented by the coupons or certificate."

Other states that always charge tax on the post-coupon price include:

  • Pennsylvania, which typically charges tax on the post-coupon price provided that the coupon is properly reflected on the invoice or receipt
  • Massachusetts, which states that "If a vendor offers customers, upon presentation of a manufacturer's or retailer's coupon, a discount from the usual price of merchandise, the amount of such a discount is excluded from the sales price of tangible personal property upon which the sales tax is based, regardless of whether the retail vendor receives any reimbursement from the manufacturer, supplier or distributor." 

However, these states are in the clear minority, and, as the table below shows, the key factor determining whether tax is applied to the pre- or post-coupon price is whether the seller is reimbursed for the value of the coupon.

Coupon type Who funds the discount Taxable amount
Store coupon Retailer Discounted price
Manufacturer coupon Manufacturer/third party Full price (most states)

Sales tax on promotions: BOGO, two-for-one, and bundle deals

Bundled discounts and promotions, such as "buy one, get one free" or "two for the price of one," can be especially complex for sales tax compliance because the same economic result can be described in different ways, each with its own tax implications.

The key question in these situations is whether a seller was compensated for a "free" item or whether it was truly given away for free. 

  • If the seller was compensated, the buyer should owe sales tax based on the actual sales price. 
  • If the seller gave the item away, the seller may owe use tax because they purchased the item tax-free for resale and then used it for promotional purposes rather than reselling it. 

This is why the language matters so much when running promotions.

Buy one, get one free deals

If a retailer funds a BOGO promotion, sales tax commonly works in one of two ways:

  • The "free" item may be treated as a discount rather than a separate taxable sale. In this case, if a $50 shirt is BOGO, sales tax is charged on $50 because the seller is treated as having discounted the second shirt. Texas applies this rule, with official guidance stating: "A retailer advertises pants as 'buy one, get one free.' The first pair of pants is priced at $120; the second pair of pants is free. Tax is due on $120."
  • The "free" item may be treated as a promotional item, which would make the seller responsible for sales and use tax because the seller consumed the item. Massachusetts applies this rule, stating: "Generally, where property is transferred from a vendor to a customer for no additional consideration, or for a nominal consideration, or for an amount substantially below cost, the property constitutes a promotional item for sales tax purposes, and the vendor is considered its consumer. In this situation, the vendor must pay a sales or use tax based upon the amount the vendor paid for the item."

Two for the price of one and percent-off bundles

If the same deal is offered with different language, such as a two-for-the-price-of-one promotion, or a promotion for 50% off two items, then the retailer isn't giving away a free item. The seller is paid for both items, but at a discounted rate. So, sales tax is charged on the discounted price.

N.J. Admin. Code § 18:24-36.2(e) is an example of how this is often handled. Under this regulation, when a seller allows a buyer to purchase two items for the price of one and is not reimbursed by a third party, sales tax is calculated on the reduced price paid for both items.

Sales tax on rebates

Finally, it is important to understand how sales tax on rebates works: 

  • If the retailer collects the full price at checkout and the buyer later obtains a rebate from the manufacturer, tax is charged on the full price of the item before rebates. That's because the seller collected the full selling price from the customer at checkout, and the customer's redemption of the rebate does not change the taxable sales price.
  • If an instant rebate applies and the price is reduced immediately, the transaction is generally treated the same way as when a coupon is applied. In many states, that means if the seller offers the rebate, tax is charged on the after-rebate price, but if the manufacturer offers the rebate and pays the seller back, then tax is charged on the pre-rebate price.  

California provides multiple examples of situations where an instant rebate is treated as part of the seller's gross receipts and thus subject to tax, including when a distributor sponsors a $2 rebate on dog food and reimburses the seller. 

State differences to watch for when it comes to sales tax on discounts

The rule that sales tax applies after discounts is close to universal. However, how this rule is applied can vary greatly in specific situations, such as coupon reimbursement rules and the treatment of BOGO transactions. 

For example, the table below shows some of the biggest differences between the states.

Sales tax rules when manufacturer coupons are used In most states, including California and Rhode Island, taxes are charged on the full value of the sale when a manufacturer's coupon is used, and the seller will be reimbursed for the discounted amount. In a minority of states, including Texas and Pennsylvania, sales tax is charged on the post-coupon price even if the seller is later reimbursed by the manufacturer.
Sales tax rules on BOGO transactions In some states, including Texas, sellers are treated as having discounted the second item. Sales tax is charged on the price paid for both items. In some states, including Massachusetts, the free item is treated as a promotional item, and the seller is responsible for use tax for consuming the item.

Sellers with physical or economic nexus in multiple states may face substantial challenges in understanding the rules for discounts, coupons, and gift cards because of the widespread variation. 

Partnering with Numeral to automate sales tax compliance ensures that your company always charges the correct tax rate, including when coupons or promotions are involved.

Checking this in your own checkout or accounting system

Managing discounts, coupons, and rebates within your checkout or accounting system can be complicated and can introduce significant potential for error.

In fact, one common mistake is applying sales tax correctly to discounted prices at checkout or when invoicing, but the accounting software incorrectly recalculates tax on the pre-discount total. 

Sellers need to confirm that their storefronts and bookkeeping tools both apply tax consistently to the correct total, and that the storefront correctly applies any discounts when applicable. 

For example, Shopify explains that "When you offer a discount on an order, the discount is applied to the subtotal of the order before taxes, and then any applicable tax is applied afterward," while WooCommerce offers extensions like Cart Discounts for WooCommerce that allow extensive customization of when and how discounts apply. 

When generating reports, Shopify can also provide details on line-item and order-level discounts; total dollar-value reductions applied to sales; and discounts created using discount codes—but all discounts are still applied before tax. 

It's important to ensure your accounting software correctly imports and processes this data, as a mismatch in how your storefront and accounting tools treat sales tax on discounted transactions can create a compliance gap that puts you at risk in an audit.

Sales tax on discounts, coupons, and gift cards FAQs

Still need to know more? Here are the answers to frequently asked questions on sales tax calculations for discounted transactions.

Is sales tax calculated before or after a discount? 

In general, sales tax is calculated after a discount is applied in all states. This means tax is paid based on the actual amount the customer pays, not the list price. 

However, there are variations across states in how specific types of discounts are treated. For example, some states require sales tax to be paid on the pre-coupon price if a seller will be reimbursed for a manufacturer's coupon. BOGO deals are also subject to special tax rules that can sometimes make sellers liable for tax on promotional items.

Do you pay sales tax on the full price if you use a coupon? 

Whether you pay sales tax on the full price or the after-coupon price depends on both the state and the type of coupon. If the coupon is a store coupon, you typically pay tax on the discounted price. If it is a manufacturer's coupon, you'll usually pay tax on the full price, but in a minority of states, you'll pay sales tax on the discounted price as well.

Is sales tax charged on gift cards when you buy them? 

Gift cards are neither a taxable product nor a taxable service, so you do not pay tax on gift cards when you purchase them. When you redeem your gift card, you will be taxed on the full taxable price of the items, with no reduction for the gift card's value. 

Do you pay sales tax when you use a gift card to pay for something? 

If you purchase a taxable item with a gift card, you will pay sales tax on the full taxable price. The gift card is simply a method of payment. It is not a discount, and using a gift card does not result in a reduction of your sales tax bill.

Is a "buy one, get one free" deal taxed differently than a straight discount? 

In some states, a buy-one-get-one-free deal is taxed differently from a straight discount. The seller may be treated as having "consumed" the free item by giving it away as a promotional item, so the seller may owe sales and use tax. However, this is not the case in all states. 

Framing the discount as a two-for-one deal or a percentage-off bundle can also change the tax treatment, resulting in the buyer paying tax on the discounted price of both items.

Are rebates taxed the same as coupons? Not always. 

Rebates are not always taxed in the same way as coupons. Mail-in rebates typically do not reduce the taxable amount of the sale. Instant rebates may or may not reduce the taxable amount of the sale. 

They are often treated the same as manufacturer coupons, and some states charge tax on the pre-coupon price while others charge it on the post-coupon price.
