Stores charge for bags because a state, county, or city law tells them to. There is no federal rule on this. More than a dozen states have banned single-use plastic bags outright, and hundreds of local governments have layered on per-bag fees at checkout. The reason stores charge for bags, in nearly every case, is that the jurisdiction you’re shopping in has decided a small price tag is the most effective way to cut plastic waste and get people bringing their own bags.
The Two Legal Models Behind the Charge
Bag laws come in two basic shapes. A ban prohibits stores from handing out single-use plastic bags at all. A mandatory fee requires the store to charge a set amount for each checkout bag it provides. Plenty of jurisdictions do both: they ban plastic and require a fee on paper, so stores can’t just swap one disposable option for another.
A few states have also gone back and tightened their original rules. Early bans sometimes let stores sell thicker plastic bags labeled “reusable” for the same small fee, which meant shoppers were still walking out with single-use plastic under a new name. Newer legislation in those states bans thick plastic checkout bags too, leaving paper or genuinely durable reusable bags as the only options.
Why a Fee Instead of Just a Ban
The fee is a nudge. When a bag that used to be free suddenly costs a dime, most shoppers start remembering their own. That behavioral shift is the whole point of the law.
The evidence that it works is strong. One analysis of bans in a handful of states and cities found they eliminated roughly six billion single-use plastic bags per year. A study of one state’s ban found plastic bag use dropped 91% after the law took effect.
The environmental case driving these laws is straightforward. The typical plastic bag is used for the walk from store to car to kitchen, then thrown out. Plastic degrades slowly, and as it breaks apart it produces microplastics and nanoplastics that spread into marine and land environments.1Woods Hole Oceanographic Institution. Does Plastic Last for Thousands of Years in the Environment? More than 1,500 species in marine and land environments are known to ingest plastics, and producing plastic products accounted for an estimated 3.4% of global greenhouse gas emissions in 2019.2U.S. Environmental Protection Agency.

Where These Rules Apply
Whether you pay for a bag depends entirely on where you’re standing. Cross a county line and the rules can flip.
At least eight states have enacted outright bans on single-use plastic bags, with more following in recent years to bring the total above a dozen.3National Conference of State Legislatures. State Plastic Bag Legislation On top of that, over 500 municipalities in 28 states had some form of plastic bag legislation in effect as of 2021, and the number has kept growing. Some of those local laws impose fees without banning plastic; others mirror the stricter statewide bans.
Six states have gone the other direction. They’ve passed preemption laws that block their own cities and counties from enacting any bag bans or fees.3National Conference of State Legislatures. State Plastic Bag Legislation If you shop in one of those states, local governments can’t impose a bag charge no matter how the city feels about it. That’s why neighboring states can have completely opposite rules on the same shelf of groceries.
What Triggers the Fee and What Doesn’t
Most bag fees run between 5 and 12 cents per bag, with 10 cents the most common amount. Some jurisdictions have moved higher. The charge applies to checkout bags the store provides to carry your purchases, whether plastic (where still legal) or paper. The fee typically applies at every point of sale, meaning in-store, pickup, and delivery orders all trigger it on qualifying bags.
Not every bag counts. Most laws exempt:
- Produce and bulk bags, the thin kind you tear off a roll for loose fruit, vegetables, nuts, or grains
- Bags for uncooked meat, poultry, or seafood, to prevent contamination
- Pharmacy bags containing prescription medication
- Specialty bags for dry cleaning or flowers
- Any bag you bring from home
The dividing line is usually whether the bag is there to carry your purchases out of the store, or just to keep products safe or separated inside it. The spinach bag from the produce aisle is exempt. The bag the cashier puts it into at checkout is not.
Many laws also require stores to itemize the bag fee on your receipt, so you can see exactly what you were charged. Where paper bags are the alternative to banned plastic, those paper bags often have to meet recycled-content standards to qualify.
Where the Money Goes
This varies by jurisdiction. In some places, the store keeps the entire fee to cover the cost of providing bags and running the program. In others, the store sends a share to the local government and keeps the rest for administrative costs. Government shares typically go toward environmental programs, litter cleanup, or free reusable bags for low-income communities.
It’s worth knowing that stores have always paid for bags, roughly 2 to 5 cents each for plastic and more for paper. Before fee laws, those costs were baked into product prices, so every shopper subsidized bags whether they used them or not. The fee shifts that cost onto the people actually taking a bag.
In some jurisdictions, bag fees are treated as taxable retail sales, so sales tax applies on top of the per-bag charge. Whether you see tax on your bag fee depends on where you shop.
If You Pay With SNAP
SNAP benefits cannot be used to cover bag fees. The USDA’s Food and Nutrition Service has stated that grocery bag fees may not be paid with SNAP, and the agency has no authority to exempt SNAP recipients from the charge.4Food and Nutrition Service. SNAP Retailer Notice – Bag Fees, Sales Tax, Seasonal Items You’ll need to pay the fee separately with cash, a credit card, or a non-SNAP debit card.
One benefit does carry over: stores that offer a discount to customers who bring their own bags must extend the same discount to SNAP customers.4Food and Nutrition Service.

Some communities hand out free reusable bags through local programs or food banks.
