If you’re planning to open a dropshipping store in the United States, the resale certificate should be on your to-do list. This paper lets you buy products from your suppliers without paying sales tax, as long as you plan to sell them to customers. Using platforms like Doba makes the certificate even more important, since many suppliers won't onboard you without one.
This post shows you why the resale certificate is key, the steps to apply for it, where to track down the forms for your state, and the common pitfalls to dodge. We’ll also clarify the difference between a business license and a resale certificate, plus tips for staying on the right side of the law once you have your certificate in hand.
What Is a Resale Certificate and Why Do You Need One?
A resale certificate (sometimes called a reseller’s permit or a sales tax exemption certificate) is a simple document handed out by your state’s tax office. It lets your business buy products without paying sales tax upfront. Why? Because you’re buying them to sell to someone else, and you’ll charge sales tax to your customer instead.
Let’s say you’re using Doba to find pet supplies or workout gear to sell on your Shopify store. When you order those products from the supplier, you shouldn’t pay sales tax. Your customer will pay sales tax when they check out, and you’ll send that tax to the state later.
Why You Need a Resale Certificate
Stops double taxation: You won’t pay tax when buying products and again when selling them.
Makes you supplier-friendly: Suppliers often ask for it before they’ll let you order.
Keeps taxes organized: Your tax forms will look cleaner and more professional.
Legitimizes your business: Vendors see you as a real business and not a hobby.
How a Resale Certificate Helps With Supplier Approval
Most U.S. suppliers want a resale certificate before they’ll sell to dropshippers. This is especially true when you’re buying wholesale items directly or working with a manufacturer. They want proof that you’re reselling, not using the stock for personal use. Having the certificate ready makes the supplier relationship smoother.
On platforms like Doba, suppliers mark which items need a resale certificate. If you upload your certificate during account setup or when onboarding with a supplier, you’ll avoid hold-ups and unlock a bigger product range for your store.
Having the resale certificate handy shows suppliers you’re running a serious business, not just a casual shopper.
Steps to Register for a Resale Certificate
Getting a resale license for your online store is simple, but every state has its own rules. Here’s a general guide that works for most states.
1. Register Your Business Entity
You need a legal business structure before you can apply for the resale certificate. Your main options are:
Sole Proprietorship (quick to set up, some liability protection)
Limited Liability Company (LLC) (popular for online stores)
Corporation (better for larger companies or those with investors)
You can usually register with your state’s Secretary of State’s office.
2. Apply for an EIN from the IRS
Your Employer Identification Number (EIN) acts like a Social Security number for your business. You’ll need it for the resale certificate, to open a business bank account, and for filing taxes. You can get it for free on the IRS website.
You can get your EIN by filling out the online form at the IRS EIN portal, and it won’t cost you a dime.
Save your EIN confirmation letter in a safe place; most state tax forms will ask for it.
3. Get a Resale Certificate or Sales Tax Permit
Head to your state’s Department of Revenue or Taxation office to apply. Some states issue a resale certificate by themselves, while others add it to the sales tax permit.
The process is usually:
Fill out the online form
Enter your EIN, business name, and address
Describe your business type (like online retail)
A few states charge a small fee, but most give the certificate for free.
4. Share Your Certificate with Suppliers
After you receive your certificate, download it and keep it in your business files. Next, make sure you:
Upload it to your Doba dashboard, where it asks for the certificate
Hand it to US suppliers when they ask
Save a copy in cloud storage or a secure business folder
Where to Apply by State
Every state has its portal for resale certificate registration. Here’s where to go in a few states:
California: cdtfa.ca.gov
Texas: comptroller.texas.gov
Florida: floridarevenue.com
Delaware, Oregon, Montana, New Hampshire, and Alaska don’t collect sales tax, so they don’t issue resale certificates.
To find your state’s application, type “resale certificate [your state]” into a search engine or check your state’s Department of Revenue site.
Difference Between a Resale Certificate and Business License
A business license and a resale certificate are two different tools for running a business, but people sometimes mix them up:
A business license gives you the green light to operate in your city or state. You might need to register with your city or county separately, depending on local rules.
A resale certificate lets you buy products for resale without paying sales tax. You promise the state you’ll charge tax when you sell those products to customers and pass the tax along to the state.
Many states require you to have both. For example, in some states you can’t even apply for a resale certificate without first registering your business with local authorities.
How to Stay Compliant
Getting your certificate is just the first step. To keep out of legal or financial trouble, you need to keep up with ongoing responsibilities.
Compliance Tips:
Collect Sales Tax Where You Have Nexus: If you have a real presence, like a store or a certain sales volume, in a state, you probably need to collect and send sales tax from customers in that state.
File Sales Tax Returns: States usually want you to file returns on a regular schedule—monthly, quarterly, or annually—based on how much you sell.
Maintain Organized Records: Keep copies of all purchase receipts, resale certificates, and tax returns in a safe, easy-to-find place.
Be timely with Renewals: A few states want you to renew every year, and others want it every two years.
Use Smart Tax Tools: Programs like TaxJar, Avalara, and QuickBooks Commerce can help you track sales and keep reports in line with what states want.
Being compliant not only keeps you clear of fines; it also keeps your suppliers and marketplaces happy.
Common Mistakes to Avoid
If you’re new to ecommerce and dropshipping, handling resale documents can trip you up. Here’s what to avoid:
Forget to Renew: In some states, your resale certificate is worthless if you let the term run out.
Keep it to Yourself: Having the certificate isn’t enough. You have to send it to every supplier that asks for it.
Look Creditable with Resale Certificates
Having a resale certificate for dropshipping certain products is a must if you want to save on taxes and look creditable. Go without one, and you might end up paying sales tax on every item or get turned away by suppliers. Get one, and you’ll earn trust, cut costs, and keep everything running smoothly.
