Facebook Marketplace and Sales Tax: When You Need a Resale Certificate

Facebook Marketplace is the largest casual selling platform in the United States. Over 1.1 billion people use it globally, and tens of millions of Americans buy and sell on it every month. Most of them never think about sales tax. For many, that is fine. But for a growing number of sellers who have turned Marketplace into a real income stream, ignoring sales tax is a mistake that gets more expensive every year.

This guide breaks down exactly when Facebook Marketplace selling triggers tax obligations, who is responsible for collecting, and when a resale certificate becomes essential.

How Facebook Marketplace Handles Sales Tax

The Critical Difference From Other Platforms

Here is where Facebook Marketplace diverges from Amazon, eBay, Walmart, and Poshmark. Those platforms act as marketplace facilitators and collect sales tax on every transaction. Facebook's situation is more complicated.

Facebook Marketplace has two types of transactions:

This distinction is enormous. The majority of Facebook Marketplace transactions happen locally. A buyer messages you, you agree on a price, they drive over and pick up the item, and cash or Venmo changes hands. Facebook is not involved in the payment. Facebook does not collect sales tax. Nobody does.

When Facebook Does Collect Sales Tax

Facebook collects sales tax only when all three of these conditions are met:

1. The transaction uses Facebook's built-in checkout (Commerce)
2. The item is shipped to the buyer
3. The buyer is in a state with marketplace facilitator laws

If you list an item with shipping enabled and a buyer purchases through Facebook's checkout, Facebook calculates and collects sales tax, then remits it to the state. In this scenario, Facebook is acting as the marketplace facilitator, just like Amazon or eBay.

When YOU Are Responsible

For local pickup sales and transactions that happen outside Facebook's payment system, the tax responsibility falls entirely on you. If you are operating as a business (more on that below), you are technically required to collect and remit sales tax on taxable sales in states where you have nexus.

In practice, enforcement of this for small local sales is minimal. But technically, the law does not care how the sale happened. If it is a taxable sale and you have nexus, the obligation exists.

When Does Casual Selling Become a Business?

This is the question that matters most on Facebook Marketplace, because the platform attracts such a wide range of sellers.

Selling Your Own Stuff

If you are clearing out your garage, selling furniture you no longer need, or getting rid of kids' toys they have outgrown, you are a casual seller. This is not a business. You do not need a sales tax permit, a resale certificate, or to collect sales tax.

Most states have "casual sale" or "isolated sale" exemptions that cover exactly this situation. You are disposing of personal property, not running a commercial operation.

Buying to Resell

The moment you start acquiring items specifically to resell them on Facebook Marketplace, you have crossed the line into a business. It does not matter that you are doing it from your kitchen table. It does not matter that you think of it as a side hustle.

Indicators that you are running a business:

• You go to thrift stores, estate sales, or garage sales looking for items to resell
• You buy wholesale lots or liquidation pallets
• You source products from retailers at clearance prices with the intent to flip them
• You have a regular pattern of listing and selling
• You have a profit motive (you are trying to make money, not just clear space)

The Gray Area

Some situations are genuinely ambiguous. You bought 10 pairs of shoes over the last two years and decide to sell five of them. That is probably casual selling. But if you bought 40 pairs of shoes specifically because you knew they would appreciate in value and you could resell them, that is a business.

The IRS and state tax authorities look at the totality of circumstances. Frequency, intent, profit motive, and the scale of activity all factor into the determination.

The $5,000 Threshold and 1099-K Reporting

What Changed

The IRS has been lowering the 1099-K reporting threshold. Here is the progression:

If Facebook (or any payment platform) processes $5,000 or more in payments to you during a calendar year, they will issue you a Form 1099-K. This form reports gross payments, not profit. It goes to both you and the IRS.

What 1099-K Does NOT Mean

Receiving a 1099-K does not automatically mean you owe taxes on the reported amount. If you sold $6,000 worth of personal items that you originally bought for $10,000, you actually have a loss. You still need to report it on your tax return, but you would not owe income tax on those sales.

The issue arises when you cannot prove your cost basis. Without receipts showing what you originally paid for items, the IRS may treat the full amount as income.

What 1099-K DOES Mean

It means the IRS knows about your selling activity. If you have been earning money on Facebook Marketplace and not reporting it, the 1099-K closes that gap. Going forward, every dollar of profit needs to be on your tax return.

How a Resale Certificate Helps Facebook Marketplace Sellers

Tax-Free Sourcing

If you are buying inventory to resell on Facebook Marketplace, a resale certificate lets you purchase that inventory without paying sales tax. This is the same benefit that Amazon, eBay, and Walmart sellers enjoy.

Where to use your certificate:

Savings Example

A furniture flipper who buys $2,000 per month in furniture from thrift stores, estate sales, and retail stores. About $1,400 of those purchases come from sources that charge sales tax.

At an average 7.5% sales tax rate:

• Monthly tax saved: $105
• Annual tax saved: $1,260

For someone flipping furniture as a side business generating $25,000 in annual revenue, that $1,260 represents real margin improvement.

Legitimacy With Suppliers

Having a resale certificate also opens doors. Wholesale suppliers, liquidation companies, and even some thrift store chains take you more seriously when you can produce proper business documentation. It signals that you are a legitimate operation, not a hobbyist trying to get a tax break.

Facebook Shops vs. Facebook Marketplace

Key Differences

Facebook Shops and Facebook Marketplace are not the same thing, and the tax implications differ:

If you run a Facebook Shop with checkout enabled, Facebook acts as a marketplace facilitator on all transactions processed through their system. This is closer to the Amazon/eBay model.

Shopify Integration

Many sellers use Shopify to power their Facebook Shop. In this case, your Shopify store's tax settings control sales tax calculation and collection on orders that originate from Facebook but are processed through Shopify.

State-by-State Considerations

States Where Local Sales Tax Compliance Matters Most

If you are doing significant volume in local Facebook Marketplace sales (not through Facebook checkout), these high-tax states create the biggest exposure:

In these states, failing to collect and remit sales tax on business sales adds up quickly.

States With No Sales Tax

If you operate in Alaska, Delaware, Montana, New Hampshire, or Oregon, sales tax is not a factor for your local transactions. You still benefit from a resale certificate for sourcing in other states.

Practical Steps for Facebook Marketplace Business Sellers

Step 1: Determine if You Are a Business

Ask yourself: Am I regularly sourcing items to resell for profit? If yes, you are a business.

Step 2: Register Your Business

• Choose a structure (sole proprietorship or LLC)
• Register with your state
• Get an EIN from the IRS if forming an LLC

Step 3: Get Your Tax Documents

Apply for Your Resale Certificate

Step 4: Set Up Basic Accounting

Track every purchase and every sale. Use a simple spreadsheet at minimum. Record:

• Date of purchase and source
• Item description and cost
• Whether you paid sales tax (should be $0 with your certificate)
• Date and price of sale
• Platform used (Marketplace, Shops, etc.)
• Fees paid
• Net profit

Step 5: Understand Your Collection Obligations

For shipped items through Facebook checkout, Facebook handles it. For everything else, you are technically responsible. Consult with a tax professional about how to handle local sales in your state.

Common Questions

"I only sell locally for cash. Does the IRS know?"

The IRS may not have direct visibility into cash transactions, but underreporting income is still illegal. If your spending does not match your reported income, that can trigger scrutiny. The 1099-K threshold is also catching more sellers who use digital payments like Venmo and PayPal.

"Do I need to charge sales tax on a $20 item I sell locally?"

Technically, if you are operating as a business, yes. In practice, enforcement on small individual transactions is rare. But the obligation exists, and it scales. Selling 500 items at $20 each is $10,000 in revenue, and the tax on that is real money.

"Can I use a resale certificate to buy things on Facebook Marketplace?"

Generally no. Individual sellers on Facebook Marketplace are not set up to process tax-exempt transactions. Your certificate is for use with established businesses: retail stores, wholesalers, thrift stores, and liquidation companies.

"What if I sell on Facebook Marketplace AND Amazon?"

Your resale certificate works across all your channels. Buy inventory tax-free with your certificate, then sell on whatever platform you choose. Just remember that Amazon and Facebook have different sales tax collection rules, and your nexus obligations are based on total sales across all platforms.

Record Keeping Matters

Keep records for at least four years (seven is safer). An audit of your Facebook Marketplace business would require you to prove:

• Items purchased were genuinely for resale
• Sales tax was not charged on exempt purchases (or was properly exempted)
• Income was accurately reported
• Any sales tax you collected was remitted

Without records, an auditor can assess taxes based on estimates, which almost always costs you more than the actual amount owed.

Take the Right Step

If you have moved beyond casual selling and are running a real reselling business on Facebook Marketplace, get your tax situation in order. A resale certificate is the first and most impactful step you can take.
