Quick Answer
Facebook Marketplace sales are taxable if you sell for profit or as a business. Personal items sold for less than you paid are not taxable. For 2026, Facebook will send 1099-K forms if you receive over $5,000 in payments, but you owe taxes on all business income regardless.

People just starting to sell on Facebook Marketplace who need to understand when sales become taxable
When Facebook Marketplace sales become taxable
The key question isn't whether you're selling on Facebook Marketplace — it's whether you're selling for profit. The IRS distinguishes between personal property sales (usually not taxable) and business activities (always taxable).
Personal property sales vs. business income
Not taxable: Selling personal items for less than you originally paid. This includes used furniture, clothes, electronics, or household goods where you're taking a loss.
Taxable: Any sales where you make a profit, including:
According to IRS Publication 535, if you buy and sell items with the intent to make a profit, you're operating a business and must report all income.
Example: Personal vs. business sales
Personal sale (not taxable):
Business sale (taxable):
The new 1099-K rules for 2026
Starting in 2026, Facebook (through its payment processor) will send you a 1099-K if you receive more than $5,000 in payments during the year. This is a significant change from the previous $20,000 threshold.
Important: The 1099-K shows gross payments received, not your profit. You still need to calculate your actual taxable income by subtracting what you originally paid for items.
How to calculate your taxable income
For business sales, your taxable income is sales price minus your cost basis:
In this example, you'd owe taxes on $2,800 of profit, not the full $4,300 in sales.
Self-employment tax considerations
If your Facebook Marketplace activity constitutes a business (regular sales for profit), your net earnings are subject to self-employment tax of 15.3% in addition to regular income tax.
However, if your net earnings from self-employment are less than $400 per year, you don't owe self-employment tax — but you still owe regular income tax on the profit.
Record-keeping requirements
Even if you don't receive a 1099-K, you must report all business income. Keep records of:
Red flags that indicate business activity
The IRS looks for these patterns to determine if you're running a business:
What you should do
1. Track every sale and purchase from day one — don't wait until tax time
2. Use our freelance dashboard to categorize income and expenses automatically
3. Set aside 25-30% of profits for taxes if you're making money consistently
4. Consider making quarterly estimated tax payments if you expect to owe more than $1,000

Key takeaway: Facebook Marketplace sales are taxable if you make a profit or operate as a business. Even without a 1099-K, you must report all business income. Personal items sold at a loss are not taxable.

Non-US citizens or residents selling on US-based Facebook Marketplace
US tax obligations for international Facebook Marketplace sellers
As an international seller on Facebook Marketplace, your US tax obligations depend on whether you're a US tax resident and where your business activities occur. Sales to US customers may create US tax liabilities even if you're not a US citizen.
Determining your US tax obligations
If you're a US tax resident (green card holder or meet substantial presence test), you report Facebook Marketplace income the same as US citizens — all worldwide income is subject to US tax.
If you're a non-resident alien, you may still owe US taxes if:
Effectively Connected Income (ECI) rules
Under IRC Section 864, if your Facebook Marketplace sales constitute a US trade or business, the income is "effectively connected" with the US and subject to regular US income tax rates (not the 30% withholding rate for passive income).
Factors that indicate a US trade or business:
Example: Canadian seller with US customers
A Canadian resident sells handmade items on Facebook Marketplace, shipping to US customers:
If operating from Canada with occasional US sales, likely no US tax obligation. If traveling to the US regularly for sourcing or maintaining US inventory, may create US tax liability.
State sales tax considerations
Beyond income tax, international sellers may have state sales tax obligations in states where they have "economic nexus" — typically $100,000+ in sales or 200+ transactions annually to that state's customers.
Many states now require sales tax registration and collection for remote sellers, including international sellers shipping to US customers.
What you should do
1. Determine if your activities create US tax obligations based on location and scale
2. Keep detailed records of US vs. non-US sales and business activities
3. Consult a tax professional if you have significant US sales or business presence
4. Research state sales tax requirements in states where you have customers
Key takeaway: International Facebook Marketplace sellers may owe US taxes if they conduct regular business activities in the US. The key factors are physical presence, inventory location, and whether sales constitute "effectively connected income."

People with full-time jobs who sell on Facebook Marketplace as supplemental income
Managing Facebook Marketplace income with your day job
As a side hustler combining W-2 employment with Facebook Marketplace sales, your main concerns are estimated tax payments and staying organized for tax time. Your employer's payroll withholding only covers your salary, not your side income.
When your side hustle affects your tax bracket
Adding Facebook Marketplace profit to your W-2 income might push you into a higher tax bracket. More importantly, it creates additional tax liability that your employer isn't withholding for.
Example: $60,000 W-2 salary + $4,000 Facebook Marketplace profit:
Estimated tax payment strategy
If you expect to owe more than $1,000 in additional taxes from your side hustle, you should make quarterly estimated tax payments to avoid underpayment penalties.
Alternatively, you can increase your W-4 withholding at your day job to cover the additional tax liability. Use the IRS Tax Withholding Estimator to determine the right adjustment.
Business expense opportunities
Unlike your W-2 job, Facebook Marketplace sales allow you to deduct business expenses:
Keeping your side hustle organized
The biggest mistake side hustlers make is poor record-keeping. Set up systems from the beginning:
1. Separate bank account for marketplace transactions (optional but helpful)
2. Expense tracking app or spreadsheet for all business costs
3. Receipt storage system (photos or physical filing)
4. Monthly profit/loss reviews to estimate quarterly taxes
Scaling considerations
If your Facebook Marketplace side hustle grows significantly, consider:
What you should do
1. Set aside 25-30% of net profit for taxes immediately after each sale
2. Track all business expenses to maximize deductions
3. Make quarterly estimated payments or adjust W-4 withholding if you owe over $1,000
4. Use our quarterly estimator to calculate how much to set aside
Key takeaway: Side hustlers must manage estimated taxes on Facebook Marketplace profits since employers don't withhold for side income. Set aside 25-30% of net profit and track all business expenses to maximize deductions.
