Running an Online Business Abroad? Form 1099-K and Your U.S. Taxes

If you run an online business, freelance, or sell goods while living abroad, you might receive IRS Form 1099-K. It reports payment transactions processed through platforms like PayPal, Stripe, or online marketplaces, rather than your actual profit or amount you ultimately owe in tax. Because Form 1099-K reflects total transactions rather than net earnings, it can give a misleading picture of your income at first glance. 

For taxpayers managing income across borders, knowing how Form 1099-K fits into your U.S. tax return is key to reporting income correctly, claiming the right deductions, and avoiding unnecessary issues with the IRS. 

What is Form 1099-K? 

Form 1099-K is issued by a payment settlement entity, such as a payment processor or platform classified as a third-party settlement organization (TPSO), to report payments you receive through card payments, payment apps, and online marketplaces. Simply put: it tracks the money flowing through platforms that process payments on your behalf. Reporting thresholds differ by payment type: 

• Payment card transactions: This includes credit cards, debit cards, and gift cards. These transactions have no minimum threshold and are reported regardless of amount. 
• TPSO transactions: These third-party network transactions are typically through online marketplaces or payment apps. They are reported if gross payments exceed $20,000 and transactions exceed 200 in the calendar year. 

This includes:

• Sales of goods through online marketplaces (like Etsy or eBay)
• Freelance or gig work paid through apps (like Uber or DoorDash)
• Payments processed via platforms (like Stripe or Venmo)

Unlike Form 1099-NEC, which reports payments for services, and Form 1099-MISC, which reports certain types of miscellaneous income, Form 1099-K focuses specifically on payments handled by third-party payment platforms.

For example, if you have a small business on Etsy and sell $12,000 worth of handmade jewelry but spend $3,000 on supplies and shipping, your 1099-K will report $12,000. Your actual taxable income, however, is $9,000 after expenses. 

How U.S. expats should report 1099-K income 

If you live abroad and earn income online, you’re generally still required to report that income on your U.S. tax return — Form 1099-K is only part of that picture. To report it correctly, you’ll need to go beyond the form and work through your actual earnings step by step. 

Step 1: Identify your total payments 

Start by reviewing the total payment reported on your 1099-K for the tax year. Then separate: 

• Business transactions (taxable)
• Personal transactions (generally nontaxable) 

Because Form 1099-K can include payments that aren’t actually taxable income, separating them early helps ensure you don’t overreport your earnings.

Step 2: Calculate net income 

Subtract your business expenses, such as: 

• Platform and processing fees 
• Supplies and inventory 
• Shipping and fulfillment costs
• Equipment or tools

Only your net income (not gross receipts) is used to calculate your tax liability. 

Step 3: Report income correctly 

Most freelancers and business owners report this income on Schedule C, which is filed with Form 1040. This is where you reconcile your gross income, expenses, and net profit as part of your overall business tax reporting. 

In select cases, such as one-off or non-business transactions, income may instead be reported on Schedule 1 as “other income.” However, most 1099-K income tied to ongoing work or sales activity is considered business income and belongs on Schedule C. 

Step 4: Apply expat tax benefits

Once you’ve calculated your net income, you may be able to reduce your U.S. tax liability using expat-specific tax provisions, including: 

• Foreign Earned Income Exclusion (FEIE): May allow you to exclude a portion of earned income from U.S. taxation if you meet residency or physical presence tests. 
• Foreign Tax Credit (FTC): Offsets U.S. taxes by providing a credit for income taxes paid to a foreign country, which can be especially useful if you’re living in a higher-tax jurisdiction. 

Choosing between the FEIE and FTC — or using a combination of both — can significantly affect how much of your income is ultimately taxed. 

If you’re self-employed, your net earnings may still be subject to self-employment tax, even if the FEIE applies. 

Common mistakes to avoid 

Form 1099-K reporting can lead to errors if you rely on the form without understanding what it includes. These mistakes can result in overstated income or compliance issues with IRS reporting requirements. 

Common mistakes include: 

• Reporting gross payments as profit: Treating total payments as taxable income without subtracting tax deductions can significantly inflate your tax bill.
• Including personal transactions as income: Transfers between friends, family reimbursements, or payments for personal items are generally nontaxable but may still appear on platform reports. 
• Ignoring income below reporting thresholds: Even if you do not receive a 1099-K, all worldwide income must still be reported. 
• Failing to reconcile multiple platforms: If you receive income from multiple payment providers or marketplaces, failing to track the number of transactions accurately can lead to inconsistencies. 
• Overlooking self-employment obligations: Many freelancers or independent contractors forget that net earnings may still be subject to self-employment tax, even if income is excluded under the FEIE. 

When to seek a tax professional 

Certain situations make it valuable to work with a tax professional rather than navigating Form 1099-K and expat tax rules alone. Consider professional guidance if you: 

• Have multiple 1099-K forms from different platforms: Coordinating income and expenses across multiple third-party payment platforms can be tricky and prone to errors. 
• Operate a business or freelance across countries: Determining which income qualifies for FEIE, which is subject to FTC and fully taxable requires careful tracking. 
• Mixing earned income and investment income: Combining business earnings, dividends, and long-term capital gains can affect how marginal rates and credits apply. 
• Plan to claim significant deductions or exclusions: Complex deductions (like home office, supplies, or international business expenses) can impact your total tax liability if it isn’t applied correctly. 
• Want to reduce audit risk: A professional can help you ensure your numbers reconcile with 1099-K reports and other IRS records, minimizing the chance of notices or penalties. 

Don’t let Form 1099-K complicate your tax reporting

Form 1099-K can feel strange at first, but it’s simply a tool used for federal tax information rather than a new tax law you have to navigate. By understanding what it reports, tracking your expenses, and applying exclusions and credits where applicable, U.S. expats can approach tax filing with confidence.
