Yes. Square reports to the IRS by filing Form 1099-K when a seller’s account crosses the federal reporting threshold in a calendar year: more than $20,000 in gross payments and more than 200 separate transactions. Both conditions have to be met for the federal rule to kick in. Some states require Square to file at much lower amounts, and regardless of whether a form is ever generated, every dollar of business income you take in through Square is taxable.
What Square Actually Sends to the IRS
Form 1099-K, Payment Card and Third Party Network Transactions, is the document Square files with the IRS and sends to you when your account crosses the reporting threshold.1Internal Revenue Service. About Form 1099-K, Payment Card and Third Party Network Transactions The number on it is the “gross amount” of your transactions for the year. That is the total dollar value of what customers paid you before anything comes out. Square’s processing fees, refunds you issued, chargebacks, shipping, discounts, and your cost of goods sold are not subtracted.2Internal Revenue Service. Instructions for Form 1099-K (Rev. March 2024)
So the figure the IRS sees almost always looks bigger than your real profit. That gap is normal. You reduce it on your tax return by deducting your business expenses; the 1099-K itself does none of that math.3Internal Revenue Service. Form 1099-K FAQs: General Information The form exists to give the IRS a baseline to compare against what you report.
When Square is required to send you a 1099-K, the deadline is January 31 of the year following the tax year.4Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns – For Use in Preparing 2026 Returns For the 2026 tax year, that means by January 31, 2027.
The Federal Threshold and the $600 Reversal
If you have read conflicting things about Square and a $600 reporting floor, here is what happened. The original federal rule, in place for over a decade, required payment platforms to file a 1099-K only when a seller received more than $20,000 in gross payments and had more than 200 transactions in a year. The American Rescue Plan Act of 2021 tried to replace that with a flat $600 threshold and no transaction minimum, which would have swept in almost every Square seller.
The IRS delayed the $600 rule repeatedly and announced phase-in numbers of $5,000 for 2024 and $2,500 for 2025. None of those lower figures became the final law. In July 2025, the One, Big, Beautiful Bill Act was signed, and it retroactively reinstated the original $20,000-and-200-transaction threshold back to the 2022 tax year.5Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill; Dollar Limit Reverts to $20,000 The $600 federal threshold is dead.
So for 2026 and beyond, Square files a federal 1099-K for you only when you exceed both $20,000 and 200 transactions in the same calendar year.3Internal Revenue Service. Form 1099-K FAQs: General Information Process $30,000 across 150 transactions? No federal form. Run 250 transactions totaling $15,000? Same answer. You have to cross both lines.
States That Trigger Reporting at Lower Amounts
Several states keep their own 1099-K thresholds that sit well below the federal one. A handful set theirs as low as $600 with no minimum transaction count. You can get a 1099-K from Square because of where you live even when your activity falls well below the federal line.6Internal Revenue Service. Understanding Your Form 1099-K – Section: Reporting Threshold The IRS itself notes that payment platforms may issue the form at amounts below the federal threshold, and state law is the most common reason.
Getting a 1099-K because of a state rule does not change how much tax you owe. It just means the IRS and your state tax agency are receiving paperwork about your sales at a lower volume.
You Owe Tax Even Without a 1099-K
The reporting threshold decides when Square has to generate paperwork. It does not create a tax-free zone underneath it. A seller who runs $8,000 through Square owes tax on that income the same way a seller running $80,000 does. If you earn business income through the platform, it belongs on your return whether or not a form shows up in January.
Sole proprietors and single-member LLCs report that revenue and the expenses that go with it on Schedule C (Form 1040).7Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025) On top of regular income tax, net earnings from self-employment are subject to self-employment tax at 15.3% (12.4% Social Security up to the annual cap, 2.9% Medicare with no cap).8Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) If you expect to owe $1,000 or more after withholding and credits, the IRS wants quarterly estimated payments rather than one lump at filing time.9Internal Revenue Service.

Personal Payments Should Not Be on the Form
Form 1099-K is meant to cover payments for goods or services. Personal transfers like splitting a dinner bill or getting reimbursed for rent should not appear on it.10Internal Revenue Service. Understanding Your Form 1099-K Square is primarily a business payment platform, so most activity on it is business activity by default. If you sold a personal item at a loss and the proceeds nevertheless appear on your 1099-K, you can zero out that income on Schedule 1 by reporting the amount as other income and entering an equal offsetting adjustment.11Internal Revenue Service. Actions to Take if a Form 1099-K Is Received in Error or With Incorrect Information A personal item sold at a gain, though, is taxable.
Your Taxpayer ID and the 24% Backup Withholding Risk
Square collects your Taxpayer Identification Number when you set up your account, the digital equivalent of a Form W-9.12Internal Revenue Service. About Form W-9, Request for Taxpayer Identification Number and Certification For sole proprietors, that is usually your Social Security Number. For corporations and LLCs taxed as separate entities, it is an Employer Identification Number.13Internal Revenue Service. U.S. Taxpayer Identification Number Requirement
If you never provide a valid TIN, or the number you gave does not match IRS records, Square is required to withhold 24% of your gross payments and send that money straight to the IRS.14Internal Revenue Service. Backup Withholding – Section: What Is Backup Withholding? This is backup withholding, and it continues until the mismatch is fixed. The amount shows up in Box 4 of your 1099-K and you get credit for it on your return.2Internal Revenue Service. Instructions for Form 1099-K (Rev. March 2024) It is not an extra tax, just a forced prepayment, but losing nearly a quarter of each deposit creates a real cash-flow problem. Keep your account information current.
If the 1099-K Square Sent You Is Wrong
If the gross amount is incorrect because of duplicate transactions, refunds that were not backed out, or personal payments mixed in, contact Square first. The issuer’s name and phone number sit in the upper-left corner of the form. Ask for a corrected 1099-K and keep copies of everything.11Internal Revenue Service. Actions to Take if a Form 1099-K Is Received in Error or With Incorrect Information
If Square will not or cannot reissue the form, you can neutralize the error on your return. Report the incorrect amount on Schedule 1 (Form 1040), Part I, Line 8z as “Form 1099-K Received in Error,” then enter an equal offsetting deduction on Part II, Line 24z with the same description. The two entries cancel, leaving your adjusted gross income unchanged.11Internal Revenue Service. Actions to Take if a Form 1099-K Is Received in Error or With Incorrect Information The approach works whether the entire form was issued in error or the amount is simply inflated.
How the IRS Uses What Square Reports
The IRS does not just file your 1099-K away. An automated system, the Automated Underreporter program, compares the income third parties report about you against what you claimed on your return.15Internal Revenue Service. Topic No. 652, Notice of Underreported Income – CP2000 When the figures do not match, a tax examiner reviews the discrepancy. If the IRS concludes you underreported, you receive a CP2000 notice proposing additional tax, interest, and possibly penalties.
A CP2000 is not an audit, and it is not always right. For Square sellers, the usual trigger is failing to show gross receipts on Schedule C that at least equal the 1099-K amount. Even when your net profit after deductions is small, the gross receipts line has to account for the full amount Square reported. If it does not, the matching system flags it automatically. That is the practical reason to keep your Square transaction reports, your bank deposits, and your expense receipts organized: closing the gap between the gross number the IRS received and the net number on your return is something you may be asked to explain.
