Yes. Square reports to the IRS by filing Form 1099-K when your account crosses the federal reporting threshold: more than $20,000 in gross payments and more than 200 transactions in a single calendar year. Both conditions have to be met. Some states set their own lower triggers, so you can receive a 1099-K from Square even when your federal numbers are well below those lines. And regardless of whether a form is ever filed, the income you earn through Square is taxable.
The Federal Threshold That Triggers a 1099-K
The threshold has been a moving target since 2021, so it is worth being precise about where it landed. The American Rescue Plan Act of 2021 tried to replace the long-standing $20,000-and-200-transaction rule with a single $600 threshold. The IRS then delayed that change year after year, publishing a phase-in plan that would have started at $5,000 for 2024 and $2,500 for 2025. None of those interim numbers ever became the final rule.
In July 2025, the One, Big, Beautiful Bill Act was signed into law and reinstated the original threshold retroactively to the 2022 tax year.1Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill; Dollar Limit Reverts to $20,000 The $600 threshold is off the table. For 2026 and beyond, Square is required to file a 1099-K for you only if your account exceeds both $20,000 in gross payments and 200 transactions during the year.2Internal Revenue Service. Form 1099-K FAQs: General Information
Both numbers matter. Process $30,000 across 150 transactions and no federal 1099-K is required. Run 250 transactions totaling $15,000 and the answer is the same. You have to cross both lines.
State Rules Can Pull You in Sooner
Several states set their own 1099-K thresholds below the federal one, and a handful require reporting at as little as $600 with no transaction minimum. Square follows state law where it applies, so you can receive a 1099-K driven entirely by your state’s rules even when your federal numbers are nowhere near $20,000.3Internal Revenue Service. Understanding Your Form 1099-K
Receiving a state-triggered 1099-K does not change how much tax you owe. It only means the IRS and your state tax agency have paperwork about your sales at a lower volume than the federal rule alone would require.
What the Form Actually Shows
Form 1099-K reports the gross amount of your payment activity for the year.4Internal Revenue Service. About Form 1099-K, Payment Card and Third Party Network Transactions That is the total your customers paid before anything is taken out. Square’s processing fees, refunds, chargebacks, shipping costs, discounts, and your cost of goods sold are all still baked into that number.5Internal Revenue Service. Instructions for Form 1099-K (Rev. March 2024)
The practical consequence: the figure on your 1099-K will almost always look larger than what you actually took home. That gap is normal. The form gives the IRS a baseline to check against your return; it does not calculate what you owe.2Internal Revenue Service. Form 1099-K FAQs: General Information
When Square is required to send a 1099-K, the deadline is January 31 of the following year.6Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns – For Use in Preparing 2026 Returns For 2026 activity, expect the form by January 31, 2027.
You Owe Tax Even If Square Never Files a Form
The threshold controls paperwork, not tax liability. Every dollar of business income you earn through Square is taxable, whether or not a 1099-K is ever filed. A seller who processes $8,000 through Square owes the same tax on that income as one who processes $80,000. The reporting rule does not carve out a tax-free zone below $20,000.
Sole proprietors and single-member LLCs report their Square revenue and expenses on Schedule C (Form 1040).7Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025) Your taxable profit is gross income minus ordinary business expenses: Square’s processing fees, inventory, supplies, advertising, and similar costs. If you received a 1099-K, treat it as a reconciliation tool: your Schedule C gross receipts need to match or exceed the amount on the form, and your deductions explain the drop from that gross figure down to net profit.
On top of income tax, self-employment tax applies to your net earnings at 15.3% — 12.4% for Social Security up to the annual earnings cap, plus 2.9% for Medicare with no ceiling. You compute it on Schedule SE and deduct the employer-equivalent half when figuring adjusted gross income.8Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
If you expect to owe $1,000 or more for the year, the IRS wants quarterly estimated payments rather than a single April payment.9Internal Revenue Service. Estimated Taxes Once self-employment tax is added to income tax, most active Square sellers land above that threshold.
Personal Payments and Forms Sent in Error
Form 1099-K is meant to cover payments for goods or services. Personal transfers — reimbursing a friend, splitting a bill, receiving a gift — should not appear on it.3Internal Revenue Service. Understanding Your Form 1099-K Square is a business payment platform, so this issue comes up less than it does with peer-to-peer apps, but it can still happen. Selling a personal item at a loss is not taxable even if the proceeds land on a 1099-K; a personal item sold at a gain is.
If the gross amount on your 1099-K is wrong — duplicates, refunds not backed out, personal payments included — contact Square first and ask for a corrected form. Square’s contact information appears in the upper left corner of the form. If a correction is not issued, you can neutralize the incorrect amount on your return by reporting it on Schedule 1 as other income and entering an equal offsetting adjustment, so your adjusted gross income is unaffected.10Internal Revenue Service. Actions to Take if a Form 1099-K Is Received in Error or With Incorrect Information
Backup Withholding When Your Taxpayer ID Is Off
When you set up your Square account you provide a Taxpayer Identification Number, which functions like an electronic Form W-9.11Internal Revenue Service. About Form W-9, Request for Taxpayer Identification Number and Certification For sole proprietors, that is usually a Social Security Number; for corporations and LLCs taxed as separate entities, an Employer Identification Number.12Internal Revenue Service. U.S. Taxpayer Identification Number Requirement
If your TIN is missing or does not match IRS records, Square is required to withhold 24% of your gross payments and send that money to the IRS.13Internal Revenue Service. Backup Withholding This is backup withholding, not an extra tax. The amount held back appears in Box 4 of your 1099-K and credits against your tax liability when you file.5Internal Revenue Service. Instructions for Form 1099-K (Rev. March 2024) It still hurts cash flow, so keeping your account information accurate is worthwhile.
What the IRS Does With the Report
The IRS runs an Automated Underreporter program that compares income reported by third parties against what you claim on your return.14Internal Revenue Service. Topic No. 652, Notice of Underreported Income – CP2000 When your Schedule C gross receipts do not match or exceed the amount Square reported on your 1099-K, the mismatch is flagged and can generate a CP2000 notice proposing additional tax, interest, and penalties.
A CP2000 is not an audit, and it is not always right. But the fix is easier before it happens: make sure the gross receipts you report account for the full amount on the 1099-K, and use your expense deductions to explain the difference between that gross figure and your net profit.
