If you hire independent contractors or work as one, the core set of tax forms is short: the business collects a Form W-9 from each contractor and files a Form 1099-NEC for anyone it paid $2,000 or more in 2026 (up from the old $600 threshold), and the contractor reports that income on Schedule C, pays self-employment tax on Schedule SE, and sends in quarterly estimates on Form 1040-ES. Everything else on either side is a variation for a specific situation.1Internal Revenue Service. Form 1099 NEC and Independent Contractors
Forms the Business Handles
Form W-9: Collect It Before the First Payment
Ask every new contractor for a completed Form W-9 before you cut a check. The W-9 gives you the contractor’s taxpayer identification number (a Social Security Number for individuals, or an Employer Identification Number for a business) and certifies whether they’re subject to backup withholding.2Internal Revenue Service. Instructions for the Requester of Form W-9 If you wait until January to chase down W-9s, you’ll be scrambling against your filing deadline.
If a contractor refuses to hand over a W-9 or gives you an incorrect TIN, you have to withhold 24% of each payment as backup withholding and send it to the IRS.3Internal Revenue Service. 2026 Publication 15 You then report the amounts you withheld during the year on Form 945.
Form 1099-NEC: The Main Reporting Form
Form 1099-NEC is how you report payments to contractors. For payments made in 2026, you file a 1099-NEC for anyone you paid $2,000 or more during the calendar year for services in the course of your trade or business.1Internal Revenue Service. Form 1099 NEC and Independent Contractors The threshold sat at $600 for years, so update any internal cutoffs you have. It will adjust for inflation starting in 2027.
You also have to file a 1099-NEC for any contractor whose payments were subject to backup withholding, no matter how small the total.4Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (04/2025) Both the IRS copy and the contractor’s copy are due January 31 of the following year. No extensions on the contractor copy.
Foreign Contractors: W-8BEN Instead of W-9
For a contractor who is not a U.S. citizen or resident alien, collect Form W-8BEN (individuals) or Form W-8BEN-E (foreign entities) rather than a W-9. The form certifies foreign status and can establish a reduced withholding rate under a tax treaty.5Internal Revenue Service. Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals) If someone tells you they’re foreign but is actually a U.S. person, including a resident alien, they belong on a W-9.
Contractors Paid Through PayPal, Venmo, or Cards
When you pay through a third-party platform, the platform may issue Form 1099-K to the contractor. For 2026, the platform must issue a 1099-K only if total payments exceed $20,000 and the number of transactions exceeds 200.6Internal Revenue Service. Form 1099-K Frequently Asked Questions If you paid a contractor entirely through such a platform, you generally don’t also owe a 1099-NEC, because the processor handles the reporting. If you paid partly by check and partly through a platform, you may still owe a 1099-NEC for the non-platform portion.7Internal Revenue Service. What to Do with Form 1099-K
E-Filing and Penalties
If your business files 10 or more information returns of any type in a year (1099-NECs, W-2s, and everything else counted together), you have to e-file. That threshold has been in place since tax year 2024.8Internal Revenue Service. E-File Information Returns Filing on paper when you were required to e-file can cost up to $340 per return.
Late or incorrect 1099-NEC filings escalate the longer you wait:
- Corrected within 30 days of the due date: $50 per return, up to $500,000 for the year
- Corrected after 30 days but by August 1: $100 per return, up to $1,500,000
- Filed after August 1 or never filed: $250 per return, up to $3,000,000
Small businesses with gross receipts of $5,000,000 or less get lower caps: $175,000, $500,000, and $1,000,000. Intentional disregard has no cap at all.9Office of the Law Revision Counsel. 26 USC 6721 – Failure to File Correct Information Returns
Forms the Contractor Files
Schedule C: Business Income and Expenses
If you work as an independent contractor and you’re either a sole proprietor or a single-member LLC that hasn’t elected corporate tax treatment, your income and expenses go on Schedule C, attached to your Form 1040.10Internal Revenue Service. Instructions for Schedule C (Form 1040) Every 1099-NEC you receive feeds in here. Total gross receipts at the top, business expenses in the middle, net profit or loss at the bottom. That final number flows to your 1040 and drives both your income tax and your self-employment tax.
Schedule C is also where you deduct ordinary and necessary expenses: supplies, software, travel, professional development, advertising, and so on. If part of your home is used exclusively and regularly for business, you can take a home office deduction, either the simplified method (a flat rate per square foot) or the regular method on Form 8829.11Internal Revenue Service.

Schedule SE: Self-Employment Tax
Employees split Social Security and Medicare taxes with their employer. As a contractor, you pay both halves. Schedule SE calculates that combined self-employment tax at 15.3% of net earnings: 12.4% Social Security plus 2.9% Medicare.12Internal Revenue Service. Topic No. 554, Self-Employment Tax You have to file Schedule SE once your net self-employment earnings hit $400.13Internal Revenue Service. 2025 Instructions for Schedule SE (Form 1040)
The 12.4% Social Security portion only applies to earnings up to $184,500 in 2026.14Social Security Administration. Contribution and Benefit Base Anything above that ceiling still owes the 2.9% Medicare piece, which has no upper limit. You do get to deduct half of your self-employment tax as an adjustment to income on your 1040.
Form 8959: Additional Medicare Tax
If self-employment income exceeds $200,000 (or $250,000 married filing jointly), you owe an extra 0.9% Additional Medicare Tax on the excess, calculated on Form 8959 and attached to your return.15Internal Revenue Service. Topic No. 560, Additional Medicare Tax No portion of this one is deductible.
Form 1040-ES: Quarterly Estimated Payments
Nobody’s withholding tax from your contractor income, so you’re expected to pay as you go with Form 1040-ES. You owe estimated payments if you expect to owe $1,000 or more in tax for the year after subtracting withholding and refundable credits.16Internal Revenue Service. 2026 Form 1040-ES, Estimated Tax for Individuals The 2026 due dates:
- 1st quarter: April 15, 2026
- 2nd quarter: June 15, 2026
- 3rd quarter: September 15, 2026
- 4th quarter: January 15, 2027
You can skip the January 15 payment if you file your 2026 return and pay the full balance by February 1, 2027.
To avoid underpayment penalties, your total payments for the year need to cover at least the smaller of 90% of your current-year tax or 100% of your prior-year tax. If last year’s adjusted gross income was above $150,000 ($75,000 if married filing separately), the prior-year safe harbor rises to 110%.17Internal Revenue Service. Estimated Tax In your first contractor year, the 90% current-year rule is the one to hit.
Form 7206: Self-Employed Health Insurance Deduction
Contractors who pay their own health insurance often miss this one. If you have a net profit on Schedule C and aren’t eligible for coverage through a spouse’s employer plan, you can deduct health, dental, and vision premiums as an adjustment to income rather than as an itemized deduction. Coverage counts for you, your spouse, dependents, and any child under age 27 (even if not your dependent). The calculation lives on Form 7206.18Internal Revenue Service. Instructions for Form 7206 For any month you were eligible to join an employer-subsidized plan, no deduction.
Get Classification Right Before You File Anything
None of these forms are the right forms if the worker isn’t actually a contractor. The IRS looks at behavioral control, financial control, and the type of relationship, weighed together, to decide whether someone is an employee or an independent contractor.19Internal Revenue Service. Employee (Common-Law Employee) If you’re unsure, either side can file Form SS-8 to ask the IRS for a formal determination.20Internal Revenue Service. About Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding
Getting it wrong is expensive. If the IRS decides your “contractor” was really an employee, your business is on the hook for the income tax withholding, Social Security and Medicare, and unemployment taxes you should have been paying all along.21Internal Revenue Service. Worker Classification 101: Employee or Independent Contractor The Department of Labor can also pursue unpaid minimum wage and overtime under the Fair Labor Standards Act.22U.S. Department of Labor. Misclassification of Employees as Independent Contractors Under the Fair Labor Standards Act
