To hire a 1099 contractor, confirm the person really qualifies as an independent contractor under federal and state tests, get a signed Form W-9 before any money changes hands, sign a written agreement that spells out scope and ownership, pay without withholding income or payroll taxes, and file Form 1099-NEC after year-end if you paid the contractor $2,000 or more for services. Each step protects you from a different risk, and skipping any one of them is where most problems start.
Confirm the Worker Really Is a Contractor
Classification is the first decision, not a label you get to choose. The IRS, the Department of Labor, and many states each apply their own test, and a worker can come out an employee under one test and a contractor under another. If any agency later disagrees with your call, you owe the back taxes and penalties, not the worker.
The IRS looks at the overall relationship in three buckets: behavioral control (do you direct when, where, and how the work gets done), financial control (does the worker invest in their own tools, serve other clients, and stand to profit or lose money), and the type of relationship (written contract, benefits, whether the work is core to your business). No single factor decides it. The question is whether your business has the right to control the details of the work, even if you don’t actually exercise that control day to day.1Internal Revenue Service. Independent Contractor (Self-Employed) or Employee? If you can’t tell, you or the worker can file Form SS-8 and ask the IRS for a written determination.2Internal Revenue Service. Instructions for Form SS-8
The Department of Labor uses a different framework under the Fair Labor Standards Act. Its current rule, effective March 11, 2024, asks whether the worker is economically dependent on your business or truly running their own. A worker who relies on your company for their livelihood will be treated as an employee for minimum wage and overtime purposes, even if the contract says otherwise.3U.S. Department of Labor. Fact Sheet 13 – Employee or Independent Contractor Classification Under the Fair Labor Standards Act (FLSA)4Federal Register. Employee or Independent Contractor Classification Under the Fair Labor Standards Act
A number of states apply a stricter ABC test, usually for unemployment tax and sometimes broader labor purposes. Under it, a worker is presumed to be an employee unless the business proves all three: the worker is free from company control over how the work is done, the work falls outside the company’s usual business, and the worker has an independently established trade or business of the same type. Failing any single prong makes the worker an employee. Check the rules in every state where your contractors actually perform work, because the state answer can differ from the federal one.
What Misclassification Costs
If the IRS or DOL reclassifies a contractor as an employee, you become liable for employment taxes you never withheld. The employer’s share of Social Security and Medicare alone is 7.65 percent of wages paid,5Internal Revenue Service. FICA Tip Credit for Employers and on top of that you can owe the worker’s share, federal income tax withholding, and penalties and interest going back years.
Federal law reduces those amounts when the misclassification wasn’t intentional and you actually filed 1099s: income tax withholding liability drops to 1.5 percent of wages, and the employee-side Social Security and Medicare liability drops to 20 percent of what would otherwise be owed. Skip the 1099s and both figures double, to 3 percent and 40 percent.6Office of the Law Revision Counsel. 26 U.S. Code 3509 – Determination of Employer’s Liability for Certain Employment Taxes The DOL can separately pursue back overtime and minimum wage under the FLSA, and state agencies can chase unpaid unemployment insurance and workers’ compensation premiums. The costs stack fast across multiple workers and multiple years.
Get a Signed W-9 Before Any Work Begins
Before the contractor starts, have them complete IRS Form W-9. The form captures their legal name, entity type, address, and Taxpayer Identification Number (a Social Security Number for individuals, an EIN for a business), and the contractor signs under penalty of perjury that the information is correct.7Internal Revenue Service. Form W-9 (Rev. March 2024) – Request for Taxpayer Identification Number and Certification Getting the W-9 up front prevents scrambling at year-end when you need to file a 1099 and can’t reach the contractor.
If the contractor refuses to give you a TIN, provides an obviously wrong one, or won’t certify they aren’t subject to backup withholding, you have to withhold 24 percent of every payment and send it to the IRS.8Internal Revenue Service. Topic No. 307 – Backup Withholding You may also receive a CP2100 notice after filing 1099s if the name and TIN you reported don’t match IRS records; when that arrives, compare it against your files, correct any errors, and start backup withholding on future payments if the mismatch isn’t resolved. Backup withholding gets reported on Form 945, due January 31 of the following year.
Put the Engagement in Writing
A written agreement protects both sides and, done right, reinforces the contractor classification. At a minimum, the contract should cover the scope of work and deliverables, the payment structure (flat fee, hourly, or milestone-based) and invoicing terms, the start and end dates, how either side can terminate, and an indemnification clause putting responsibility for the contractor’s own negligence or legal violations on them. Confirm in the document that the contractor handles their own taxes, insurance, and business expenses.
Avoid contract language that makes the arrangement look like employment: mandatory set schedules, exclusivity requirements, or company training unrelated to the specific project all cut against contractor status.
Assign the Intellectual Property in Writing
Under federal copyright law, work created by an independent contractor is not automatically owned by the business that paid for it. A “work made for hire” by a non-employee qualifies only if it falls into one of nine narrow statutory categories (contributions to a collective work, translations, compilations, and a handful of others) and only if both parties sign a written agreement designating it as such.9Office of the Law Revision Counsel. 17 U.S. Code 101 – Definitions Custom software, marketing copy, branding, and business plans typically don’t fit those categories.
To actually own the work, include a present-tense assignment clause that transfers all intellectual property rights to your business at the moment of creation. Without it, the contractor keeps ownership and can reuse, license, or sell the same work to your competitors.
Pay the Contractor and Keep the Records
Set the contractor up as a vendor in your accounting system using the exact name, TIN, entity type, and address from the W-9. Pay the invoiced amounts in full; do not withhold federal income tax or Social Security and Medicare from a contractor’s payments. Withholding those items is one of the clearest signals of an employment relationship. The only exception is the 24 percent backup withholding described above, and it’s triggered by the contractor’s paperwork problem, not yours.
Keep the signed agreement, the W-9, any certificates of insurance, and any professional licenses on file, digital or physical. The IRS requires employment tax records to be kept for at least four years after the tax becomes due or is paid, whichever is later,10Internal Revenue Service. Employment Tax Recordkeeping and keeping contractor records for the same window protects you if a classification or 1099 accuracy question comes up later. For higher-risk work such as construction, on-site services, or projects involving sensitive data, ask for a certificate of insurance showing the contractor’s general liability coverage and consider requiring your business to be named as an additional insured.
File Form 1099-NEC After Year-End
For payments made in 2026, file Form 1099-NEC (Nonemployee Compensation) for any contractor you paid $2,000 or more during the calendar year for services performed in the course of your business.11Internal Revenue Service. Form 1099 NEC and Independent Contractors The threshold rose from $600 under the One Big Beautiful Bill Act, effective for payments made after December 31, 2025. Report the total gross amount paid, before any deductions. Both the IRS filing and the copy to the contractor are due January 31 of the following year.
If you file 10 or more information returns of any type in a year (1099s, W-2s, and similar forms combined), you must file them electronically through the IRS FIRE system or an approved provider.12Internal Revenue Service. E-File Information Returns
Penalties for 2026 returns scale with how late you are: $60 per form up to 30 days late, $130 per form from 31 days late through August 1, $340 per form after August 1 or if never filed, and $680 per form with no maximum cap for intentional disregard.13Internal Revenue Service. Information Return Penalties Those amounts apply separately to the IRS filing and to the copy furnished to the contractor, so one missed form can generate two penalties.
Not every payment goes on a 1099-NEC. Services always do. Rent, royalties, prizes, and legal settlement payments go on Form 1099-MISC, each with its own threshold. Payments run through a third-party settlement platform like PayPal or a credit card processor are typically reported on Form 1099-K by the platform, but confirm that rather than assume the obligation transferred.
Check State Reporting Rules
Many states require businesses to report newly engaged independent contractors to a state directory, similar to new-hire reporting for employees. Where required, reports are typically due within 20 days of the contract start or of payments reaching a set threshold,14HHS.gov. State New Hire Reporting and the data is used mainly for child support enforcement. Some states also require a state-level filing that mirrors the federal 1099-NEC, often with the same January 31 deadline. Not every state has these rules, and thresholds vary where they exist, so check with the department of revenue or labor agency in each state where your contractors perform work.
One boundary worth naming: self-employment tax is the contractor’s obligation, not yours. Contractors owe 15.3 percent on their net earnings and make their own quarterly estimated payments.15Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Your responsibility ends at paying the invoice, keeping the records, and filing the 1099.
