The form you file depends entirely on the worker's classification. Employees get a W-2. Independent contractors get a 1099-NEC. The IRS uses three categories to make the call: behavioral control, financial control, and the type of relationship.
The label you put on a worker does not determine their status. The IRS looks at the actual working relationship. A written contract that calls someone a contractor, or a 1099-NEC you issued, does not make them one if the facts say otherwise.
Get it wrong and the consequences follow the employer, not the worker. You can owe back employment taxes, penalties, and interest on every misclassified worker going back years.
Misclassifying an employee as an independent contractor without a reasonable basis can result in liability for income tax withholding, Social Security, Medicare, and federal unemployment taxes for that worker, plus penalties and interest.
The IRS uses what it calls the common law rules to determine worker classification. Three categories of evidence apply. No single factor is decisive. You look at all of them together.
Behavioral control. Does your business control or have the right to control what the worker does and how they do it? This includes the type and degree of instruction you give, whether you provide training, and whether work is evaluated on process or only on results.
Financial control. Does your business control the financial and business aspects of the worker's job? This covers how the worker is paid, whether they have their own unreimbursed expenses, whether they invest in their own equipment, and whether they are free to offer their services to the general public.
Type of relationship. How do the worker and business perceive their relationship? Written contracts, employee benefits, the permanency of the relationship, and whether the work performed is a key part of the business's regular operations all factor in.
No single row in this table determines classification. Look at the full picture.
| Factor | Points toward employee (W-2) | Points toward contractor (1099-NEC) |
|---|---|---|
| Instructions | You tell the worker when, where, and how to do the work | Worker controls their own methods; you define only the result |
| Training | You train the worker on your procedures and methods | Worker brings their own established skills; no training needed |
| Equipment | You supply tools, equipment, or workspace | Worker invests in their own tools and workspace |
| Payment method | Regular wages or salary on a set schedule | Flat fee or per-project payment; worker submits invoices |
| Other clients | Worker serves only your business | Worker offers services to the public and has multiple clients |
| Benefits | You provide insurance, vacation pay, retirement plan, or other benefits | No benefits; worker covers their own |
| Length of relationship | Ongoing, indefinite relationship | Defined project or time-limited engagement |
| Business integration | Work is a core part of your regular business operations | Work is a discrete, specialized service outside your core operations |
No. A written agreement stating that a worker is an independent contractor is a factor the IRS considers, but it is not controlling. If the actual day-to-day relationship looks like employment, the IRS will classify the worker as an employee regardless of what the contract says.
A contractor agreement does help document intent and can support a reasonable basis defense if classification is ever challenged. Use one, but do not rely on it alone.
Location does not change the test. A worker performing services for you from a home office or another remote location is still your employee under the common law rules if you control what they do and how they do it. The right to control is what matters, not where the work happens.
The tax obligations are different depending on classification.
For employees (W-2): You withhold federal income tax, Social Security tax (6.2%), and Medicare tax (1.45%) from each paycheck. You also pay the employer's matching share of Social Security and Medicare, plus federal unemployment tax (FUTA). You file Form W-2 for each employee and Form W-3 as a transmittal.
For independent contractors (1099-NEC): You do not withhold any taxes. You do not pay the employer share of Social Security or Medicare. You do not pay FUTA. You file Form 1099-NEC for each contractor you paid at or above the reporting threshold for the year.
Contractors pay their own self-employment tax, which covers both the employer and employee share of Social Security and Medicare. That is their responsibility, not yours.
If you misclassify an employee as a contractor without a reasonable basis, you may owe the full amount of employment taxes that should have been withheld and paid, plus interest and penalties.
The IRS uses Internal Revenue Code Section 3509 to set reduced liability rates when misclassification was unintentional and you filed 1099-NEC forms consistently. Under Section 3509, you owe 1.5% of wages for income tax withholding and 20% of the employee share of FICA taxes, plus the full employer match. If you did not file 1099s, those rates double.
Willful misclassification removes the reduced rates entirely. You owe the full amount of all taxes that should have been withheld, including income, Social Security, and Medicare taxes.
File Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding. Either you or the worker can file it. The IRS will review the facts and issue an official determination. Allow at least six months for a response.
If you have already misclassified workers and want to correct it going forward, the Voluntary Classification Settlement Program (VCSP) lets you reclassify contractors as employees for future tax periods with significantly reduced back-tax liability. You pay roughly 1% of the wages paid to the affected workers for the most recent year. Apply with Form 8952 at least 60 days before the date you want to start treating them as employees.
To qualify for VCSP, you must have consistently treated the workers as contractors, filed all required 1099-NEC forms for the prior three years, and not be currently under an employment tax audit.
Once you have determined a worker is an independent contractor, use Adams® Tax Forms Helper® to prepare and eFile Form 1099-NEC. For employees, use Tax Forms Helper to prepare and eFile Form W-2 with the Social Security Administration.

The common law rules, which weigh three categories of evidence: behavioral control, meaning whether you control what the worker does and how they do it; financial control, meaning how they are paid, whose equipment they use, and whether they can offer services to the public; and the type of relationship, covering contracts, benefits, permanency, and whether the work is core to your business. No single factor is decisive.
No. A written agreement is a factor the IRS considers, but it is not controlling. If the day-to-day relationship looks like employment, the IRS will classify the worker as an employee regardless of what the contract says. A contractor agreement still helps document intent and can support a reasonable basis defense, so use one, but do not rely on it alone.
No. Location does not change the test. A worker performing services from a home office or another remote location is still your employee under the common law rules if you control what they do and how they do it. The right to control is what matters, not where the work happens.
Without a reasonable basis you may owe the full employment taxes that should have been withheld and paid, plus interest and penalties. IRC Section 3509 sets reduced rates when misclassification was unintentional and you filed 1099-NEC forms consistently: 1.5 percent of wages for income tax withholding and 20 percent of the employee FICA share, plus the full employer match, with those rates doubling if you filed no 1099s. Willful misclassification removes the reduced rates entirely.

Reduce the 250-return threshold enacted in prior regulations to generally require electronic filing by filers of 10 or more returns in a calendar year. The final regulations also create several new regulations to require e-filing of certain returns and other documents not previously required to be e-filed.
Require filers to aggregate almost all information return types covered by the regulation to determine whether a filer meets the 10-return threshold and is required to e-file their information returns. Earlier regulations applied the 250-return threshold separately to each type of information return covered by the regulations.
Eliminate the e-filing exception for income tax returns of corporations that report total assets under $10 million at the end of their taxable year, and require partnerships with more than 100 partners to e-file information returns, and they require partnerships required to file at least 10 returns of any type during the calendar year to e-file their partnership return.
Corrections must be filed the same way the original was submitted. If you eFile the original then you must eFile the correction. If you mailed in the original then you must mail in the correction.
Do not cut or separate Copies A of the forms that are printed two or three to a sheet, except for Form W-2G. Generally, Forms 1097, 1098, 1099, 3921, 3922, and 5498 are printed two or three to an 8" x 11"sheet. Form 1096 is printed one to an 8" x 11" sheet.
These forms must be submitted to the IRS on the 8" x 11" sheet. If at least one form on the page is completed, you must submit the entire page. Forms W-2G are an exception and may be separated and submitted as single forms. Send your forms to the IRS in a flat mailing (not folded).
Do not staple, tear, or tape any of these forms. It will interfere with the IRS’s ability to scan the documents.
Pinfeed holes on the form are not acceptable. Pinfeed strips outside the 8" x 11" area must be removed before submission without tearing or ripping the form. Substitute forms prepared on continuous feed or strip form paper must be burst and stripped to conform to the size specified for a single sheet (8" x 11") before they are filed with the IRS.
Do not use a form to report information that is not properly reportable on that form. If you are unsure of where to report the data, call the information reporting customer service site at 1-866-455-7438 (toll free).
Do not submit anything other than red ink copies to the IRS.
Use the official forms or substitute forms that meet the specifications in Pub. 1179. If you submit substitute forms that do not meet the current specifications and that are not scannable, you may be subject to a penalty for each return for improper format. All of Adam’s tax forms meet the proper requirements, so use us as a resource.
Do not use dollar signs ($) (they are pre-printed on the forms), ampersands (&), asterisks (*), commas (,), or other special characters in money amount boxes.
Do not use apostrophes (’), asterisks (*), or other special characters on the payee name line.
No photocopies of any form are acceptable.
Do not print plain ink copies of your W-2 copy A or W-3 form. If a box doesn't apply to you, leave it empty.
Do not add "0".
Do not omit the decimal point and cents from entries.
Do not mistakenly check the “Retirement plan” checkbox in box 13. See page 22 of this IRS PDF for Retirement plan details.
Do not misformat the employee’s name in box e. Enter the employee’s first name and middle initial in the first box; his or her surname in the second box; and his or her suffix (such as “Jr.”) in the third box (optional).
Do not enter the incorrect employer identification number (EIN) or the employee’s SSN for the EIN.
Do not cut, fold or staple Copy A paper forms mailed to SSA.
Do not mail any copy other than Copy A of Form W2 to the SSA.
File the correct form with the correct amount, code, checkbox, name or address, and check the “CORRECTED” box. This overwrites what you originally filed with the IRS under that person or company’s name and TIN. Send the corrected form to the recipient and prepare the red Copy A to send to the IRS with the Form 1096 transmittal if you’re paper filing. If you also had the wrong recipient/payee name or TIN do a Type 2 correction instead.
For Type 2 errors, either the recipient/payee name and/or the TIN are wrong or you used the wrong form (like a 1099-MISC instead of a 1099-NEC). Action: This is a two-step process. First, you must zero out what you filed with the IRS under the wrong name/TIN and then file the new form.
Step 1
File a form with the CORRECTED box checked and the exact same payer and recipient information as on the incorrect form, but with all the amounts as zeros. This will remove the originally filed form from the IRS records.
Step 2
File a new Form 1099 with the right information as an originally filed form (not a corrected form).
Incorrect Payer Name, Payer TIN, or both Action: Write a letter to the IRS.
If you filed with the wrong payer name (yours or your client’s name/company name) or the wrong payer taxpayer identification number (TIN), you don’t need to send in a corrected form.
Instead, you should write a letter containing the following information:
Name and address of the payer
Type of error (including the incorrect payer name/TIN that was reported)
Tax year Payer TIN Transmitter Control Code (if you eFiled),
Type of return, Number of payees, Filing method (paper or eFiling)
You have exceeded the IRS paper filing threshold and are required to file electronically.
