The short answer
Whether a worker is an employee or an independent contractor depends on the whole relationship, mainly how much control you have over the work, not on what you call the person or which form you issue. The IRS, the Idaho Department of Labor and the U.S. Department of Labor each apply their own test. The answer changes payroll, tax forms and records, so the decision generally belongs with a CPA or an employment attorney.
Why the label does not decide it
It usually starts small. You bring in a helper for a busy season, pay them through an app, and plan to send a 1099 in January. A year later the helper works set hours, uses your tools and answers to you every day. On paper they are a contractor. The facts may say otherwise.
The IRS says all information that shows the degree of control and independence must be considered. The Idaho Department of Labor is blunter: issuing an IRS Form 1099 or paying on commission only does not make someone an independent contractor, and a written or verbal contract alone does not establish it. The actual working relationship decides.
This guide compares the two paths and the records each one creates. It does not classify anyone. That call carries back taxes and penalties if it is wrong, so it belongs with a CPA or employment attorney working from the facts. For the contractor paperwork itself (the W-9, the 2026 reporting threshold and the January deadline), see paying contractors: the records to have before January.
The IRS test: control and independence
For federal employment taxes, the IRS uses the common-law rules. It groups the evidence into three categories and says to weigh all of them. No set number of factors makes someone an employee or a contractor, and no single factor decides it.
- Behavioral: does the business control, or have the right to control, what the worker does and how they do it?
- Financial: does the business control the business side of the work, such as how the worker is paid, whether expenses are reimbursed, and who provides tools and supplies?
- Type of relationship: is there a written contract or employee-type benefits, will the relationship continue, and is the work a key part of the business?
When the answer is unclear: Form SS-8
The IRS also says to document each factor used to reach the decision. It adds that a remote worker is still an employee under the common-law rules if you can control what will be done and how.
If the answer is still unclear, either the business or the worker can file Form SS-8, Determination of Worker Status. The IRS reviews the facts and makes an official determination, and it warns that a determination may take at least six months. Your CPA or attorney can tell you whether filing one makes sense for your situation.
Idaho unemployment insurance and the federal wage-and-hour test
Idaho applies its own test for unemployment insurance. The Idaho Department of Labor's tax handbook for businesses says a worker is an independent contractor, exempt from unemployment insurance tax, only if both conditions are met: the worker is free from direction and control in performing the work, and the worker is engaged in an independently established trade, occupation, profession or business, citing Idaho Code section 72-1316(4). The handbook points businesses with questions to their local tax representative.
Minimum wage and overtime follow a third test. The federal Fair Labor Standards Act looks at the economic reality of the relationship, and the rule that explains it is in flux. A 2024 Department of Labor rule is still in the Code of Federal Regulations at 29 CFR part 795. The Department has said it is no longer applying that rule's analysis in its investigations. On February 27, 2026, it published a proposed rule in the Federal Register to rescind the 2024 rule and return to its 2021 analysis, with some changes. Comments closed April 28, 2026. As of November 8, 2026, no final rule had been published. Your employment attorney can tell you where it stands when you decide.
| Record or task | Employee | Independent contractor |
|---|---|---|
| Form collected at the start | Form I-9 for work eligibility and Form W-4 for withholding | Form W-9 with the legal name and taxpayer ID |
| How pay is recorded | Wages through payroll, with withholding and employer taxes recorded | Vendor payments against invoices, generally with no withholding |
| Year-end form | Form W-2 | Form 1099-NEC if payments reach the threshold; see contractor records |
| Idaho unemployment insurance | Wages reported for the quarter they are paid | Exempt only if free from direction and control and independently established |
| Federal records to keep | Employment tax records for at least four years | The W-9 for four years, plus invoices and payment records |
The paperwork each path creates
Once the call is made, the books follow it. Most of the work is collecting the right form at the start and recording pay the right way.
- Employee: a Form I-9 for work eligibility (the IRS says all U.S. employers must complete one for every person they hire), a signed Form W-4 for withholding, the new-hire report the Idaho Department of Labor asks for, payroll records for every pay period, and a Form W-2 after year end. Idaho payroll accounts are covered in Idaho payroll withholding basics.
- Independent contractor: a Form W-9 before the first payment (the IRS suggests keeping it for four years), the agreement or scope, each invoice, and proof of each payment with its method. A Form 1099-NEC follows if payments reach the reporting threshold.
What a bookkeeper does, and what happens if the call was wrong
The IRS says that if you treat an employee as a contractor without a reasonable basis, you may be held liable for employment taxes for that worker. It describes relief provisions for businesses that had a reasonable basis and filed consistent information returns, and a Voluntary Classification Settlement Program, applied for on Form 8952, for businesses that want to reclassify workers as employees going forward. Which of those applies is a question for your CPA or attorney.
A bookkeeper's part is to record pay the way the classification was decided and to keep the file complete. Good books also make patterns visible. A "contractor" paid the same amount every week for a year, or one who appears on the payroll and the vendor list at once, is worth raising with your adviser. Owners of an S corporation have a related question about their own pay, covered in LLC vs. S corp bookkeeping. Recording contractor payments and keeping vendor records tidy is part of small business bookkeeping, and where the firm's work stops is set out on how we work.
