Employee or contractor? Why the difference matters

In the trades especially, “I’ll just 1099 him” is said as if it were a decision the business gets to make. It is not. Whether someone is an employee or an independent contractor is a question of fact about how the work actually happens, and the label on the invoice does not change the answer.

The three things the IRS looks at

The IRS groups the evidence into three categories.

• Behavioural control. Does the business control, or have the right to control, what the worker does and how the job is done? Set hours, required methods, training in how to do the work, and close supervision all point towards employment.
• Financial control. Who controls the business side of the job? How the worker is paid, whether expenses are reimbursed, and who supplies the tools and materials. A worker who invests in their own equipment, can make a profit or a loss, and offers the same services to other businesses looks more like a contractor.
• Type of relationship. Are there written contracts? Are there employee-type benefits such as insurance, a pension or paid time off? Is the relationship expected to continue indefinitely? Is the work a key part of the regular business?

The IRS is explicit that there is no “magic” or set number of factors that makes someone an employee or a contractor, and that no one factor stands alone. The whole relationship is weighed together, and the business is expected to document how it reached its conclusion.

Why a written contract is not enough

A contract that calls someone an independent contractor is one piece of evidence under “type of relationship.” It does not outweigh the other two categories. A worker who signs a contractor agreement, then works set hours on the business’s schedule, using the business’s tools, under its supervision, on work central to what the business does, is being treated as an employee in every way that counts.

What goes wrong when the classification is wrong

If a business treats an employee as an independent contractor and has no reasonable basis for doing so, the IRS says it may be held liable for the employment taxes for that worker. In practice that means the taxes that should have been withheld and paid, going back over the period in question, and it arrives as one bill rather than as the small deductions it would have been.

There are relief provisions for businesses that had a reasonable basis for contractor treatment, but they have conditions: the business must have filed all required information returns consistently with that treatment, and must not have treated any worker in a substantially similar position as an employee. The IRS also runs a voluntary programme that lets a business reclassify workers as employees for future periods with partial relief on past employment taxes. Both are worth knowing about; neither is a substitute for getting it right from the start.

What the difference changes day to day

For an employee, the business withholds income tax and the employee’s share of Social Security and Medicare, pays the employer’s share, files employment tax returns, and issues a W-2.

For a genuine independent contractor, the business pays the invoice and, where payments cross the IRS reporting threshold for the year, issues a 1099 form. The contractor handles their own taxes.

The second arrangement is cheaper and simpler for the business, which is exactly why the IRS checks that it is real.

If you are genuinely not sure

Either the business or the worker can ask the IRS to decide, using Form SS-8. The IRS notes that it may take at least six months to receive a determination, so this is not a quick fix for a hire you need to make next week. For most small businesses the practical path is to look honestly at the three categories above, write down the reasoning, and get advice before the first payment rather than after a year of them.

A short test to apply before you hire

1. Will the business set the hours and the method, or only the result?
2. Who supplies the tools, the vehicle and the materials?
3. Does this person do the same work for other businesses, and could they make a loss on this job?
4. Is the role ongoing and central to the business, or a defined piece of work with an end?

If the answers lean towards control, the business’s tools, exclusivity and permanence, the honest classification is probably employee, whatever the paperwork says.
