1099 vs W2: The Real Cost to Both Sides, Worked Out

Most comparisons of 1099 vs W2 read like a menu. Contractor if you want it cheap and flexible, employee if you want commitment. That framing is what gets small businesses into trouble, because the label is not yours to pick. It follows from how the work is actually done.

The money still matters, and it moves in a way most guides never show.

Below, the same $50,000 of pay is worked through both ways, for the business and for the worker, at 2026 federal rates. Then come the questions Google gets asked most: what a W-9 is, what happened to the $600 rule, and what it costs to get the label wrong.

1099 vs W2 at a Glance

The table comes from the IRS page on contractors and employees, which puts the employer's side in two sentences. For an employee you withhold income tax, Social Security and Medicare, pay the matching employer share, and pay unemployment tax. For an independent contractor you generally do not withhold or pay any taxes at all.

That second sentence is why the label is tempting, and why the IRS checks it. Every line in the right-hand column is a cost the business no longer carries. Someone still pays most of it.

Who Decides Whether Someone Is 1099 or W-2

The relationship decides, not the paperwork. The IRS groups the evidence into three categories under the common law rules:

• Behavioral control. Do you control, or have the right to control, what the worker does and how they do it?
• Financial control. Do you control the business side of the job: how they are paid, whether expenses are reimbursed, who supplies the tools?
• Type of relationship. Is there a written contract or employee-type benefits? Will the work continue, and is it a key part of your business?

The IRS is explicit that there is no magic number of factors and that no single factor decides it. You weigh the whole relationship, and you are told to document how you reached the answer. In practice, three questions do most of the sorting:

Working remotely does not change the answer. The IRS says a remote worker is your employee if you can control what will be done and how, even if they chose to work from home.

This is the trap with an assistant who works set hours on your tasks, your tools and your instructions. Our guide to hiring a virtual assistant walks through that case.

Two other tests sit alongside the IRS one:

• The Department of Labor. For minimum wage and overtime, the DOL asks whether the worker is economically dependent on you or in business for themselves. It proposed a new version of that test on February 26, 2026, built around two core factors: control over the work and the chance of profit or loss.
• Your state. Some states are stricter. California's ABC test treats a worker as an employee unless all three conditions hold, including that the work is outside the usual course of your business.

If you are still unsure, either side can file Form SS-8 and the IRS will decide. Plan for the wait: the IRS says a determination can take at least six months.

1099 vs W2 Taxes: Who Pays What in 2026

The tax difference is mostly about Social Security and Medicare. An employee splits it with you. A contractor pays both halves alone, as self-employment tax.

The sources for each line:

• Social Security and Medicare. The Social Security Administration sets the employee and employer rates at 6.2% each for Social Security and 1.45% each for Medicare. Social Security stops at $184,500 of earnings in 2026. Medicare has no cap.
• Self-employment tax. The IRS puts it at 15.3%, which is 12.4% plus 2.9%. It applies to 92.35% of net earnings, and the contractor can deduct the employer-equivalent half when working out their income tax.
• Federal unemployment. The FUTA rate is 6.0% on the first $7,000 of each employee's wages, and a credit of up to 5.4% for paying state unemployment brings it to 0.6%.
• Estimated tax. A contractor generally has to make quarterly estimated payments once they expect to owe $1,000 or more for the year. Nobody withholds for them.

State unemployment tax and workers' compensation insurance come on top for an employee. Both vary by state, so they are left out of the federal numbers below.

Worked Example: $50,000 Paid Both Ways

Take one person paid $50,000 for a year of work, with no business expenses, at 2026 rates. Here is where the money goes under each label.

For the business. On a W-2 you pay $3,100 of Social Security, $725 of Medicare and $42 of federal unemployment, so the year costs $53,867 before state taxes and insurance. On a 1099 it costs $50,000 and one Form 1099-NEC.

For the worker. On a W-2, $3,825 comes out of their pay for Social Security and Medicare. On a 1099 they owe $7,065 of self-employment tax on the same $50,000, which is $3,240 more.

They can deduct half of it, $3,532, when working out their income tax, which softens the gap but does not close it.

The rate that breaks even. To keep the same $46,175 after Social Security and Medicare, the contractor needs to bill $53,773, which is 7.5% more. A $40 an hour employee job equals about $43 an hour on a 1099, before anything else.

Benefits are the larger gap. In June 2026, benefits made up 30.0% of private employers' compensation costs, according to the Bureau of Labor Statistics. That figure includes the legally required payroll taxes above, plus paid leave, insurance and retirement. A contractor pays for every one of those themselves.

1099 or W-2: Which Is Better?

It depends which side you are on, and only one side really gets a choice.

For the business, it is not a preference. Once you control the work, the person is an employee, and the cheaper label is not available. Where the work genuinely is a contractor's, a 1099 is simpler: no payroll, no withholding, one form a year.

For the worker, it is a real trade. A 1099 tends to suit someone who:

• has several clients, so losing one is not losing everything,
• can bill well above the 7.5% break-even,
• has real business expenses to deduct, which an employee cannot, and
• may qualify for the qualified business income deduction of up to 20%.

A W-2 tends to suit someone who wants the other half of Social Security and Medicare paid for them, tax withheld automatically, unemployment cover, and minimum wage and overtime protection. The deductions a contractor can claim are covered in our small business tax deductions guide.

What Is a W-9?

Form W-9 is how a contractor gives you their taxpayer identification number before you pay them. The IRS describes it as the form used to give your correct TIN to someone who has to file an information return, such as a 1099, about income paid to you.

You need it because you cannot file the 1099-NEC without that number. Collect it before the first payment, not in January. On the W-9 a sole proprietor can give either a Social Security number or an EIN, and EIN vs SSN explains which to use. A W-2 employee fills in a Form W-4 instead.

What Is the $600 Rule for 1099?

It was the old threshold, and it is now $2,000. For years, a business had to file a Form 1099-NEC for any contractor it paid $600 or more in a year. For tax years beginning after 2025, the IRS instructions raise that minimum to $2,000, adjusted for inflation from 2027.

So for work paid in 2026, you file a 1099-NEC for each contractor you paid $2,000 or more. It is due to the IRS by January 31, and the contractor gets their copy too.

The $600 figure still turns up in older guides and in one corner of the rules: the same instructions keep $600 for gross proceeds paid to an attorney.

Filing late is priced per form. For returns due in 2027, the IRS penalty is $60 per form up to 30 days late, $130 up to August 1, $340 after that or if never filed, and $690 for intentional disregard.

Is It Illegal to 1099 a Full-Time Employee?

If they are an employee in fact, yes. Treating them as a contractor breaks federal tax law and usually labor law too.

Hours alone do not decide it, though. A contractor can work 40 hours a week on one project. What makes someone an employee is the control described above, and full-time, open-ended work on your instructions is the classic pattern of it.

The label is not a defense. The Department of Labor says employers are responsible for getting it right, and that misclassified employees may miss out on minimum wage, overtime and other protections they are owed.

A signed contractor agreement helps only when it matches how the work really runs. Our freelance contract template is written for genuine contractor work, not as cover for an employee.

The Penalty for Paying Someone on a 1099 Instead of a W-2

If you classify an employee as a contractor without a reasonable basis, the IRS can hold you liable for that worker's employment taxes. For mistakes that were not intentional, section 3509 of the tax code sets the bill.

Here is what that means for the same $50,000 worker, for one year:

Under section 3509 you also cannot recover any of that tax from the worker. The reduced rates do not apply at all if the IRS finds intentional disregard, and then the full amounts are owed.

Federal tax is also only one bill. The Department of Labor can pursue unpaid overtime, and your state can pursue unemployment contributions.

There are two ways back:

• Section 530 relief. If you had a reasonable basis, filed every required 1099 consistently and never treated someone in a similar role as an employee, you may be relieved of the employment taxes.
• The Voluntary Classification Settlement Program. If you reclassify the worker as an employee going forward, the VCSP lets you pay 10% of one year's liability at the section 3509 rates, with no interest or penalties. For our $50,000 worker that is $534 instead of $5,340. You need three years of filed 1099s for that worker, no employment tax audit under way, and an application at least 120 days before the switch.

A worker who thinks they were misclassified can file Form 8919 with their own return to pay only the employee share of Social Security and Medicare. That tells the IRS the worker considers themselves an employee, whether the business raises it or not.

Five Classification Mistakes That Cost Small Businesses

1. Choosing the label on price. The $3,867 a 1099 saves you on a $50,000 worker is real only if the person genuinely is a contractor.
2. Trusting the contract over the work. The IRS and the DOL look at what actually happens. A contract that says "independent contractor" changes nothing if you set the hours.
3. Collecting the W-9 late. Chasing tax numbers in January is how 1099s get filed after the deadline at $60 to $340 a form.
4. Using the old $600 threshold, or no threshold. For 2026 payments the line is $2,000, and it is a total for the year, not a limit per invoice.
5. Letting a contractor drift into an employee. A defined project becomes open-ended, then comes with set hours and your tools. Re-ask the three questions whenever the work changes.
