1099 vs W-2 Taxes: What Actually Changes

Same money, same federal income tax brackets, same standard deduction. The differences between a 1099 and a W-2 are three: you pay both halves of payroll tax instead of one, nobody withholds anything for you, and you can deduct business expenses that an employee cannot. The first difference costs roughly 7.65% of your net profit. The second is what turns an April surprise into a crisis. The third gives some of the money back, and how much depends entirely on whether you keep records.

The difference that costs real money

Social Security and Medicare tax is 15.3% — 12.4% for Social Security plus 2.9% for Medicare. On a W-2, you pay half (7.65%) and your employer pays the other half. It never appears on your payslip because it is not your money to begin with.

On a 1099, both halves are yours. That is self-employment tax, charged on 92.35% of net self-employment earnings, which makes the effective rate on your net profit about 14.13%. The Social Security portion stops at the wage base — $184,500 for 2026 — while the Medicare portion never stops.

Two things soften it. You deduct half of your self-employment tax above the line, which lowers taxable income. And most self-employed people qualify for the Qualified Business Income deduction of up to 20% of qualified business income, which an employee gets nothing equivalent to.

Withholding is the other half of the problem

A W-2 employee’s tax is taken out of every paycheck and treated as paid evenly across the year. A 1099 contractor receives the gross and is expected to send estimated payments four times a year, on the IRS’s uneven quarters.

This is not a technicality. It is the single most common way a profitable freelance year ends badly: the money arrived, it got spent, and the bill for it came in April. The mechanics — how much to set aside per invoice, the payment dates, and the safe-harbor rule that caps your penalty exposure — are in freelance quarterly taxes: how much to set aside.

What each side can deduct

	W-2 employee	1099 contractor
Payroll tax paid	7.65%	15.3% (on 92.35% of net)
Half of payroll tax deductible	No	Yes
Home office	No	Yes, if exclusive and regular
Mileage and vehicle costs	No	Yes, business miles
Software, tools, equipment	No	Yes
Health insurance premiums	Pre-tax via employer plan	Deductible above the line
Retirement contribution ceiling	401(k) limit	Much higher via SEP or solo 401(k)
Unreimbursed work expenses	Not deductible since 2018	Deductible as business expenses
QBI deduction	No	Usually yes

A worked comparison at $85,000

Two people, same headline number, single filers, nothing unusual.

Alex, W-2, $85,000 salary. Employee FICA at 7.65% is $6,502.50. The employer pays a matching $6,502.50 that Alex never sees. Income tax is withheld from each paycheck. Alex cannot deduct the laptop.

Sam, 1099, $85,000 in invoices with $6,000 of genuine business expenses, so net profit is $79,000.

Step	Amount
Net profit	$79,000
× 92.35%	$72,956.50
× 15.3% self-employment tax	$11,162.35
Less: half deducted above the line	−$5,581.17

Sam pays $4,659.85 more in payroll tax than Alex. The above-the-line deduction of $5,581 returns roughly $1,228 of that at a 22% marginal rate, and the QBI deduction returns more — but the gap does not close, and Sam also funded their own health insurance, equipment and time off out of the same $85,000.

The practical conclusion is the one every contractor eventually reaches: a 1099 number is not comparable to a W-2 number of the same size. As a planning rule of thumb, a contract rate needs to be roughly 25–30% above the equivalent salary before the two are close, and the honest way to work out your own figure is to build it from the bottom up — see how much should I charge as a freelancer.

What does not change

Federal income tax brackets are the same. The standard deduction is the same. State income tax, where it exists, applies to both. Being paid on a 1099 does not put you in a different tax system; it moves who is responsible for the payroll half and when it is due.

Common questions

Is a $100,000 contract better than a $100,000 salary? No. Before benefits are even counted, the extra payroll tax alone is around $7,000 on that profit, and the contract carries no employer health contribution, no retirement match, no paid leave and no unemployment cover.

I have both a W-2 job and 1099 income. What do I do? You can often skip estimated payments entirely by increasing withholding on the W-2 through a new Form W-4. Withholding is treated as paid evenly across the year regardless of when it happened, which is a genuine advantage over estimated payments made late in the year.

Do I need an LLC or an S-corp to fix this? An LLC on its own changes nothing about the tax described here — a single-member LLC is taxed as a sole proprietor by default. An S-corp election changes how self-employment tax applies by splitting pay into salary and distributions, but it adds payroll filings, a reasonable-salary requirement and real annual cost. It becomes worth examining at higher profit levels, with an accountant, not from a table on the internet.
