W-2 and 1099 in the same year?
Here’s what you actually owe.

You worked six shows on payroll and invoiced four more yourself. Now you’re trying to figure out what to set aside, and every calculator you find asks for one number.

That’s the whole problem. What your 1099 work costs you in tax depends entirely on what your W-2 work already did to your return. Feed a flat-rate calculator only the freelance figure and it hands you an answer that’s usually too high, sometimes too low, and never the one you needed.

Below is what’s actually moving, in roughly the order it hits your return.

The “set aside 30%” rule breaks when you have both

The number you need is a difference between two numbers. Work out what you’d owe on everything combined, then work out what you’d owe on the W-2 income alone. The gap is what your freelance work costs you.

Run that on two people who both invoiced $30,000 and you get two different answers, because one of them also had $40,000 on payroll and the other had $160,000.

So when someone in a Facebook group tells you 30%, they’re describing their own return. It might be close to yours. There’s no way for either of you to know.

Social Security has a ceiling. Medicare doesn’t.

This is the part that trips up nearly everyone, and it’s usually the biggest single swing in the answer.

Self-employment tax is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare.[1] The Social Security half stops once your earnings for the year hit the wage base. For 2026 that’s $184,500.[2]

Here’s what matters for mixed income: your W-2 wages fill that bucket first. Payroll already took Social Security out of them, so they count toward the cap before your freelance profit gets anywhere near it.

That one interaction can be worth several thousand dollars, and a calculator that never asked about your W-2 income can’t possibly find it.

Medicare works differently. There’s no ceiling on the 2.9%, and above $200,000 (single) or $250,000 (married filing jointly) there’s an extra 0.9% Additional Medicare Tax on top.[1] Your W-2 wages eat into that threshold first as well, which is why a good payroll year can push your freelance income into the surtax even when the freelance number by itself looks small.

Three people, the same $30,000 of freelance work

Same invoices, same $3,000 of expenses, same filing status. Only the payroll income changes.

Two things worth staring at.

The same freelance work costs one person $4,534 and another $7,463. Any single percentage you’ve been given is right for exactly one of these rows.

And look at the Social Security column on the bottom row. It drops by $1,294 even though that person earned the most, because $170,000 of payroll wages had already filled most of the wage base. Their income tax went up, their Social Security tax went down.

Single filer, standard deduction, no state income tax, 2026 figures, before any overtime deduction. Your numbers will differ. That’s the point.

You only pay SE tax on 92.35% of your profit, and half of it comes back

Two adjustments that people forget, both in your favor.

Self-employment tax applies to 92.35% of your net profit, not all of it. That’s line 4a on Schedule SE, and it exists because an employer would have deducted its half of payroll tax as a business expense.

Then half of the self-employment tax you do owe comes off your income as a deduction.[1] You take it whether or not you itemize.

So the 15.3% headline is misleading in both directions. It’s charged on less than your full profit, and part of it reduces your income tax bill. Neither adjustment touches the Additional Medicare surtax.

The overtime deduction probably covers less of your overtime than you think

New for 2025 and 2026, and relevant to anyone working broadcast, live events or film, because those W-2s carry a lot of overtime.

You can deduct up to $12,500 of qualified overtime ($25,000 filing jointly), and it phases out above $150,000 of modified AGI ($300,000 jointly). You need a valid SSN and you can claim it without itemizing.[6]

Three catches, and they’re big ones.

Only the premium half counts. If you’re paid time and a half, the deductible piece is the extra 0.5x, not the whole 1.5x payment. On $6,000 of time-and-a-half pay, roughly $2,000 is “qualified overtime.”

It has to be FLSA overtime. The IRS is explicit that overtime owed to you under a collective bargaining agreement, but not required by section 7 of the Fair Labor Standards Act, doesn’t qualify.[7] Plenty of crew overtime is contract overtime. Golden time, turnaround penalties, sixth and seventh day bumps, meal penalties. Much of that sits outside FLSA, and outside the deduction.

It’s income tax only. Your Social Security and Medicare withholding doesn’t change.

For 2025, employers weren’t required to break qualified overtime out separately on your W-2, so you may have to work the figure out yourself from pay stubs using the Schedule 1-A instructions. Check your 2026 W-2 for a separate line before you assume it isn’t there.

That 1099 number is gross, and the mileage rate moved mid-year

Every dollar on a 1099-NEC is revenue. Your tax comes off profit. Kit rental, expendables, a hard drive for a shoot, your own airfare when the production didn’t cover it, gear insurance, union dues. All of it comes off before tax is calculated.

Mileage is the one crew consistently under-claim, partly because the pattern is unusual. Three locations in a day, no fixed office, a truck stop and a return at 2am. Log it.

What a per diem does to you depends on who paid it

Worth separating, because crew get both kinds in the same year.

On a W-2 show, a per diem paid under an accountable plan at or under the federal rate stays off your W-2 entirely. It isn’t wages, and you don’t deduct the meals it covered. Nothing to do.

On a 1099 gig, the per diem usually lands inside the number on the form. It’s income. You then deduct what you spent, and you can use the federal standard meal allowance instead of keeping every receipt. Meals are limited to 50% either way, and there’s no per diem shortcut for lodging: that one’s actual cost only.[12]

So a $70 travel day on a payroll show and a $70 travel day on an invoice do not land the same way, and the invoice version needs a record.

Retirement and health premiums cut one tax, not the other

Money into a SEP-IRA or solo 401(k) reduces your income tax. It does nothing to your self-employment tax.

Self-employed health insurance premiums work the same way. Deductible against income, invisible to SE tax.

This matters when you’re deciding what to do with a good year. A $10,000 SEP contribution doesn’t save you 15.3% plus your bracket. It saves you your bracket. Still worth doing, just not worth as much as the arithmetic you did in your head.

The 20% deduction you probably already qualify for

Section 199A lets most self-employed people deduct up to 20% of qualified business income, and you get it whether you itemize or take the standard deduction.[13]

Your freelance profit, after the self-employment tax deduction, generally counts. Your W-2 wages never do. The deduction is also capped at 20% of your taxable income before it, which is why a big payroll year and a small freelance year can quietly limit it.

It reduces income tax only. Self-employment tax is calculated before any of this. The calculator applies it automatically; above roughly $200,000 of taxable income the real rules get complicated enough that you want a CPA rather than a calculator.

Safe harbor, and the withholding move most crew never hear about

The penalty for underpaying turns on whether you paid enough as the year went along, quarter by quarter. What you finally owe in April is a separate question.

You’re clear of it if your withholding and estimated payments add up to the smaller of:

• 90% of this year’s total tax, or
• 100% of last year’s total tax (110% if last year’s AGI was over $150,000, or $75,000 married filing separately)

The penalty only applies at all if you’ll owe $1,000 or more after withholding.[3]

The prior-year option is the useful one. If last year was quiet and this year is enormous, you can clear the penalty on last year’s much smaller number and settle the rest in April.

Now the part that’s specific to having a W-2. Withholding counts as if it were paid evenly across the year, no matter when it actually came out of your check. The Form 2210 instructions treat one fourth of your annual withholding as paid on each due date by default.[4]

So if you blew through Q1 and Q2 without paying anything, and you’ve got a staff gig in the fall, filing a new W-4 to withhold extra from those checks can retroactively patch the earlier quarters. A late estimated payment can’t do that. It arrives when it arrives.

It’s the single most useful thing about having both income types, and no generic 1099 calculator will ever tell you, because it doesn’t know you have a W-2.

If your year is back-loaded, don’t pay in four equal pieces

Football and basketball seasons don’t spread revenue evenly, and neither does a fall festival run.

The default assumption is that you earned your income in even quarters. Earn most of it between September and December and you’ll look underpaid in Q1 and Q2 even though you had nothing coming in.

The fix is the annualized income installment method, Schedule AI on Form 2210. It recalculates each required payment based on what you’d actually earned by that point in the year. It’s more paperwork, and for a seasonal year it can wipe out the penalty entirely.

One rule: if you use it for one due date, you have to use it for all of them.[4]

The calculator has a quarter-by-quarter mode for exactly this. Put your real income where it landed and the picture changes.

Fewer 1099s in 2026 doesn’t mean less income to report

Two reporting thresholds moved, and both create the same trap.

The 1099-NEC threshold went from $600 to $2,000 for tax years beginning after 2025.[8] It’s indexed for inflation from 2027 onward. Separately, the 1099-K threshold reverted to $20,000 and 200 transactions.[9]

So if you did four $900 days for four different producers, you may get no forms at all this year where you’d have gotten four last year.

You still owe tax on every dollar. The threshold only changed what gets reported to the IRS. The practical risk is that your own records are now the only record, and a shoebox of Venmo notifications isn’t one.

Some states set their own thresholds below the federal one, so you may still get a form from a state where the payer files.

Working in four states

If you shot in Georgia, Texas, Ohio and Tennessee, you may owe nonresident returns in some of them. Texas and Tennessee have no state income tax on wages. Georgia and Ohio do.

Your home state generally taxes all of your income and then gives you a credit for tax paid to other states, so you’re not usually taxed twice. You are usually filing more returns than you expected.

The calculator uses a simplified single-state rate, which is enough for a set-aside figure. It won’t do your multi-state return.
