Louisiana bonus tax calculator
A Louisiana bonus feels heavily taxed, but the missing chunk is withholding, not a bonus tax. Louisiana has no separate bonus rate, so it withholds using the aggregate method (about 3%) on top of the 22% federal prepayment and FICA. Run your numbers to see the "now" withholding next to the "at tax time" total, and how much comes back or is still owed. Everything runs in your browser.
Short version: in Louisiana, a bonus paid on its own is withheld at the flat federal 22%, no separate Louisiana rate — it's withheld as ordinary wages (about 3%), and 7.65% FICA. Treat it as money on account. The real tax is your marginal rate, reconciled on your return; the tool above shows the gap either way.

Louisiana bonus withholding at $5,000, $25,000 and $100,000
Withholding on a $5,000, $25,000, and $100,000 bonus in Louisiana for a single filer earning $70,000:
| Bonus | Federal | Louisiana | FICA | Total | % of bonus |
|---|---|---|---|---|---|
| $5,000 | $1,100 | $150 | $383 | $1,633 | 32.6% |
| $25,000 | $5,500 | $750 | $1,913 | $8,163 | 32.6% |
| $100,000 | $22,000 | $3,000 | $7,650 | $32,650 | 32.6% |
The % shifts as Social Security stops at the wage base; the income-tax portion still trues up when you file.
The three cuts on a Louisiana bonus: federal, state, and FICA
How the federal 22% works. A bonus identified separately from regular wages is withheld at a flat 22% federally (IRS Publication 15). It rises to a mandatory 37% on any bonus dollars past $1,000,000 in a year — the third bracket's rate as a default, not a bonus tax.
Louisiana: no separate bonus rate. With no published supplemental rate, Louisiana withholds a bonus using the aggregate method — combined with your regular pay. Its flat 3% income tax means a separately paid bonus is withheld close to 3%.
Don't expect FICA back. Of the total held back, 7.65% is FICA — Social Security to the wage base, plus Medicare — owed at that rate. That's why the calculator shows the same FICA under "withheld now" and "what it really costs" — there's nothing to refund; only the income-tax portion trues up.

The "Louisiana bonus tax" myth, and what's really withheld
There is no special bonus tax rate. The 22% is a withholding convenience; at filing the bonus is taxed like the rest of your income, at your marginal rate across the brackets. Under 22% (most people) the extra comes back as a refund; over 22% you owe the difference. In this page's $9,000 example, withholding falls about $670 short of the real tax, so you'd owe the rest. Only FICA (7.65%) is a true tax that never returns.
What a $9,000 bonus really costs on a $215,000 Louisiana income
Here's how a $9,000 bonus plays out for a single filer making $215,000 in Louisiana:
- Withheld now: $1,980 federal (22%) + $270 Louisiana + $211 FICA = $2,462 held back, leaving about $6,539 in hand — a 27.4% bite.
- The real bill: at filing the bonus is taxed roughly $2,920 in income tax (federal $2,650 + Louisiana $270), with the identical $211 FICA on top.
- The gap: the 22% withheld falls short of your real rate, leaving about $670 to owe at filing. FICA ($211) stays either way — it's a real tax.

Louisiana and Texas, Mississippi and Arkansas: a bonus-withholding comparison
The same $10,000 bonus and $70,000 salary, in Louisiana and its neighbors Texas, Mississippi and Arkansas:

| Texas | no state income tax | $0 | $2,965 |
| Mississippi | aggregate method | $400 | $3,365 |
| Arkansas | flat 3.7% | $370 | $3,335 |
Figures are the 22% federal plus state plus FICA for a single filer; the income tax you owe reconciles on your return.
Louisiana bonus tax FAQ
Does Louisiana have a separate bonus withholding rate?
No. Louisiana has no separate supplemental rate, so a bonus is withheld with the aggregate method — as if it were part of your regular wages, effectively near 3%.
Is there a special bonus tax rate in Louisiana?
No. The 22% federal and the state supplemental rate are withholding defaults, not rates that apply only to bonuses. Your real tax is your ordinary marginal rate.
What rate does Louisiana withhold on a bonus in 2026?
Louisiana's supplemental withholding is about 3% (aggregate method), added to the flat 22% federal prepayment (37% on bonus pay over $1,000,000/yr) and 7.65% FICA. Only the income-tax portion is a prepayment; it trues up at your real rate.
Does my Louisiana bonus ever come back at tax time?
The income-tax part can. If the flat 22% over-withheld relative to your real marginal rate, the excess is refunded; if you're a high earner above 22%, you pay more. FICA is never refunded.
