No Tax on Tips in Montana
↻ Updated 2026 tax yearMontana is one of the states where the federal deduction reaches your state return too. Because Montana starts from federal taxable income and follows the Internal Revenue Code on a rolling basis, Schedule 1-A is already subtracted before Montana applies a graduated schedule from 4.7% to 5.65% — so the same $14,000 saves $1,680 federally and about $658 in Montana tax on top.
Montana starts from federal taxable income and conforms to the Internal Revenue Code on a rolling basis, so the deduction flows through to the Montana return automatically — no state legislation was required.
Montana starts from federal taxable income and conforms to the Internal Revenue Code on a rolling basis, so the deduction flows through to the Montana return automatically — no state legislation was required.
Because Montana conforms, the deduction cuts both bills — but $1,071 of Social Security and Medicare on the same dollars survives either way.
Why the deduction reaches your Montana return
The four OBBBA deductions are below the line: they reduce federal taxable income, and they leave federal adjusted gross income untouched. That is why most states never see them. Montana is an exception because its own calculation begins from federal taxable income rather than from AGI, and because it follows the Internal Revenue Code on a rolling basis rather than freezing to a fixed date.
Those two facts together mean no Montana legislation was needed. The figure Montana starts from already has Schedule 1-A subtracted from it, so the deduction arrived automatically the moment the federal provision took effect.
Montana then applies a graduated schedule from 4.7% to 5.65%. On the $14,000 in the example above, that is worth roughly $658 of state tax — a 4.7% effective rate on that slice of income.
What $14,000 of tips is actually worth in Montana
Take a single filer with $32,000 of other wages and $14,000 of tips — the defaults loaded in the calculator above. Federal taxable income falls by the full $14,000, worth $1,680 at this filer's bracket.
Montana taxable income falls by the same $14,000, worth a further $658. Total saving: $2,338. The $1,071 of Social Security and Medicare on the same dollars is untouched, because these are income tax deductions and payroll tax is a separate system.
Move the sliders to your own numbers and the arithmetic follows. The two things that will not change are Montana's treatment — the deduction flows through and the payroll tax, which applies to the first dollar and the last.
What tips tax relief does not do, in Montana or anywhere
Your tips are still wages. They stay in boxes 1, 3 and 5 of your W-2 — the box 12 code TP is informational — so Social Security and Medicare are computed on exactly the same amount as before, and your employer's withholding does not change because of this deduction.
Only tips in one of the 81 occupations Treasury has published qualify, and only genuinely voluntary tips: an automatic gratuity on a large party is a service charge, which is a wage rather than a tip and is not deductible. The deduction is capped at $25,000 per return and phases out above $150,000 of MAGI ($300,000 filing jointly).
And all four OBBBA deductions expire after tax year 2028. Whatever Montana does between now and then, the federal provision has a fixed end date.
Frequently asked questions
Do I pay Montana state tax on tips?
Yes, but the federal deduction reduces it. Montana starts from federal taxable income with rolling conformity to the Internal Revenue Code, so your Schedule 1-A deduction is already subtracted before Montana applies a graduated schedule from 4.7% to 5.65%.
On the example above, that is worth about $658 of Montana tax on top of the $1,680 federal saving. $1,071 of Social Security and Medicare on the same dollars is unaffected.
How much will the tips deduction save me in Montana?
About $2,338 on the example above: $1,680 federal plus roughly $658 of Montana tax, for a single filer with $32,000 of other wages and $14,000 of tips.
A deduction is worth your marginal rate, not its face value, which is why $14,000 of income produces $1,680 rather than $14,000 of relief. Enter your own figures above for a number specific to you.
Does Montana conform to the federal OBBBA deductions?
Montana starts from federal taxable income and conforms to the Internal Revenue Code on a rolling basis, so the deduction flows through to the Montana return automatically — no state legislation was required.
That determination covers the tips deduction; the senior and car loan interest deductions are tracked separately, though they usually follow the same rule because the mechanism is identical. Our conformity tracker shows all four deductions across all 50 states and DC.
Does the tips deduction reduce my Social Security and Medicare tax in Montana?
No, and not in any state. Qualified tips remain in boxes 3 and 5 of your W-2, so the 6.2% Social Security and 1.45% Medicare are computed on the same wages as before. On the example above that is $1,071 which no OBBBA provision touches.
Combined with Montana's income tax, which the deduction does reduce, that is why the practical relief is smaller than "no tax on tips" implies.
