How a Vermont paycheck works
Vermont's withholding is the plain version of a graduated state income tax. Your employer annualises your pay, subtracts a fixed amount for each allowance you claimed on Form W-4VT, and runs what is left through a rate table. There are two tables: one for married employees, one for everybody else. Then it divides back down to your pay period.
There is no state standard deduction inside the withholding calculation, no credit subtracted at the end, and no local income tax anywhere in Vermont. The allowance is the only thing that comes off, which makes it the single lever you have over what is withheld.
Federal income tax withholding
Federal withholding annualises the wage, subtracts the standard deduction that matches the filing status on Form W-4 Step 1, applies the graduated schedule for that status, and deducts the dependent credit from Step 3. This page models a W-4 with Steps 2 and 4 left blank: one job, no spouse income, no other income, no extra withholding. Above the income limit for the status, the dependent credit tapers by a set amount for every thousand dollars of excess rather than disappearing at a cliff.
Social Security and Medicare
Social Security applies a flat rate to wages up to an annual ceiling that is re-indexed each year, so it stops partway through the year for a high earner. Medicare applies to every dollar, and above a fixed wage threshold the employer withholds the Additional Medicare tax on the excess, with no employer match and no regard for filing status.
Head of household is withheld as single
Vermont publishes two withholding tables, not three. Married goes on the married table; single and head of household share the other one. So selecting head of household lowers your federal withholding, because the federal system does have a third schedule, but it leaves the Vermont line exactly where single leaves it.
The married table is not simply the single one doubled. Its lowest band starts higher and its upper boundaries sit at different places, so a married couple and two single filers on the same combined income are not withheld the same.
Form W-4VT and the allowances
Vermont has its own withholding certificate rather than relying on the federal W-4, and the value of one allowance is set for the year and indexed. Each allowance you claim comes straight off your annualised wage before the table, so its worth to you depends on which band you are in: the same allowance saves more at the top rate than at the bottom.
If you have never filed a W-4VT, your employer falls back to treating you as single with no allowances, which withholds the most. That is the safe default from the state's point of view and usually the wrong one for yours, so it is worth checking whether a W-4VT is on file.
The first band is zero
The bottom of each Vermont table charges nothing at all. Below that point nothing is withheld for the state, and above it the tax starts from zero and climbs, rather than jumping. That means a low-paid employee, or anyone with enough allowances to bring their annualised wage under the line, sees no Vermont line on a payslip even though Vermont has an income tax.
Where these figures come from
Vermont publishes its withholding tables in an annual booklet from the Department of Taxes. That booklet could not be retrieved for this page, so the tables here come from the United States Department of Agriculture's National Finance Center, the federal payroll provider that has to implement each state's published method for the federal employees it pays. It publishes its Vermont tables as a dated, numbered bulletin.
That is a second-hand source, and this page says so rather than hiding it. The figures are internally consistent to the cent, which is what you would expect from a faithful transcription rather than a reconstruction, but they have not been checked against a worked example from Vermont itself. If your payslip disagrees with this page, trust your payslip.
What Vermont does not charge
There is no county or city income tax in Vermont, so where you live inside the state does not change this figure. There is no employee-side state levy modelled here either: no disability insurance premium, no paid family leave deduction.
What the employer pays on top
The employer matches Social Security and Medicare and pays federal unemployment tax at its net rate. Vermont unemployment insurance is charged to the employer at a rate set from its own claims record on a state wage base, so it is left out.
What this calculator assumes
The figure models a salaried employee paid evenly across the year with a standard Form W-4 and Form W-4VT, and no pre-tax deductions. It leaves out:
- Pre-tax contributions such as a 401(k), health premiums, HSA or flexible spending accounts, which reduce the wages subject to income tax and often to FICA.
- Extra withholding requested on the federal or state certificate, and the W-4 Step 2 and Step 4 adjustments.
- Bonuses, lump sums and other supplemental wages, which the state booklet covers separately.
- Vermont credits and adjustments claimed on the annual return.
- Employer-side state unemployment insurance, which is priced per employer, and any federal unemployment credit reduction.
- Employees outside the normal Social Security system, such as some public-sector staff and certain visa holders.
Withholding versus your final tax bill
Withholding is a prepayment. The annual returns, federal and state, replace these standard assumptions with your real situation: deductions, other income, and credits payroll knows nothing about. One job usually produces a refund; two jobs, a working spouse or investment income often produce a balance due.
