Vermont Income Tax Withholding for Employers: W-4VT, WHT-436 Quarterly, the January 31 Annual Reconciliation and the 30-Day Rule
Vermont Income Tax Withholding for Employers: W-4VT, WHT-436 Quarterly, the January 31 Annual Reconciliation and the 30-Day Rule
If you have employees working in Vermont, you are responsible for Vermont withholding tax. You take state income tax out of each paycheck, deposit it on a set schedule, report it every quarter and reconcile the full year in January. The steps are not complicated, but they have to run in the right order, and the deadlines are strict. Here is the sequence, with the forms and dates you need.
This guide is informational content, not legal or tax advice. Withholding rules, rates and forms change, and the Vermont Department of Taxes is the final authority. If your payroll involves employees in several states, remote staff or an unusual pay arrangement, talk with a qualified CPA or attorney before you file.
Step 1: Register a withholding account on myVTax
Start with the account. Vermont withholding is administered by the Vermont Department of Taxes, and you register on myVTax before you run your first payroll. The withholding account is separate from your sales and use tax account, so a registration for one does not cover the other. Vermont has no general statewide business license, so this tax account is the state registration most employers need, alongside the Secretary of State filing that formed your entity, if you formed one. Keep the account number and login with your payroll records from day one.
Step 2: Collect W-4VT with every federal W-4
Each employee completes Form W-4VT, Vermont's withholding certificate, alongside the federal Form W-4. Collect both on the first day, file them in the employee record and use the W-4VT to set the Vermont amount withheld. The federal W-4 does not substitute for the W-4VT, so a missing Vermont form is a gap you will have to close later, and it is far easier to collect it at hire.
Vermont personal income tax rates
Vermont's personal income tax has four brackets. For tax year 2025 the rates are 3.35%, 6.6%, 7.6% and 8.75%. The tax year 2026 schedule was not yet published as of October 28, 2026, so check tax.vermont.gov for the current brackets before you set 2026 withholding. Do not carry 2025 figures forward into 2026 payroll.
Step 3: Choose the right deposit schedule
Vermont's payment frequency mirrors the federal schedule, so you will see the same three patterns: semiweekly, monthly, or quarterly with the WHT-436. Confirm which one applies to your business with the Department of Taxes rather than guessing. A wrong schedule means late deposits, and late deposits carry penalties and interest. The table below shows the due dates for each schedule.
| Schedule | Payday or trigger | Deposit or report due |
|---|---|---|
| Semiweekly | Paydays on Wednesday, Thursday or Friday | The following Wednesday |
| Semiweekly | Paydays on Saturday, Sunday, Monday or Tuesday | The following Friday |
| Monthly | Withholding deposited monthly | The 25th of the following month (January's is due February 23) |
| Quarterly | Reported on the WHT-436 | Each quarter; confirm the exact date on tax.vermont.gov |
Late deposits and reports can bring penalties and interest, and the Department sets those amounts, so confirm current rates on its website before you assume any figure.
File the WHT-436 quarterly reconciliation
The WHT-436 is your quarterly reconciliation, and it is due each quarter. It reports the withholding you took from wages, so reconcile the quarter's deposits against your payroll register before you file. Confirm each quarterly due date on tax.vermont.gov before you add it to your calendar.
The same WHT-436 also carries the Child Care Contribution. That contribution is separate from income tax withholding, but it is reported on the same form, so make sure it is reported correctly even though it is a different tax. Unemployment insurance is also a separate obligation, and your Vermont withholding deposits do not satisfy it.
The January 31 WHT-434 annual reconciliation
The WHT-434 is your annual reconciliation, and it is due the last day of January. If that day falls on a weekend, the deadline moves to the next business day. For the 2026 year, January 31, 2027 is a Sunday, so the WHT-434 is due Monday, February 1, 2027. Confirm the filing date with the Department before you rely on it.
Plan the year-end close before the holidays. Reconcile your four quarters of WHT-436 totals against the payroll register, then prepare the W-2 and 1099 forms that go with the WHT-434 so the annual totals match.
E-filing is mandatory if any of these apply
- You file 10 or more W-2 or 1099 forms with the WHT-434.
- You pay withholding on the semiweekly schedule.
- You use a payroll service.
- You remitted more than $100,000 of withholding in the prior calendar year.
If none of these applies to you, e-filing is not mandatory, but check the filing options on tax.vermont.gov before you choose a method.
Report new hires within 10 days
New hire reporting is a separate filing with the Vermont Department of Labor, made through its e-Services system within 10 days of the employee's first day of work. You will need the employer name, address and FEIN, plus the employee's name, address, Social Security number and hire date. Build this into onboarding rather than the month-end close, because the 10 days start on the first day of work, not on the first payday.
The 30-day rule for out-of-state employers
If your business is based outside Vermont, you do not start Vermont withholding on an employee's first day in the state. You must begin withholding once that employee has worked from a Vermont location for 30 days. Keep a running count of Vermont workdays for each out-of-state employee so you know when the 30th day arrives and can start withholding on time.
Remote workers who live in Vermont are the exception to watch. An employee who lives in Vermont and works remotely is taxed from day one, even if that employee claims another state as domicile. A company based in New Hampshire that hires a Burlington resident to work from a home office starts Vermont withholding from that employee's first day. Check the residency of every remote worker at hire, not after the first quarter closes.
Owner estimates and the $250 entity tax
Owner estimates are separate from employee withholding. If you are self-employed, you pay Vermont estimated income tax on April 15, June 15, September 15 and January 15. You are protected if your payments total 90% of this year's tax or 100% of last year's tax. These estimates do not replace withholding for your employees, and they do not go into your withholding account.
Pass-through entities also owe a minimum annual entity tax of $250, paid with the business income tax return on Form BI-471 or BI-476. The tax covers S corporations, partnerships and LLCs taxed as partnerships. It does not apply to a disregarded single-member LLC. Do not confuse it with withholding, and do not send it to the withholding account.

| WHT-434 annual reconciliation | Last day of January, moving to the next business day if it falls on a weekend |

Common mistakes to avoid
- Using the sales tax account for withholding. Register the withholding account separately on myVTax.
- Collecting the federal W-4 but not the W-4VT.
- Treating a Vermont resident who works remotely as untaxed until a later date. That employee is taxed from day one.
- Forgetting the Child Care Contribution on the WHT-436.
- Leaving the WHT-434 until February. The due date is the last day of January, moved only for a weekend.
- Assuming e-filing is optional for you. Semiweekly depositors and payroll service users must e-file.
Where to confirm the details
The Vermont Department of Taxes is the authority on withholding forms, due dates, rates and the 2026 bracket schedule once it is published. Start at tax.vermont.gov and confirm any figure in this guide before it affects a live payroll run.
A payroll service can handle deposits, forms and mandatory e-filing for you, but it charges a fee, so compare that cost with the hours you would spend on the schedules above. If you have multistate staff or a growing team, have a qualified CPA review the setup before your first payroll runs.
