How Much Does Vermont Tax on SSDI Benefits?

Vermont is one of a shrinking number of states that still taxes Social Security income — including SSDI (Social Security Disability Insurance) benefits. But the full picture is more nuanced than a simple yes or no. How much Vermont actually taxes your SSDI depends on your total income, your filing status, and whether you qualify for the state's exemption threshold.

Here's what you need to understand about how Vermont's tax treatment of SSDI works.

Vermont Does Tax SSDI — But Not Always

At the federal level, up to 85% of your SSDI benefits may be taxable depending on your combined income (adjusted gross income + nontaxable interest + half of your Social Security benefits). Vermont historically followed that same federal framework, meaning if your benefits were taxable on your federal return, Vermont taxed them too.

However, Vermont has gradually expanded exemptions for lower- and middle-income recipients. As of recent tax years, many SSDI recipients in Vermont owe little or nothing in state tax on their benefits — but that depends heavily on income.

Vermont's Social Security Exemption: The Income Thresholds

Vermont provides a full exemption from state income tax on Social Security benefits — including SSDI — for filers whose adjusted gross income (AGI) falls below a certain threshold. Above that threshold, the exemption phases out.

These figures adjust periodically, but the general structure looks like this:

📋 Important: These thresholds can change with each legislative session. Always verify current figures with the Vermont Department of Taxes or a current-year Vermont tax instruction booklet before filing.

If your AGI is above the upper end of the phase-out range, you lose the exemption entirely and Vermont taxes your SSDI benefits the same way your federal return does — meaning up to 85% of benefits could be included in Vermont taxable income.

What Counts Toward Your Income for This Calculation?

Vermont's exemption is based on your Vermont AGI, which generally mirrors your federal AGI. What matters is your total income picture — not just SSDI.

Factors that can push your income above the exemption threshold include:

• Wages or self-employment income (including during a Trial Work Period)
• Pension or retirement distributions
• Investment income — dividends, capital gains, interest
• Rental income
• Spouse's income if filing jointly
• Other Social Security income, such as retirement or survivor benefits received by a spouse

This is why two SSDI recipients receiving the same monthly benefit can face very different Vermont tax outcomes. One person with no other income may fall fully within the exemption. Another with a working spouse or pension income may find their SSDI fully exposed to Vermont's income tax rate.

Vermont's State Income Tax Rates 💡

Vermont uses a graduated income tax structure. For individual filers, rates generally range from around 3.35% on the low end to 8.75% on the high end, depending on taxable income. The exact bracket thresholds adjust annually.

If you lose the SSDI exemption — partially or fully — whatever portion of your benefits becomes taxable is added to your other Vermont taxable income and taxed at your applicable marginal rate.

For most SSDI recipients whose only or primary income is their monthly benefit, Vermont's average benefit (which fluctuates year to year but typically falls in the $1,200–$1,600/month range nationally) may still place them within the full exemption, depending on other household income.

How Vermont's Tax Treatment Compares to Federal Rules

It helps to understand the two-layer system SSDI recipients face:

Vermont doesn't create a separate formula — it starts with what's already taxable on your federal return and then applies its own exemption on top of that. So if your SSDI isn't federally taxable, it generally won't be Vermont-taxable either.

What Changes Your Tax Picture Year to Year

Several things can shift how Vermont taxes your SSDI from one year to the next:

• Cost-of-Living Adjustments (COLAs): SSA typically issues annual COLAs, which increase your benefit slightly. A meaningful COLA could nudge some filers closer to or past the exemption threshold over time.
• Changes in household income: A spouse returning to work, a new pension payment beginning, or selling an asset can all affect AGI.
• Filing status changes: Divorce, death of a spouse, or remarriage affects which exemption threshold applies to you.
• Legislative changes: Vermont lawmakers have adjusted the exemption thresholds in recent years. What applied last filing season may not be identical to this one.

The Variable Nobody Can Calculate for You

Vermont's rules on taxing SSDI are structured and knowable. The exemption thresholds exist. The phase-out ranges are published. The state's income tax rates follow a defined schedule.

What can't be determined from the outside is where your total income lands relative to those thresholds — and how the combination of your SSDI amount, other household income, filing status, and any deductions places you on that spectrum. Two Vermont residents receiving identical SSDI checks can end up in completely different tax situations. The rules are the same. The inputs are not.
