Retirees often assume one state is much like another for taxes — but Vermont has specific rules that can sharply change the picture. This calculator models how Vermont treats the four most common retirement income streams: Social Security, pensions, IRA/401(k) withdrawals, and military/CSRS pay, applying Vermont’s AGI-based exclusions and its graduated rates.
How it works
Each income type follows its own rule:
- Social Security is fully exempt if federal AGI is at/below $50,000 (single) or $65,000 (married filing jointly). Above that, the exclusion phases out linearly over the next $10,000 of AGI. The calculator computes the excluded fraction and taxes only the remainder.
- Military / CSRS pay gets an exclusion of up to $10,000, subject to the same AGI phase-out.
- Pensions, IRA and 401(k) withdrawals are taxed as ordinary income — no special exclusion.
All taxable retirement income is then stacked through Vermont’s 2025 brackets: 3.35% / 6.60% / 7.60% / 8.75%.
Example and notes
A single retiree with $55,000 AGI receiving $24,000 of Social Security sits inside the phase-out band: with the full-exemption floor at $50,000 and the band ending at $60,000, half the band remains, so 50% of the taxable Social Security is excluded. Pension and 401(k) dollars are taxed in full. The tool shows exactly how much of each stream Vermont reaches.
Because the Social Security exclusion hinges on a hard AGI threshold, even a small change in other income — an extra IRA withdrawal, for instance — can pull more of your benefits into the taxable band. This is a planning estimate; confirm details at tax.vermont.gov before filing.
