State Social Security Tax Rules for Retirees

Many retirees focus on federal taxes when planning their budget, but it is equally important to understand how local jurisdiction affects your net income. While the federal government may claim a portion of retirement, survivor, and disability payments if your combined income exceeds federal thresholds, specific state laws add another layer of complexity.

Currently, nine states impose some form of tax on Social Security income. However, the rules are far from uniform; liability typically hinges on total household income and the taxpayer's age.

State-Specific Guidelines for Social Security Taxation

Although it is always advisable to consult with a local tax professional regarding your specific situation, the following is a breakdown of how various states handle these benefits:

Colorado: Age is a primary factor here. Residents aged 65 and older are permitted to subtract the entirety of their Social Security benefits from their taxable income. For those between the ages of 55 and 64, full deduction is allowed if adjusted gross income (AGI) does not exceed $75,000 for single filers or $95,000 for couples. Above these caps, the deduction is limited to $20,000.
Connecticut: This state offers a full deduction for individual filers with an AGI of $75,000 or less, and joint filers earning $100,000 or less. If income surpasses these levels, the state caps the tax so that no more than 25% of benefits are subject to taxation.
Minnesota: Taxation here is tiered. Benefits are fully tax-exempt for joint filers earning up to $108,320, single/head of household filers up to $84,490, and married separate filers up to $54,160. A partial tax applies to income falling within the next bracket (up to $144,320 for couples and $120,490 for singles). Earnings beyond these upper limits result in state taxation mirroring federal taxable levels.
Montana: Full deductions on retirement income are available for individuals with an AGI under $25,000 and couples under $32,000. Those exceeding these thresholds will see a portion of their Social Security income taxed.
New Mexico: The state provides exemptions for single filers earning under $100,000 and married couples filing jointly who earn less than $150,000. Married couples filing separately are exempt if they earn below $75,000.
Rhode Island: Benefits are completely exempt for joint filers with income of $130,250 or less. For single filers and heads of households, the exemption threshold is $104,200.
Vermont: Full exemptions apply to joint filers earning $65,000 or less; for other filing statuses, the cap is $50,000. A partial phase-out occurs for joint filers earning between $65,000 and $75,000, and other filers earning between $50,000 and $60,000. No exemption is available for those earning above these ranges.
West Virginia: Current laws may tax benefits if income hits $50,000 for singles or $100,000 for couples. However, legislative changes are in motion. For the 2025 tax year, filers above these thresholds can deduct 65% of their benefits, and the state plans to eliminate the tax on Social Security entirely by the following year.

How States Determine Tax Liability

State governments generally utilize one of two methods—or a combination thereof—to determine if you owe taxes on your benefits:

Age-Based Criteria: Some jurisdictions offer preferential treatment to older retirees. Colorado, for instance, generally exempts residents over the age of 65 from these taxes, whereas younger beneficiaries may still be liable.

Income-Based Thresholds: States like New Mexico utilize an income cliff or phase-out system. In these scenarios, Social Security is only included in taxable income once total earnings surpass a specific dollar amount.

Many states facilitate this through a specific "subtraction" or deduction line item on their state tax return forms.

Strategies to Limit Tax Exposure

Reducing taxable income is the most effective method for preserving the full value of Social Security benefits. Financial planning tools can be utilized to keep adjusted gross income below the thresholds mentioned above.

Roth IRA Distributions: Because contributions to a Roth IRA are taxed upfront, qualified withdrawals in retirement are tax-free. These distributions do not count toward the income calculations that trigger taxes on Social Security.
Health Savings Accounts (HSAs): Funds withdrawn from an HSA for qualified medical expenses are tax-free. If a retiree utilized a high-deductible health plan during their working years and saved receipts, they can reimburse themselves in retirement without increasing their taxable income.

Beyond personal finance adjustments, there is also a legislative route. There is a growing national trend toward repealing these taxes, and advocacy at the state level continues to push legislatures to remove Social Security from the tax rolls completely.
