For many retirees, Social Security represents a core source of income. What often comes as a surprise is that these benefits may not be entirely tax-free. Depending on your overall income, up to 85% of your Social Security benefits could be subject to federal taxes, reducing the amount you actually keep.
Understanding how Social Security is taxed and how it fits into your broader retirement income plan is essential for making informed financial decisions. The rules are based on something the IRS calls “combined income” (also known as “provisional income”), which factors in not only your benefits but also other sources like pensions, wages, dividends, and withdrawals from retirement accounts.
Understanding How Social Security Is Taxed
The taxation of Social Security benefits is determined by the IRS combined income formula. Combined income includes your adjusted gross income, any tax-exempt interest, and half of your Social Security benefits. This figure is then compared against specific thresholds to determine how much of your benefits may be subject to federal tax.
For single filers (in 2025)
- Up to $25,000 in combined income: no tax on Social Security benefits.
- Between $25,000 and $34,000: up to 50% of benefits may be taxable.
- Over $34,000: up to 85% of benefits may be taxable.
For married couples filing jointly:
-
For married couples filing jointly (in 2025):
- Up to $32,000 in combined income: no tax on Social Security benefits.
- Between $32,000 and $44,000: up to 50% of benefits may be taxable.
- Over $44,000: up to 85% of benefits may be taxable.
To illustrate, consider a married couple receiving $30,000 in Social Security benefits and another $25,000 in other income. Half of their Social Security ($15,000) plus the $25,000 equals $40,000 in combined income. This places them in the range where up to 50% of their benefits are taxable.
The rules mean that while Social Security was designed as a cornerstone of retirement income, its tax treatment depends heavily on your overall financial picture. Understanding how the formula works is the first step toward planning withdrawals and coordinating income in a way that helps preserve benefits.

Recent Legislative Updates
At the federal level, Social Security benefits may be taxed based on combined income, with higher earners potentially owing tax on up to 85% of their benefits. State rules, however, vary significantly. While a handful of states impose their own tax on Social Security, the majority, including Massachusetts, do not. This means that retirees in Massachusetts do not pay state income tax on their Social Security benefits.
Still, federal taxation and other sources of income, such as IRA withdrawals, pensions, or investment gains, remain important factors in determining the net amount retirees keep. For many households, the real challenge is not state-level taxation but how federal rules interact with broader retirement income streams.
This is where retirement planning strategies become essential. Coordinating the timing of Social Security benefits with withdrawals from taxable, tax-deferred, and Roth accounts can help retirees reduce exposure to federal taxes, while ensuring a reliable income stream. In Massachusetts, where state taxes are not a concern for Social Security, the focus can shift toward optimizing federal outcomes and protecting other parts of the financial plan, such as investment accounts and estate planning.
By integrating both federal and state considerations into a cohesive strategy, retirees can avoid unnecessary tax burdens and preserve more of their wealth to support long-term goals.

Planning Strategies to Reduce Social Security Taxation
Even with recent tax law changes, higher-income retirees may still see a portion of their Social Security benefits taxed. The good news is that thoughtful planning can help reduce the impact. The goal is not only to minimize taxes in a single year but to manage income in a way that reduces exposure over the course of retirement.
Manage Withdrawals Across Accounts
Coordinating withdrawals from taxable, tax-deferred, and Roth accounts is one of the most effective tools for controlling combined income. Strategic withdrawal strategies can help smooth income levels across years, preventing spikes that push benefits into taxable territory. This approach also supports diversification, allowing portfolios to balance growth and protection.
Consider Roth Conversions
Roth conversions can be valuable when income is temporarily lower, such as in early retirement before required minimum distributions begin. Converting assets today reduces future tax liabilities and creates tax-free income later, which can limit the percentage of Social Security subject to tax. These decisions should always be evaluated in the context of broader tax strategy planning, since short-term costs need to be weighed against long-term benefits.
Coordinate Claiming Age With Other Income
The age at which you claim Social Security has implications beyond the benefit amount. Delaying benefits allows for higher monthly payments and may provide room to draw from other accounts first. This can help manage combined income levels and reduce taxation of benefits over time. Our earlier blog on creating a tax-efficient retirement income strategy explores how timing and coordination across income sources can preserve more wealth.
Leverage Charitable Giving
For retirees with philanthropic goals, qualified charitable distributions (QCDs) allow IRA withdrawals to be directed to charity. These distributions satisfy required minimum distributions without increasing taxable income, helping to limit the portion of Social Security subject to tax.
Keep Plans Flexible
Because tax laws and personal circumstances evolve, strategies must be revisited regularly. Annual reviews can ensure your retirement income plan remains aligned with current rules and long-term goals.
By combining these strategies, retirees can manage the complex interaction of income sources, taxes, and benefits to build a more sustainable retirement plan..
When Professional Guidance Can Help
For many retirees, the rules around Social Security taxation can feel complex. Coordinating withdrawals, evaluating Roth conversions, and managing required minimum distributions all require careful timing. Small missteps, such as taking income in the wrong order or missing an opportunity to reduce taxable benefits, can have lasting effects on retirement income.
Working with a fiduciary financial advisor provides clarity and confidence. Fiduciaries are required to put their clients’ interests first, which means strategies are designed to maximize long-term outcomes rather than short-term gains. At Greenway, our team brings experience in retirement planning, investment management, and tax strategy, helping clients align Social Security decisions with the rest of their financial lives.
Choosing a fiduciary financial advisor also removes conflicts of interest. As a fee-only firm, Greenway is compensated directly by clients, not by commissions or product sales. This structure reinforces transparency and trust—qualities that are especially important when managing the income you’ll rely on for decades.
For retirees approaching these decisions, professional guidance can transform uncertainty into a clear plan. With thoughtful strategies in place, Social Security can serve as a stable cornerstone of retirement income rather than a source of tax surprises.
Social Security is designed to provide a foundation of income in retirement, but how it interacts with your broader financial picture determines how much of those benefits you ultimately keep. Understanding the combined income formula, staying informed about legislative changes, and coordinating benefits with investment withdrawals are all essential steps in protecting retirement income from unnecessary taxation.
The right strategy balances flexibility with discipline. Markets evolve, tax laws shift, and personal goals change over time. A plan that integrates Social Security with investment management, tax planning, and estate considerations can help ensure your income remains reliable. That’s why many households find value in a partner who brings both technical expertise and a fiduciary commitment to their best interests.
