If you’re approaching retirement, you may have heard discussions about changes tied to the “OBBBA” (often referred to as the “Big Beautiful Bill Act”) and how it might affect retirement income. One of the most frequent questions people ask our team at 1st Choice Financial Services, Inc., your local Central PA financial planners, when focusing on retirement planning, is pretty basic:

“Will my Social Security still be taxed under the new OBBA rules?”

The answer depends on several factors, especially your total retirement income and the structure of your withdrawal strategy. Changes to tax laws can also influence how benefits are treated over time, which we’ll also explore in this article.

For residents in communities like Camp Hill, Harrisburg, and Hershey, 1st Choice Financial Services, Inc. provides the local expertise needed to navigate Social Security taxation under these new rules, helping you make more informed decisions for your future income planning.

What Is the OBBBA and Why Does It Affect Social Security Taxes?

The One Big Beautiful Bill Act (OBBBA) is a federal tax reform law that updates several provisions affecting retirement income. While Social Security benefits may still be taxable, the legislation introduces a new tax deduction for certain older taxpayers that could reduce overall taxable income and, in some cases, lower the portion of benefits included in taxable income for some retirees.

The OBBBA is part of a broader effort to adjust federal tax rules that affect individuals and families, including retirees. While it does not directly remove Social Security taxation or change the existing taxation formula, it introduces provisions that may influence how retirement income is treated under the tax code.

Because Social Security taxation depends heavily on overall income, adjustments to deductions and other tax provisions can influence how much of your benefits are taxable. 

Understanding how these changes interact with Social Security income can provide helpful context when you’re evaluating long-term retirement income strategies.

How Were Social Security Benefits Taxed Before OBBBA?

Before the One Big Beautiful Bill Act (OBBBA), Social Security benefits were taxed based on a formula known as “combined income”. Depending on total income, up to 50% or 85% of benefits could be included in your gross taxable income. The income thresholds used in this calculation were established in legislation passed in 1983 and 1993 and were never adjusted for inflation.

Combined income was calculated by adding:

• Adjusted Gross Income (AGI)
• Non-taxable interest (such as certain municipal bond income)
• 50% of Social Security benefits

This total determined how much of a retiree’s benefits could be included in taxable income.

For single filers:

• Below $25,000: benefits are generally not taxable
• $25,000–$34,000: up to 50% of benefits potentially taxable
• Above $34,000: up to 85% of benefits potentially taxable

For married couples filing jointly:

• Below $32,000: benefits are typically not taxable
• $32,000–$44,000: up to 50% of benefits potentially taxable
• Above $44,000: up to 85% of benefits potentially taxable

Importantly, this did not mean benefits were taxed at 50% or 85%. Instead, it meant that up to that portion of benefits could be included in taxable income, where it would then be taxed at the retiree’s ordinary income tax rate.

Because these thresholds were never indexed for inflation, more retirees gradually crossed them over time. Cost-of-living adjustments, retirement account withdrawals, pensions, and investment income increasingly pushed retirees into ranges where part of their Social Security benefits became taxable.

For many households, this meant that Social Security taxation was closely tied to other retirement-income decisions. Withdrawals from IRAs or 401(k)s, Required Minimum Distributions (RMDs), and investment income could all increase combined income and affect how much of a benefit was taxed. As a result, retirement planning should focus on coordinating income sources to manage overall taxable income.

While these 1983/1993 thresholds created “tax creep” for decades, the OBBBA introduces a new senior tax deduction that may help reduce overall taxable income for some retirees.

How Does OBBBA Change the Taxation of Social Security Benefits?

The One Big Beautiful Bill Act (OBBBA) introduced changes that may reduce overall federal tax liability for many retirees. While the legislation does not change the existing Social Security taxation formula or income thresholds, it introduces provisions that may lower taxable income for certain individuals. Because Social Security taxation depends on total income, reductions in taxable income may reduce the portion of benefits included in taxable income for some retirees.

Why Was Social Security Taxation Revisited?

As discussed earlier, the previous system relied on combined income thresholds that had not been updated for inflation since the 1980s and 1990s. Over time, this led many policymakers to refer to it as a “tax creep”. As retirement income gradually increased due to cost-of-living adjustments, pension payments, or retirement account withdrawals, more retirees crossed the income thresholds that triggered Social Security taxation.

As a result:

• Millions of retirees saw up to 50% or 85% of their benefits included in taxable income.
• Even moderate retirement income levels may be subject to taxation.
• Required Minimum Distributions (RMDs) often pushed retirees into higher tax brackets.

The OBBBA legislation was introduced in part to provide broader tax relief for certain taxpayers, including older individuals.

What Changes Did OBBBA Introduce?

Under the OBBBA framework, federal tax treatment of retirement income includes new provisions that may provide relief for many retirees. While the law does not directly change how Social Security benefits are taxed, it introduces deductions and tax adjustments that may reduce overall taxable income for some individuals.

Key elements of the new approach include:

• Senior Deduction Relief: Introduces a tax deduction for certain taxpayers age 65 and older that may reduce overall taxable income. Lower taxable income may reduce the amount of Social Security benefits subject to federal taxation for some retirees.
• Indirect Tax Relief: Because Social Security taxation is based on total income, reductions in taxable income may reduce the portion of benefits included in taxable income for some households.
• Direct Income Interaction: For many individuals with moderate retirement income, these changes may reduce overall tax exposure depending on how different income sources interact.
• Coordinated Strategy: Maintains interaction with other income sources, such as IRA withdrawals, pensions, and investment income, helping to ensure total income remains the primary driver of taxability.

How May OBBBA Impact Social Security Taxes?

The impact of the One Big Beautiful Bill Act (OBBBA) often depends on the broader structure of your retirement income. While the new legislation may provide relief for many, your Social Security benefits may still be included in your taxable income, depending on how these provisions apply to your total income levels.

Retirement Income Scenarios and Tax Impact

While the OBBBA provides relief for many, your benefits may still be taxable if your total income exceeds the existing Social Security taxation thresholds. The table below highlights how various income sources interact with the broader tax framework to determine your final tax outcome:

While these scenarios provide a helpful framework, the reality is that your tax “puzzle” has many moving pieces. The most effective strategies we build for our clients in Central Pennsylvania treat these income streams as a single, unified plan rather than isolated accounts.

Why Structure Matters

As the table illustrates, the OBBBA isn’t a “set it and forget it” tax cut. Whether your benefits are taxed often depends on how your different accounts interact. For example, a well-timed withdrawal from a Roth account versus a traditional IRA could be the difference between staying below a tax threshold or triggering a higher bill.

Because these sources interact within the federal tax system, the impact of the OBBBA varies across households. For our clients in Camp Hill, Harrisburg, and Hershey, we find that the most effective strategies are those that coordinate RMDs, investment dividends, and Social Security as a single, unified plan.

Take the Next Step in Your Retirement Strategy

Understanding how Social Security benefits interact with your other income sources is critical for evaluating long-term financial health. While the OBBBA provides a new framework for potential tax relief, the outcome for your specific household depends on the broader structure of your retirement plan.
