Executive Summary:
- New Law, Old Taxes: The recent One Big Beautiful Bill Act (OBBBA) added a deduction for seniors aged 65 or older, but left Social Security benefit taxes fully intact.
- Provisional Income (PI): Taxability depends on PI, calculated by adding your AGI, tax-exempt interest, and 50% of your Social Security benefits.
- The Two Tiers: Up to 50% of benefits are taxed at a PI of $32,000–$44,000 ($25,000–$34,000 for single filers). Above $44,000 ($34,000 single), up to 85% is taxed. These tiers are unindexed for inflation.
- Tax Strategies: Seniors can lower their PI via capital losses, annuities, growth stocks, life insurance, or IRA contributions before filing 2026 returns in 2027.
The new tax law enacted last year—the One Big Beautiful Bill Act (OBBBA)—includes several provisions that may benefit senior citizens, including a brand-new tax deduction for qualified individuals age 65 or older. But one thing hasn’t changed despite the OBBBA: the tax on Social Security retirement benefits remains in full effect. What’s more, the relatively low “tax tiers” triggering this tax haven’t budged in decades!
The basics: The determination of whether you do, or you don’t, owe in come tax on Social Security benefits depends on the amount of your annual “provisional income” (PI). For theses purpose, PI is the total of your AGI, tax-exempt interest income and one-half of the Social Security benefits received. For example, if your AGI is $100,000 and you collect $12,000 in municipal bond income and $16,000 in Social Security benefits, your PI is $120,000 ($100,000 plus $12,000 plus $8,000).
There are two tiers for taxing Social Security benefits. The tax kicks in at modest income levels.
Tier #1: If your PI is between $32,000 and $44,000 ($25,000 and $34,000 for single filers), you must pay tax on the lesser of one-half of your benefits or 50% of the amount by which PI exceeds $32,000 ($25,000 for single filers).
Tier #2: If your PI is above $44,000 ($34,000 for single filers), you must include in taxable income 85% of the amount by which PI exceeds $44,000 ($34,000 for single filers) plus the lesser of the amount determined under the first tier or $6,000 ($4,500 for single filers). However, in no event can the amount exceed 85% of the benefits received.
Caveat: Unlike most other tax law provisions with dollar thresholds, these tiers have never been indexed for inflation. So, each year more taxpayers are potentially exposed to this tax.
It’s often inevitable for senior citizens.
What can you do about it? Plenty. When it is feasible, try to lower your PI below either of the thresholds before the end of the year. Here are several commonly-used ideas to consider.
- Realize capital losses that offset capital gains and other income.
- Invest in long-term growth stock that won’t produce current income.
- Invest in annuities that provide tax-deferred growth.
- Acquire life insurance that will provide protection without tax consequences.
- If you’re eligible, contribute to an IRA or qualified retirement plan.
Timely reminder: Of course, every situation is different. Meet with your clients mid-year to work out a plan that minimizes the tax damages. Remember that they don’t have to pay the tax on Social Security retirement benefits until they file their 2026 tax returns—in 2027.
