How Does the OBBBA Senior Deduction Work for Business Owners Over 65?
Last reviewed: July 2026
The OBBBA Senior Deduction gives business owners over 65 up to $6,000 per person through 2028, but the phase-out starting at $75,000 MAGI single and $150,000 joint puts it out of reach for many. For a business owner over 65 in Harford County, the real opportunity is managing your income strategically across a four-year window so you actually qualify.

About the Author: Jeff Judge, CFP®, AEP®, ChFC®, CLU® is Managing Partner of Chesapeake Financial Planners in Forest Hill, Maryland. He has been helping families and business owners in Harford County and the Baltimore metro area navigate tax-aware retirement planning since earning his CFP® certification in 2013, by using Chesapeake Financial Planners’ signature process, the R.U.D.D.E.R. method™. Jeff sees the same pattern every year: business owners over 65 who could claim this deduction lose it because nobody is watching their MAGI until the return is already being filed. As Jeff puts it: "A deduction with a four-year sunset and an income phase-out is basically a reward for owners who plan their MAGI in October — by the time most discover it exists, they have already lost the year where it would have paid off most."
What the OBBBA Senior Deduction Is and Who Qualifies
The OBBBA Senior Deduction is a $6,000 deduction available to any taxpayer who reaches age 65 by the end of the tax year, created when the One Big Beautiful Bill Act was signed into law in 2025. It is not a credit and it is not the extra standard deduction amount that seniors already received. It is a separate, additional deduction layered on top of whatever you were already taking, and it runs only through tax year 2028.
The qualification rules are simpler than most tax provisions. You must be 65 or older by year-end, you must have a Social Security number, and your modified adjusted gross income must fall under the phase-out ceiling. According to the IRS, the deduction is available whether you itemize or claim the standard deduction. That detail matters enormously for business owners, because many high earners itemize and would otherwise assume a new deduction wouldn't reach them.
Does the Senior Deduction Replace the Standard Deduction?
No. The OBBBA Senior Deduction sits on top of the standard deduction and the existing age-65 additional standard deduction. For 2026 the standard deduction figures published by the IRS continue to adjust for inflation, and the senior deduction adds to that base rather than replacing any part of it. A married couple where both spouses are 65 or older could claim $12,000 from this provision alone, separate from everything else on their return.
I often tell clients to think of it as found money with an expiration date. The deduction was designed to sunset after 2028, so the window to use it is fixed. Waiting until you happen to file does not extend it.
How the Income Phase-Out Actually Works for Business Owners
The phase-out is where business owners get tripped up. The deduction begins shrinking once modified adjusted gross income crosses $75,000 for single filers and $150,000 for joint filers, and it disappears completely at $175,000 single and $250,000 joint. Inside that band, the deduction reduces gradually rather than vanishing at a single dollar.
For a W-2 retiree with a fixed pension and Social Security, MAGI is predictable. For a business owner, it is anything but. Distributions, retained earnings paid out as compensation, a strong sales year, a one-time asset sale, or a Roth conversion can all push MAGI across the line without warning. That volatility is the core planning problem.
| Filing status | Phase-out begins (MAGI) | Fully phased out (MAGI) | Maximum deduction |
|---|---|---|---|
| Single, 65+ | $75,000 | $175,000 | $6,000 |
| Married filing jointly, both 65+ | $150,000 | $250,000 | $12,000 |
| Married filing jointly, one spouse 65+ | $150,000 | $250,000 | $6,000 |
What Counts Toward MAGI for This Deduction?
Modified adjusted gross income for this provision starts with your adjusted gross income and adds back certain foreign-earned income exclusions, which rarely apply to a Harford County business owner. In practice, your AGI is your MAGI for nearly everyone reading this. That means the levers you control are the ones that move AGI: how you pay yourself, when you take distributions, and how much you defer into qualified retirement accounts. The IRS definition of modified adjusted gross income confirms the add-backs are narrow for domestic filers.
This is the part where a self-contained answer matters most. If your AGI lands at $160,000 as a single filer, your deduction is already zero. If you can move $90,000 of that income off this year's return through legitimate deferral, you may recover the full $6,000. I've watched a single Roth-versus-traditional decision swing a client's eligibility by the entire deduction amount.
Why Roth Contributions Are the Best Lever for Staying Under the Threshold
Roth contributions are the cleanest tool for managing MAGI around this deduction, because the relationship is direct: every dollar you route into a traditional pre-tax account lowers your AGI today, while Roth dollars do not. That sounds like it argues against Roth. It doesn't, and here's why the timing flips for owners over 65.
If you are already under the phase-out threshold, Roth contributions cost you nothing in deduction eligibility and lock in tax-free growth for the rest of your life. If you are sitting just above the threshold, a traditional pre-tax contribution can pull your MAGI back under the line and unlock the senior deduction. The decision is situational, and the right answer depends on exactly how far above or below the threshold you are.
According to Fidelity, the contribution decision for high earners increasingly hinges on managing taxable income bands rather than chasing the largest current-year deduction. For business owners over 65, the OBBBA window adds a fourth band to watch.
Should a Business Owner Over 65 Choose Roth or Traditional Contributions?
It depends on where your MAGI sits relative to the phase-out. If your projected MAGI is comfortably below $75,000 single or $150,000 joint, choose Roth and bank tax-free growth without sacrificing the deduction. If your MAGI is inside the phase-out band, a traditional pre-tax contribution may buy back part or all of the $6,000 deduction, making the pre-tax route worth more this year. Run the numbers before December, not in April.
My view here is blunt. Most business owners optimize the wrong thing. They obsess over the size of a single year's deduction and ignore the four-year arc of this provision, where coordinating Roth and traditional contributions across 2026, 2027, and 2028 can recover the deduction in multiple years rather than one.
How Solo 401(k) and Retirement Plan Timing Affects Your MAGI
For owner-only businesses, the Solo 401(k) is the most powerful MAGI lever available, because it lets a single owner contribute both as the employee and as the employer. That dual capacity means a profitable year can be partially shifted off your AGI in amounts no IRA can match. According to the IRS retirement plan contribution limits, 401(k) elective deferrals and the additional age-50-plus catch-up contributions adjust annually, and owners 60 to 63 may qualify for an enhanced catch-up under SECURE 2.0.
Here is the strategic point. A traditional (pre-tax) Solo 401(k) contribution directly reduces AGI, which directly reduces MAGI, which can move you under the OBBBA phase-out threshold. For a business owner whose income would otherwise sit at $90,000 as a single filer, a large enough pre-tax deferral can drop MAGI under $75,000 and restore the full senior deduction.
Can a Solo 401(k) Contribution Make Me Eligible for the Senior Deduction?
Yes, in many cases. A pre-tax Solo 401(k) contribution lowers your adjusted gross income dollar for dollar, and because MAGI for this deduction closely tracks AGI, the deferral can pull you below the $75,000 single or $150,000 joint phase-out floor. The exact amount depends on your business income, your age-based contribution limit, and how close to the threshold you started.
Timing is the trap. Employee deferral elections generally need to happen before year-end, while employer contributions can often be made up to the business tax filing deadline. I've seen owners discover the senior deduction in March, only to learn the deferral election that would have saved it expired in December. The Department of Labor guidance on retirement plans reinforces that contribution mechanics and deadlines are strict.
What Business Owners in Harford County Should Do Before 2028
Chesapeake Financial Planners works with business owners across Forest Hill, Bel Air, and the broader Harford County area, and the OBBBA Senior Deduction has become a recurring conversation in our office since the law passed. The local pattern is consistent: successful owners over 65 in Maryland tend to have income that floats near or above the phase-out band, which makes proactive planning the difference between claiming $6,000 and claiming nothing.
The action steps are concrete. First, project your MAGI for the full year by autumn, not at filing. Second, decide on Roth versus traditional contributions based on where that projection lands relative to your threshold. Third, set your Solo 401(k) deferral election before December if a pre-tax contribution would pull you under the line. Fourth, repeat the exercise in 2027 and 2028, because the deduction is available in each of those years independently.
For a Maryland business owner, state tax treatment adds another layer worth reviewing, since Maryland conforms to some federal provisions and not others. According to the Comptroller of Maryland, state and local income taxes interact with your federal AGI, so a planning move that helps federally may shift your Maryland liability in ways worth modeling.
Why Does Geography Matter for This Deduction?
Geography matters because state conformity and your local cost of doing business shape your final MAGI. A business owner near Bel Air pays Maryland state income tax and a Harford County local income tax on top of federal tax, which means your effective marginal rate is higher than the federal rate alone. That higher rate makes a pre-tax deferral that recovers the senior deduction worth even more in real dollars to a Maryland resident than to someone in a no-income-tax state.
This is exactly the kind of situation where sitting across the table from an advisor who knows both the federal provision and Maryland's treatment changes the outcome. I've built these projections for Harford County owners and the recurring lesson is that the deduction is rarely lost on purpose. It is lost because no one looked until the window had closed.
How the R.U.D.D.E.R. Method™ Applies to This Four-Year Window
The R.U.D.D.E.R. Method™ is Chesapeake Financial Planners' six-step planning process: Review and Recognize, Uncover and Understand, Design and Develop, Discuss and Decide, Execute and Empower, and Reassess and Refine. The OBBBA Senior Deduction is a near-perfect illustration of why a repeatable process beats a one-time tax move.
You Review and Recognize that the deduction exists and that your income may put it at risk. You Uncover and Understand exactly where your MAGI is projected to land. You Design and Develop a contribution and distribution plan to manage that number. You Discuss and Decide on Roth versus traditional and how much to defer. You Execute and Empower by making the elections before the deadlines. Then, because this is a four-year provision, you Reassess and Refine every year through 2028.
How Often Should I Revisit This Plan?
At least once a year, ideally each autumn before year-end deadlines close. Because the OBBBA Senior Deduction is available separately in 2026, 2027, and 2028, each year is a fresh opportunity and a fresh risk. A strong sales year, a one-time asset sale, or a Roth conversion can push your MAGI over the threshold in any single year, so the plan that worked last year may need adjustment this year. Annual review is the safeguard.
Frequently Asked Questions
What is the OBBBA Senior Deduction?
The OBBBA Senior Deduction is a $6,000 federal tax deduction for individuals age 65 and older, created by the One Big Beautiful Bill Act for tax years 2025 through 2028. It is separate from the standard deduction and the existing age-65 additional amount. Married couples where both spouses are 65 or older can claim $12,000 combined.
Who qualifies for the OBBBA Senior Deduction?
You qualify if you are 65 or older by the end of the tax year, have a valid Social Security number, and your modified adjusted gross income falls below the phase-out ceiling. The deduction begins phasing out at $75,000 MAGI for single filers and $150,000 for joint filers, and disappears entirely at $175,000 single and $250,000 joint.
How does the income phase-out work for the senior deduction?
The deduction shrinks gradually as your modified adjusted gross income rises through the phase-out band rather than cutting off at a single dollar amount. For single filers it phases out between $75,000 and $175,000 of MAGI, and for joint filers between $150,000 and $250,000. Inside that band you receive a partial deduction.
Can a Solo 401(k) contribution help me qualify?
Yes, in many cases. A pre-tax Solo 401(k) contribution lowers your adjusted gross income dollar for dollar, and because MAGI for this deduction closely tracks AGI, the deferral can pull your income below the phase-out floor. The right contribution amount depends on your business income and your age-based contribution limit, so model it before year-end.
Should business owners over 65 use Roth or traditional contributions?
It depends on where your MAGI sits relative to the threshold. If your income is comfortably below the phase-out floor, Roth contributions preserve the deduction while locking in tax-free growth. If your income is inside the phase-out band, a traditional pre-tax contribution can buy back part or all of the $6,000 deduction. Run the projection before December.
Does the senior deduction expire?
Yes. The OBBBA Senior Deduction was created as a temporary provision and is available only for tax years 2025 through 2028 under current law. Each of those years is a separate opportunity, so a business owner who manages MAGI successfully could claim the deduction in multiple years. After 2028 the provision sunsets unless Congress extends it.
Do I have to itemize to claim the OBBBA Senior Deduction?
No. The OBBBA Senior Deduction is available whether you take the standard deduction or itemize, which makes it especially valuable for business owners who already itemize and might assume a new deduction wouldn't reach them. It stacks on top of your existing deductions rather than competing with them, so you keep it either way.
How does Maryland state tax affect this deduction?
The OBBBA Senior Deduction is a federal provision, so it directly reduces your federal taxable income. Maryland conforms to some federal provisions and not others, and Harford County residents also pay a local income tax tied to state taxable income. A planning move that helps federally may shift your Maryland liability, so model both before acting.
