It’s been nearly six months since the Republican majority in Congress passed a tax and spending megabill, locking in a historically high estate tax exemption while maintaining the maximum 37% tax bracket.
Relatively few clients have income or wealth high enough to take full advantage of those two provisions, but many retirees will be able to use the legislation's temporary senior bonus deduction of up to $6,000.
As detailed in a new analysis from the Colcom Group, a consulting and accounting firm, the deduction is designed to provide additional tax relief for retirees and near-retirees. It builds upon the long-standing standard deduction for seniors under current law.
“Understanding how these two benefits interact is key to planning effectively over the next four years,” the report warns.
Bonus Deduction Basics
Starting for tax year 2025, taxpayers who are 65 or older by year-end may claim an additional $6,000 deduction per person. Married couples filing jointly may claim $12,000 total if both spouses qualify.
The deduction applies only for tax years 2025 through 2028, the report notes, and is also subject to an income phaseout, with the full bonus being available until modified adjusted gross income reaches $75,000 for a single taxpayer or $150,000 for married joint filers.
Above those thresholds, the deduction phases out at about 6% of modified adjusted gross income over the limit, disappearing entirely around $175,000 for singles and $250,000 for couples.
Does the Benefit Stack?
Importantly, the report states, the bonus deduction is available whether a client itemizes or takes the standard deduction.
“This is important because it makes the bonus broadly accessible, even for taxpayers who itemize due to mortgage interest, charitable giving or other deductions,” the report explains.
Among the “other deductions” category is the longstanding deduction for taxpayers who are 65-plus and/or blind. For tax year 2025, the inflation-adjusted additional standard deduction amounts are $2,000 for qualifying single filers or heads of household and $1,600 per qualifying spouse for married couples filing jointly or separately.
“This existing additional standard deduction only applies if you take the standard deduction,” the report emphasizes. “If you itemize, you don’t get this add-on.”
Combining the Two Deductions
As the report recounts, the summer legislation clarifies that the $6,000 senior bonus deduction is in addition to the current additional standard deduction for seniors.
Eligible seniors, then, may receive the regular standard deduction (or itemized deductions), plus the existing additional standard deduction for taxpayers 65 and older (only if using the standard deduction), plus the senior bonus deduction of $6,000 per person (standard or itemized).
“So in practice, standard-deduction seniors get the biggest stacking effect,” the analysis finds. “They benefit from both senior-related additions. Itemizing seniors still gain meaningful relief via the new bonus, even though they don’t qualify for the older standard-only add-on.”
The deduction amounts may not be large, the report continues, but can have a meaningful effect on a client’s overall financial plan.
“For many retirees, taxable income is driven by a combination of Social Security, pensions, investment income and required minimum distributions,” the report explains. “Reducing taxable income through stacked deductions may lower federal tax owed and potentially reduce how much of Social Security becomes taxable under existing rules.”
Because the senior bonus deduction is temporary, the report concludes, there may be planning opportunities around income timing — especially for taxpayers near the MAGI thresholds.
