How the One Big Beautiful Bill Changes Your Taxes

Tax legislation rarely arrives quietly, and the One Big Beautiful Bill Act is no exception. Signed into law in 2025, the OBBBA makes significant adjustments to the individual tax code that will affect 2026 filings and beyond. Rather than sorting through partisan debate, this guide focuses entirely on the provisions themselves: what they say, how they work mathematically, and what they look like in practice across different household types.

The five provisions drawing the most attention are the exclusion of tip income from federal tax, the exclusion of overtime pay from federal tax, the increased SALT deduction cap of $40,000, the expanded Child Tax Credit of $2,200, and a new $6,000 senior deduction for taxpayers aged 65 and older. Each one is examined below with worked examples at multiple income levels. All examples use hypothetical personas and are illustrative only.

The OBBBA introduces a federal income tax deduction for qualified tip income received by workers in traditionally tipped occupations. This does not eliminate payroll taxes such as Social Security and Medicare on those tips, but it removes the federal income tax bite on qualifying tip amounts, subject to an income phase-out threshold.

The deduction phases out for single filers with modified adjusted gross income (MAGI) above $150,000 and for married filing jointly above $300,000. Workers in tipped industries above those thresholds receive a reduced or no benefit.

Illustrative Example A: Restaurant Server, Single Filer

• Annual wages (base): $22,000
• Annual tip income: $18,000
• Total gross income: $40,000
• Under prior law, all $40,000 was subject to federal income tax. In the 22% bracket (after the standard deduction of $15,000 for single filers in 2026), the taxable income would have been roughly $25,000, producing a federal income tax liability of approximately $2,800 to $3,000 depending on other factors.
• Under the OBBBA, the $18,000 in tip income is deductible. Taxable income after the standard deduction falls to approximately $7,000, dramatically reducing the federal income tax bill.

Illustrative Example B: Hotel Concierge, Married Filing Jointly

• Combined household income: $95,000, including $12,000 in tip income for one spouse
• The tip deduction reduces taxable income by $12,000, which at a 22% marginal rate represents roughly $2,640 in federal tax savings
• Well below the $300,000 phase-out threshold, so the full deduction applies

Workers with relatively modest base wages but significant tip income stand to see the most meaningful percentage reduction in their federal tax liability. It is worth noting that state income tax treatment of tip income varies, and many states have not conformed their tax codes to mirror this federal change.

The OBBBA also allows workers to deduct qualifying overtime compensation from federal taxable income. Overtime here refers to hours worked beyond 40 per week that are compensated at a premium rate under the Fair Labor Standards Act. The same income phase-out thresholds apply: $150,000 for single filers and $300,000 for married filing jointly.

Illustrative Example C: Manufacturing Worker, Married Filing Jointly

• Regular wages: $62,000
• Annual overtime pay: $14,000
• Total income: $76,000
• Standard deduction for married filing jointly in 2026: $30,000 (the OBBBA also permanently extends the higher standard deductions established under the 2017 Tax Cuts and Jobs Act and adjusts them for inflation)
• Under prior law, taxable income would be approximately $46,000. Under the OBBBA, the $14,000 overtime deduction reduces taxable income to roughly $32,000, a reduction that at the 12% marginal bracket represents approximately $1,680 in federal tax savings

Illustrative Example D: Nurse, Single Filer, Higher Overtime

• Regular wages: $72,000
• Annual overtime: $22,000
• Total income: $94,000
• The full $22,000 overtime deduction applies (income is below the $150,000 phase-out)
• At a marginal rate of 22%, this represents approximately $4,840 in federal tax savings
• MAGI is below $150,000, so no phase-out reduction applies

For workers who regularly log substantial overtime hours, this provision could represent one of the more tangible changes in their annual tax picture. Keep in mind that FICA taxes (Social Security and Medicare) still apply to overtime pay, so net savings are limited to the income tax component.

One of the more debated provisions of the prior tax law was the $10,000 cap on the State and Local Tax (SALT) deduction, introduced in 2017. The OBBBA raises that cap to $40,000 for most filers, though it phases down for higher earners. Specifically, the $40,000 cap phases out for taxpayers with MAGI above $500,000, reducing back toward the prior $10,000 limit at higher income levels. The provision is also structured to increase slightly in subsequent years.

Who this matters most for:

• Homeowners in states with high property taxes and/or high state income taxes, including California, New York, New Jersey, Illinois, and Connecticut
• Taxpayers who itemize deductions rather than taking the standard deduction
• Note: If your total itemized deductions including mortgage interest, charitable giving, and SALT do not exceed the standard deduction ($30,000 married filing jointly, $15,000 single in 2026), the increased SALT cap has no practical effect on your return

Illustrative Example E: Homeowner in New Jersey, Married Filing Jointly

• State income tax paid: $12,000
• Property taxes paid: $16,000
• Total SALT: $28,000
• Under the old $10,000 cap, only $10,000 was deductible. Under the OBBBA $40,000 cap, the full $28,000 is deductible (assuming they itemize)
• The additional $18,000 in deductions, at a 22% marginal rate, produces roughly $3,960 in federal tax savings

Illustrative Example F: Homeowner in California, Married Filing Jointly, Higher Income

• State income tax: $30,000
• Property taxes: $14,000
• Total SALT: $44,000
• MAGI: $420,000 (below the $500,000 phase-out threshold, so the full $40,000 cap applies)
• Deductible SALT: $40,000 (previously capped at $10,000)
• Additional deduction of $30,000. At a 32% marginal rate, that represents approximately $9,600 in federal tax savings

For families considering how this fits into their broader retirement tax planning picture, the SALT change can be meaningful when combined with mortgage interest and other itemized deductions.

The Child Tax Credit (CTC) increases to $2,200 per qualifying child under age 17, up from $2,000 under the prior law. The credit begins to phase out at $400,000 of MAGI for married filing jointly and $200,000 for single filers. The refundable portion of the credit (the Additional Child Tax Credit) is also adjusted under the OBBBA, with up to $1,700 potentially refundable for lower-income families depending on earned income.

Illustrative Example G: Family With Two Children, Married Filing Jointly

• Household MAGI: $130,000
• Two qualifying children
• Prior law CTC: $4,000 total ($2,000 x 2)
• OBBBA CTC: $4,400 total ($2,200 x 2)
• Additional benefit: $400 more in tax credits per year

Illustrative Example H: Single Parent, One Child

• MAGI: $48,000
• One qualifying child
• CTC: $2,200 (fully available below the phase-out)
• If federal income tax liability is lower than $2,200, the refundable portion provides additional benefit depending on earned income calculations

The $200 per-child increase is modest rather than transformative for most middle-income families, but it does compound for larger families and adds up across multiple tax years.

One provision that has received comparatively less attention is a new above-the-line deduction of $6,000 available to taxpayers who are 65 or older. This means the deduction is available regardless of whether you itemize, making it accessible to seniors who take the standard deduction. The deduction phases out for higher-income seniors, beginning to reduce at MAGI above $75,000 for single filers and $150,000 for married filing jointly.

This deduction is separate from and in addition to the existing additional standard deduction already available to taxpayers aged 65 and older (which in 2026 is approximately $1,950 for single filers and $1,550 per qualifying spouse for married couples, per standard IRS adjustment schedules).

Illustrative Example I: Retired Couple, Both Over 65, Married Filing Jointly

• Income: Social Security of $36,000 (partially taxable) plus $24,000 in IRA distributions, for a combined gross income of approximately $60,000
• MAGI: approximately $60,000 (below the $150,000 phase-out)
• Both spouses qualify: $6,000 deduction each, totaling $12,000 in additional above-the-line deductions
• At a 12% marginal rate, this represents approximately $1,440 in federal tax savings

Illustrative Example J: Single Retiree, Age 68

• MAGI: $68,000 (Social Security plus pension)
• Below the $75,000 single-filer phase-out threshold
• Full $6,000 deduction available
• At a 22% marginal rate: approximately $1,320 in federal tax savings

For retirees managing Required Minimum Distributions from traditional IRAs or 401(k) plans, this deduction can help offset some of the ordinary income those distributions generate, particularly in the years before higher RMD amounts kick in.

It is worth noting that the phase-out thresholds for this deduction are not indexed to inflation under the current statutory language, meaning their real value erodes slightly over time unless Congress acts to adjust them.

Tax provisions rarely operate in isolation, and the OBBBA is no different. Consider a hypothetical household where multiple changes apply simultaneously.

Illustrative Example K: Combined OBBBA Scenario

• Married couple, both working, one spouse a nurse earning $72,000 regular wages plus $18,000 overtime; the other a restaurant manager earning $55,000 (no tips, no overtime)
• Two children under 17
• Home in New Jersey with $24,000 in combined SALT (property taxes plus state income taxes)
• Combined household MAGI: approximately $145,000

Under the OBBBA, this household could benefit from:

• Overtime deduction: $18,000 deducted from income. At 22%, roughly $3,960 in savings
• SALT cap increase: Full $24,000 SALT deductible (up from $10,000). Additional $14,000 in deductions translates to roughly $3,080 in savings if they itemize
• Child Tax Credit: $4,400 total ($2,200 x 2), up from $4,000, saving an additional $400
• Combined potential federal tax reduction: In the range of $7,000 to $8,000 compared to prior law, depending on the full structure of their return

This example is illustrative only and does not account for all possible deductions, credits, or individual circumstances. Tax outcomes depend on the complete picture of each household's finances.

If you are thinking about how tax changes in 2026 interact with your long-term retirement planning timeline, it may be worth revisiting your contribution strategy and withholding elections in light of any meaningful change in your effective tax rate.

With significant tax legislation comes significant confusion. A few points worth clarifying:

• Payroll taxes are not affected. The tip and overtime exclusions apply only to federal income tax. Social Security and Medicare taxes still apply to all wages, including tips and overtime. Workers should not expect their FICA withholding to change as a result of these provisions.
• State taxes are a separate question. Each state sets its own conformity rules. Some states will automatically conform to federal changes; others will not. Workers in states with income taxes on tips or overtime should not assume state-level relief unless their state legislature enacts conforming legislation.
• The SALT benefit only matters if you itemize. If your total itemized deductions do not exceed your standard deduction, the increased SALT cap provides no benefit. For many households, the higher standard deduction (itself preserved and expanded under the OBBBA) means itemizing remains less advantageous than it might appear.
• The $6,000 senior deduction is not a credit. It reduces taxable income, not the tax bill directly. A $6,000 deduction for someone in the 12% bracket saves $720, not $6,000.
• Income limits apply to most provisions. High earners will see reduced or no benefit from the tip exclusion, overtime exclusion, and senior deduction. The SALT cap increase phases out at $500,000 MAGI.
