The One, Big, Beautiful Bill Act may lower some people’s federal tax bills, but it does not give every taxpayer the same raise. The effect depends on which deductions or credits you qualify for, your income and filing status, and the rest of your tax return. A deduction reduces taxable income; it does not put its full dollar amount in your pocket.
Which federal tax amounts changed for 2025?
The law is Public Law 119-21. The following are federal amounts for tax year 2025—the return generally filed in 2026—not estimates of how much a household will save.
| Provision | 2025 amount | What the figure means |
|---|---|---|
| Standard deduction | $31,500 for married filing jointly; $23,625 for head of household; $15,750 for single or married filing separately | Federal standard deduction amounts by filing status, according to current IRS individual tax guidance. |
| State and local tax (SALT) itemized deduction limit | $40,000; $20,000 for married filing separately | Maximum itemized deduction, reduced for taxpayers above specified modified adjusted gross income thresholds. |
| Child tax credit | Up to $2,200 per eligible child | Maximum credit, subject to eligibility requirements. |
| Qualified tips deduction | Up to $25,000 per return | Deduction subject to occupational, reporting, and income-phaseout rules. |
| Qualified overtime deduction | Up to $12,500 per individual; $25,000 on a joint return | Deduction subject to FLSA qualification and an income phaseout. |
| Additional deduction for eligible seniors | Up to $6,000 per eligible individual | Deduction subject to an income phaseout; available whether the taxpayer itemizes or takes the standard deduction. |
| Qualified passenger-vehicle loan interest | Up to $10,000 | Deduction subject to eligibility and income rules. |
The amounts above come from IRS individual tax guidance and withholding information accessed October 4, 2026, along with IRS guidance on Schedule 1-A and qualified overtime. They are deduction ceilings or a credit maximum—not a forecast of your refund, paycheck, or after-tax income.
Why a deduction is not the same as extra take-home pay
A deduction reduces the amount of income subject to federal income tax, if you qualify and can claim it. Its value depends on your tax situation; a deduction of a given amount does not reduce your tax bill by that same amount. A credit is different: it reduces tax itself, subject to the credit’s rules.

Your actual result also depends on filing status, income, eligible expenses or earnings, other deductions and credits, and whether you use the standard deduction or itemize. The IRS has not published a typical household after-tax gain that can be applied to everyone. Without those personal details, there is no reliable single-dollar answer.
Who may qualify for the tips deduction?
The deduction is for qualified tips—not every payment a worker receives in addition to wages. The IRS says qualifying tips must be voluntary cash or charged tips, reported by the recipient, and earned in an occupation that customarily and regularly received tips by December 31, 2024. Mandatory service charges do not qualify. Special limits also apply to self-employed people and employees of specified service businesses.
Rank #2
The deduction phases out above modified adjusted gross income of $150,000 for most filers and $300,000 for joint filers. Tips remain subject to income and payroll taxes; the IRS made that distinction in its 2025 withholding guidance.
Which overtime pay qualifies?
The overtime deduction covers qualified compensation required under the Fair Labor Standards Act (FLSA), generally the portion paid above a worker’s regular rate. An employer’s use of the word “overtime” on a payslip does not by itself make every premium payment eligible.

The IRS’s qualified-overtime FAQ, updated August 6, 2026, states that directly. For 2026, employers must report qualified overtime separately on Form W-2, box 12, code TT. For 2025, the IRS provided transition relief from separate reporting.
What are the senior and other deduction rules?
Additional deduction for seniors
You must be at least 65 by the end of the tax year to qualify. The deduction phases out above modified adjusted gross income of $75,000 for most filers and $150,000 for joint filers. IRS guidance says it is available whether you itemize or take the standard deduction.
Passenger-vehicle loan interest
The deduction applies only to qualified passenger-vehicle loan interest and is subject to eligibility and income rules. The IRS’s 2026 filing-season guidance identifies the limit, but a taxpayer needs to check the applicable IRS instructions against the vehicle, loan, and household circumstances before claiming it.
Child credit and SALT deduction
The child tax credit is a credit, not a deduction, and its maximum applies only to eligible children and taxpayers who meet the credit’s requirements. The SALT amount is an itemized-deduction limit, not a payment from the government; its benefit depends on itemizing and the applicable income-based reduction.
How to claim a deduction or check your withholding
Claim the benefit on a federal return
- Identify the tax year and the provision that may apply to you. For the 2025 return, review the IRS instructions for the relevant deduction and its eligibility and documentation requirements.
- Complete Schedule 1-A for applicable deductions and file it with Form 1040, 1040-SR, or 1040-NR, as appropriate. The IRS announced the Schedule 1-A process on March 2, 2026.
- Compare the completed return with your withholding and estimated payments. A refund is generally the result of payments exceeding final tax liability; it is not automatically a separate bonus or the amount of a deduction.
Adjust paycheck withholding for a coming year
Use the IRS Tax Withholding Estimator if you want to consider how the changes affect withholding for taxes owed the following year. The IRS announced on March 12, 2026, that the estimator had been updated to include tips, overtime, vehicle-loan interest, the senior deduction, and other changes. It estimates withholding; it does not replace filing a return or determine eligibility conclusively.
Some changes applied retroactively to the start of 2025, so withholding or estimated payments may not have reflected them during that year. That can affect the size of a refund or balance due, but a changed refund does not by itself show how much your final tax liability changed. The rules discussed here concern federal individual income tax; they do not establish how any state treats these items. For complex income, eligibility, or filing situations, a tax professional can assess the return using your records.
