The 2025 federal tax brackets carry two changes before you get to the rate tables. IRS Rev. Proc. 2024-40 set the inflation-adjusted standard deduction at $15,000 for single filers and $30,000 for married couples filing jointly, up from $14,600 and $29,200 in 2024. Then the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, pushed both figures higher, to $15,750 and $31,500.
Both increases change where millions of clients land before the marginal rates even apply. The seven U.S. federal income tax rates are unchanged from 2024: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Three new above-the-line deductions under OBBBA give qualifying taxpayers additional ways to reduce taxable income before the current federal tax brackets kick in.
This guide covers the complete 2025 federal tax bracket tables for all filing statuses, how the OBBBA deductions interact with them, and the specific threshold crossings that matter most for planning.
The 2025 federal tax tables below apply to income earned in 2025, reported on returns filed in 2026. All figures are per IRS Rev. Proc. 2024-40 and apply to taxable income after the standard deduction or itemized deductions.

Standard deduction for single filers in 2025: $15,750. That is the OBBBA-updated figure, up from $15,000 under the pre-OBBBA inflation adjustment and up from $14,600 in 2024.
Married filing separately uses these same thresholds with one exception: the top federal tax rate of 37% applies above $375,800 rather than $626,350.
Source: IRS Rev. Proc. 2024-40. Applies to combined taxable income. Also applies to qualifying surviving spouses.
Standard deduction for joint filers in 2025: $31,500. That is up from $30,000 under the pre-OBBBA inflation figure, and up from $29,200 in 2024.
The MFJ structure builds in what practitioners call the marriage bonus. Joint thresholds are roughly double the single thresholds at every tier, meaning two-income households rarely face a marriage penalty in the ordinary income bracket structure.
Head of household provides wider lower brackets than single status, reflecting the higher costs of maintaining a household with dependents. The standard deduction for HOH filers in 2025 is $23,625.
The 22% bracket begins at $64,851 for head of household filers, compared to $48,476 for single filers, and the top 37% rate applies above $626,350. Full thresholds are in IRS Rev. Proc. 2024-40, Table 3.
A single client with $120,000 of taxable income lands in the 24% bracket. What they typically assume is that they owe $28,800. What they actually owe is closer to $20,200.
The gap comes from how progressive taxation works. The 10% rate applies only to the first $11,925, the 12% rate covers the next $36,550, and the 22% rate runs from $48,476 to $103,350. Only the income between $103,351 and $120,000 actually hits the 24% rate.
Your marginal federal tax rate is the rate on your last dollar of income, the highest bracket you reach. Your effective federal tax rate (total tax divided by total taxable income) tells you what percentage actually left the account. For most clients in the 22% and 24% brackets, effective rates run between 12% and 17%.
This distinction drives almost every "am I in a good situation?" conversation. It also shapes how you set federal tax withholding on a W-4, whether a year-end bonus meaningfully crosses a threshold, and how to frame Roth conversion opportunities. Getting the explanation right, quickly, is part of what clients pay for.
The One Big Beautiful Bill Act (Pub. L. 119-21) made changes that directly affect where clients land in the bracket tables. None of them change the marginal rates, but all of them can change which bracket a client actually reaches.
IRS Rev. Proc. 2024-40 had already set the inflation-adjusted 2025 standard deduction at $15,000 (single) and $30,000 (MFJ). OBBBA added $750 and $1,500 on top of those figures, respectively.
For a single client in the 22% bracket, that additional $750 deduction saves $165. Modest on its own, but worth communicating clearly when clients ask what the law actually changed for them.
Qualifying employees can deduct up to $12,500 of overtime pay (single) or $25,000 (joint) from gross income before the bracket calculation. This is an above-the-line deduction, meaning it reduces AGI rather than just taxable income.
The deduction phases out at a 10% rate above $150,000 AGI (single) or $300,000 (joint), per IRS Fact Sheet FS-2025-03. It is available through tax year 2028.
Certain service industry employees can deduct reported tip income. The same income limits apply: the deduction phases out above $150,000 AGI (single) or $300,000 (joint) at a 10% rate. For clients in food service, hospitality, or related trades, it can still meaningfully reduce their bracket position for qualifying income, and it also expires after 2028.
Taxpayers age 65 and older may claim an extra $6,000 deduction, with a phase-out beginning at $75,000 AGI (single) or $150,000 AGI (joint) at a 6% rate, per IRS FS-2025-03. This stacks with the existing additional standard deduction amounts: $2,000 for single seniors 65 and older and $1,600 per qualifying spouse for joint filers.
The deduction is available for tax years 2025 through 2028. For retired clients relying heavily on Social Security and modest investment income, the combined effect can still drop taxable income by several thousand dollars before the rate tables apply.
Federal capital gains tax rates don't follow the ordinary income bracket table. They run on their own thresholds, and the misalignment trips up clients regularly.

The 0% rate is worth flagging for any client whose taxable income stays below $48,350, particularly retirees drawing down accounts or clients timing asset sales. A client in the 12% ordinary income bracket may owe nothing on long-term capital gains if taxable income stays under that threshold.
Two additional layers sit above the capital gains rate for high-income clients. The net investment income tax under Section 1411 adds 3.8% on investment income for those above $200,000 (single) or $250,000 (MFJ) in modified AGI. The additional Medicare tax adds 0.9% on wages and self-employment income above those same thresholds. Neither appears in the bracket tables, but both show up in the final liability calculation.
When a client's situation stacks capital gains alongside ordinary income near the NIIT threshold, Bizora's AI Assistant surfaces the Section 1411 interaction, the basis rules, and the holding period requirements.

Not every crossing on the bracket table drives planning decisions equally. Three specific thresholds come up in client conversations far more than the rest.
This is the most common threshold for Roth conversion planning. Single filers with taxable income below $48,475 have room to convert traditional IRA or 401(k) balances at the 12% rate.
Every dollar converted above that threshold tips into the 22% bracket, a 10-percentage-point difference that compounds meaningfully over time. For clients in their late 50s or early 60s with modest earned income and significant pre-tax retirement balances, this corridor is often the most valuable planning window they have.
For pass-through business owners using the Section 199A deduction, this threshold matters twice: once as a bracket crossing, and once because $197,300 falls below the phase-in range where W-2 wage and qualified property limitations begin to apply. Bizora's analysis of the Section 199A deduction and its current-law status covers how QBI interacts with these thresholds in depth.
OBBBA permanently repealed the pre-TCJA Pease limitation on itemized deductions for most taxpayers. For those in the 37% bracket, a new restriction under Section 70111 takes effect starting in tax year 2026, reducing the effective tax benefit of itemized deductions by approximately 5.4% (technically 2/37 of the lesser of total itemized deductions or income above the 37% threshold, per Pub. L. 119-21).
For clients approaching this bracket in 2025, the timing matters. The restriction does not apply until 2026, so 2025 itemized deductions still receive their full benefit at the 37% rate. That makes 2025 the last year to claim a full deduction at that rate, and fourth-quarter deduction decisions more consequential than in prior years.
IRS Rev. Proc. 2025-32, released October 9, 2025 via IR-2025-103, published the 2026 inflation-adjusted bracket thresholds. The seven rates stay the same, but the single 37% threshold rises to $640,600 (from $626,350 in 2025), the standard deduction increases to $16,100 (single) and $32,200 (MFJ), and the AMT exemption for singles rises to $90,100.
OBBBA also changed the AMT mechanics starting in 2026. The exemption phaseout threshold drops from $626,350 to $500,000 for single filers, and the phaseout rate doubles from 25% to 50%. Clients in the $500,000 to $700,000 income range who escaped AMT exposure in 2025 may not in 2026.
For clients near threshold crossings right now, the 2026 figures are available for modeling today. Year-end income timing, deduction acceleration, and Roth conversion sizing all benefit from knowing next year's numbers before December 31.
The 2025 bracket structure is clean on paper: seven rates, inflation-adjusted thresholds, no rate changes from prior years. What's different is the deduction layer. OBBBA's standard deduction increase and three new above-the-line deductions (all with phase-outs and 2028 sunsets) change where clients actually land in the tables before you reach the rate calculation.
For routine client conversations, the effective vs. marginal distinction does most of the work. For planning-driven conversations (Roth conversions, capital gains timing, NIIT exposure, 199A phase-ins, or the 2026 itemized deduction restriction), the specific threshold crossings matter more than the rates themselves.

The seven 2025 federal income tax rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%, per IRS Rev. Proc. 2024-40. The 37% rate applies to taxable income above $626,350 for single filers and $751,600 for married couples filing jointly. All thresholds apply to taxable income after the standard deduction or itemized deductions.
Your marginal federal tax rate is the rate on your last dollar of taxable income, the highest bracket you reach. Your effective federal tax rate is total tax divided by total taxable income, your actual average rate. Because lower income tiers are taxed at lower rates, the effective rate is always lower than the marginal rate. A single filer with $120,000 in taxable income has a 24% marginal rate and roughly a 17% effective rate.
Your bracket depends on your taxable income (adjusted gross income minus deductions) and your filing status. For single filers, the 22% bracket begins at $48,476; for married filing jointly, it begins at $96,951. Match your taxable income to the table for your filing status, and the highest bracket you reach is your marginal federal tax rate.
OBBBA did not change the seven marginal rates or their thresholds. It increased the 2025 standard deduction to $15,750 (single) and $31,500 (MFJ), and added above-the-line deductions for qualifying overtime income (up to $12,500 single / $25,000 joint), tip income for eligible service workers, and an additional $6,000 senior deduction for taxpayers 65 and older. All three new deductions phase out above $150,000 AGI (single) / $300,000 (joint) and expire after tax year 2028.
IRS Rev. Proc. 2025-32, released October 9, 2025 via IR-2025-103, published the 2026 brackets. The seven rates remain the same, but thresholds move upward for inflation. The 37% bracket begins at $640,600 for single filers (up from $626,350 in 2025), and the standard deduction increases to $16,100 for single filers and $32,200 for joint filers.
Long-term capital gains are taxed at 0%, 15%, or 20% under a separate rate structure from ordinary income. The 0% rate applies to single filers with taxable income up to $48,350. The 20% rate begins above $533,400 (single) or $600,050 (MFJ). High-income taxpayers may also owe the 3.8% net investment income tax under Section 1411, which applies above $200,000 (single) or $250,000 (MFJ) in modified AGI.
The IRS adjusts bracket thresholds annually for inflation using the Chained Consumer Price Index (C-CPI-U) to prevent bracket creep, where inflation-driven nominal income increases would otherwise push taxpayers into higher brackets without any real gain in purchasing power. The 2025 thresholds rose approximately 2.8% from 2024. Annual adjustments are published each fall in a Revenue Procedure.
