IRS raises 2027 tax brackets and the standard deduction

The Internal Revenue Service released its 2027 federal income tax brackets on Thursday, November 5, along with higher standard deductions and a larger maximum child tax credit. The seven rates still run from 10% to 37%. What moves is the amount of taxable income that fits within each bracket.

For most individuals, the updated amounts apply to income earned in calendar year 2027 and reported on returns generally filed in 2028. The federal returns most households will file in spring 2027 cover tax year 2026 and use the 2026 figures. The November announcement looks a year ahead of that filing season.

What did the IRS change for 2027?

The agency's November announcement summarizes annual adjustments to nearly 70 provisions. The detailed Revenue Procedure 2026-35 sets out the full rate tables, including schedules for heads of household and married people filing separately. It also gives the amounts used to calculate credits and other deductions.

The standard deduction is a dollar amount that generally reduces income subject to federal income tax for people who take it instead of itemizing deductions. For a single filer, the basic amount goes from $16,100 in 2026 to $16,600 in 2027. The joint amount rises from $32,200 to $33,200. The head-of-household amount moves from $24,150 to $24,925, an increase of $775. The 2027 joint amount also appears in the schedule for qualifying surviving spouses.

A $500 increase in the deduction shelters $500 more income for a single filer who takes it. The change in that person's federal income tax depends on which rates would have applied to those dollars and what else is on the return. Two households with identical wages can still report different taxable incomes because of filing status, adjustments and deductions. The headline deduction is the basic amount. Separate provisions address filers who are at least 65 or blind and people who can be claimed as someone else's dependent.

The IRS attributed the higher amounts to its annual inflation adjustments under current law. The new figures build on provisions in the 2025 tax law, which the IRS calls the Working Families Tax Cuts. The law and the annual adjustment do different jobs. Congress sets the tax rules. The IRS publishes updated dollar amounts for the provisions that are indexed. For broader price context, NewsCubby has covered the September consumer price report and the separate personal consumption expenditures measure. A monthly or year-over-year headline inflation rate should not be applied directly to every tax figure.

Where do the 2027 tax brackets start?

The IRS lists the following federal thresholds for ordinary taxable income. The first figure in each line is for a single filer. The second is for a married couple filing jointly.

• 10% on taxable income through $12,800 for singles and $25,600 for joint filers.

• 12% on the portion above $12,800 and $25,600, respectively, up to the next threshold.

• 22% on the portion above $52,025 and $104,050.

• 24% on the portion above $109,125 and $218,250.

• 32% on the portion above $208,325 and $416,650.

• 35% on the portion above $264,550 and $529,100.

• 37% on the portion above $661,375 and $793,650.

The starting point is taxable income, which generally comes after relevant deductions, rather than the full salary printed on a job offer or the total amount deposited in a bank account. The schedules for other filing statuses are in the revenue procedure. Certain income, such as qualifying long-term capital gains, is subject to separate rules and should not be run through this table as though all income were wages.

The IRS explanation of marginal tax rates shows why crossing a bracket does not push all income into a higher rate. Consider a simplified example. A single filer with $70,000 of income, the standard deduction and no other adjustments would have $53,400 in taxable income in 2027. The first $12,800 would fall in the 10% bracket. The next $39,225 would fall in the 12% bracket. Only the remaining $1,375 would fall in the 22% bracket. The calculation is illustrative and leaves out credits and other taxes.

The same distinction matters when comparing this year with next. For someone whose taxable income stays constant, a threshold that moves up can place more of the same income in a lower bracket. For someone whose pay, filing status or deductions change, the result depends on all of those changes. A bracket adjustment also does not say how much Social Security or Medicare tax will appear on a pay stub. The 2027 Social Security cost-of-living adjustment was a separate federal announcement with a different purpose.

How does the larger child tax credit work?

A deduction and a credit enter the calculation at different points. The standard deduction reduces taxable income. A credit generally reduces the income tax calculated on that income. The 2027 maximum child tax credit is $2,300 per qualifying child, up $100. The maximum amount that may be refundable is $1,800 per qualifying child, also up $100. The refundable component can benefit eligible filers even when their federal income tax is too low to use all of the ordinary credit. It is part of the credit structure and is subject to separate conditions.

The maximum is not an amount every family receives. The IRS child tax credit guide explains rules involving age, relationship, residency, identification numbers and income. A child generally must be under 17 at the end of the tax year for the child tax credit. Different rules can apply to other dependents. The relevant tax-year instructions explain how to calculate the amount available to a household and how much, if any, is refundable.

The earned income tax credit is a separate benefit with its own rules. The IRS lists a 2027 maximum of $8,496 for qualifying taxpayers with three or more qualifying children, compared with $8,231 in 2026. The detailed tables give different amounts for smaller families and eligible workers without a qualifying child. They also show the income ranges where the benefit starts to fall. The announced maximum describes one eligibility category, not a universal payment or a second child tax credit.

Which other dollar amounts moved?

The same release raises the cap for qualified adoption expenses to $18,250 in 2027, from $17,670 in 2026. Up to $5,280 of the credit may be refundable in 2027. The detailed guidance also specifies a separate rule for qualifying adoptions of children with special needs. Both provisions are part of the adoption credit, which has its own income limits. They do not change the child tax credit amount.

The guidance also sets a $3,500 limit on voluntary employee salary reductions for a health flexible spending arrangement in 2027. If the employer's plan permits unused amounts to carry over, the federal carryover ceiling rises to $700. That allowance concerns payroll contributions to an eligible workplace benefit. It is distinct from the standard deduction claimed on a federal return. The IRS release covers the amounts that are changing, while individual benefit plans determine which options participants can use.

What to watch as the new tax year approaches

The 2027 brackets will be relevant to wages and other taxable income during 2027. Federal income tax withheld from a paycheck is a prepayment toward the annual calculation. A refund or balance due also depends on how much was paid during the year, including withholding and estimated payments, as well as the tax and credits shown on the return. A higher standard deduction cannot by itself establish the size of a future refund.

The IRS says an employer's withholding calculation depends on wages and information from the employee's Form W-4. An annual bracket table and a weekly or biweekly pay stub therefore answer different questions. The bracket table describes how income tax is calculated on annual taxable income. The pay stub shows the amount collected for that pay period, which will be credited toward the eventual calculation.

The next material documents are the 2027 withholding tables and tax-year forms and instructions that turn the annual adjustments into payroll and filing calculations. For the upcoming filing season, the year printed on the return remains the simplest way to keep the two sets of figures straight. A 2026 return generally filed in 2027 uses the 2026 amounts. The standard deduction, brackets and credits announced November 5 generally belong to the 2027 return filed in 2028.
