IRS Releases Tax Year 2027 Inflation Adjustments (Rev. Proc. 2026-35): Standard Deduction, Brackets, CTC, Estate & Gift — Returns Filed in 2028

One-sentence takeaway

On November 5, 2026, the IRS issued IR-2026-133 and Revenue Procedure 2026-35, announcing almost 70 inflation-adjusted amounts for tax year 2027—including a joint standard deduction of $33,200, updated marginal brackets (top rate still 37%), a maximum Child Tax Credit of $2,300, and an estate exclusion of $15,480,000—amounts that generally apply to returns filed in 2028, with taxpayers continuing to benefit from the Working Families Tax Cuts (WFTC).

News background

Each fall the IRS publishes the next tax year’s inflation adjustments. For tax year 2027, IR-2026-133 (Nov. 5, 2026) and Rev. Proc. 2026-35 cover rate schedules, the standard deduction, credits, AMT, estate and gift exclusions, §179 expensing, EITC, transportation fringe, health FSA, and the foreign earned income exclusion, among other items.

IRS Chief Executive Officer Frank J. Bisignano emphasized that hardworking taxpayers continue to benefit from the Working Families Tax Cuts, with WFTC credits and deductions increasing with this adjustment—ranging from a higher standard deduction and Child Tax Credit for families to a higher business expensing amount.

Timing: the tax year 2027 figures generally apply to returns filed in 2028. Calendar-year 2027 gift exclusions and 2027 deaths for the estate exclusion follow the calendar-year rules stated in the release. Personal exemptions remain $0 for 2027; that TCJA elimination was made permanent by the WFTC (distinct from any senior deduction added by WFTC).

Cross-border and multi-state angle: the foreign earned income exclusion rises to $137,300; annual gift exclusion to $20,000 (non-citizen spouse $201,000); estate exclusion to $15.48 million. Multi-state filers should refresh 2027 wage withholding, estimated tax, and year-end projections once these federal amounts are locked in—state conformity still varies by state.

Old vs. new

Standard deduction 2027: MFJ $33,200 (up $1,000 from 2026); Single / MFS $16,600; Head of Household $24,925.

Marginal rates 2027 (top still 37%): 37% for Single income over $661,375 (MFJ over $793,650); 35% over $264,550 ($529,100 MFJ); 32% over $208,325 ($416,650 MFJ); 24% over $109,125 ($218,250 MFJ); 22% over $52,025 ($104,050 MFJ); 12% over $12,800 ($25,600 MFJ); 10% at or below those 12% thresholds.

Child Tax Credit: max $2,300 (up $100); refundable portion $1,800 (up $100).

AMT exemption: unmarried $93,000 (phaseout starts $515,950); MFJ $144,700 (phaseout $1,031,900).

Estate / gift: estate exclusion $15,480,000 (was $15,000,000 for 2026 deaths); annual gift exclusion $20,000 (was $19,000); gifts to a non-citizen spouse $201,000 (was $194,000).

Business / other: §179 up to $2,640,000 (was $2,560,000), SUV limit $33,100 (was $32,000); adoption credit up to $18,250 (refundable $5,280); EITC max (3+ children) $8,496; monthly qualified transportation fringe / parking $350; health FSA salary reduction $3,500, carryover max $700; FEIE $137,300 (was $132,900).

Unchanged by indexing: personal exemptions remain 0; Lifetime Learning Credit MAGI phaseout still $80,000–$90,000 ($160,000–$180,000 joint).

Self-check

Wage earners and dual-income households: compare 2027 projected taxable income to the new brackets and standard deduction; decide whether to adjust Form W-4 or estimated payments for 2027 pay periods.

Families with qualifying children: model the $2,300 CTC and $1,800 refundable portion against 2027 income and filing status; confirm qualifying-child tests still met.

High-income / AMT-sensitive filers: refresh AMT exemption and phaseout thresholds ($93,000 / $515,950 unmarried; $144,700 / $1,031,900 MFJ) before locking large capital-gain or incentive timing into 2027.

Estate and gift planners: update lifetime exclusion models to $15.48 million for 2027 deaths and annual exclusion to $20,000 ($201,000 non-citizen spouse); coordinate with state estate/inheritance rules where applicable.

Owners claiming §179, FSA, parking, or FEIE: plug in $2,640,000 §179 / $33,100 SUV, $3,500 health FSA / $700 carryover, $350 monthly fringe, and $137,300 FEIE when building 2027 budgets—especially multi-state and expat filers.

Simplified example

Simplified illustration only—not a projection for any taxpayer and not a promise of any tax result.

Assume a married couple filing jointly with $220,000 of 2027 wages, no itemized deductions above the standard deduction, and two qualifying children.

Standard deduction: they use the 2027 MFJ amount of $33,200 (was $32,200 in 2026)—$1,000 more of income sheltered before brackets apply.

Brackets: taxable income after the standard deduction is about $186,800, so their top marginal rate is 22% for MFJ (22% applies over $104,050; the 24% band starts over $218,250). Tax is still computed layer by layer through the 10%/12%/22% brackets.

Child Tax Credit: maximum credit $2,300 × 2 = $4,600 before phaseouts (refundable portion up to $1,800 per child under the release’s 2027 figures), subject to income and other statutory limits—always recompute with actual Form 1040 worksheets.

Takeaway: inflation indexing alone does not change filing status or credit eligibility tests; it updates the dollar thresholds you should use when forecasting 2027 liability for returns filed in 2028.

Action steps and timeline

Now (November 2026): read IR-2026-133 / Rev. Proc. 2026-35; refresh 2027 cash-flow and estimated-tax models with the new standard deduction, brackets, CTC, AMT, estate/gift, §179, FSA, and FEIE figures.

Late 2026 / early 2027: update payroll withholding, estimated vouchers, and multi-state projections; employers should confirm cafeteria-plan and parking / transit limits for plan years beginning in 2027.

During 2027: track large gifts against the $20,000 annual exclusion; businesses planning equipment purchases should model the $2,640,000 §179 ceiling and SUV limit.

Watch list — still pending as of November 6, 2026: IRS has not yet published 2027 401(k) / IRA contribution limits; do not invent those numbers—revisit when the separate retirement-limit announcement posts.

Early 2028: prepare and file tax year 2027 returns using these inflation-adjusted amounts; keep Rev. Proc. 2026-35 with your workpapers.

FAQ

Q: Do these 2027 amounts change the return I file in spring 2027?

A: Generally no. Tax year 2027 adjustments apply mainly to returns filed in 2028. Your spring 2027 filing is usually for tax year 2026, which uses the prior year’s inflation figures.

Q: Are 2027 401(k) and IRA contribution limits included in Rev. Proc. 2026-35?

A: No. As of November 6, 2026, the IRS has not yet published the separate 2027 retirement contribution limits. Watch for that announcement; do not assume numbers from prior years without confirmation.

Q: Personal exemptions are still zero—did WFTC change that?

A: For tax year 2027, personal exemptions remain 0. The TCJA elimination was made permanent by the Working Families Tax Cuts. (That personal exemption is separate from any senior deduction added by WFTC.)
