The Internal Revenue Service released the federal inflation adjustments for tax year 2027 on November 5, 2026. Revenue Procedure 2026-35 establishes updated income tax brackets, standard deductions, capital gains thresholds, Section 199A limits, Section 179 expensing amounts, estate and gift tax exclusions, and numerous other provisions.
These adjustments affect income earned during 2027, generally reported on federal income tax returns filed in 2028. They do not replace the 2026 rules used for returns filed during 2027.
For higher income taxpayers and business owners, the most useful changes are not necessarily the small increases in the standard deduction. The larger planning questions involve when income is recognized, how business deductions interact with marginal tax brackets, whether the Section 199A limitations apply, and how federal and California taxable income may differ.
Key takeaway:
For 2027, the standard deduction increases to $33,200 for married couples filing jointly and $16,600 for single filers. The highest 37% federal tax bracket begins above $793,650 for married couples filing jointly and $661,375 for single taxpayers.
The Section 179 maximum increases to $2.64 million, the Section 199A threshold for joint filers increases to $416,600, and the federal estate tax basic exclusion reaches $15.48 million.
2027 Federal Income Tax Brackets
The federal individual income tax rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Revenue Procedure 2026-35 adjusts the income thresholds for inflation.
The following table shows the taxable income ranges for single taxpayers and married couples filing jointly.
| Federal rate | Single taxpayers | Married filing jointly |
|---|---|---|
| 10% | Up to $12,800 | Up to $25,600 |
| 12% | Over $12,800 to $52,025 | Over $25,600 to $104,050 |
| 22% | Over $52,025 to $109,125 | Over $104,050 to $218,250 |
| 24% | Over $109,125 to $208,325 | Over $218,250 to $416,650 |
| 32% | Over $208,325 to $264,550 | Over $416,650 to $529,100 |
| 35% | Over $264,550 to $661,375 | Over $529,100 to $793,650 |
| 37% | Over $661,375 | Over $793,650 |
These thresholds apply to taxable income, not gross income or adjusted gross income. Taxable income is generally calculated after the applicable deductions and other adjustments.
A taxpayer reaching the 37% bracket does not pay 37% on every dollar of taxable income. The 37% rate applies only to taxable income within that marginal bracket.
2027 Standard Deduction Amounts
The standard deduction increases for every individual filing status.
| Filing status | 2026 | 2027 |
|---|---|---|
| Married filing jointly | $32,200 | $33,200 |
| Single | $16,100 | $16,600 |
| Married filing separately | $16,100 | $16,600 |
| Head of household | $24,150 | $24,925 |
These figures are the basic standard deduction amounts. Additional standard deductions may be available for eligible taxpayers who are age 65 or older or blind.
The separate enhanced senior deduction enacted under Public Law 119-21 is not the same as the additional standard deduction for age or blindness. It has its own eligibility requirements, income phaseout, and statutory expiration after 2028.
Taxpayers should compare the standard deduction with allowable itemized deductions, including the applicable state and local tax limitation, mortgage interest, charitable contributions, and other qualifying amounts.
For comparison with the prior year, see my 2026 IRS inflation adjustment guide.
2027 Capital Gains Tax Brackets
Long term capital gains and qualified dividends generally retain the preferential federal rates of 0%, 15%, and 20%, subject to the applicable rules.
For 2027, the taxable income thresholds are:
| Filing status | Top of 0% range | Top of 15% range |
|---|---|---|
| Married filing jointly | $102,100 | $633,600 |
| Single | $51,050 | $563,200 |
| Head of household | $68,350 | $598,400 |
| Married filing separately | $51,050 | $316,800 |
Capital gains above the applicable 15% breakpoint generally fall into the 20% rate category, subject to the character of the gain and special statutory rules.
These thresholds are based on taxable income that includes the gain, rather than the capital gain amount considered independently.
Certain depreciation recapture and other specially classified gains can be subject to different federal rates. The additional 3.8% net investment income tax may also apply to qualifying investment income when the taxpayer meets the separate statutory requirements.
Why Capital Gain Timing Matters
A taxpayer considering the sale of appreciated stock, an investment property, or an ownership interest in a business should evaluate the entire expected income for the year of sale.
Other income, deductions, suspended losses, installment reporting, and the nature of the asset can affect the federal tax cost.
The higher 2027 inflation adjusted breakpoints do not automatically mean that postponing a sale until 2027 is advantageous. Changes in market value, the availability of deductions, and California tax treatment may outweigh the federal bracket difference.
2027 Section 199A Qualified Business Income Thresholds
Section 199A remains a significant planning provision for eligible owners of sole proprietorships, partnerships, S corporations, and certain other pass through businesses.
The deduction can generally equal up to 20% of qualified business income, subject to the taxable income limitation, W-2 wage and property limitations, and specified service trade or business restrictions.
Revenue Procedure 2026-35 establishes the following 2027 taxable income thresholds:
| Filing status | Threshold | Upper end of phase in range |
|---|---|---|
| Married filing jointly | $416,600 | $566,600 |
| Married filing separately | $208,325 | $283,325 |
| All other returns | $208,300 | $283,300 |
Beginning in 2026, Public Law 119-21 expanded the applicable phase in ranges to $150,000 for joint returns and $75,000 for other returns. The expanded ranges remain relevant for 2027.
For 2027, Section 199A also provides an inflation adjusted minimum deduction of $415 for qualifying applicable taxpayers with at least $1,030 of aggregate qualified business income from businesses meeting the statutory participation requirements.
The wage and property limitations can affect the deduction for higher income non SSTB owners. For specified service trades or businesses, eligibility can be reduced or eliminated as taxable income rises through the applicable phase in range.
Owners planning substantial compensation, retirement contributions, capital purchases, or business restructuring should evaluate how those decisions affect both taxable income and qualified business income.
See my Section 199A planning guide for business owners for the underlying qualification rules.
2027 Section 179 Expensing Limits Increase
For tax years beginning in 2027, the federal Section 179 maximum deduction increases to $2,640,000.
The investment phaseout begins when qualifying Section 179 property placed in service during the year exceeds $4,230,000.
The separate Section 179 limitation for certain sport utility vehicles increases to $33,100.
| Section 179 amount | 2026 | 2027 |
|---|---|---|
| Maximum federal deduction | $2,560,000 | $2,640,000 |
| Investment phaseout threshold | $4,090,000 | $4,230,000 |
| Certain SUV limitation | $32,000 | $33,100 |
Section 179 remains subject to the applicable taxable business income limitation. The increase in the dollar maximum does not establish that every taxpayer can deduct the entire amount.
Bonus depreciation under Section 168(k) operates separately. Under Public Law 119-21, qualifying property acquired after January 19, 2025 generally can qualify for permanent 100% additional first year depreciation, subject to the applicable acquisition and placed in service rules.
Because Section 179 and bonus depreciation have different limitations and election procedures, the largest immediate deduction is not always the best multiyear tax result.
For more detail, see Bonus Depreciation vs Section 179: Which Is Better for Business Owners After OBBBA.
Other 2027 Business Planning Limits
Revenue Procedure 2026-35 also increases several other amounts affecting business owners.
- Section 448(c) gross receipts test: $33 million for qualifying tax years beginning in 2027, based on the applicable three year average gross receipts calculation and aggregation rules.
- Excess business loss limitation under Section 461(l): $264,000 for taxpayers other than joint filers and $528,000 for joint returns.
- Monthly qualified transportation and parking benefit limit: $350.
- Health flexible spending arrangement salary reduction limit: $3,500, with a maximum permitted carryover of $700 for plans allowing carryovers.
These amounts can affect accounting methods, the deductibility of business losses, employee benefit planning, and the timing of taxable income.
In particular, the Section 461(l) limitation can prevent an individual business owner from using the entire current year business loss against nonbusiness income. The result depends on the applicable loss computation and other tax limitations.
These decisions are part of broader proactive federal and California tax planning for business owners and high income taxpayers.

2027 Estate and Gift Tax Exclusions
Estate and gift planning thresholds also increase for calendar year 2027.
| Federal provision | 2026 | 2027 |
|---|---|---|
| Basic estate and gift tax exclusion | $15,000,000 | $15,480,000 |
| Annual gift tax exclusion per donee | $19,000 | $20,000 |
| Annual exclusion for qualifying gifts to a noncitizen spouse | $194,000 | $201,000 |
The $15,480,000 basic exclusion is also relevant to the generation skipping transfer tax exemption under the applicable provisions.
For married couples, portability and the deceased spousal unused exclusion amount can affect the combined estate tax planning calculation when the necessary requirements and elections are satisfied.
Annual exclusion gifts generally must satisfy the present interest requirements. The $20,000 amount should not be interpreted as an unrestricted exclusion for every transfer to a trust or other recipient.
Gift and estate planning should also consider income tax basis, asset appreciation, beneficiary circumstances, and federal and state estate taxation.
2027 Child Tax Credit and Alternative Minimum Tax
For 2027, the maximum federal Child Tax Credit increases to $2,300 per qualifying child, with up to $1,800 potentially refundable under the applicable rules.
The actual available credit depends on the child's eligibility, the taxpayer's filing status, identification requirements, income phaseouts, and other statutory limitations.
The alternative minimum tax exemptions also increase:
- Unmarried individuals: $93,000 exemption, with the phaseout beginning at $515,950.
- Married filing jointly: $144,700 exemption, with the phaseout beginning at $1,031,900.
The AMT is a separate federal tax computation. The increase in the exemption amount does not eliminate AMT exposure for taxpayers with significant adjustment or preference items.
The General Federal Form 1099 Threshold Increases Again in 2027
Another adjustment relevant to businesses is the federal reporting threshold for qualifying payments under Section 6041(a).
Public Law 119-21 increased the threshold for many reportable payments to $2,000 beginning with payments made during 2026 and provided for subsequent inflation adjustments.
Revenue Procedure 2026-35 establishes a $2,100 threshold for qualifying payments made during calendar year 2027.
The amount generally affects the relevant payment reporting categories, including certain nonemployee compensation payments through the statutory cross reference in Section 6041A.
Different thresholds and rules continue to apply to certain information return categories, and backup withholding can create reporting obligations independently of the normal payment threshold.
Businesses must use the $2,000 threshold when evaluating applicable 2026 payments and should not prematurely substitute the $2,100 amount.
See my 2026 Form 1099 reporting and IRS filing changes guide for the relevant filing system and reporting procedures.
California Tax Rules Must Be Evaluated Separately
The federal tax brackets, standard deductions, and other inflation adjustments discussed above do not automatically determine a California taxpayer's state income tax liability.
California has its own tax rates, standard deductions, exemption credits, and inflation adjustment procedures.
California also does not conform to several important federal benefits, including the federal Section 199A deduction and federal bonus depreciation under Section 168(k).
For 2026, the California Franchise Tax Board announced a 3.4% California inflation indexing rate and separately published selected California standard deduction and exemption credit amounts.
Those are 2026 state figures. They should not be described as California's 2027 amounts.
The federal amounts released in Revenue Procedure 2026-35 should therefore be used for federal tax planning, while California tax projections should apply independently verified California rules for the applicable year.
What Should Taxpayers Do With the 2027 Figures?
The IRS announcement is useful for planning, but the new thresholds do not automatically make it beneficial to defer income or accelerate deductions.
For higher income individuals and business owners, the priority is to compare projected tax consequences across years.
- Review income timing: Compare expected taxable income in 2026 and 2027, including capital gains, bonuses, business income, and significant distributions.
- Recalculate Section 199A: Determine whether projected taxable income falls below, within, or above the applicable 2027 phase in range.
- Plan capital expenditures: Evaluate the Section 179 election, bonus depreciation, and the value of preserving future deductions.
- Evaluate capital gains: Consider the full federal taxable income calculation, special gain rates, and California taxation before deciding when to sell.
- Review estate and gift planning: Consider the higher federal annual gift exclusion and basic estate tax exclusion together with income tax basis consequences.
- Update compliance systems: Prepare for the 2027 information reporting threshold without applying it to 2026 payments.
A multiyear projection is generally more useful than comparing one inflation adjusted threshold in isolation.
Final Takeaway
Revenue Procedure 2026-35 establishes the federal inflation adjusted limits for tax year 2027. The most significant changes for higher income taxpayers and business owners include the income tax bracket thresholds, Section 199A phase in amounts, Section 179 deduction limits, and estate and gift tax exclusions.
The federal Form 1099 general reporting threshold also increases to $2,100 for qualifying payments made during 2027.
These adjustments are applicable to the 2027 tax year, generally reported in 2028. They should not be applied to 2026 tax returns or substituted for separate California limits.
