October 2026 is an important month for U.S. taxpayers, particularly individuals who requested an extension to file their 2025 federal income tax return. The IRS has also introduced and updated several tax provisions that affect tax year 2026.

October 15, 2026 IRS Tax Deadline
Taxpayers who timely requested an extension for their 2025 federal individual income tax return generally have until October 15, 2026 to file. The IRS tax calendar also lists October 15 as the filing deadline for several other taxpayers and entities that received applicable extensions.
An extension gives additional time to file a tax return, but it does not extend the deadline for paying federal income taxes. Taxes generally remained due by April 15, 2026.
Important: If you still have an unpaid federal tax balance, interest and applicable penalties may continue to accrue. Taxpayers should pay as much as they can as soon as possible.
Who Should Check the October 15 Deadline?
The October deadline is especially relevant to individuals who submitted Form 4868 or otherwise received a valid extension for their 2025 federal return.
- Individuals who requested a six-month federal tax filing extension.
- Taxpayers who still need to complete their 2025 Form 1040.
- Taxpayers who need additional time to organize tax documents.
- Eligible nonresident taxpayers with an applicable extension.
- Other taxpayers or entities whose applicable IRS extension ends October 15.
2026 Standard Deduction Amounts
The IRS has announced inflation-adjusted standard deduction amounts for tax year 2026. These amounts generally apply to tax returns filed in 2027.
| Filing Status | 2026 Standard Deduction |
|---|---|
| Single | $16,100 |
| Married Filing Jointly | $32,200 |
| Head of Household | $24,150 |
| Married Filing Separately | $16,100 |
These are tax year 2026 amounts and generally apply to returns filed in 2027.
2026 Federal Income Tax Rates
The federal individual income tax rates for 2026 remain 10%, 12%, 22%, 24%, 32%, 35% and 37%. The income thresholds have been adjusted for inflation.
| Rate | Single Taxpayer - Taxable Income Above |
|---|---|
| 10% | $0 to $12,400 |
| 12% | $12,400 |
| 22% | $50,400 |
| 24% | $105,700 |
| 32% | $201,775 |
| 35% | $256,225 |
| 37% | $640,600+ |
Federal income tax rates are marginal. Taxable income can be divided among different tax brackets rather than being taxed entirely at the highest rate reached.
Major Tax Changes Affecting 2026
Deduction for Qualified Tips
Eligible workers may claim a federal income tax deduction for qualified tips, subject to occupation, income and other requirements. The deduction can be available whether a taxpayer itemizes or takes the standard deduction.
Deduction for Qualified Overtime
Eligible taxpayers may deduct qualified overtime compensation. The maximum deduction is $12,500, or $25,000 for married couples filing jointly, subject to applicable limitations.
Car Loan Interest Deduction
Eligible taxpayers may deduct up to $10,000 of qualified passenger vehicle loan interest. The vehicle and loan must satisfy the applicable IRS requirements.
Enhanced Senior Deduction
Eligible taxpayers age 65 or older may claim an additional deduction of up to $6,000 per qualifying individual, subject to income phaseouts and other requirements.
New Senior Tax Deduction
For tax years 2025 through 2028, eligible individuals age 65 or older may claim an additional $6,000 deduction. A married couple may potentially claim up to $12,000 when both spouses qualify.
The deduction phases out when modified adjusted gross income exceeds $75,000 for single taxpayers and $150,000 for married couples filing jointly.
Qualified Overtime Tax Deduction
Eligible workers can claim a deduction for qualified overtime compensation. For tax years covered by the new provision, the maximum annual deduction is $12,500 for most taxpayers and $25,000 for married couples filing jointly.
The deduction phases out for taxpayers with modified adjusted gross income above $150,000, or $300,000 for married couples filing jointly.
Qualified Tip Deduction
Eligible tipped workers may deduct qualified tips received during the applicable tax year. The maximum deduction can be up to $25,000 per return, subject to the applicable income limitations, occupational requirements and reporting rules.
Car Loan Interest Deduction
Certain taxpayers can claim a deduction for interest paid on qualifying vehicle loans. The maximum deduction is $10,000 per year for eligible taxpayers.
The vehicle must satisfy IRS requirements, and the deduction generally applies to qualified personal-use vehicle loans. Lease payments do not qualify for this deduction.
IRS Tax Withholding Estimator Updated
The IRS has updated its Tax Withholding Estimator to account for recent tax-law changes, including deductions related to qualified tips, overtime, car loan interest and seniors.
Employees and retirees can use the estimator to review their federal income tax withholding and determine whether they may need to adjust withholding for future tax obligations.
What Happens If You Miss October 15?
Taxpayers who received an extension should file as soon as possible if they cannot meet the October 15 deadline. A filing extension does not eliminate the requirement to file a federal return.
Late-filing penalties and interest may apply when applicable. Taxpayers who owe money should also pay as much as possible because the extension does not extend the payment deadline.
