Looking for 2026 Tax Changes? Here Are 10 Things Every Pro Should Know Before April

The 2026 tax filing season is governed by significant legislative shifts. The primary driver of these changes is the One Big Beautiful Bill Act (OBBBA), which was signed into law in July 2025. This legislation made several provisions of the previous Tax Cuts and Jobs Act permanent while introducing new deductions designed to address inflation and specific labor sectors.

Tax professionals must update their internal processes and software configurations to reflect these adjustments before the April deadline. Failure to apply these changes accurately can lead to rejected returns or missed savings for clients.

1. Increased Standard Deductions

For the 2026 tax year, standard deductions have been adjusted upward to account for inflation. These figures determine the baseline of non-taxable income for the majority of taxpayers.

• Single filers: $16,100
• Married filing jointly: $32,200
• Heads of household: $24,150

Professional tax preparation requires verifying if a client's itemized deductions exceed these new thresholds. Given the increase, more taxpayers will likely benefit from the standard deduction than in previous years.

2. Updated Federal Income Tax Brackets

Federal income tax brackets have been recalibrated for 2026. The thresholds for each percentage tier have shifted, meaning taxpayers can earn more income before moving into a higher tax bracket.

• The 10% bracket now applies to income up to $12,400 for single filers and $24,800 for married couples filing jointly.
• Middle and upper brackets have seen proportional increases.

Tax professionals should use Essential Tax Software to ensure these tiered calculations are applied correctly across diverse client portfolios.

3. New Qualified Tip Deduction

A major inclusion in the OBBBA is the deduction for service industry workers receiving tips. This provision allows eligible employees to deduct up to $25,000 in qualified tips from their taxable income annually.

Eligibility and Constraints:

• The deduction is available to employees in service-related sectors.
• Phaseout of this benefit begins at an adjusted gross income (AGI) of $150,000 for single filers.
• Documentation of tip income through employer records or personal logs is mandatory for compliance.

4. Overtime Compensation Deduction

To incentivize labor participation, the 2026 code introduces a deduction for overtime pay. Workers who receive qualified overtime compensation can now reduce their taxable income significantly.

• Individual limit: Up to $12,500.
• Joint limit: Up to $25,000.
• Phaseout thresholds: Benefits begin to reduce at $150,000 for single filers and $300,000 for married couples.

Tax preparers must distinguish between base salary and "qualified overtime" as defined by the new statutes to apply this deduction accurately.

5. Car Loan Interest Deduction

Interest paid on vehicle loans is now deductible under specific conditions for the 2026 tax year. This marks a return to policies that favor individual debt relief for necessary transportation.

• Deduction limit: Up to $10,000 in interest.
• Income limits: Phaseout begins at $100,000 for single filers and $200,000 for joint filers.

This deduction applies to personal vehicles used for commuting or general use, provided the income requirements are met.

6. Expanded Charitable Giving for Standard Deduction Filers

The OBBBA has expanded the "above-the-line" deduction for charitable contributions. Taxpayers who do not itemize can still reduce their taxable income by reporting donations.

• Individual limit: $1,000.
• Joint limit: $2,000.

This is a permanent change intended to encourage philanthropy among a broader range of income earners. Tax pros should check updates regularly for any localized state-level deviations from this federal rule.

7. Major Increase to the SALT Deduction Cap

One of the most impactful changes for 2026 is the revision of the State and Local Tax (SALT) deduction. The previous $10,000 cap, which had been in place since 2017, has been substantially increased.

• New SALT limit: $40,400.
• Phaseout: Begins at $505,000 Modified Adjusted Gross Income (MAGI) for single filers.

This change particularly benefits taxpayers in high-tax states. It necessitates a more detailed review of property taxes and state income taxes paid during the 2025 calendar year.

8. Permanent Status of the QBI Deduction

The Section 199A Qualified Business Income (QBI) deduction, which allows small business owners and pass-through entities to deduct up to 20% of their business income, has been made permanent.

Updated Thresholds for 2026:

• Phase-in thresholds have increased to $75,000 for individuals.
• Phase-in thresholds for joint returns have increased to $150,000.

For firms managing business clients, utilizing Unlimited Tax Software is recommended to handle the complex QBI calculations and phase-out limitations correctly.

9. Gift and Estate Tax Exemptions

The lifetime gift and estate tax credit exemption has seen a significant increase. This is critical for high-net-worth clients planning their estates or making large transfers of wealth.

• 2026 Exemption Amount: $15 million.
• This is an increase from the $13.99 million exemption in 2025.

Tax professionals should review existing estate plans to determine if the increased exemption allows for additional tax-free wealth transfers.

10. Adjustments to EITC and FEIE

The Earned Income Tax Credit (EITC) and the Foreign Earned Income Exclusion (FEIE) have both been adjusted for the 2026 season.

• Maximum EITC: Now $8,231 for eligible taxpayers with three or more qualifying children.
• FEIE Limit: Increased to $132,900.

These adjustments are mandatory for low-to-moderate-income earners and expatriate clients, respectively.

State and Local Law Variations

While the OBBBA has standardized many federal provisions, state-level conformity varies. Some states automatically adopt federal changes (rolling conformity), while others require legislative action (static conformity).

Tax professionals must verify:

1. Whether the state recognizes the new $40,400 SALT cap.
2. If the state-level standard deduction has matched the federal increase.
3. Specific state treatments of the new overtime and tip deductions.
