Executive Summary: The Post-OBBBA Tax Landscape
The 2026 tax filing season represents a pivotal shift in United States tax administration, driven primarily by the implementation of the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025. This legislation has fundamentally altered the standard deduction structure, introduced new savings vehicles for minors, and reshaped enforcement priorities.
For the first time in two years, the IRS Direct File pilot program has been suspended, requiring taxpayers to return to private sector software or the traditional IRS Free File alliance. Simultaneously, the IRS is aggressively targeting high-income non-filers (specifically those earning above $400,000) while rolling out the Simple Notice Initiative to modernize taxpayer communication.
Critical Updates for Filing Season 2026 (Tax Year 2025)
Taxpayers filing their 2025 returns in early 2026 will encounter significantly adjusted thresholds and new forms. The OBBBA included a statutory 5% boost to the standard deduction on top of standard inflation adjustments.
New Standard Deduction Amounts
| Filing Status | 2025 Tax Year Amount (Filed 2026) | Change from Prior Year |
|---|---|---|
| Single | $16,100 | Increased (Inflation + 5% OBBBA Boost) |
| Married Filing Jointly (MFJ) | $32,200 | Increased (Inflation + 5% OBBBA Boost) |
| Head of Household | $24,150 | Increased |
The “Senior Bonus” Deduction
A major provision of the OBBBA is the new Senior Tax Deduction. Taxpayers aged 65 and older may now claim an additional deduction separate from the standard age-related bump. This deduction is means-tested:
- Single Filers (65+): Up to $6,000 additional deduction (Phases out starting at $75,000 MAGI).
- Married Couples (Both 65+): Up to $12,000 additional deduction (Phases out starting at $150,000 MAGI).
New Entity: Trump Savings Accounts (Form 4547)
Perhaps the most distinct addition to the 2026 tax ecosystem is the Trump Savings Account, a custodial-style traditional IRA designed for minors. While the accounts themselves will not be fully operational until July 5, 2026, parents must take action during this filing season.
Election Procedure
To establish eligibility and claim the government’s “seed money,” parents must file Form 4547 with their 2025 tax return. Key features include:
- Seed Contribution: A one-time $1,000 federal contribution for U.S. citizens born between Jan 1, 2025, and Dec 31, 2028.
- Contribution Limits: Up to $5,000 annually from family members.
- Employer Match: Employers can contribute up to $2,500 of that total, often via pre-tax payroll deductions.
Warning: Failure to file Form 4547 with the 2025 return may delay the account opening process and the receipt of the pilot program seed funds.
Enforcement Priorities & The “Dirty Dozen”
Despite budget reallocations, the IRS maintains a rigorous enforcement posture focused on closing the tax gap. The Strategic Operating Plan has been updated to reflect new legislative realities.
Targeting High-Income Non-Filers
The agency is utilizing advanced data analytics to identify individuals with income exceeding $400,000 who have failed to file returns for tax years 2017–2021. More than 125,000 compliance letters (CP-59 Notices) have been deployed, signaling a shift from education to active enforcement.
2026 Dirty Dozen Tax Scams
Taxpayers must remain vigilant against the following prevailing schemes:
- Ghost Preparers: Unethical tax return preparers who refuse to sign returns or include their PTIN (Preparer Tax Identification Number), often promising inflated refunds.
- ERC Mills: Aggressive promoters continuing to push ineligible claims for the Employee Retention Credit, despite the moratorium and increased audits.
- Social Media “W-2 Hacks”: Viral misinformation on platforms like TikTok urging users to manually alter W-2 withholding information in tax software to trigger fraudulent refunds. This is classified as filing a frivolous return, carrying a $5,000 penalty.
- Fake “Self-Employment Tax Credits”: Scammers marketing non-existent refundable credits to gig workers.
Modernization: The Simple Notice Initiative
The IRS continues its digital transformation under the Simple Notice Initiative. For the 2026 filing season, hundreds of common notices (such as the 5071C Identity Verification letter) have been redesigned.
Key Improvements:
- QR Codes: direct links to IRS online accounts for immediate response.
- Plain Language: Reduction of legal jargon in favor of clear, action-oriented headlines.
- Length Reduction: Many notices have been cut from 7+ pages down to 2 pages.
Energy Credit Phase-Outs
The OBBBA has accelerated the sunsetting of several Inflation Reduction Act (IRA) energy credits. Taxpayers planning green energy investments must note the following deadlines:
- Solar & Wind Projects: Credits are terminated for projects beginning construction after July 4, 2026.
- EV Credits: Modified income and MSRP caps apply, with stricter “Foreign Entity of Concern” (FEOC) rules in full effect for vehicles placed in service in 2026.
