The IRS made several meaningful updates that affect how individuals prepare the 2025 Form 1040 (filed in 2026). Below is a clear, item-by-item breakdown of the most important changes, including new deductions, updated credits, and rules that impact itemized deductions and reporting.
1 – Higher 2025 Standard Deduction
For tax year 2025, the standard deduction increases to:
• $15,750 for Single and Married Filing Separately (MFS)
• $31,500 for Married Filing Jointly (MFJ) and Qualifying Surviving Spouse (QSS)
• $23,625 for Head of Household (HOH)
2 – SALT Deduction Cap Increase (Schedule A)
If you itemize deductions, the limit on deducting state and local taxes (SALT) changes:
• New SALT cap: $40,000 (or $20,000 if MFS)
• A MAGI-based phase-down begins above $500,000 (or $250,000 if MFS), but the cap generally won’t drop below $10,000 (or $5,000 if MFS)
3 – New Schedule 1-A for Additional Deductions
A new schedule is introduced to claim certain new 2025 deductions. These amounts then flow to the appropriate line on Form 1040, reducing taxable income when eligible.
4 – “No Tax on Tips” Deduction (Schedule 1-A)
Taxpayers may be able to deduct qualified tips, up to:
• $25,000 of eligible tip income
This deduction generally phases out when MAGI exceeds $150,000 (or $300,000 for MFJ). Specific filing status and SSN requirements apply.
5 – “No Tax on Overtime” Deduction (Schedule 1-A)
Eligible taxpayers may be able to deduct qualified overtime pay, up to:
• $12,500 (or $25,000 for MFJ)
This deduction generally phases out above $150,000 MAGI (or $300,000 for MFJ). Specific SSN and filing requirements apply.
6 – Car Loan Interest Deduction (Schedule 1-A)
A new deduction may allow taxpayers to deduct qualified passenger vehicle loan interest, up to:
• $10,000 of eligible interest
This deduction generally phases out above $100,000 MAGI (or $200,000 for MFJ). Vehicle identification and other eligibility rules apply.
7 – Enhanced Senior Deduction (Schedule 1-A)
Older taxpayers may qualify for an additional deduction of:
• $6,000 per eligible person (up to $12,000 if both spouses qualify on a joint return)
This benefit generally phases out above $75,000 MAGI (or $150,000 for MFJ), and additional eligibility requirements apply.
8 – Child Tax Credit (CTC) and Additional CTC Updates
For 2025, the Child Tax Credit is updated:
• Maximum CTC increases to $2,200 per qualifying child
• Up to $1,700 may be refundable as the Additional Child Tax Credit (ACTC)
There are also tighter SSN timing requirements tied to the return due date (including extensions).
9 – Adoption Credit Becomes Partially Refundable
For eligible adoption expenses, the adoption credit rules change so that:
• Up to $5,000 may be refundable (depending on eligibility and how the credit is calculated)
10 – Clean Vehicle Credits Limited After September 30, 2025
Clean vehicle credits (including certain EV credits) are curtailed for many taxpayers:
• Credits are generally not available for vehicles acquired after September 30, 2025
Exact rules depend on vehicle type and qualifying requirements.
11 – Home Energy Credits End After 2025 (Form 5695)
If you claim energy credits for home improvements or residential clean energy, note the phaseout timing:
• The Energy Efficient Home Improvement Credit (25C) generally ends for property placed in service after December 31, 2025
• The Residential Clean Energy Credit (25D) generally ends for expenditures after December 31, 2025
12 – Digital Asset Reporting Expands (Form 1099-DA)
Tax year 2025 includes expanded information reporting for digital assets:
• Brokers may issue Form 1099-DA for certain digital asset sales
• For 2025, broker basis reporting may be limited, so taxpayers may need to rely on their own records for cost basis and gain/loss calculations
