What’s New in the 2025 IRS Form 1040 Instructions?

The 2025 tax year introduces several significant updates designed to simplify filing and provide relief to various taxpayer groups. These changes are outlined in the official instructions and aim to address economic shifts and policy adjustments.

  • Trump Accounts Pilot Program: Parents or guardians of U.S. citizen children born between 2025 and 2029 can elect a $1,000 contribution to a new Trump account using Form 4547, filed alongside your 2025 return. This initiative supports long-term savings for eligible dependents.
  • Increased Standard Deductions: For single filers or married filing separately (under 65), the deduction rises to $15,750. Married filing jointly or qualifying surviving spouses get $31,500, while heads of household receive $23,625. Add $2,000 for those 65 or older (per person on joint returns).
  • New Deductions on Schedule 1-A: Taxpayers can now exclude up to $25,000 in qualified cash tips, $12,500 in overtime pay (or double for joint filers), $10,000 in qualified passenger vehicle loan interest, and an enhanced senior deduction of up to $6,000 (or $12,000 joint) for those born before January 2, 1961. These come with AGI phase-outs and require a valid SSN.
  • Child Tax Credit Enhancements: The CTC increases to $2,200 per qualifying child, with up to $1,700 refundable as the Additional Child Tax Credit (ACTC). A valid SSN issued by the return due date is required, though joint filers can use an ITIN for one spouse if issued timely.
  • State and Local Tax (SALT) Deduction Limit: Raised to $40,000 ($20,000 for married filing separately), with a phase-out starting at $500,000 AGI for singles or $250,000 for married filing separately, and a $10,000 floor ($5,000 for MFS).
  • Other Key Updates: Catch-up contributions for ages 60-63 increase to $11,250. Digital asset reporting uses new Form 1099-DA from brokers. The Alternative Minimum Tax (AMT) exemption is $88,100 for singles and $137,000 for joint filers. Form 1099-K thresholds return to $20,000 and 200 transactions for business payments.

Who Must File Form 1040 for 2025?

File if your gross income meets or exceeds the standard deduction for your status, you have self-employment income ≥$400, or you qualify for refundable credits (e.g., EIC, ACTC). Special rules apply for dependents, nonresidents, and those abroad.

  • Filing Deadline: April 15, 2026 (automatic extensions available via Form 4868, but payment due by deadline).
  • E-File Recommendation: Faster refunds; use IRS Free File if AGI qualifies.

Filing Requirements for 2025 Tax Year

Determining if you need to file a 2025 Form 1040 depends on your gross income, filing status, and age. Even if below thresholds, filing may be beneficial for refunds or credits like the Earned Income Credit (EIC) or Premium Tax Credit (PTC).

Here’s a quick overview of gross income thresholds where filing is required:

Filing Status Under 65 65 or Older
Single $15,750 $17,750
Married Filing Jointly $31,500 $33,500 (one spouse) / $35,500 (both)
Married Filing Separately $15,750 $15,750
Head of Household $23,625 $25,625
Qualifying Surviving Spouse $31,500 $33,500

Additional situations mandating a filing include self-employment income over $400, owing alternative minimum tax, or receiving advance PTC. Resident aliens file like U.S. citizens, while nonresidents may use Form 1040-NR.

The due date is April 15, 2026, with automatic extensions to October 15, 2026, via Form 4868 (though payments are due April 15 to avoid penalties). E-filing is recommended for faster processing and refunds.

Understanding Dependents, Credits, and Deductions

Qualifying for dependents can significantly reduce your tax liability through credits like the CTC.

  • Qualifying Child Rules: Must be under 19 (or 24 if student), live with you over half the year, and receive over half their support from you. Valid SSN needed for CTC.
  • Qualifying Relative: Not a qualifying child, gross income under $5,200, and you provide over half support.

New for 2025: Enhanced adoption credit up to $5,000 refundable per child, with parity for tribal adoptions.

Itemized deductions on Schedule A include medical expenses, taxes (up to SALT limit), interest, and gifts to charity. Compare to standard deduction to choose the higher amount.

Reporting Income and Handling Payments

Accurately report all income sources to avoid audits. Use Forms W-2, 1099, and new 1099-DA for digital assets. If owing taxes, pay by April 15, 2026, to avoid penalties—options include IRS Direct Pay or credit card.

For refunds, expect processing within 21 days for e-filed returns. Track status at IRS.gov/Refunds.
