Meta Title: 2026 Guide: Step-by-Step Instructions for IRS Form 1040
Meta Description: Filing your 2025 taxes in 2026? Use our detailed step-by-step guide to navigate Form 1040, including new Schedule 1-A deductions, updated standard deduction amounts, and e-filing tips.
Filing Form 1040 is the cornerstone of the U.S. tax system. For the 2026 filing season (reporting 2025 income), the process has been updated to include significant changes from the One, Big, Beautiful Bill Act (OBBBA). These changes introduce new “below-the-line” deductions that can significantly reduce your taxable income.
Follow this workflow to complete your 1040 with precision.
Step 1: Complete Personal Information
The top of Form 1040 requires your basic identity data.
- Filing Status: Choose from Single, Married Filing Jointly (MFJ), Married Filing Separately (MFS), Head of Household (HOH), or Qualifying Surviving Spouse (QSS).
- Digital Assets: You must answer the mandatory question: “At any time during 2025, did you receive, sell, exchange, or otherwise dispose of a digital asset?”
- Standard Deduction Checkboxes: Indicate if someone can claim you as a dependent or if you (or your spouse) were born before January 2, 1961 (Senior status).
Step 2: Calculate Gross Income (Lines 1z – 9)
Report all income earned in 2025, whether in the U.S. or abroad.
- Line 1z: Total wages, salaries, and tips (from W-2s).
- Lines 2-3: Tax-exempt and taxable interest and dividends.
- Line 7a: Capital gains or losses (Attach Schedule D if necessary).
- Line 8: Additional income from Schedule 1 (includes business income, rental income, or gambling winnings).
- Total Income (Line 9): The sum of all your income sources.
Step 3: Determine Adjusted Gross Income (AGI)
- Line 10: Subtract “Adjustments to Income” from Schedule 1, Part II. This includes student loan interest, educator expenses, and HSA contributions.
- Line 11a: This is your Adjusted Gross Income (AGI), the most important number for determining your eligibility for various credits.
Step 4: Claim New 2025 Deductions (Schedule 1-A)
New for the 2026 filing season, the OBBBA has introduced Schedule 1-A for “Additional Deductions.” These apply even if you take the standard deduction:
- No Tax on Tips: Deduct qualified tips up to $25,000.
- No Tax on Overtime: Deduct qualified overtime pay up to $12,500 ($25,000 for MFJ).
- Car Loan Interest: Deduct up to $10,000 in interest paid on loans for U.S.-assembled vehicles.
- Enhanced Senior Deduction: An additional $6,000 deduction for those aged 65+.
Step 5: Apply the Standard or Itemized Deduction
Compare your total itemized deductions (Schedule A) against the 2025 Standard Deduction:
- Single / MFS: $15,750
- Married Filing Jointly: $31,500
- Head of Household: $23,625
SALT Update: The cap for State and Local Tax (SALT) deductions has increased to $40,000 for 2025, providing a significant boost for filers in high-tax states.
Step 6: Final Tax and Credits (Lines 16 – 38)
- Line 16: Calculate your tax using the 2025 tax tables or the Qualified Dividends and Capital Gains Worksheet.
- Credits: Claim non-refundable credits (like the Foreign Tax Credit on Schedule 3) and refundable credits (like the Child Tax Credit, now $2,200 per child).
- Payments: Total your federal withholding and any estimated tax payments.
- The Result: If Line 33 (Total Payments) is more than Line 24 (Total Tax), you are due a Refund (Line 35a). If not, you have an Amount You Owe (Line 37).
