2026 IRS Schedule 1-a Deductions Instructions

Starting with the 2025 tax year, the IRS introduced Schedule 1-A, a new form created under the One Big Beautiful Bill (also known as the Working Families Tax Cut).

This temporary form allows eligible taxpayers to claim additional deductions that directly reduce their taxable income on Form 1040.

Schedule 1-A is available for tax years 2025 through 2028 and is first filed in 2026 when you file your 2025 return.

What Is Schedule 1-A?

Schedule 1-A is used to claim new “below-the-line” deductions, meaning:

• They are claimed after Adjusted Gross Income (AGI) is calculated
• They do not change your AGI
• They do reduce taxable income, lowering the tax you owe

The total deductions calculated on Schedule 1-A flow to Form 1040, Line 13B.

Key Deductions Available on Schedule 1-A

Schedule 1-A includes four major new deductions designed to benefit working taxpayers and seniors.

1. No Tax on Tips (Qualified Tip Deduction)

Eligible workers can deduct certain qualified tips from taxable income.

Key points:

• Applies only to qualified tips, not all tip income
• Income limits and phase-out rules apply
• Tips must be properly reported and documented

📌 Example:
A restaurant worker who earns $4,000 in qualifying tips may be able to deduct part or all of that amount, depending on income level.

2. No Tax on Overtime (Premium Pay Only)

This deduction applies only to the extra (premium) portion of overtime pay.

Important details:

• Regular hourly pay is not deductible
• Only the overtime premium (for example, the “half” in time-and-a-half) qualifies
• Documentation from pay stubs is required

📌 Example:
If you earn $30/hour and $45/hour for overtime, only the extra $15 per hour may qualify for the deduction.

3. Car Loan Interest Deduction

Schedule 1-A allows a deduction for interest paid on qualifying car loans.

Key rules:

• The loan must meet IRS qualifications
• Only interest, not principal payments, is deductible
• Lenders typically provide annual interest statements

📌 Example:
If you paid $1,100 in interest on an eligible auto loan during the year, that amount may reduce your taxable income.

4. Enhanced Deduction for Seniors (Age 65+)

Taxpayers aged 65 or older may qualify for an enhanced senior deduction in addition to existing benefits.

Highlights:

• Available only to taxpayers meeting the age requirement
• Income limits may apply
• Designed to offset fixed retirement costs

This deduction is separate from and in addition to the standard or itemized deduction.

Important Notes to Know

• Temporary Form: Only available for tax years 2025–2028
• First Filing Year: Filed in 2026 for the 2025 tax return
• Below-the-Line Deductions: These do not affect AGI
• Documentation Required:
  • Pay stubs for tips and overtime
  • Loan statements for car interest
  • Proof of age for senior deduction

Keeping accurate records is essential in case of IRS questions.

Why Electronic Filing Is Strongly Recommended

Because Schedule 1-A introduces new calculations and eligibility rules, electronic filing is the safest and most efficient option.

Benefits of e-filing include:

• Automatic calculation of overtime and tip deductions
• Built-in income phase-out checks
• Correct placement on Form 1040, Line 13B
• Reduced risk of math and reporting errors
• Faster processing and refunds
• Easier record retention and audit support

Tax software will guide you through Schedule 1-A step by step, ensuring you don’t miss deductions or misreport amounts.

Bottom Line

Schedule 1-A is a major new tax benefit for workers and seniors from 2025 through 2028, offering deductions for:

• Qualified tips
• Overtime premium pay
• Car loan interest
• Enhanced senior benefits

When used correctly, it can significantly lower your taxable income—but only if it’s calculated and reported accurately. Filing electronically makes claiming these new deductions far easier, faster, and more reliable.
