The One Big Beautiful Bill: What Federal Employees Need to Know for 2026 Taxes

The One Big Beautiful Bill Act introduced three new tax deductions effective 2026: overtime pay, tipped wages, and auto loan interest. Here's exactly how they work, who qualifies, and what the 2026 standard deduction and tax brackets look like.

The One Big Beautiful Bill Act (OBBBA) was signed into law in July 2025, introducing several tax provisions that take effect in 2026. For federal employees, the most relevant changes are three new "above-the-line" deductions — meaning they reduce your income even if you take the standard deduction. Here's what changed and how to calculate your benefit.

What Changed: The Three New Deductions

1. Overtime Pay Deduction

If you earned overtime pay in 2026, you can deduct the premium portion — the extra compensation above your regular rate — from your taxable income.

Limits:

  • Up to $12,500 for single filers, heads of household, and married filing separately
  • Up to $25,000 for married filing jointly

MAGI phase-out: This deduction phases out for higher earners. For single filers, it begins to reduce once your MAGI (Modified Adjusted Gross Income) exceeds $150,000 and phases out completely above that threshold. For married filing jointly, the threshold is $300,000.

For a GS-13 employee in a major metropolitan area earning $15,000 in overtime premium pay and filing single with income under $150,000:

Overtime deduction: $12,500 (capped at the single limit) At a 22% marginal rate: $2,750 in tax savings

2. Tips Deduction

If you received tips as part of your compensation, you can deduct those from your taxable income under the same limits and MAGI thresholds as the overtime deduction.

Limits:

  • Up to $12,500 single / $25,000 MFJ

This provision is primarily targeted at tipped workers in hospitality and food service, but applies to any taxpayer who receives tips as compensation. Federal employees who work secondary jobs or have tip-eligible income benefit as well.

3. Auto Loan Interest Deduction

Interest paid on a loan for a new personal vehicle purchased in 2026 is deductible, up to a point.

Limit: The interest deduction is available for income below $100,000 MAGI (single) or $200,000 MAGI (MFJ). There is no stated dollar cap in the legislation, though the deduction is limited to the actual interest paid.

For a federal employee who purchased a new vehicle in 2026 and paid $3,200 in auto loan interest with income under the threshold:

Auto loan interest deduction: $3,200 At 22% marginal rate: $704 in tax savings

These three deductions stack — you can claim all three if you qualify for each.

The 2026 Standard Deduction

Most federal employees take the standard deduction rather than itemizing. The 2026 figures:

Filing StatusStandard Deduction
Single$16,100
Married Filing Jointly$32,200
Head of Household$24,150
Married Filing Separately$16,100

The OBBBA deductions (overtime, tips, auto loan interest) are above-the-line deductions taken before you reach the standard deduction calculation. This is important: you claim the OBBBA deductions regardless of whether you itemize or take the standard deduction.

The Senior Deduction

The OBBBA also introduced a $6,000 additional deduction for taxpayers age 65 and older. This is available regardless of whether you itemize or take the standard deduction, similar to the other OBBBA provisions.

MAGI threshold: $75,000 for single filers; $150,000 for married filing jointly.

For federal retirees in the 62+ age bracket, this provides meaningful additional tax relief.

2026 Federal Tax Brackets

For reference, the 2026 income tax brackets:

Single filers:

Taxable IncomeRate
$0 – $12,40010%
$12,400 – $50,40012%
$50,400 – $105,70022%
$105,700 – $201,77524%
$201,775 – $256,22532%
$256,225 – $640,60035%
Over $640,60037%

Married filing jointly:

Taxable IncomeRate
$0 – $24,80010%
$24,800 – $100,80012%
$100,800 – $211,40022%
$211,400 – $403,55024%
$403,550 – $512,45032%
$512,450 – $768,70035%
Over $768,70037%

How This Interacts with TSP and FSA

The OBBBA deductions come after your TSP Traditional contributions and pre-tax FSA/HSA elections reduce your gross income. In planning terms:

  1. Start with gross income
  2. Subtract Traditional TSP contributions (pre-tax)
  3. Subtract FSA and HSA elections (pre-tax)
  4. This gives you your MAGI for phase-out purposes
  5. Then subtract eligible OBBBA deductions (overtime, tips, auto loan, senior)
  6. Then subtract the standard deduction (or itemized total)
  7. The result is your taxable income

Maximizing your Traditional TSP contributions first lowers your MAGI, which can keep you under the OBBBA phase-out thresholds — a meaningful sequencing consideration for higher-earning employees.

A Note on OBBBA Duration

The OBBBA provisions are currently scheduled through tax year 2028, subject to Congressional extension. Retirement planning projections should account for the possibility that these deductions may not be available after 2028. High-3 Retirement Planner applies OBBBA deductions for the 2026 tax year calculation and notes their scheduled expiration.
