$18/Hour with 5 Overtime Hours/Week: 2026 No Tax on Overtime (W-2 Code TT) Calculator

How much is the 2026 overtime tax deduction for $18/hr Hourly Worker (5 OT hrs/wk)?

At $18/hour working 5 FLSA overtime hours per week for 50 weeks, your gross 1.5x overtime pay is $6,750, and your qualified 0.5x half-time overtime premium (reported in 2026 Form W-2 Box 12, Code TT) is $2,250, saving roughly $495 in federal tax.

Under Public Law 119-21 (IRS Schedule 1-A, Part III), the 2026 "No Tax on Overtime" deduction applies strictly to the FLSA-required 0.5x half-time premium portion of time-and-a-half pay for hours worked over 40 in a workweek. For 2026, your employer must report this exact 0.5x amount in Form W-2, Box 12, Code TT.

Frequently Asked Questions

Why is my W-2 Box 12 Code TT only one-third of my total 1.5x overtime pay at $18/hour?

Because the federal FLSA overtime deduction only exempts the 0.5x half-time premium ($9.00/hr) above your regular $18/hr base wage, which equals exactly one-third of your $27.00/hr time-and-a-half pay.

What is the maximum 2026 Schedule 1-A overtime deduction cap?

The maximum deduction is $12,500 for Single and Head of Household filers, and $25,000 for Married Filing Jointly, phasing out above $150,000 ($300,000 MFJ) MAGI.
