When Does No Tax on Overtime Start Across the States?

A frequent question among workers is: when does no tax on overtime start in each individual state? Under the federal One Big Beautiful Bill Act (OBBBA), the Qualified Overtime Compensation Deduction takes effect for tax years 2025 through 2028. For 2025 taxes, the relief operates retroactively when filing federal Form 1040 Schedule 1. Starting in 2026, employers can apply revised IRS withholding formulas across all states. However, state-level implementation depends on each state's internal tax code and legislative calendar.

How Does No Tax on Overtime Work Across Different State Tax Systems?

To understand how does no tax on overtime work at the state level, taxpayers must consider three distinct categories of state income taxation:

• 0% State Income Tax States (9 States): In Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Tennessee, and Alaska, there is zero state personal income tax on wage income. Workers in these states retain 100% of their federal overtime tax savings without state tax clawbacks or adjustments.
• Flat Tax States: States like Pennsylvania (3.07%), Michigan (4.25%), Indiana (3.05%), Arizona (2.5%), North Carolina (4.5%), and Illinois (4.95%) levy a single flat percentage on taxable income. Flat tax states that conform to federal Adjusted Gross Income (AGI) pass federal overtime deductions directly to state returns.
• Progressive Bracket States: States such as California, New York, Ohio, Virginia, and Georgia maintain graduated marginal brackets. In these jurisdictions, overtime surges can be taxed at top marginal state rates unless state legislatures pass conforming statutes.

State Tax Conformity & Labor Standards

State tax treatment is governed by Internal Revenue Code (IRC) conformity. Rolling conformity states automatically incorporate federal above-the-line deductions, whereas fixed-date or selective conformity states (such as California or Arkansas) require explicit state legislation. Additionally, daily overtime mandates—such as California's 8-hour daily overtime rule or Alaska's daily threshold—trigger overtime premiums earlier than federal 40-hour weekly rules.
