South Carolina Overtime Tax Deduction & Paycheck Guide (2026)

The no tax on overtime calculator for South Carolina helps hourly employees and employers evaluate the exact paycheck and tax savings generated under federal and state overtime legislation. This guide breaks down statutory enactment dates, federal deduction mechanics, and take-home pay calculations for workers across South Carolina.

When Does No Tax on Overtime Start in South Carolina?

Under the federal statutory timeline established by the One Big Beautiful Bill Act (OBBBA), the Qualified Overtime Compensation Deduction follows a two-stage rollout. For 2025 taxes, the deduction applies retroactively on Form 1040 Schedule 1 when filing annual tax returns. For 2026 through 2028, employers across South Carolina can apply updated IRS Publication 15-T withholding formulas directly to regular paychecks. In South Carolina, where major economic drivers include Automotive Assembly (BMW), Aerospace (Boeing), Port Logistics, Tire & Rubber Manufacturing, hourly wage earners with a Bureau of Labor Statistics benchmark average of $27.90/hr can utilize this tool to determine whether claiming the deduction via annual tax refund or updating Form W-4 Step 4(b) yields the highest immediate financial relief.

How Does No Tax on Overtime Work in South Carolina?

To understand how does no tax on overtime work in South Carolina, workers must differentiate between federal and state tax rules. Federally, the deduction applies exclusively to the statutory 0.5× overtime premium portion of time-and-a-half wages (equal to one-third of total gross overtime earnings), up to annual caps of $12,500 for Single filers and $25,000 for Married couples filing jointly. Mandatory FICA payroll taxes (6.2% Social Security and 1.45% Medicare) remain fully intact to protect future retirement credits.

At the state level, South Carolina enforces a progressive individual income tax structure with an effective modeling rate of 5%. South Carolina updates its conformity to the Internal Revenue Code annually. Federal taxable income forms the basis on South Carolina Form SC1040. Workers filing in South Carolina should verify whether their state tax return automatically adopts federal Adjusted Gross Income (AGI) or requires a separate state-level deduction adjustment.
