Two answers for one overtime shift

An overtime paycheck creates an immediate cash-flow question and a separate annual tax-return question. The immediate result starts with all overtime pay, then estimates federal and state withholding plus employee Social Security and Medicare tax. The annual result isolates only the overtime premium required under Section 7 of the Fair Labor Standards Act and tests the temporary Section 225 deduction.

Keeping the answers separate prevents a common mistake. “No tax on overtime” is not a payroll exclusion. The gross overtime amount remains wages. The deduction is claimed on the federal return and can be reflected prospectively in withholding through a properly completed Form W-4, but it does not erase FICA tax or automatically make the current check tax free.

How the overtime paycheck increase is built

The calculator multiplies the entered FLSA regular rate by overtime hours and the paid multiplier. A $30 regular rate, ten overtime hours and a 1.5 multiplier produce $450 of overtime compensation. The regular-pay tile is shown for context but does not become part of the incremental answer.

Federal and state withholding percentages are editable planning rates. Actual federal withholding depends on the employer’s payroll method, Form W-4, pay frequency, other wages and whether the payment is combined with regular wages. Withholding is a prepayment, not the final income tax on the overtime.

Only the FLSA premium can enter the deduction

Qualified overtime compensation is the portion required under FLSA Section 7 that exceeds the worker’s regular rate. For ordinary time-and-a-half, that is generally the “half” portion, not the whole 1.5-times payment. Ten hours at a $30 regular rate generate $150 of potentially qualified premium: $30 x 0.5 x 10.

The calculator limits the premium to the smaller of the actual amount above straight time and one-half of the entered regular rate per overtime hour. That prevents a voluntary double-time payment from being treated as entirely qualified. Special FLSA systems can require different computations, so firefighters, law-enforcement personnel, hospital workers, piece-rate workers and employees receiving bonuses may need the official instructions.

The FLSA regular rate may exceed base pay

The regular rate is an hourly-rate calculation under federal labor law. It can include nondiscretionary bonuses, commissions, shift differentials and other remuneration, subject to exclusions. Dividing a visible salary or base wage by hours may not reproduce the employer’s legal regular rate.

When a bonus is allocated back to prior workweeks, additional overtime premium can become due. That incremental premium may have its own reporting. Ask payroll for the regular-rate calculation when the pay stub does not make it clear. Entering the contractual base rate can understate both pay and the potentially qualified premium.

Who is covered and nonexempt under Section 7

The deduction requires compensation mandated by FLSA Section 7. A worker must generally be covered and nonexempt, and the hours must meet the applicable federal overtime rule. Job title alone does not determine exemption. Salary basis, salary level and job duties can all matter for executive, administrative and professional exemptions.

Some employees have industry-specific rules or partial exemptions. State law or a union agreement may provide overtime even when federal Section 7 does not require it. That pay can be legally owed and fully taxable while remaining outside the federal deduction. Select “No or not confirmed” until the federal basis is established.

2026 annual cap, filing status and SSN gate

The maximum deduction is $12,500 on a nonjoint return and $25,000 on a married filing jointly return. The cap is per return, not per employer. Joint filers combine both spouses’ qualified amounts under one $25,000 ceiling.

A married taxpayer must file jointly to claim the deduction. The calculator therefore returns zero for married filing separately. The recipient also needs a valid Social Security number meeting the employment-authorization rule. An ITIN does not satisfy that gate.

The deduction is available whether the taxpayer itemizes or takes the standard deduction. It is reported through Schedule 1-A rather than Schedule A, so it should not be added to itemized deductions a second time.

MAGI phaseout for qualified overtime

After the annual cap, the deduction is reduced by $100 for each $1,000 of modified adjusted gross income above $150,000, or $300,000 on a joint return. The calculator treats that worksheet relationship as 10% of excess MAGI. It never reduces the allowed deduction below zero.

With a full $12,500 nonjoint cap, the deduction phases to zero when excess MAGI reaches $125,000. A smaller qualified amount disappears sooner. MAGI for this provision begins with AGI and adds back specified foreign-income exclusions; it is not simply gross wages.

2026 reporting differs from the 2025 transition

The law added information-reporting requirements for qualified overtime. The IRS granted transition relief for 2025 because employer forms and systems were not ready to separately report the premium. That 2025 relief should not be assumed for 2026.

For 2026 planning, the calculator requires the reporting gate to be Yes. Reconcile the qualified amount on the employer or payer statement with pay stubs and the Schedule 1-A instructions. If several employers pay overtime, combine the qualified premiums once and preserve a worksheet by employer.

Social Security and Medicare still apply

Employee Social Security tax is generally 6.2% up to the 2026 wage base of $184,500. The calculator measures how much of the extra overtime pay remains under that base after the regular portion of the current check. If earlier wages already consume the base, the incremental Social Security amount is zero.

Regular employee Medicare tax is 1.45% without a wage cap. The optional 0.9% input can model Additional Medicare Tax on overtime dollars expected to fall above the applicable threshold. Employer withholding begins under a $200,000 per-employer wage rule, while final liability uses filing-status thresholds, so a full return can differ.

The Section 225 deduction reduces federal taxable income; it does not reduce Form W-2 Social Security or Medicare wages. This calculator never counts a payroll-tax saving from the deduction.

Using Form W-4 for current cash flow

Publication 15 explains that an employee may submit an updated Form W-4 so expected deductions affect federal withholding. That can move part of the expected filing benefit into paychecks rather than waiting for a refund. A W-4 change alters prepayment timing, not the legal deduction.

Do not subtract the deduction from gross overtime inside a payroll-tax calculation. Instead, estimate the annual deduction with Schedule 1-A, incorporate it into the W-4 deductions worksheet as instructed, and monitor year-to-date withholding. Life changes, a second job or a phaseout can make an early estimate too large.

Worked 2026 timecard example

The opening scenario uses a $30 regular rate, forty regular hours and ten overtime hours paid at time-and-a-half. Regular pay is $1,200 and overtime gross is $450. Estimated federal withholding of 22% is $99, state/local withholding of 5% is $22.50, Social Security is $27.90 and regular Medicare is $6.53 after rounding. The estimated extra cash is $294.08.

The potentially qualified FLSA premium is $150. Adding it to $5,000 previously reported produces $5,150, below the $12,500 nonjoint cap. MAGI of $140,000 is below the $150,000 threshold, so there is no phaseout. At a 22% marginal rate, the simplified annual federal benefit of the $5,150 deduction is $1,133.

Keep this timecard as the support for payroll cash flow and the qualified-premium amount.

Overtime review checklist

• Confirm the worker is covered and nonexempt under FLSA Section 7.
• Use the legal regular rate, including required bonus and differential adjustments.
• Separate straight-time wages from the FLSA-required premium.
• Exclude extra amounts owed only by state law, contract or employer policy.
• Combine 2026 reported premiums across employers under one return-level cap.
• Check MAGI, joint-filing and valid-SSN requirements.
• Treat withholding as a payment estimate and preserve FICA on overtime wages.
