Connecticut Overtime Tax Calculator 2025 | Federal OBBBA Savings Estimate

Estimate your federal overtime premium deduction (and possible tax impact) under the 2025 proposal, with Connecticut-specific context and official sources.

Connecticut context:

This calculator estimates a potential federal overtime-related savings scenario under the 2025 proposal. State and local tax outcomes depend on Connecticut rules and your full household picture, so use the official sources below to validate what applies to you.

Model assumptions used in this calculator

Overtime “premium” is modeled as 0.5× your hourly rate per overtime hour (the time-and-a-half premium portion).
Annual cap: 2,500 (single) / $25,000 (married filing jointly).
Phase-out starts at MAGI 50,000 (single) / $300,000 (MFJ), reducing the deductible amount by 00 per ,000 over the threshold.
If MAGI is blank, it’s estimated from your weekly pay and overtime scenario.

How to Use This Estimate for Planning

Overtime can materially change take-home pay in Connecticut, especially for defense manufacturing, healthcare staffing, and services. This tool focuses on the federal side of the proposal: it models a capped overtime “premium” amount and then applies an income phase-out based on filing status and estimated household income (MAGI). The output is an estimate meant to help you compare scenarios (for example: “What if I work 6 more OT hours per week?”), not a guarantee of your final tax filing result.

If you leave MAGI blank, the calculator estimates it from the entered weekly pay and overtime scenario. If you know your approximate household income, entering MAGI can reduce surprises because phase-out behavior is driven by that number. Either way, remember that real returns can differ based on deductions, credits, and how a final law is written and implemented.

What to confirm (and where)

Connecticut Department of Revenue Services: state income tax and withholding rules (if applicable), definitions, and current guidance.
IRS tools: whether a W-4 update makes sense after you model a scenario here.
Your pay stub: how overtime is computed and reported for your specific job (rules can vary by employer and pay type).

A practical workflow is: (1) model a few overtime scenarios here, (2) check official guidance, and (3) only then adjust withholding if you’re confident the change is appropriate.

Possibly. If your overtime or income changes, re-check federal withholding using IRS tools and review Connecticut guidance so your paycheck withholding and filing assumptions stay consistent.

How to use this estimate in Connecticut

Three common use cases to help you decide what to check next (federal estimate only; state rules can differ).

Use case 1: paycheck withholding sanity‑check

Use this estimate to set expectations, then confirm your withholding still matches your situation using the IRS Withholding Estimator. Our calculation notes explain what is (and is not) included.

Use case 2: moved, part‑year, or multi‑state work

If you moved, work across state lines, or file part‑year, confirm residency and withholding guidance before relying on a federal-only estimate. Start with the official Connecticut guidance, then use our state checklist. See how we use sources.

Use case 3: planning & documentation

If you’re sharing this estimate with an employer or preparer, note how your overtime is calculated on your paystub. Review assumptions & limits and the disclaimer. You can also browse all states for comparisons.

Mini how-to by work situation in Connecticut

A federal-only estimate can still help planning. Connecticut generally has state-specific withholding and filing rules, so use the official state guidance to confirm residency/part‑year issues and how state withholding is calculated. Use official tools like the IRS Withholding Estimator, review Form W‑4, and check official Connecticut tax guidance.

Hourly / shift workers

If your overtime hours fluctuate week to week, use the IRS Withholding Estimator after a typical pay period so your federal withholding stays aligned with your current pattern. Then review your Form W‑4 choices and keep recent pay stubs handy when you compare results. Connecticut may apply state-specific withholding and residency rules, so confirm local guidance before making changes. Official links: IRS estimator, Form W‑4, Connecticut tax guidance.

Salaried with overtime

If you’re salaried but occasionally earn overtime or bonuses, treat this estimate as a planning signal and validate your withholding using the IRS tool. If the estimate suggests a meaningful change, consider updating your W‑4 and ask payroll how overtime is coded on your pay statement. Connecticut may apply state-specific withholding and residency rules, so confirm local guidance before making changes. Official links: IRS estimator, Form W‑4, Connecticut tax guidance.

Multiple jobs or job change

If you have more than one job (or you changed jobs mid‑year), withholding can get out of sync quickly. Run the IRS estimator with combined income, then check whether each employer’s withholding settings are consistent with the estimator’s guidance. State withholding rules in Connecticut can differ from federal expectations—double‑check residency/part‑year guidance on the official site.
