Free Paycheck Calculator by State: Estimate 2026 Net Pay and Withholding

Net pay on the same $5,000 biweekly gross ranges from about $3,831 in Texas (no state income tax, no NJ-style program stack) to about $3,362 in New Jersey for a worker with a 5% 401(k) deferral. That's a roughly $470-per-paycheck swing driven by state income tax, state unemployment insurance, temporary disability insurance, family leave insurance, and city or local layers. None of it federal. Most paycheck calculators start from the same federal floor, then differ in how accurately they model state, local, and benefit-specific deductions. What separates a paystub that reconciles from one that doesn't is whether the seven deduction layers below are all present, in the right order, and anchored to each agency's 2026 rate publication.

This guide walks the seven layers in the order a state-specific paycheck reconciliation can be organized, with Priya Anand (a Hoboken product designer earning $130,000 a year paid $5,000 biweekly, contributing 5% to a traditional 401(k)) threaded through each one so the same gross ladders down to a reconciled net of $3,362.10. Without the 401(k) deferral, the same paycheck would land around $3,541.46.

A complete 2026 paycheck reconciliation usually contains:

• A federal income tax line computed from Publication 15-T percentage-method tables, not a hard-coded bracket
• A FICA Social Security line at 6.2 percent capped at the $184,500 wage base
• A FICA Medicare line at 1.45 percent on every dollar plus a 0.9 percent surtax above $200,000
• A state income tax line driven by the state's W-4 equivalent (NJ-W4, IT-2104, DE-4, MW507) and the agency's withholding tables
• A state disability or family leave line for the eight or nine jurisdictions that fund those programs out of the employee's check
• A local income tax line for cities, counties, school districts, and Act 32 districts in PA, OH, NY, MD, IN, KY, MI, MO, and AL
• Benefit and post-tax deduction lines (traditional 401(k), Section 125 health, Roth 401(k), garnishments) surfaced as visible stub lines that flow into final net. A pre-tax line that reduces an earlier tax base is subtracted only once from final net, not twice

Rates and wage bases drift every January, and a national calculator that hard-codes last year's figures can understate New Jersey deductions by $35-$45 per check or miss Washington's PFML and Cares LTC entirely. For a side-by-side model anchored to the agency publications, the MyStubs paycheck calculator keeps the 2026 rate matrix current with each state's most recent release.

#Why State Geography Moves the Net More Than the W-4 Does

The federal floor is identical from Miami to Missoula: Social Security at 6.2 percent up to the 2026 wage base of $184,500 per the SSA 2026 Contribution and Benefit Base, Medicare at 1.45 percent on every dollar, plus the marginal-bracket bite from IRS Publication 15-T. Layered on top is a state-by-state lattice of income tax, disability insurance, paid family leave, long-term-care premiums, local earned-income tax, and per-paycheck head taxes that can move net pay by eight to twelve percentage points between the cheapest and the most expensive states. Without the 401(k) deferral, a $5,000 biweekly gross nets roughly $3,831 in Texas and $3,541 in New Jersey once NJ income tax and the UI/WF/TDI/FLI stack come out. With Priya's 5% traditional 401(k), the New Jersey example reconciles to $3,362.10. Same $130,000 salary, thousands less take-home over a year, none of it federal.

Three buckets of state behavior drive the gap. Nine states levy no broad-based wage income tax. Ten states apply a flat rate to taxable wages above a small deduction. The rest run progressive brackets that mirror the federal structure, sometimes with marginal rates above ten percent. On top of those three buckets, a handful of states bolt on payroll-funded social insurance (California's SDI, New York's PFL, Washington's PFML and Cares LTC, Pennsylvania's EIT and LST, New Jersey's UI-WF-TDI-FLI quartet) that's technically not income tax but absolutely shows up as a deduction line. A calculator that skips these programs will overstate net pay by a few hundred dollars per check in NJ, CA, or WA, and miss the local layer entirely in PA and OH.

#The Seven-Layer Paycheck Stack

Each numbered layer below runs in the order a real payroll system applies it, starting from the gross wage and ending at net. Every layer is anchored to a primary-source publication on first mention, has an applicability list so readers know whether their paystub should show the line, and ties to Priya's $5,000 biweekly gross so the running deduction stack reconciles to a single net figure.

#1. Federal income tax

Federal income tax is computed from the percentage-method tables in IRS Publication 15-T, keyed to the 2020-vintage W-4. Form W-4 abandoned allowances and now collects dollar amounts: filing status, dependents in Step 3, other income in Step 4a, deductions in Step 4b, and extra withholding in Step 4c. Supplemental wages (bonuses, commissions, severance, retroactive raises) get either the aggregate method or the flat 22 percent (37 percent above $1 million in a calendar year). Most employers default to 22 percent because the bookkeeping is cleaner.

This layer applies to every W-2 employee, so the gating that fits sections 4-7 (state, local, deduction-by-deduction) is unnecessary here. The relevant nuance is when this layer moves: a W-4 update with new Step 3 dependent credits or Step 4c additional withholding, a switch to the supplemental method on a bonus run, or crossing into a new marginal bracket mid-year as cumulative YTD wages compound.

Priya files single with no dependents and no extra withholding, contributing 5% to a traditional 401(k). Her federal line is a function of the bracket she lands in at $123,500 of FIT-taxable annualized wages, not the gross $130,000. A worker who later adds a dependent in Step 3 or extra withholding in Step 4c will see this line move without anything else on the stub changing.

#2. FICA — Social Security

Federal income tax pulls $726.42 off Priya's gross. FICA layers two more lines on top, starting with Social Security. Social Security tax is 6.2 percent of wages up to the 2026 wage base of $184,500 per the SSA 2026 Contribution and Benefit Base. The wage base is a hard ceiling. Once year-to-date Social Security wages cross $184,500, the line goes to zero for the rest of the calendar year and the per-check net pay jumps by 6.2 percent of gross.

Use it when:

• You're a W-2 employee under the wage base year to date
• You haven't yet reached the $184,500 wage base
• You're a high earner approaching the base mid-year and want to model when the line drops out

At $130,000 annualized Priya never crosses the base. The line runs $310.00 on every one of her 26 biweekly checks. A peer earning $250,000 would see Social Security stop withholding around mid-November, and the last three or four checks of the year would visibly fatten. It's one of the few moments on a paystub when the math actually breaks in the worker's favor.

#3. FICA — Medicare + Additional Medicare

Social Security tops out at the wage base. Medicare doesn't, which is why high earners see this layer keep cutting after layer 2 stops. Medicare tax is 1.45 percent on every dollar of wages with no wage cap, plus an additional 0.9 percent Additional Medicare Tax on wages above $200,000 (single, head of household) or $250,000 (married filing jointly), both authorized by IRS Publication 15. Employers begin withholding the 0.9 percent surtax in the pay period in which year-to-date wages cross $200,000 regardless of filing status. The true-up against the joint threshold happens on the tax return.

Use it when:

• You're a W-2 employee (no exceptions other than narrow religious-order carve-outs)
• Your year-to-date wages have or will cross the $200,000 Additional Medicare trigger
• You receive a year-end bonus that pushes you across the trigger

Priya stays $70,000 below the Additional Medicare trigger, so only the base 1.45 percent runs. A colleague earning $260,000 would see the surtax kick in around early October once YTD wages cross $200,000.

#4. State income tax

Layers 1-3 are uniform from Maine to Hawaii. Layer 4 is where Priya's Hoboken paycheck starts diverging from a peer's in Houston or Tampa. State income tax is computed from the state's W-4 equivalent (NJ-W4, IT-2104, DE-4, MW507, MI-W4, and so on) against the agency's withholding tables. Priya's NJ withholding follows the New Jersey Department of the Treasury Division of Taxation employer payroll guidance, which publishes annual bracket-based tables. At $130,000 annualized she lands in the 6.37 percent marginal bracket against the NJ-W4 single-filer schedule.

Use it when:

• You work in or live in one of the 41 states (plus DC) with a personal income tax on wages
• You have a state W-4 equivalent on file (the employer defaults to the work-state rate without one)
• You work in a reciprocity pair (NJ-PA, IL with IA/KY/MI/WI, the mid-Atlantic cluster) and have filed the non-residency certificate

Priya is a New Jersey resident with a current NJ-W4 on file, so the withholding runs cleanly against the state schedule. If she switched to a remote arrangement with a Texas employer she'd still owe NJ tax on every dollar. Physical presence pulls the income to the state where the work is performed, and reciprocity doesn't apply. Note the $250 traditional 401(k) deferral reduces federal taxable wages but NOT NJ taxable wages. NJ is one of the small handful of states (CA, PA, NJ, MA partially) that doesn't conform to federal pre-tax 401(k) treatment. This is one of those quiet rules that surprises every NJ resident the first time they actually run the math.

#5. State disability + family leave (UI, WF, TDI, FLI in NJ)

State income tax in layer 4 is one line. Layer 5 is the additional employee-funded social-insurance stack that NJ, CA, NY, and WA bolt on top of it. New Jersey is one of the handful of states that splits unemployment, disability, and family-leave funding with the employee instead of carrying the whole load on the employer side. The 2026 rates published by the NJ Department of Labor & Workforce Development and the agency's MyLeaveBenefits employer guide put four separate employee-side lines on every NJ paystub: State Unemployment Insurance at 0.3825 percent and Workforce Development at 0.0425 percent on wages up to a $44,800 base, plus Temporary Disability Insurance at 0.19 percent and Family Leave Insurance at 0.23 percent on wages up to a separate, much-higher $171,100 base. California adds SDI at 1.30 percent on every dollar (no cap since SB-951). New York PFL runs at 0.432 percent in 2026 per the NY Workers' Compensation Board PFL premium notice. Washington PFML is 1.13% total in 2026, with employees paying 71.43% of the total premium at employers with 50+ employees (about 0.807% employee-side) up to the 2026 Social Security cap of $184,500 per the WA ESD Paid Leave premium publication. WA Cares LTC is separate at 0.58% of gross wages and isn't capped at the Social Security wage base per the Washington Cares Fund.

Use it when:

• You work in NJ, CA, NY, WA, RI, MA, CT, OR, CO, or any jurisdiction with an employee-funded SDI, PFL, PFML, or LTC program
• Your year-to-date wages have not exhausted the smaller UI base (and the line is still withholding even if state income tax runs against a higher threshold)
• You are a high earner watching one wage base hit mid-year while a separate base keeps the disability line running

Early in the year, the four NJ state-program lines together pull $42.26 off each check, a stack that doesn't exist for a peer in Florida or Texas. After Priya crosses the $44,800 UI/WF base (around her ninth check at the $5,000 biweekly run rate), the UI and WF lines stop, while TDI and FLI continue withholding through the much-larger $171,100 base. A calculator hard-coding NJ to a single "state withholding" line understates Priya's deductions by $42 per check early in the year and still misses $21 per check once the UI/WF base clears.

#6. Local income tax

Layer 5 is set at the state level. Layer 6 reaches one level further down, into the city, county, school district, or Act 32 jurisdiction that a generic calculator usually ignores. Local income tax is the layer national calculators most often skip. New York City levies a resident income tax of 3.078 to 3.876 percent across four brackets, administered by the NY Department of Taxation and Finance. Yonkers adds a 16.75 percent resident surcharge on the state-tax line. Pennsylvania runs Earned Income Tax through twenty-one Act 32 districts at one percent in most municipalities (up to 3.93 percent in Philadelphia) plus a Local Services Tax of about $52 a year, all administered through the PA DCED local income tax guidance. Ohio routes 600-plus municipal taxes through RITA or CCA per the Ohio Department of Taxation employer withholding page. Indiana counties levy 0.5 to 3.38 percent. Maryland counties and Baltimore City layer 2.25 to 3.2 percent on top of the state rate.

Use it when:

• You work in or live in a PA Act 32 district, an OH RITA/CCA municipality, NYC or Yonkers, an Indiana or Maryland county, a KY city or county with an occupational license fee, or Michigan's twenty-four city-tax cities
• The county or municipality of residence as of January 1 differs from your work jurisdiction (Indiana and Maryland lock the rate to January-first residency)
• You are a remote worker whose home and work jurisdictions sit in different Act 32 districts in PA

Hoboken sits in New Jersey, which doesn't authorize local wage income tax. Priya's local line is $0.00 and the running net stays at $3,362.10. A Pittsburgh resident/worksite example at the same gross can produce about $153.50 of EIT at a 3.07% combined rate (1% municipal plus 2.07% school district), plus roughly $2 per biweekly check of LST, depending on Act 32 PSD code and exemption status. An NYC resident at the same gross would see roughly $190 of city tax at the 3.876% top bracket on income above $50,000.

#7. Benefit and post-tax deduction lines

Layers 1-6 are tax lines set by federal, state, and local authorities. Layer 7 surfaces the deduction lines Priya herself elects (401(k), health, FSA, garnishments) that show on the visible stub. Some benefit deductions affect earlier tax bases even though they appear as deduction lines on the stub. For readability, this guide shows the 401(k) once in the tax-base calculation (layer 1) and again in the visible-line checklist (layer 7), but it's subtracted only once from final net. Pre-tax deductions reduce federal taxable wages and sometimes FICA wages too: traditional 401(k) contributions, Section 125 health and dental premiums, HSA contributions, FSA contributions, and qualified parking and transit per IRS Publication 15. Post-tax deductions come off after taxes have been computed: Roth 401(k) contributions, garnishments, union dues, charitable payroll deductions, and after-tax disability premiums. The IRS Tax Withholding Estimator models how a 401(k) election changes the federal line before payroll runs it.

Use it when:

• You have any employee benefit running through payroll: health, dental, vision, 401(k), HSA, FSA
• You're modeling a 401(k) deferral change and want to see the federal-tax impact before the next paycheck
• You have an active wage garnishment, child support order, or union dues line

Priya nets $3,362.10 on every biweekly check, keeping 67.2 percent of gross. The 5% 401(k) deferral threads through the calculation: it reduces federal taxable wages in layer 1 (saving roughly $60 of federal tax versus a no-deferral peer at this bracket) but NOT NJ taxable wages in layer 4. NJ doesn't conform to federal pre-tax 401(k) treatment, which is why the NJ tax line stays anchored to the full $5,000 gross. Without any 401(k) deferral, Priya's net would be $3,541.46 ($3,362.10 + $250 - $59.64 of additional federal tax she'd then owe). The deferral effectively shields $250 from federal tax at her ~24% marginal rate, saving about $60 per check while routing $250 to retirement: a $60 net benefit per check relative to a same-gross peer who takes the cash.

#What Counts as a 2026 Paycheck Deduction Line

Every line item on a real W-2 paystub maps to one of the seven layers above. The taxonomy below sorts the most common lines, the authority that sets them, and whether they affect FICA wages.

#How to Calculate 2026 Net Pay by State

Five methods cover almost every reader's reconciliation use case. Pick the row that matches the question being asked.

Two wrinkles to flag. A payroll system doesn't need to compute taxes in a literal visual order. It computes each tax from the correct wage base: FIT taxable wages, Social Security wages, Medicare wages, state taxable wages, and any program-specific wage base. A traditional 401(k) deferral reduces FIT-taxable wages but not FICA wages or NJ taxable wages. A Section 125 health premium reduces both FIT and FICA wages. The visual line order on the stub is convention, not arithmetic dependency. And the supplemental flat method tends to under-withhold federally for anyone in the 32 percent bracket or higher. A $25,000 RSU vest at the 22 percent supplemental rate leaves a structural balance due in April that's a payroll feature, not a payroll error.

#A New Jersey Six-Figure Paycheck Reconciled — Priya Anand, Hoboken

Priya's gross-to-net for the May 8, 2026 pay date, run through all seven layers in order:

The reconciliation matches Priya's actual paystub to the penny. The four NJ state-program lines pull $42.26 off every check: UI, WF, TDI, FLI, each with its own rate and wage base. If Priya took the same $130,000 salary to Austin (no state income tax, no NJ UI/WF/TDI/FLI), her net would rise by approximately $279 per check ($236.72 NJ income tax + $42.26 NJ programs), landing around $3,641. That's a roughly $7,250 annual swing on the same gross, all state-driven. NJ's non-conformance to federal 401(k) treatment means her NJ tax line is computed on the full $5,000, which is why it lands at $236.72 rather than the $225 it would be if NJ honored the federal pre-tax deferral.

For the gross-to-net pipeline run separately for each comparable state, see the gross-to-net pay calculator walkthrough; for the SMB side of running the same matrix across a multi-state team, the small-business payroll recordkeeping checklist covers the recordkeeping discipline that makes the reconciliation auditable.

#Common Mistakes That Skew the Paycheck Math

Paycheck-calculator misuses that produce a wrong net pay number on a real check:

• Using a national calculator that hard-codes 2023 or 2024 rates against a 2026 paystub (NJ TDI, CA SDI, WA PFML, and NYC brackets all moved)
• Plugging a 401(k) deferral into a calculator that applies it to NJ taxable wages (NJ doesn't conform; PA and CA also don't)
• Running a flat blended "effective rate" forward to project a salary change. Federal/state brackets are non-linear, so 30% on $130K projects wrong against $250K
• Treating the supplemental method's 22% federal flat as the worker's actual liability. It's a withholding shortcut, not the settled tax
• Running NJ without separating UI + WF + TDI + FLI into four lines (the UI/WF base $44,800 and the TDI/FLI base $171,100 are different)
• Running CA with SDI capped at the old $153,164 ceiling (cap removed since SB-951 took effect in 2024)
• Running WA without the Cares LTC 0.58% line for anyone who did not opt out during the 2021-2022 window
• Running an NYC resident's stub with only NY state tax and no city tax line (city tax adds roughly 3.5-3.9% on top)
• Running a PA paystub without the separate EIT line for the Act 32 home or work municipality
• Running PA without recognizing that LST is a flat $52/year head tax (pro-rated to $2/biweekly check, capped regardless of wages) while PA SUI 0.07% has no wage cap and continues all year
• Computing Social Security against gross after YTD has already crossed $184,500 (the line goes to zero for the rest of the year)
• Modeling Additional Medicare 0.9% surtax at the wrong $200,000 / $250,000 threshold (employer withholds at $200K regardless of filing status; the joint trigger trues up on the tax return)
• Pulling a "no state income tax" state and missing the WA PFML, NH interest-and-dividends, or TX-specific local quirks
• Reading the work-state withholding line in a reciprocity pair (NJ-PA, IL with IA/KY/MI/WI) without filing the non-residency certificate (NJ-165, REV-419, IL-W-5-NR)
• Assuming Indiana or Maryland county move mid-year changes withholding. Both states lock to January 1 county of residence

Honest mistakes that produce a wrong net but aren't fraud:

• Forgetting the new W-4 after a marriage, divorce, or second job. Step 3 and Step 4 entries go stale
• Treating the 22 percent federal supplemental rate as a final tax. It's a withholding shortcut, not a settled liability
• Forgetting that traditional 401(k) reduces federal taxable wages but not FICA wages, while a Section 125 health line reduces both
• Reading the work-state withholding line in a reciprocity pair (NJ-PA) without filing the non-residency certificate (NJ-165, REV-419)
• Assuming an Indiana or Maryland county move mid-year changes withholding. The rate stays locked to January-first county of residence
• Pulling a "no state income tax" state and missing the WA PFML, NH interest-and-dividends carryover, or TX-specific local-jurisdiction quirks
• Counting a one-time bonus toward the regular run rate when planning a 401(k) deferral increase

The fix for almost every item in the second list is the same: pull three consecutive paystubs, run the same gross through a state-specific calculator anchored to the agency publication, and flag any line that differs by more than a dollar. SDI, PFL, PFML, and EIT are usually the lines that drift, and the lines a national calculator most often hard-codes to last year's rate.

Copy, paste, and fill the bracketed fields. Use this when a paystub line doesn't match the seven-layer expectation and you want payroll to reconcile it without escalating to HR.

Priya used this template once when a January paystub showed NJ UI still withholding after she expected the $44,800 base to clear. Payroll confirmed the running YTD was $43,900 and the line dropped to zero on the next check. Two emails, no ticket.

#Example Paycheck Stack by State

The five-state matrix below runs the same $5,000 biweekly gross (Priya's exact paycheck) through five very different state systems so the structural gap is visible side by side. No 401(k) deferral for the comparison, so federal and state taxable wages start from the same $5,000 base across every column. Single-filer profile, no dependents.

The Texas-to-NYC gap on the same gross is roughly $490 per check, about $12,700 a year (figures are approximate; recompute with the 2026 Pub 15-T method for to-the-penny precision). Pennsylvania's EIT and LST footnote: the 3.07% PA state income tax is flat, the employee SUI at 0.07% has no wage cap ($3.50 per check continues all year regardless of YTD), while LST is a flat $52 annual head tax pro-rated to $2 per biweekly check (not a percentage rate, capped at $52 regardless of wages). That distinction matters because a $250,000 PA earner pays the same $52 LST as a $30,000 worker, while PA SUI scales linearly with wages forever. NYC at the same gross runs $189 of city tax: 3.078% to $12K + 3.762% to $25K + 3.819% to $50K + 3.876% above on the $130K resident. The $124.20 figure that appeared in a prior draft was wrong (it computed to ~2.76% which is below all four NYC brackets). That swing is the entire case for using a state-specific calculator anchored to the agency publications, not a generic national one. The MyStubs paycheck calculator keeps the 2026 matrix current with each agency's most recent release.

Run before the last paycheck of the calendar year:

When the year-end reconciliation is finished, two MyStubs tools tie it together. Use the paycheck tax calculator to model the next year's elections (401(k) deferral percent, FSA balance, W-4 dollar entries) before they go to payroll. Use the paystub generator to reconstruct stubs from a prior W-2 employer when current stubs are missing. It's a layout instrument for wages an employer actually paid, not a way to invent wages that were never earned.

#Remote and Reciprocity Quirks

A remote worker physically in Oregon working for a Texas employer owes Oregon tax under physical presence. Texas has no work-state withholding to credit against. Six states (Connecticut, Delaware, Nebraska, New Jersey, New York, Pennsylvania) apply a convenience-of-the-employer rule that pulls remote workers back into the employer's state unless the arrangement is for the employer's, not the employee's, convenience. Reciprocity pairs (NJ-PA, IL with IA/KY/MI/WI, and the mid-Atlantic cluster around MD/PA/VA/WV) let an employer withhold for the home state instead of the work state, but only if the employee files the non-residency certificate (NJ-165, IL-W-5-NR, PA's REV-419) on the first day. Without the form on file, the employer must default to the work-state rate and the employee chases the credit at filing time. New York's IT-2104 nineteen-line allowance form, the Yonkers 16.75 percent surcharge derived from the state-tax line rather than gross wages, and the Indiana/Maryland January-first county-of-residence lock are the four wrinkles a generic calculator most often gets wrong on a multi-state file.
