Pennsylvania Paycheck Calculator 

Pennsylvania keeps paycheck math brutally simple: a flat 3.07% personal income tax on gross compensation, unchanged since 2004, with no standard deduction, no brackets, and no break for 401(k) contributions. That last quirk surprises people: unlike the federal government, Pennsylvania taxes the money you defer into a 401(k). This Pennsylvania paycheck calculator runs the full 2026 math, including the 2026 federal brackets, FICA, and that 3.07% flat rate applied the Pennsylvania way.

Quick Answer

The 401(k) quirk, explained

For federal purposes, a 5% 401(k) contribution on $75,000 ($3,750) reduces your taxable wages to $71,250, and after the $16,100 standard deduction your federal taxable income is $55,150. Pennsylvania ignores all of that. The Pennsylvania Department of Revenue levies 3.07% on gross compensation as the state defines it, and that definition includes employee deferrals to 401(k), 403(b), and 457 plans. Your W-2 shows the split: box 1 (federal wages) is lower, box 16 (state wages) is the full $75,000.

The quirk cuts both ways, and the comparison proves it. Run the same $75,000 salary with a 0% 401(k) and the calculator gives $59,290 of annual take-home pay: higher cash in hand, because nothing is deferred, even though federal tax rises to $7,670. With the 5% contribution, cash take-home falls to $56,365, but you hold $3,750 in retirement savings, for $60,115 kept in total. The 401(k) leaves you $825 ahead overall, because the federal tax saving ($7,670 minus $6,845) is real money even though Pennsylvania taxes the contribution anyway. Skipping the 401(k) to dodge the state tax would be backwards: Pennsylvania’s $115 of tax on the $3,750 deferral (3.07% of $3,750) is far smaller than the $825 federal saving. To see what a raise would do to every one of these layers, try our salary raise calculator, or compare the whole paycheck picture with our take-home pay calculator.

What the 2026 federal figures are

The federal side of the calculator uses the 2026 figures from IRS Revenue Procedure 2025-32: standard deductions of $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household, with seven marginal rates from 10% to 37%. The single brackets run $12,400, $50,400, $105,700, $201,775, $256,225, and $640,600 as the upper limits of each band; the joint and head-of-household schedules differ in the middle bands (for example, the head-of-household 24% band ends at $201,750, not $201,775), and the calculator carries each schedule exactly rather than doubling the single figures. Social Security tax is 6.2% on wages up to the 2026 wage base of $184,500, for a maximum employee tax of $11,439; Medicare is 1.45% on all wages, plus the 0.9% additional Medicare tax on wages above $200,000 for single filers and $250,000 for joint filers. The calculator now shows that additional Medicare amount as its own breakdown row whenever it applies, so the displayed rows always add up to the net: previously it was folded into the net with no visible line, which made high-salary breakdowns look wrong by exactly the missing amount.

Statewide only: what this page leaves out

This is a statewide Pennsylvania paycheck tool, and the distinction matters. The 3.07% line is the state tax only. Almost every Pennsylvania municipality levies its own earned income tax, commonly around 1%, collected through employers alongside the state withholding, and Philadelphia adds its own city wage tax on top of both (residents 3.735%, nonresidents 3.425%). None of that local tax is in this calculator’s state line, so if you work in Philadelphia your actual net will be lower than the figure here: use our Philadelphia paycheck calculator for the city layer instead of copying a city rate into a statewide estimate. The same warning applies in reverse: do not use the Philadelphia tool for a statewide estimate, because it adds a city tax most Pennsylvanians never owe. Health insurance premiums, HSA contributions, and other employer deductions are also excluded, as is the temporary federal deduction for qualified overtime pay added for 2025 through 2028, which is claimed on your return rather than in withholding.

Pennsylvania against a no-tax state

Same $75,000 salary, single filer, biweekly, 5% 401(k), with only the state line changed. In a state with no personal income tax, the same inputs keep $58,667.50 a year: the $56,365 Pennsylvania figure plus the $2,302.50 state tax. That $2,302.50 is the entire statewide cost of Pennsylvania’s income tax at this salary, and it is the number to use when comparing offers across state lines. It is also why the flat rate can mislead in both directions: 3.07% looks low next to a 5% top bracket elsewhere, but with no standard deduction it applies to every dollar, while a progressive state taxes only the dollars above its deduction and lower bands. Run the same salary through our Texas paycheck calculator to see the no-tax comparison in full, and if a move or a raise is on the table, the paycheck increase calculator shows what the raise does to each layer before you accept it.

What most Pennsylvania paycheck calculators get wrong

The classic error is treating Pennsylvania like other states: subtracting the 401(k) before applying the state rate, or applying a standard deduction that does not exist. Both mistakes understate the state tax, and at least one ranking competitor compounds the second error by labelling its state line as taxable income after a state standard deduction, a deduction Pennsylvania simply does not have. The second error is stale federal figures: calculators still running 2024 or 2025 brackets and the old $176,100 Social Security wage base produce take-home estimates that are off by hundreds of dollars a year. The third is silence about local tax: a calculator that shows only the 3.07% leaves Philadelphia and Pittsburgh workers wondering why their actual net is lower. This calculator applies 3.07% to gross wages including deferrals, uses the full 2026 federal figures from Revenue Procedure 2025-32, shows the additional Medicare row when it applies, and flags the local-tax gap explicitly instead of pretending the state line is the whole story. Lower-income filers may also qualify for Tax Forgiveness on Schedule SP, which can reduce or eliminate the 3.07% liability at filing time; it does not change withholding during the year, so it is noted here rather than built into the estimate.
