Massachusetts Biweekly Paycheck Calculator 2026

Here is exactly what your biweekly paycheck looks like in Massachusetts at common annual salary levels in 2026. Calculated for a single filer, standard W-4, biweekly pay frequency, no pre-tax deductions.

Single filer · standard W-4 · biweekly pay (26 periods/yr) · no pre-tax deductions · 2026 IRS withholding tables · Massachusetts published 2026 withholding method. Actual paychecks vary based on filing status, allowances, and deductions.

Massachusetts withholds state income tax from every paycheck. Your biweekly paycheck includes these deductions:

• Federal income tax (2026 IRS withholding tables)
• Massachusetts state income tax (withheld each pay period)
• Social Security tax — 6.2% on wages up to $184,500
• Medicare tax — 1.45% on all wages
• Employee benefit deductions

A biweekly pay schedule means you receive a paycheck every two weeks — 26 paychecks per year. To find your gross biweekly pay, divide your annual salary by 26:

Two months per year you will receive three biweekly paychecks instead of two. This is sometimes called a "three-paycheck month." Because benefit deductions are often fixed per paycheck, the extra check can feel larger than usual.

Your net biweekly paycheck in Massachusetts depends on your annual salary, W-4 filing status, Massachusetts state withholding elections, retirement contributions, health insurance deductions, and any additional withholding.

The Paid Family and Medical Leave employee contribution is withheld on wages up to $184,500, the same base the calculator above uses for Social Security. For a biweekly earner above that level, both deductions end on the same paycheck late in the year and the deposit visibly jumps.

Below the base the PFML line is a flat percentage of every check, all 26 periods. The employee share is entered in the calculator because employers with approved private plans may withhold a different amount, and some employers cover part or all of the employee portion.

Massachusetts levies an additional 4% surtax on annual income above $1 million on top of its flat rate. For a biweekly earner whose salary crosses that threshold, withholding can step up partway through the year rather than applying evenly across all 26 checks.

This makes Massachusetts one of the few states where the late-year paychecks are proportionally smaller than the early ones for high earners — the opposite of the pattern created by Social Security and PFML ceilings. The two effects work against each other, and which one dominates depends on where your income sits.

Massachusetts maintains no reciprocal agreements. It taxes income earned from work physically performed in Massachusetts regardless of residence, which is why a large number of New Hampshire residents have Massachusetts tax withheld from all 26 biweekly checks despite living in a state with no income tax.

New Hampshire offers no credit, because it has no income tax against which one could be claimed. For a New Hampshire resident the entire Massachusetts deduction is a real cost, and the deciding factor is where you physically work on scheduled days.
