Massachusetts: flat PIT used as supplemental estimate

Massachusetts has a flat personal income tax and no separate supplemental percentage in our source set.

When a bonus is paid separately, many payroll systems withhold near the flat PIT of 5%. That is the educational estimate shown here.

County or local add-ons (where any) are not included.

How Massachusetts payroll usually handles bonuses

When the bonus is paid separately, many employers apply ~5% PIT state rules plus federal 22% and FICA.

If the bonus is combined with regular wages, withholding may follow the aggregate method instead of these flat percentages (IRS Pub. 15 §7).

Employees should reconcile annual liability on Form 1040 — paycheck withholding is only an estimate.

How withholding scales with bonus size

At a constant rate, state tax scales roughly linearly: double the bonus and state withholding roughly doubles (before exemptions or method changes).

Above $1M supplemental wages in a year with one employer, federal withholding jumps to 37% on the excess (Pub. 15).

What this profile does not include

Local city or municipal wage taxes (for example NYC resident tax, Philadelphia wage tax, Ohio city income tax) are not in these figures.

California SDI, state disability, paid family leave premiums, and local school taxes are outside the supplemental income-tax line.

Confirm current employer guides linked in the sources section before relying on a stub estimate.

Massachusetts bonus tax FAQs

Massachusetts has no separate supplemental table; our educational estimate uses the state’s flat PIT ≈5% (~$500 on $10,000 bonus with $80,000 year-to-date wages (flat supplemental method)).

On the vignette ($10,000 bonus, $80,000 YTD): about $3,465 total withheld ($2,200 federal + $765 FICA + $500 state), leaving ~$6,535 net (65.35% of gross).

With $80,000 year-to-date wages, a $5,000 bonus nets about $3,267.50 after roughly $1,732.50 withheld ($250 state).

With $80,000 year-to-date wages, a $25,000 bonus nets about $16,337.50 after roughly $8,662.50 withheld ($1,250 state).

With $80,000 year-to-date wages, a $50,000 bonus nets about $32,675 after roughly $17,325 withheld ($2,500 state). Enter your exact bonus and YTD wages at /bonus-tax-calculator/massachusetts for a personalized estimate.

Not necessarily. Flat 22% federal supplemental withholding (and 37% on supplemental wages over $1 million per employer per year) is a paycheck rule under IRS Publication 15. Your true federal tax depends on total annual income, deductions, and credits when you file Form 1040 — you may owe more or get a refund. Massachusetts state withholding at 5% is likewise an estimate against your full-year state liability.

Supplemental flat rates are a payroll shortcut when bonuses are paid separately. Employers may instead use the aggregate method (combine with regular wages). Confirm with payroll and your state withholding tables.

Usually yes under the flat supplemental method — signing, retention, and annual bonuses are all supplemental wages. Timing and whether payroll combines the payment with regular wages (aggregate method) can change the paycheck stub.

About $2,200 (22% flat) on this vignette — the same federal amount as in every other state — plus about $765 FICA (6.2% Social Security + 1.45% Medicare, subject to wage-base and Additional Medicare rules). The gap vs other states is almost entirely state supplemental withholding.

Social Security tax (6.2%) only applies until wages reach $184,500 in 2026. If year-to-date earnings plus the bonus cross that wage base, SS withholding on the bonus can be partial or zero. Medicare (1.45%) still applies with no wage base; an extra 0.9% Additional Medicare Tax can apply once wages exceed $200,000 for single filers (withholding threshold). Use /bonus-tax-calculator/massachusetts and the YTD field to model your situation.

Massachusetts ranks #21 of 51 jurisdictions for state supplemental withholding on the $10,000 vignette (~$500 state tax at 5%). Rank #1 is the highest state tax on that vignette.

Massachusetts withholds about $500 more in state tax than Texas ($0) on this vignette, so net take-home is about $500 lower ($6,535 vs $7,035). Federal and FICA are the same on the vignette.

It depends on your marginal federal bracket and full-year return. If your federal bracket is below 22%, flat supplemental withholding often over-withholds and you may get a refund. If your bracket is above 22%, you may owe more at filing. The same idea applies to Massachusetts state tax versus what was withheld at 5%.

This estimate covers Massachusetts state supplemental withholding (or $0 if none) plus federal and FICA. Local city wage taxes are not included unless your employer withholds them separately.

A gross-up means the employer increases the gross bonus so that after withholding you still receive a target net amount. Because Massachusetts adds about 5% state supplemental withholding, the gross needed to deliver a given net is higher than in no-tax states like Texas. Ask HR whether an offer is net or gross before you accept.

Under IRS Publication 15, supplemental wages over $1 million from the same employer in the same calendar year are withheld at 37% (mandatory flat rate) on the excess, while the first $1 million can use the 22% flat method. The $1 million threshold is per employer, per year — not combined across employers. Massachusetts state rules still apply on top.

Usually no under the flat supplemental method — both are supplemental wages. Timing and whether pay is combined with regular wages can change the stub via the aggregate method.

State income tax withheld may be itemized on Schedule A subject to the federal SALT cap. Whether you benefit depends on your full return.

About $2,200 (22% flat), the same as in every other state on this vignette — plus about $765 FICA.
