Use gross-to-net for a planned taxable cash bonus or net-to-gross for a promised take-home amount. Federal presentation and the payer's Maine method are separate facts.

Gross bonus amountEnter the taxable bonus to be paid.

Federal withholding methodThe calculator automatically suppresses the flat federal method when the facts do not qualify.

Federal supplemental-wage presentationThis controls federal flat-method eligibility only. Maine's separately-paid test and payer election are selected below.

Maine withholding settings

Maine withholding profileExempt and manual profiles require current records. Maine's income-tax, PFML, and UI sourcing tests are not interchangeable.

Maine bonus withholding methodUse 5% only when the bonus is paid separately and the payer elects that permitted method. Otherwise use combined pay, or the manual profile for a reviewed payroll amount.

W-4ME withholding status

W-4ME allowancesEach 2026 allowance is $5,300 in the published percentage method.

Manual Maine withholding for this bonusUsed only by the manual profile for other-state offsets, allocation, or payroll review.

Extra Maine withholding on this bonusAdded once. A normal W-4ME per-paycheck additional amount cancels from the same-pay incremental difference.

2026 return status - surcharge warning only

Estimated 2026 Maine taxable income before bonusUsed only to flag the new 2% surcharge. It does not alter published payroll withholding.

High-income limitation. The new 2% surcharge is a final-return tax on Maine taxable income above $750,000, $1 million, or $1.5 million depending on filing status. No revised employer withholding method was posted by the research cutoff, so the surcharge is disclosed but not added to payroll withholding.

What changed this estimate

What this Maine calculator gets right

Payment presentation controls Maine withholding

Separately paid supplemental wages may use 5%; a same-pay bonus is included with regular wages under the published percentage method.

Payroll withholding is not final tax

The July 29 high-income surcharge and return-level deductions are not substituted into an unrevised employer table.

Employee and employer amounts stay separate

PFML can affect take-home; UI, CSSF, UPAF, FUTA, and employer FICA stay outside it.

Maine bonus withholding FAQ

Does Maine tax every bonus at 5%?

No. Five percent is a permitted separate-payment withholding method. Same-pay bonuses use the regular-period method, and final income tax is reconciled on the return.

Why do W-4ME allowances sometimes not change the result?

The optional 5% separate-payment method does not use allowances. Status and allowances matter when a bonus is included with regular pay.

What changed on July 29, 2026?

Maine enacted a 2% surcharge on Maine taxable income above filing-status thresholds. The posted employer booklet has not yet been revised, so this calculator warns rather than guessing.

Can Maine PFML reduce the net bonus?

Yes, if the employer deducts an employee share. The employee payroll rate can range from 0% to 0.5% of covered wages depending on policy and plan.

Does Maine unemployment reduce take-home?

No. UI, CSSF, and UPAF are employer-side. Bonuses are wages through the $12,000 annual base.

Are Maine local wage taxes included?

No local wage-income withholding tax was identified in the official 2026 payroll materials reviewed, so no locality selector or local deduction is modeled.

Can the calculator gross up a promised net bonus?

Yes. Net-to-gross mode solves to the cent against the selected federal method, Maine withholding, FICA, and the employee PFML share.

Disclaimer: This calculator provides 2026 payroll estimates for regular taxable cash bonuses paid to W-2 employees based on standard federal withholding guidelines, Maine Revenue Services rules (including the optional 5% flat separate-payment method), and Maine Paid Family and Medical Leave (PFML) contribution rates. Actual paycheck results may vary based on Form W-4ME filing status and allowances, employee PFML premium shares, FICA wage caps and Additional Medicare thresholds, or assigned employer unemployment insurance and assessment rates (CSSF/UPAF). Please note that while a 2% high-income surcharge was enacted on July 29, 2026, it is a final-return tax and is not incorporated into posted employer withholding tables. These calculations are offered strictly for planning and illustrative purposes and do not constitute formal tax, legal, or accounting advice; employers should verify current state withholding instructions, plan documents, and employee payroll records prior to issuing checks.
