MA State Tax Withholding Requirements

Massachusetts uses a pay-as-you-go system for income taxes, where tax is collected from wages throughout the year. This process, known as withholding, ensures tax obligations are met gradually with each paycheck rather than in a single, large payment. The system applies to wages paid to residents for services performed inside or outside the state, and to nonresidents for services performed within Massachusetts.

Completing the Employee Withholding Form (M-4)

To set up your state tax withholding, you must complete the Massachusetts Employee’s Withholding Exemption Certificate, known as Form M-4. This document instructs your employer on how much money to withhold from your paycheck for state income taxes based on your filing status and exemptions.

The core of the Form M-4 involves claiming withholding exemptions, which reduce the amount of your taxable income. You are entitled to a personal exemption for yourself and an additional one if your spouse does not claim their own. You can also claim exemptions for each qualified dependent.

Further exemptions are available based on age and other circumstances. An additional exemption can be claimed if you or your spouse will be 65 or older by the end of the year. There is also an exemption available for blindness.

If you anticipate a more complex tax situation, such as significant non-wage income or large deductions, you can request that your employer withhold an additional amount from each paycheck. This is done by entering a specific dollar amount on the designated line of the Form M-4. The official form is available on the Mass.gov website.

Employer Calculation and Remittance Responsibilities

Once an employee submits a Form M-4, the employer uses that information to calculate the state income tax to withhold. The employer consults the official withholding tables provided by the Massachusetts Department of Revenue, using the employee’s wage amount, pay frequency, and exemptions to determine the tax to be withheld.

Withheld funds must be sent to the Department of Revenue electronically through the state’s online portal, MassTaxConnect. All new businesses are required to file and pay their withholding taxes electronically, regardless of the total amount.

The frequency of these payments depends on the total amount of tax the employer expects to withhold over the year.

• Employers withholding more than $25,000 annually must pay on a quarter-monthly basis.
• Those withholding more than $1,200 but not more than $25,000 annually must pay monthly.
• Employers withholding more than $100 but not more than $1,200 annually must pay quarterly.
• If the total annual withholding is expected to be $100 or less, a single payment is due by the end of January of the following year.

Withholding on Non-Wage Income

State tax withholding can also apply to income other than regular wages, such as payments from pensions, annuities, and other retirement plans. Individuals receiving this type of income can choose to have state income tax withheld voluntarily to manage the tax obligation throughout the year.

To initiate this voluntary withholding, the recipient must complete and provide Form M-4P, the Massachusetts Withholding Exemption Certificate for Pension, Annuity and Other Payments, to the payer of the income. This form instructs the payer on how much tax to withhold from each distribution.

This process is useful for managing tax liabilities on significant retirement distributions. By opting for voluntary withholding, retirees can avoid the need to make large estimated tax payments or face a substantial tax bill when they file their annual return. The responsibility lies with the income recipient to request this withholding.

Adjusting Your State Tax Withholding

You may need to adjust your state tax withholding in response to changes in your personal or financial situation. Common life events such as getting married or divorced, having a child, or a change in dependents can alter your tax liability. An adjustment may also be appropriate if you consistently receive a large tax refund or owe a significant amount of tax each year.

To make a change, you must complete and submit a new Form M-4 to your employer. You can request a new form from your human resources or payroll department at any time during the year. There is no need to wait for a specific enrollment period to make these changes.

Once you provide the updated Form M-4, the adjustments to your withholding will take effect on an upcoming pay cycle. You do not need to explain the reasons for the change to your employer.
