Massachusetts parents ordered to pay child support must send all payments through the Department of Revenue (DOR) Child Support Enforcement Division, not directly to the other parent. Under MGL c. 208 § 28, the state processes approximately 300,000 child support cases annually, collecting over $600 million in support payments each year. This guide explains all six payment methods available in 2026, including the new digital wallet options like Venmo and PayPal that Massachusetts added to make payments more convenient.

Understanding How to Pay Child Support in Massachusetts Through DOR
Massachusetts requires all child support payments to flow through the Department of Revenue Child Support Enforcement Division, which serves as the State Disbursement Unit (SDU) for the Commonwealth. Parents cannot pay child support directly to the other parent when a court order exists because DOR tracks all payments, maintains records for both parties, and ensures accurate accounting of support obligations. The DOR collected over $630 million in child support during fiscal year 2024, serving more than 250,000 families across Massachusetts according to the Child Support Enforcement annual report.
When a judge issues a child support order under the 2025 Massachusetts Child Support Guidelines effective December 1, 2025, the order automatically includes a provision for immediate income withholding unless the court specifically suspends this requirement. The DOR then issues an Order/Notice to Withhold Income for Child Support to the paying parent's employer. Parents who are self-employed, unemployed, or whose employers have not yet set up withholding must use one of the alternative payment methods described below until automatic deductions begin.
Six Methods to Pay Child Support in Massachusetts
Massachusetts DOR accepts child support payments through six primary methods: wage withholding, online portal payments, credit card phone payments, mail payments, MoneyGram cash payments, and digital wallet transfers. Each method has different processing times, fees, and requirements that parents should understand before selecting their preferred payment approach.
Wage withholding remains the most reliable method because employers deduct payments automatically and forward them to DOR within 7 business days of each pay period. Online payments through ma.smartchildsupport.com typically post within 2-3 business days. MoneyGram cash payments reach DOR within 3 business days at thousands of locations including Walmart, CVS, and Shaw's stores throughout Massachusetts. Credit card payments incur a convenience fee of approximately 2.5% of the transaction amount.
Wage Withholding: The Primary Payment Method
Wage withholding through income assignment is the default and most common method for paying child support in Massachusetts, processing over 75% of all child support collections statewide. Under MGL c. 119A § 12, when DOR notifies an employer of a child support order, the employer must begin withholding within the first pay period that occurs at least 14 days after receiving the notice. The employer deducts the ordered amount from each paycheck and sends the payment directly to DOR, which then disburses funds to the custodial parent.
Massachusetts law caps income withholding at 50% of disposable earnings for parents currently supporting another spouse or children in their household, and 60% for those without additional dependents. If a parent falls more than 12 weeks behind on payments, these limits increase to 55% and 65% respectively to help collect arrears faster. Disposable earnings include all forms of periodic compensation, not just wages, including payments to independent contractors, bonuses, commissions, and severance pay. Employers who fail to comply with income withholding orders face penalties of up to $100 per violation plus liability for the uncollected support amount.
Online Payment Portal: ma.smartchildsupport.com
The Massachusetts Child Support Internet Payment Website at ma.smartchildsupport.com allows parents to make one-time or recurring payments using credit cards, debit cards, or digital wallets including Venmo, PayPal, Apple Pay, and Google Pay. Parents must create an account using their DOR-issued 10-digit Personal Identification Number (PIN) found on billing statements or other DOR correspondence. As of June 5, 2025, all users must access the portal through a MyMassGov account with multifactor authentication rather than the previous direct login system.
To set up online payments, parents need their 10-digit PIN, a valid government-issued ID for identity verification, and a payment method. The portal accepts American Express, MasterCard, Visa, Discover, JCB, and Maestro cards. Convenience fees apply to credit card transactions, typically 2.5% of the payment amount, though the exact fee displays before completing any transaction. Parents who lost their PIN can retrieve it online by providing their date of birth or by calling Customer Service at (800) 332-2733.
Credit Card Payments by Phone
Parents who prefer not to use the online portal can pay child support by phone using a credit or debit card by calling (855) 449-2859 for the automated payment system, (800) 332-2733 for statewide customer service, or (617) 660-1234 for Greater Boston area callers. The phone system accepts Visa, MasterCard, and Discover cards. Parents need their PIN and the last four digits of their Social Security Number to complete phone transactions.
Phone payments process within 2-3 business days and appear on the paying parent's DOR account once posted. The same convenience fee that applies to online credit card payments applies to phone payments. Customer service representatives are available Monday through Friday from 8:30 AM to 4:30 PM Eastern Time for parents who need assistance or have questions about their payment status or account balance.
Mail Payments with Check or Money Order
Parents can mail child support payments by check or money order made payable to Commonwealth of Massachusetts to DOR/CSS P.O. Box 55144, Boston, MA 02205-5144. Every mailed payment must include a payment identification stub to ensure proper credit to the correct case. Payment stubs are included with monthly billing statements, and parents who need additional stubs can request them through the online portal or by calling customer service.
Mailed payments typically take 5-10 business days to process depending on postal delivery times and DOR processing volume. Parents should never send cash through the mail and should retain copies of all checks and money orders for their records. If a payment is lost or misapplied, proof of payment helps DOR locate and properly credit the funds. Parents who pay by mail should allow extra time before payment due dates to avoid late penalties.
MoneyGram Cash Payments at Retail Locations
Parents who prefer to pay in cash can make child support payments at thousands of MoneyGram locations throughout Massachusetts, including Walmart, CVS, Shaw's, and other participating retailers. To ensure the payment reaches DOR correctly, parents must use Receive Code 14664 when making the transaction. Parents also need their DOR-issued PIN to complete MoneyGram payments.
MoneyGram payments typically reach DOR within 3 business days of the transaction. MoneyGram charges a fee for this service, usually $3.99 to $7.99 depending on the payment amount and location. This option provides flexibility for parents without bank accounts or those who prefer cash transactions, though the fees make it more expensive than wage withholding or direct bank transfers over time.
Digital Wallet Payments: Venmo, PayPal, Apple Pay, and Google Pay
Massachusetts added digital wallet payment options in 2024, allowing parents to pay child support through Venmo, PayPal, Apple Pay, and Google Pay directly through the ma.smartchildsupport.com portal. These payments link to a parent's existing digital wallet account and process like standard credit or debit card transactions through the portal. Parents must first create or link their MyMassGov account to access these payment options.
Digital wallet payments offer convenience for parents who already use these platforms for other financial transactions. The same processing times and fees that apply to credit card payments apply to digital wallet transactions. Parents should verify that their digital wallet account has sufficient funds or a linked funding source before initiating payments to avoid declined transactions or overdraft fees from their bank.
How Custodial Parents Receive Support Payments
Custodial parents receiving child support in Massachusetts have two options for receiving payments from DOR: direct deposit to a bank account or the DOR Child Support Card, a VISA-branded prepaid debit card. Direct deposit typically provides the fastest access to funds, with payments usually available within 1-2 business days after DOR processes the incoming payment. Parents can set up direct deposit through their MyMassGov account or by contacting DOR customer service.
The DOR Child Support Card provides an alternative for parents without bank accounts or those who prefer not to use direct deposit. The card works like a standard debit card, allowing cash withdrawals from ATMs throughout Massachusetts and purchases anywhere Visa is accepted. DOR automatically sets up a Child Support Card for customers who have not enrolled in direct deposit. Card users should be aware of potential ATM fees charged by machine operators, though many banks offer fee-free ATM access for basic transactions.
Late Payment Penalties and Enforcement Actions
Massachusetts DOR applies a 0.5% interest rate and 0.5% penalty rate monthly on late child support payments exceeding $500 in arrears, meaning a parent who is $10,000 behind accumulates $100 in interest and penalties each month. These charges compound over time, significantly increasing the total amount owed. Parents who make their minimum required payment each month avoid penalties and interest for that period, even if they have an outstanding balance from prior months.
DOR employs multiple enforcement tools against parents who fail to pay child support as ordered. Initial enforcement typically begins with increased wage withholding up to the legal maximum of 65% of disposable income. DOR can also intercept federal and state tax refunds, place liens on real estate and personal property, seize bank accounts through administrative levy, report delinquent accounts to credit bureaus, and suspend driver's licenses, professional licenses, and recreational licenses including hunting and fishing permits.
Contempt of Court for Non-Payment
When administrative enforcement measures fail to secure payment, custodial parents can file a Complaint for Contempt in the Probate and Family Court asking the judge to hold the non-paying parent in contempt of the child support order. Courts schedule contempt hearings within 30-60 days of filing, and parents who fail to appear face a capias, which is a civil arrest warrant that may result in detention. Contempt findings can result in fines, mandatory payment plans, property seizure, and incarceration up to 90 days.
Massachusetts courts view child support obligations seriously and rarely accept excuses for non-payment when a parent has the ability to pay. Judges can attribute income to parents who are voluntarily unemployed or underemployed, meaning the court calculates support based on what the parent could earn through reasonable effort rather than their actual current income. Parents facing genuine financial hardship should file for modification of their support order rather than simply stopping payments, as arrears continue accumulating regardless of changed circumstances until a court modifies the order.
Modifying Child Support Orders in Massachusetts
Massachusetts allows modification of child support orders whenever there is an inconsistency between the current order amount and the amount that would result from applying the Child Support Guidelines to current circumstances. Unlike other family law modifications requiring a substantial change in circumstances, child support modifications follow a different standard based on guideline calculations. Courts generally consider a 25% change in either parent's income significant enough to warrant recalculation of support obligations.
To request a modification, the parent seeking the change must file a Complaint for Modification with the Probate and Family Court that issued the original order. Supporting documentation should include recent pay stubs, tax returns, evidence of job loss or income change, medical bills, or documentation of custody changes. Courts can only modify support prospectively from the date the complaint was served on the other parent. No modification applies retroactively to payments due before the filing date, making prompt filing essential when circumstances change.
Setting Up Your DOR Account and PIN
Every parent involved in a Massachusetts child support case receives a 10-digit Personal Identification Number (PIN) from DOR, which serves as the primary identifier for accessing account information and making payments. The PIN appears on billing statements, court orders, and other correspondence from DOR. Parents who cannot locate their PIN can request it online by providing their date of birth or by calling Customer Service at (800) 332-2733.
As of June 2025, all DOR child support accounts require access through MyMassGov, the Commonwealth's unified login system with multifactor authentication. To create a MyMassGov account, parents need their 10-digit PIN and a valid government-issued photo ID such as a driver's license, state ID card, or passport for identity verification. The system requires setting up multifactor authentication through text message, phone call, or authentication app to protect account security. Parents needing assistance with MyMassGov setup can call (800) 332-2733 and press option 7 for technical support.
Employer Responsibilities for Wage Withholding
Massachusetts employers who receive an Income Withholding Order must begin deductions within the first pay period occurring at least 14 days after receipt and forward withheld amounts to DOR within 7 business days of each pay date. Employers must continue withholding until DOR notifies them that the obligation has ended or the employee terminates employment. Upon termination, employers must notify DOR within 10 days and provide the employee's last known address and new employer information if available.
Employers cannot discharge, refuse to hire, or discipline any employee because of a child support withholding order. Violations of this anti-retaliation protection can result in civil liability to the affected employee. Employers processing multiple withholding orders for the same employee must follow priority rules established by federal and state law, with child support generally taking priority over other garnishments except federal tax levies. Large employers often set up Electronic Funds Transfer (EFT) arrangements with DOR for efficient processing of multiple withholding cases.
Child Support and Tax Considerations
Child support payments in Massachusetts are not tax-deductible for the paying parent and not taxable income for the receiving parent under federal and state tax law. This treatment differs from alimony, which followed different tax rules before 2019 and may have different treatment depending on when the divorce was finalized. Parents should not confuse child support with alimony when preparing tax returns, as misreporting can trigger IRS audits and penalties.
The tax refund intercept program allows DOR to collect past-due child support from both federal and state tax refunds. If a parent owes $150 or more in past-due support, DOR can intercept their Massachusetts state tax refund. For federal refunds, the threshold is $500 for cases not receiving public assistance and $150 for cases that have received public assistance. Parents expecting a tax refund who also owe child support arrears should anticipate that some or all of the refund may be applied to their child support debt.
Frequently Asked Questions
What is the fastest way to pay child support in Massachusetts?
Wage withholding provides the most reliable payment method because employers automatically deduct and forward payments to DOR within 7 business days of each pay period. For parents needing to make additional or catch-up payments, online payments through ma.smartchildsupport.com using credit card, debit card, Venmo, or PayPal typically post within 2-3 business days.
Can I pay child support directly to my child's other parent in Massachusetts?
No. Massachusetts requires all court-ordered child support payments to go through the Department of Revenue Child Support Enforcement Division. Payments made directly to the other parent do not receive official credit toward your support obligation, even if both parents agree to direct payments. Only payments processed through DOR count toward your legal obligation.
What happens if my employer does not withhold child support from my paycheck?
If your employer fails to set up wage withholding after receiving a DOR income withholding order, you must make payments directly to DOR through an alternative method until withholding begins. Contact DOR at (800) 332-2733 to report employer non-compliance. Employers who fail to withhold face penalties of $100 per violation plus liability for the uncollected support amount under MGL c. 119A.
How much of my paycheck can Massachusetts take for child support?
Massachusetts limits child support wage withholding to 50% of disposable earnings for parents currently supporting a spouse or other children, and 60% for those without additional dependents. If arrears exceed 12 weeks of payments, these limits increase to 55% and 65% respectively to accelerate collection of past-due amounts.
What is the penalty for late child support payments in Massachusetts?
DOR applies 0.5% interest and 0.5% penalty monthly on late payments exceeding $500 in arrears. A parent $10,000 behind accumulates $100 per month in additional charges. Additional enforcement can include driver's license suspension, professional license suspension, tax refund interception, bank account levy, and contempt of court proceedings with potential jail time up to 90 days.
How do I get my Massachusetts child support PIN number?
Your 10-digit PIN appears on DOR billing statements, court orders, and correspondence. If you cannot locate your PIN, submit a request online at mass.gov providing your date of birth, or call Customer Service at (800) 332-2733. You will need this PIN to set up your MyMassGov account, make payments, and access your case information.
Can I use Venmo or PayPal to pay child support in Massachusetts?
Yes. Massachusetts added Venmo, PayPal, Apple Pay, and Google Pay as payment options through the ma.smartchildsupport.com portal. These digital wallet payments process like credit card transactions with similar fees and 2-3 business day posting times. You must link your digital wallet through the official DOR portal rather than sending payments directly.
How do I change my child support payment amount in Massachusetts?
File a Complaint for Modification with the Probate and Family Court that issued your original order. Massachusetts allows modification whenever there is an inconsistency between your current order and what the Child Support Guidelines would calculate based on current income. Courts generally consider a 25% income change significant. Modifications only apply from the date of filing forward.
Where can I pay child support in cash in Massachusetts?
MoneyGram locations including Walmart, CVS, and Shaw's stores accept cash child support payments using Receive Code 14664. You need your DOR PIN to complete the transaction. Cash payments reach DOR within 3 business days. MoneyGram charges a fee of approximately $3.99 to $7.99 depending on the payment amount and location.
