A Flat 5% With Almost Nothing Deducted First
No standard deduction
Most states let you subtract a five-figure standard deduction before tax. Massachusetts does not have one. A single filer subtracts a $4,400 personal exemption, or $8,800 on a joint return, and pays 5% on the rest.
That is why the Massachusetts bill on $75,000 of profit, $3,265, is higher than in several states with a higher published rate. The 4% surtax on income above roughly $1.08 million does not concern most freelancers.
The health insurance mandate comes with a tax-return penalty
Massachusetts still enforces its own individual mandate. Adults must have health coverage that meets the state's minimum creditable coverage standard, and you report it on Schedule HC with your return. An employee is usually covered through work. A freelancer has to arrange it, typically through the Health Connector.
If you go without, the penalty for 2026 rises with income, from $26 a month to $211 a month for people above 400% of the federal poverty level. A full year uncovered at that level costs $2,532. A gap of three months or less is not penalised. The schedule is in the Department of Revenue's Technical Information Release 26-1.
Paid Family and Medical Leave is optional
Self-employed people can elect coverage under the state's PFML program. You register with the Department of Family and Medical Leave, pay contributions on your income, and become eligible for benefits once you have contributed for at least two of the last four quarters. The program's contribution rate for 2026 is 0.88% of eligible earnings. The state's page for self-employed people shows how it applies to you.
Quarterly payments
Massachusetts expects estimated payments when you will owe more than $400 for the year, a lower trigger than the federal $1,000. No Massachusetts city or town taxes income, and the 6.25% sales tax does not apply to professional services.
