Massachusetts employers pay their share of federal payroll taxes plus state-specific unemployment and paid leave contributions. Understanding these costs helps you budget accurately and stay compliant.

Federal payroll taxes include the employer portion of Social Security and Medicare. Social Security tax is 6.2% of wages up to the annual wage base. Medicare is 1.45% on all wages with no cap. Combined, that’s 7.65% on top of every paycheck you issue.

Federal Unemployment Tax applies at 6% on the first $7,000 of wages per employee annually. Employers who pay state unemployment taxes on time receive a 5.4% credit, reducing the effective FUTA rate to 0.6%. Pay late and you lose part or all of that credit.

Massachusetts requires employers to pay state unemployment insurance on the first $15,000 of each employee’s wages. New employers typically start with a standard rate around 2.42%, but your rate changes over time based on your claims experience. Rates can range from under 1% to over 18% depending on how many former employees have filed unemployment claims against your account. A history of layoffs or high turnover drives your rate up.

The state’s Paid Family and Medical Leave program adds another layer. Employers with 25 or more covered employees must pay 0.18% of wages toward PFML. Smaller employers can choose to cover this or pass it entirely to employees through withholding. There’s also an employee contribution portion that you collect from wages regardless of your size.

For most employers, figure roughly 10% to 12% on top of gross wages for all employer-paid payroll taxes. The exact amount depends on your unemployment experience rating and whether you’re above the PFML employer threshold. Higher-wage employees cost less as a percentage once they exceed the Social Security wage base and state unemployment caps.

You need to register with the Massachusetts Department of Revenue for withholding, the Department of Unemployment Assistance for unemployment insurance, and the PFML program separately. Each has its own filing schedule and payment requirements. Missing deadlines means penalties and interest that add up quickly.

Tracking these obligations manually gets complicated, especially when rates change or you add employees. Full-service payroll handles tax calculations, deposits, and filings so you’re not juggling multiple deadlines. Combined with a bookkeeper for small business, you get accurate labor cost tracking and clean financials without the compliance headaches.
