Short-term capital gains are taxed at 8.5%, and long-term gains on collectibles at 12% (after a 50% deduction).
State estimated tax: Residents and nonresidents must pay estimated tax if they expect to owe more than $400 on income not subject to withholding. The 4% surtax must be included. Same dates as federal (April 15, June 15, Sept. 15, 2026, and Jan. 15, 2027). Form Form 1-ES.
Independent Contractor Law ABC test (M.G.L. c. 149, § 148B): Anyone performing services is an employee for wage-and-hour purposes unless the business proves all three parts: the worker is free from control, the work is outside the business's usual course, and the worker runs an independently established business of the same kind. Misclassification can bring criminal and civil penalties.
Attorney General settlement with Uber and Lyft (2024): Rideshare drivers must earn at least $32.50 per hour of engaged time (en route to and carrying riders), not counting tips.

Federal rules for 2026

W-2 or 1099 changes everything

On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.

Tools and equipment

Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.

Overtime deduction for W-2 workers

Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
