Maine rules for construction & trades
- State income tax (2026)
- Maine has a graduated state income tax for 2026: 5.8% to 9.15% (top rate starts at $1,000,000 for single filers). 2026 single-filer brackets are 5.8% under $27,400, 6.75% from $27,400 to $64,850, and 7.15% at $64,850 and above. A new 2% surcharge starts in 2026 on Maine taxable income over $1,000,000 (single; $1,500,000 joint or head of household), so the effective top marginal rate is 9.15%. The standard deduction is $15,700 (single) and the personal exemption is $5,300.
- State estimated tax
- Generally required if your Maine tax after withholding and credits is expected to be $1,000 or more and your prior-year tax liability was also $1,000 or more. Same dates as federal (April 15, June 15, Sept. 15, 2026, and Jan. 15, 2027). A special rule applies to 'unusual event income': if your income not subject to withholding beats the same quarter last year by $500,000 or more, you must pay 90% of the tax on that extra income that quarter, and the prior-year safe harbor does not cover it. Form 1040ES-ME.
- Maine employee vs. independent contractor standard
- One test decides employee status for workers' comp, unemployment insurance, and wage-and-hour law. A worker is an employee unless they meet all 5 required criteria (for example, they control how the work is done and run an independently established business) plus at least 3 of 7 more. Intentional misclassification can bring penalties of up to $10,000.
- Maine Paid Family and Medical Leave: self-employed opt-in
- Benefits began May 1, 2026. Self-employed people are not covered automatically but can opt in through the Maine Paid Leave portal. The premium is 0.5% of self-employment income for 2025-2027.
- State retirement program
- Maine Retirement Investment Trust (MERIT) is live. It is built around W-2 employers and does not cover 1099 contractors through the employer mandate; self-employed residents can enroll on their own.
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.
