FAQ — TAX PREPARATION IN BOSTON

I own a startup in the Seaport District. What specific Massachusetts tax credits or deductions should I be aware of that could significantly benefit my early-stage company?

Boston-based startups, especially in tech and biotech, should explore the Massachusetts Research and Development (R&D) Tax Credit, which mirrors the federal credit but has its own state-specific calculation (M.G.L. c. 63, § 31A). Additionally, consider the Economic Development Incentive Program (EDIP) for potential tax credits if your growth generates significant new jobs, and be aware of the Angel Investor Tax Credit (M.G.L. c. 62, § 6M) if you’ve secured local seed funding.

As a self-employed freelance designer living in the North End, what are the key Massachusetts estimated tax payment requirements and deadlines I need to follow to avoid penalties?

For self-employed individuals in Boston, Massachusetts generally requires estimated tax payments if you expect to owe more than $400 in state income tax. The payments are due quarterly: April 15, June 15, September 15, and January 15 of the following year. Failure to pay at least 80% of your current year’s tax liability through withholding or estimated payments can result in penalties, calculated using Form M-2210.

I'm a real estate investor with several rental properties in Dorchester. What are the specific Massachusetts property tax implications and potential deductions for residential landlords, beyond federal guidelines?

While property taxes are locally assessed by the City of Boston, these payments are deductible on your federal Schedule E. For Massachusetts state tax, you can deduct ordinary and necessary expenses related to your rental properties, including mortgage interest, insurance, repairs, and property management fees. However, Massachusetts does not have a separate state-level property tax deduction beyond what’s allowed federally for rental income.

My small business operates a boutique in Beacon Hill. Does the City of Boston levy any specific municipal taxes or require local business licenses beyond the state's corporate excise tax?

Yes, while Massachusetts imposes a corporate excise tax (a combination of an income measure and a non-income measure), the City of Boston itself doesn’t levy a separate municipal income or ‘business privilege’ tax on top of this. However, most businesses in Boston, including boutiques, are required to obtain specific local licenses and permits from the City’s Inspectional Services Department (ISD) and potentially other city agencies, depending on your specific operations, before opening.

I'm a Massachusetts General Hospital (MGH) employee with significant medical expenses not covered by insurance. Can I deduct these on my Massachusetts state tax return, and are there any differences from federal rules?

For Massachusetts state tax purposes (Form 1, Schedule A), you can deduct medical expenses that exceed 10% of your adjusted gross income (AGI), similar to federal rules for those under 65, but MassHealth allows a 7.5% AGI threshold for those 65 or older. This includes unreimbursed doctor visits, prescriptions, and certain medical equipment. It’s crucial to itemize deductions on both federal and state returns to claim this benefit.

I recently bought my first home in Jamaica Plain. Are there any Massachusetts-specific tax credits or deductions for first-time homebuyers beyond the federal mortgage interest and property tax deductions?

Massachusetts offers a ‘First-Time Homebuyer Savings Account’ (FTHBSA) deduction, allowing residents to deduct contributions (up to $1,000 for individuals, $2,000 for joint filers) to a special savings account designed to save for a down payment. While not a direct credit on the purchase itself, this pre-tax savings can reduce your taxable income. The federal mortgage interest and property tax deductions remain key benefits on your federal Schedule A.
