FAQ — TAX PREPARATION IN BOSTON TAX ADVISOR

I'm a self-employed consultant based in the Seaport District, often utilizing co-working spaces. Can I deduct these co-working fees, and are there any specific Massachusetts rules for home office deductions if I also work from my condo in the North End?

Yes, co-working space fees are generally deductible as ordinary and necessary business expenses under IRS Section 162. For home office deductions, Massachusetts largely follows federal guidelines. However, if you’re also claiming a home office deduction for your North End condo, ensure the space is used *exclusively and regularly* for business to avoid issues, especially if you also use the co-working space, as the IRS scrutinizes multiple business locations. Document all expenses meticulously.

What are the key state tax implications for a small tech startup in Kendall Square, Cambridge, specifically regarding the Massachusetts corporate excise tax and potential R&D credits, and how do these interact with federal filings?

Massachusetts imposes a corporate excise tax based on either net income (8.00% for tax years ending on or after January 1, 2024) or tangible property/net worth. Startups in Kendall Square should aggressively pursue the Massachusetts research and development (R&D) credit, which is 10% of the qualified research expenses exceeding 16% of the corporation’s Massachusetts gross receipts, or 5% of the first $250,000 of qualified research expenses. These state credits often require careful federal Form 6765 preparation to maximize benefits.

I own a multi-family property in Dorchester that I rent out. Beyond federal depreciation, are there any Massachusetts-specific property tax deductions or credits I should be aware of, and how does the Boston residential exemption impact my tax liability?

While Massachusetts doesn’t offer state-specific depreciation deductions beyond federal guidelines, you can deduct ordinary and necessary expenses related to your Dorchester rental property. The Boston residential exemption (up to $3,909.11 for FY2024) can significantly reduce your *personal* property tax burden on your primary residence, but it does *not* directly apply to investment properties. However, understanding this exemption is crucial for overall tax planning as a Boston property owner.

As a gig economy worker driving for a food delivery service like DoorDash throughout Boston, what is the Massachusetts sales tax implication on my services, and what mileage deduction rate should I use for my vehicle expenses?

Massachusetts generally does not impose sales tax on delivery services themselves, as they are considered services rather than tangible personal property. For mileage, you should use the federal standard mileage rate (e.g., 67 cents per mile for business use in 2024) for your vehicle expenses, as Massachusetts largely conforms to federal rules for this deduction. Keep meticulous records of all business miles driven throughout Boston and surrounding towns.

My small business in the Financial District recently received a grant from a Boston-based economic development program. Is this grant taxable at the state and federal level, and does it impact my Massachusetts Small Business Tax Credit eligibility?

Generally, most grants, unless specifically designated as tax-exempt (which is rare for business grants), are considered taxable income at both the federal and Massachusetts state levels. Receiving a grant itself doesn’t directly impact your eligibility for the Massachusetts Small Business Tax Credit, which is generally tied to employee health insurance contributions. However, the grant income will increase your gross receipts, which could indirectly affect other tax calculations or thresholds.

I'm a freelancer living in Somerville but working for a client located in New York. Do I need to worry about New York state income tax, or only Massachusetts income tax, and what is the Massachusetts tax rate for pass-through income for sole proprietors?

As a Massachusetts resident, you are generally taxed on all your income, regardless of where it’s earned. While you may have a *filing requirement* in New York if your income exceeds their threshold, you’d claim a credit for taxes paid to New York on your Massachusetts return to avoid double taxation. For sole proprietors, pass-through income is subject to the Massachusetts personal income tax rate, which is 5% for most types of income.
