What Is the Business Income Tax in Massachusetts?

What kind of tax will you owe on Massachusetts business income?

Updated by , J.D.

Most states tax at least some types of business income derived from the state. As a rule, the details of how income from a specific business is taxed depend in part on the business's legal form. In most states, corporations are subject to a corporate income tax, while income from pass-through entities such as S corporations, limited liability companies (LLCs), partnerships, and sole proprietorships is subject to a state's tax on personal income. Tax rates for both corporate income and personal income vary widely among states. Corporate rates, which most often are flat regardless of the amount of income, generally range from roughly 4% to 10%. Personal rates, which generally vary depending on the amount of income, can range from 0% (for small amounts of taxable income) to around 9% or more in some states.

Currently, six states—Nevada, Ohio, South Dakota, Texas, Washington, and Wyoming—do not have a corporate income tax. However, four of those states—Nevada, Ohio, Texas, and Washington—do have some form of gross receipts tax on corporations. Moreover, five of those states—Nevada, South Dakota, Texas, Washington, and Wyoming—as well as Alaska, Florida, and Tennessee currently have no personal income tax. Individuals in New Hampshire are only taxed on interest and dividend income.

Apart from taxing business income through a corporate income tax or a personal income tax, many states impose a separate tax on at least some businesses, sometimes called a "franchise tax" or "privilege tax." This tax is frequently justified as a tax simply for the privilege of doing business in the state. As with state taxes on business income, the specifics of a state's franchise tax often depend in part on the legal form of the business. Franchise taxes are generally either a flat fee or an amount based on a business's net worth.

How Business Income Tax in Massachusetts Works

Massachusetts has a corporate excise tax which, generally speaking, is based both on income and net worth. The tax applies to traditional corporations and, at least to some extent, to S corporations. There is no entity-level tax that applies to other forms of business, such as LLCs or partnerships. But if income from your business passes through to you personally, then regardless of the legal form of your business, that income will be subject to taxation on your personal state income tax return.

For traditional corporations (C corporations), the corporate excise tax generally is the sum of two amounts:

  • a tax of $2.60 per $1,000 of the greater of either taxable Massachusetts tangible personal property or taxable net worth, and
  • an 8.00% tax on income attributable to Massachusetts.

There is a minimum excise tax for corporations of $456.

The amount of corporate excise tax that an S corporation generally is required to pay depends in part on the corporation's gross receipts. More specifically:

  • If an S corporation's gross receipts are less than $6 million, the corporation owes a tax of $2.60 per $1,000 of either taxable Massachusetts tangible personal property or taxable net worth.
  • If an S corporation's gross receipts are $6 million but less than $9 million, the corporation not only owes the latter amount based on property or net worth but also owes a tax of 2% on its gross receipts.
  • If an S corporation's gross receipts are $9 million or more, the corporation not only owes the foregoing amount based on property or net worth but also owes a tax of 3% on its gross receipts.

In addition, S corporations, like traditional corporations, are required to pay a minimum excise tax of $456.

Determining which of the two values, tangible personal property or net worth, a traditional corporation or S corporation needs to pay tax on requires working through a special Massachusetts tax schedule (Form 355, Schedule B for traditional corporations and Form 355S, Schedule B for S corporations).

For the sake of comparison, note that Massachusetts taxes most personal income at a flat rate of 5%.

Let's briefly look at additional details for five of the most common forms of Massachusetts business: corporations (C corporations), S corporations, LLCs, partnerships, and sole proprietorships.

Corporations

Massachusetts corporations are subject to Massachusetts's corporate excise tax, which is based on both a measure of net worth and on income.

S Corporations

An S corporation is created by first forming a traditional corporation and then filing a special form with the IRS to elect S status. Unlike a traditional corporation, an S corporation generally is not subject to separate federal income tax. Rather, as far as federal income tax is concerned, taxable income from an S corporation passes through to the individual shareholders, and each shareholder pays federal tax on their share of that income on their individual federal tax return. In other words, at least with respect to federal taxation, S corporations are pass-through entities. (Note that a shareholder's share of the S corporation's income need not actually be distributed to the shareholder in order for the shareholder to owe tax on that amount.)

Massachusetts is unusual in that it requires S corporations to pay corporate excise tax on either taxable tangible personal property or on net worth. In addition, S corporations with at least $6 million, but less than $9 million, in gross receipts are required to pay a tax on those receipts at a rate of 2%, and S corporations with $9 million or more in gross receipts are required to pay a tax on those receipts at a rate of 3%. Moreover, apart from the latter, entity-level taxes, each individual shareholder must pay state tax on their share of the corporation's income.

Limited Liability Companies (LLCs)

Standard Massachusetts LLCs are pass-through entities at both the federal and state levels. They are not required to pay income tax to the federal government, and they are not subject to Massachusetts's corporate excise tax. Instead, income from the business is distributed to the LLC members, and each individual member is subject to federal and state taxes on their share of the company's income.

While by default LLCs are classified for tax purposes as partnerships (or, for single-member LLCs, disregarded entities), it is possible to elect to have your LLC classified as a corporation. In that case, the LLC would be subject to Massachusetts's corporation excise tax.

Partnerships

Massachusetts partnerships are pass-through entities at both the federal and state levels. They are not required to pay income tax to the federal government, and they are not subject to Massachusetts's corporate excise tax. Instead, income from partnerships is distributed to the individual partners, and each individual partner is subject to federal and state taxes on their share of the partnership's income.

Sole Proprietorships

Income from your business will be distributed to you as the sole proprietor, and you will pay tax to the state on that income.

Note on Multistate Businesses and Nexus

Our primary focus here is on businesses operating solely in Massachusetts. However, if you're doing business in several states, your business might be considered to have nexus with those states and, therefore, might be obligated to pay taxes in those states. Also, if your business was formed or is located in another state but generates income in Massachusetts, it might be subject to Massachusetts taxes. The rules for taxation of multistate businesses, including what constitutes nexus with a state for the purpose of various taxes, are complicated. If you run such a business, you should consult with a tax professional.
