Sole Proprietorships

Learn the requirements of operating your business as a sole proprietorship, including registering with MassTaxConnect and making estimated tax payments.

Overview

Sole proprietors who will be collecting Business/Trustee Taxes need to: 

  • Register with MassTaxConnect
  • Pay Massachusetts personal income tax on business profits
  • File Form 1, Massachusetts Resident Income Tax Return, or Form 1-NR/PY, Massachusetts Nonresident/Part-Year Resident Income Tax Return annually
  • File a Schedule C, Profit or Loss from Business or Profession, with the Form 1 or Form 1 NR/PY for each business owned, on or before the 15th day of the fourth month after the close of the business's taxable year.

Nonresidents can visit the Massachusetts nonresident regulation, 830 CMR 62.5A.1: Nonresident Income Tax for more information.

Keep in mind: A husband and wife running a business together are considered a partnership, not a sole proprietorship.

Making estimated payments

As a taxpayer, you must make quarterly estimated tax payments if the expected tax due on your taxable income not subject to withholding is more than $400. This is to ensure that you are meeting the statutory requirement that taxes due are paid periodically as income is received during the year. 

Generally, you need to pay at least 80% of your annual income tax liability before you file your return for the year through withholding or by making quarterly estimated tax payments on any income not subject to withholding. 

Farmers and fishermen generally need to pay at least two-thirds (66.67%), rather than 80%, of their annual income tax liability before the year's return is filed. You qualify as a farmer or fisherman for any taxable year if your gross income from farming or fishing is at least two-thirds (66.67%) of your annual gross income.

You must pay estimated tax if you are:

  • An individual and you expect to have a tax due of more than $400
  • Filing for a fiduciary, trust, or non-profit organization and you expect to have a tax due of more than $400.

Types of income you may not have had taxes withheld from:

  • Salaries and wages from employment not subject to Massachusetts withholding
  • Unemployment compensation (if you did not elect voluntary Massachusetts withholding)
  • Dividends and interest income
  • Gains from the sale or exchange of capital assets
  • Income from a trade, business, profession, partnership, or S corporation
  • Income from an estate or trust
  • Certain lottery or gambling winnings
  • Income from certain pensions or retirement savings plans
  • Rental income
  • Alimony.
