The Single Sales Factor may apply to the following types of companies that have multi-state tax filings:
- Manufacturing companies
- Qualifying defense contractors
- Qualifying financial service providers
Terms and Conditions
- When the Single Sales Factor applies, the net income subject to Massachusetts tax is determined by multiplying the overall net income by the single sales factor apportionment factor.
- The Single Sales Factor apportionment is the ratio of Massachusetts sales to overall sales.
- The Single Sales Factor apportionment is considered advantageous in Massachusetts when compared to many states that use a Three-Factor Apportionment, which weighs not only state sales, but also property and payroll as a percent of overall sales, property, and payroll.
- The Single Sales Factor is also advantageous for companies with significant property and payroll. Since the Single Sales Factor apportionment only weighs the sales, companies are not penalized for investing or hiring.
How to Apply
