View filing requirements for Form 1099

Learn more about filing your annual report of interest, dividends, and other taxable income.



You need to file an annual report of interest, dividends, and other income taxable under G.L. c. 62 if you were issued any of the following:

  • Form 1099-INT
  • Form 1099-Div
  • Form 1099-MISC
  • Any other forms in the 1099 series 

The income must be reported on the same basis that is required by the federal government.

We don't publish specifications for 1099 Reports. Generally, Form 1099 Reports, including dollar thresholds and corrected returns, follow federal guidelines in the IRS Publication 1220. We accept 1099 Reports and files created using those published specifications with some changes explained below.

Modifications to the Form 1099 specifications in IRS Publication 1220 are to be made for municipal bond interest as explained below.

Interest from bonds:
Use the 1099-INT format to record earnings on each state or local bond. Report the income as if it were taxable for federal purposes. You need to submit a return for each bond on which interest is paid.

Report payment amounts in positions 67-78 of the payee "B" record. Right-justify and zero-fill.

Interest from mutual funds:
Use the 1099-INT format to record earnings from:

  • Mutual funds
  • Money market funds, and
  • Unit investment trusts

Report the income as if it were taxable for federal purposes.

Use positions 44-46 of the "A" record to report the percentage of mutual fund portfolio income distribution attributable to bonds issued by Massachusetts, Puerto Rico, Guam and the Virgin Islands, rounded to the nearest whole number - e.g., 25.4% would be reported as 025 and 25.5% would be reported as 026. Report payment amounts in positions 67-78 of the payee "B" record. Right-justify and zero-fill.


You must submit 1099 Reports electronically when reporting 50 or more. Magnetic media such as reel tapes, track cartridges and/or CD-ROM are not allowed.
