Schedule for estimated tax payments
All corporations that reasonably estimate their corporate excise to be in excess of $1,000 for the taxable year are required to make estimated tax payments to Massachusetts.
Estimated taxes must either be:
- Paid in full on or before the 15th day of the third month of the corporation's taxable year or
- Paid in four installments according to the schedule below.
Corporate estimated tax installments are due as follows:
| Installment | % of Estimated Tax Due | Due Date from Start of Taxable Year |
|---|---|---|
| 1st | 40% | 15th day of 3rd month |
| 2nd | 25% | 15th day of 6th month |
| 3rd | 25% | 15th day of 9th month |
| 4th | 10% | 15th day of 12th month |
Note: New corporations in their first full taxable year with less than 10 employees have different estimated payment percentages: 30%, 25%, 25% and 20%.
Many corporations are required to pay electronically via MassTaxConnect. It is recommended that all corporations use electronic payment. See TIR 16-9.
Corporations not required to pay electronically may use Form 355-ES.
