Extension Process for Corporate Excise Taxpayers

For S corporations that are not included in a combined group, any amount
due must be paid either electronically or by using the voucher below before
the 15th day of the third month after the close of the taxable year, calendar
or fiscal. For S corporations that are calendar year filers the due date is
March 15, 2023.

The extension process is now automated so that all corporate excise
taxpayers are given an extension of time to file their tax returns if certain
payment requirements are met. Corporate excise taxpayers must have
paid the greater of (1) 50% of the total amount of tax ultimately due or
(2) the minimum corporate excise by the original due date for filing the
return. Taxpayers meeting the payment requirements will be given a seven-month extension in the case of corporate excise taxpayers filing combined reports and a six-month extension in the case of other corporate
excise taxpayers. However, taxpayers filing unrelated business income
tax returns will be given an eight-month extension. See TIR 15-15 for
more information.
Note: For corporate excise returns due on or after January 1, 2018, the
return due date for business corporations and S corporations included in
a combined group is now four months from the close of the corporation’s
or the principal reporting corporation’s tax year. See TIR 17-5; see also
Proposed Regulation 830 CMR 62C.11.1.

When Should the Payment with Form 355-7004
Be Submitted?

If at least 50% of the tax due or the minimum tax (whichever is greater)
is not paid by the return due date, the extension is null and void. If filing
Form 355U, payments may be allocated to subsidiaries when Schedule
CG is filed.

Will Interest and Penalties Be Due?
An extension of time to file a corporation tax return does not extend the
due date for payment of the tax. Interest will be charged on any tax not
paid on or before the original due date. Any tax not paid within the extended period is subject to a penalty of 1% per month, up to a maximum
of 25%, from the extended due date. If the extension is invalidated for
failure to meet the payment requirements then penalties and interest for
a late return and late payment will be assessed from the original due date
of the return.

corporations included in a combined group, any amount due must be
