Eligible nonprofits can only file form 990-N after the end of its tax year. The tax year is determined by your nonprofit’s fiscal period. So if your organization’s fiscal year is, October 1, 2020 through September 30, 2021, it must wait until October 1, 2021, to file. On the other hand, if your nonprofit is eligible to file form 990-N for tax year 2020 and uses a calendar year of say January through December, it must wait until January 1st, 2021, to file.
Eligible nonprofits must file by the 15th day of the 5th month after the close of their tax year.
Failure to File
It is important that your nonprofit organization take filing its form 990-N seriously because failure to file could mean revocation of your nonprofit’s tax-exempt status. If your tax-exempt status is ever revoked by the IRS, your nonprofit will no longer be eligible for federal tax exemption.
