According to The Chronicle of Philanthropy, 275,000 nonprofits have lost their tax-exempt status because they did not file legally required documents for three consecutive years.

Many of the groups that lost their exemptions are charities, and donors to those organizations cannot claim a charitable deduction for gifts to the groups after the IRS makes the list official.

Most of the organizations knocked off the charity rolls are believed to be defunct, the IRS said, but groups that are still operating may now apply to get their charity status back.

… Organizations that are affected by today’s action can ask the IRS to reinstate their tax-exempt status retroactively. Applying can cost as much as $850, but the fee will be reduced for small groups that can prove they had good reason not to comply with the paperwork rules.

A review of those organizations who have lost their tax exempt status contains a number of Jewish world organizations – however it can not be ascertained from the list if they are active or defunct.
