Accounting software giant Wolters Kluwer CCH software was hacked on May 6, resulting in the vendor’s cloud-based CCH bookkeeping and accounting software going offline. As a result, CCH users couldn’t handle required tasks on behalf of their customers, including submitting electronic tax filings to the IRS. The U.S. Internal Revenue Service has given you a 7-day extension to submit several different types of filings that are coming due. The extension was granted because the accounting software giant was hacked.”]
