As of Monday morning, the IRS’ call centers are down. This is probably a temporary situation. From the IRS:
In response to the national emergency and to protect our employees, America’s taxpayers, communities and our partners, the IRS has temporarily closed all Taxpayer Assistance Centers and discontinued face-to-face service throughout the country until further notice. The IRS is continuing to process tax returns, issue refunds and help taxpayers to the greatest extent possible. Click here for more info on taxpayer assistance center closures.
