From form 2210 instructions,
Federally declared disaster. Certain estimated tax payment deadlines for taxpayers who reside or have a business in a federally declared disaster area are postponed for a period during and after the disaster. During the processing of your tax return, the IRS automatically identifies taxpayers located in a covered disaster area (by county or parish) and applies the appropriate penalty relief. Don't file Form 2210 if your underpayment was due to a federally declared disaster. If you still owe a penalty after the automatic waiver is applied, the IRS will send you a bill.
