In this NOAA satellite handout image, shows Hurricane Florence it just makes landfall off the coast of the U.S. in the Atlantic Ocean on September 13, 2018. Coastal cities in North Carolina, South Carolina and Virginia are under evacuation orders as the Category 2 hurricane approaches the United States.
The IRS will grant some tax relief to residents who are reeling from Hurricane Florence.
The storm, which weakened to a tropical depression on Sunday, poured up to 40 inches of rain on North Carolina since Thursday.
Taxpayers affected by the storm will have additional time to file their quarterly estimated income taxes, which would have been due on Sept. 17. They will now have until Jan. 31, 2019 to file and pay the applicable levies for that period.

Further, if you had a valid extension to file your 2017 taxes by Oct. 15, the IRS will grant you additional time to file.
For now the postponement is available to residents in areas that are designated by the Federal Emergency Management Agency as qualifying for individual assistance.

Here are other tax-planning implications for households affected.
Casualty loss deduction
Be aware that the Tax Cuts and Jobs Act, the tax overhaul that went into effect this year, has changed the way you can claim personal casualty and theft losses.
Prior to the change, you were able to claim an itemized deduction for property losses that aren't reimbursed by insurance and that stem from natural disasters, fires and other events. The total of these losses need to exceed 10 percent of your adjusted gross income.
In 2016, the most recent year available, 154,274 tax returns claimed a casualty or theft loss deduction, according to data from the IRS.
Now, you may claim casualty losses on your taxes only in the event of a federally declared disaster. You can either claim them during year they occurred — 2018 — or in an amended return for the prior year.
Your loss deduction is still subject to the 10 percent of AGI threshold.
This change is in effect from 2018 through the end of 2025.
"If this were a storm over your house in New Jersey, you don't have this provision; where those affected by Florence in North Carolina likely will," said Craig Richards, a CPA and director of tax services at Fiduciary Trust Company International.
Limits on losses 
The Trent River (background) overflows its banks and floods a neighborhood during Hurricane Florence September 13, 2018 in River Bend, North Carolina.
Bear in mind that in order to claim the casualty or theft loss, you must be claiming itemized deductions.
The new tax law roughly doubled the standard deduction to $12,000 for individuals and $24,000 for married couples filing jointly, so fewer people are expected to itemize in 2018.
You should also be aware that how much you can claim as a loss will be reduced based on the insurance payout you receive for your damages.
If your losses are large enough that your deductions for the year exceed your income, you may have a net operating loss or NOL.
Individuals — not just businesses — may have an NOL from casualty and thefts.
You can use your net operating loss to reduce your tax in a previous year, which may result in a refund, according to Richards of Fiduciary Trust Company International.
Alternatively, you can use the loss to lower taxes in the future.
