Whether or not you are required to file a federal income tax return this year will depend on how much you earned (gross income) -- and the source of that income -- as well as your filing status and your age. Your gross income includes all the income you receive that is not exempt from tax, not counting your Social Security benefits, unless you are married and filing separately.
Whether you're counting on a fat tax refund or dreading tax filing because you know you'll owe the government money, filing taxes shouldn't be expensive. There are ways to get affordable (or even free) tax filing software and help to keep more of your refund or lessen the financial sting of paying off your tax bill.
Unfortunately, natural disasters, and losses from them, occur each year and will continue to impact people's lives, causing personal and financial loss, and in some cases, even severe financial and economic loss. The income tax rules may provide for a small silver lining if the right circumstances apply.
