“Do I have to pay income taxes on my personal injury settlement?”

No. If you receive a settlement for a personal injury case, the IRS deems that settlement as making up for a loss you sustained and not income.  So if your car is stolen, and your insurance company gives you a check for the value of the car, that money you get from insurance for the stolen car is not taxable because it making up for the loss you sustained, the money the insurance company gives you is not “income.”
