This is actually a somewhat complex question. In a personal injury claim, there are typically several different kinds of damages involved, and some of them are taxable and some are not. Some types of damages that aren’t typically taxable include
Your medical bills, assuming deductions weren’t taken previously
Emotional distress / Pain and suffering
Damages directly related to your injuries,
Loss/damage of personal property
While some of the damages that are common, but are taxable might include:
Lost wages, as they would have been taxed anyway
Punitive damages, if applicable
The specifics of your case can vary considerably, and these are just general guidelines. An experienced Semi-Truck Accident Attorney or your accountant will be better able to help you go over the details of your case to consider which parts of your compensation need to be considered with your taxes.
