In order to convict you of a tax crime, the IRS does not have to prove the exact amount you owe. The IRS has a general policy of not enforcing the filing of returns older than six years. The IRS can collect taxes, interest, and penalties for all of the taxes you have owed over the years. The IRS has programs in place to identify nonfilers. The filing of a return starts the audit and collection time limits. If you do owe taxes, you can probably work out an installment plan to pay off your debt. You may be able to negotiate a settlement with the IRS, depending on your ability to pay, that will significantly diminish your overall tax debt. The IRS may owe you money.
