Not filing does not mean the IRS forgets. They file a Substitute for Return under IRC Section 6020(b) using your W-2s and 1099s. Worst possible filing status, standard deduction only, zero credits. The result is always a higher tax bill than what you would owe on a properly filed return.
The IRS requires the last six years of unfiled returns to consider you compliant. File those six years and every collection alternative opens up. A tax lawyer can reconstruct returns, negotiate with the IRS on SFR assessments, and build a resolution strategy. Start the conversation today.
