No, you generally cannot skip a year of filing taxes if you meet the IRS filing requirements (income thresholds, self-employment earnings, etc.), as it's a legal obligation that can lead to significant penalties and interest if you owe taxes, though you might not need to file if your income is below the standard deduction and you have no other filing triggers.

No, the IRS doesn't catch every instance of unreported income, but their advanced data-matching systems catch most discrepancies involving third-party reporting (like W-2s, 1099s for freelance/interest/dividends) through automated checks, leading to CP2000 notices and potential penalties if missed; however, cash income, crypto, or lifestyle mismatches can also trigger scrutiny, though it's less certain than reported income, and high-income non-filers are a current focus.
