File a Tax Return: Why This Matters:

The IRS sets minimum income levels to reduce paperwork for low earners. However, filing is mandatory if you meet these thresholds because:

• Tax Compliance: The government tracks income to prevent evasion.
• Social Programs: Income data determines Medicaid, SNAP, or housing assistance eligibility.
• Self-Employment: Even $400 in freelance income triggers filing to pay Social Security/Medicare taxes.

Example: A 20-year-old earning 15,000(Single status)∗∗must file∗∗, while someone earning 15,000 (Single status)∗∗must file∗∗, while someone earning 14,000 may skip it—unless they qualify for refundable credits.

Yes, you can—and sometimes should—file even with $0 income. Key reasons:

• Refundable Credits: Claim the Earned Income Tax Credit (up to 7,430 in 2025) or the American Opportunity Credit (7,430 in 2025) or the American Opportunity Credit (1,502 max) if eligible, even if you owe nothing.

• Documentation: Future loans or benefits (e.g., Social Security, Medicaid) may require tax transcripts to prove financial history.

2. What happens if I don’t file and owe nothing?

While no penalty applies, you risk:

• Losing Refunds: The IRS keeps unclaimed refunds after 3 years.
• Missed Stimulus Checks: Some state rebates (e.g., California’s Middle-Class Refund) require a filed return.
