Filing taxes isn’t mandatory for everyone, but understanding your personal requirements is crucial to avoid penalties and maximize your benefits.
Many people don’t realize that federal tax filing obligations depend primarily on your gross income and filing status, as defined by the IRS. Even if your income falls below the filing threshold, submitting a tax return might still be advantageous to claim potential refunds.
Here’s a comprehensive overview of who needs to file taxes in 2024, including key considerations and consequences of not filing.
Essential Highlights
- Filing federal taxes is not required for everyone.
- Your income level and tax filing status determine your filing obligation.
- Most states require a state tax return if you file federally.
- Filing voluntarily can help you claim refunds and tax credits.
- Failure to file when required may result in financial penalties.
Federal Tax Filing Requirements for 2024
The IRS bases filing requirements on your gross income, age, and filing status. There’s no minimum age for filing; it’s all about your income and status.
Seniors (65+): Eligible to use Form 1040-SR, designed specifically for seniors, which may offer additional tax advantages.
Married Filing Separately: If married and filing separately with income exceeding $5, you must file regardless of other factors.
Dependents: Filing rules vary based on age, income, and income type for dependents such as children or students.
Self-Employed: If your net earnings exceed $400, filing is mandatory even if your total income is below other filing thresholds.
IRS Direct File Pilot Program
In 2024, the IRS introduced a Direct File pilot allowing select taxpayers to file 2023 returns online directly with the IRS for free, available in certain states and income brackets.
Income Thresholds for Filing in 2024
The IRS updates income thresholds yearly. For example, single filers under 65 must file if gross income is $14,600 or more; married couples filing jointly under 65 must file if combined income reaches $29,200 or more.
Refer to IRS Publication 17 and 501 for detailed updates and future changes.

Professional Advice
Consult a tax professional if you’re uncertain about filing requirements, tax obligations, or potential penalties.
State Tax Filing Rules
Most U.S. states require a state tax return when you file federally. Additionally:
- If you earned income in multiple states, you might need to file returns in each.
- State-specific rules vary; tools like TurboTax can help clarify your obligations.
Why File Taxes If Not Required?
Even if your income is below filing thresholds, filing can be beneficial.
Claiming Refunds
You may be entitled to a refund if taxes were withheld from your paycheck or if you qualify for refundable credits.
Tax Credits
Filing allows you to claim credits such as the Earned Income Credit (EIC), Child Tax Credit, Saver’s Credit, and education-related credits that could increase your refund.
The EIC for 2024 offers up to $8,046 for filers with three or more children and $649 for single filers without children, depending on income and filing status.
Record Keeping
Keep tax returns for up to six years in case of IRS inquiries or audits.
Penalties for Not Filing When Required
If required to file and you don’t, penalties apply:
- Late Filing: 5% of unpaid taxes per month, up to 25% total.
- Failure to Pay: 0.5% of unpaid taxes per month.
- Minimum Penalty: After 60 days, minimum penalty equals 100% of unpaid taxes or a set dollar amount (e.g., $485 in recent years).
Important Update on Retirement Accounts
Under SECURE Act 2.0, required minimum distributions (RMDs) must begin by April 1 following the year you turn 73 (for those born after Jan 1, 1951), adjusting prior age requirements.
Special Filing Situations
- Self-employed individuals earning over $400.
- Those subject to excise taxes on retirement accounts, such as missed RMD penalties.
- Individuals owing Social Security or Medicare taxes on unreported tips.
Summary: Do You Need to File?
