Essential June 2025 Tax Deadlines for Individuals: Key Due Dates, IRS Guidance, and Compliance Strategies

Master Your June 2025 Tax Compliance: Critical Due Dates for Individuals

Staying compliant with IRS requirements and due dates is a hallmark of good financial stewardship. As tax regulations grow increasingly complex, timely filing and accurate reporting are imperative for avoiding costly penalties and interest. June 2025 is packed with essential individual tax deadlines—ranging from IRA documentation and tip income reporting to estimated tax payments and special scenarios for expatriates and military personnel. This guide provides tax professionals, freelancers, and individuals with in-depth insights into these requirements, along with best practices for navigating deadlines and leveraging safe harbor rules.

June 2: Final Deadline for IRA Trustees – Form 5498

Form 5498 is a cornerstone document in the realm of retirement account administration. By June 2, 2025, all IRA trustees must issue Form 5498 to IRA owners, accurately reporting the fair market value (FMV) of accounts as of December 31, 2024. The FMV is central in calculating the Required Minimum Distribution (RMD) for account holders who will reach age 73 or older during 2025. Failure to distribute or report the FMV may result in IRS scrutiny and excise taxes. Ensure all custodians adhere to these deadlines to maintain regulatory compliance, and review FMV statements for accuracy, especially if handling inherited IRAs or complex asset mixes.

June 10: Mandatory Reporting of Tips – IRS Form 4070

Service industry professionals must pay close attention to tip reporting. Employees receiving more than $20 in tips during May must report the total to their employer using IRS Form 4070 by June 10. Accurate tip reporting not only fulfills tax obligations, but ensures proper calculation of FICA and income tax withholdings on your W-2. If regular wages do not cover these withholding amounts, the employer will reflect any uncollected FICA on box 8 of the W-2, creating an add-on liability due with your annual return. To mitigate tax surprises, track all gratuities daily and set aside estimated amounts for potential tax shortfalls.

June 16: Second Quarter 2025 Estimated Tax Payment

The IRS operates under a “pay-as-you-earn” model, which includes mechanisms such as payroll withholding for employees, pension withholding for retirees, and quarterly estimated tax payments for self-employed individuals, freelancers, investors, and others with untaxed income streams. June 16 is the deadline for the second estimated tax installment for the 2025 tax year.

Failing to prepay a safe harbor amount triggers an underpayment penalty. This penalty combines the federal short-term interest rate plus 3 percentage points, calculated quarterly. There are, however, two prominent ways to avoid penalties:

  • 90% Current-Year Exception: You will not incur a penalty if prepayments (estimated taxes, withholdings) are at least 90% of the total current-year tax liability.
  • 100/110% Prior-Year Exception: Alternatively, if payments equal 100% of the prior year’s tax liability (or 110% for higher-income taxpayers earning over $150,000 AGI or $75,000 for married filing separately), you are protected from penalty.
Example: If your 2025 tax due is $10,000 and you prepaid only $5,600, the current-year safe harbor (90% = $9,000) isn't met. But if your 2024 tax liability was $5,000, your $5,600 prepayment surpasses the 110% prior-year safe harbor ($5,500), and you will not be penalized.



Proactive quarterly payments are crucial for those earning project- or commission-based income, selling high-value assets, or receiving windfalls. Consult your tax advisor to confirm the correct safe harbor exceptions for your situation, and consider adjusting estimated payments following drastic changes in income.

Note: State-level estimated tax rules, de minimis thresholds, and due dates frequently differ from federal regulations. Engage with your CPA or tax specialist to ensure comprehensive compliance in all relevant jurisdictions.

June 16: Special Tax Deadlines for U.S. Citizens Abroad & Military in Combat Zones

U.S. citizens and resident aliens living and working abroad benefit from a June 16, 2025, due date for filing their 2024 tax return (Form 1040/1040-SR) and remitting any owed taxes. Should you require additional filing time, submit Form 4868 for an automatic four-month extension until October 15. However, this extension applies solely to filing, not payment; late payments accrue penalties and interest from the original deadline. Estimate and pay any anticipated tax owed alongside your extension to minimize fees.

Military personnel serving in combat zones or designated hazardous duty areas receive extra protection: tax deadlines are automatically postponed to 180 days after leaving the qualifying area (or after hospitalization due to service-related injuries). This extension period may further lengthen by the number of days remaining on prior IRS deadlines upon entering the zone. This benefit also applies to certain contingency operations such as those under Operation Enduring Freedom or similar missions. Stay aware of these provisions when handling financial matters during deployment and consider automatic payment plans or IRS installment agreements to avoid late-filing penalties.

Weekend, Holiday, and Disaster Area Adjustments

If a federal tax due date falls on a Saturday, Sunday, or designated legal holiday, the due date automatically extends to the next business day. In the event of federally recognized disasters, both IRS and state agencies may further extend tax deadlines for impacted regions.

Conclusion: Proactive Compliance is Key

June is a pivotal month for tax planning and compliance. Taxpayers should prioritize documentation, accurate reporting, and timely payments to take full advantage of available safe harbors and avoid unnecessary penalties. Whether dealing with estimated taxes or unique filing circumstances like foreign residence or military service, collaborating with an experienced tax advisor can help streamline processes and preserve financial health.
