The Internal Revenue Service (IRS) is reminding taxpayers about significant financial consequences, including penalties and accumulating interest, for failing to file or pay taxes by the established deadlines. These charges can substantially increase the amount owed, and the agency highlights a "60-day rule" which may affect the start date of interest on certain penalties. Taxpayers facing difficulties in paying their full tax liability are advised of options such as payment plans and penalty abatement requests.
Understanding IRS Penalties and Interest
The IRS imposes penalties and interest on taxpayers who do not meet their tax obligations. These can include:
Failure-to-File Penalty: Charged when a tax return is filed after the due date or extended due date, unless there is a reasonable cause for the delay.
Failure-to-Pay Penalty: Applied if a taxpayer files a return but does not pay the full amount owed.
Interest: Accrues on unpaid taxes and penalties from the due date until the balance is paid in full. This interest compounds daily and can increase the total amount owed.
The IRS charges interest on penalties, which adds to the total debt until it is fully settled.
The "60-Day Rule" and Penalty Interest
The start date for interest charges on penalties can vary, with a specific "60-day rule" noted in relation to certain penalty types. While the exact parameters of this rule are not fully detailed in the provided materials, it is presented as a key point for taxpayers to be aware of concerning when interest on penalties begins to accrue.

Circumstances for Penalty Relief and Abatement
Taxpayers may be eligible for penalty relief in certain situations.
Reasonable Cause: The IRS may waive penalties if a taxpayer can demonstrate "reasonable cause" for failing to file or pay on time. This could include unforeseen events or circumstances beyond the taxpayer's control.
First-Time Penalty Abatement: Individuals who have a history of filing and paying taxes on time for the past three years might qualify for a one-time penalty waiver.
Error in Assessment: If a taxpayer believes a penalty or interest has been charged in error, they have the option to request an abatement.
Refunds do not incur penalties for late filing.
Inflation Adjustments and Tax Preparer Penalties
The IRS adjusts its penalties annually for inflation. This means penalty amounts can increase over time.

Inflation-Adjusted Penalties: For 2025 and 2026, the IRS has announced inflation-adjusted penalties. Specific figures for these adjustments are available through IRS publications.
Tax Preparer Penalties: The IRS also enforces penalties on tax professionals who fail to meet their responsibilities, such as not furnishing copies of returns to clients or lacking diligence in determining credit eligibility. These penalties can be significant, for example, $650 per failure for certain actions.
The IRS emphasizes that penalties are designed to encourage compliance with tax laws.
Payment Options and Seeking Assistance
Taxpayers unable to pay their full tax liability by the deadline have several options:
Payment Plans: The IRS offers payment plans for those who cannot pay the full amount of taxes or penalties on time.
Pay What You Can: Even if a full payment isn't possible, submitting a tax return on time can help avoid the harshest penalties. Various payment methods are available, including IRS Direct Pay and electronic payments.
Professional Assistance: For those unsure about their tax situation, estimating amounts owed, filing returns, or handling IRS notices, seeking assistance from a qualified tax professional is recommended.
Submitting a tax return on time, even if payment cannot be made in full, can help avoid the most severe penalties.
Expert Analysis
"The IRS has a structured approach to collecting taxes, which includes penalties and interest to ensure timely compliance. Taxpayers should understand that interest compounds daily on unpaid balances, significantly increasing the debt over time. While penalty relief is possible under specific circumstances like reasonable cause, it’s crucial to file returns promptly, even if payment is delayed. The '60-day rule' mentioned likely pertains to the notification period or the commencement of interest on specific penalties, underscoring the importance of timely response to IRS notices." - An unnamed tax professional with over 15 years of experience.

Taxpayers should prioritize filing their returns by the deadline and making payments as they earn to align with the U.S. 'pay as you go' tax system.
Conclusion and Next Steps
The IRS's recent advisories serve as a clear warning regarding the financial repercussions of late tax filings and payments. Penalties, such as the failure-to-file and failure-to-pay charges, are compounded by interest that accrues daily, increasing the total debt. The mention of a specific "60-day rule" related to interest on penalties suggests a critical timeframe for taxpayer awareness and action.
While the IRS offers avenues for penalty relief based on reasonable cause or first-time abatement, and provides payment plan options, proactive compliance remains the most effective strategy to avoid these escalating financial burdens. Taxpayers are encouraged to be aware of inflation adjustments to penalties and the specific obligations placed upon tax professionals.
