Upcoming Important Tax Deadlines

October 15 extended due date for federal individual tax returns.

Late-filing penalty rules and compliance.

Ongoing interest rates on unpaid tax balances.

If you filed a formal request for an extension to file your individual tax return, that official extension expires on October 15. Failing to file before this extension period runs out can result in severe late-filing penalties.

Upcoming Tax Deadlines Guide

There are no additional extensions available (except in presidentially designated disaster areas), so if you do not have all of the information needed to complete your return by October 15, please call this office immediately so we can explore your filing options.

If you are waiting for a Schedule K-1 from a partnership, S-corporation, or fiduciary return, the extended deadline for those entity returns is September 15 (September 30 for fiduciary returns). You should make immediate inquiries if you have not yet received this information from your advisors.

Late-filed individual federal returns are subject to an IRS penalty of $5% of the tax due for each month (or part of a month) for which a return is not filed, up to a maximum of $25% of the total tax due. If you are required to file a state return and fail to do so, the state will also charge a late-filing penalty. The filing extension deadline for individual returns is also October 15 for most states.

In addition, interest continues to accrue on any unpaid balance due, currently indexed at the rate of $3% per year. This rate is subject to standard IRS quarterly adjustments.

If this office is currently waiting for missing information to finalize your returns, we must receive that data at least one week prior to the October 15 due date. Please contact our office immediately if you anticipate complications in gathering these records.

Additional October 15 Deadlines

In addition to being the final deadline to file your individual returns on extension in a timely manner, October 15 is also the deadline for the following actions:

FBAR Filings: Taxpayers with foreign financial accounts exceeding an aggregate value of 10,000$ at any time during the tax year must file FinCEN Form 114, Report of Foreign Bank and Financial Accounts (FBAR) electronically with the Treasury Department. While the original due date is April 15, taxpayers receive an automatic extension to October 15.

SEP-IRAs: October 15 is the absolute deadline for a self-employed individual to set up and contribute to a SEP-IRA for the previous tax year. Note that the traditional and Roth IRA contribution deadline is April 15, with no further extensions available.

Special Note: Disaster Victims: If you reside in a presidentially declared disaster area, the IRS and state tax agencies provide additional time to file various returns and make outstanding tax payments.

Please contact our office for specific details regarding the extended due dates of other entity filings and disaster-relief provisions.


Retrospective SBA Audit & Compliance Guidelines

While historic PPP loans provided critical relief during major economic cycles, the administrative workload did not end with receiving forgiveness. The SBA retains the statutory authority to audit any PPP loan of any size. To protect your business from retrospective audits, understanding your document retention requirements is essential.

💡 Potential Automatic Forgiveness & Audit Scope

Standard regulatory data shows that more than $86% of all PPP loans under 150,000$ received simplified forgiveness structures. However, simplified applications do not exempt your business from mandatory audit-retention compliance checks.

The SBA explicitly mandates that borrowers must retain all documentation submitted with their loan application, all records proving the certification of eligibility, and all documents supporting their forgiveness application for $6 from the date the loan is fully forgiven or repaid. Because many loans were forgiven in late 2020 and throughout 2021, this legal document retention requirement runs directly through 2026 and 2027.

If the SBA conducts a review, you must instantly provide verification of your full-time-equivalent (FTE) employees, wage rates, and payroll ledgers, as well as utility, lease, and mortgage interest payments. If your records are unorganized or missing, the SBA can retroactively disallow forgiveness, demanding full repayment of the principal plus accrued interest.
