📣 IMPORTANT DEADLINE ALERT – SEPTEMBER 15 (Form 1120‑S / 1065)
S‑Corporations (Form 1120‑S) and Partnerships (Form 1065) that filed an extension must submit their tax return by September 15.

Starting September 16, the IRS applies a monthly penalty per shareholder or partner, even if the extension was approved.

💸 Monthly Penalty (2023–2026):
$235 per month, per shareholder/partner.
For example, an entity with 2 owners would be charged $470 for each month late.

⚠️ Key Points:
- The penalty is charged per full month, even if you’re late by just one day.
- Penalties continue to accumulate until the return is filed.
- Extensions do not protect you from late‑filing penalties.

📑 If you haven’t filed yet, now is the time.
We can help you submit before the deadline and avoid unnecessary penalties.
