At A Bigger Bottom Line, we’re all about helping you stay ahead, keep your books clean, and avoid tax-time surprises. Here are a few reminders and insights we think you’ll want to know as we head into the latter half of the year:

🔹 1. September 15, 2025: Q3 Estimated Tax Payment Due

Yep — it’s that time again. If you’re making estimated tax payments to the IRS, your Q3 deadline is September 15.

✅ Make your payment here: IRS Direct Pay

Not sure how much to pay? We recommend reviewing your year-to-date financials or reading up on how to calculate your estimated taxes accurately — it’s better than guesstimating and facing penalties later.

🗓️ And don’t forget: the final quarterly payment of the year is due on January 15, 2026 (that covers income earned in September through December).

📌 And yes — state estimated payments are also due, if they apply to you.

🔹 2. October 15th, 2025: Deadline to file your Extended 2024 Tax Return

If you chose to file an extension request on your 2024 Tax Return, this is the due date for filing your Tax Return.

If you need help finalizing your Year End Financials, get in touch with our team. If you have not approved your Year End 2024 Financials, be sure to login to the portal and see if there are any pending To-Dos or questions related to your financials. Make sure your CPA has access to your accounting software and has confirmed receipt of your FINAL financials so they can start filing your Tax Return.

🔹 3. S Corporation Owners: Equal Distributions Are a Must

This one’s important if you have an S corporation with multiple shareholders.

Distributions must be proportional to each owner’s share. If you start paying out unequal amounts — even with a written agreement — you risk accidentally invalidating your S election by creating two “classes” of stock (which is a big no-no for S Corps).

🔹 4. It’s Proactive Planning Season

Before the holidays hit and the year flies by, we’ll be checking in to see how your 2025 is shaping up. This is the perfect window to explore any tax-smart strategies and make data-informed decisions.

So here’s your nudge: catch up on your books now. Having clean, up-to-date records makes it way easier to plan proactively and save strategically.

🔹 5. Is Your S Corp Salary Still Reasonable?

If your business has grown this year, it might be time to revisit your reasonable compensation.

There’s no magic number or flat percentage. The IRS expects data-driven justification — and so do we. We use tools like RCReports to benchmark salaries and keep our clients compliant. We put together a helpful overview of RCReports Tool for S Corporation Compensation on how it works and why it matters and there, you can also find a link to RCReports’ case studies to see real-world examples in action.
