September 2026 Question and Answer

QUESTION:

When is the filing deadline if I requested an extension?

ANSWER:

The deadline is October 15, 2026. Even though you filed for an extension, it’s important that you follow these key rules.

  • No Extra Time to Pay: An extension to file is not an extension to pay. Any taxes owed are still due by the original April deadline to avoid penalties.
  • Estimate Your Tax: You must estimate your total tax liability and pay what you can when submitting the extension to minimize potential failure-to-pay penalties and interest.
  • State Taxes: Check with your state’s tax department, as some automatically accept a federal extension while others require a separate state extension form.

March Mastery: Essential Checklist for Small Business Owners

As the last snowflakes melt and cherry blossoms tease the horizon, March arrives like a double-edged sword for small business owners. It’s a pivotal point—bridging winter’s quiet reflection with spring’s explosive growth. Miss the mark here, and you risk a cascade of compliance headaches, financial blind spots, or missed seasonal opportunities. You’ll emerge stronger, leaner, and primed for a thriving quarter. Let’s break down the must-dos to make this month your launchpad for the second quarter of 2026.

NAIL THOSE TAX DEADLINES: NO EXTENSIONS, NO EXCUSES

March 15th is a key deadline for partnerships and S-corporations, as it marks the deadline for filing Form 1065 and issuing Schedule K-1s to partners. Unlike C-corporations, which have until April without penalties, these entities need to be precise—late filings can result in penalties that quickly add up into thousands of dollars. If your fiscal year ends on December 31st, use this time to reconcile 1099s and collect W-2s early.

Consult your trusted advisors; tools like QuickBooks or TurboTax Business can make preparation easier, but human oversight captures nuances that algorithms overlook. Remember, accurate filings aren’t just about compliance—they provide insights for smarter deductions next year.

QUARTERLY REVIEWS: UNEARTH HIDDEN INSIGHTS

With Q1 wrapping up, March is an ideal time for performance reviews. Review your P&L statements: What’s driving revenue? Where are margins shrinking? Using dashboard tools makes this painless— track KPIs like customer acquisition cost and inventory turnover. Celebrate successes and analyze failures. These reviews aren’t just busywork; they act as your crystal ball, guiding Q2 budgets and adjustments. Dedicate a one-day “finance Friday” to complete this, freeing mental space for growth.

SPRING CLEAN AND DECLUTTER

Spring signals a business deep clean. Audit your physical space: organize your inventory, purge outdated stock, and refresh your storefront to attract warmer foot traffic. Digitally, scrub your CRM for stale leads, optimize your website for mobile spring searches, and secure backups against cyber threats. This renewal boosts efficiency—think 20% faster operations—and signals professionalism to clients. Bonus: it reignites your passion, combating founder fatigue.

March isn’t a sprint; it’s your strategic setup. Tackle these tasks with purpose and watch your small business flourish.
