Tax & Compliance Reminders: Stay Ahead of Q3 Deadlines and Vendor Reporting

As we move through the third quarter of the year, it’s important for businesses to stay proactive about upcoming tax deadlines and compliance requirements. Staying organized now can help avoid last-minute stress, penalties, and cash flow surprises.

⏰ Important Q3 Tax Deadlines: September 16th

For most businesses operating on a calendar year, September 16th is the deadline for several critical tax payments and filings, including:

• Q3 estimated tax payments for individuals, sole proprietors, partnerships, and corporations

• Certain corporate tax returns (if extended from April 15th)

Missing these deadlines can lead to penalties and interest, so mark your calendar and plan accordingly.

📝 W-9 and 1099 Preparations: Start Now, Don’t Wait!

In addition to tax payments, Q3 is a great time to start collecting and organizing vendor information, specifically W-9 forms. These forms provide the taxpayer identification numbers (TINs) your business needs to prepare accurate 1099 filings at year-end.

Why start early?

• Ensures you have accurate vendor data on file

• Avoids scrambling for information during the busy year-end period

• Helps prevent errors or delays in 1099 filings, which can trigger IRS penalties

Make it a priority to request W-9 forms from all applicable vendors and contractors well before the end of the year. This simple step saves time and stress later.

✅ Tips to Stay Compliant and Organized

• Set calendar reminders for all relevant tax deadlines

• Regularly update and verify your vendor W-9 forms

• Use accounting software or tools to track payments and vendor info

• Work closely with your accountant or tax advisor to confirm filing requirements
