## **Mistake #10: Not Knowing When to File Amendments vs. Amended Annual Reports**
### **The Mistake:**
Your LLC needs to make a change. You're not sure whether to:

- Do nothing
**You choose wrong, waste money, or fail to make necessary updates.**
### **The Real Cost:**
- **Wrong Filing:** $25-138.75 wasted on incorrect form
- **Incomplete Updates:** Change not properly recorded
- **Compliance Issues:** Records don't match reality
- **Legal Problems:** Incorrect information on file
### **Why This Happens:**

### **Here's the Breakdown:**
**Use ANNUAL REPORT to update:**

- Mailing address
- Registered agent (with new agent's signature)
- Officers/Directors/Managers/Members
- Add or update FEI number
**Use AMENDED ANNUAL REPORT to:**
- Fix errors in current year's already-filed annual report

- Any structural changes to Articles of Organization

- Cost: $25+ (depending on change)
- **Cannot be filed online** - must mail
**Important:** The annual report does not permit you to change the name of your business. To change the name, download and complete the appropriate amendment form
### **Special Case - Entities Formed This Year:**
Business entities formed or effective after January 1st of this year are not due an Annual Report and must select and file the appropriate amendment form by mail
### **How to Avoid It:**
โ
**Determine what you're changing:**
- Address/agent/members? โ Annual report
- LLC name? โ Articles of Amendment
- Made mistake on this year's report? โ Amended annual report
โ
**Check if annual report is due:**
