Sending a tax return to arkansas

Why?  Do you need the address to mail it?  Or is your e-file being rejected?

I found these addresses:

• Return Mailing Address:
  

  Arkansas State Income Tax
  P.O. Box 1000
  Little Rock, AR 72203-1000
  
  
• Return Mailing Address without Refund:
  

  Arkansas State Income Tax
  P.O. Box 2144
  Little Rock, AR 72203-2144

   

  I tried exploring the Arkansas tax web site--it is possibly the worst tax site I have ever seen.
