A major reason for the delay of processing your returns is that something is missing and we are unable to file a complete return. If you deliver any information to us after March 15, it is likely that you will receive an extension to October 15. The later your information arrives, the more likely you are to receive an extension. We will make every attempt to complete your returns, but be aware that your tardiness puts you further back in the line. Please provide your files in standard pdf, Microsoft Word or Excel format because we are unable to install additional software to read your files. Please try to deliver all of your missing information to us at the same time. You may e-mail your documents to us at MissingInfo@WallaTax.com.
