Is there anything I can do to avoid filing an extension if I know I am missing some information now?

If you already know you will be waiting until the last minute for one or two documents, you may be able to minimize the chance of having to file an extension by providing all other available documents to us as soon as you receive them. By doing so, we can prepare a draft return for you to review and discuss in advance. We may be able to add the missing piece of data or last-minute information and still be able to complete your returns by April 18 (depending on our workload).
