I will admit I've never requested.

Most of my clients who file gift tax reyurns do so on a regukar, if not annual basis.

Last time I needed some - for a 95 year old woman's taxable estate, I had the last 10 years or so only. I definitely had the last one filed which gave me what I needed. I attached the ones I had to the 706. No questions asked. I got a closing letter.
