Where? Is this an IRS ruling or a court decision?
It's a court ruling....
Words of caution on TTS
Many IRS and state agents don’t understand or respect individuals pursuing qualification as a trading business. While there is no bright line test for TTS, recent trader taxcourtcases better defined the volume of total trades required (720 per year per Poppecourt), frequency of trades (3-4 days per week) and average holding period (under 31 days per Endicottcourt). Once an exam starts, it can snowball into other issues. IRS and some state agents often want to challenge TTS if the trader is not a full-time, extremely active trader. And the IRS or state agent can ask about TTS and other issues for the years before and after the tax year examined. Learn tips for dealing with the IRS and states in Chapter 10.
In the past, too manytradersbrought weak cases to taxcourtand have failed to defend themselves properly. That was certainly the case again recently with Poppe, Assaderaghi, Nelson and Endicott. Serving up easy wins in exams, appeals, private letter rulings and taxcourtencourages the IRS and states to further question businesstradersbased on bad legal precedent. When TTS is too difficult to achieve, consider the alternative strategies discussed in Chapter 9. It’s also very important to have good CPAs and tax attorneys who are experts in trader tax law in your corner.
Watch out for bad tax advice: Over the years, other service providers suggestedtraderscould easily deduct pre-business education expenses using C-Corps. This advice is very wrong. We cover what’s allowed and what’s not in Chapter 5.
