u/IYC420

I created a single-member LLC in 2025 and I forgot to complete a Schedule C when I did my taxes. The only activity in the LLC was a single cash outflow because made an investment in an Oil & Gas asset with this LLC. The Oil & Gas investment is passive, not active, so it is not tax deductible for me (I have 100% active income).

Am I required to amend my tax return to include the Schedule C showing the cash outflow (expense?), or is it irrelevant because it won't impact my return anyways?

I will be completing a Schedule C next year because I will be reporting income from the investment.

Thanks in advance.
