Thank you Vanessa! Really appreciate your help! The construction is still in progress, and I will need to pay extra 100K in 2022. If I put the date of LLC registration as the business begins, how can I claim the extra 100k as start-up in 2022 form 1065? Also, regarding #4, so I should amortize 100K start-up cost in 2021 form 1065 with $0 business income?
