Description


S-Corporations – Pen to Paper Preparation of Form 1120-S and Related Forms : 


Moving from a corporate trial balance to a perfectly reconciled IRS Form 1120-S can be a daunting, error-prone task. Without a clear framework, matching operational book data to the rigid pages of an S-Corporation return often leads to costly math errors, mismatched K-1s, and unexpected IRS notices.

Whether you are a tax professional wanting to understand the underlying mechanics beneath your tax software, or an ambitious business owner preparing your own return, this deep-dive webinar removes the guesswork. We will go "pen-to-paper," stripping away automated software shortcuts to look at the exact mechanics of Form 1120-S.You will learn exactly how to map a profit and loss statement to Page 1, handle complex pass-through items on Schedule K, balance the books on Schedule L, and confidently execute tricky M-1 and M-2 reconciliations.

This course will reflect the most current regulations and guidance. Any updates or changes to relevant laws or requirements will be fully incorporated into the content to ensure accuracy and compliance.
