I am guessing you mean the 1099 since a W9 does not report any type of income, it is like a W4 for LLC's.
If so, the answer would be yes, you would include all payments to one client on one 1099. However, you are saying this is for your client. You would not issue a client a 1099, you would give them a W9 if requested so they can give you a 1099.
If the total amount paid was only $200, there is no need to issue a 1099 as it is less than $600.
Thank you so much, @Vanessa A ! Yes, so just to clarify (this is my first time doing this) and confirm: A client requested a W-9, and asked whether all our payments should be included in my 1099 from her that she will make for my LLC. This is because my LLC was established in October, and we had our first project in September (200 USD). So you say that she should make a 1099 for all the payments from October for the LLC, and the ones before that (before the LLC) do not require a 1099 because it was for less than 600 USD. Is that right?
If you are a single-member LLC, the LLC is considered to be a disregarded entity so you and your LLC are one and the same. If your total receipts for 2021 are $600 or more, the income must be reported on a 1099-NEC. The total can be entered under the LLC.
If, however, you elect to be taxed as a corporation, you would be separate entities. Your income as an individual would be entered on Schedule C and your LLC income would be reported on Form 1120.
