C Corp on accrual basis of accounting has a fiscal year end September 30th. C Corp is 100% owned by "Mr. Smith."

Smith wants to establish an SMLLC and chooses a proprietorship whereby to report profits/losses from the SMLLC. The SMLLC has numerous transactions with his C Corp. In general, a proprietorship must be on a cash basis with a calendar year end.

Can the SMLLC choose to report on an accrual basis under these circumstances?
