No it doesn't, at least not for tax purposes (unless the LLC elects to be taxed as a corporation). As a disregarded entity, the LLC can not use an accounting period different from the individual. Pub 538 says, "If you file your first tax return using the calendar tax year and you later begin business as a sole proprietor... you must continue to use the calendar year unless you obtain approval from the IRS to change it."
How did he allocate income/expenses last year?
