Your client is a partnership, ARP Associates, which is an engineering consulting firm. Generally, ARP bills clients for services at the end of each month. Client billings are about $50,000 each month. On average, it takes 60 days to collect the receivables. ARP's expenses are primarily for salary and rent. Salaries are paid on the last day of each month, and rent is paid on the first day of each month. The partnership has a line of credit with a bank, which requires monthly financial statements. These must be prepared using the accrual method. ARP's managing partner, Amanda Sims, has suggested that the firm also use the accrual method for tax purposes and thus reduce accounting fees by $600. Assume that the partners are in the 35% (combined Federal and state) marginal tax bracket. Complete the letter to your client which outlines which method should be used for its tax return.
