A couple reports approximately $150,000 of taxable income each year. They have two children, one 16 years old and the other child age 20. The 20 year old child attends college. This summer, the college student expects to earn $2,000 from summer jobs. Our client has two tax questions: 

(1) based on their older child's summer job earnings, how should they handle their tax return for 2021? Should they include their child's earnings on their joint return or have their older child file a separate return? 

(2) With respect to the firm's tax advice, will the final advisory letter be subject to some type of privilege? 

The clients are concerned that the IRS may request the firm's advisory letter and want to know whether this firm's letter can be protected from disclosure to the IRS.
