Answer:
The simplest filing form used by the IRS is Form 1040EZ
Step-by-step explanation:
If a person earns less than $100,000 a year (Robert only earns $12,523), and doesn't have any dependents (Robert is single and apparently has no kids), he/she can file taxes using the Form 1040EZ. Only wages, salaries, tips, taxable interest of $1,500 or less, unemployment compensation and Alaska permanent fund dividends can be included in Form 1040EZ (Robert surely applies), other types of income must be filed using other forms.
