Final answer:
Individuals must evaluate their income, age, and filing status to determine the need to file an income tax return. Some individuals might not be required to file but doing so could be advantageous. Filing can lead to potential refunds and establishes an income record.
Step-by-step explanation:
The individuals in question are considering whether they need to file an income tax return, which is contingent upon various factors such as income level, age, filing status, and dependency status as guided by IRS regulations. Each scenario presents a unique set of circumstances:
- Patricia, as a self-employed individual, should file a return since her gross income exceeds $400.
- Mike, being over 65, may not be required to file if his income is below the filing threshold for his age group.
- Ronald, as a dependent, might not need to file, depending on whether his income exceeds the standard deduction for a dependent.
- Sam and Lana's combined income is above the threshold for married filing jointly, so they must file.
- Quinn, as a dependent with unearned income over $1,100, is required to file a return.
Filing a tax return when it's not required can be beneficial if one has had federal income tax withheld or is eligible for refundable credits. Additionally, filing can establish a record of income for future Social Security or loan qualification purposes.
