Does Mary need to file a tax return based on her gross income? A quick, practical guide

Picture this: Mary earns money throughout the year, and she wonders if she’s required to file a tax return. The question usually comes in one of two flavors: a tidy yes or a neat no. In Mary’s case, the right answer is yes—because her gross income crosses the IRS threshold for the year. But what does that really mean, and how do you know where you stand?

What is a filing threshold, anyway?

Let me explain it in simple terms. The IRS sets income thresholds to decide who must file a tax return. These thresholds aren’t fixed for everyone; they depend on two main things:

• Filing status (are you single, married filing jointly, married filing separately, head of household, or a qualifying widow/widower?)

• Age (whether you’re under 65 or 65 and older)

In the real world, those thresholds change a little each year. They’re tied to the year’s rules and to the standard deduction amount for your situation. The key idea is straightforward: if your gross income is above the threshold for your situation, you generally must file a return. If you’re below it, you usually don’t have to—though there are other reasons you might still want to file.

Mary’s case, step by step

Mary’s question comes down to one fact: is her gross income above the threshold for her filing status and age? If yes, then she’s in the group that must file a tax return. If no, she wouldn’t be required to file based on income alone.

Here’s why the answer is B, not A:

• The threshold isn’t a single number that fits everyone. It depends on who you are and how you live. Mary’s filing status and age determine what amount of gross income would trigger a filing requirement.

• The option that says she’s not required because she’s older than 65 (option C) would only apply if the threshold were higher or lower due to age in a given year. In most years, age 65 or older affects the standard deduction and sometimes the threshold, but the deciding factor is still whether her income exceeds the applicable threshold.

• The idea that she would only file if Sandi files (option D) doesn’t hold water. Each person’s filing duties hinge on that person’s own income and status. One person’s filing decision doesn’t force another to file.

So, the practical takeaway for Mary is simple: if her gross income is above the current year’s threshold for her status and age, she must file. If it isn’t, she might not be required to file based on that measure alone. And yes, thresholds vary from year to year, so it’s always smart to check the latest figures.

Why age can’t magically override the threshold

You might wonder if turning 65 automatically changes everything. It doesn’t erase the rule—it just changes the numbers a bit, in some cases. The tax code often provides a higher standard deduction for seniors, and that, in turn, can influence whether you’re above or below the threshold. But the system keeps the same basic logic: filing is required if income passes the threshold for your situation. Being older can make filing less onerous in some respects (because you get a larger deduction, credits, or other benefits), but it doesn’t let you skip filing solely because you’re 65 or older if your gross income still crosses the threshold.

Other reasons you might file even when you’re under the threshold

Even if you fall below the threshold, there are scenarios where filing is worthwhile:

• You want to claim a refund or refundable credits. If you had taxes withheld from your pay, you might be due a refund.

• You qualify for credits you couldn’t claim otherwise. Earned Income Tax Credit (EITC), education credits, or health coverage credits can sometimes be worth filing for.

• You had self-employment income. If you earned money as a self-employed person, you might have to file and pay self-employment tax, even if your gross income seems small.

• You’re curious about your tax history. Filing can help you establish a record with the IRS and keep things tidy for future years.

If you’re a student learning about these topics, here’s a useful mindset: the threshold tells you when the door is open to file without penalties for not filing. But filing can still open doors to credits or refunds that are worth pursuing.

Where to check the numbers for the current year

The moment you want to confirm whether you must file, check reliable sources. The IRS publishes the Do I Need to File a Tax Return? guidance for each year, and it explains the thresholds in plain language. You’ll also see references to the year’s standard deduction amounts and any special considerations for age, filing status, and special scenarios.

A few practical tips:

• Look up your filing status and age, then find the current year’s threshold that matches. If your income is above that line, you’re generally in the filing camp.

• If you’re unsure, use the IRS tool or talk to a tax professional. It’s worth a moment of confirmation rather than guessing.

• Don’t forget the other angles. Even when you don’t have to file, there can be benefits to doing so.

Relatable examples to connect the dots

Think of it like joining a club with entry requirements. If you meet the entry bar, you’re eligible to sign up. The club lets you access certain perks—exclusive events, newsletters, or discounts. In taxes, meeting the threshold means you file a return, and filing sometimes unlocks credits or refunds that you wouldn’t get otherwise. It’s not about guilt or “doing taxes,” it’s about making sure you’ve paid what you owe and can benefit from what you’re eligible for.

For students, a quick aside: the idea of thresholds and credits shows why tax topics aren’t just about numbers. They’re about understanding rules that save money and ensure fairness. It’s the same reason people study the basics of taxes early on—the structures you learn now can map onto more complex scenarios later. And yes, it’s perfectly fine to feel a little rusty at first; tax rules are a lot to take in, but they become intuitive with examples and practice.

Putting the concept into a simple checklist

Here’s a compact way to think about Mary’s situation and similar cases:

• Step 1: Determine your filing status (single, married, etc.) and your age.

• Step 2: Find the current year’s filing threshold for that status and age.

• Step 3: Compare your gross income to the threshold.

• Step 4: If income is above the threshold, you generally must file a tax return.

• Step 5: If income is below the threshold, consider other filing triggers (withheld taxes, credits, self-employment income, etc.).

• Step 6: When in doubt, verify with the IRS tool or a tax professional.

A few more notes for clarity

• The question we started with is a great example of a common test-like scenario: a single factor—income—driving the need to file. In real life, you’ll also weigh other factors, like whether you’re owed a refund, whether you’re eligible for credits, or whether you must report certain kinds of income.

• The “Yes, because her income exceeds the threshold” answer isn’t about a mysterious rule; it’s about applying a simple test: is gross income above the line? If yes, file; if no, usually not.

• It’s normal to feel overwhelmed at first. The IRS provides user-friendly resources, and many schools and organizations in the Intuit Academy ecosystem cover these basics with practical examples. The goal is to help you recognize the pattern: thresholds are context-specific, but the logic is consistent.

Takeaway for students exploring these topics

• Filing requirements hinge on thresholds that combine your income, filing status, and age. Mary’s case is a textbook example: she must file because her income crosses the threshold that applies to her situation.

• Age can influence the numbers, but it doesn’t nullify the core rule. Thresholds exist to ensure tax systems capture the right filings without creating needless complexity.

• Even when you’re not required to file, it’s worth evaluating your specific situation for potential refunds or credits.

• Always verify with up-to-date IRS guidance for the exact numbers each year. The landscape can shift, and staying current pays off.

Bottom line

Mary’s situation is a clean illustration of how the IRS determines filing requirements. The key takeaway is simple and practical: if your gross income surpasses the applicable threshold for your filing status and age, you generally need to file a tax return. If it doesn’t, you usually won’t be required to, though there are exceptions and potential benefits to filing anyway.

If you’re exploring these ideas as part of your study of tax concepts, think of thresholds as the starting line. They tell you when a return is in scope. The rest of the journey—credits, deductions, withholdings, and refunds—falls into place once you know whether you’re crossing that line. And as you become more comfortable with the terminology—gross income, filing status, age—I bet you’ll find the rules start to feel a little less intimidating and a lot more navigable.
