Final answer:
You do not have to file taxes as a single person if your adjusted gross income is less than the sum of the standard deduction and exemption for that year, as was the case in 2010 when they totaled $9,350 for a single person. Always check the current year's tax code or consult a professional for your specific requirements.
Step-by-step explanation:
In certain situations, you may not be required to file taxes as a single person. Specifically, if your income is below a certain threshold, you may be exempt from filing. For instance, according to the tax code, if your adjusted gross income plus the standard deduction and exemption amount to less than the taxable income, you would not owe any federal tax. This scenario was possible when the standard deduction and exemption for a single person totaled $9,350 in 2010. It is important to note that tax regulations can change every year, and income thresholds may differ accordingly, so it's crucial to consult the most current tax year information.
Also, if you earn less than the mandatory filing limit and have no special circumstances requiring you to file (such as self-employment income over a set amount), then you wouldn't need to file a federal income tax return. This reflects the progressive nature of the tax system, where taxes are owed based on the ability to pay. However, always review the latest Internal Revenue Service (IRS) guidelines or consult with a tax professional to understand your specific obligations because not all income levels automatically necessitate filing a tax return.
