IRS income thresholds
If you aren't the dependent of another taxpayer, you will have to file a tax return if your gross income is greater than or equal to the sum of your standard deduction and personal exemption. Your total gross income for the year includes all earnings that aren't exempt from income tax. Exemptions are a fixed amount and are the same for all taxpayers eligible to claim them. Standard deductions are also predetermined amounts, but are different for each filing status. If you plan to file a joint return with your spouse, you can use two exemptions, but you must include the income you both earned.
