What Age Do You Start Paying Taxes? Key Factors to Know
Discover when tax obligations begin, influenced by income type, dependency status, and self-employment, to better navigate your financial responsibilities.
Understanding when you need to start paying taxes is crucial for financial planning, especially for young earners stepping into the workforce. While age isn’t the main factor that determines tax obligations, several key elements come into play.
Minimum Income Levels that Trigger Tax Filing
The need to file a tax return depends on income levels, which vary based on filing status and age. For the 2024 tax year, the IRS has set specific thresholds. For single filers under 65, the minimum income level is $13,850, matching the standard deduction. For those 65 or older, the threshold increases to $15,700.
Married couples filing jointly have higher thresholds. If both spouses are under 65, the minimum income is $27,700. If one spouse is 65 or older, the threshold rises to $29,400, and if both are 65 or older, it increases to $31,100. These levels ensure individuals with lower incomes aren’t required to file unnecessarily.
Head of household filers must file if their income exceeds $20,800 (under 65) or $22,500 (65 or older). These thresholds apply to both earned and unearned income, such as wages, dividends, and interest. Failing to file when required can result in penalties and interest on unpaid taxes.
Dependents and Filing Obligations
The IRS has specific rules for dependents, based on the type and amount of income they receive. For 2024, dependents with unearned income over $1,250 must file a return, as must those with earned income above $13,850. If a dependent has both earned and unearned income, they must file if their total income exceeds the larger of $1,250 or their earned income plus $400.
The “Kiddie Tax” applies to unearned income for dependents under 19 (or under 24 if a full-time student), taxing amounts above a certain threshold at the parent’s tax rate. This rule prevents families from exploiting lower tax brackets by shifting income to dependents.
Earned vs. Unearned Income
The distinction between earned and unearned income is vital for tax planning. Earned income includes wages, salaries, tips, and self-employment earnings, which are subject to Social Security and Medicare taxes. In 2024, Social Security is taxed at 6.2% and Medicare at 1.45% for employees, with employers matching these amounts. Self-employed individuals pay both portions, totaling 15.3%.
Unearned income includes returns on investments, interest, dividends, and capital gains. While not subject to payroll taxes, unearned income is taxed differently. Qualified dividends and long-term capital gains are taxed at preferential rates—0%, 15%, or 20%—depending on taxable income. Short-term capital gains are taxed at ordinary rates, which can reach 37% for high-income earners in 2024.
Income type also affects eligibility for certain tax credits and deductions. For instance, the Earned Income Tax Credit (EITC) is available only to those with earned income. Meanwhile, unearned income can impact phase-out thresholds for deductions and credits, influencing overall tax liability.
Self-Employment Filing Needs
Self-employed individuals face unique tax responsibilities, including income taxes, business-related deductions, and quarterly estimated payments. They must file a return if their net earnings exceed $400.
One advantage for the self-employed is the ability to deduct legitimate business expenses like home office costs, travel, and supplies. However, these deductions require detailed record-keeping to meet IRS standards. For example, the home office deduction applies only if the space is used exclusively and regularly for business. Proper documentation can significantly reduce taxable income and, in turn, lower overall tax liability.
