A blended tax rate of 31.8% does seem unusually high for a taxable income of around $14,000. Here are a few possible reasons:
Additional Income Sources: Other income like dividends, interest, or *capital gains could be taxed at different rates
Self-Employment Taxes: If you have self-employment income, you pay both the employer and employee portions of Social Security and Medicare taxes, totaling 15.3%
Tax Credits and Deductions: Fewer tax credits or deductions than expected can increase your effective tax rate.
*Capital Gains Tax Rates
Short-term capital gains: Taxed at your ordinary income tax rates.
Long-term capital gains: Taxed at 0%, 15%, or 20%, depending on your taxable income
