Tax calculation is an essential aspect of financial planning for individuals and businesses. Understanding how taxes are calculated can help taxpayers minimize liabilities and maximize deductions. This guide provides a comprehensive overview of tax calculation, including taxable income, deductions, credits, and tax rates.
Taxable income is the portion of your earnings subject to taxation after accounting for deductions and exemptions. It includes:
Earned Income: Salaries, wages, self-employment earnings.
Investment Income: Interest, dividends, rental income, capital gains.
Other Income: Social Security benefits, retirement account withdrawals, alimony (if applicable).
Taxpayers can reduce taxable income by claiming either the standard deduction or itemized deductions. The IRS has increased standard deduction limits:
Single filers: $14,600
Married filing jointly: $29,200
Head of household: $21,900
Itemized deductions may include mortgage interest, medical expenses, charitable contributions, and state/local taxes.
The tax system in the U.S. follows a progressive structure, meaning different portions of income are taxed at different rates. Here are the projected federal tax brackets:
| Tax Rate | Single Filers | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | Up to $11,600 | Up to $23,200 | Up to $16,550 |
| 12% | $11,601 - $47,150 | $23,201 - $94,300 | $16,551 - $63,100 |
| 22% | $47,151 - $100,525 | $94,301 - $201,050 | $63,101 - $100,500 |
| 24% | $100,526 - $191,950 | $201,051 - $383,900 | $100,501 - $191,950 |
| 32% | $191,951 - $243,725 | $383,901 - $487,450 | $191,951 - $243,700 |
| 35% | $243,726 - $609,350 | $487,451 - $731,200 | $243,701 - $609,350 |
| 37% | Over $609,350 | Over $731,200 | Over $609,350 |
Deductions reduce your taxable income (e.g., student loan interest, business expenses).
Tax Credits directly lower your tax bill (e.g., Child Tax Credit, Earned Income Tax Credit, Education Credits).
Key tax credits include:
Child Tax Credit: $2,000 per child under 17, with refundability of up to $1,600.
Earned Income Tax Credit (EITC): Varies based on income and dependents.
American Opportunity Tax Credit (AOTC): Up to $2,500 per student for higher education expenses.
Self-employed individuals must pay Self-Employment Tax (SE Tax), covering Social Security and Medicare contributions (15.3%). Deductions for self-employed taxpayers include:
Home office expenses
Business-related travel and meals
Retirement contributions (SEP-IRA, Solo 401(k))
Short-term capital gains (held <1 year) are taxed at ordinary income rates.
Long-term capital gains (held >1 year) are taxed at 0%, 15%, or 20% depending on income.
Net Investment Income Tax (NIIT): 3.8% applies to high-income earners on certain investment income.
Employees pay FICA taxes:
Social Security: 6.2% (up to $168,600 in earnings)
Medicare: 1.45% (+0.9% on earnings over $200,000 for single filers)
Employers match these contributions, while self-employed individuals pay both portions.
Tax Filing Deadline: April 15
Extension Deadline: October 15 (if filed by April 15)
Payment Options: Online payments (IRS Direct Pay, EFTPS), check, credit card
State tax rates vary widely; some states have no income tax (e.g., Florida, Texas), while others have progressive tax structures (e.g., California, New York).
