U.S. Tax System: Taxes are a fact of life in the U.S., but the system doesn’t have to feel overwhelming. This guide will break down the basics of how taxes work, the role of the IRS, and key tax terms every taxpayer should know.
What is the IRS?
The Internal Revenue Service (IRS) is the federal agency responsible for collecting taxes and enforcing tax laws passed by Congress. Think of them as the “tax authority” that ensures compliance with tax regulations.
Their main responsibilities include:
- ✅ Processing tax returns submitted by individuals and businesses.
- ✅ Issuing refunds to taxpayers who overpay taxes.
- ✅ Auditing tax filings to ensure accuracy and detect fraud.
- ✅ Collecting unpaid taxes from those who owe.
While the IRS may seem intimidating, most interactions are straightforward, such as filing your annual tax return or receiving a refund.
Federal vs. State Taxes: What’s the Difference?
In the U.S., you’ll pay taxes at two main levels:
- 🟢 Federal Taxes: Fund national programs like defense, Social Security, and Medicare.
- 🟢 State Taxes: Each state has its own tax rules. Some states (e.g., Texas, Florida) have no income tax, while others (e.g., California, New York) impose higher rates.
You may need to file both federal and state tax returns, depending on where you live and work.
Key Tax Terms Every Taxpayer Should Know
1. Adjusted Gross Income (AGI)
Your total income from all sources (wages, investments, freelance work) minus specific deductions, such as student loan interest or retirement contributions.
📌 Why it matters: AGI determines eligibility for many tax credits and deductions.
2. Taxable Income
Your AGI minus either the standard deduction or itemized deductions. This is the income amount used to calculate your tax liability.
✅ Example Calculation:
- AGI: $50,000
- Standard Deduction (2023, Single Filer): $13,850
- Taxable Income: $36,150
3. Tax Withholdings
The money your employer automatically deducts from your paycheck and sends to the IRS and state tax agencies throughout the year.
📌 Why it matters: If too much is withheld, you get a refund. If too little, you may owe taxes at the end of the year.
4. Tax Refund
If you overpaid taxes throughout the year, the IRS will issue a tax refund when you file your return.
🚨 Common Myth: A tax refund isn’t “free money.” It’s simply a return of the excess amount you paid in taxes.
