Revenue Sources and How They Work

1. Individual Income Taxes
   • Contribution: $2.64 trillion (54% of 2024 federal revenue, Treasury)
   • How It Works: Levied on wages, salaries, and investment income under the Internal Revenue Code, this tax scales via progressive brackets—10% to 37% for incomes from $11,600 to $609,350+ (2025 rates, IRS). Employers withhold via payroll; self-employed file quarterly. The IRS collected $2.2 trillion in 2023—54 million returns processed by March 31, 2024—funding everything from defense to Medicare.
2. Social Insurance Taxes (Payroll Taxes)
   • Contribution: $1.72 trillion (35% of 2024 revenue)
   • How It Works: Funds Social Security (6.2% employee, 6.2% employer) and Medicare (1.45% each)—capped at $168,600 for Social Security in 2025. Self-employed pay 15.3% total (SECA). In 2024, $1.4 trillion flowed to trust funds—FICA taxes hit 92 million workers, per SSA—securing retiree benefits and healthcare.
3. Corporate Income Taxes
   • Contribution: $392 billion (8% of 2024 revenue)
   • How It Works: A 21% flat rate (post-2017 TCJA) on corporate profits—$1.87 trillion in taxable income reported in 2023 (IRS). Companies like Exxon Mobil (XOM) at $119 pre-market file quarterly estimates; loopholes (e.g., R&D credits) cut effective rates to 12% for some (Tax Foundation). Revenue funds infrastructure and defense.
4. Excise Taxes
   • Contribution: $87 billion (2% of 2024 revenue)
   • How It Works: Levied on specific goods—$0.184/gallon gasoline tax (Highway Trust Fund), $1.01/pack cigarettes (FDA)—collected at production or sale. In 2024, $34 billion from fuel taxes rebuilt roads; alcohol and tobacco added $15 billion—sin taxes curb use while padding coffers.
5. Customs Duties (Tariffs)
   • Contribution: $60 billion (1% of 2024 revenue)
   • How It Works: Taxes on imports—20% on China since February 4, 2025 (Trump EO)—collected by Customs Service at ports. In 2023, $48 billion flowed from $2.4 trillion in imports (CBP); X posts note: “Tariffs hit China hard!” Funds offset trade deficits—$80 billion projected for 2025.
6. Estate and Gift Taxes
   • Contribution: $26 billion (<1% of 2024 revenue)
   • How It Works: A 40% tax on estates over $13.61 million (2025 exemption) and gifts above $18,000 annually—$23 billion collected in 2023 from 2,500 estates (IRS). Wealth transfers fuel this niche stream—X buzzes: “Rich pay up!”
7. Treasury Securities (Borrowing)
   • Contribution: $1.2 trillion (new debt issuance, 2024)
   • How It Works: Deficit spending—$1.8 trillion in 2024 (CBO)—is financed by selling Treasury bills, notes, and bonds to investors, banks, and foreign governments (e.g., Japan, $1.1 trillion holder). Interest at 4.5% on 10-year notes (March 2025) adds $600 billion annually—debt hit $34 trillion by January.
8. Federal Reserve Earnings
   • Contribution: $80 billion (2024 estimate)
   • How It Works: The Fed remits profits from interest on $7.5 trillion in securities (mostly Treasuries) to the Treasury—$82 billion in 2023. Open market ops and bank reserves drive this—X posts: “Fed’s a cash cow!” Funds offset borrowing costs.
9. Fees and Fines
   • Contribution: $40 billion (<1% of 2024 revenue)
   • How It Works: Collected via licenses (e.g., $200 FCC spectrum fee), park fees ($5 Yosemite entry), and penalties—$1.2 billion from SEC fines in 2023 (e.g., insider trading). X notes: “Small but steady!”
10. Miscellaneous (Asset Sales, Royalties)
    • Contribution: $15 billion (<1% of 2024 revenue)
    • How It Works: Oil leases ($8 billion from Gulf rigs, BOEM), land sales ($2 billion, BLM), and postal revenue ($70 billion, USPS, offset by costs)—X buzzes: “Gov’s got side hustles!”

Markets hum—XOM ($119), Lockheed Martin (LMT) ($600), Intel (INTC) ($23.41)—revenue streams fuel stability. GLHR Investing Team’s got your edge—grasp the flow!
