Understanding Federal Income Tax
The U.S. federal income tax system is progressive, meaning higher income portions are taxed at higher rates. Understanding how tax brackets work is essential for financial planning and avoiding common misconceptions.
Many people mistakenly believe that moving into a higher tax bracket means all their income is taxed at that higher rate. In reality, only income above each bracket threshold is taxed at the higher rate.
Tax Reduction Strategies
Maximize Retirement Contributions
401(k) contributions reduce taxable income. For 2025: $23,000 limit ($30,500 if 50+). Traditional IRA: $7,000 limit ($8,000 if 50+).
Use HSA Accounts
Health Savings Accounts offer triple tax benefits: deductible contributions, tax-free growth, tax-free withdrawals for medical expenses. 2025 limits: $4,150 individual, $8,300 family.
Claim All Eligible Credits
Child Tax Credit ($2,000/child), Earned Income Tax Credit (up to $7,830), education credits, energy credits. Credits reduce tax dollar-for-dollar.
Consider Tax-Loss Harvesting
