How Tax Calculations Work

The US uses progressive taxation. A single filer earning $100K pays 10% on the first $11,925, 12% up to $48,475, 22% up to $100K. After $15K standard deduction, effective rate is ~13.9%. FICA adds 7.65%.

Tax Planning Examples

Real-world tax planning scenarios:

Salary negotiation

$10K raise from $80K to $90K adds ~$6,700 to take-home pay.

Self-employment tax

Freelancer at $80K profit pays ~30% total effective rate.

Capital gains

$50K long-term gains with $60K other income = 0% federal rate.

Bonus withholding

$10K bonus withheld at 22%. If marginal rate is 24%, owe $200 more.

Tax-Saving Strategies

Proven strategies to reduce your tax burden:

Max retirement contributions

$23.5K in 401k at 22% bracket saves $5,170 in federal tax.

Use an HSA

Triple tax advantage: deductible, tax-free growth, tax-free medical withdrawals.

Harvest tax losses

Offset gains with losses. Up to $3K can offset ordinary income.

Hold investments 1+ year

Long-term rates (0/15/20%) beat short-term rates (10–37%).

Bunch deductions

Combine two years of charitable giving to itemize, then take standard next year.

Common Tax Mistakes

Costly errors to avoid:

Confusing marginal vs effective rate

Marginal is your bracket rate; effective is your actual average — much lower.

Ignoring self-employment tax

Freelancers pay 15.3% FICA plus income tax — budget 25–35% total.

Missing crypto taxes

Every crypto sale, swap, or spend is taxable. Wash sale rule applies in 2026.

Forgetting state taxes

State rates range from 0% (TX, FL) to 13% (CA).

Not adjusting W-4
