Tax Optimization Guide
Tax Optimization Overview
Tax optimization isn’t about cheating—it’s about using the rules as designed. The tax code rewards certain behaviors (saving for retirement, healthcare, homeownership). This guide shows you how to capture those benefits.
The Tax-Advantaged Account Priority
Use accounts in this order to minimize lifetime taxes:
- 401(k) to employer match — Instant 50-100% return (free money)
- HSA to max — Triple tax advantage (deduction + growth + withdrawal)
- 401(k) to max — $23,000/year (2024)
- Roth IRA to max — $7,000/year (2024), tax-free growth
- Taxable brokerage — After tax-advantaged space exhausted
See Tax-Advantaged Accounts for detailed explanations.

The Big Three Deductions
1. Retirement Contributions
| Account | 2024 Limit | Tax Benefit |
|---|---|---|
| Traditional 401(k) | $23,000 | Deduction at marginal rate |
| Traditional IRA | $7,000 | Deduction (income limits apply) |
| SEP-IRA (self-employed) | $69,000 or 25% of income | Deduction |
Impact: Maxing a 401(k) at 24% bracket saves $5,520 in taxes.
2. Health Savings Account (HSA)
| Status | 2024 Limit | Tax Benefit |
|---|---|---|
| Individual | $4,150 | Deduction + tax-free growth + tax-free withdrawal |
| Family | $8,300 | Same triple benefit |
Impact: HSA contributions are the only “triple tax-advantaged” account. Use it.
3. Standard vs. Itemized Deductions
| Filing Status | 2024 Standard Deduction |
|---|---|
| Single | $14,600 |
| Married Filing Jointly | $29,200 |
| Head of Household | $21,900 |
Itemize only if: Mortgage interest + state/local taxes + charitable giving + medical expenses > standard deduction.
Tax-Efficient Investment Strategies
Asset Location
Place investments in the right account type:
| Investment | Best Location | Why |
|---|---|---|
| Bonds / Bond funds | 401(k), IRA | Interest taxed as income |
| REITs | 401(k), IRA | Dividends taxed as income |
| High-turnover funds | 401(k), IRA | Frequent capital gains |
| Index funds | Taxable | Low turnover, qualified dividends |
| International stocks | Taxable | Foreign tax credit available |
| Municipal bonds | Taxable | Already tax-free |
Tax-Loss Harvesting
When investments drop, sell and immediately buy a similar (not identical) fund:
- Sell losing investment — Realize the loss
- Buy similar fund — Stay invested (e.g., swap S&P 500 for Total Market)
- Use loss to offset gains — Reduces tax on winners
- Carry forward excess — Up to $3,000/year against income
Timing Strategies
Income Shifting
| Strategy | When to Use |
|---|---|
| Defer income | High-income year (push bonus to January) |
| Accelerate income | Low-income year (exercise options, sell assets) |
| Roth conversion | Low-income year (convert traditional to Roth) |
Deduction Timing
| Strategy | When to Use |
|---|---|
| Bunch charitable giving | Every other year to exceed standard deduction |
| Prepay property taxes | December (if itemizing) |
| Accelerate medical expenses | If close to 7.5% AGI threshold |
Common Tax Mistakes
Not contributing to 401(k) match
Cost: Literally free money left on table.
Fix: Contribute at least enough to get full employer match before anything else.
Ignoring HSA
Cost: Missing the only triple tax-advantaged account.
Fix: If you have a high-deductible health plan, max your HSA. Use it as a stealth retirement account.
Holding bonds in taxable accounts
Cost: Bond interest taxed at ordinary income rates (up to 37%).
Fix: Put bonds in tax-advantaged accounts, stocks in taxable.
Not harvesting losses
Cost: Paying unnecessary capital gains taxes.
Fix: Harvest losses in December (or anytime), carry forward indefinitely.
Forgetting state taxes
Cost: Missing state-specific deductions and credits.
Fix: Check your state’s 529 deduction, property tax circuit breakers, and other state-specific benefits.
