## ASSET LOCATION BASICS

```
WHAT IS ASSET LOCATION?
══════════════════════════════════════════════════════════════

Asset Allocation: WHAT you own (stocks, bonds, etc.)
Asset Location: WHERE you own it (which accounts)

WHY IT MATTERS:
─────────────────────────────────────────────────────────────
Different investments have different tax characteristics
Different accounts have different tax treatment

Matching them optimally can add 0.3-0.5% annually
Over decades, this compounds significantly!

THE THREE ACCOUNT TYPES:
─────────────────────────────────────────────────────────────
TAXABLE (Brokerage):
• Pay taxes each year on dividends, gains
• Long-term gains taxed at favorable rates
• Can harvest losses
• Foreign tax credit available

TAX-DEFERRED (401k, Traditional IRA):
• No current taxes on growth
• ALL withdrawals taxed as ordinary income
• No capital gains rates
• No foreign tax credit

TAX-FREE (Roth IRA, Roth 401k):
• No current taxes
• No taxes on withdrawals (qualified)
• Best for highest-growth assets
• No foreign tax credit
```

## INVESTMENT TAX CHARACTERISTICS

```
TAX EFFICIENCY OF DIFFERENT INVESTMENTS
══════════════════════════════════════════════════════════════

MOST TAX-EFFICIENT (good for taxable):
─────────────────────────────────────────────────────────────
• Tax-managed stock funds
• Total market index funds (low turnover)
• Municipal bonds
• Individual stocks (no turnover unless you sell)
• ETFs (more tax-efficient than mutual funds)
• Growth stocks (no dividends)

MODERATELY TAX-EFFICIENT:
─────────────────────────────────────────────────────────────
• Broad index funds with some dividends
• International developed stocks
• Balanced funds

LEAST TAX-EFFICIENT (bad for taxable):
─────────────────────────────────────────────────────────────
• Taxable bonds (interest = ordinary income)
• High-yield bonds
• REITs (dividends = ordinary income)
• Actively managed funds (high turnover)
• High-dividend stocks
• Commodities (complex tax treatment)

WHY TURNOVER MATTERS:
─────────────────────────────────────────────────────────────
High turnover = More realized gains = More taxes

Index fund: 3-5% turnover
Active fund: 50-100%+ turnover

In taxable accounts, turnover costs real money
```

## OPTIMAL PLACEMENT RULES

```
GENERAL ASSET LOCATION GUIDELINES
══════════════════════════════════════════════════════════════

TAXABLE ACCOUNTS - Place:
─────────────────────────────────────────────────────────────
✓ Total stock market index funds
✓ Tax-managed funds
✓ International stocks (for foreign tax credit)
✓ Individual stocks
✓ Municipal bonds
✓ Long-term holdings

TAX-DEFERRED (401k/IRA) - Place:
─────────────────────────────────────────────────────────────
✓ Taxable bonds
✓ REITs
✓ High-yield bonds
✓ Actively managed funds
✓ High-dividend stocks
✓ TIPS

ROTH (Tax-Free) - Place:
─────────────────────────────────────────────────────────────
✓ Highest expected growth assets
✓ Small-cap stocks
✓ Emerging markets
✓ Aggressive growth funds
✓ Assets you'll hold longest

THE LOGIC:
─────────────────────────────────────────────────────────────
Taxable: Tax-efficient assets (minimize annual tax drag)
Tax-deferred: Tax-inefficient assets (defer ordinary income)
Roth: Highest growth (maximize tax-free growth)
```

## SPECIAL CONSIDERATIONS

### Foreign Tax Credit

```
INTERNATIONAL STOCKS AND FOREIGN TAX CREDIT
══════════════════════════════════════════════════════════════

THE ISSUE:
─────────────────────────────────────────────────────────────
Foreign stocks pay dividends
Foreign countries withhold taxes
US allows credit for foreign taxes paid

BUT: Only available in TAXABLE accounts!

IN TAXABLE:
─────────────────────────────────────────────────────────────
Foreign taxes withheld → Get credit on US return
Net cost: Reduced or zero

IN TAX-DEFERRED (401k/IRA):
─────────────────────────────────────────────────────────────
Foreign taxes withheld → NO credit allowed
You lose the foreign tax credit permanently

RECOMMENDATION:
─────────────────────────────────────────────────────────────
IF you have enough taxable space:
Hold international stocks in TAXABLE accounts

The foreign tax credit makes up for the dividend taxation
```

### Bonds: It's Complicated

```
WHERE TO PUT BONDS?
══════════════════════════════════════════════════════════════

TRADITIONAL ADVICE: Bonds in tax-deferred
─────────────────────────────────────────────────────────────
Bond interest = ordinary income
Tax-deferred = defer that ordinary income
Makes sense, right?

BUT CONSIDER:
─────────────────────────────────────────────────────────────
Tax-deferred withdrawals = ordinary income anyway
Stocks in tax-deferred lose capital gains benefit

NEWER THINKING:
─────────────────────────────────────────────────────────────
Stocks in tax-deferred may be OK
Because you're trading:
• Ordinary income tax (bonds) for
• Ordinary income tax (stock gains become ordinary at withdrawal)

The benefit is more nuanced than traditionally thought

PRACTICAL APPROACH:
─────────────────────────────────────────────────────────────
• Very high-yield bonds: Tax-deferred
• Investment-grade bonds: Either location reasonable
• Munis: ONLY in taxable
• REITs: Tax-deferred (ordinary income dividends)
```

## EXAMPLE ALLOCATION

```
SAMPLE ASSET LOCATION ($800K total)
══════════════════════════════════════════════════════════════

TARGET: 60% Stocks / 40% Bonds

ACCOUNTS:
─────────────────────────────────────────────────────────────
Taxable brokerage: $200,000
401(k): $500,000
Roth IRA: $100,000

ASSET LOCATION STRATEGY:
─────────────────────────────────────────────────────────────
TAXABLE ($200,000):
• $150,000 - US Total Stock Market Index
• $50,000 - International Developed Index
(Tax-efficient, get foreign tax credit)

401(k) ($500,000):
• $130,000 - US Total Stock Market Index
• $50,000 - International Index
• $320,000 - Bond Index
(Bonds here, tax-inefficient assets)

ROTH IRA ($100,000):
• $50,000 - Small-cap Index
• $50,000 - Emerging Markets
(Highest expected growth, tax-free forever)

TOTALS:
─────────────────────────────────────────────────────────────
Stocks: $480,000 (60%)
Bonds: $320,000 (40%)
✓ Target allocation achieved across accounts
```

## REBALANCING WITH ASSET LOCATION

```
TAX-EFFICIENT REBALANCING
══════════════════════════════════════════════════════════════

PRIORITIZE TAX-ADVANTAGED ACCOUNTS:
─────────────────────────────────────────────────────────────
1. Use new contributions to rebalance
2. Rebalance within 401k/IRA first (no tax impact)
3. Rebalance within Roth (no tax impact)
4. Taxable: Use new money, dividends, harvest losses

AVOID IN TAXABLE:
─────────────────────────────────────────────────────────────
• Selling winners just to rebalance
• Creating short-term gains
• Selling with large embedded gains

LOCATION DRIFT:
─────────────────────────────────────────────────────────────
Over time, location can drift
If taxable stocks grow faster than tax-deferred
You may end up with "wrong" location

Periodic review and adjustment needed
But don't over-trade in taxable accounts
```

## BEST PRACTICES

### Do's ✅
1. **Match tax characteristics** - Efficient in taxable
2. **Use Roth for growth** - Maximize tax-free gains
3. **Claim foreign tax credit** - International in taxable
4. **Rebalance tax-efficiently** - Use tax-advantaged accounts
5. **Consider your whole portfolio** - Across all accounts
6. **Review periodically** - Life changes affect strategy

### Don'ts ❌
1. **Don't put munis in IRAs** - Waste tax exemption
2. **Don't ignore it** - Location adds real value
3. **Don't overthink small accounts** - Focus on large balances
4. **Don't trade excessively** - Tax costs matter
5. **Don't forget RMDs** - Affects future tax-deferred balance
6. **Don't sacrifice allocation** - Location is secondary
