Tax Planning for High Earners: Keeping More of Your $200K+ Income

Introduction: The High-Income Tax Trap

As your income rises above $200,000, your marginal tax burden accelerates:

$100,000 Income:

• Federal: 12-22% marginal rate
• FICA: 7.65%
• State (California example): 6-9%
• Effective total: 30-35%

$400,000 Income:

• Federal: 32-35% marginal rate
• FICA: 1.45% (Medicare only, Social Security capped)
• State (California): 9.3-10.3%
• Net Investment Income Tax (NIIT): 3.8%
• Effective total: 45-50%

$1,000,000 Income:

• Federal: 37% marginal
• FICA: 1.45% + 0.9% additional Medicare
• State: 10.3-13.3%
• NIIT: 3.8%
• Effective total: 52-55%

Every $1,000 earned = $520-550 to taxes

At high incomes, tax optimization matters more than investment returns. This guide presents the institutional tax planning strategies used by CPAs serving high-net-worth clients.

Part 1: Retirement Account Maximization

Strategy 1: Max All Available Accounts

2024 Contribution Limits:

• 401(k): $23,000 employee deferral
• 401(k) catch-up (age 50+): +$7,500
• IRA: $7,000
• IRA catch-up (50+): +$1,000
• HSA: $4,150 individual / $8,300 family
• HSA catch-up (55+): +$1,000

Maximum for couple (both 50+, family HSA):

• His 401(k): $30,500
• Her 401(k): $30,500
• His IRA: $8,000
• Her IRA: $8,000
• HSA: $9,300
• Total: $86,300

Tax Savings (35% marginal bracket): $86,300 × 35% = $30,205 annual tax reduction

Over 10 years: $302,000 in tax savings Invested at 10%: $481,000 in additional wealth

Strategy 2: Backdoor Roth IRA (For High Earners)

Problem: Direct Roth IRA contributions phased out:

• Single: >$153,000 income
• Married: >$228,000 income

Solution: Backdoor Roth (Legal Loophole)

Process:

Step 1: Contribute $7,000 to Traditional IRA (non-deductible, since your income is too high for deduction)

Step 2: Immediately convert Traditional IRA to Roth IRA

Step 3: Pay taxes on conversion

• If you contributed $7,000 and it didn't grow, tax is $0 (you already paid tax on the contribution)
• If it grew to $7,100, tax on $100 growth

Result: $7,000 in Roth IRA (will grow tax-free forever)

Critical: The Pro-Rata Rule Trap

If you have existing pre-tax money in Traditional/Rollover/SEP IRAs, the conversion is partially taxable.

Example:

• Existing Rollover IRA: $100,000 (pre-tax from old 401k)
• New contribution: $7,000 (after-tax)
• Total IRA balance: $107,000
• Convert $7,000 to Roth
• Taxable amount: $7,000 × ($100,000 / $107,000) = $6,542
• Tax at 35%: $2,290

This defeats the purpose.

Solution:

• Before backdoor Roth, roll existing Traditional/Rollover IRA into current 401(k)
• Once only after-tax money in IRA, proceed with backdoor
• No pro-rata rule applies

Strategy 3: Mega Backdoor Roth (The $69,000 Strategy)

Concept: Contribute up to $69,000 annually to Roth (not $7,000).

Requirement: Employer 401(k) must allow:

1. After-tax contributions (beyond $23,000 limit)
2. In-service distributions or conversions to Roth

Not all plans offer this. Check with HR.

How it works:

2024 Total 401(k) Contribution Limit: $69,000 This includes:

• Employee deferrals: $23,000
• Employer match: $10,000 (example)
• After-tax contributions: Up to $36,000 (to reach $69K total)

Process:

Step 1: Max employee deferral ($23,000 pre-tax or Roth)

Step 2: Employer match ($10,000 example)

Step 3: After-tax contributions

• Contribute additional $36,000 (after-tax, not deductible)
• Goes into 401(k), but not to Roth yet

Step 4: Immediately convert after-tax to Roth 401(k) or roll to Roth IRA

• No tax on conversion (it's after-tax money)
• Now grows tax-free forever

Result:

Annual Roth accumulation:

• Regular Roth 401(k) or IRA: $7,000-$23,000
• Mega backdoor: $69,000

Over 20 years at 10% return:

• Regular Roth: $412,000 (from $7K/year)
• Mega backdoor: $3,942,000 (from $69K/year)

Tax-free wealth difference: $3.5 million

Income requirement: Need ~$400K household income to afford $69K annual contribution (after expenses, taxes).

Strategy 4: Tax-Loss Harvesting

Concept: Sell losing investments to offset gains and reduce taxable income.

Annual Benefit:

• Offset capital gains: Unlimited
• Offset ordinary income: Up to $3,000/year
• Carryforward losses: Unused losses carry to future years

Example:

Investment Activity (2024):

• Stock A: Sold for $40,000 profit (long-term gain)
• Stock B: Currently down $25,000 (unrealized loss)
• Salary: $300,000
• Bonus: $50,000

Without tax-loss harvesting:

• Capital gains tax: $40,000 × 20% (LTCG rate for high earners) = $8,000
• NIIT: $40,000 × 3.8% = $1,520
• Total tax on gains: $9,520

With tax-loss harvesting:

• Sell Stock B: Realize $25,000 loss
• Offset Stock A gain: $40,000 - $25,000 = $15,000 net gain
• Offset ordinary income: $3,000 (limit)
• Remaining net gain: $12,000
• Capital gains tax: $12,000 × 20% = $2,400
• NIIT: $12,000 × 3.8% = $456
• Total tax: $2,856
• Tax saved: $6,664
• Remaining losses: $9,000 carry forward to 2025

Plus: Immediately rebuy similar position (avoiding wash sale rule)

Example:

• Sold: Vanguard S&P 500 ETF (VOO) at loss
• Buy: Schwab S&P 500 ETF (SCHX)
• Similar exposure, not "substantially identical" (avoids wash sale)
• Harvested loss, maintained market exposure

Wash Sale Rule: Can't deduct loss if you buy "substantially identical" security within 30 days before or after sale.

Substantially identical:

• Same stock (Apple → Apple): Yes
• Same ETF (VOO → VOO): Yes

NOT substantially identical:

• Similar ETF different issuer (VOO → SCHX): No
• Same sector different company (Apple → Microsoft): No
• Stock → ETF of same sector: Gray area (consult CPA)

Annual Tax-Loss Harvesting Process:

November 15-December 15:

• Review all taxable account positions
• Identify positions with losses
• Identify positions with gains (to see what losses can offset)
• Harvest losses strategically
• Reinvest in similar (but not identical) securities

Typical savings: $3,000-$15,000/year (depending on portfolio size)

Part 2: Charitable Giving Optimization

Strategy 1: Donor-Advised Funds (DAF)

Concept: Front-load multiple years of charitable giving in high-income year, get immediate deduction, distribute to charities over time.

How it works:

Traditional giving:

• Donate $10,000/year to church
• Deduction: $10,000/year
• Tax savings (35% bracket): $3,500/year

DAF strategy (high-income year):

• Income this year: $500,000 (big bonus/equity compensation)
• Contribute $50,000 to DAF (5 years of giving)
• Deduction: $50,000 this year
• Tax savings (37% bracket): $18,500 this year
• Distribute from DAF: $10,000/year to church over next 5 years

Result:

• Same total giving ($50,000)
• Higher tax savings ($18,500 vs $17,500 over 5 years at lower brackets)
• DAF invested (grows tax-free while waiting to distribute)

Best DAF Providers:

• Fidelity Charitable: $0 minimum, low fees
• Schwab Charitable: $0 minimum
• Vanguard Charitable: $25,000 minimum

Advanced: Donating Appreciated Stock

Instead of donating cash, donate appreciated stock:

Example:

• Stock bought for $10,000
• Current value: $50,000
• Capital gain: $40,000

If you sell and donate cash:

• Capital gains tax: $40,000 × 20% = $8,000
• Donate: $42,000 ($50,000 - $8,000 tax)
• Deduction: $42,000
• Tax benefit: $42,000 × 37% = $15,540
• Net benefit: $15,540 - $8,000 = $7,540

If you donate stock directly:

• Capital gains tax: $0 (avoid by donating)
• Donate: $50,000 worth of stock
• Deduction: $50,000
• Tax benefit: $50,000 × 37% = $18,500
• Net benefit: $18,500

Difference: $10,960 more tax benefit (plus charity receives $8,000 more)

Strategy 2: Qualified Charitable Distributions (QCD) - Age 70.5+

For retirees with IRAs:

Problem: Required Minimum Distributions (RMDs) force taxable withdrawals.

Solution: Distribute directly from IRA to charity (up to $100,000/year):

• Counts toward RMD
• Not included in taxable income
• No deduction (but better than deduction for high earners)

Example:

• RMD: $40,000
• Donate $15,000 via QCD
• Take $25,000 cash distribution
• Taxable income: $25,000 (not $40,000)
• Tax saved: $15,000 × 32% = $4,800

Better than deduction:

• Itemized deduction for $15,000 donation: Saves $4,800
• But you paid tax on $40,000 distribution: Cost $12,800
• Net cost: $8,000

Vs QCD:

• Tax on $25,000 distribution: $8,000
• No tax on $15,000 QCD: $0
• Net cost: $8,000

Plus benefits:

• Lowers AGI (affects Medicare premiums, Social Security taxation)
• Simpler than itemizing

Part 3: Entity Structure for Business Owners

S-Corporation Tax Savings

Scenario: Self-employed consultant earning $250,000/year

As Sole Proprietor (Schedule C):

• Self-employment tax: 15.3% on first $168,600 = $25,795
• Self-employment tax: 2.9% on remaining $81,400 = $2,361
• Total SE tax: $28,156
• Plus income tax: ~$50,000
• Total tax: $78,156 (31% effective)

As S-Corporation:

Setup:

• Pay yourself W-2 salary: $120,000 (reasonable compensation)
• Payroll taxes: $120,000 × 15.3% = $18,360
• Distribution (not subject to payroll tax): $130,000
• Total payroll tax: $18,360
• Plus income tax: ~$50,000 (same)
• Total tax: $68,360

Savings: $9,796/year

Over 10 years: $97,960 Invested at 10%: $156,000

Requirements:

• File S-Corp election (Form 2553)
• Run payroll (can use Gusto $40/month)
• File separate business tax return (1120S)
• Pay yourself "reasonable compensation" (can't pay $20K salary on $250K profit, IRS audits)

Costs:

• Setup: $500-2,000
• Annual compliance: $1,500-3,000 (CPA, payroll)
• Net savings: $6,500-8,000/year

Worth it at $100K+ business profit.

Solo 401(k) for Self-Employed (Maximize Contributions)

If self-employed, you can contribute as employee AND employer:

Contribution room:

• Employee deferral: $23,000
• Employer profit-sharing: 20% of net self-employment income (up to $69,000 total combined)

Example:

Self-employment income: $200,000

Contributions:

• Employee: $23,000
• Employer: 20% of $200K = $40,000
• Total: $63,000

Vs W-2 employee (can only do $23,000):

• Extra tax-deferred: $40,000
• Tax savings: $40,000 × 35% = $14,000

This is massive.

If business earns $250K+:

• Max combined contribution: $69,000
• All tax-deductible
• Tax savings: $69,000 × 35-37% = $24,150-25,530

Part 4: Multi-State Tax Optimization

The No-State-Income-Tax Advantage

Zero income tax states (2024):

• Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming
• New Hampshire (dividends/interest only)

High tax states:

• California: 13.3% top rate
• New York: 10.9%
• New Jersey: 10.75%
• Hawaii: 11%
• Oregon: 9.9%

Arbitrage opportunity:

Income: $300,000

• California tax: $30,000 (10% effective)
• Texas tax: $0
• Savings: $30,000/year

Over 20 years: $600,000 Invested at 10%: $1.72 million

Considerations:

Can't just "claim" Florida residency while living in California.

States audit this aggressively. Must:

• Spend >183 days/year in new state
• Change driver's license
• Register vehicles
• Register to vote
• File declaration of domicile
• Move important docs (wills, trusts)
• Close accounts in old state

For remote workers: Massive opportunity

If your job is remote:

• Move from NYC to Florida
• Same salary, zero state tax
• $25,000-40,000/year saved

Statutory Residency Traps

New York: Maintain permanent place of abode + spend ANY time in NY = resident

Example:

• Live in Florida 300 days
• Keep apartment in NYC, visit 50 days
• NY claims you're resident (permanent abode + visits)
• Owe NY tax on 100% of income

California: Extremely aggressive residency claims.

Safe harbor: If you leave California:

• Sell/rent your home
• Don't return for >183 days/year
• Establish domicile elsewhere
• California can't claim you

Risky: Keep California home, claim Nevada residency:

• California audits
• Burden on you to prove you left

For high earners (>$500K), worth consulting tax attorney on residency change (saves $50K-65K/year in CA).

Part 5: Investment Tax Efficiency

Asset Location Optimization

Concept: Put tax-inefficient investments in tax-advantaged accounts, tax-efficient in taxable accounts.

Tax-Efficient Assets (Taxable Account):

• Index funds (low turnover, minimal distributions)
• Municipal bonds (tax-free interest)
• Growth stocks (no dividends, only capital gains when YOU sell)
• ETFs (more efficient than mutual funds)

Tax-Inefficient Assets (IRA/401k):

• Bonds (interest taxed as ordinary income)
• REITs (dividends taxed as ordinary income, no qualified dividend treatment)
• Actively managed funds (high turnover = lots of taxable events)
• High-dividend stocks

Example:

$1M portfolio: $500K in 401(k), $500K in taxable

Poor location:

• 401(k): $250K index funds, $250K bonds
• Taxable: $250K bonds, $250K index funds

Optimal location:

• 401(k): $500K bonds (shield 4% interest from 35% tax)
• Taxable: $500K index funds (defer gains indefinitely, pay 20% only when sold)

Annual tax saved:

• Bonds generate 4% interest: $20,000
• Tax on $20,000 at 35% if in taxable: $7,000
• Tax if in 401(k): $0 (deferred)
• Savings: $7,000/year from smart location

Over 30 years: $210,000 saved

Opportunity Zones (For Concentrated Equity Events)

Qualifying events:

• Sell business: $5M+ capital gain
• Exercise ISOs: $2M+ taxable event
• Inherit appreciated stock: $10M+

Strategy: Invest capital gain in Opportunity Zone fund within 180 days:

Tax benefits:

1. Defer capital gains tax until 2026 or sale of OZ investment (whichever sooner)
2. Reduce original gain: 10% reduction if held 5+ years, 15% if held 7+ years (2026 deadline passed, so this benefit mostly gone)
3. Eliminate tax on OZ investment gains: Hold OZ investment 10 years, pay ZERO tax on appreciation

Example:

Sell business: $10M capital gain

Without OZ:

• Federal tax: $10M × 20% (LTCG) = $2M
• NIIT: $10M × 3.8% = $380K
• State tax: $10M × 13.3% (CA) = $1.33M
• Total tax: $3.71M
• Proceeds: $6.29M

With OZ Investment:

• Invest $10M in OZ fund (real estate development in designated zone)
• Defer tax until 2026 (time value of money)
• OZ investment grows to $18M over 10 years
• Pay tax on original $10M gain: $3.71M (in 2026)
• Pay tax on $8M OZ appreciation: $0
• Total proceeds: $18M - $3.71M = $14.29M

Benefit: $8M in additional wealth ($14.29M vs $6.29M)

Risks:

• OZ investments are real estate/business in distressed areas (higher risk)
• 10-year lockup (very illiquid)
• Fund fees (2%+ annually)
• Due diligence critical (some OZ funds are scams)

Only for ultra-high earners with $2M+ concentrated gains.
