Key Takeaways

  • Four primary tax reduction techniques: income shifting, timing strategies, investment selection, and tax-advantaged accounts
  • Income shifting to family members is limited by kiddie tax—unearned income over $2,700 (2025) for children under 19 (or under 24 if full-time student) is taxed at parent's rate
  • Timing strategies include deferring income to lower-income years and accelerating/bunching deductions into high-income years
  • Tax-loss harvesting offsets capital gains with losses, with up to $3,000 of net losses deductible against ordinary income annually
  • Asset location optimizes after-tax returns by placing tax-inefficient investments in tax-advantaged accounts

Tax Reduction Strategies

Effective tax planning requires understanding the four fundamental techniques for reducing tax liability. Each strategy has specific applications, limitations, and timing considerations that financial planners must master for the CFP exam and client service.

The Four Tax Reduction Techniques

TechniqueStrategyKey BenefitPrimary Limitation
Income ShiftingMove income to lower-bracket taxpayersLower marginal rate on incomeKiddie tax, assignment of income doctrine
Timing StrategiesControl when income/deductions occurMatch rates to optimal yearsCash vs. accrual limitations
Investment SelectionChoose tax-efficient investmentsLower effective rate on returnsMay sacrifice optimal allocation
Tax-Advantaged AccountsUse qualified plans, IRAs, HSAsDeferral or exclusion of incomeContribution limits, eligibility rules

Income Shifting Strategies

Income shifting involves moving income from a higher-bracket taxpayer to a lower-bracket taxpayer, reducing the overall family tax burden. The primary methods include:

Shifting to Family Members

  • Employing family members - Pay reasonable wages to children or spouse for legitimate work performed in a family business
  • Gifting income-producing property - Transfer appreciated assets or income-producing investments to lower-bracket family members
  • Family limited partnerships - Shift income through partnership distributions

The Kiddie Tax: A Major Limitation

The kiddie tax significantly limits the effectiveness of shifting unearned income to children. For 2025:

Income LevelTax Treatment
First $1,350Covered by child's standard deduction (tax-free)
Next $1,350 ($1,351 - $2,700)Taxed at child's marginal rate
Above $2,700Taxed at parent's marginal rate

Who is subject to kiddie tax:

  • Children under age 19 at year-end
  • Full-time students under age 24 at year-end
  • Exception: Children with earned income exceeding half their support are NOT subject to kiddie tax

Exam Tip: The kiddie tax only applies to unearned income (interest, dividends, capital gains). Earned income from wages or self-employment is always taxed at the child's own rate.

Assignment of Income Doctrine

The IRS assignment of income doctrine prevents taxpayers from assigning income they have already earned to someone else. Key principles:

  • Income is taxed to the person who earns it (fruit vs. tree analogy)
  • You cannot assign wages to a child after you've earned them
  • Dividends are taxed to the shareholder of record
  • Interest is taxed to the owner of the debt instrument

Timing Strategies

Timing strategies involve controlling when income is recognized or deductions are claimed to minimize taxes across multiple years.

Deferring Income

Postpone receiving income to a future year when your tax bracket may be lower:

  • Defer year-end bonuses to the following year
  • Installment sales spread gain recognition over multiple years
  • Delay exercise of stock options when possible
  • Contribute to traditional retirement accounts (immediate deferral)

Best candidates for income deferral:

  • Expecting lower income next year (retirement, sabbatical, career change)
  • Anticipating lower tax rates in future years
  • Building tax-deferred retirement savings

Accelerating Deductions

Claim deductions sooner to offset high-income years:

  • Prepay deductible expenses (property taxes, mortgage interest)
  • Make charitable contributions in high-income years
  • Pay state estimated taxes before year-end

The Bunching Strategy

Bunching (or clustering) concentrates itemized deductions into a single year to exceed the standard deduction threshold:

Without BunchingWith Bunching
Year 1: $14,000 itemized (take standard)Year 1: $28,000 itemized (itemize)
Year 2: $14,000 itemized (take standard)Year 2: $0 itemized (take standard)
Total deductions: $31,500 ($15,750 x 2)Total deductions: $43,750 ($28,000 + $15,750)

Bunching candidates:

  • Charitable contributions (can be prepaid or use donor-advised funds)
  • Property taxes (subject to $10,000 SALT cap)
  • Medical expenses (if near 7.5% AGI threshold)

Investment Selection for Tax Efficiency

Tax-Efficient vs. Tax-Inefficient Investments

Tax-Efficient (Lower Tax Drag)Tax-Inefficient (Higher Tax Drag)
Index funds (low turnover)Actively managed funds (high turnover)
Growth stocks (no dividends)REITs (ordinary income distributions)
Municipal bonds (tax-exempt)Corporate bonds (taxable interest)
Tax-managed fundsHigh-yield bond funds
Long-term capital gainsShort-term capital gains

Tax-Loss Harvesting

Tax-loss harvesting involves selling investments at a loss to offset capital gains and reduce taxable income:

How it works:

  1. Sell investment with unrealized loss
  2. Use loss to offset capital gains (short-term losses first offset short-term gains)
  3. Excess losses offset up to $3,000 of ordinary income per year
  4. Remaining losses carry forward indefinitely

Wash Sale Rule: You cannot claim a loss if you purchase substantially identical securities within 30 days before or after the sale. The disallowed loss is added to the basis of the replacement security.

Workarounds for wash sale:

  • Wait 31 days to repurchase
  • Buy a similar (but not substantially identical) investment immediately
  • Harvest losses in taxable accounts; don't apply to IRAs

Asset Location Strategy

Asset location places investments in the most tax-efficient account type:

Asset TypeBest LocationReason
Bonds, REITsTax-deferred (Traditional IRA, 401k)Ordinary income taxed at higher rates
High-turnover fundsTax-deferredAvoid current tax on gains
Tax-exempt bondsTaxable accountAlready tax-exempt; no benefit in tax-deferred
Index funds, growth stocksTaxable accountLow turnover, qualified dividends, LTCG rates
Roth accountsHighest-growth investmentsTax-free growth maximizes benefit

Tax-Advantaged Accounts Overview

The fourth technique maximizes use of accounts with special tax treatment:

Account TypeContributionGrowthWithdrawalBest For
Traditional IRA/401(k)Pre-tax deductionTax-deferredTaxable as ordinary incomeCurrent high bracket, expected lower future bracket
Roth IRA/401(k)After-tax (no deduction)Tax-freeTax-free (if qualified)Current low bracket, expected higher future bracket
HSAPre-tax deductionTax-freeTax-free for medicalTriple tax benefit for medical expenses
529 PlanAfter-tax (state deduction varies)Tax-freeTax-free for educationEducation funding

CFP Exam Tip: A comprehensive tax plan typically combines all four techniques—shifting income where appropriate, timing income/deductions strategically, selecting tax-efficient investments, and maximizing contributions to tax-advantaged accounts.
