Tax Planning and Tax-Efficient Strategies
This domain tests whether you can raise after-tax outcomes without raising risk: the correct use of marginal rates, tax-deferred versus tax-free wrappers, capital gains treatment and loss harvesting.
Rates and reliefs
Marginal rate applies to the next unit of income; effective rate is total tax divided by total income. Planning decisions are made at the margin. A deduction reduces taxable income, so its value equals the deduction times the marginal rate; a credit reduces tax directly, so its value is the full amount. Deductions therefore favour higher-rate taxpayers, credits favour lower-rate ones.
Wrapper choice
Contributions to tax-deferred accounts give a deduction now and are taxed on withdrawal; tax-free accounts give no deduction but no tax on qualified withdrawals. The rule: if the tax rate at contribution exceeds the rate at withdrawal, defer; if it is lower, prefer the tax-free wrapper. Asset location follows the same logic - income-producing assets inside shelters, tax-efficient growth assets outside.
Worked example
A client in a 30% marginal band gives 10,000 to charity. As a deduction: tax saved = 10,000 × 0.30 = 3,000, net cost 7,000. As a 2,000 tax credit on a 4,000 donation: tax saved 2,000, net cost 2,000. A 10,000 capital gain realised after a qualifying holding period is taxed at the preferential rate; where an unrealised loss of 4,000 exists in another holding, harvesting it offsets the gain, reducing tax - but a replacement purchase within the wash-sale window disallows the loss, so the client must wait or use a non-identical substitute.
Traps
- Quoting a marginal rate as the client's effective burden.
- Harvesting a loss and rebuying the same security too soon.
- Placing taxable bonds in the unsheltered account while shelters hold cash.
- Ignoring that a Roth-style conversion decision rests on future, not current, rates.
