Preferential Rate Basics

Explain why capital gains and qualified dividends need separate review from ordinary conversion income.

3 points

Long-term capital gains and qualified dividends can use preferential tax rates

Long-term capital gains and qualified dividends may be taxed under preferential rate rules that differ from ordinary income brackets.

Review note: Use IRS worksheets, tax software, or professional review when a year includes capital gains or qualified dividends.

Topic: Preferential rates

Ordinary income and preferential income can interact

Roth conversion income is generally ordinary income, but it can change the taxable income context used to evaluate preferential-rate income.

Review note: Review the full return, not only the conversion amount.

Topic: Preferential rates

Filing status affects rate-band review

Capital gain rate bands and ordinary income brackets can vary by filing status.

Review note: Bring filing status, income estimates, and investment records to review.

Roth conversion income can reduce room in lower capital gain rate bands

Adding ordinary conversion income may push more taxable income into ranges where preferential income is taxed differently.

Topic: Income stacking

Partial conversions may have different capital gain effects

Different conversion amounts can interact differently with existing capital gains and qualified dividends.

Review note: Run multiple scenarios when capital gains are expected.

Topic: Income stacking

Taxable income input should reflect known portfolio events

If portfolio gains are expected, the calculator's taxable income assumption should be reviewed before conversion income is added.

Review note: Update the income baseline after brokerage estimates or CPA projections are available.

Worksheet Review

Point users to worksheet and tax-software review without embedding a partial tax-return engine.

3 points

Qualified Dividends and Capital Gain Tax Worksheet review is separate

Capital gain and qualified dividend tax calculations can require worksheets or tax software beyond a simple marginal bracket estimate.

Review note: Do not use the Roth conversion calculator as a substitute for worksheet-based return preparation.

Topic: Worksheet review

Schedule D records can affect the final result

Realized gains, losses, carryovers, and capital gain distributions may affect final tax treatment.

Review note: Bring Schedule D history, brokerage statements, and capital loss carryover records.

Topic: Worksheet review

Qualified dividend classification matters

Not every dividend is treated as a qualified dividend for tax purposes.

Review note: Use Form 1099-DIV records and professional review for classification.

Topic: Worksheet review

Portfolio Event Review

Identify investment events that can make conversion comparisons incomplete.

3 points

Large realized gains can change conversion scenario comparisons

Asset sales, fund distributions, rebalancing, and concentrated-stock sales can change the income picture for the conversion year.

Review note: Coordinate conversion scenarios with known portfolio events.

Topic: Portfolio events

Capital loss carryovers may need review

Capital loss carryovers can affect taxable gain calculations but are not modeled by the calculator.

Review note: Bring prior-year returns and carryover schedules to review.

Topic: Portfolio events

NIIT may overlap with capital gain review

Investment income and higher MAGI can also raise NIIT questions for some users.

Review note: Review capital gains and NIIT together when investment income is material.

Topic: Portfolio events

Calculator Boundary

Make clear that the calculator estimates conversion effects, not full capital gain worksheets.

3 points

Calculator does not compute Schedule D or capital gain worksheets

The calculator estimates conversion tax cost, simplified state tax, penalties, projections, and break-even math; it does not prepare Schedule D or capital gain worksheets.

Review note: Use calculator output as a worksheet, not as tax return support.

Topic: Calculator limits

Capital gains should be part of the professional handoff

Users with realized gains, qualified dividends, or fund distributions should add these items to the CPA review packet.

Review note: Bring brokerage statements, tax estimates, and saved calculator scenarios.

Topic: Calculator limits

Income-linked interactions should be reviewed together

Capital gains can overlap with NIIT, IRMAA, ACA premium tax credits, Social Security benefit taxation, RMDs, and state tax.

Review note: Review the full income stack before relying on a single-scenario estimate.
