Convert Pretax to Roth Strategy: How to Evaluate a Roth Conversion
A Roth conversion moves money from a traditional pretax retirement account into a Roth account.
The appeal is straightforward: taxes are generally paid on the amount converted, while qualified future Roth distributions may receive different tax treatment under applicable rules.
The planning question is more complicated.
A Roth conversion can create taxable income today in exchange for potential future tax benefits. Whether that tradeoff makes sense depends on the individual's circumstances.
That is why a convert pretax to Roth strategy should be evaluated as part of a broader tax and retirement plan.
What Is a Roth Conversion?
A Roth conversion generally involves moving funds from a traditional IRA or other eligible pretax retirement account into a Roth IRA.
The amount converted is generally included in taxable income, subject to applicable rules and exceptions.
The conversion therefore creates a tax event.
For someone in a lower current tax bracket who expects higher taxable income later, a conversion may be worth evaluating. For someone already in a high tax bracket, the immediate tax cost may be more significant.
There is no single conversion amount that fits every taxpayer.
Why Timing Matters
Roth conversion planning is closely connected to income timing.
Consider a person who retires in June. Their taxable income in the retirement year may differ significantly from their income during their final full year of employment.
That difference may create a planning window.
Other situations that can affect the analysis include:
Business income changes
Retirement
A business sale
Large capital gains
Temporary reductions in income
Charitable giving
Changes in filing status
This is why multi-year tax planning can be useful.
Evaluate Your Tax Bracket
The immediate tax cost is one of the central considerations.
A conversion may push additional income into a higher marginal tax bracket or affect other tax calculations.
Rather than asking whether Roth conversions are "good" or "bad," consider how much taxable income could be recognized under different scenarios.
For example, an individual might compare:
No conversion
Small annual conversions
A larger one-time conversion
Conversions during lower-income years
Scenario analysis can help clarify the tradeoffs.
Consider Future Retirement Income
A Roth conversion should also be evaluated against expected retirement income.
Potential future income sources include:
Social Security
Pension income
Traditional retirement accounts
Roth accounts
Taxable investment accounts
Business interests
Rental income
If most retirement assets are pretax, future distributions may create significant taxable income.
A Roth conversion may change the composition of retirement assets.
That does not automatically make conversion appropriate. The question is whether the potential future tax benefits justify the current tax cost.
Coordinate With Other Tax Planning
Roth conversion decisions can interact with other financial decisions.
A business owner might be evaluating a sale at the same time. A retiree might be considering charitable giving. A real estate investor might have significant depreciation or other income considerations.
These factors can affect the amount and timing of a potential conversion.
Compound Wealth's tax planning approach emphasizes multi-year planning across business income, retirement considerations, income timing, and significant financial events.
Consider Charitable Giving
Charitable giving can also be relevant.
A retiree with significant pretax retirement assets may want to evaluate charitable goals alongside retirement distributions and tax planning.
The appropriate strategy depends on applicable rules, charitable objectives, account types, and the taxpayer's circumstances.
Coordination with tax and legal professionals can be important for more complex charitable planning.
Think About Estate Planning
Roth conversions can also affect estate planning.
A family may have questions about how traditional and Roth retirement assets could fit into an estate plan, how beneficiaries are designated, and how inherited retirement accounts are treated under current law.
Estate planning should therefore be part of the broader discussion when retirement assets are significant.
A Simple Roth Conversion Framework
Before converting pretax assets, consider these questions:
What is my current taxable income?
Start with a realistic projection for the year.
What might my future income look like?
Consider retirement, business income, investment income, pensions, and other sources.
How much tax would the conversion create?
Model the potential tax impact before deciding on an amount.
How would the conversion affect other planning areas?
Review charitable giving, retirement income, estate planning, and investment allocation.
Where would the conversion tax be paid from?
Funding the tax from outside retirement assets may produce different results from withholding it from the converted amount.
Avoid Making the Decision Based on One Year
Roth conversion planning is often most useful when viewed over several years.
For example, a taxpayer may have a lower-income year after retirement and before required distributions become larger. That period may be worth analyzing.
The planning process can compare several years rather than treating the conversion as an isolated transaction.
Conclusion
A convert pretax to Roth strategy is a tax planning decision, not simply an investment decision.
The right analysis can include current and projected income, tax brackets, retirement timing, account balances, charitable goals, estate planning, and other financial events.
For some individuals, partial conversions across multiple years may warrant consideration. For others, the current tax cost may outweigh the potential future benefits.
Because the tax consequences can be significant, Roth conversion decisions should be evaluated using current tax rules and the taxpayer's specific financial circumstances.
Frequently Asked Questions About Converting Pretax Assets to Roth
What is a pretax to Roth conversion?
It generally involves moving eligible funds from a traditional pretax retirement account into a Roth account, with taxable income generally recognized on the converted amount under applicable rules.
Is a Roth conversion always beneficial?
No. The decision depends on current taxes, future income, retirement needs, account balances, and other planning considerations.
When might a Roth conversion make sense?
A conversion may warrant consideration during a lower-income year, before required distributions become larger, or when a taxpayer expects different future tax circumstances.
Can I convert only part of my pretax retirement account?
Partial conversions may be possible and are often considered as part of multi-year tax planning.
How does a Roth conversion affect my tax bracket?
The taxable amount of the conversion generally adds to income and can affect the marginal tax rate applicable to portions of your income.
Should I pay the conversion tax from retirement funds?
That depends on the circumstances. Using retirement assets to pay the tax can reduce the amount that remains invested for retirement.
Does a Roth conversion affect retirement planning?
It can. Changing the mix of pretax and Roth assets can affect future retirement income and tax planning.
Can business owners use Roth conversions as part of tax planning?
Potentially. Business owners may have years with unusually high or low income, creating planning opportunities that should be evaluated with their broader business and tax picture.
How does estate planning relate to Roth conversions?
Retirement account structure can affect beneficiary planning and future distributions, so Roth conversions may be considered alongside estate planning.
How many years should I model for a Roth conversion strategy?
There is no universal period. A multi-year projection can be useful when income, retirement timing, and other financial events are expected to change.
