When Can Paying More Tax Today Actually Be the Tax-Planning Move?

Roth conversion planning is mainly a decision about when income should be taxed.

Current tax cost

A conversion can create taxable income today to the extent required under applicable rules.

Future benefit

Qualifying Roth distributions can receive favorable future treatment under applicable requirements.

Why convert

Planning factors include current and future marginal rates, time horizon, other income, estate goals, liquidity, and expected growth.

Low-income year

A temporarily low-income year can create an opportunity to recognize conversion income at a lower marginal rate than expected later.

Not always better

A conversion can be inefficient when current rates are high, future rates are expected lower, or other tax provisions are adversely affected.

The takeaway

Roth conversion planning is a tax-rate and timing decision, not a universal rule.
