Converting cash is always simpler. If you have a choice, convert cash first. In-kind conversions are worth the complexity when the asset is difficult to liquidate, actively producing returns, or expected to appreciate significantly, making the tax cost of conversion worth paying now rather than later.
Valuation
Because the IRS taxes the converted amount at its fair market value, every in-kind conversion requires an independent valuation before the transaction can be processed. Acceptable methods vary by asset type:
- Real estate: A formal appraisal from a licensed professional
- Promissory notes: Outstanding principal balance plus any accrued and unpaid interest
- Private placements and other assets: Seek guidance from a qualified advisor on appropriate documentation of value
The valuation must be current; obtain it close to the conversion date, not months in advance. Retain all valuation documentation with your plan records.
Re-titling for IRA conversions
For an IRA, the asset must be re-titled to reflect the Roth IRA as the new owning account. Ownership documentation (a deed, note assignment, or subscription agreement) must be prepared by the account holder and submitted to IRA Resources along with the conversion request. IRA Resources records the movement on the custodial side; the account holder is responsible for producing the updated title documents.
No re-titling for Solo 401(k) conversions
For a Solo 401(k) in-plan Roth rollover, no re-titling is required. Plan assets are always titled in the name of the plan itself, with no reference to the underlying participant sub-account. The conversion is reflected in your internal plan records only.
Converting an asset fractionally over time
It is technically possible to convert a large asset in portions across multiple tax years, converting a percentage of the value each year to manage the annual tax impact. In practice, this approach is rarely worth pursuing. It requires fresh valuations at each conversion event, meticulous records tracking ownership percentage by account, and careful allocation of all income and expenses between the Traditional and Roth accounts for as long as the split persists. The administrative burden and risk of error are significant. This is not a DIY process, and should be executed with the guidance of a skilled tax or legal advisor.
Converting an asset in its entirety in a single transaction is almost always the cleaner path. If the full tax cost is too large to absorb in one year, consider converting a different asset or converting cash rather than fractionalizing a single holding.
Frequently Asked Questions
Can I convert a rental property in-kind?
Yes. Real estate is one of the more common in-kind conversion assets. A formal appraisal is required to establish the taxable value. For an IRA conversion, the deed must be updated to reflect the Roth IRA entity as the new owning account. For a Solo 401(k), only internal recordkeeping changes are needed.
What if the asset has appreciated significantly since I acquired it?
That appreciation is factored into the taxable value at conversion. If the asset has grown substantially, the tax cost of converting will be higher, but so will the future tax-free benefit if the asset continues to grow inside the Roth account. This is precisely the analysis to work through with your tax advisor before initiating the conversion.
Do I need a new appraisal if I already had one recently?
Possibly not, depending on how recent it is and your custodian's requirements. For IRA conversions, IRA Resources will advise on acceptable valuation timing. As a general rule, a valuation less than 60 days old is reliably acceptable.
