§1.408A-4. Converting amounts to Roth IRAs.

26 C.F.R. § 1.408A-4

This section sets forth the following questions and answers that provide rules applicable to Roth IRA conversions:

Q-1. Can an individual convert an amount in his or her traditional IRA to a Roth IRA?

A-1. (a) Yes. An amount in a traditional IRA may be converted to an amount in a Roth IRA if two requirements are satisfied. First, the IRA owner must satisfy the modified AGI limitation described in A-2(a) of this section and, if married, the joint filing requirement described in A-2(b) of this section. Second, the amount contributed to the Roth IRA must satisfy the definition of a qualified rollover contribution in section 408A(e) (i.e., it must satisfy the requirements for a rollover contribution as defined in section 408(d)(3), except that the one-rollover-per-year limitation in section 408(d)(3)(B) does not apply).

(b)
An amount can be converted by any of three methods—
(1)
An amount distributed from a traditional IRA is contributed (rolled over) to a Roth IRA within the 60-day period described in section 408(d)(3)(A)(i);
(2)
An amount in a traditional IRA is transferred in a trustee-to-trustee transfer from the trustee of the traditional IRA to the trustee of the Roth IRA; or
(3)
An amount in a traditional IRA is transferred to a Roth IRA maintained by the same trustee. For purposes of sections 408 and 408A, redesignating a traditional IRA as a Roth IRA is treated as a transfer of the entire account balance from a traditional IRA to a Roth IRA.
(c)
Any converted amount is treated as a distribution from the traditional IRA and a qualified rollover contribution to the Roth IRA for purposes of section 408 and section 408A, even if the conversion is accomplished by means of a trustee-to-trustee transfer or a transfer between IRAs of the same trustee.
(d)
A transaction that is treated as a failed conversion under § 1.408A-5 A-9(a)(1) is not a conversion.

Q-2. What are the modified AGI limitation and joint filing requirements for conversions?

A-2. (a) An individual with modified AGI in excess of $100,000 for a taxable year is not permitted to convert an amount to a Roth IRA during that taxable year. This $100,000 limitation applies to the taxable year that the funds are paid from the traditional IRA, rather than the year they are contributed to the Roth IRA.

(b)
If the individual is married, he or she is permitted to convert an amount to a Roth IRA during a taxable year only if the individual and the individual's spouse file a joint return for the taxable year that the funds are paid from the traditional IRA. In this case, the modified AGI subject to the $100,000 limit is the modified AGI derived from the joint return using the couple's combined income. The only exception to this joint filing requirement is for an individual who has lived apart from his or her spouse for the entire taxable year. If the married individual has lived apart from his or her spouse for the entire taxable year, then such individual can treat himself or herself as not married for purposes of this paragraph, file a separate return and be subject to the $100,000 limit on his or her separate modified AGI. In all other cases, a married individual filing a separate return is not permitted to convert an amount to a Roth IRA, regardless of the individual's modified AGI.

Q-3. Is a remedy available to an individual who makes a failed conversion?

A-3. (a) Yes. See § 1.408A-5 for rules permitting a failed conversion amount to be recharacterized as a contribution to a traditional IRA. If the requirements in § 1.408A-5 are satisfied, the failed conversion amount will be treated as having been contributed to the traditional IRA and not to the Roth IRA.

(b)
If the contribution is not recharacterized in accordance with § 1.408A-5, the contribution will be treated as a regular contribution to the Roth IRA and, thus, an excess contribution subject to the excise tax under section 4973 to the extent that it exceeds the individual's regular contribution limit. This is the result regardless of which of the three methods described in A-1(b) of this section applies to this transaction. Additionally, the distribution from the traditional IRA will not be eligible for the 4-year spread and will be subject to the additional tax under section 72(t) (unless an exception under that section applies).

Q-4. Do any special rules apply to a conversion of an amount in an individual's SEP IRA or SIMPLE IRA to a Roth IRA?

A-4. (a) An amount in an individual's SEP IRA can be converted to a Roth IRA on the same terms as an amount in any other traditional IRA.

(b)
An amount in an individual's SIMPLE IRA can be converted to a Roth IRA on the same terms as a conversion from a traditional IRA, except that an amount distributed from a SIMPLE IRA during the 2-year period described in section 72(t)(6), which begins on the date that the individual first participated in any SIMPLE IRA Plan maintained by the individual's employer, cannot be converted to a Roth IRA. Pursuant to section 408(d)(3)(G), a distribution of an amount from an individual's SIMPLE IRA during this 2-year period is not eligible to be rolled over into an IRA that is not a SIMPLE IRA and thus cannot be a qualified rollover contribution. This 2-year period of section 408(d)(3)(G) applies separately to the contributions of each of an individual's employers maintaining a SIMPLE IRA Plan.
(c)
Once an amount in a SEP IRA or SIMPLE IRA has been converted to a Roth IRA, it is treated as a contribution to a Roth IRA for all purposes. Future contributions under the SEP or under the SIMPLE IRA Plan may not be made to the Roth IRA.

Q-5. Can amounts in other kinds of retirement plans be converted to a Roth IRA?

A-5. No. Only amounts in another IRA can be converted to a Roth IRA. For example, amounts in a qualified plan or annuity plan described in section 401(a) or 403(a) cannot be converted directly to a Roth IRA. Also, amounts held in an annuity contract or account described in section 403(b) cannot be converted directly to a Roth IRA.

Q-6. Can an individual who has attained at least age 70 1/2 by the end of a calendar year convert an amount distributed from a traditional IRA during that year to a Roth IRA before receiving his or her required minimum distribution with respect to the traditional IRA for the year of the conversion?

A-6. (a) No. In order to be eligible for a conversion, an amount first must be eligible to be rolled over. Section 408(d)(3) prohibits the rollover of a required minimum distribution. If a minimum distribution is required for a year with respect to an IRA, the first dollars distributed during that year are treated as consisting of the required minimum distribution until an amount equal to the required minimum distribution for that year has been distributed.

(b)
As provided in A-1(c) of this section, any amount converted is treated as a distribution from a traditional IRA and a rollover contribution to a Roth IRA and not as a trustee-to-trustee transfer for purposes of section 408 and section 408A. Thus, in a year for which a minimum distribution is required (including the calendar year in which the individual attains age 70 1/2), an individual may not convert the assets of an IRA (or any portion of those assets) to a Roth IRA to the extent that the required minimum distribution for the traditional IRA for the year has not been distributed.
(c)
If a required minimum distribution is contributed to a Roth IRA, it is treated as having been distributed, subject to the normal rules under section 408(d)(1) and (2), and then contributed as a regular contribution to a Roth IRA. The amount of the required minimum distribution is not a conversion contribution.

Q-7. What are the tax consequences when an amount is converted to a Roth IRA?

A-7. (a) Any amount that is converted to a Roth IRA is includible in gross income as a distribution according to the rules of section 408(d)(1) and (2) for the taxable year in which the amount is distributed or transferred from the traditional IRA. Thus, any portion of the distribution or transfer that is treated as a return of basis under section 408(d)(1) and (2) is not includible in gross income as a result of the conversion.

(b)
The 10-percent additional tax under section 72(t) generally does not apply to the taxable conversion amount. But see § 1.408A-6 A-5 for circumstances under which the taxable conversion amount would be subject to the additional tax under section 72(t).
(c)
Pursuant to section 408A(e), a conversion is not treated as a rollover for purposes of the one-rollover-per-year rule of section 408(d)(3)(B).

Q-8. Is there an exception to the income-inclusion rule described in A-7 of this section for 1998 conversions?

A-8. Yes. In the case of a distribution (including a trustee-to-trustee transfer) from a traditional IRA on or before December 31, 1998, that is converted to a Roth IRA, instead of having the entire taxable conversion amount includible in income in 1998, an individual includes in gross income for 1998 only one quarter of that amount and one quarter of that amount for each of the next 3 years. This 4-year spread also applies if the conversion amount was distributed in 1998 and contributed to the Roth IRA within the 60-day period described in section 408(d)(3)(A)(i), but after December 31, 1998. However, see § 1.408A-6 A-6 for special rules requiring acceleration of inclusion if an amount subject to the 4-year spread is distributed from the Roth IRA before 2001.

Q-9. Is the taxable conversion amount included in income for all purposes?

A-9. Except as provided below, any taxable conversion amount includible in gross income for a year as a result of the conversion (regardless of whether the individual is using a 4-year spread) is included in income for all purposes. Thus, for example, it is counted for purposes of determining the taxable portion of social security payments under section 86 and for purposes of determining the phase-out of the $25,000 exemption under section 469(i) relating to the disallowance of passive activity losses from rental real estate activities. However, as provided in § 1.408A-3 A-5, the taxable conversion amount (and any resulting change in other elements of adjusted gross income) is disregarded for purposes of determining modified AGI for section 408A.

Q-10. Can an individual who makes a 1998 conversion elect not to have the 4-year spread apply and instead have the full taxable conversion amount includible in gross income for 1998?

A-10. Yes. Instead of having the taxable conversion amount for a 1998 conversion included over 4 years as provided under A-8 of this section, an individual can elect to include the full taxable conversion amount in income for 1998. The election is made on Form 8606 and cannot be made or changed after the due date (including extensions) for filing the 1998 Federal income tax return.

Q-11. What happens when an individual who is using the 4-year spread dies, files separately, or divorces before the full taxable conversion amount has been included in gross income?

A-11. (a) If an individual who is using the 4-year spread described in A-8 of this section dies before the full taxable conversion amount has been included in gross income, then the remainder must be included in the individual's gross income for the taxable year that includes the date of death.

(b)
However, if the sole beneficiary of all the decedent's Roth IRAs is the decedent's spouse, then the spouse can elect to continue the 4-year spread. Thus, the spouse can elect to include in gross income the same amount that the decedent would have included in each of the remaining years of the 4-year period. Where the spouse makes such an election, the amount includible under the 4-year spread for the taxable year that includes the date of the decedent's death remains includible in the decedent's gross income and is reported on the decedent's final Federal income tax return. The election is made on either Form 8606 or Form 1040, in accordance with the instructions to the applicable form, for the taxable year that includes the decedent's date of death and cannot be changed after the due date (including extensions) for filing the Federal income tax return for the spouse's taxable year that includes the decedent's date of death.
(c)
If a Roth IRA owner who is using the 4-year spread and who was married in 1998 subsequently files separately or divorces before the full taxable conversion amount has been included in gross income, the remainder of the taxable conversion amount must be included in the Roth IRA owner's gross income over the remaining years in the 4-year period (unless accelerated because of distribution or death).

Q-12. Can an individual convert a traditional IRA to a Roth IRA if he or she is receiving substantially equal periodic payments within the meaning of section 72(t)(2)(A)(iv) from that traditional IRA?

A-12. Yes. Not only is the conversion amount itself not subject to the early distribution tax under section 72(t), but the conversion amount is also not treated as a distribution for purposes of determining whether a modification within the meaning of section 72(t)(4)(A) has occurred. Distributions from the Roth IRA that are part of the original series of substantially equal periodic payments will be nonqualified distributions from the Roth IRA until they meet the requirements for being a qualified distribution, described in § 1.408A-6 A-1(b). The additional 10-percent tax under section 72(t) will not apply to the extent that these nonqualified distributions are part of a series of substantially equal periodic payments. Nevertheless, to the extent that such distributions are allocable to a 1998 conversion contribution with respect to which the 4-year spread for the resultant income inclusion applies (see A-8 of this section) and are received during 1998, 1999, or 2000, the special acceleration rules of § 1.408A-6 A-6 apply. However, if the original series of substantially equal periodic payments does not continue to be distributed in substantially equal periodic payments from the Roth IRA after the conversion, the series of payments will have been modified and, if this modification occurs within 5 years of the first payment or prior to the individual becoming disabled or attaining age 59 1/2, the taxpayer will be subject to the recapture tax of section 72(t)(4)(A).

Q-13. Can a 1997 distribution from a traditional IRA be converted to a Roth IRA in 1998?

A-13. No. An amount distributed from a traditional IRA in 1997 that is contributed to a Roth IRA in 1998 would not be a conversion contribution. See A-3 of this section regarding the remedy for a failed conversion.

Q-14. What is the amount that is treated as a distribution, for purposes of determining income inclusion, when a conversion involves an annuity contract?

A-14. (a) In general—(1) Distribution of Fair Market Value Upon Conversion. Notwithstanding § 1.408-4(e), when part or all of a traditional IRA that is an individual retirement annuity described in section 408(b) is converted to a Roth IRA, for purposes of determining the amount includible in gross income as a distribution under § 1.408A-4, A-7, the amount that is treated as distributed is the fair market value of the annuity contract on the date the annuity contract is converted. Similarly, when a traditional IRA that is an individual retirement account described in section 408(a) holds an annuity contract as an account asset and the traditional IRA is converted to a Roth IRA, for purposes of determining the amount includible in gross income as a distribution under § 1.408A-4, A-7, the amount that is treated as distributed with respect to the annuity contract is the fair market value of the annuity contract on the date that the annuity contract is distributed or treated as distributed from the traditional IRA. The rules in this A-14 also apply to conversions from SIMPLE IRAs.

(2)
Annuity contract surrendered. Paragraph (a)(1) of this paragraph A-14 does not apply to a conversion of a traditional IRA to the extent the conversion is accomplished by the complete surrender of an annuity contract for its cash value and the reinvestment of the cash proceeds in a Roth IRA, but only if the surrender extinguishes all benefits and other characteristics of the contract. In such a case, the cash from the surrendered contract is the amount reinvested in the Roth IRA.
(3)
Definitions. The definitions set forth in § 1.408A-8 apply for purposes of this paragraph A-14.
(b)
Determination of fair market value—
(1)
Overview—
(i)
Use of alternative methods. This paragraph (b) sets forth methods which may be used to determine the fair market value of an individual retirement annuity for purposes of paragraph (a)(1) of this paragraph A-14. However, if, because of the unusual nature of the contract, the value determined under one of these methods does not reflect the full value of the contract, that method may not be used.
(ii)
Additional guidance. Additional guidance regarding the fair market value of an individual retirement annuity, including formulas to be used for determining fair market value, may be issued by the Commissioner in revenue rulings, notices, or other guidance published in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b)).
(2)
Gift tax method—
(i)
Cost of contract or comparable contract. If with respect to an annuity, there is a comparable contract issued by the company which sold the annuity, the fair market value of the annuity may be established by the price of the comparable contract. If the conversion occurs soon after the annuity was sold, the comparable contract may be the annuity itself, and thus, the fair market value of the annuity may be established through the sale of the particular contract by the company (that is, the actual premiums paid for such contract).
(ii)
Use of reserves where no comparable contract available. If with respect to an annuity, there is no comparable contract available in order to make the comparison described in paragraph (b)(2)(i) of this paragraph A-14, the fair market value may be established through an approximation that is based on the interpolated terminal reserve at the date of the conversion, plus the proportionate part of the gross premium last paid before the date of the conversion which covers the period extending beyond that date.
(3)
Accumulation method. As an alternative to the gift tax method described in paragraph (b)(2) of this paragraph A-14, this paragraph (b)(3) provides a method that may be used for an annuity contract which has not been annuitized. The fair market value of such an annuity contract is permitted to be determined using the methodology provided in § 1.401(a)(9)-6(m)(2), with the following modifications:
(i)
All front-end loads and other non-recurring charges assessed in the twelve months immediately preceding the conversion must be added to the account value.
(ii)
Future distributions are not to be assumed in the determination of the actuarial present value of additional benefits.
(iii)
The exclusions provided under § 1.401(a)(9)-6(m)(3), are not to be taken into account.
(c)
Effective/applicability date. The provisions of this paragraph A-14 are applicable to any conversion in which an annuity contract is distributed or treated as distributed from a traditional IRA on or after August 19, 2005. However, for annuity contracts distributed or treated as distributed from a traditional IRA on or before December 31, 2008, taxpayers may instead apply the valuation methods in § 1.408A-4T (as it appeared in the April 1, 2008, edition of 26 CFR part 1) and Revenue Procedure 2006-13 (2006-1 CB 315) (See § 601.601(d)(2)(ii)(b)).
