How to determine IRS Form 8606 Line 6 “value” for Roth Conversion

In 2018, I did my first Roth conversion. Completing IRS Form 8606 on the 2018 tax forms was relatively easy. Line 6 was the total of all my non-Roth annuity contract accumulation values, less the annuity I was converting. I only received Fair Market Value (FMV) letters on 4 of my 7 annuities, but virtually every one was identical to my latest contract anniversary accumulation value, which also matched my end-of-year annuity value. Thus, no controversy. The annuity being converted to a Roth was 101.6% of my contract accumulation value on the 1099-R form, which the company explained as accounting for the additional value of the lifetime income rider (which I have on all 7 annuities).

In 2019, I did my second Roth conversion. In this case, the (same) life insurance company sent the 1099-R and the annuity was 103.0% of my contract accumulation value. No problem, not worth arguing the slight inconsistency. However, as I received the same 4 of 7 annuity year end FMV letters, three of these were again identical to the contract accumulation value, but one (Great American) suddenly had my FMV at 123.6% above contract accumulation value. This was in the same year that my contract lost 0.5% value (due to zero index gain and 0.5% cost of the lifetime rider deducted). I did send the paperwork in for starting the annuity late in 2020, but fail to see how this suddenly makes the annuity worth 24% more than 2018. I contacted Great American and they said that the numbers were correct, but refused to provide any detail on how this was calculated or why the sudden change between 2018 and 2019. I said I used to be an engineer and wanted to see their formula, tables, or whatever, that the math did not scare me. No luck.

Note that I have yet to take my first annuity payment from any contracts, and have not had any Roth or non-Roth IRA contributions for several years since retiring, so do not receive the IRS Form 5498’s from any of the companies. Neither the IRS publication 590 or Form 8606 instructions help in determining the definition of “value”. There is no mention of FMV, and to me it is only worth its value today, which is contract accumulation value (ignoring the fact that the contracts all still have large surrender charges).

Q1: Is the “value” referenced in IRS form 8606 contract accumulation value or FMV? FMV is so arbitrary between companies. Since no Form 5498’s are generated and sent to the IRS, does the FMV letter actually get put into a database anywhere that the IRS will challenge my Line 6 totals, which are accurate from my annual annuity documentation?

Q2: My second question is how a lifetime rider payment is calculated for IRS FMV purposes. Does the IRS give life insurance companies specific guidance? Because it is certainly not applied similarly in generating the FMV letters (for those that even bother to send them out in January).

In the end, the IRS will get their money anyway in paying for the Roth conversions or by paying taxes on non-Roth income. Using FMV instead of cumulative contract accumulation values front-end loads the payment of taxes slightly earlier, as the percentage of the basis is slightly smaller (if indeed I should use FMV instead of contract accumulation value).

It makes sence to me that the Roth conversion value uses FMV, as the IRS only gets one shot at tax money on this account, but FMV on line 6 just makes calculations ugly with vastly different calculations by different annuity companies and some never reporting FMV at all.

I can find nothing on the internet (or Ed Slott blogs) specifically addressing this. The FMV letter from Jan 31, from the companies that do send it out, just seems so unofficial that I question if the IRS uses it for anything, although it states that the IRS receives the same letter.

Thanks…sorry for the long rant, but I am so confused and this is probably the best website to clear this up..



  • This entire subject is so complex even the IRS seems content to leave a number of issues hanging. The insurance industry seems to do what they wish and there is no consistency from one to another. Until an IRA annuity is annuitized it must be treated as an “individual contract” for year end valuation purposes, and companies should be doing the calculation and reporting it to the IRA owner and the IRS on Form 5498. Some do not for “individual contracts”, and yet some do for annuitized contracts where as far as I know they are not authorized to produce a present value calculation.
  • Many IRA owners are forced to improvise to arrive at the Box 6 (Form 8606) amount, and it appears the IRS does not contest such amounts. 
  • The proper FMV for conversions is higher than for year end RMD purposes since 3 exclusions allowed in the IRS RMD Regs are not allowed when determining the conversion FMV. At least the IRS Regs include specific methods for determining this. See IRS Reg 1.408A-4, QA 14. There are 3 complex methods and obviously insurance companies do not wish to divulge or discuss which method they elected to use, since that would trigger a never ending series of questions. Will they at least provide you with the calculated result before you convert?  They should be required to, particularly now that you cannot recharacterize conversions.
  • IRS Reg 1.401(a)(9)-6 QA 12 describes FMV determination for individual contracts (not annuitized) for RMD purposes. Again, highly complex and the IRS is apparently willing to defer to the insurance companies with respect to their accuracy or what info they will provide their clients.
  • Apparently, this is too complex to reduce for IRS Pub purposes or 8606 Inst. Surely, the IRS has considered the task and so far has opted not to try OR to reduce complexity in order to be able to consolidate the rules in Pub format. Annuities in IRAs were slow to catch on so there probably has not been much demand to address these problems. In the meantime, you probably will not have full control of the implications to convert.
  • Another variable is when new mortality tables will be applied by the insurance companies in their calculations.

I expect this helps explain why the insurance company will not provide their “formula” for their FMV results. Since posting my question, I was “educated” by the only life insurance company that did NOT send out a Jan. 31 FMV letter to me (on three of my contracts), that THEY ONLY send these out when I reach the age that RMD’s are required (I am 60). They told me that this is the only thing that the IRS uses FMV’s for.  Not sure why the other four companies thus send them, except that the rules are obviously not fully understood. One of the other companies said that their FMV’s would never differ from the contract accumulation value, while another also said that their Roth conversion value would never exceed the contract accumulation value. Thanks for the comments. It eliminates my trepidation in submitting this years tax forms (and latest tax conversion).
