How a Discount Conversion Moves Your Old 401k Into a Roth and Cuts the Tax Bill by 60%

Jul 1, 2026 | Investing, Retirement

Here is the part nobody explained when you opened that traditional retirement account.

Every dollar you put in, you got a deduction, and that felt great. But you never actually owned that money. The IRS owns a chunk of it, and they collect when you pull it out, plus tax on everything it grew into. So you spent twenty years building a number that is partly theirs. A discount conversion is how you take it back.

Start with the simple version. You can convert almost any traditional account into a Roth. Old 401k, IRA, SEP, 403b, all of it. When you convert, you pay tax that year on the amount you move. The only one you cannot touch yet is a 401k with a company you currently work for. Leave that job and it is fair game. That is a plain conversion, and anybody can do it.

Now here is what the wealthy actually do. Instead of converting the money straight across, you move it into a self directed account and invest it into a real, improved structure that you do not own. A multifamily deal. A hedge fund. Something with restricted access. Then you hire a discount conversion appraiser, and this is the part people miss, you are not appraising the deal. You are appraising what your money is now worth to the IRS, because your access to it is locked up. Done right, that value comes back around sixty percent lower.

So say you have $2.3 million sitting in traditional accounts. After the discount, the IRS treats it as roughly $920,000. You convert that $920,000, you pay tax on $920,000, and the other $1.38 million lands in your Roth and is never taxed again. Not by you, not by your kids, not on a single dollar it earns for the rest of your life. You took the deduction going in, the growth is tax free, and the withdrawal is tax free. That is the only account on earth that does all three.

Here is where people screw it up, so pay attention.

This is not for someone with forty grand in an old IRA. It is for people with real balances they want to get out from under.

The investment has to be a legitimate structure you actually invest in and do not control. You cannot fake the illiquidity and you cannot fake the appraisal. It has to be a real discount conversion appraiser, not your buddy with a calculator.

And the biggest mistake of all is timing. The whole point is to run this in a year you already have big paper losses sitting on the table. Bonus depreciation from real estate, a heavy equipment year, business losses, whatever you have engineered. Stack those losses against the converted amount and even that $920,000 can get wiped down to almost nothing. Bolt this onto a random high income year with nothing to offset it and you just wrote yourself a fat tax check for no reason. That is dumb shit, and it is completely avoidable.

One more thing. Document everything. Lowest appraisal, the structure, the conversion, all of it. People do not lose audits for being wrong. They lose for having no paper.

The bigger picture is control. The account is just a container. What matters is which side of the ledger you actually own, the side the IRS gets to dip into later, or the side that is yours forever. A discount conversion moves money from the first to the second.

It is a tool. Like every tool, it only works when the structure underneath it is built right. Get that wrong and it is just an expensive way to feel clever.
