Creative tax planning is worth pursuing. But there’s a point where creativity starts working against you, and this is one of those situations. If you’re considering making a private loan from your Roth IRA, the structure might look elegant on paper. In practice, it raises enough red flags that the IRS would have a field day with it.
Here’s what’s actually going on with this type of arrangement, and why the risk profile looks very different from the potential reward.
Start With the Risk-Reward Math
Before getting into the technical problems, it’s worth stepping back and looking at what you’re actually trying to earn. A $250,000 loan at 8% over three years generates roughly $60,000 in total interest. That sounds meaningful until you start accounting for attorney fees to structure the loan, CPA fees to review it, ongoing compliance costs, and the legal costs of defending it if the IRS ever questions it.
Those fees stack up quickly. And the downside scenario here isn’t just losing some of that interest. If the IRS determines this is a prohibited transaction, they can disqualify the entire Roth IRA. You’d owe taxes and penalties on the full account value. The reward is capped. The downside is not.
The Prohibited Transaction Problem
IRAs come with prohibited transaction rules, and they’re written broadly on purpose. The government is already giving you the tax benefit of a Roth IRA. The rules exist to prevent people from gaming that benefit in ways that create personal advantages outside of the account.
One of the clearest restrictions is self-dealing. You cannot use an IRA to loan money to someone in a way that benefits you. Family members are explicitly off-limits. A close colleague sits in a grayer area, but it’s not a comfortable one. The IRS could reasonably argue that lending money to someone you work with creates indirect business benefits for you, and that the transaction isn’t truly arm’s length.
If you did move forward, you would need an outside party to structure the note entirely. You couldn’t do it yourself without raising the appearance of self-dealing, which means attorney fees from the start.
Why the Split Rate Structure Doesn’t Work
The idea of charging 12% on the Roth portion and 5.3% on the non-qualified portion, blending to an 8% overall rate, is creative. The instinct behind it is correct: you want high-growth assets in the Roth and lower-return assets in taxable accounts. That’s sound tax thinking in general.
The problem is that you have the same lender, the same borrower, and the same collateral on both sides of this transaction. If the IRS asks why you charged more than double the interest rate on the Roth portion versus the traditional IRA portion, and the only honest answer is that you wanted more earnings in the tax-free account, that answer is not going to hold up. The risk profile of both loans is identical. There is no legitimate basis for the rate difference, and that’s exactly what the IRS is trained to look for.
A Word on Self-Directed IRAs Generally
This situation is a good reminder to be careful with self-directed IRAs in general. The ability to make loans, buy real estate, or use checkbook IRA structures comes with an enormous amount of rules, reporting requirements, and compliance obligations. The fees alone, from setup through annual reporting, can erode returns significantly.
There are cases where a self-directed IRA makes sense for real estate investing, but they require a dedicated team of professionals who understand the structure deeply. Even something as small as reimbursing yourself for paint you bought for a rental property held inside a self-directed IRA could blow up the entire account if it isn’t handled correctly.
The juice has to be worth the squeeze. In most cases at this loan size, it isn’t.
The Bigger Principle
Aggressive tax planning is worth pursuing when the math works and the structure holds up to scrutiny. This one doesn’t clear either bar. The potential savings are modest, the fees are real, and the downside exposure is severe. When a strategy sounds like it might work but requires a lot of creative explaining to defend, that’s usually a sign to slow down.
If you’re exploring self-directed IRA strategies, work with an attorney who specializes in them before moving forward. And if a professional reviews this structure and tells you it looks fine, it’s worth getting a second opinion.
