How a Self Directed IRA Works

A self directed IRA is a type of individual retirement account that allows the account holder to invest in a much broader range of assets than a conventional IRA at a brokerage or bank. Most retirement accounts limit investors to stocks, bonds, mutual funds, and ETFs. A self directed IRA can hold real estate, private loans, private equity, precious metals, cryptocurrency, and other alternative assets, all within the same tax advantaged structure that makes conventional IRAs valuable. Understanding how a self directed IRA works is the first step before deciding whether one belongs in your retirement strategy. For a step by step walkthrough of opening an account, see our guide on how to open a self directed IRA.

The Basic Structure of a Self Directed IRA

A self directed IRA functions like any other IRA at the structural level. Contributions are made within the annual limits set by the IRS, the account grows tax deferred in the case of a Traditional IRA or tax free in the case of a Roth IRA, and distributions are subject to the same rules governing all IRAs including the 10 percent early withdrawal penalty for distributions before age 59 and a half and Required Minimum Distributions beginning at age 73 for Traditional accounts.

The key difference is the custodian. A conventional IRA at a brokerage firm holds the account and executes trades within the limited set of securities that brokerage offers. A self directed IRA uses a specialized custodian who is authorized to hold non-traditional assets on behalf of the IRA. The custodian does not advise on investments and does not evaluate whether a deal is sound. The custodian holds the assets, processes transactions at the direction of the account holder, and handles administrative and reporting requirements. The investment decisions and due diligence are the account holder’s responsibility entirely. For a detailed breakdown of what custodians do and do not do, see our guide on what self directed IRA custodians do and do not do.

What a Self Directed IRA Can Invest In

The IRS does not define what a self directed IRA can invest in. Instead it defines what is prohibited. Everything else is permitted provided it does not run afoul of the prohibited transaction rules. In practice this means a self directed IRA can hold almost any asset that has legitimate investment value.

Real estate is the most commonly held alternative asset inside a self directed IRA. The IRA can own single family rental homes, multi family properties, commercial buildings, raw land, and other real property directly, provided the property is held purely for investment purposes with no personal use by the account holder or any disqualified person. For the complete framework on real estate investing inside an IRA, see our guide on investing in real estate with an IRA.

Private lending is another widely used strategy. The IRA acts as the lender on a private loan, collecting interest payments that flow back into the account. The IRA can originate loans secured by real estate, business assets, or other collateral, with interest rates and terms set between the IRA and the borrower. For how private lending inside an IRA works in detail, see our guide on private lending inside a self directed IRA.

Precious metals including gold, silver, platinum, and palladium meeting IRS purity standards can be held inside a self directed IRA through an approved custodian and stored at an IRS-approved depository. Cryptocurrency including Bitcoin and Ethereum can be held inside a self directed IRA through custodians who support digital asset custody. Private equity, startup investments, tax liens, and other alternative assets are also permissible in the right structures.

The assets that are definitively prohibited include collectibles such as art, rugs, antiques, stamps, coins that do not meet IRS specifications, alcoholic beverages, and certain other tangible personal property. Life insurance contracts are also prohibited inside an IRA. S corporation stock cannot be held by an IRA because an IRA is not an eligible S corporation shareholder. Outside these specific prohibitions, the range of permissible investments is very broad.

How Transactions Work Inside a Self Directed IRA

Every transaction inside a self directed IRA follows a specific process that differs meaningfully from buying a stock or ETF in a conventional brokerage account. The account holder identifies an investment opportunity, performs due diligence, and then directs the custodian to execute the transaction using IRA funds.

This direction process typically involves submitting a Buy Direction Letter or Investment Authorization Form to the custodian along with supporting documentation for the investment. The custodian reviews the paperwork for completeness and process compliance, not for investment quality. Once approved, the custodian transfers the funds from the IRA to the counterparty in the transaction, whether that is a title company closing a real estate purchase, a borrower receiving a loan, or a company receiving an equity investment.

All income generated by the investment flows back to the IRA, not to the account holder personally. Rental income from an IRA-owned property must be deposited to the IRA. Interest payments on an IRA-funded loan must be paid to the custodian on behalf of the IRA. Capital gains from the sale of an IRA asset go back into the IRA. The account holder cannot receive any personal economic benefit from an IRA investment before taking a formal distribution.

All expenses related to an IRA investment must also be paid from IRA funds. Property taxes, insurance, maintenance, and management fees on an IRA-owned property all come out of the IRA. An account holder who pays an IRA-related expense from personal funds has created a prohibited transaction regardless of intent.

The Prohibited Transaction Rules

The prohibited transaction rules are the single most important compliance framework for self directed IRA investors to understand. These rules exist to prevent the IRA and the account holder from transacting with each other in ways that would allow the account holder to receive a current personal benefit from assets that are supposed to be growing tax advantaged for retirement.

The core concept is the disqualified person. A disqualified person is someone the IRA cannot transact with. This includes the IRA owner, their spouse, their parents, their children, their grandchildren, and entities those individuals control at fifty percent or above. The IRA cannot buy property from a disqualified person, sell property to a disqualified person, lend money to a disqualified person, lease property to a disqualified person, or otherwise transact with a disqualified person in almost any way.

A prohibited transaction does not result in a penalty. It results in the entire IRA being treated as distributed on the first day of the year in which the transaction occurred, creating a significant tax liability and potential early withdrawal penalties for the entire account balance. This consequence makes understanding and avoiding prohibited transactions one of the most critical aspects of managing a self directed IRA correctly. For the complete framework on who counts as a disqualified person and what transactions are prohibited, see our guide on who is a disqualified person in a self directed IRA.

Self Directed IRA Account Types

A self directed IRA can be structured as a Traditional IRA, a Roth IRA, a SEP IRA, or a SIMPLE IRA. The self directed designation refers to the investment flexibility, not the tax treatment. The tax rules governing each account type remain the same regardless of whether the account is self directed.

A Traditional self directed IRA accepts pre-tax contributions up to the annual limit, grows tax deferred, and distributions are taxed as ordinary income. Investors who expect to be in a lower tax bracket in retirement than during their working years generally favor Traditional accounts.

A Roth self directed IRA accepts after-tax contributions, grows tax free, and qualified distributions are taken entirely tax free including all gains. For an investor who makes a private equity investment inside a Roth self directed IRA and that investment grows significantly, the entire gain can be distributed tax free in retirement. This tax free treatment on alternative asset gains is one of the most compelling reasons experienced investors choose Roth self directed IRAs specifically for higher-return alternative asset strategies.

A SEP IRA allows self-employed individuals and small business owners to contribute much larger amounts than a standard IRA, up to 25 percent of compensation or the annual SEP limit, whichever is lower. A SEP IRA can be self directed the same way a Traditional IRA can, opening the same range of alternative investment options with the higher contribution ceiling. For the complete contribution limits across all account types and ages, see our guide on self directed IRA contribution limits.

The IRA LLC Structure

Some self directed IRA investors establish a limited liability company that is owned by the IRA, commonly called a checkbook control IRA or IRA LLC. In this structure, the IRA owns the LLC, and the LLC has its own bank account. The account holder, acting as manager of the LLC, can make investments directly from the LLC checking account without going through the custodian for each transaction.

The IRA LLC structure can speed up transactions significantly, which matters in real estate deals with short closing timelines or private lending situations requiring quick funding. However, the compliance requirements for an IRA LLC are more demanding than for a standard self directed IRA, and the prohibited transaction risks are heightened because the account holder has more direct access to the funds. For the complete framework on checkbook control structures, see our guide on checkbook control IRA rules, benefits, and compliance.

What a Self Directed IRA Is Not

A self directed IRA is not a vehicle for investing in assets that generate personal benefit before retirement. It is not a way to invest in your own business or a business your family controls. It is not a way to buy property you or your family intend to use. It is not a way to hire yourself or family members to work on IRA assets and get paid for that work. Every one of these scenarios creates a prohibited transaction that disqualifies the entire account.

A self directed IRA is also not a high-risk mandatory strategy. Many investors use self directed IRAs conservatively, holding private notes secured by real estate at modest loan to value ratios as a stable income generating alternative to bonds. The fact that a self directed IRA can hold speculative assets does not mean it should. The appropriate investment strategy inside a self directed IRA depends on the same factors that govern any investment decision including risk tolerance, time horizon, and portfolio diversification objectives. For investors evaluating precious metals as a portfolio stabilizer within a self directed IRA, see our guide to the best gold IRA companies for 2026.

The tax treatment of a self directed IRA depends on whether it is structured as a Traditional or Roth account. For a complete comparison of how these two structures work and which one fits different investor profiles, see our guide on self directed IRA vs Roth IRA. For a detailed breakdown of how custodians work and what to look for when choosing one, see our guide on what is an IRA custodian.

A self directed IRA is one of the most flexible retirement vehicles available to American investors, but that flexibility comes with a responsibility that conventional IRA holders never face: the full burden of investment research, due diligence, compliance monitoring, and administrative discipline falls on the account holder rather than being shared with a brokerage or financial institution. Investors who embrace that responsibility and invest the time to understand both the opportunity and the rules consistently find the self directed structure to be a powerful addition to a long-term retirement strategy. Those who underestimate the compliance requirements or assume the custodian will catch mistakes frequently discover the consequences at great cost. The starting point for doing this well is simply learning how the structure works before making any investment, which is exactly what this guide is designed to help with.

FAQ

Can I manage my own self directed IRA investments without a financial advisor?

Yes. The self directed structure is specifically designed for investors who want to make their own investment decisions rather than delegating them to a financial advisor or letting a brokerage choose from a limited menu of securities. You are responsible for identifying investments, performing due diligence, understanding the compliance rules, and directing your custodian to execute transactions. The custodian does not advise you, and there is no requirement to use a financial advisor. Many investors who choose self directed IRAs do so precisely because they have expertise in a specific asset class, such as real estate or private lending, that they want to apply within a tax advantaged structure.

How is a self directed IRA different from a regular IRA?

The tax treatment and contribution rules are identical. The difference is the custodian and the permitted investments. A regular IRA at a brokerage holds only publicly traded securities like stocks, bonds, mutual funds, and ETFs. A self directed IRA uses a specialized custodian who can hold alternative assets including real estate, private loans, precious metals, cryptocurrency, and private equity. The self directed structure comes with more administrative responsibility for the account holder and stricter compliance requirements around prohibited transactions.

What happens if I make a prohibited transaction inside my self directed IRA?

A prohibited transaction results in the IRA being treated as fully distributed on January 1 of the year the transaction occurred. The entire account balance becomes taxable income for that year, and if the account holder is under age 59 and a half, the 10 percent early withdrawal penalty applies to the entire balance as well. This consequence applies to the full account, not just the specific asset involved in the violation. The severity of this outcome is why understanding the prohibited transaction rules before making any investment is so critical for self directed IRA investors.
