Self-directed IRAs give investors more control over what their retirement funds can purchase, but that flexibility comes with strict oversight.
The IRS allows SDIRAs to hold alternative assets such as real estate, private lending, and private equity. However, it imposes detailed rules on how those investments are structured and who can benefit from them.
The tax advantages—whether tax-deferred growth in a traditional account or tax-free growth in a Roth—exist only as long as the account stays compliant.
Understanding the core IRS rules around prohibited transactions, disqualified persons, and proper asset use is essential before making any SDIRA investment decisions.
How Does a Self-directed IRA Differ from Standard IRAs?
The main difference between an SDIRA and a standard IRA is the investment options.
SDIRAs allow you to invest in assets not necessarily traded openly in the secondary markets, such as:
- Real estate
- Precious metals
- Private equity
- Cryptocurrency
- Mineral rights
- Tax liens
This wider range of permitted investments allows an investor to diversify an SDIRA portfolio beyond run-of-the-mill stocks and bonds.
However, this wider range of choice also comes with stricter rules and regulations.
What Are You Not Allowed to Invest In with a Self-Directed IRA?
While there are many asset types available to SDIRA holders, not every asset is allowable in an SDIRA. IRS rules for Self-Directed IRAs do exclude certain investments, including:
- Life Insurance: You are not allowed to buy whole, variable, or universal life insurance products through an SDIRA (or any IRA, for that matter).
- Collectibles: This includes art, rugs, antiques, gems, stamps, alcoholic beverages, and most coins. Some specific bullion coins and precious metals meeting IRS purity standards are exceptions, but most collectible items are disallowed.
- S-Corporation Stock: IRAs are not eligible shareholders of S-corps, so SDIRAs cannot hold S-corp shares.
- Personal Residence or Property for Personal Use: You cannot buy a home through your IRA and live in it, rent it to family, or use it as a vacation property. Any personal benefit makes the investment prohibited.
- Partnerships or Deals Involving Disqualified Persons: You cannot structure investments that directly or indirectly benefit you, your spouse, lineal family (parents, grandparents, children, grandchildren), or service providers to the IRA.
Who Are Disqualified Persons?
In addition to investments, the IRS also disqualifies certain individuals from doing business with an IRA. According to the IRS, disqualified persons include:
- You (IRA owner)
- Your spouse
- Your children, grandchildren (lineal descendants), and their spouses
- Your parents, grandparents (lineal ascendants)
- Entities you control 50% or more
- Fiduciaries (custodian, advisor, appraiser providing services to your IRA)
Siblings, aunts, uncles, and cousins are not disqualified, meaning you can partner with them legally for investments.
Who is Eligible for a Self-Directed IRA?
Self-directed IRA (SDIRA) eligibility follows the same IRS rules that apply to Traditional and Roth IRAs. The “self-directed” part only expands your investment options — it does not change contribution or income rules.
There is no age limit for contributing to a Traditional SDIRA as long as you have earned income. The SECURE Act removed the old age-70½ cutoff, allowing contributions at any age if wages or self-employment income are present. You can also open or fund an SDIRA at any age through rollovers or transfers from other retirement accounts.
Annual Contribution Limits (2025–2026)
For both Traditional and Roth SDIRAs, annual contribution limits are:
- $7,000 per year if you are under age 50
- $8,000 per year if you are age 50 or older (includes catch-up contribution)
These limits apply across all IRAs combined, not per account.
Earned Income Requirement
You must have taxable compensation (wages, salary, or self-employment income) to make contributions. Investment income, rental income, and retirement distributions do not qualify.
Roth SDIRA Income Limits
Roth IRAs have income eligibility restrictions based on Modified Adjusted Gross Income (MAGI):
Single Filers
- Full contribution allowed below $153,000
- Phased out between $153,000–$168,000
- Not eligible above $168,000
Married Filing Jointly
- Full contribution allowed below $242,000
- Phased out between $242,000–$252,000
- Not eligible above $252,000
If income exceeds the limits, direct Roth contributions are not allowed, though rollover strategies may still be possible.
Top 5 IRS Rules for Self-Directed IRAs
After more than 20 years in alternative investing and over $1.4 billion in real estate transactions, one pattern is clear: Compliance is an essential part of long-term success.
Self-directed IRAs offer powerful tax advantages, but those benefits only exist if you operate within IRS boundaries.
Here are the five IRS rules that form the foundation of SDIRA compliance:
1. Prohibited Transaction Rule
A prohibited transaction occurs when your IRA is used in a way that directly or indirectly benefits you or another disqualified person. This is commonly called self-dealing, and it often happens unintentionally when investors treat IRA assets like personal investments instead of retirement assets.
Some common infractions include:
- Buying a vacation home for family use
- Lending IRA money to your business
- Leasing SDIRA property to yourself below market rate
- Investing in a company where you or your spouse owns 50%+
Penalty: If a prohibited transaction occurs, the IRA loses its tax-exempt status as of the first day of the year in which the transaction occurred. The entire account balance is taxable, and if you’re under age 59½, a 10% early withdrawal penalty applies to the entire balance.
2. Contribution Restrictions
An SDIRA follows the same rules as Traditional and Roth IRAs regarding contribution amounts and timing. Unlike a standard IRA, however, you must process all contributions and required minimum distributions through your SDIRA custodian.
You can’t bypass the custodian by sending money directly into or out of an IRA-owned LLC bank account.
As of 2026, RMDs must begin at age 73 for Traditional IRAs (the age increased from 72 under the SECURE 2.0 Act). The RMD age is scheduled to increase to 75 in 2033. Roth IRAs do not require RMDs during the owner’s lifetime.
3. Reporting Requirements
The IRS requires the owner of an SDIRA to complete and submit the following three forms:
- Form 990-T: Used for filing any potential Unrelated Business Income Tax (UBIT) or Unrelated Debt-Financed Income (UDFI). Your SDIRA must file this if it owes UBIT or UDFI taxes.
- Form 5498: Issued by your custodian and reports the fair market value of the SDIRA as well as a record of the prior year’s contributions. You receive this for your records; your custodian files it with the IRS.
- Form 1099-R: This reports any distributions you receive from the SDIRA. Your custodian will issue this when you take distributions.
You’re required to file even if no tax is due. Your custodian handles most forms, but monitors for accuracy.
4. Using Your SDIRA as Credit
You cannot use an SDIRA to apply for a line of credit, including a basic credit card. Applying for credit involves making a legally binding promise that you will make good on repayment obligations. The IRS prohibits an SDIRA from engaging in this practice.
Exception: Non-recourse loans are permitted for SDIRA real estate investments. These are loans in which the lender’s only recourse in the event of default is the property itself. You have no personal liability. However, income generated from debt-financed property is subject to UDFI tax (see below).
5. Tax Considerations (UBIT/UDFI)
While both a Traditional IRA and a Roth IRA provide tax shelter while funds remain in the account, this is not always the case with an SDIRA. More specifically, there are 2 possible (though uncommon) situations when taxes are owed before a withdrawal from the plan.
Unrelated Business Income Tax (UBIT)
This is a tax imposed on SDIRAs that earn income from an active trade or business. For example, if your SDIRA owns an operating business (not just passive investments), income from that business may be subject to UBIT at trust tax rates.
Unrelated Debt-Financed Income (UDFI)
UDFI is a tax on income earned from leveraged funds (i.e., borrowed money). This commonly applies when an SDIRA uses a non-recourse loan to purchase real estate. The portion of income attributable to debt financing is subject to UDFI tax.
Example: If your SDIRA purchases a $300,000 rental property with $100,000 in IRA funds and a $200,000 non-recourse loan (67% debt-financed), then 67% of the net rental income would be subject to UDFI tax.
Most SDIRA investors never trigger these. Passive rentals (no debt), land holds, and storage units stay tax-deferred/-free until distribution.
How to Avoid Penalties on Your SDIRA
Avoiding penalties in a self-directed IRA comes down to one principle: never allow personal benefit, improper transactions, or rule violations to touch the account.
Every investment decision must be structured so the IRA acts as a separate entity, expenses and income flow only through the IRA, and no disqualified persons are involved.
Self-directed IRAs offer powerful diversification and tax advantages, but those benefits remain intact only when compliance is integrated into the investment strategy.
A single prohibited transaction can collapse the account’s tax protection and trigger immediate taxes and penalties. Work with experienced custodians and tax professionals who understand alternative assets, document every transaction carefully, and consistently follow the five core IRS rules.
FAQs
What makes a Self-Directed IRA different from a Traditional or Roth IRA?
SDIRAs use the same tax structure (Traditional tax-deferred or Roth tax-free), but allow broader investments, such as real estate, precious metals, and private equity, that standard IRA custodians won’t handle.
Can I buy life insurance or my personal residence in an SDIRA?
No. Life insurance contracts and personal-use property (your home, vacation home, or rentals benefiting you directly) are prohibited investments that trigger IRS violations.
Who counts as a disqualified person for SDIRA transactions?
Disqualified persons include you, your spouse, lineal ascendants/descendants (parents, children, grandparents, grandchildren), and their spouses, entities you control 50%+, and IRA fiduciaries. Siblings, aunts, uncles, and cousins are not disqualified persons.
What happens if I commit a prohibited transaction?
The entire SDIRA loses tax-exempt status as of January 1 of that year. The full account value becomes immediately taxable, plus a 10% early withdrawal penalty if you’re under 59½.
When does an SDIRA owe UDFI tax on real estate?
UDFI taxes the debt-financed portion of leveraged property income/gains. Example: $300K property with $200K non-recourse loan = 67% of rental profits taxed annually at trust rates.
Can my SDIRA take out loans for real estate purchases?
Yes, but only non-recourse loans where the property is sole collateral. No personal guarantees allowed. Personal guarantees count as prohibited transactions.
