How to Buy Tax Liens in a Self-Directed IRA: The Complete Setup Guide
About this article: “Marcus” is TaxLienSimple's educational narrator. First-person stories and dollar examples are illustrative scenarios written to explain real tax-sale concepts, they are not the personal trading history of a specific investor. Rate and legal information is sourced separately to official statutes and government records (see About and each guide's citations).
TL;DR
- →A self-directed IRA (SDIRA) lets you invest in alternative assets like tax lien certificates - something a regular IRA or 401(k) won't allow.
- →Only a handful of custodians support tax liens; popular options include Directed IRA, Equity Trust, and IRA Resources.
- →Prohibited transactions are the biggest risk: no self-dealing, no borrowing from the IRA, no involving disqualified persons (you, spouse, lineal descendants).
- →Annual custodian fees typically run $300-$500/year, plus transaction fees per investment; UBIT can apply if you use leverage post-foreclosure.

A narrated walkthrough: find tax liens by county, read the Research Score, risk flags and sources, set your maximum bid and save a Deal Radar.
Read the transcript
If you came here for tax liens, start in Property Research and choose Tax Lien.
Liens without a set sale date sit under Timing not assigned yet. That includes over the counter liens you can buy now, with no auction.
Pick a state and a county. I'll use Maricopa County, Arizona.
Tick Mapped only to see each lien on the map, and switch to aerial imagery to look at the property from above.
Open a lien to see the full research.
The Research Score grades it from A to D, out of one hundred, and shows where the points come from.
Estimated value and confidence gives you a value range, and tells you how far to trust it. It's a starting point, not an appraisal.
Risk flags come up before you buy: whether it's still available, liens that may survive, and a source that may be out of date. Open one to see what to check.
The due diligence checklist shows the lien to value ratio and the back taxes, and what you still need to verify yourself.
Sources and freshness links every fact back to the county's own record.
Then calculate your maximum bid. You get a comfortable range, a caution range, and the price where you should stop.
Back in Research, mark it as a bid candidate, and add private notes that only you can see.
Save your search as a Deal Radar, and new matches come to you by email.
That's tax liens: from a county to a lien worth buying, with every fact sourced to the county.
Why Your Regular IRA Can't Buy Tax Liens
Your regular IRA at Fidelity, Vanguard, or Schwab only lets you buy stocks, bonds, mutual funds, and ETFs. Tax lien certificates, real estate, and private placements are alternative investments that mainstream custodians block because they're illiquid and hard to value. A self-directed IRA removes that restriction using the same Traditional or Roth wrapper, but with a custodian specialized in non-traditional assets. You make every investment decision; the custodian holds the asset and files IRS paperwork. The payoff: interest income from redeemed liens grows tax-deferred (Traditional) or tax-free (Roth), which compounds meaningfully over 10-20 years. The custodian gives no investment advice and vets no deals - you are the fund manager.
Which Custodians Allow Tax Lien Investing
Not every SDIRA custodian handles tax liens. For a small portfolio ($10,000-$25,000), lower-fee custodians like IRA Resources or New Direction keep costs manageable; for a serious portfolio ($50,000+), Directed IRA or Equity Trust offer faster processing and a checkbook-IRA option. A checkbook IRA (a self-directed IRA LLC) lets you write checks directly from an LLC bank account without waiting for custodian approval on each transaction - faster for active investors, but with no custodian gatekeeping your compliance, so a stray personal payment can trigger a prohibited transaction.
| Custodian | Annual Fee | Checkbook IRA? | Notes |
|---|---|---|---|
| Directed IRA | ~$360/yr | Yes | Strong tax lien support |
| Equity Trust | ~$349-$499/yr | Yes | One of the largest SDIRA custodians |
| IRA Resources | ~$295-$395/yr | No | Lower fees; good for smaller portfolios |
| The Entrust Group | ~$379/yr | No | Long-established, broad support |
| New Direction Trust | ~$295/yr | Yes | Competitive fees; checkbook option |

Funding deals: cash, partners, IRA, and private lending
Where the money comes from determines how much upside you keep. Put every partner or lending term in writing before funds move.
The Setup Process and a $5,000 Example
The sequence: open the SDIRA (3-10 business days, needs ID, SSN, existing statements); fund it via direct contribution ($7,000/yr, or $8,000 if 50+), an IRA rollover, or a 401(k) rollover from a former employer - most serious investors roll over because $7,000/year won't build a portfolio; submit a direction-of-investment form when you find a lien; and critically, register the certificate in the IRA's name, not yours, in a format like Custodian FBO [Your Name] IRA - personal registration can be treated as a distribution. Example: Maria rolls $50,000 from Vanguard to Directed IRA, buys a $5,000 Polk County (Florida) certificate at 18%, and 14 months later the owner redeems, sending $5,000 principal plus $1,050 interest back to the IRA - grown tax-deferred, ready to reinvest.
Rules You Cannot Break: Prohibited Transactions and UBIT
Under IRC Section 4975, a prohibited transaction occurs when you or a disqualified person (you, your spouse, parents, grandparents, children, grandchildren, or an entity they own 50%+ of) benefits personally from an IRA asset, transacts with the IRA, or uses it as loan collateral. Break the rules and the entire IRA can be disqualified - the full balance becomes immediately taxable plus a 10% penalty if you're under 59 1/2. Self-dealing is subtle: if your IRA forecloses and your own construction company bills the IRA for repairs, that's prohibited - you must hire an unrelated contractor. Separately, UBIT (Unrelated Business Income Tax) applies mainly when you use leverage: if your IRA obtains a mortgage or non-recourse loan on a foreclosed property, the leveraged income may be taxed. Avoid UBIT by not using leverage inside the IRA.
| Scenario | Allowed? | Why |
|---|---|---|
| Buy lien, owner redeems, interest returns to IRA | Yes | Standard investment activity |
| Foreclose, IRA rents property to a third party | Yes | Arm's-length rental |
| Foreclose, then you move into the property | No | Personal use of IRA asset |
| Foreclose, rent it to your daughter | No | Disqualified person |
| You personally pay the property taxes | No | Commingled personal funds |
| Use IRA as collateral for a personal loan | No | Pledging IRA as security |
Frequently Asked Questions
Can I use my existing Fidelity or Vanguard IRA to buy tax liens?↓
No. Mainstream custodians don't allow alternative investments like tax lien certificates. You must roll over funds to a self-directed IRA custodian that explicitly supports tax liens.
How much does it cost to maintain a self-directed IRA for tax liens?↓
Expect $300-$500 per year in custodian fees plus per-transaction fees ($25-$100 per direction). Checkbook IRA LLCs have higher setup costs ($1,000-$2,500) but lower per-transaction fees for active investors.
Can I use a Roth IRA to buy tax liens?↓
Yes, and it's often better. Interest in a Roth SDIRA grows tax-free and qualified withdrawals are tax-free. The trade-off is that Roth contributions are after-tax, and income limits may restrict eligibility.
Can my IRA foreclose on a tax lien?↓
Yes, but the foreclosure must be paid for with IRA funds, not personal funds. All legal fees, filing, and publication costs come from the IRA, and any property acquired is owned by the IRA, not you personally.
What is a disqualified person in an SDIRA?↓
You, your spouse, your lineal ascendants (parents, grandparents) and descendants (children, grandchildren), and any entity they own 50% or more of. The IRA cannot transact with these parties.
