SDIRA LLC Structure Guide: Checkbook Control for Real Estate Investors

An SDIRA LLC — commonly called a Checkbook IRA — is a legal structure where your Self-Directed IRA owns a single-member LLC, and you serve as the non-compensated manager of that LLC. This gives you direct checkbook access to IRA funds, allowing you to write checks, sign real estate contracts, and close deals without waiting for custodian approval for each transaction.

The IRS recognized this structure through Swanson v. Commissioner (1996) and subsequent private letter rulings. The key ruling: an IRA's investment in an LLC is not a prohibited transaction as long as the IRA owner does not personally benefit from the LLC (beyond the IRA's investment return).

Speed Advantage: Traditional custodian-directed SDIRAs take 3-10 business days to process purchase instructions. A Checkbook IRA lets you write a check at a real estate closing the same day — critical in competitive markets where sellers won't wait two weeks for IRA paperwork.

The formation process involves 5 sequential steps:

1. Choose a Checkbook IRA provider: IRA Financial Group ($360/yr), Broad Financial ($595 one-time + $100/yr), or IRAR Trust ($395/yr). These providers handle IRA custodianship AND LLC formation.
2. Form the LLC: The provider creates a single-member LLC in your chosen state with the operating agreement specifying your SDIRA as the sole member. Formation takes 1-3 weeks depending on state processing times.
3. Open an LLC bank account: The LLC gets its own checking account at a standard bank (Chase, Wells Fargo, etc.). This is your "checkbook" — all real estate transactions flow through this account.
4. Fund the IRA → LLC: Your SDIRA custodian transfers funds to the LLC's bank account as a capital contribution. This is not a distribution — it's an IRA investment in its own LLC.
5. Invest: As LLC manager, you now have full authority to purchase real estate, pay expenses, collect rent, and manage the investment — all from the LLC checking account.

Total Setup Cost: $595-$2,000 depending on provider and state. Ongoing annual cost: $360-$595/year (vs. $1,000-$2,000/year with per-transaction custodians).

The state where you form your LLC matters — filing fees, annual reports, and franchise taxes vary dramatically:

State	Formation Fee	Annual Report	Notes
Wyoming	$100	$60/yr	Most popular for IRA LLCs — no state income tax, strong asset protection
New Mexico	$0	$0	Cheapest option — no filing fee, no annual report required
Delaware	$90	$300/yr	Traditional choice for LLCs but higher ongoing costs
Nevada	$425	$150/yr	Strong privacy laws but expensive formation
Florida	$125	$138.75/yr	Good if you invest in FL real estate

Recommendation: Wyoming or New Mexico for most investors. Wyoming offers the best balance of low cost ($160 total first year), no state income tax, strong charging order protection, and broad acceptance by banks.

Having checkbook control means you bear full personal responsibility for avoiding prohibited transactions. There's no custodian to reject a bad transaction — you write the check, you own the consequence.

Mandatory Compliance Practices:

• Never mix personal funds with LLC funds — the LLC bank account is ONLY for IRA investments
• Never pay yourself management fees, salaries, or reimbursements from the LLC
• Keep the LLC operating agreement current and properly signed
• Maintain separate records for each property the LLC holds
• File IRS Form 990-T if the LLC has UBIT income (debt-financed property)
• Report all transactions to your SDIRA custodian for annual IRS reporting (Forms 5498, 1099-R)
• Never co-mingle investments — each property should have documentation tying it to the IRA-owned LLC

Annual Compliance Cost: Budget $500-$1,500/year for LLC maintenance (state filing), tax preparation (Form 990-T if applicable), and an annual compliance review with an SDIRA-specialized CPA.
