How to Work with a CPA on SDIRA Tax Reporting: 2026 Complete Checklist for Self-Directed IRA Investors

The Self-Directed IRA tax landscape is one of the most technically demanding areas in retail investment taxation. It sits at the intersection of exempt organization law (IRC §§408, 511–514), trust taxation, real estate tax rules, partnership K-1 reporting, multi-state filing obligations, and prohibited transaction rules under IRC §4975. A CPA who handles W-2 wage earners and small business owners — even an excellent one — may have zero experience with any of it.

This is not a criticism of CPAs generally. SDIRA tax reporting is simply a niche. The majority of tax professionals will never encounter a Form 990-T filing for an IRA during their careers. But when you are the investor holding a leveraged rental property, a private equity interest, or a cryptocurrency position inside a Self-Directed IRA, “my CPA has never seen this before” is an expensive problem.

This guide gives you the complete framework: how to identify a qualified SDIRA CPA, what documents to gather before your first meeting, how the annual reporting process should unfold, what questions to ask, and red flags that signal a CPA is out of their depth.

Quick Answer: SDIRA CPA Checklist at a Glance

• Not all CPAs can handle SDIRA tax reporting. Form 990-T preparation for IRAs requires specific knowledge of IRC §§511–514, ADS depreciation, UDFI calculations, multi-state exempt organization filings, and prohibited transaction rules. Confirm this experience before engaging anyone.
• Your custodian does not prepare your taxes. The IRA custodian holds the assets and may sign the Form 990-T as the filer, but the custodian does not prepare the return, calculate the UBTI, or handle state filings. That is your responsibility — typically through a CPA you hire.
• Document organization is the investor’s job. A CPA can only prepare an accurate return from accurate records. Gathering income statements, loan schedules, expense receipts, depreciation schedules, K-1s, and fair market valuations is the investor’s responsibility — not the CPA’s.
• Annual reporting is a multi-step process. It involves gathering documents, computing UBTI (including ADS depreciation and debt-financed percentage), preparing federal Form 990-T, preparing state equivalent returns, coordinating with the custodian to sign and file, and paying taxes from IRA assets.
• CPA fees for SDIRA reporting are an IRA expense. Fees paid to a CPA for SDIRA tax work related to the IRA’s investments can generally be paid from IRA assets as an investment expense — not from personal funds. Confirm treatment with your CPA.
• Start the process early. The federal Form 990-T due date for calendar-year IRAs is May 15. State filings often have the same or nearby deadlines. Gathering complex multi-asset documentation takes time. Starting in January or February avoids the crush.

Why SDIRA Tax Reporting Requires a Specialist

To understand why a specialist is necessary, it helps to understand exactly what SDIRA tax reporting involves. For an IRA holding a leveraged rental property, the annual tax work includes:

• Calculating the debt-financed percentage under IRC §514 using average acquisition indebtedness and average adjusted basis
• Computing depreciation under the Alternative Depreciation System (ADS) per IRC §168(g) — not regular MACRS used by taxable investors
• Allocating every expense (interest, property taxes, insurance, management fees, repairs) by the debt-financed percentage
• Computing net UDFI after allocable deductions and the IRC §512(b)(12) $1,000 specific deduction
• Preparing federal Form 990-T with the correct schedules
• Preparing equivalent state returns in every state where the IRA has income-producing nexus, each on its own form with its own rules
• Coordinating with the IRA custodian — who is the technical filer on the 990-T — to ensure the return is signed and filed correctly
• Ensuring the taxes are paid from IRA assets, not personal funds

For an IRA holding a private equity interest that issues a K-1, the work also involves understanding how K-1 income inside a Self-Directed IRA is treated — which box on the K-1 generates UBTI, how the UBTI siloing rule under IRC §512(a)(6) applies across multiple investments, and whether the K-1 allocates any acquisition indebtedness that would create UDFI in addition to ordinary UBTI.

None of this is covered in standard CPA continuing education. It requires deliberate specialization.

How to Find and Vet a SDIRA-Qualified CPA

There is no formal certification for SDIRA tax work. The credential to look for is experience — specifically, documented experience preparing Form 990-T returns for IRA trusts (not just for nonprofits or other tax-exempt organizations, which is a different context). Here is how to find and vet candidates:

Self-Directed IRA Bookkeeping: What Investors Should Maintain Year-Round

Good tax reporting starts with good recordkeeping — and that is the investor’s job, not the CPA’s. Here is the bookkeeping framework that makes annual tax prep efficient and accurate:

• Maintain a dedicated folder or accounting file for each IRA-held investment. For real property, this means separate folders for income, expenses, loan statements, and insurance. For partnerships, a folder for K-1s, operating agreements, and any capital account statements.
• Record every rental payment as it is received. Use a simple spreadsheet or property management software. Log the date, tenant, amount, and payment method. Reconcile monthly against the IRA custodian’s records.
• Scan and file every expense receipt immediately. The IRS requires substantiation for deductions. A repair invoice paid from IRA funds three years ago that cannot be located is a deduction that cannot be claimed. Organize receipts by property and by month.
• Track loan balances monthly. Download the lender’s monthly statement or log the opening and closing balance. This data feeds directly into the average acquisition indebtedness calculation for the debt-financed percentage.
• Maintain a running depreciation schedule. Start with the purchase price allocation (land vs. building), apply ADS depreciation in the correct year (the first year uses a mid-month convention for real property under ADS), and update it each year. This schedule should be handed to your CPA as a starting point, not rebuilt from scratch each year.
• Log any capital improvements separately from repairs. Under the IRS Repair Regulations (Treas. Reg. §1.263(a)-3), capital improvements must be capitalized and depreciated — not expensed. Keep a separate log of any expenditure over a defined threshold (many investors use $2,500 as the starting point for analysis) that might qualify as a capital improvement.

Red Flags: Signs Your CPA Is Not Qualified for SDIRA Work

Not every CPA who agrees to take on SDIRA work is qualified to do it correctly. Here are specific red flags that should prompt you to seek a second opinion or find a different preparer:

• They use MACRS depreciation instead of ADS. IRAs must use ADS under IRC §168(g). Using MACRS overstates depreciation, understates taxable income in some contexts, and creates a filing error. If your CPA’s depreciation schedule uses a 27.5-year life for residential property (the MACRS life) instead of 30 years (the ADS life), the return is incorrect.
• They are unaware of the UBTI siloing rule. Since the Tax Cuts and Jobs Act of 2017, IRC §512(a)(6) requires separate computation of UBTI from each unrelated trade or business. If your CPA nets losses from one UBTI activity against income from another on the federal Form 990-T, the return is incorrect.
• They file only the federal Form 990-T and ignore state filings. If your IRA has income-producing activity in any state that taxes UBTI, a state return must be filed. A CPA who prepares only the federal return without asking about states is missing a significant part of the obligation.
• They treat the Form 990-T the same as a nonprofit’s Form 990-T. The form is the same, but the context differs in important ways. An IRA’s 990-T involves the non-recourse loan rules, ADS depreciation, and the IRA’s trust tax status. A CPA whose only 990-T experience is with charities or educational institutions may apply nonprofit rules incorrectly to an IRA context.
• They cannot explain the debt-financed percentage calculation. This is the core calculation in all UDFI analysis. A qualified SDIRA CPA can walk you through it from memory. One who cannot is not the right person for this work.
• They suggest the IRA owner can pay the UBTI tax personally. The tax is an obligation of the IRA trust, paid from IRA assets. Paying it from personal funds could constitute a contribution (subject to annual limits) or a prohibited transaction. A CPA who suggests personal payment of IRA taxes does not understand the structure.

CPA Fees: What SDIRA Tax Work Costs and How to Pay for It

SDIRA tax reporting is more complex than standard individual tax preparation, and fees reflect that complexity. Typical fee ranges for qualified practitioners:

• Federal Form 990-T only (single leveraged property, no K-1s, one state): $800–$1,500 per year
• Federal Form 990-T plus one or two state returns: $1,200–$2,500 per year
• Complex multi-state filing with K-1 income from multiple partnerships: $2,500–$5,000+ per year
• First-year engagement (building depreciation schedules, establishing basis, reviewing prior returns): Add $500–$1,500 to the above for setup work

These fees are generally payable from IRA assets as an investment expense directly connected to the IRA’s income-producing activities. Your custodian can process a disbursement from the IRA to pay the CPA. Do not pay SDIRA-related CPA fees from personal funds if the work relates entirely to the IRA’s investments — keeping the expense inside the IRA preserves the tax-deferred treatment of those funds.

How Sophisticated Investors Structure the CPA Relationship

• Engage the CPA before you close on a new investment, not after. A qualified SDIRA CPA can review the proposed investment structure, identify any prohibited transaction risks, model the expected UBTI exposure, and advise on how to structure the acquisition to minimize state filing obligations. This pre-close review often costs $200–$500 but can save thousands in avoided errors.
• Have a mid-year check-in for complex investments. For leveraged properties or partnership interests that generate significant UBTI, a mid-year conversation with your CPA allows for estimated tax planning and ensures you are building the right documentation throughout the year rather than scrambling in April.
• Keep your CPA informed of every new investment. An investment that seems simple — a private note, a cryptocurrency position, a minority LLC interest — can have UBTI implications that are not obvious. Notify your CPA before closing, not at tax time.
• Ask your CPA to maintain a multi-year UBTI projection. The debt-financed percentage on a leveraged property changes every year as the loan amortizes. A good SDIRA CPA maintains a forward projection showing estimated UBTI and estimated tax for years 1 through 10 of a hold, updated annually. This allows you to plan liquidity reserves inside the IRA.
• Verify that the custodian and CPA are coordinating correctly on Form 990-T signing. The IRA custodian is the technical filer and must sign Form 990-T. Different custodians have different processes for this — some will sign a return prepared by your CPA; others have their own preferred preparers. Clarify this process with both parties before the first filing.

FAQ

Does my IRA custodian prepare my Form 990-T?

No. The custodian is the technical filer and must sign the Form 990-T, but they do not prepare it. Some custodians have arrangements with tax preparers they can refer you to, but the responsibility for ensuring the return is accurately prepared and timely filed rests with you. You engage and pay a CPA to prepare the return; the custodian then reviews and signs it.

Can I prepare my own Form 990-T?

Technically yes — there is no legal requirement to use a CPA. Practically, the calculations involved (ADS depreciation, debt-financed percentage, UDFI allocation, multi-state apportionment) are complex enough that self-preparation creates significant risk of error. An incorrectly prepared 990-T can result in understated tax (leading to penalties and interest), overstated tax (leaving money in the IRS’s hands), or missed state filings. For any IRA with real UBTI exposure, professional preparation is strongly recommended.

What is the penalty for filing Form 990-T late?

Under IRC §6651, the failure-to-file penalty is 5% of the unpaid tax for each month or part of a month the return is late, up to a maximum of 25%. The failure-to-pay penalty is 0.5% of the unpaid tax per month, also up to 25%. If both apply, the combined rate is capped at 5% per month. Interest accrues from the due date at the federal short-term rate plus 3%. These penalties are imposed on the IRA’s tax liability — and must be paid from IRA assets.

Can my CPA also advise on prohibited transactions?

A SDIRA-qualified CPA with experience in IRC §4975 can flag many common prohibited transaction risks, but for complex situations — a proposed investment involving a family member’s business, a self-directed Checkbook IRA engaging in active transactions, or a partner buyout that could involve a disqualified person — you may need an attorney with ERISA or tax law experience in addition to a CPA. The CPA handles the numbers; the attorney handles the legal structure.

How long should I retain SDIRA tax records?

The IRS generally has three years from the filing date to audit a return, but the statute extends to six years if income is understated by more than 25%, and there is no statute of limitations for fraudulent returns or failure to file. For SDIRA records, best practice is to retain all records for the life of the investment plus seven years. Depreciation schedules in particular should be retained permanently, as they establish the original basis that determines gain on eventual disposition.

My CPA says IRAs never owe taxes. Should I be concerned?

Yes. This is a significant red flag. While it is true that ordinary IRA income (interest, dividends, capital gains from passive investments) is tax-deferred, IRAs that generate UBTI — through active business income, leveraged investment income (UDFI), or K-1 income from certain partnerships — do owe federal and potentially state taxes. A CPA who believes IRAs are categorically tax-exempt is not qualified to handle SDIRA tax reporting and could expose you to unpaid taxes, penalties, and interest by failing to file required returns.

Should the CPA fee be paid from IRA funds or personal funds?

CPA fees for work that is directly connected to the IRA’s investment activities — preparing Form 990-T, computing UBTI, preparing state returns — are generally payable from IRA assets as an investment expense. Your custodian will process a disbursement from the IRA to the CPA. Do not pay these fees from personal funds, as keeping them inside the IRA preserves the tax treatment of those assets and ensures the expense is properly associated with the IRA’s activity.
