The cost of a private letter ruling from the IRS has two parts. The government user fee is $43,700 for most requests received after January 29, 2026, dropping to $3,450 for filers with gross income under $400,000 and rising to $121,600 for an original advance pricing agreement.1Internal Revenue Service. Revenue Procedure 2026-1 Appendix A Schedule of User Fees The attorney or CPA fees for preparing the request are the other part, and for anything beyond a routine request they typically exceed what you pay the IRS, pushing total costs for complex rulings past $100,000.
2026 IRS User Fee Schedule
The IRS publishes its fees each year in Revenue Procedure 2026-1, Appendix A.2Internal Revenue Service. Code Revenue Procedures Regulations Letter Rulings The fee is non-refundable and must be paid through pay.gov before the IRS will process the request. What you owe depends on what you’re asking for:
- General letter rulings: $43,700. This covers most requests that don’t fall into a specific carve-out, as well as closing agreements on proposed or completed transactions.
- Relief under Section 301.9100-3 (extensions of time to make a tax election): $14,500.
- Non-automatic accounting method changes on Form 3115: $13,225. Extensions of time to file Form 3115 run $13,900.
- Accounting period changes on Form 1128 or Form 2553: $5,750. Extensions for these filings cost $6,100.
- Advance pricing agreements: $121,600 for an original APA, $65,900 for a renewal, and $57,500 for a small-case APA.
The spread is wide. A small business asking to change its tax year pays $5,750. A multinational requesting an original advance pricing agreement pays more than twenty times that.1Internal Revenue Service. Revenue Procedure 2026-1 Appendix A Schedule of User Fees
Reduced Fees for Smaller Filers
Taxpayers who fall under the IRS gross income thresholds pay sharply less. Two tiers apply:
- Gross income under $400,000: $3,450 for any letter ruling, accounting method or period change, or closing agreement request.
- Gross income between $400,000 and $10 million: $9,775 for the same categories.
To claim either rate, you have to include a signed certification of your gross income with the request. Skip the certification and the IRS charges the full standard fee.1Internal Revenue Service. Revenue Procedure 2026-1 Appendix A Schedule of User Fees
Requests That Skip the Fee Entirely
A few categories pay nothing. Federal departments and agencies seeking rulings on behalf of federally funded programs owe no fee. Eligible employers requesting a determination letter for a qualified retirement plan within its first five plan years are exempt as well. And automatic accounting method changes filed on Form 3115 under the automatic change procedures carry no user fee, because the IRS grants consent to those changes without individual review.3Internal Revenue Service.

Attorney and CPA Fees
The government charge is rarely the largest line item. A private letter ruling isn’t a form you fill out; it reads more like a legal brief arguing for a specific tax treatment, with a full statement of facts, a discussion of every relevant authority, and proposed ruling language the IRS can adopt word for word.
Specialized tax attorneys at larger firms commonly bill $400 to $1,000 or more per hour for this work. A straightforward request, such as extension-of-time relief for a missed election, might take 30 to 60 hours of attorney time. A ruling on a complex corporate restructuring or a novel transaction can absorb hundreds of hours across multiple attorneys, and professional fees alone can pass $200,000. The National Taxpayer Advocate has noted that historically the IRS filing fee sometimes exceeded the legal costs for simpler rulings, but that’s the exception, not the pattern for complex matters.
The work generally runs through three phases, each generating billable hours. Attorneys first research whether the IRS is likely to rule favorably, reviewing published guidance, judicial precedent, and analogous private letter rulings issued to other taxpayers. They then draft the submission package, which is the most labor-intensive step. Finally, they handle correspondence with the assigned IRS attorney during review, including any conferences.
Some firms quote flat fees for routine categories like missed-election relief, which gives you cost certainty upfront. For anything involving a genuinely novel question, expect hourly billing and a retainer. The professional fee is the single biggest variable in what a ruling actually costs.
One way to control that variable is a pre-submission conference. The IRS encourages these for complex transactions, and they let you discuss the substantive issues with IRS personnel before you invest in a full submission. If the conference reveals that a favorable ruling is unlikely, you save the tens of thousands of dollars a full submission would have cost.
What Happens to the Money if You Withdraw
You can withdraw a ruling request at any time before the IRS signs and issues the final letter.4Internal Revenue Service. Chief Counsel Directives Manual 32.3.1 – Letter Rulings Withdrawing is a common move when the IRS signals it will rule against you, because taking the request off the table avoids a written adverse determination that could complicate future audits.
The user fee is generally non-refundable upon withdrawal. The IRS keeps everything you submitted. A narrow exception exists: if the IRS provides only general information rather than the requested ruling, you may be entitled to a refund.4Internal Revenue Service. Chief Counsel Directives Manual 32.3.1 – Letter Rulings In practice, losing the full user fee plus every dollar of professional preparation is the price of an unsuccessful attempt. That risk is why the pre-submission conference is worth the effort.
What You Get for the Price
A private letter ruling binds the IRS with respect to the specific taxpayer and the specific transaction described, assuming the facts you provided were complete and accurate. It doesn’t create precedent that other taxpayers or even IRS personnel can rely on.5Internal Revenue Service. TEB Private Letter Ruling Some Basic Concepts If material facts were misrepresented or omitted, the IRS can revoke the ruling retroactively.
That protection is what justifies the price tag. For a transaction where the tax consequences are genuinely uncertain and the dollars at stake are large enough, a ruling eliminates the risk of an adverse audit outcome years later. For most taxpayers and most transactions, the cost is prohibitive relative to the benefit. The ruling process is built for situations where ambiguity in the law creates real exposure, not for confirming routine positions that published guidance already covers.
