Form 8275: When and how to disclose tax positions to the IRS

You claimed a deduction on your tax return that you believe is legitimate, but you recognize it might raise questions. The tax law may be ambiguous in your specific situation. You applied a rule in a way that makes sense but has not been explicitly blessed by the IRS. Your interpretation may favor you in an area where the IRS has been aggressive.

You are confident enough in your position to take it, but not confident enough to assume the IRS will automatically agree. If they audit and disagree, you are prepared to pay additional tax. What you are not prepared for is the 20% accuracy-related penalty on top of that tax.

This is where tax position disclosure comes in. Form 8275 allows you to tell the IRS exactly what you did and why, and that disclosure can protect you from penalties even if your position is ultimately disallowed.

Disclosure reduces penalty risk for uncertain tax positions

The accuracy-related penalty under Section 6662 applies when taxpayers understate their tax liability due to positions that lack adequate support. The penalty is 20% of the underpayment, which can substantially increase the cost of a position that turns out to be wrong.

• Substantial authority is the default standard. Without disclosure, your position must have "substantial authority" to avoid accuracy penalties. Substantial authority is a relatively high standard, requiring that the weight of authorities supporting your position is substantial compared to authorities opposing it. Not every defensible position meets this test.
• Adequate disclosure lowers the standard to a reasonable basis. When you properly disclose a position on Form 8275, the penalty protection disclosure reduces the required standard from substantial authority to reasonable basis. A reasonable basis is a lower threshold, meaning positions that would otherwise trigger penalties without disclosure become penalty-protected with disclosure. The difference matters. A position with a 35% chance of prevailing might have a reasonable basis but not substantial authority. Without disclosure, that position triggers penalties if disallowed. With disclosure, the same position is penalty-protected.
• Disclosure demonstrates good faith. Filing a disclosure statement, IRS Form 8275, signals that you are not hiding anything. You took a position, notified the IRS, and explained your reasoning. Even if they disagree with your conclusion, the transparency demonstrates good faith and eliminates the penalty designed to punish taxpayers who take aggressive positions without disclosure.

This is not an admission that your position is wrong. Many disclosed positions survive audit. The disclosure protects you if it does not.

When to disclose an uncertain tax position

Not every tax position requires disclosure. The decision depends on the strength of your position and the specific circumstances.

1. Disclose when you have a reasonable basis but lack substantial authority. This is the sweet spot where disclosure provides the most value. Your position is defensible and has legitimate support, but the authorities are mixed or limited. Without disclosure, you risk penalties. With disclosure, you preserve your ability to take the position while eliminating penalty exposure.

2. Do not disclose when you have substantial authority. If your position clearly meets the substantial authority standard, disclosure is unnecessary for penalty protection. You may choose to disclose anyway for other reasons, but it is not required to avoid penalties.

3. Do not disclose when you lack a reasonable basis. Disclosure does not protect positions that fall below the reasonable basis threshold. If your position is frivolous or has no legitimate support, disclosing it does not immunize you from penalties. The form protects positions in the middle ground, not for positions that should not be taken.

4. Use Form 8275-R for positions contrary to regulations. If your position directly contradicts a Treasury regulation, Form 8275 is not sufficient. You must use Form 8275-R, which has a higher disclosure standard and different requirements. The Form 8275 instructions specifically note this distinction.

5. Consider disclosure for positions that may invite scrutiny. Even if your position has substantial authority, you might choose to disclose if the item is large, unusual, or involves an area where the IRS is actively challenging taxpayers. The disclosure ensures that if the issue comes up, you have already explained your reasoning.

Completing Form 8275 correctly

An ineffective disclosure provides no penalty protection. The form must be completed properly to serve its purpose.

Part I identifies the return items. List each item you are disclosing with the form number and line where it appears on your return. For example, if you are disclosing a deduction on Schedule C, identify the specific line. If you are disclosing the treatment of a transaction that affects multiple lines, list each one.

Part II explains the detailed description. This is the substance of your disclosure. Describe the facts giving rise to the item, the tax treatment you applied, and your legal basis for that treatment. Be specific. The "Business expense deduction" disclosure is inadequate. "Deduction of $15,000 for consulting fees paid to XYZ Company, treated as ordinary and necessary business expense under Section 162, based on the services rendered for business development purposes" is adequate disclosure.

Part III provides additional information. Use this section for any supplementary explanation that does not fit in Part II. Complex positions may require extensive discussion of the facts, legal authorities, and reasoning supporting your treatment.

Cite your authorities. The disclosure should reference the statutory provisions, regulations, court cases, IRS guidance, or other authorities supporting your position. You do not need to write a legal brief, but you should show that your position has a legitimate basis in tax law.

Attach to the return for the relevant year. Form 8275 files with the tax return for the year containing the disclosed position. It becomes part of your return and is available to IRS examiners if your return is selected for audit.

What disclosure does and does not accomplish

Understanding the limits of disclosure prevents misplaced expectations.

1. Disclosure protects against accuracy penalties. If the IRS disagrees with your position and assesses additional tax, adequate disclosure means the 20% accuracy penalty does not apply. You owe the tax and interest, but not the penalty.

2. Disclosure does not prevent an audit. Filing Form 8275 does not flag your return for examination, but it also does not shield you from audit. The IRS may still select your return through normal processes and may still challenge your disclosed position.

3. Disclosure does not guarantee your position survives. Penalty protection is not the same as position validation. The IRS can still determine that your position is incorrect and assess additional tax. You avoid the penalty add-on.

4. Disclosure creates a record. The form documents your reasoning at the time you filed. If years later the IRS questions your position, you have contemporaneous documentation of what you did and why. This can be valuable in demonstrating that your position was thoughtful and well-supported.

The peace of mind calculation

Many taxpayers forfeit legitimate tax benefits out of fear of an IRS challenge. They see an ambiguous area, recognize that their favorable interpretation might be questioned, and choose not to take the position.

Form 8275 offers an alternative. Take the position, disclose it, and eliminate the penalty risk. If the IRS disagrees, you pay the additional tax you would have owed anyway. If they do not, you captured a legitimate benefit you otherwise would have left on the table.

The calculation favors disclosure in most situations where you have a reasonable basis position. The cost of disclosure is minimal. The benefit is penalty protection that lets you take defensible positions without excessive fear of the consequences.

Professional service firm owners regularly face these decisions. Reasonable people can disagree about the proper treatment of many transactions. The tax code is complex, and IRS positions are not always clear or consistent.

Rather than avoiding every uncertain tax position, use disclosure strategically. Identify positions that benefit from penalty protection disclosure, complete Form 8275 properly, and file your return with confidence that you have done everything right, regardless of how the IRS eventually views your position.

The form exists precisely to enable this kind of thoughtful, transparent tax planning. Use it!
