No IRS source or independent study identified here supports the claim that the first 48 hours decide most criminal tax cases. That wording comes from McCauley Law Offices, not from a published IRS statistic or an established universal deadline. IRS-CI describes a process involving evidence gathering, internal review and possible referral—not an automatic decision triggered by an agent’s first contact.
Where the “first 48 hours” claim comes from
McCauley Law Offices uses the phrase “The first 48 hours decide most criminal tax cases” on its criminal tax defense page. It should be understood as the firm’s claim, not an IRS rule or a demonstrated fact about most cases. No supporting statistic or independent study was identified for the assertion.
The title also names the Carroll County Mirror-Democrat. The available source record identifies an October 3, 2026 syndicated announcement about the firm, but does not establish that the named newspaper published that announcement as an original article. The firm’s own page is the source for its 48-hour wording.
What happens after IRS-CI opens an investigation
IRS Criminal Investigation (IRS-CI) says investigations can begin through several channels. Agents then gather and analyze evidence. The process includes supervisory and quality reviews, and an investigation may be discontinued or not accepted for prosecution. If IRS-CI recommends prosecution, the matter may go to the Department of Justice or a U.S. Attorney for further review; it is not a final charging decision by the agent who made contact.

- Information reaches IRS-CI. Investigations may start from different sources; an initial inquiry does not itself establish that charges will follow.
- Agents investigate. IRS-CI gathers and evaluates evidence as part of its criminal investigation.
- The matter receives internal review. Supervisory and quality reviews occur before a prosecution recommendation proceeds.
- A referral may receive further review. DOJ’s Tax Division evaluates certain requests and participates in criminal tax cases. A referral is not the same thing as a prosecution or conviction.
This sequence does not prove that timing is irrelevant in any individual case. It does show why an unqualified “most cases are decided in 48 hours” statement should not be treated as a general description of IRS procedure.
What the IRS’s FY 2025 numbers do—and do not—show
IRS Publication 55-B, revision 4-2026, reports these Criminal Investigation totals for fiscal year 2025:
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
| IRS-CI activity | FY 2025 total |
|---|---|
| Referrals for prosecution | 2,043 |
| Convictions | 1,611 |
These are activity counts, not outcomes for the same group of cases. The IRS notes that investigations can span fiscal years, so dividing 1,611 convictions by 2,043 referrals would not produce a valid conviction rate. The totals also say nothing about whether a decision was made within 48 hours.
If an IRS-CI agent contacts you
Take the contact seriously, but first establish who is contacting you and what they are asking for. IRS-CI provides an Employee Verification Tool for checking whether someone is an IRS employee; the IRS cautions that the tool is not available during all enforcement actions. If it is unavailable, use an official IRS channel to seek verification rather than relying only on details supplied in the contact.

The distinction matters: a request to talk is not the same as a summons requiring testimony or records. Because the consequences and options depend on the particular circumstances, a person facing possible criminal exposure should promptly consult a lawyer qualified in criminal tax matters before deciding how to respond. This is general information, not advice for an individual case.
A voluntary interview request
An agent may ask to speak with you. IRS interview procedures address interviews and rights advisements in specified circumstances, including when a witness is a subject or may become one. Do not assume from the invitation alone what your status is or what you should say; get advice based on the contact and your situation.
Rank #4
A summons for testimony or records
A summons is formal process, not merely an invitation to have a conversation. IRS procedures address summonses for taxpayer records and testimony separately from ordinary interviews. If you receive one, have counsel review the document and deadlines promptly rather than ignoring it or treating it as an informal request.

Representation by a lawyer and the statutory privilege available to some federally authorized tax practitioners are different protections. Internal Revenue Code § 7525 extends practitioner privilege only to specified noncriminal tax matters and proceedings; it does not extend that privilege to criminal tax matters. An accountant is not automatically covered by attorney-client privilege. Whether a particular accountant’s work under a lawyer-directed arrangement is protected depends on the facts and should be assessed by counsel.

What the firm’s advice means—and what it does not establish
In an October 3, 2026 announcement, Gregory McCauley Jr., identified there as a tax attorney at McCauley Law Offices, said: “A special agent’s visit is not the moment to explain a return,” That is the firm representative’s advice, not an official IRS statement or a one-size-fits-all instruction. It reinforces the value of getting qualified advice before responding, but it does not establish that every person should refuse every interview or take the same step.
