Identify the agreement requested
An examiner may ask a business owner to sign a consent extending the time to assess tax while an examination is still open. Do not treat the form as a routine acknowledgment that documents were received. Obtain the proposed agreement and ask the representative to explain the taxpayer, tax, years, expiration date, and scope. Keep the proposed form with the examination chronology so the owner can evaluate the request in the context of the actual unresolved work.
IRS Publication 1035 distinguishes fixed-date consents, such as Form 872, from open-ended consents, such as Form 872-A. It explains that a taxpayer may refuse an extension or seek mutually agreed limits on issues or time. Those choices have tradeoffs, including the time available to finish the examination and pursue administrative consideration. A refusal does not itself prove the return correct or guarantee that the IRS will make no timely assessment.
Confirm the existing statute before comparing options
Have the professional calculate the existing assessment period from the actual filing history, applicable exceptions, prior consents, and any suspensions. A general three-year description is not a complete statute calculation. Record the legal taxpayer and each tax period separately. If the company and the owner are both under examination, they may have different clocks even though the same records are relevant to both.
Consider a hypothetical owner whose advisor identifies two unresolved issues: a supported equipment-basis adjustment and a disputed revenue-timing adjustment requiring customer evidence. The examiner requests a six-month extension. The owner should ask which remaining tasks require that time and whether a narrower agreement is appropriate. The six-month period is an illustrative proposal, not a standard legal entitlement for either side. The decision depends on the actual status, risks, and alternatives.
Connect the extension to a concrete completion plan
Create an action schedule showing documents still needed, who will supply them, expected review dates, and any administrative appeal work. If a customer must locate historical service records, obtain a realistic delivery estimate. If the accounting evidence is already complete, ask what analysis remains. An extension is easier to assess when it supports a defined task instead of an indefinite statement that the audit is taking longer than expected.
Ask the representative to explain the consequence of signing, declining, or proposing different terms. The examiner may need to act on the available record if time is insufficient. Additional time may also permit the taxpayer to present evidence or pursue an administrative resolution. Neither outcome is automatic. Keep the owner’s commercial concerns visible, including financing, sale negotiations, management distraction, and the cost of maintaining the examination team.
Review limits and execution carefully
A restricted consent can require precise drafting and agreement by the IRS. Have the professional review how the language identifies issues and how related adjustments are treated. Do not add handwritten restrictions without understanding their legal effect or whether the IRS has accepted them. Preserve the fully executed agreement and confirmation, not only the taxpayer’s signed draft. Assign the revised expiration to the case calendar after the agreement is effective.
For an open-ended consent, review the actual termination mechanism and any continuing periods rather than assuming an ordinary letter immediately closes the statute. For a fixed-date consent, identify any provisions that can affect the period after signing. The owner should know who will monitor the agreement and whether another extension request is expected. An old consent can remain important after the business changes preparers, sells assets, or closes an entity.
Track refund and closing consequences separately
Assessment and refund limitations are related procedural subjects, but an assessment consent is not a blanket extension of every possible refund deadline. Ask the advisor to analyze any overpayment claim and lookback limitation separately. Similarly, the consent does not extend unrelated payment, return-filing, court-petition, or information-response deadlines merely because the audit remains open. Keep those dates on distinct lines in the case register.
Close the decision file with the proposed terms, advisor analysis, owner instruction, executed agreement if any, and updated action schedule. Revisit the schedule before the new expiration instead of waiting for another urgent signature request. When the examination concludes, retain the consent with the final determination and refund or payment history. The useful result is an informed choice about time and scope, supported by a completion plan the owner can monitor, rather than an automatic signature that nobody remembers when the next deadline approaches.
