To avoid the assessment becoming final, by when must the taxpayer submit all relevant supporting documents in a reinvestigation?

• A. Within 60 days from protest filing
• B. Within 90 days
• C. Within 30 days from protest filing
• D. Within 60 days from filing of letter of protest

Answer: (D)

In reinvestigation, you have a defined window to submit all relevant supporting documents to prevent the assessment from becoming final. That window is 60 days from the filing of the letter of protest. This starts the moment you formally protest and begins the review of your evidence. If you don’t provide the documents within that 60-day period, the assessment can become final and enforceable. The other timeframes don’t align with this rule because they either miss the exact start point (the filing of the letter of protest) or don’t reflect the mandated 60-day period.
