- If you disagree, follow the protest instructions and keep proof of delivery or submission.
Timing
The IRS says a Letter 1153 protest generally must be filed within 60 days from the date of the letter, or 75 days if the letter is addressed outside the United States. Use the address, date, and instructions on your copy.
