Isabella files her income tax return 35 days after the due date of the return without obtaining an extension from the IRS. Along with the return, she remits a check for $40,000, which is the balance of the tax she owes. Note: Assume 30 days in a month. Disregarding the interest element, enter Isabella's failure to file penalty and and failure to pay penalty.

a. Failure to pay penalty = 400

b. Failure to file penalty = $4,000

Explanation:

The monthly rate for failure to pay penalty is 0.5% while the failure to file penalty.

Since it is assumed that there are 30 days in a month, the 35 days after the due date of the return without obtaining an extension from the IRS is will be counted as 2 months regardless of the fact that the second month is just 5 files when she filed.

Therefore, we have:

a. Failure to pay penalty = $40,000 * 0.5% * 2 = 400

b. Failure to file penalty = ($40,000 * 5% * 2) = $4,000

c. Total penalties = (Failure to file penalty - failure to pay penalty for the same period) + Failure to pay penalty = ($4,000 - $400) + $400 = $4,000.

Therefore, the total penalty Isabella will pay is $4,000.
