Compute the failure to pay and failure to file penalties for John, who filed his 2015 income tax return on December 20, 2016, paying the $10,000 amount due at that time. On April 1, 2016, John received a six-month extension of time in which to file his return. He has no reasonable cause for failing to file his return by October 15 or for failing to pay the tax that was due on April 15, 2016. John's failure to comply with the tax laws was not fraudulent.
