Summary

Failing to tell the IRS by the required deadline about a foreign tax redetermination means a penalty is added to the tax increase from that redetermination, unless you show a good reason and that you didn’t neglect it on purpose. The penalty is 5% for the first month and 5% for each additional month or part of a month, but it can’t be more than 25% of the tax increase. A "foreign tax redetermination" is a change in foreign tax that you must report under certain rules (for example, section 905(c) or 404A(g)(2)).
