Summary

If a taxpayer does not tell the IRS by the deadline about a change in foreign tax, the IRS adds a penalty to the extra tax owed because of that change. The penalty starts at 5% if the delay is up to 1 month and increases by 5% for each additional month or part of a month, but cannot go over 25%. No penalty applies if the missed notice was caused by reasonable cause and not by willful neglect. "Foreign tax redetermination" means a change in foreign tax for which a notice is required under section 905(c) or section 404A(g)(2).
