Plain-English summary

This Chief Counsel advice addresses when interest on an estimated-tax penalty accrues. It states that interest begins on the date of notice and demand if the taxpayer does not pay within 21 days of notice and demand, or within 10 business days in certain cases. The advice cites IRC § 6601(e)(2)(A) and notes that the writer found no reason to reach a different conclusion.

Subject: interest on penalty

As we previously discussed by phone, I think interest on an estimated tax penalty accrues from the date of notice and demand if a taxpayer fails to pay the amount within 21 days of notice and demand (or 10 business days in certain cases.) See I.R.C. § 6601(e)(2)(A). I haven't located anything that would lead me to believe otherwise.
