Commissioner, 86 T.C. 85, 89 (1986). Accordingly, we find and hold that respondent timely issued the notice of deficiency to petitioners within the applicable period of limitations provided by section 6501(a), given that the Greenfields executed the Form 872-A extending the limitations period and that the extension remained in effect when respondent issued the notice of deficiency to them. C. Interest Petitioners argue that waiver of the period of limitations in Form 872-A applies only to tax, which petitioners view as exclusive of interest and penalties. In making this argument, petitioners rely on the literal language of Form 872-A, which, as petitioners rightly point out, references Federal tax but neither interest nor penalties. Respondent argues that Form 872-A constitutes a waiver that extends the period of limitations on the assessment of tax, interest, penalties, and additions to tax. This Court has held that use of the term “tax” in Form 872-A includes penalties and interest. See Pleasanton Gravel Co. v. Commissioner, 85 T.C. 839, 855 (1985) (citing Picard v. Commissioner, 28 T.C. 955, 961 (1957)).
