Section 1331 of the House bill and Senate amendment is deleted in the House amendment.

Special tax provision: Section 1331 of title 11 of the House bill and the comparable provisions in sections 1322 and 1327(d) of the Senate amendment, pertaining to assessment and collection of taxes in wage earner plans, are deleted, and the governing rule is placed in section 505(c) of the House amendment. The provisions of both bills allowing assessment and collection of taxes after confirmation of the wage-earner plan are modified to allow assessment and collection after the court fixes the fact and amount of a tax liability, including administrative period taxes, regardless of whether this occurs before or after confirmation of the plan. The provision of the House bill limiting the collection of taxes to those assessed before one year after the filing of the petition is eliminated, thereby leaving the period of limitations on assessment of these nondischargeable tax liabilities the usual period provided by the Internal Revenue Code [Title 26].

The court may revoke an order of confirmation procured by fraud, after notice and hearing, on application of a party in interest filed within 180 days after the entry of the order. Thereafter, unless a modified plan is confirmed, the court is to convert or dismiss the chapter 13 case as provided in section 1307.
