Subdivision 2. In addition to the income tax provided under this section (herein referred to as the normal income tax) there shall be levied, assessed, and collected upon the net income of every individual an additional income tax (herein referred to as the additional tax) of 1 per centum per annum upon the amount by which the total net income exceeds $20,000 and does not exceed $50,000, and 2 per centum per annum upon the amount by which the total net income exceeds $50,000 and does not exceed $75,000, 3 per centum per annum upon the amount by which the total net income exceeds $75,000 and does not exceed $100,000, 4 per centum per annum upon the amount by which the total net income exceeds $100,000 and does not exceed $250,000, 5 per centum per annum upon the amount by which the total net income exceeds $250,000 and does not exceed $500,000, and 6 per centum per annum upon the amount by which the total net income exceeds $500,000. All the provisions of this section relating to individuals who are to be chargeable with the normal income tax, so far as they are applicable and are not inconsistent with this subdivision of paragraph A, shall apply to the levy, assessment, and collection of the additional tax imposed under this section.
