The rates that apply to married joint filers under the bill are the same as the rates that apply to single individuals, fiduciaries, and heads of households, but the income limitations are higher. The lowest bracket applies to taxable income not exceeding $10,000; the second bracket applies to taxable income exceeding $10,000, but not $20,000; the third bracket applies to taxable income exceeding $20,000, but not $300,000; the fourth bracket applies to taxable income exceeding $300,000, but not $1,000,000; and the fifth bracket applies to taxable income exceeding $1,000,000.
