A new pace in war finance was set by the United States when it became a belligerent. It had to provide for an increase of taxation ascending from the point of $3,000,000,000 in 1917 to over $8,000,000,000 in 1918. The largest source of estimated revenue was from taxes on excess profits, including war profits of $3,100,000,000, and the next was from taxes on incomes, $1,482,186,000 from individuals, and $828,000,000 from corporations. The New York _Journal of Commerce_ shows by the following table the difference between the old and the new system of taxation. Exemptions under the new law were the same as under the old: $1,000 for single persons and $2,000 for married, $200 additional allowed for each dependent child under eighteen years of age: Incomes Tax Under Old New Law Law $2,500 $10 $30 3,000 20 60 3,500 30 90 4,000 40 120 4,500 60 150 5,000 80 180 5,500 105 220 6,000 130 260 6,500 155 330 7,000 180 400 7,500 205 470 8,000 235 545 8,500 265 620 9,000 295 695 9,500 325 770 10,000 355 845 12,500 530 1,320 15,000 730 1,795 20,000 1,180 2,895 25,000 1,780 4,240 30,000 2,380 5,595 35,000 2,980 7,195 40,000 3,580 8,795 45,000 4,380 10,645 50,000 5,180 12,495 55,000 5,980 14,695 60,000 6,780 16,895 70,000 8,880 21,895 80,000 10,980 27,295 100,000 16,180 39,095 150,000 31,680 70,095 200,000 49,180 101,095 300,000 92,680 165,095 500,000 192,680 207,095 1,000,000 475,180 647,095 5,000,000 3,140,180 3,527,095 The following estimated yield from other sources is given by the same authority: "Transportation--Freight, $75,000,000; express, $20,000,000; passenger fares, $60,000,000; seats and berths, $5,000,000; oil by pipe lines, $4,550,000.
