Other Helpful Information
On your return, you must round off fractions of a gallon to the nearest whole gallon. Round down to the next lowest whole gallon all fractions of a gallon less than a half-gallon. Round up to the next highest whole gallon all fractions of a gallon of a half-gallon or more.
Rounding Off to Whole Dollars
You must round off cents to the nearest whole dollar on your returns and schedules. If you do not round, DRS will disregard the cents. Round down to the next lowest dollar all amounts that include 1 through 49 cents. Round up to the next highest dollar all amounts that include 50 through 99 cents. However, if you need to add two or more amounts to compute the amount to enter on a line, include cents and round off only the total.
Example: Add two amounts ($1.29 + $3.21) to compute the total ($4.50) to enter on a line. $4.50 is rounded to $5.00 and entered on a line.
