Yes, this is okay.
The IRS allows you to round to the whole dollar amount.
Rounding off dollars.
You can round off cents to whole dollars on your
return and schedules. If you do round to whole dollars, you must
round all amounts. To round, drop amounts under 50 cents
and increase amounts from 50 to 99 cents to the next dollar. For
example, $1.39 becomes $1 and $2.50 becomes $3.
If you have to add two or more amounts to figure
the amount to enter on a line, include cents when adding the amounts
and round off only the total.
