Yes this is the way to go. I have a shutoff near the pipe that the city water comes in but the valve was nonfunctional. I had to schedule a plumber, then ask the city to shutoff my water on that day, the plumber came and replaced the valve, and the city came back to turn on the water. Basically the same process applies to you but with installing a valve rather than replacing one.
What a backward system we have in filing taxes. Explaining the system to teenagers makes me apologize to them for how stupid the system is. Hope to see more progress in this goal.
