Unable to get formula to subtract 30 minutes for lunch if over 6 hours are worked

I am working on a time sheet and so far I have the formula figured out to add up the hours from the time I input as =TEXT(C1-B1,"h:mm"). The formula I am trying to figure out is if this formula equals 7:00 and I need to subtract 30 minutes if the total is over 6:00 what is my next step. Trying to set up a payroll and need to subtract lunch if a person works over 6 hours. Any help would be greatly apprieciated.

Try

=TEXT((C1-B1)-(C1>TIMEVALUE("07:00:00"))*TIMEVALUE("00:30:00"),"h:mm")

Using TEXT function is normally a mistake - as the name implies it formats the result as text which might inhibit your ability to use that result in further calculations, for your initial formula a simple subtraction would be better

=C1-B1

then use formatting to format cell as h:mm

To subtract 0:30 if the initial length is 6 hours or more try

=C1-B1-IF(C1-B1>="6:00"+0,"0:30")
