More generally, there are at least two ways to do this. 

First, produce a new classified variable and then -tabulate- it. 

The example here could have been 

gen upper = 10 * ceil(wage / 10) 
tab upper 

Second, produce a table on the fly. -tabcond- on SSC has some limited functionality 
in this respect.

-egen, cut- is for you. -ta- afterwards..
