Overhead takes different prepositions depending on what you're actually saying about it -- and getting the preposition wrong is one of the fastest ways a fluent sentence starts to sound slightly foreign.
Name who is affected with overhead for (not "overhead about"), and name the method that lowers it with reduce overhead by plus a gerund (not "reduce overhead for/to/about").
'Overhead for': naming who carries the load
When you want to say which team or function is affected by a source of overhead, the preposition is "for."
"The custom reporting requirement adds overhead for the support team -- not 'overhead about the support team.'"
"About" doesn't work here because overhead isn't a topic you're discussing about someone -- it's a load that lands on them.
'Reduce overhead by' plus a gerund: naming the fix
When you're naming the action that lowers overhead, the pattern is "reduce overhead by" followed by an -ing form.

"Switching to automated expense reconciliation will reduce overhead by cutting the manual matching work finance does every month."
"To" and "about" both fail here for the same underlying reason: "by" is the preposition English uses to introduce the method or means of an action, and reducing overhead is exactly that -- an action with a method attached.
In an executive update
A third pattern matters specifically in formal or executive writing: "overhead associated with" introduces the source of the cost or burden. Use "overhead associated with" governance or support, and "reduce overhead by" automating -- not "overhead about governance" or the awkward countable forms "an overhead" and "overheads smaller."
Executive readers notice small grammar slips more than casual ones do, since the register is already more careful -- getting these three patterns right is disproportionately worth it in that context.
Practice scenarios
Practice using overhead in situations like:
- naming which team a source of overhead affects
- describing the specific action that will reduce overhead
- writing an executive update that names overhead's source accurately
Useful practice phrases:
- "[X] adds overhead for [team]."
- "We can reduce overhead by [gerund]."
- "The overhead associated with [governance/support] is..."
The right preposition is what tells your reader whether you're naming a cause, an effect, or a fix.
Get 'for,' 'associated with,' and 'by' straight, and overhead sentences stop needing a second read.
