The other stuff looks fine BUT the percent W/H for your state I have no idea....don't know which state. The fed W/H depends on your total income....is it enough? Run the numbers to see if you're paying in enough.
The % that won't raise a red flag depends on the type of biz and you involvement.....the services you render and your expertise. I'd say for an ALL SERVICES biz where you run the entire show and do all the work not to go anywhere below 50% and even that's pushing it. If it were me I'd stick to around 75% as a salary for a biz where I provided all of the services. You're pretty much safe there.
