I always include permit costs and the time to get them. They are part of the job.
Some of the cities are a lot more costly than others.
Permits, taxes and other costs should be included in your bid or shown as a line item in T&M billing. You have to pay them for you to do the job you contracted for, so you should be paid for your time and costs.
BTW
How many of you have to charge sales tax?
Recently (1 OCT ) nebraska raised it sales tax rate and now wants certan contractors to charge sales tax on materials AND Labor.
