I am going start using TaxJar.com for my web application to calculate the required sales tax for an order.

I notice on their sites API that there can sometimes be a State, City and County tax that are all different amounts.

My question is how are these taxes paid. Does there need to be a total for each tax point at the end of the year, so a total for every City, State and County? This seems too complicated so I am guessing totals are more general. What level of detail is required when submitting a yearly tax calculation.

This is for a Californian C-Corp.
