On today’s Your Call, on Tax Day, we’ll have a conversation about the tax system. The US government collects about a quarter of its gross domestic product through taxes. Who's paying the most taxes? Who's not paying taxes? Join us at 10 or email firstname.lastname@example.org. What would a fair tax system look like -- and would any of the proposals out there now move us toward a better system? What would you change? It’s Your Call, with Rose Aguilar and you.
