Embed the 529 state tax calculator
One line of code. When a state changes its cap or its credit, the embedded calculator changes with it.
Who uses it: a school newsletter before the December contribution rush, a parents' forum comparing home-state plans, a teacher of a personal finance class. Terms: leave the credit line under the frame visible, do not crop or restyle the frame, and do not set it beside an offer to sell a plan, a fund or advice. The frame sets no cookie and tells us nothing about your readers. Questions or a state rule you think is out of date: contact page.

They are not tax, legal or investment advice for your own case; your state revenue department or a tax professional can confirm it. Nobody pays us to point you to a plan.
