My post below is incorrect.
The Tax Cuts and Jobs Creation Bill DOES allow use of 529 plans for K-12 education expenses up to $10,000 per year.
The Cruz amendment proposing use of 529 plans funds for homeschooling expenses was the stricken provision.
Thank you to those below who clarified the change allowed by the new law and my error.
Your reporting has incorrectly stated that the final tax bill as signed into law last week contained a provision allowing for use of 529 Plans for K-12 education expenses. This provision was stricken from the bill very late in the legislative process.
This K-12 education provision was contained in the bill originally approved by the House of Representatives, but due to Senate rules relating to the reconciliation process, the K-12 provision was stricken from the bill prior to passage of the revised bill by the Senate.
The House re-voted on the revised bill without the K-12 education provision for 529 Plans and approved the revised bill on December 20. The revised tax bill without K-12 education was signed into law on December 22.
