The Trump Tax Plan that passed in late 2017 has raised opinions from all sides of the table. One item buried in the bill impacts 529 plans. Effective in 2018, your child's 529 plan can be used for K-12 education expenses in addition to qualified college costs.
You can now use up to $10,000 a year to fund your kid's private or home school education needs. Until now the only tax break for private & religious education expenses was a Coverdell ESA, but those accounts can be very limited. This change may be helpful to many families who choose to send children to private schools.
