Fund an Individual Retirement Account
Contrary to the large number of changes caused by the new tax law, you can still stash $5,500 pretax in a traditional tax-deferred IRA. Come to think about it, this could save a taxpayer in the 25% tax bracket $1,375.
Another option is to fund an IRA on your spouse’s behalf, but only as long as one of your incomes is high enough to match the IRA contribution.
