Nondividend Distributions
Some distributions are a return of your cost (or other basis). They won’t be taxed until you recover your cost (or other basis). You must reduce your cost (or other basis) by these distributions. After you get back all of your cost (or other basis), you must report these distributions as capital gains on Form 8949. For details, see Pub. 550.
Dividends on insurance policies are a partial return of the premiums you paid. Don’t report them as dividends. Include them in income on Schedule 1, line 8z, only if they exceed the total of all net premiums you paid for the contract.
If you are including your child’s dividends on either line 3a or 3b, check the applicable box on line 3c.
