TurboTax doesn't generate Form 8615

My child received a 1099-B with Total Proceeds > $8000. However, he has a Realized Loss of -$140. If I understand correctly, I have to file taxes for him since I can't add his 1099-B to my taxes. (I filed an extension for him because we hadn't yet received a K-3.)

 

It also looks like he meets all the requirements to file a Form 8615. His unearned income (which I understand is gross unearned income) is > $2600. However, it looks like the TurboTax Form 8615 shows his "Net Capital Gain" to be 0. So even though he meets the requirements to file a form, since the Net Capital Gain is 0, then is no form is needed? I see a Form 8615 Worksheet, but no Form in TurboTax.

 

Thanks!

Kiddie tax doesn’t apply since he had no net unearned income.

The "proceeds" are not income.  Only the gain/loss is "income".  In your child's case, their gross income is negative $140 (plus any other income he may have). 

 

Unless he has other income, he isn't even required to file a tax return (assuming the 1099-B shows the Basis of the sale).

Thanks! Good to know for the future. The 1099-B has the cost basis. However, based on previous feedback on a thread titled, "How to handle a 1099B for a custodial account," it appeared that I had to file separately for my son. I can't figure out how to attach that thread on here.

For capital gains, "gross income" means the gain, not the proceeds.  

 

If the gain had been enough that he had to file, yes, he would need his own tax return (you couldn't report it on your return.

Since he has a loss you might want to file a return for him to carry it forward. If his AGI is zero give him a dollar of interest to enable e-filing or mail the return.
