If your Virginia adjusted gross income is below the filing threshold, your tax is zero.
I earned about $18500 in investment interest and $3000 in long and short-term net capital loss, $0 in traditional IRA/HSA contributions (since I am ineligible for tax deductions due to$0 W2/1099 income), so my federal AGI should be $15500. I also contributed $4000 to pre-tax Virginia 529 (up to $4000 income tax deduction). I am not sure if my Virginia AGI is $15500 or $11500, which is below the filing threshold.
