Look at Line 9 of the VA tax return, which you can see here:
https://www.tax.virginia.gov/sites/default/files/taxforms/individual-income-tax/2019/760-2019.pdf
It states that for filing status 1 (Single), if your VA adjusted gross income is less than $11,950, your tax is zero.
That's why you're not required to file a VA return if your VA AGI is below that level. But as stated before, you would have to file if you wanted a refund of any withheld VA taxes.
**Answers are correct to the best of my ability but do not constitute tax or legal advice.
