It depends but you would only need to pay VA nonresident state income taxes on any wages related to your trips to VA and only if you meet the VA nonresident filing requirements
In most cases, if you are a remote worker, the sourcing of your income is where it is earned (WA in your case) not where the company is located (VA). However, since you actually traveled to the VA company headquarters, if you performed any work while in VA, then this will be considered VA-source income and you will need to file a VA nonresident state income tax return to report this VA-source income only.
To determine the amount of VA-source income (if any), you can allocate your total wage income to the amount of days working remotely from WA (WA-source income) and the days that you worked in VA (VA-source income).
VA nonresident filing requirements -
But if your federal adjusted gross income (AGI) is more than the VA AGI filing requirement (which may be the case in your circumstances) and you have any VA-source (non-military) income, you will be required to file a VA nonresident state income tax return.
So according to the VA Department of Revenue, you will have a VA nonresident filing requirement if your income is
- Single, and Virginia adjusted gross income is $11,950 or more
- Married, filing a joint or combined return, and total Virginia adjusted gross income for both spouses is $23,900 or more
- Married, filing a separate return, and Virginia adjusted gross income is $11,950 or more
Virginia adjusted gross income is your federal adjusted gross income (from your federal income tax return) plus any Virginia additions, minus the Age Deduction and any Virginia subtractions. Virginia adjusted gross income does not include standard or itemized deductions, the child and dependent care expense deduction, personal exemptions or other deductions from income.
Nonresidents with income from Virginia sources are subject to the same filing requirements as residents. This means that the filing threshold for a nonresident is determined by Virginia adjusted gross income computed as a resident, including income from all sources. The filing threshold for a nonresident cannot be based solely on income from Virginia sources.
