Virginia safe harbor

Greetings, I recently moved to Virginia so I payed no 2018 income taxes to Virginia.  My only 2019 income attributable as a Virginia resident was in December 2019 when I converted funds from my IRA to my ROTH.

 

Do I need to pay a 4th Q estimated tax payment to Virginia by 1/15/20 - or - is 'safe harbor' in play since I owed no taxes in 2018 and I would just pay the Virginia taxes penalty free when I file my tax returns later this spring?

Thank you, Larry
