We are residents of Florida and had a vacation home in Massachusetts. We have not filed a state income tax return in Massachusetts in over 15 years, but we will owe them a capital gain tax of around $10,000. Do we need to file a return for 2021 or is there a just a form to send them and when does it need to get done. We also will owe the IRS around $30,000. Do we need to add this to our next quarterly payment in September or can we wait till we file our 2021 return in April?
