Investors & landlords

The IRS expects payment the same quarter you make the money. You will most likely need to make a Payment at that time. If you owe the IRS over $5,000 at tax time, you automatically receive penalties and interest for the substantial underpayment.

You may want to go through the estimated payments section of the program to help you prepare for the sale of the house.

You can make a payment to CO Payments | Department of Revenue - Taxation.

Great job planning ahead.
