I did not do the reqired deposits for Q1 and Q2. What are the steps I need to take to get current?

You will need to make the payment for all 3 quarters on or before September 15th. You will be hit with the underpayment penalty for the first 2 quarters. If you can, I would suggest paying the taxes for the 2 quarters as soon as possible. Then make the remaining quarters payments on time.

The underpayment tax penalty is worked out by looking:

• How much you owed 
• How long it took before you finally paid
