Simple answer: No. It is not mandatory to pay quarterly taxes.  


But, you want to make a payment to avoid an underpayment penalty. You should make estimated tax payments for the current tax year if both of the following apply:
- 1. You expect to owe at least $1,000 in tax for the current tax year, after subtracting your withholding and credits. 
- 2. You expect your withholding and credits to be less than the smaller of: 90% of the tax to be shown on your current year’s tax return, or  100% of the tax shown on your prior year’s tax return. (110% if your income will be more than $150K) . Your prior year tax return must cover all 12 months.


If your goal is just to avoid the underpayment penalty, then paying 100% of the prior year tax liability is the “safe haven”.  You might be able to increase your W2 withholding, at your regular job, to account for the extra income.
