That's actually not the case, estimated tax is due quarterly (ex. for income in Q1 of 2016 for which your employer doesn't withhold taxes, you have to pay estimated tax by April 15, 2016).

But yeah, definitely talk to a CPA.

It looks like if you have at least 110% your previous year's tax withheld and don't have self employment income you do not need to pay quarterly taxes.

I can't find the actual IRS publication that says this, though.
