Stop Paying Estimated Taxes

I’ve paid estimated taxes the last few years, mainly to avoid larger tax bills come tax time, but also to help counter significant stock market gains. Our typical annual income is $400k+, but I expect it will be closer to $300k for 2020. My employer pays taxes for me in addition to extra with holdings I ask for at the state and federal level.

 

Question: Can I stop paying estimated taxes without facing a penalty?
