As per the IRS - Taxes must be paid as you earn or receive income during the year, either through withholding or estimated tax payments. If you don’t pay enough tax through withholding and estimated tax payments, you may be charged a penalty. You also may be charged a penalty if your estimated tax payments are late, even if you are due a refund when you file your tax return.
Individuals, including sole proprietors, partners, and S corporation shareholders, generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed.
Corporations generally have to make estimated tax payments if they expect to owe tax of $500 or more when their return is filed.
