Estimated taxes are quarterly payments made to the IRS by individuals who receive income not subject to withholding, such as self-employment income, freelance earnings, investment income, or rental income. These payments cover income tax and self-employment tax throughout the year.
You must pay estimated quarterly taxes if you expect to owe at least $1,000 in tax when your return is filed and your withholding and refundable credits are less than the smaller of: 90% of your current year tax, or 100% of your previous year tax (110% if your AGI was over $150,000).
