Understanding Estimated Tax Payments
If you're self-employed, a freelancer, or receive income without tax withholding, you may need to make quarterly estimated tax payments to avoid penalties.
The IRS expects you to pay at least 90% of your current-year tax liability or 100% of your prior-year liability (110% if AGI exceeds $150,000) through withholding and estimated payments.
