Key insights
Safe-harbor protection
To avoid the underpayment penalty: pay at least 90% of your CURRENT-year tax OR 100% of your PRIOR-year tax (110% if your AGI was over $150K). Whichever is lower.
Quarters aren't equal
Q1 covers Jan-Mar (3 months), Q2 covers Apr-May (2 months), Q3 covers Jun-Aug (3 months), Q4 covers Sep-Dec (4 months). Despite this, IRS expects ~25% each quarter unless you use the annualized income method.
Pay via IRS Direct Pay
IRS.gov → Direct Pay → "Estimated Tax" → Form 1040-ES. Free, no signup, takes 2 minutes per quarter.
Recommended actions(4)

Open a separate "tax savings" bank account
High priorityTransfer 25-30% of every client payment the day it arrives. By each quarterly due date, the money is already there waiting.
Impact: Eliminates the "I spent it already" trap that most freelancers hit.
Use the annualized income method if income is uneven
Medium priorityForm 2210 Schedule AI lets you pay quarterly tax based on income earned IN THAT QUARTER instead of dividing annual evenly. Saves cash flow if your income is back-loaded.
