Third quarter estimated tax payments are due on September 15th. If you make estimated tax payments, make sure you have either mailed your payment in today (using certified mail, return receipt requested) or by paying electronically using EFTPS or your state’s electronic payment system.
A reminder that most Californians who make estimated payments do not have to make a state estimated payment today. California switched to a 30% – 40% – 0% -30% scheme for estimated payments. The third quarter payment is 0%. However, if you use the annualized income method (that is, you make estimated payments based on your year-to-date income), you may need to make a payment.
