How to Make CA FTB Estimated Tax Payments Without Getting Penalized
You're required to make California estimated tax payments if
You expect to owe at least $500 in state taxes for the year ($250 if married/RDP filing separately)
Your withholding and credits are less than:
• 90% of this year’s tax liability, or
• 100% of last year’s tax liability (110% if your AGI is over $150,000, or $75,000 if married/RDP filing separately)
This usually applies to self-employed individuals, freelancers, independent contractors, and anyone with significant investment income.
TLDR;
You must make estimated tax payments if you expect to owe $500+ in CA state taxes.
Applies mostly to self-employed individuals, freelancers, and those with untaxed income.
CA’s payment schedule is uneven: 30% due in April, 40% in June, 0% in September, 30% in January.
Use FTB Web Pay to pay online, or mail Form 540-ES vouchers (less reliable).
Aim for the safe harbor rule: pay 90% of current year or 100–110% of last year’s tax to avoid penalties.
Don’t assume the Franchise Tax Board will remind you—track payments yourself.
Review and adjust your estimated payments if income changes mid-year.
Ask a pro if unsure—penalties cost more than a quick review.
| Quarter | Due Date | % of Estimated Tax Due |
|---|---|---|
| Q1 | April 15, 2025 | 30% |
| Q2 | June 16, 2025 | 40% |
| Q3 | Sept. 15, 2025 | 0% |
| Q4 | January 15, 2026 | 30% |
Note: If you file your 2025 return by January 31, 2026, and pay your full balance, you can skip the Q4 payment without penalty.

Conclusion
If you’re unsure how much to pay or when, don’t wing it. I tell every client: review last year’s tax return, track your current income, and keep a calendar for those deadlines. If it feels confusing, just ask. That call is cheaper than an FTB penalty.
Here’s my rule of thumb: check your numbers every quarter. If you're not sure, run it by someone. You’d be surprised how many people lose money just because they were afraid to ask a simple question. FTB penalties aren’t kind, but they are avoidable.
