Quarterly Taxes California 2026: What Freelancers & Gig Workers Need to Know

What Are Quarterly Taxes?

Quarterly taxes (also called estimated taxes) are payments made four times per year instead of paying everything at once during tax season.

They apply to income that is not automatically taxed, such as:

• freelance income
• business income
• gig work (Uber, DoorDash)
• online sales (Etsy, Amazon, Shopify)
• rental or Airbnb income
• content creation (YouTube, TikTok, affiliate income)

How Quarterly Taxes Work

Instead of waiting until April, you estimate your yearly income and pay taxes in four installments.

The total tax includes:

• federal income tax
• self-employment tax (approximately 15.3%)
• California state income tax

You divide your estimated yearly tax into four payments.

California State Tax Explained

California has a progressive income tax system, with rates ranging from 1% up to 13.3%.

This means:

• higher income leads to higher tax rates
• California taxes are significantly higher than in states like Texas or Florida

Because of this, quarterly tax planning is especially important for California residents.
