Common California 1099 Tax Mistakes
Not Paying Quarterly to CA
Many pay federal quarterly taxes but forget state. CA penalties add up fast — calculate and pay both.
Using Federal Standard Deduction for CA
CA standard deduction is MUCH lower ($5,363 vs $14,600). You may need to itemize for CA but not federal.
Forgetting the $800 LLC Fee
Catches new LLC owners off guard. Not prorated — full $800 even if formed in December. Due even with $0 income.
Deducting State Taxes on State Return
Can't deduct CA taxes on your CA return. Common confusion from federal return habits.
Not Registering with FTB
Must register if doing business in CA, even if based elsewhere but have CA clients. Penalties for late registration.

Some California cities impose additional business taxes on top of state taxes:
San Francisco
- Gross receipts tax: 0.38% - 0.65%

- Even for home-based businesses
Los Angeles

- Check with city clerk for requirements
Tip:Always check with your city clerk's office for specific requirements. Many cities require business registration even for home-based freelancers.
