If you’re required to make estimated tax payments and your 2019 California adjusted gross income is more than:

• $150,000
• $75,000 if married/RDP filing separately

Then you must base your estimated tax based on the lesser of:

• 90% of your tax for 2020
• 110% of your tax for 2019 (including alternative minimum tax)

This rule does not apply to farmers or fishermen.

Example:

Mrs. Smith’s tax liability was:

• $5,000 in 2020 (current year). 90% is $4,500
• $3,000 in 2019 (prior year). 110% is $3,300

Since the prior year amount is less than the current year, Mrs. Smith must pay at least $3,300 in 4 payments.

High income estimated tax

If your 2020 California adjusted gross income is equal to or greater than:

• $1,000,000
• $500,000 if married/RDP filing separately

You must pay your estimated tax based on 90% of your tax for 2020.

Example:

Mr. and Mrs. Grant’s 2020 joint AGI was $1,250,000. Their tax liability was:

• $127,518 in 2020 (current year). 90% is $114,766
