Interest and Penalties
If you file your tax return or pay your tax after the due date, you may owe interest and penalties on the tax due.
Effective for tax years beginning on or after January 1, 2022, you may request a one-time abatement of a timeliness penalty if: (1) you were not previously required to file a California personal income tax return or have not previously been granted first-time abatement, (2) you have filed all required returns as of the date of the request for first-time abatement, and (3) you have paid, or are in a current arrangement to pay, all tax currently due.
Do not reduce the amount on line 97 or increase the amount on line 100 by any penalty or interest amounts. Enter on line 112 the amount of interest and penalties.
