2017 Instructions for Form FTB 5805
Underpayment of Estimated Tax by Individuals and Fiduciaries
Estimated Tax Payments – Taxpayers are required to pay 30% of the required annual payment for the first required installment, 40% of the required annual payment for the second required installment, no installment is due for the third required installment, and 30% of the required annual payment for the fourth required installment. For more information get the instructions for Form 540‑ES, Estimated Tax for Individuals, or Form 541-ES, Estimated Tax for Fiduciaries.
You must make estimated tax payments if you expect to owe at least $500 ($250 if married/RDP filing separately) in tax for 2017. If in the prior year your tax liability, less any credits for the prior year, was less than $500 ($250 for married/RDP filing separately) you are not subject to the underpayment of estimated tax penalty.
Taxpayers with California adjusted gross income (AGI) equal to or greater than $1,000,000 (or $500,000 if married/RDP filing separately), must use the tax on their 2017 tax return to figure their penalty if they are subject to the underpayment of estimated tax penalty.
The Mental Health Services Act, imposes an additional 1% tax on taxable income over $1,000,000 and is included in the calculation of the estimated tax.
Alternative Minimum Tax (AMT) is included in the calculation of estimated tax.
The underpayment of estimated tax penalty shall not apply to the extent the underpayment of an installment was created or increased by any provision of law that is chaptered during and operative for the taxable year of the underpayment. To request a waiver of underpayment of estimated penalty, follow the directions under General Information C.
Use form FTB 5805, Underpayment of Estimated Tax by Individuals and Fiduciaries, to see if you owe a penalty for underpaying your estimated tax and, if you do, to figure the amount of the penalty.
B. Who Must File
Generally, you do not have to complete this form. If you owe a penalty, the Franchise Tax Board (FTB) figures the penalty for you and sends you a bill after you have filed your tax return. You must pay the penalty within 15 days of the billing to avoid additional interest charges.
Important: If you answer “Yes” to any of the questions in Part I (estates and trusts, see General Information E), complete this form and attach it to the back of your tax return.
C. Waiver of the Penalty
You may request a waiver of the penalty if either one of the following apply:
- You underpaid an estimated tax installment due to a casualty, disaster, or other unusual circumstance and it would be inequitable to impose the penalty.
- You retired after age 62 or became disabled in 2016 or 2017 and your underpayment was due to reasonable cause.
To request a waiver do all of the following:
- Check “Yes” on form FTB 5805, Part I, Question 1, and in the space provided, explain why you are requesting a waiver of the estimate penalty. If you need additional space, attach a statement. Be sure to include your name and tax ID number to any statement you attach.
- Complete form FTB 5805 through Part II, line 12 (Worksheet II, line 11 if you use the regular method) without regard to the waiver. Enter the amount you want waived in parentheses on the dotted line next to Part II, line 13 (Worksheet II, line 12 if you use the regular method). Subtract this amount from the total penalty you figured without regard to the waiver, and enter the result on Part II, line 13 (Worksheet II, line 12 if you use the regular method).
- Check the box on Form 540, line 113; Long Form 540NR, line 123; or Form 541, line 44.
- Attach form FTB 5805 to the back of your tax return.
D. Annualized Income Installment Method
If your income varied during the year and you use the annualized income installment method to determine your estimate payment requirements, you must complete form FTB 5805, including Side 3. Attach it to the back of your tax return. Also check the box on Form 540, line 113; Long Form 540NR, line 123; or Form 541, line 44 for the underpayment of estimated tax.
E. Estates and Trusts
Estates and grantor trusts, which receive the residue of the decedent’s estate, are required to make estimated income tax payments for any year ending two or more years after the date of the decedent’s death. If you answer “Yes” to Question 4, complete Part I only and attach form FTB 5805 to the back of your tax return.
Exempt trusts should use form FTB 5806, Underpayment of Estimated Tax by Corporations.
F. Nonresidents and New Residents
The penalty for the underpayment of estimated tax applies to nonresidents and new residents. See the conditions listed in the box labeled “Important” on Side 1 of form FTB 5805.
In 2001, California changed the method used to calculate loss carryovers, deferred deductions, and deferred income for nonresident and part‑year resident taxpayers (AB 1115, Stats 2001, Ch. 920). This law changed the tax computation to recognize those items, and established a new method of determining percentages for computing tax for all nonresidents and part-year residents. California changed the nonresident tax forms (Long and Short Form 540NR) to more clearly show that nonresidents are taxed by California only on their California taxable income. For more information get FTB Pub. 1100, Taxation of Nonresidents and Individuals Who Change Residency.
California law is compatible with the Servicemembers Civil Relief Act (Public Law 108‑189). This means that servicemembers domiciled outside of California, and their spouses/RDPs, may exclude the servicemember’s military pay from gross income when computing the tax rate on nonmilitary income.
G. Farmers and Fishermen
You are considered a farmer or fisherman if at least two-thirds (2/3) of your annual gross income for 2016 or 2017 is from farming or fishing. Farmers and fishermen are required to make one estimate payment. For calendar year taxpayers, the due date is January 15, 2018. If you file Form 540, Long Form 540NR, or Form 541 and pay the entire tax due by March 1, 2018, you do not owe a penalty for underpaying estimated tax. Use form FTB 5805F, Underpayment of Estimated Tax by Farmers and Fishermen.
H. Due Dates for Estimated Tax Installments
If you are a calendar year taxpayer, the estimated tax installment due dates for 2017 were:
- First payment — April 15, 2017
- Second payment — June 15, 2017
- Third payment — September 15, 2017
- Fourth payment — January 15, 2018
Fiscal year filers must pay estimated tax installments on the 15th day of the 4th, 6th, and 9th months of their fiscal year, and the 1st month of the following fiscal year.
The penalty is figured separately for each due date. Therefore, you may owe a penalty for an earlier installment due date, even if you pay enough tax later to make up the underpayment.
When the estimate due date falls on a weekend or holiday, the deadline to file and pay without penalty is extended to the next business day.
I. Filing an Early Return in Place of the 4th Installment
If you file your 2017 tax return before February 1, 2018, and pay the entire balance due, you do not have to make your last estimate payment. Fiscal year filers must file their tax return and pay their tax before the first day of the 2nd month after the end of their taxable year.
J. Amended Tax Return
If you file an amended tax return:
- On or before the due date of your original return, use the tax, credit, and other amounts shown on your amended tax return to figure your penalty for underpayment of estimated tax.
- After the due date of the original tax return, you must use the amounts shown on the original tax return to figure the penalty.
K. Penalty Rates
The rates used to determine the amount of your penalty are established at various dates throughout the year. If an installment of estimated tax for any quarter remained unpaid or underpaid for more than one rate period, the penalty for that underpayment will be figured using more than one rate when applicable.
The following rates apply to the 2017 computation period:
- 4% 4-15-17 through 4-15-18
Fiscal year filers: the rates for the periods July 1, 2018 through December 31, 2018 and January 1, 2019 through June 30, 2019 will be determined by the FTB in March 2018 and September 2018, respectively.
Call the FTB’s automated phone service to get updated penalty rates. Call the number below, and follow the recorded instructions. Enter code number 403 when instructed.

Specific Line Instructions
Part II – Computing the Required Annual Payment
Use this part to figure the amount of estimated tax that you were required to pay.
Certain high-income taxpayers are required to use 110% (instead of 100%) of the tax shown on their previous year’s return in the computation of the required annual payments. See the instructions for line 5.
Line 1 – Enter your 2017 tax liability from the following (excluding tax on lump-sum distributions and accumulation distribution of trusts):
- Form 540, add line 48, line 61, line 62, and any Internal Revenue Code (IRC) Section 453A interest from line 63, less the amount on line 74.
- Long Form 540NR, add line 63, line 71, line 72, and any IRC Section 453A interest from line 73, less the amount on line 84.
- Form 541, line 28.
Line 3 – Enter the 2017 amounts from the following:
- Form 540, line 71 and line 73.
- Long Form 540NR, line 81 and line 83.
- Form 541, line 29 and line 31.
Line 5 – Enter your 2016 tax liability from the following (excluding tax on lump-sum distributions and accumulation distribution of trusts):
- Form 540, add line 48, line 61, line 62, and any IRC Section 453A interest from line 63, less the amount on line 74.
- Long Form 540NR, add line 63, line 71, line 72, and any IRC Section 453A interest from line 73, less the amount on line 84.
- Form 541, line 28.
If the California adjusted gross income (AGI) shown on your 2016 California tax return is more than $150,000, or more than $75,000 if married/RDP filing a separate tax return, then enter 110% (1.10) of the tax liability from your 2016 tax return on line 5.
If the California AGI on your 2017 tax return is equal to or greater than $1,000,000/$500,000 if MFS, enter 90% (.90) of the tax liability from your 2017 tax return on line 5.
If you did not file a tax return for 2016, or if your 2016 taxable year was less than 12 months, do not complete line 5. Instead, enter the amount from line 2 on line 6. (If your California AGI is equal to or greater than $1,000,000/$500,000 for married/RDP filing separately, use line 2.
You may use the short method only if you are a calendar year taxpayer and either one of the following apply:
- You made no estimated tax payments or your only payments were California income tax withheld.
- You paid estimated tax on the required due dates.
If any payment was made earlier than the due date, you may use the short method, but using it may cause you to pay a larger penalty than using the regular method. If the payment was only a few days early, the difference is likely to be small.
You may not use the short method if either of the following apply:
- You made any estimated tax payment late.
- You answered “Yes” to Part I, Question 3.
If you can use the short method, complete Part II, line 1 through line 10 to figure your total underpayment for the year, and line 11 through line 13 to figure the penalty.
Part III – Annualized Income Installment Method
If your income varied during the year, you may be able to lower or eliminate the amount of one or more required installments by using the annualized income installment method. Use Part III to figure the required installment amount to enter on Worksheet II, Regular Method to Figure Your Underpayment and Penalty, line 1 (page 4).
Complete line 1 through line 16 to figure your current year tax, per quarter, based on your income as you earned it. Then, complete line 17 through line 23 to figure your required installment for each quarter. (The total of all amounts entered on line 23 should equal the amount from Part II, line 6.)
If you use the annualized income installment method for any payment due date, you must use it for all payment due dates. To figure the amount of each required installment, Part III automatically selects the smaller of the annualized income installment or the regular installment (increased by the amount saved by using the annualized income installment method in figuring earlier installments).
If you are filing Long Form 540NR, see Long Form 540NR Instructions for Part III at the end of this section.
Line 1 – Figure your total income minus your adjustments to income for each period from
January 1, 2017 to the ending date of each period (the amounts are cumulative). Include your share of partnership or S corporation income or loss items for the period.
Line 2 – Form 541 filers. Do not use amounts shown in column (a) through column (d). Instead, use 6, 3, 1.71429, and 1.09091, respectively, as the annualization amounts.
Line 6 – Multiply line 4 by line 5 and enter the result on line 6. Your annualized itemized deductions are limited if, in any quarter, federal annualized income (use Federal Annualized Income Worksheet below) is greater than:
- $374,411 (married/RDP filing jointly or qualifying widow(er)).
- $187,203 (single or married/RDP filing separately).
- $280,808 (head of household).

Instructions for Worksheet II – Regular Method to Figure Your Underpayment and Penalty
Part I — Figure Your Underpayment
Line 1 – Enter in column (a) through column (d) the amount of your required installment. For most taxpayers, this is the amount shown on form FTB 5805, Side 2, Part II, line 6 multiplied by 30% for column a and column d, enter -0- in column c, and 40% for column b. If you use the annualized income installment method, enter the amounts from form FTB 5805, Side 3, Part III, line 23.
Line 2 – Enter the estimate payments made by the date at the top of each column.
Include in column (a) any overpayment of tax from your 2016 tax return that you elected to apply to the 2017 estimated tax.
Enter in column (a) and column (d) the result of the amount shown on form FTB 5805, Part ll, line 3 multiplied by 30%, enter -0- in column (c) and 40% for column (b).
For withheld California income tax, you are considered to have paid the required amounts on each payment due date unless you can show otherwise. If you can show that your California withholding was otherwise withheld, answer “Yes” to Part I, Question 3 and enter the uneven amounts withheld on the lines provided on Part I, Question 3.
If you file your tax return and pay the tax due before February 1, 2018, enter the amount of tax paid with your tax return in column (d). In this case, you will not owe a penalty for the estimate payment due by January 15, 2018.
Line 8 – If line 8 is zero for all payment periods, you do not owe a penalty. But if you answer “Yes” for any question on form FTB 5805, Side 1, Part I, you must file form FTB 5805 with your tax return.
Part II — Figure the Penalty
Figure the penalty by applying the appropriate rate against each underpayment shown on line 8. The penalty is figured for the number of days that the underpayment remained unpaid.
The rates are established at various times throughout the year. If an underpayment remained unpaid for more than one rate period, the penalty on that underpayment will be figured using more than one rate period.
Use line 10 to figure the number of days the underpayment remained unpaid. Use line 11 to figure the actual penalty amount by applying the rate against the underpayment for the number of days it remained unpaid.
Maximum days in a rate period per quarter:
Installment – Days in Rate Period
1 – 365
2 – 304
3 – 212
4 – 90
Payment Application. Your payments are applied to any underpayment balance on an earlier installment. It does not matter if you designate a payment for a later period.
Example: You had an underpayment for the April 15th installment of $500. The June 15th installment required a payment of $1,200. On June 10th, you sent in a payment of $1,200 to cover the June 15th installment. However, $500 of this payment is considered to be for the April 15th installment. The penalty for the April 15th installment is figured to June 10th. The amount of the payment to be applied to the June 15th installment is $700.
Subsequent Payments. For purposes of computing the penalty, it may be helpful to make a list of any payments that you made after the timely payments entered in Part I, line 2. If you made no other payments, follow the line-by-line instructions for Part II.
If you made subsequent payments, you may need to make additional computations for the applicable column on the worksheet. However, if the payment reduced the underpayment to zero, there are no further computations to make for that column. In that case, you count the number of days from the installment due date to the date paid.
If a subsequent payment does not reduce the underpayment to zero, you will need to make an additional computation in the column.
- First, count the number of days from the due date to the date paid and use the underpayment amount from Worksheet II, line 8.
- Second, count the number of days from the payment date to the end of the rate period, and subtract the amount of the subsequent payment from the underpayment amount from Worksheet II, line 8.
- Third, apply the rate for the applicable period.
Worksheet II – Regular Method to Figure Your Underpayment.
|Part 1: Figure Your Underpayment||Payment Due Dates|
|1. Required Installments. See instructions|
|2. Estimated tax paid and tax withheld. See instructions. For column (a) only, also enter the amount from line 2 on line 6. (If line 2 is equal to or more than line 1 for all payment periods, stop here; you do not owe the penalty. Do not file form FTB 5805 unless you answer “Yes” to a question in Part I)|
|COMPLETE LINE 3 THROUGH LINE 9 OF ONE COLUMN BEFORE GOING TO THE NEXT COLUMN.|
|3. Enter amount, if any, from line 9 of previous column||Not Applicable|
