Instructions for Form FTB 5805
Underpayment of Estimated Tax by Individuals and Fiduciaries
General Information
A Purpose
Use form FTB 5805 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.
The Franchise Tax Board (FTB) can figure the
amount of any penalty for you and send you a bill
after you have filed your return. If the FTB figures
your penalty and sends you a bill, you must pay
the penalty within 15 days of the billing to avoid
additional interest charges.
Important: If you answered “Yes” to any of the
questions in Part I (estates and trusts, see
General Information E), you must complete this
form and attach it to the front of your return.
C Waiver of the Penalty
You may request a waiver of the penalty if:
• You underpaid an estimated tax installment
due to a casualty, disaster, or other unusual
circumstance and it would be inequitable to
impose the penalty; or
• You retired after age 62 or became disabled in
1998 or 1999 and your underpayment was
due to reasonable cause.
To request a waiver:
• 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;
• Complete form FTB 5805 through Part II,
line 12 (Worksheet II, line 15 if you use the
regular method) without regard to the waiver.
Write the amount you want waived in
parenthesis on the dotted line next to Part II,
line 13 (Worksheet II, line 16 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 16 if you use the
regular method);
• Fill in the circle on Form 540, line 64;
Form 540NR, line 73; or Form 541, line 39;
and
• Attach form FTB 5805 to the front of your
return on top of any check, money order,
Form W-2, Form 1099, or other special
documentation.
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 2. Attach it to the front of your return on
top of any check, money order, Form W-2,
Form 1099, or other special documentation. Also
fill in the circle on your return for underpayment
of estimated tax.
E Estates and Trusts
Estates and trusts are required to make quarterly
estimated tax payments. 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 answered “Yes” to Question 4, complete
Part I only and attach form FTB 5805 to the
front of your return.
Note: 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 “Impor-
tant” on Side 1 of form FTB 5805.
G Farmers and Fishermen
You are considered a farmer or fisherman if at
least two-thirds (2/3) of your annual gross
income for 1998 or 1999 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, 2000. If
you file Form 540 or Form 541 and pay the entire
tax due by March 1, 2000, you do not owe a
penalty for underpaying estimated tax. Otherwise,
use form FTB 5805F, Underpayment of Estimated
Tax by Farmers and Fishermen, to figure your
penalty.
H Due Dates for Estimated
Tax Installments
If you are a calendar year taxpayer, the estimated
tax installment due dates for 1999 were:
• First quarter — April 15, 1999
• Second quarter — June 15, 1999
• Third quarter — September 15, 1999
• Fourth quarter — January 15, 2000
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.
If a due date falls on a Saturday, Sunday, or legal
holiday, use the next business day.
I Filing an Early Return in
Place of the 4th Installment
If you file your 1999 tax return by February 1,
2000, and pay the entire balance due, you do not
have to make your last estimate payment. Fiscal-
year filers must file their return and pay their tax
before the first day of the 2nd month after the end
of their taxable year.
J Amended Return
If you file an amended return:
• On or before the due date of your original
return, use the tax, credit and other amounts
shown on your amended return to figure your
penalty for underpayment of estimated tax.
• After the due date of the original return, you
must use the amounts shown on the original
return to figure the penalty.
K Penalty Rates
The rates used to determine the amount of your
penalty are established at various dates through-
out 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 1999 computation
period:
• 8% 4-15-99 through 6-30-99
• 7% 7-1-99 through 12-31-99
• 8% 1-1-00 through 6-30-00
Fiscal-year filers: the rates for the periods
7/1/00 through 12/31/00 and 1/1/01 through
3/15/01 will be determined by the FTB in
March 2000 and September 2000, respectively.
