                                            Instructions for Form BFC-160-A
Purpose of Form
Form BFC-160-A is used by corporations to determine whether they paid enough estimated tax, whether they are subject to an interest 
charge for underpayment of estimated tax, and if so, the amount of interest. Taxpayers with total gross receipts of less than $50 million 
should use this form.
How to Use This Form
Complete Part I of Form BFC-160-A to find out if you have an underpayment for any of the four payment periods. If you have an under-
payment on line 9 (column a, b, c, or d), go to Part II, Exceptions. If you cannot meet either of the exceptions for a payment period, go 
to Part III, Installment Interest Due. If you are using Form BFC-160-A either to calculate the interest on underpayment of estimated tax 
or to show that you qualify for any exception, attach Form BFC-160-A to Form BFC-1.
Part I – How to Calculate Your Underpayment
Complete lines 1 through 9 in Part I. The instructions for most of these lines are on the form itself. Follow the instructions below for the 
lines indicated.
Line 1 – Enter the total of line 6, page 1 of Form BFC-1.
Line 5 – Under the COVID-19 Fiscal Mitigation Act, the deadline for payments due April 15, 2020, was extended to July 15, 2020. 
If any of the installments were originally due April 15, enter July 15, 2020, at line 5 for that installment. The dates must be entered 
in chronological order. If the first and second installments were originally due April 15 and June 15, you must enter June 15 in 
column (a) and July 15 in column (b). 
Line 7b – Enter any overpayment shown on line 9 that is more than the total of all earlier underpayments.
Line 9 – If line 9 shows an underpayment, complete Part II to see if either of the exceptions apply.
Part II – Exceptions
You will not have to pay interest if all of your tax payments (line 10) were made on time and are equal to or more than either of the 
amounts calculated as explained by the exceptions (lines 11 and 12) for the same payment period (column a, b, c, or d).
Note: If at line 5, column (a) is June 15 and column (b) is July 15, make the following adjustments at lines 11 and 12:
Line 11 – Enter 50% of the tax in column (a) and 25% of the tax in column (b).
Line 12 – Enter 45% of the tax in column (a) and 22.5% of the tax in column (b).
Exception I – Tax Based on Prior Year’s Return Using Current Year’s Rates
This exception applies if the amount the corporation paid is equal to or more than the tax calculated by using the current year’s 
rates but based on the facts shown on the prior year’s return and the law that applies to the prior year. If the prior year return cov-
ered a period of less than a year, the prior return must be annualized by dividing the taxable net income by the number of whole 
months covered by the short period return and multiplying by 12.
Exception II – Tax Based on Annualized Tax
This exception applies if the estimated tax paid was equal to or more than 90% of the amount the corporation would owe if its es-
timated tax was based on a tax calculated from annualizing tax for the months preceding an installment date.
A corporation may annualize its tax as follows:
a.  For the first three months if the installment was required to be paid in the fourth month.
b.  For the first three months or for the first five months if the installment was required to be paid in the sixth month.
c.  For the first six months or for the first eight months if the installment was required to be paid in the ninth month.
d.  For the first nine months or for the first 11 months if the installment was required to be paid in the 12th month.
Note: Initial New Jersey S corporations should use the previous year BFC-1 income and the applicable CBT-100S rate.
a.  There is no rate of tax on entire net income that is not subject to federal corporate income taxation. All returns are subject to 
at least the minimum tax.
b.   The rate on taxable income that is subject to federal corporate income taxation is 6.5% (0.065) for taxpayers with entire net 
income of $50,000 or less. The rate is 7.5% (0.075) for those with entire net income greater than $50,000 but not greater than 
$100,000. For all others the rate is 9% (0.09).
Part III – Installment Interest Due
If no exception applies, complete lines 13 through 18.
A payment of estimated tax on or before any installment date is considered a payment of any previous underpayment only to the extent 
the payment is more than the amount of the current installment as figured on line 6. If the corporation made more than one payment for 
an installment, attach a separate computation for that installment.
Interest is calculated on the amount of the underpayment from the installment due date to the date of payment or the 15th day of the 
4th month after the close of the tax year, whichever is earlier. The annual interest rate is 3% above the average predominant prime rate 
and is imposed each month or part of a month the underpayment exists. Changes in the average predominant prime rate must be re-
flected in the interest calculation. The interest rates assessed by the Division of Taxation are published on the Division’s website.
The average predominant prime rate is the rate as determined by the Board of Governors of the Federal Reserve System, quoted by 
commercial banks to large businesses on December 1st of the calendar year immediately preceding the calendar year in which pay-
ment was due or as redetermined by the Director in accordance with N.J.S.A. 54:48-2.
