Instructions for Form CBT-150 — Estimated Tax Voucher

CBT-150 2026

# Who Must File

Taxpayers whose prior year tax liability is greater than $1,500 must make four 25% estimated tax payments in the fourth, sixth, ninth, and 12th months of its accounting period towards the current year's tax, except for taxpayers with gross receipts of $50 million or more for the prior privilege period must make installment payments as follows: 25% in the 4th month, 50% in the 6th month, and 25% in the 12th month. A taxpayer whose prior year tax liability is $1,500 from CBT-100, CBT-100U, or CBT-100S, may, in lieu of making these estimated tax payments, make a single estimated tax payment of 50% of the prior year's tax liability. This option must be made and the 50% payment must be remitted no later than the original due date of the prior year's tax return.

# Electronic Filing Mandate

All taxpayers and tax preparers must file Corporation Business Tax returns and make payments electronically.
This mandate includes all estimated payments. Visit the Division's website or check with your software provider to see if they support these filings.

# How to Determine Your Estimated Tax

Computation of the estimated tax must be made on the basis of a full accounting period. Taxpayers determine their expected liabilities on the basis of circumstances existing at the time prescribed for filing. Use the estimated tax worksheet on page 3 or 4, whichever is applicable, for computing each installment due.

# Estimated Tax Worksheet

A worksheet is provided to assist in computing the amounts of installment payments due for any taxpayer required to file a statement.

# CBT-100U, or CBT-100S

If the prior year's return is overpaid and the taxpayer elected to apply that overpayment as a credit to the current tax year, take credit for that amount when calculating the estimated payments. However, if the taxpayer elected to have any portion or all of the overpayment on the prior year's return refunded, this amount cannot be claimed as a credit.

# Calendar Year and Fiscal Year Taxpayers

All taxpayers should enter the appropriate tax year to which the remittance should be credited. Fiscal year taxpayers must also enter the beginning and ending dates of their accounting period.

# Underpayment of Estimated Tax

Any taxpayer who is required to file a statement of estimated tax must file each estimate together with remittance covering the estimated tax due on the required due date. Failure to remit such estimated payment or making an underpayment of such tax or any installment thereof, will result in the imposition of interest at an annual rate of 3% above the average predominant prime rate for each month or part of a month that the underpayment exists. The average predominant prime rate to be used 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 the payment was due or as redetermined by the Director in accordance with N.J.S.A. 54:48-2. The interest rates assessed by the Division of Taxation are published on the Division's website.
In general, a taxpayer will be considered as having underpaid if the total amount of the estimated tax payments for the tax year are less than 90% of the total tax liability reported on the current year's tax return and less than 100% of the total tax liability reported on the prior year's tax return. The addition to the tax on any underpayment of any installment payment is computed on form CBT-160-A or CBT-160-B, whichever is applicable, and must be paid with the return.

# When to File

The appropriate estimated tax payment due dates for both calendar and fiscal year taxpayers can be found in the Calendar of Due Dates on page 2.
