FAQ
Estimated Payments
1. Do I need to make estimated payments?

The City Tax Act requires that a person must make quarterly estimated payments if the person's income tax liability, after credits, will be $100 or more for the year.  If you are required to make estimated payments use form 5123.

Special note for people required to file estimates. You may owe penalty and interest for underpayment, late payment or for failing to make estimated tax payments.

For more information view form 5123 instructions.

2. When are estimated tax payments due?

Quarterly tax payments are due April 17, 2018, June 15, 2018, September 17, 2018 and January 15, 2019.

3. What happens if I fail to file and make the required estimated tax payments?

Failure to file and make the required estimated tax payments may result in an assessment issued by the City Income Tax Administration for penalty and interest.

Penalty is 10 percent of underpaid tax per quarter or 25 percent for failing to file estimated payments. Interest is 1 percent above the prime rate.

4. Why am I being charged penalty and interest?

The City Income Tax Administration follows the City Tax Act guidelines for estimated tax requirements. To avoid penalties for failure to make estimated tax payments, your total tax paid through credits and withholding must be 70 percent of your current year tax or 70 percent of your prior year tax.

Penalty is 25 percent of the tax due for failing to file estimated payments or 10 percent for failing to pay enough with your estimates, or paying late.

Interest is 1 percent above the adjusted prime rate.
