If I am self-employed, or my employer does not withhold my taxes, must I file and make quarterly tax estimate payments?

Yes. Local earned income taxes are due quarterly and must be filed according to this schedule:

1st Quarter payment Due April 15

2nd Quarter payment Due July 15

3rd Quarter payment Due October 15

4th Quarter payment Due January 15

Any additional payment is due April 15 of the following year with your final return.

If a filing deadline falls on a weekend or state holiday, payment is due the next business day.

Keystone’s e-file is the easy way to report your quarterly tax estimates. You may schedule your payments in advance from your bank account.

Late-filed payments may be subject to statutory penalty, interest and costs.
