No. If you no longer have income from an occupation, or net profits from a business, or if your income from an occupation or net profits from a business is below $10,000, you may be exempt from the tax. To receive an exemption from the occupation tax, you must notify the Chester County Assessment Office in writing no later than September 1. The Assessment Office will notify Keystone, which will issue an adjusted bill, if applicable.
Even if you are retired, you still owe the per capita tax.
