Retired Individuals

Social Security and other forms of retirement and permanent disability incomes are not taxable. However, retired and disabled persons with other sources of income must file and pay tax on those other sources of income.

Residents who are 60 years and older may qualify for an exemption of the mandatory filing requirement. Please contact our office for further information.


Losses resulting from businesses and rentals can not be used to off-set taxable income excluding W2 income. Losses can be carried forward for five years.

Part-year Residents

You will only be taxed on the income received after the date that you moved to your municipality. When filing your first return it will be necessary to attach both your W-2 and a year to date pay statement (provided by your employer), as of the beginning date of your residency.

Employee Withholding Requirements

All employers who have employees working inside the City of St. Marys are required to withhold the tax on the Medicare wage base. There are no allowances made for any type of deferred compensation. Employee contributions to retirement plans, stock options, etc., are all taxable.

Remittance of the tax is due on a quarterly basis if the tax withheld is less than $200 per month or $2,400 per year. Returns and payments are due on April 30, July 31, October 31, and January 31.
