SIDNEY — The city of Sidney, Revenue Collections Division, recently mailed postcards to all taxpayers in its database reminding them to file their 2015 income tax return (or extension request) no later than April 18, 2016.

This coincides with the due date for federal income tax returns. Failure to receive a postcard does not change the requirement to file, city officials said. All Sidney residents over the age of 18 are required to file a return (even those who had Sidney income tax withheld from their paycheck). If you lived in Sidney at any time during 2015 you are required to file a Sidney city tax return. If you had no income taxable to the city of Sidney you may be eligible to file an exemption form.

Individual tax forms may be obtained at the Sidney Library, Sidney post office, Revenue Collections at City Hall, 201 W. Poplar St., or by visiting the city’s website (www.sidneyoh.com – Tax Department page). The Revenue Collections office is open from 8 a.m. until 5 p.m., Monday through Friday, to assist taxpayers with Sidney tax return preparation at no charge. Additionally, the office will be open Saturday, April 9, from 8 a.m. until noon to assist those taxpayers who are unable to visit during normal office hours.

Generally, taxpayers who do not have 1.75 percent of Ohio municipal income tax withheld, or who have self-employment or net rental income, are required to make estimated tax payments or risk incurring underestimation or underpayment penalties. Payments are due as follows:

• For the 2015 tax year, estimated payments are due no later than Jan. 31, 2016.

• For 2016, affected taxpayers must pay quarterly estimated taxes by April 15, June 15, Sept. 15 and Dec. 15, 2016. This change was mandated in House Bill 5, approved by the state Legislature in late 2014.

Any taxpayer with questions is encouraged to visit the city’s website at www.sidneyoh.com – Tax Department page, email Jeffery Wical, income tax administrator, at [email protected] or call the city of Sidney, Revenue Collections Division, at 937-498-8111.
