Q: What is the City of Delaware income tax rate?
A: The income tax rate is 1.85 percent.

Q: Am I required to file an annual Delaware tax return?
A: Resident individuals and resident businesses must file an annual return, even if no tax is due.  Non-resident individuals who have income earned in Delaware that is not subject to employer withholding must file an annual return.  Non-resident individuals and non-resident businesses who conduct business in Delaware must file an annual return even if no tax is due.

Q: When is the annual Delaware tax return due?
A: The Delaware tax return is due on or before April 15 each year.  For business taxpayers, the return is due on or before the 15th day of the fourth month after the fiscal year ends.  Returns postmarked after the due date are subject to a late filing penalty.  Penalty information appears below. If the due date should fall on a weekend or holiday, the due date will move to the next business day.

Q: How do I file an extension?
A: For taxpayers on a federal extension, a separate request for a municipal extension is not required. Submit a copy of the federal extension with the filing of the municipal return.  For taxpayers not on a federal extension, an extension request must be submitted on or before the date the municipal return is due.  Please remember that an extension only extends the time allowed to file an annual return, not the time allowed for payment.

Q: Is any credit given if I pay tax to another city?
A: Yes. A partial credit is given to Delaware resident individuals for taxes paid to another city. The credit is the lesser of .50 of the tax paid to the other city, or .00925 of the income taxed by the other city and Delaware. W-2s or copies of the other city’s tax return and proof of payment must support credit claimed.

Q: What type of income is taxable?
A: For individuals, taxable income generally includes wages and net profit from business activities including pass through income. For a complete list of taxable versus non-taxable income click here.

Q: Do I need to file a declaration of estimated tax or make estimated tax payments?
A: Every taxpayer who anticipates having taxable income subject to Delaware income tax, and estimates their tax liability to be $200 or more after excluding Delaware withholding and/or other credits, must file a declaration of estimated tax and make estimated tax payments.  These payments are due quarterly on April 15, June 15, September 15 and January 15 (December 15 for business taxpayers).  Estimated tax payments received after these dates will be subject to penalty and interest.  Penalty and interest rates appear below.

As Monthly Interest Rate





7.0 %




2020 7.0 % .58%

Interest is imposed on all unpaid income tax, unpaid estimated income tax and unpaid employer withholding tax. The interest rate to be applied each calendar year is the federal short-term rate, rounded to the nearest whole number percent, plus five percent. The rate applies for the calendar year next, following the July of the year in which the federal short-term rate is determined under Section 1274 of the Internal Revenue Code.  Interest is charged for each month (or fraction of a month) that the tax remains unpaid.

Q: Can a penalty be imposed?
A: Yes. A late filing penalty can be imposed at the rate of $25 per month (or fraction of a month) that a return, other than an estimated income tax return, remains unfiled. This late filing penalty applies regardless of the liability on the return. The late filing penalty cannot exceed $150 for each failure to timely file. Tax filings and tax payments related to tax years beginning before January 1, 2016 are subject to the penalty and interest rates and late filing penalties imposed in Chapter 191 of Delaware’s Codified Ordinance, regardless of the date of filing or payment. State of Ohio laws governing interest and penalties can be found here.

Q: How can I file an appeal?
A:  A finding that you have underpaid tax, or charging you penalty and/or interest, may be appealed in writing to the City of Delaware income tax administrator.  The appeal should include your name, address and tax year/amount assessed.  Taxpayers must show in their appeal why the assessment should be deemed incorrect or unlawful.  Appeals can be emailed here.  State of Ohio Laws governing appeals can be found here.

Q: How can I pay my taxes?
A:  Tax payments can be mailed to the tax department at PO Box 496, Delaware, Ohio, 43015.  Tax payments can be made by credit card or e-check through our third-party service provider, Official Payments, by clicking here.  Please note that Official Payments charges a service fee for payment processing. Taxes can be paid in person by cash, check or money order in the tax department at City Hall, 1 S. Sandusky Street.

Q: What if I can’t pay my taxes?
A:  If you are unable to pay the full amount showing due on your tax return, file your return by April 15 and pay as much of the tax as possible.  You will then receive a bill for the remaining balance due, including applicable penalty and/or interest charges.  If you are still unable to pay the balance due in full, you may request an installment plan.   Taxpayers whose accounts are in good standing may be granted an installment plan via ACH debit of their checking or savings account.  To request an installment plan email the tax department here.
