The Marion, Ohio income tax is a flat 2% on earned income, administered by the Income Tax Office inside the City Auditor’s Office. Every resident 18 or older has to file an annual return by April 15, even if no tax is owed, and non-residents who earn money working inside the city limits owe the 2% on that income too. One change worth flagging up front: under an ordinance passed March 23, 2026, the credit Marion gives residents for income tax paid to another city is now capped at 50% of that other city’s rate, which means commuters to higher-tax cities will owe Marion more than they used to.1City of Marion, OH. Income Tax
What the 2% Applies To
Marion taxes “qualifying wages” as defined under Ohio law, which tracks the federal wage definition: gross pay, salaries, commissions, bonuses, tips, and most other compensation reported by your employer.2Ohio Legislative Service Commission. Ohio Revised Code 718.01 – Municipal Income Tax Definitions Self-employment earnings and net business profits are taxed the same way. For residents, the 2% applies to qualifying wages earned anywhere. For non-residents, it applies only to income earned while physically working inside Marion.
Several common income types fall outside the tax. Interest, dividends, and capital gains are not subject to the municipal levy. Social Security benefits, pension distributions, and disability payments are also excluded. The tax reaches active earnings, not investment or retirement income.
Who Has to File
Marion is a mandatory-filing municipality. Every resident 18 and older has to submit an annual return, even if all your income comes from exempt sources like Social Security, and even if your employer already withheld the full 2%. A zero-liability return still has to be filed, and skipping it can trigger a late-filing penalty on its own.1City of Marion, OH. Income Tax
Non-residents who work in Marion have to file if their employer didn’t withhold the full 2% on the Marion-sourced portion of their pay. This commonly affects contractors, remote workers who occasionally report to a Marion office, and employees of companies based elsewhere. If your employer already withheld correctly, filing is still a good way to confirm nothing is outstanding.
If you moved into or out of Marion during the year, your taxable income is generally prorated for the portion of the year you were a resident. Income earned before you moved in, or after you left, is treated as non-resident income and is only taxed if it was earned inside the city.
Credit for Taxes Paid to Another City
Marion residents who work in another Ohio city that also imposes a municipal income tax can claim a credit on their Marion return for the tax paid to that other city. The credit is not dollar-for-dollar. Under the ordinance passed March 23, 2026, it’s capped at 50% of the other city’s tax rate.1City of Marion, OH. Income Tax
The math in practice: if you live in Marion and work in a city with a 2.5% income tax, you pay 2.5% to the work city. Marion’s credit is limited to half of that 2.5%, or 1.25%. Marion’s rate is 2%, so you still owe Marion the remaining 0.75%. Before the ordinance, the credit may have been more generous, so plan for a larger Marion bill if you commute to a higher-tax city. The credit only covers income earned while you were a Marion resident, and it isn’t available to non-residents.
Deadline and Extensions
The return for tax year 2025 is due April 15, 2026, matching the federal filing deadline.1City of Marion, OH. Income Tax When April 15 falls on a weekend or holiday, the deadline shifts to the next business day.
You can get a six-month extension to file. If you’ve already requested a federal automatic extension, Marion honors it automatically, moving your individual due date to October 15. If you haven’t filed for a federal extension, you can request a Marion-specific six-month extension from the tax administrator, provided the request arrives by April 15.3Ohio Legislative Service Commission. Ohio Revised Code 718.05 – Annual Return and Filing Extensions
An extension to file is not an extension to pay. If you expect to owe, you have to estimate the amount and send payment by the original April 15 deadline. Unpaid tax after that date accrues penalties and interest whether or not your filing extension is valid.
How to File and Pay
Before you start, pull together your W-2s from every employer (showing gross wages and any municipal tax withheld), any 1099-NEC or 1099-MISC forms for freelance or contract work, and the first page of your federal Form 1040. The Income Tax Office uses the federal return to reconcile what you report.
Marion publishes separate Individual and Business Income Tax Forms. You can download them from the city website or pick them up at the Income Tax Office on the third floor of City Hall.4City of Marion, OH. Current and Previous Year Forms On the individual return, enter the total qualifying wages from your W-2s plus any taxable 1099 income, then calculate the 2% liability. There’s a dedicated line for the credit for taxes paid to other cities. Work through that line carefully given the new 50% cap before you conclude you owe nothing.
You can submit the completed return in several ways:
- In person at the Income Tax Office on the third floor of City Hall during regular business hours.
- By drop box between the front doors of City Hall; mark the envelope clearly for the Income Tax Department.
- By mail to the Income Tax Office at the address printed on the form.
- By online payment through the city’s website, though the return itself may still need to be submitted another way.
Any balance due has to accompany the return. Checks and money orders should be made payable to the City of Marion Income Tax. A returned payment carries a $35 fee per item.5City of Marion, Ohio. Pay Income Tax
Quarterly Estimated Payments
If you expect to owe at least $200 to Marion after subtracting withholding and credits, Ohio law requires you to make quarterly estimated payments. This typically catches the self-employed, business owners, landlords with Marion rental income, and workers whose employers don’t withhold Marion tax.6Ohio Legislative Service Commission. Ohio Revised Code 718.08 – Estimated Taxes
The cumulative payment schedule for a calendar-year taxpayer is:
- April 15: 22.5% of the estimated annual liability
- June 15: 45% of the estimated annual liability
- September 15: 67.5% of the estimated annual liability
- December 15: 90% of the estimated annual liability
Payments are cumulative, so earlier installments count toward later thresholds. Business quarterly estimate coupons are available on the city website or at the Income Tax Office. Underpaying estimates can trigger a 15% penalty on the shortfall plus interest.
Business and Rental Income
Businesses operating in Marion owe the same 2% on net profits and have to register with the Income Tax Office and file an annual business return.1City of Marion, OH. Income Tax A business that operates both inside and outside Marion apportions net profit using a three-factor formula that averages the ratios of property, payroll, and gross receipts located in Marion against the business’s totals everywhere.7Ohio Legislative Service Commission. Ohio Revised Code 718.02 – Income Subject to Tax
Rental income from property located in Marion is taxed by Marion no matter where the landlord lives. If you’re a Marion resident who owns rental property in another city, that income is taxed both where the property sits and by Marion as your city of residence, with the credit above applied. Ohio law lets landlords use separate accounting rather than the three-factor formula when calculating net rental profit for a specific city.7Ohio Legislative Service Commission. Ohio Revised Code 718.02 – Income Subject to Tax
Penalties and Interest for Late Filers
Three charges can stack when you’re late:
- Late filing penalty of up to $25 per return for each month or part of a month the return is late, with a $150 maximum. Marion has to waive this penalty on your first late filing if you eventually submit the return.8Ohio Legislative Service Commission. Ohio Revised Code 718.27 – Penalty and Interest
- Late payment penalty of 15% of the tax not paid on time, applied to both regular income tax and estimated payments.8Ohio Legislative Service Commission. Ohio Revised Code 718.27 – Penalty and Interest
- Interest at the federal short-term rate (rounded to the nearest whole percent) plus 5%. For 2026, that works out to 9% per year, running on all unpaid tax including unpaid estimates.9Regional Income Tax Agency. Penalty and Interest Rates
These add up quickly. A filer three months late who owes $1,000 could face a $75 late-filing penalty, a $150 late-payment penalty, and 9% annual interest on the balance. Even if you can’t pay in full on April 15, filing on time removes one of the three charges.
Refunds and Overpayments
If you overpaid Marion income tax through excess withholding or estimated payments, you can request a refund from the tax administrator. The request has to be made within three years after the return was due or the tax was paid, whichever is later.10Ohio Legislative Service Commission. Ohio Revised Code 718.19 – Requests for Refunds Use the form the Income Tax Office prescribes and include documentation supporting the claim. If a refund request is denied in whole or in part, you’ll receive written reasons and instructions for appealing. Overpayments are especially common for people who moved out of Marion mid-year or had Marion tax withheld on work actually performed elsewhere, so it’s worth checking your W-2 against where you really worked.
