Bowling Green City Income Tax: Filing, Credits, and Penalties

The Bowling Green city income tax is a flat 2.0% on qualifying wages and net profits for the 2025 tax year, and returns for that year are due April 15, 2026. A new rate took effect January 1, 2026, so if you are filing for the 2026 tax year, confirm the current percentage on the city’s Income Tax Division page before you calculate what you owe.¹

Who Has to File

Every Bowling Green resident age 18 or older must file a city return each year, even with no taxable income and even if an employer withheld the full tax.² Starting with tax year 2023, skipping the return triggers a flat $25 penalty regardless of whether you owe anything, so a zero-balance return is worth the few minutes.¹

Residents pay Bowling Green tax on all taxable income no matter where it is earned. Commute to Toledo or Findlay and the wages you earn there still count. Non-residents file on any taxable income earned within city limits, unless Bowling Green wages were their only local income and the tax was properly withheld.²

Businesses owe the tax too. Net profits of corporations from work performed in Bowling Green are taxable, as are the profits of partnerships and sole proprietors operating in the city, whether or not the owner lives there.²

What Is Taxed and What Is Not

The 2.0% rate applies to qualifying wages, which are generally the greater of Box 5 (Medicare wages) or Box 18 (local wages) on your W-2.³ That figure covers salaries, bonuses, commissions, and tips. Self-employed residents and business owners pay 2.0% on net profits after allowable business deductions.

Several common categories of income are exempt:⁴

Social Security, Medicare, pensions, and annuities
Interest, dividends, capital gains (except ordinary gains), and income from intangible property
Active-duty military pay and allowances
Insurance proceeds, workers’ compensation, unemployment compensation, and poor relief
Alimony, Section 125 cafeteria plan contributions, patent and copyright income (excluding oil and gas royalties), and Board of Elections poll worker pay under $1,000

One item that catches people off guard: supplemental unemployment benefits (sub pay) are taxable, not exempt.⁴ If you received sub pay during a layoff, include it on your return.

Credit for Taxes Paid to Another City

Residents who work in another Ohio municipality with its own income tax can claim a partial credit. It equals 50% of the lesser of the two rates, multiplied by the taxable income earned in the other city.⁵ For tax years beginning after January 1, 2026, the credit cannot exceed 1.075% of your Bowling Green taxable income.¹

The credit only offsets your Bowling Green liability. The city will not refund any excess, and if you work in a city with no income tax, there is no credit at all.

Quarterly Estimated Payments

If your Bowling Green tax after credits exceeded $200 in the prior year, you must file a Declaration of Estimated Income Tax and pay in quarterly installments.¹ This mostly affects self-employed residents, landlords, and anyone whose employer does not withhold Bowling Green tax.

Installments are due at the middle of the 4th, 6th, 9th, and 13th months of the tax year. For calendar-year filers, that means April 15, June 15, September 15, and January 15 of the following year.¹ Missing or underpaying an installment brings a 15% penalty on the shortfall plus 0.833% interest per month.⁶

Deadlines, Extensions, and How to File

Calendar-year filers submit the Bowling Green return on the same date the federal and Ohio returns are due. For tax year 2025, that is April 15, 2026.¹ Fiscal-year filers have three and a half months from the end of their fiscal year. On mailed returns, the postmark determines timeliness.

If you have a valid federal extension, Bowling Green honors it automatically; include a copy with your city return when you file. Without a federal extension, you must request a city extension in writing before the original due date.¹ An extension buys time to file, not time to pay. Anything you owe is still due April 15, and penalties and interest start running the day after.

The return is filed on Form R, which the same form is used by individuals, partnerships, and corporations.⁷ Include a copy of your federal Form 1040 and all W-2s. Attach the relevant federal schedules if you have self-employment or rental income.¹

You can file electronically through the city’s online portal and pay by check or credit card there, or you can mail a paper return with a check payable to the City of Bowling Green to the Income Tax Division at 305 N Main Street, Bowling Green, OH 43402.¹ Certified mail gives you a postmark receipt if timeliness is ever disputed.

Penalties and Interest for Late Filers

Penalties stack, and they add up quickly.

A flat $25 penalty for every late or missing return, even if you owe nothing.¹
A 15% penalty on any income tax not paid on time.⁸
A 15% penalty plus 0.833% monthly interest on estimated tax shortfalls.⁶
Interest of 1.5% per month or fraction of a month on all unpaid taxes until the balance is cleared.⁹

A resident who misses April 15 owing $500 would see a $75 late-payment penalty (15% of $500), plus $7.50 in interest for the first month, plus the $25 failure-to-file fee. Those charges keep growing every month the balance sits, so clearing any liability quickly saves real money.
