Your books have to carry each one separately. Most states stop at a state income tax. Ohio adds a city layer, and it is not a small one. A practice in Ohio owes net profit tax to the city where it operates, withholds tax from every paycheck for the city where the work happens, and files on a calendar that runs all year. Each city sets its own rate, its own credit rules and, in many cases, its own administrator. None of it is hard once you see the structure. All of it gets expensive when the books are not built for it. Here is the structure, and what it requires of your books. ## Why Ohio Is Different From Every Other State Ohio lets its cities and villages levy their own income tax under [Chapter 718 of the Ohio Revised Code](https://codes.ohio.gov/ohio-revised-code/chapter-718), and hundreds of them do. The tax reaches two things: wages earned by people who work inside the city, and the net profit of businesses that operate there. A dental practice has both. That is the part owners underestimate. The city tax is not a version of the state return. It is a separate tax with a separate return, separate payments, separate registrations and, for your team, a separate withholding line on every paycheck. It sits on top of your federal and state obligations. It never replaces them. It also never stops. Net profit tax runs on quarterly estimates. Withholding runs monthly for most practices. There is an annual return for the business and an annual reconciliation for payroll. A practice that thinks about city tax once a year, in April, is a practice that pays penalties. ## The 600+ Jurisdictions Problem The Ohio Department of Taxation's [2025 annual report](https://dam.assets.ohio.gov/image/upload/v1768508046/tax.ohio.gov/communications/publications/annual_reports/2025annualreport.pdf) estimates that 674 municipalities levied an income tax during 2024, 248 cities and 426 villages, with rates ranging from 0.1% to 3%. The most common single rate is 1.0%, used by about 4 in 10 of them. The big cities sit near the top: Cleveland and Columbus both levy 2.5%. The department's [municipal rate table](https://dam.assets.ohio.gov/image/upload/v1741618460/tax.ohio.gov/muni-net-profit/municipal.tax.rate-3.7.25.pdf) lists every one. The count is not the problem. The variation is. Every one of those municipalities writes its own ordinance inside the limits of Chapter 718. Rates differ. The credit a city gives its residents for tax paid elsewhere differs. Who administers the tax differs. Two practices ten minutes apart can face different rates, different administrators and different credit rules, and the practice owner who lives in a third city adds a third set. Here is what that means in money, using illustrative numbers. Take a practice with $300,000 of net profit for city tax purposes. At a 1.0% city rate, the net profit tax is $3,000. At 2.5%, it is $7,500. The dentistry is identical. The $4,500 difference comes from the address on the lease. A CFO prices that before choosing a second location, not after the first return arrives. ## Who Pays: The Practice, the Team and the Owner Start with the practice. Under [ORC 718.01](https://codes.ohio.gov/ohio-revised-code/section-718.01), a business that is not an individual pays city tax on its own net profit, and a pass-through entity computes that profit as if it were a C corporation. In plain terms, your S corporation or multi-member LLC is a taxpayer at the city level even though it pays no federal income tax of its own. The city taxes the practice where the practice operates. Your choice of [S corp or LLC](https://reciprocityaccounting.com/blog/dental-practice-s-corp-vs-llc) does not make that go away. One wrinkle matters for partnerships and LLCs taxed as partnerships. The statute says guaranteed payments to partners and members are not deductible when computing city net profit. A payment that lowers your federal partnership income does not lower your city tax base the same way. A single-member LLC that is disregarded for federal purposes is not a separate taxpayer at all. Its profit flows to the owner and is taxed there. Next, the team. Every employer doing business in a taxing city withholds that city's tax from wages earned there, under [ORC 718.03](https://codes.ohio.gov/ohio-revised-code/section-718.03). The rule is where the work happens, not where the employee lives. We cover the payroll side in detail in its own post on Ohio municipal withholding. Then you. This is where the most common Ohio myth lives, so read it carefully. ## Work City vs Residence City The usual story says an owner pays once where the practice operates and again where they live. For an S corporation owner, that story is mostly wrong. ORC 718.01 lists an S corporation shareholder's distributive share of net profit as exempt income, other than any part that represents wages or net earnings from self-employment. The practice already paid city tax on that profit at the entity level, so the shareholder's share is not taxed again. The statute does carry a narrow grandfather clause for a small number of cities whose voters approved taxing it in elections held in 2003 or 2004, so confirm your residence city is not one of them. But the default is clear: your K-1 profit from an S corporation is not a city tax event for you. Your W-2 salary from the practice is a different matter. It is wages. It is taxed by the city where you work, through withholding like anyone else on the team. Your residence city may tax it too. Whether it then gives you a credit for the tax your work city already took is up to that city. [ORC 718.04](https://codes.ohio.gov/ohio-revised-code/section-718.04) says a city "may" grant a credit for all or part of tax paid to another city. It does not have to. Some give a full credit. Some give a partial one. A few give none. That is the real decision point for an Ohio owner, and it connects directly to how you pay yourself. Under an S corporation, the split between salary and distributions is already one of the biggest [owner compensation](https://reciprocityaccounting.com/blog/dental-practice-owner-compensation) choices you make. In Ohio, the salary side carries city tax at your work city's rate, plus whatever your residence city keeps after its credit. The distribution side does not. That does not mean you should pay yourself less than reasonable compensation. It means the city layer belongs in the conversation with whoever prepares your returns, and the numbers for your two specific cities should be in front of you when you have it. Partnership and LLC owners sit in a different spot. The statute excludes a nonresident's share of pass-through profit, but it does not give residents the same exclusion. If your practice is a partnership and you live in a different city from the one where it operates, your residence city may tax your share, subject to its own credit rules. ## The 20-Day Occasional Entrant Rule Ohio does not make an employer chase every city an employee sets foot in. Under [ORC 718.011](https://codes.ohio.gov/ohio-revised-code/section-718.011), an employer is not required to withhold for a city where an employee works on 20 or fewer days in a calendar year, as long as the employer is withholding for that employee's principal place of work. A day only counts toward a city if the employee spent more time working there that day than in any other city. On the 21st day, the obligation turns on. From then on, the employer must withhold and remit to the second city for every later day that year the employee works there. Withholding for the first 20 days is optional, and if the employer does go back and withhold for them, the tax already paid to the principal city for those days becomes refundable to the employee. There is a carve-out for small employers. A practice that had total revenue under $500,000 in the prior year, and the statute counts patient service revenue, withholds only to the city of its fixed location regardless of where employees travel. Most established practices are over that line. A first-year startup may not be, and the rule changes the year after revenue crosses it. For a single-office practice with a stable team, the 20-day rule rarely bites. It bites when you add a second office, share a hygienist across both, or send a doctor to cover another location on a regular schedule. That is a scheduling decision with a tax consequence, and the payroll system has to know which city each day belongs to. ## RITA and CCA: Two Administrators, Different Rules Most Ohio cities do not run their own tax office. They contract it out. The [Regional Income Tax Agency](https://www.ritaohio.com/About), RITA, acts for more than 360 Ohio cities and villages. The [Central Collection Agency](https://ccaohio.gov/member-municipalities), CCA, run by the City of Cleveland, lists 36 member municipalities including Cleveland itself. The Department of Taxation also names the City of St. Marys and the City of Findlay as third-party administrators for other towns. And many of the larger cities administer their own tax: [Columbus](https://www.columbus.gov/Government/City-Auditor/Income-Tax-Division/General-Income-Tax-Information) and [Cincinnati](https://www.cincinnati-oh.gov/finance/income-taxes/) both run their own income tax divisions. The administrator decides your forms, your portal, your registration and your due dates. A practice in a RITA city registers with RITA, files withholding with RITA and files its net profit return with RITA. A practice in Columbus does all of that with Columbus. A two-office practice can easily answer to two administrators with two sets of rules for the same kind of filing. There is one way to consolidate part of it. Under [ORC 718.80](https://codes.ohio.gov/ohio-revised-code/section-718.80), a business can elect to file its municipal net profit tax with the state through the Ohio Business Gateway instead of with each city, and the tax commissioner becomes the sole administrator of that return. The election has to be made by the 15th day of the fourth month of the tax year, so April 15 for a calendar-year practice,. Miss that date and the election waits for the next tax year. Sole proprietors and disregarded entities are not eligible. For a multi-city practice, one net profit return instead of several is worth a look. The election covers the net profit tax. It does not move your employee withholding. ## The Calendar the Practice Runs On Here is the year for a calendar-year S corporation filing with its city, from the statute. | What | When | Rule | | --- | --- | --- | | Estimated net profit tax, 22.5% of the year | April 15 | ORC 718.08, required if the amount payable as estimated tax is $200 or more | | Estimated net profit tax, cumulative 45% | June 15 | Same | | Estimated net profit tax, cumulative 67.5% | September 15 | Same | | Estimated net profit tax, cumulative 90% | December 15 | Same, for a business | | Annual net profit return | April 15 of the next year | ORC 718.05, 15th day of the fourth month after year-end, or the federal due date if later | | Extended net profit return | November 15 | A federal extension carries over; the extension is to file, not to pay | | Withholding payments | Monthly or quarterly | ORC 718.03, set by last year's withholding | | Withholding reconciliation with W-2 detail | Last day of February | ORC 718.03 | The estimate rules carry a safe harbor. Under ORC 718.08, a practice avoids underpayment trouble if its estimates cover at least 90% of the current year's tax, figured by annualizing income, or 100% of the prior year's tax, if a full-year return was filed with that city for the prior year. That makes the prior-year return the easiest anchor for a stable practice, and it makes a big jump in profit the moment to revisit the estimate rather than ride it. Two more rules from the statute are worth knowing. A loss year is not wasted: a business can carry a city net operating loss forward up to five years, and for tax years beginning in 2023 or later the full carried loss is deductible, not the 50% some cities allowed before. And a multi-city practice splits its net profit among cities using an equally weighted average of three factors in [ORC 718.02](https://codes.ohio.gov/ohio-revised-code/section-718.02): property, payroll and gross receipts in each city, with rented property counted at eight times the annual rent, unless an alternative method applies. A 2023 change, in [ORC 718.021](https://codes.ohio.gov/ohio-revised-code/section-718.021), also lets businesses with remote employees or owners elect a modified formula. ## What This Requires of Your Chart of Accounts Here is where the city layer stops being a tax question and becomes a bookkeeping one. Four things have to be true in the books, or year-end turns into reconstruction. **One withholding liability per city, not one bucket.** City tax withheld from your team is not your money. ORC 718.03 says it is held in trust for the city, the employer owes it whether or not it was actually withheld, and the person responsible for remitting it can be personally liable. Each city reconciles on its own, so each needs its own payable account that withholding runs into and remittances clear. If the balance in a city's account is not zero after the payment posts, something was missed. **City net profit tax below the line.** In our [chart of accounts template](https://reciprocityaccounting.com/blog/dental-chart-of-accounts-template), income taxes sit below net operating income, and the city's tax on your profit belongs there with them. It is a tax on what the practice earned, not a cost of producing dentistry. Put it in overhead and your [overhead percentage](https://reciprocityaccounting.com/blog/dental-practice-overhead-percentage) stops being comparable to anyone else's, Ohio or not. **Estimates booked as prepayments.** Four estimated payments a year will make the monthly P&L lumpy if each one hits expense when paid. Booked as a prepayment against the year's liability, with the expense recognized each month, the monthly numbers stay readable and the year-end true-up is a small entry instead of a surprise. **Payroll tagged by work location.** The payroll register has to know which city each employee worked in, by day when people move between offices. That one field drives the withholding, the 20-day count and the payroll factor in the apportionment formula. A practice that cannot produce wages by city cannot file a multi-city return correctly. None of this needs a special Ohio chart. It needs a [standardized chart of accounts](https://reciprocityaccounting.com/blog/dental-practice-standardized-chart-of-accounts) with room for a city-level line where Ohio requires one, and books closed monthly so each city's balance is checked every month instead of once a year. ## The Compliance Cost Nobody Prices In Count the filings for one office in one city. A practice large enough to withhold monthly files 12 withholding returns and one annual reconciliation. It makes four estimated net profit payments and files one annual net profit return. That is 18 filings a year for a single city, before the state return, before federal payroll filings, and before the [school district income tax](https://tax.ohio.gov/individual/school-district-income-tax) the Department of Taxation administers separately for employees who live in a taxing district. Add a second office in a city with a different administrator and you roughly double the city layer: a second registration, a second withholding calendar, apportionment on the net profit return and a payroll register that has to split wages by location. Each of those is small. Together they are a standing monthly workload that nobody puts in the pro forma when the second lease is signed. That is the decision this post is really about. The city tax itself is usually a few thousand a year. The cost of handling it badly, in penalties, amended returns and hours spent rebuilding a year of withholding by city, is often larger than the tax. Ohio rewards the practice whose books are [closed by the 10th](https://reciprocityaccounting.com/blog/dental-books-monthly-close-deadline) with city balances reconciled every month, and it punishes the one that finds out in April. If you want the shorter version of the basics, our earlier post on [how municipal taxes affect your Ohio dental practice](https://reciprocityaccounting.com/blog/ohio-municipal-tax-dental-practice) covers the essentials in a quicker read. *P.S.* [*Reciprocity Accounting*](https://reciprocityaccounting.com) *closes your books by the 10th with a separate, reconciled balance for every city you withhold for, so Ohio's filings come due on numbers that are already right.* [*See how we can help your practice.*](https://reciprocityaccounting.com/contact) ## Frequently Asked Questions ### Does my S corporation owe Ohio municipal tax, and do I owe it again on my K-1? The S corporation pays city net profit tax at the entity level where it operates. Under ORC 718.01, your distributive share as a shareholder is exempt income, other than any part that represents wages, so your K-1 profit is generally not taxed again by your city. A small number of cities whose voters approved taxing it in 2003 or 2004 may still do so. Your W-2 salary is wages and is taxed like anyone else's. ### Does my residence city have to give me a credit for tax paid where I work? No. ORC 718.04 lets each city decide whether, and how much, to credit its residents for tax paid to another city. Some give a full credit, some a partial one, some none. Check your residence city's ordinance or its administrator's rate table before assuming the tax is not doubled. ### How many Ohio cities have an income tax? The Ohio Department of Taxation counted 674 municipalities levying an income tax during 2024, with rates from 0.1% to 3%. About 4 in 10 use a 1.0% rate. Cleveland and Columbus are at 2.5%. ### When are Ohio municipal estimated payments due for a dental practice? Under ORC 718.08, a calendar-year business whose estimated city tax payable is at least $200 pays cumulative estimates of 22.5% by April 15, 45% by June 15, 67.5% by September 15 and 90% by December 15. Covering 100% of last year's tax, if you filed a full-year return with that city, or 90% of this year's avoids underpayment problems. ### Can I file one municipal net profit return instead of one per city? Yes, if you elect under ORC 718.80 to file through the Ohio Business Gateway. The election must be made by the 15th day of the fourth month of your tax year, April 15 for a calendar year, and a missed deadline means waiting for the next tax year. Sole proprietors and disregarded entities cannot elect. Employee withholding still goes to each city or its administrator. ### Where does municipal net profit tax go on my P&L? Below the line, with income taxes, under net operating income. It is a tax on profit, not a cost of producing dentistry, so keeping it out of overhead keeps your overhead percentage comparable. **Related reading:** - [How to Structure Your Dental Practice in Ohio: Entity, Tax, and Compliance Basics](https://reciprocityaccounting.com/blog/ohio-dental-practice-entity-structure) - [Owner Pay in a Dental Practice: How to Account for It Correctly](https://reciprocityaccounting.com/blog/dental-practice-owner-compensation-bookkeeping) - [How to Prepare Your Dental Practice for a Clean Year-End Close](https://reciprocityaccounting.com/blog/dental-practice-year-end-bookkeeping) ## Share this post [mailto:https%3A%2F%2Freciprocityaccounting.com%2Fblog%2Fohio-municipal-income-tax-dental-guide](mailto:https%3A%2F%2Freciprocityaccounting.com%2Fblog%2Fohio-municipal-income-tax-dental-guide) ## Keep reading ### [![Reciprocity Accounting card: A Clean Year-End Close, a How To post.](https://reciprocityaccounting.com/hs-fs/hubfs/blog-images/post_64.png?width=1200&height=630&name=post_64.png) How To Clean Year-End Close for Dental Practices: Checklist](https://reciprocityaccounting.com/blog/dental-practice-year-end-bookkeeping) ### [![Reciprocity Accounting card: Books Ready for Tax Season, a How To post.](https://reciprocityaccounting.com/hs-fs/hubfs/blog-images/post_63.png?width=1200&height=630&name=post_63.png) How To Preparing Your Dental Practice Books for Tax Season](https://reciprocityaccounting.com/blog/dental-practice-tax-season-bookkeeping) | ![Reciprocity Accounting](https://reciprocityaccounting.com/hubfs/logo_horizontal_dark_transparent.png) Accounting built for dental practices.
