Navigating payroll taxes can be complex, especially when dealing with state-specific regulations.
This calculator provides an estimate of the primary payroll taxes deducted from an employee's
gross pay in Ohio. It is crucial to understand that this tool offers an approximation and
does not encompass all potential deductions or specific circumstances. For precise figures,
consult with a payroll professional or refer to official Ohio Department of Taxation
guidelines.
Key Ohio Payroll Tax Components:
Ohio Income Tax: Ohio has a graduated state income tax system. This means
the tax rate increases as your income rises. The rates are applied in tax brackets.
The calculation for this calculator uses the current Ohio income tax rates for
taxable wages. It's important to note that local income taxes may also apply
depending on your work and residence locations within Ohio.
Federal Income Tax: While this calculator focuses on Ohio payroll taxes,
employees in Ohio are also subject to federal income tax. The federal income tax
system is separate and determined by federal tax laws, including various
withholding allowances and tax brackets.
Social Security and Medicare (FICA): Both Ohio and federal employees
contribute to Social Security and Medicare taxes. These are federal taxes, not state-specific,
but are a significant part of any employee's payroll deduction.
Social Security: Currently at 6.2% on wages up to an annual limit ($168,600 for 2024).
Medicare: Currently at 1.45% on all wages, with no income limit. An additional Medicare tax of 0.9% applies to individuals earning over $200,000 (or $250,000 for married filing jointly).
Unemployment Taxes: Both federal and state unemployment taxes are typically
paid by employers, not deducted from employee wages. However, understanding these is part of the overall payroll picture.
How the Ohio Payroll Tax Calculator Works (Simplified):
This calculator estimates your Ohio Income Tax liability based on your provided annual salary
and pay frequency. It then adds the standard federal FICA taxes (Social Security and Medicare).
It assumes a standard filing status and does not account for specific deductions, credits,
or other less common tax situations.

// 3.5% on income between $15,001 and $25,000
