The Michigan Income Calculator helps you estimate your take-home pay after accounting for Michigan state income tax, federal FICA taxes (Social Security and Medicare), and potential local city income taxes. Understanding these deductions is crucial for budgeting and financial planning.
Michigan State Income Tax
Michigan currently has a flat state income tax rate. For 2024, this rate is 4.25%. This means that a fixed percentage of your taxable income is paid to the state. Before applying the tax rate, you can deduct a personal exemption for yourself and any dependents. For 2024, the personal exemption amount is $5,200 per exemption.
Federal FICA Taxes
FICA stands for Federal Insurance Contributions Act and includes Social Security and Medicare taxes. These are federal taxes, but they are a significant deduction from most paychecks, so they are included in this calculator for a more realistic net income estimate.
Social Security: For 2024, the Social Security tax rate is 6.2% on earnings up to a certain annual limit ($168,600). Income above this limit is not subject to Social Security tax.
Medicare: The Medicare tax rate is 1.45% on all earned income, with no income limit.
Michigan City Income Taxes
Several cities in Michigan levy their own income taxes in addition to state and federal taxes. These rates vary by city and can apply to residents and/or non-residents who work within the city limits. Common cities with income tax include Detroit, Grand Rapids, Lansing, and others. If you live or work in one of these cities, you'll need to factor in this additional deduction.
How the Calculator Works
Simply enter your gross annual income and the number of personal exemptions you claim. If you are subject to a city income tax, check the box and enter the applicable rate. The calculator will then estimate:
Your Michigan State Income Tax
Your Federal FICA Taxes (Social Security and Medicare)
Any applicable City Income Tax
Your total annual deductions
Your estimated Net Annual and Net Monthly Income
Example Calculation (2024 Rates)
Let's say an individual earns $70,000 annually, claims 1 personal exemption, and is subject to a 1.5% city income tax.
Gross Annual Income: $70,000.00
Number of Exemptions: 1
Michigan Personal Exemption: 1 × $5,200 = $5,200.00
Net Annual Income: $70,000.00 – $9,159.00 = $60,841.00
Net Monthly Income: $60,841.00 / 12 = $5,070.08
