What business taxes do Michigan small businesses pay?
Michigan small businesses typically pay a combination of federal and state taxes. The specific obligations depend on your business structure, whether you have employees, and whether you sell taxable products or services.
At the federal level, you pay income tax on business profits. Sole proprietors and single-member LLCs report income on Schedule C of their personal return. Partnerships and S-Corps pass income through to owners who pay tax on their individual returns. C-Corps pay corporate income tax separately. Most small business owners also pay self-employment tax of 15.3% on net earnings to cover Social Security and Medicare.
Michigan has a flat 4.25% income tax rate. For pass-through businesses like sole proprietorships and LLCs, your share of business income gets added to your Michigan individual return. C-Corps pay the Corporate Income Tax at 6% on Michigan-sourced income. Michigan doesn’t have a general franchise tax or minimum tax for small businesses, which makes it relatively straightforward compared to states like California or Texas.
If you sell tangible goods or certain services, you need to collect Michigan sales tax at 6%. You register with the Michigan Department of Treasury, collect tax from customers, and remit it monthly, quarterly, or annually depending on your volume. Use tax applies when you buy items for business use without paying sales tax, like equipment purchased from out-of-state vendors.
When you have employees, the tax obligations increase significantly. You withhold federal income tax and FICA from wages, pay the employer portion of FICA at 7.65%, and pay federal unemployment tax. Michigan requires state income tax withholding at 4.25% and state unemployment insurance contributions. New employers typically start around 2.7% for unemployment, though rates vary based on your claims history over time.
Quarterly estimated tax payments are required if you expect to owe $1,000 or more for the year. This applies to both federal and Michigan taxes. Missing these payments triggers penalties and interest even if you pay everything by April 15. Many business owners get caught off guard by this because they’re used to employer withholding handling taxes automatically.
Business personal property tax is another Michigan consideration. If you own equipment, furniture, computers, or other business assets, you may need to file an annual statement with your local assessor. There’s an exemption for businesses with less than $80,000 in true cash value of personal property, which covers many small operations. Working with Macomb County bookkeepers who understand these local requirements helps you stay compliant without overpaying.
The key to managing all these obligations is keeping accurate books throughout the year. When your income and expenses are tracked properly, calculating estimated payments becomes straightforward. Full-service bookkeeping gives you the monthly financial clarity to plan for tax payments instead of scrambling at deadline time. Waiting until year end to sort through everything means you’ve already missed quarterly payments and accumulated penalties you could have avoided.
