How Property Tax Works

Saginaw County, Michigan operates under a property tax system that funds essential local services including schools, county government, municipalities, and various special districts. Property taxes are the primary source of revenue for these local governmental units. The county follows Michigan's assessment and taxation procedures, with properties assessed at approximately 50% of their true cash value (market value) to determine the taxable value.

Property tax rates in Saginaw County vary significantly by location within the county due to different combinations of taxing jurisdictions and special districts. For the 2025 tax year, combined millage rates range from approximately 10.8485 mills for summer collections to 20.2204 mills for winter collections per $1,000 of taxable valuation. Your actual tax rate depends on which city, township, school district, and special assessment districts your property is located within. The City of Saginaw, for example, has a property tax rate of 0.529649 for fiscal year 2025-2026, representing an increase of 0.035902 from the previous year.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.

Supplemental Tax Bills

Supplemental taxes in Saginaw County are additional property tax assessments that occur when there are changes to a property's assessed value during the tax year. Common triggers include new construction, completion of building permits, property improvements, or corrections to assessments discovered after the initial tax roll was prepared.

When supplemental taxes are levied, they are calculated by applying the current millage rates to the difference between the old and new assessed values. For example, if new construction increases your property's taxable value by $50,000 mid-year, and your total millage rate is 31.069 mills (combining summer and winter rates), your supplemental tax would be approximately $1,553 ($50,000 ÷ 1,000 × 31.069). Supplemental tax bills are typically issued shortly after the assessment change is processed and have separate due dates from regular property tax collections.

Escrow & Property Taxes

Most mortgage lenders in Saginaw County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly escrow payments along with your mortgage payment and pays your property taxes directly to the county when due. Escrow payments are calculated by estimating your annual property tax bill and dividing by 12 months, often with a buffer amount to ensure adequate funds.

Saginaw County issues tax bills in summer (typically July) and winter (typically December), with due dates usually falling in August/September for summer taxes and February/March for winter taxes. Your lender will receive these bills and make payments from your escrow account. You should receive an annual escrow analysis statement showing how your account funds were used and any adjustments needed for the coming year. If your property taxes increase due to reassessment or millage changes, your monthly escrow payment may be adjusted accordingly.

Frequently Asked Questions

Q: When are property taxes due in Saginaw County for the current fiscal year? A: Summer property taxes are typically due in August/September, while winter taxes are due in February/March. Payment options include mailing to Saginaw County Treasurer, 111 S. Michigan Avenue, Saginaw, MI 48602, or paying online 24/7 using Visa or other accepted payment methods.

Q: What tax credits are available and do I need to apply? A: The primary credit is the Homestead Property Tax Credit, which caps assessment increases for owner-occupied homes. This credit REQUIRES annual application and is not automatic. Contact the Saginaw County Assessor's office to determine available credits and application requirements specific to your situation.

Q: How does the Homestead credit work? A: The Homestead credit limits how much your property's taxable value can increase each year (typically to inflation rate or 5%, whichever is less), rather than reducing your property's market value. You must file annually to maintain this benefit - it does not happen automatically.

Q: How often are properties reassessed? A: Michigan law requires properties to be assessed annually, but major reappraisals typically occur every few years. You'll receive assessment notices in the spring with appeal deadlines usually in March.

Q: What happens if I pay my property taxes late? A: Late payments are subject to penalties and interest. Delinquent real property taxes must be paid directly to the Saginaw County Treasurer's Office and cannot be paid through the regular online system.

Q: Can I pay my property taxes online? A: Yes, online payments are available 24 hours a day, 7 days a week through the county's system. Accepted payment methods include Visa and other major payment options. However, online payments can ONLY be made on current tax collection periods.

Q: What are special district taxes? A: These are additional millages for services like fire protection, libraries, parks, or drainage districts. The special districts serving your property depend on your specific location within Saginaw County and appear as separate line items on your tax bill.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed with the local Board of Review, typically in March. Contact your local assessor's office for specific deadlines and required documentation to support your appeal.
