How Property Tax Works

Grant County, Indiana operates on a property tax system that serves as the primary funding mechanism for essential local services including public schools, law enforcement, fire protection, road maintenance, and county government operations. Property taxes in Grant County are collected annually and distributed among various taxing units including the county, townships, municipalities, school districts, and special service districts.

The effective property tax rate in Grant County typically ranges from approximately 1.0% to 1.4% of assessed value, though actual rates vary significantly by location within the county due to different combinations of special taxing districts. Each property's total tax rate is determined by the sum of all applicable taxing unit rates for that specific location. Properties are assessed at 100% of their true tax value, with assessment increases for homestead properties capped through Indiana's homestead credit system.

Supplemental Tax Bills

Supplemental property taxes in Grant County are additional assessments that occur when there are changes to a property's assessed value outside the regular annual assessment cycle. The most common triggers include change of ownership, completion of new construction, additions or major improvements to existing structures, or discovery of previously unassessed property improvements.

When a supplemental assessment is issued, the additional tax is calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value. The supplemental tax is prorated based on the number of months remaining in the tax year from the effective date of the change. For example, if a $50,000 addition is completed in July and increases the assessed value accordingly, the supplemental tax would be calculated on that $50,000 increase for the remaining 6 months of the tax year at half the annual rate.

Escrow & Property Taxes

Most mortgage lenders in Grant County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders may require escrow regardless of down payment amount. The lender collects monthly payments equal to 1/12th of the estimated annual property tax bill and holds these funds in a separate escrow account. Property taxes in Grant County are paid in two installments annually, and the lender will make these payments directly to the county treasurer on behalf of the homeowner.

Lenders are required to provide annual escrow statements showing all deposits and payments, and may adjust monthly payments if the account balance is projected to be insufficient or excessive. Homeowners should verify that their lender is making payments on time, as the property owner remains ultimately responsible for tax payments even when using escrow. If you pay your own taxes without escrow, remember that the first installment is due by December 10th and the second installment by May 10th of the following year, with payments considered timely if made by month-end when due dates fall on weekends or holidays.

Frequently Asked Questions

Q: When are property taxes due in Grant County for the current fiscal year? A: For tax year 2024 (payable in 2025), the first installment is due December 10, 2024, and the second installment is due May 10, 2025. If the due date falls on a weekend or holiday, payment is considered timely if made by the end of that month.

Q: What is the homestead credit and how do I apply? A: The homestead credit caps the annual increase in assessed value for your primary residence, but requires filing Form 322 with the county assessor. This credit limits assessment growth rather than reducing market value, and must be applied for - it is not automatic.

Q: Are there other tax credits available in Grant County? A: Yes, qualifying veterans may be eligible for veterans' disability tax credits, and senior citizens may qualify for additional credits based on income. All credits require separate applications with specific deadlines and documentation requirements.

Q: When are properties reassessed and how can I appeal? A: Assessment notices (Form 11s) are typically mailed April 28th annually. Property owners have until June 15th to file appeals with the County Assessor's office if they disagree with their assessed value.

Q: What are the penalties for late property tax payments? A: Late payments incur a 10% penalty, and if taxes remain unpaid, the property may eventually be subject to tax sale proceedings. Interest may also accrue on unpaid balances.

Q: Can I pay my property taxes online? A: Yes, Grant County offers online payment options through their official website. You can also search past tax bills and assessed values through their online database system.

Q: Why do tax rates vary within Grant County? A: Different areas are served by different combinations of school districts, fire departments, libraries, and special service districts. Your total tax rate is the sum of all applicable taxing units for your specific location.

Q: What exemptions are available for organizations? A: Qualifying religious, educational, and charitable organizations may be eligible for institutional exemptions that remove property from the tax rolls entirely. These require detailed applications and annual filings to maintain exempt status.
