What Is Tax Increment Financing?
Tax increment financing (TIF) is an economic development tool used by municipalities to encourage private investment in designated areas. When a TIF district is created, the property tax base is frozen at its current level. As new development increases property values and generates higher tax revenue, the “increment” — the difference between the new, higher tax revenue and the frozen base — is captured and used to fund public improvements within the district.

At Howard East, we advise developers, businesses, and municipalities on TIF agreements, redevelopment incentives, and the legal structures that make public-private partnerships work.
How TIF Districts Are Created
Municipalities establish TIF districts through a formal process that typically includes designating the geographic boundaries, documenting conditions that qualify the area for TIF (blight, conservation need, or industrial park designation), preparing a redevelopment plan, and holding public hearings. The governing body must adopt the plan by ordinance, and the TIF district has a defined lifespan — typically 23 years in Illinois.
The redevelopment plan identifies the expected public improvements, projected costs, and the anticipated private investment that the TIF is designed to attract.
Eligible TIF Expenditures
TIF funds can be used for a range of public purposes, including infrastructure improvements (streets, utilities, sidewalks), environmental remediation, land acquisition and demolition, building rehabilitation, public facilities, and certain developer incentives. The specific eligible expenditures vary by state statute.
Benefits for Businesses and Developers
TIF can significantly improve the economics of development projects in areas that might otherwise be financially unviable. Developers may receive direct TIF assistance through reimbursement of eligible costs, reduced infrastructure expenses, or land write-downs. Businesses locating in TIF districts benefit from improved infrastructure, reduced blight, and the economic activity that concentrated development brings.
However, TIF agreements are complex legal documents with specific performance requirements, reporting obligations, and clawback provisions if the developer fails to meet its commitments. Having experienced legal counsel review and negotiate these agreements is essential.
Risks and Criticisms
TIF is not without controversy. Critics argue that TIF diverts tax revenue from schools and other taxing bodies, may subsidize development that would have occurred anyway, and can extend the timeline for surrounding areas to benefit from increased property values. Some municipalities have experienced problems with overly generous TIF agreements that fail to deliver promised economic benefits.
Our attorneys help clients evaluate both the opportunities and risks of TIF participation, ensuring that the legal protections in the agreement match the economic expectations of the transaction.
TIF in Illinois
Illinois has one of the most active TIF programs in the country, with hundreds of active TIF districts statewide. The Illinois Tax Increment Allocation Redevelopment Act (65 ILCS 5/11-74.4) governs TIF creation and administration. Chicago alone has more than 130 active TIF districts generating billions in increment revenue.

How Tax Increment Financing Benefits Developers
Tax increment financing benefits developers by reducing upfront infrastructure costs and making otherwise uneconomic projects financially viable. TIF districts often fund street improvements, utility upgrades, environmental remediation, and public space improvements that would otherwise fall on the developer’s budget. This public-private partnership model has revitalized commercial corridors and industrial areas across Illinois and nationwide.
Tax Increment Financing Risks and Limitations
Tax increment financing carries risks for both municipalities and developers. If projected development does not materialize, the tax increment may be insufficient to cover TIF obligations. Other taxing bodies — schools, parks, and libraries — lose revenue during the TIF period. Developers must navigate complex approval processes and compliance requirements to participate in TIF programs successfully.
Frequently Asked Questions
What is tax increment financing?
Tax increment financing is a public financing method that uses the projected increase in property tax revenue from new development to fund infrastructure improvements in designated areas. The increased tax revenue — the “increment” — is captured and reinvested in the TIF district rather than going to the general tax fund.
How long do TIF districts last?
TIF districts typically last 23 years in Illinois, though some states allow different durations. After the TIF period expires, the full assessed property value returns to the regular tax rolls, benefiting all taxing bodies including schools and municipalities.
Who benefits from tax increment financing?
Tax increment financing benefits developers through reduced infrastructure costs, municipalities through increased economic activity and property values, and communities through improved neighborhoods, new jobs, and enhanced public infrastructure. When structured properly, TIF creates a positive cycle of investment and growth.
