Public investments, such as building transportation or sewer facilities, can increase adjacent land values, generating an unearned profit for private landowners. The unearned value (increases in land value which otherwise profit private landowners cost-free) may be "captured" directly by converting them into public revenue (see georgism). Thus, value capture internalizes the positive externalities of public investments, allowing public agencies to tax the direct beneficiaries of their investments.
Urban planners and finance officials are often interested in value capture mechanisms, for at least two reasons: 1) because they offer a targeted method to finance infrastructure benefiting specific land, and 2) because some such investments can generate private investment in the area, which will more widely benefit the city (e.g., by providing employment opportunities, shopping and other amenities, and a more robust and diverse tax base.) It can be politically useful to capture for the city treasury a share of the positive externalities of city-financed investment. This can help address public concern about the fact or perception of unfair windfalls when specific owners’ land values increase after urban infrastructure investment is paid from general city revenues.
Although it is not always talked about as such, the most common value capture mechanism is the general real property tax, with no special features other than regular assessment of market value; this is because the common real estate tax includes the less known land value tax. The value of any given land is determined by its proximity to various amenities (both public and private). Thus, for example, when a new subway station or highway interchange is installed, land near the new facility becomes more valuable. Investment in capital improvements to land can synergistically generate capital investment in other nearby locations, which further increases land value. Thus, even if the rate of taxation does not change, the tax revenue generated from properties which benefit goes up by way of higher land values and increased development. The effectiveness of value capture depends, of course, on a smoothly functioning ad valorem property or land value tax system, with regularly updated assessments.
Value capture strategies can be applied to developers or landowners, and they can be applied before or after a public improvement is built. In the case of new public transit facilities, the property value premium nearby can be as high as 167%. Types of value capture include the following:
- Land value tax (LVT)
- Tax-increment financing (TIF)
- Special assessment districts or improvement districts
- Infrastructure impact fees (such as traffic or utility fees)
- Joint development
- Air rights
- Exactions, public easements, or other nonpossessory interests
