Tapered match is a form of Federal-aid matching flexibility that allows a project's Federal share to vary from year to year as long as the final contribution of Federal funds does not exceed the project's maximum authorized share. This tapered match, or delayed local match, as it is commonly called for transit projects, allows states to vary the required matching ratio over the life of a project. For example, the Federal share could start out at 100 percent and taper off to zero as the project nears completion.
With tapering, a state can advance a project before fully securing bond and capital market financing. Tapered match may also be useful when the project sponsor lacks the funds needed to match a Federal-aid project at the start, but will accumulate the match over the life of the project. For example, this technique may facilitate a project when a new local tax has recently been enacted. Using tapered match, the project can move forward immediately with 100 percent Federal funds, allowing time for the new tax revenues to accumulate. The use of tapered match also may help a state overcome near-term gaps in state matching funds.
Historically, tapered match underwent several years of experimentation through TE-045 and was formally instituted when TEA-21 amended Sections 121 and 133 of Title 23, no longer requiring that the Federal share of project costs be applied to each progress payment. Instead, the Federal share is applied to the total project costs.
An example is provided below illustrating a tapered match project with total project costs of $200 million. In this example the required non-Federal match is equal to 20 percent of total project costs, or $40 million. The project construction timeframe is four years. During the first two years of construction, the Federal contribution is equal to 100 percent of project costs. The state begins to provide the non-Federal share starting in year 3 and by the end of year 4 has provided its entire $40 million share of funding for this project, i.e. the entire 20 percent of total contributions to the project.

States may request use of a tapered match approach for most projects eligible for Federal-aid assistance under Title 23, as approved by an FHWA Division Administrator. Tapered match cannot be used on advance construction projects, STP projects for which the non-Federal match is being provided on a program-wide basis, or projects that are financed with GARVEE bonds, as these activities are considered to be inconsistent with the intent of tapered match. Approval is granted when the use of tapered match results in one or more of the following:
Use of tapered match, when compared to the use of traditional match procedures, would result in an earlier project completion
Project costs would be reduced by using a tapered match
Use of tapered match would provide for additional non-Federal funds to be leveraged for the project
For purposes of application of costs incurred to the non-Federal share requirement of the project, a fourth condition is added:
When costs for services are donated by a local public agency acting as a third party, incurred by a local public agency acting as a subgrantee, or in limited circumstances, a state agency acting as a grantee. Advance construction procedures (23 U.S.C. 115) may be used in conjunction with this fourth tapered match condition only. Authorization for this option may be granted by the FHWA Division Administrator, case-by-case, dependent upon assurance of the existence and effectiveness of necessary procedures and related internal controls.
The process for using a tapered match is as follows:
