The Chargers reportedly want San Diego voters to raise taxes on hotel stays to pay for a $1.8 billion combination stadium and convention center next to Petco Park in downtown San Diego.
The San Diego Union-Tribune quoted sources Tuesday as saying the team will propose an increase in the tax paid by visitors from 12.5 percent to 16.5 percent to finance the project.
The plan would be presented to voters during the presidential general election in November.
The city has proposed renovating Qualcomm Stadium in Mission Valley with financing from a bond issue, but the Chargers have been adamant that they prefer a downtown location.
Although both plans would require voter approval, neither would raise taxes.
