Story highlights At issue for Republicans: State and local tax deductions, known as SALT

Cutting SALT would raise more than a trillion dollars to help pay for the GOP plan

Republicans from high-tax states like New York, New Jersey and California had expressed serious concerns about killing the state and local tax deduction, a provision known as SALT, which lets taxpayers deduct levies like property taxes, state income taxes and local sales taxes.

Nixing SALT would let Republicans raise more than $1 trillion dollars to help pay for their tax plan, congressional negotiators say.

After weeks of talks with Republicans who rejected the idea, House Ways and Means Chairman Kevin Brady announced a concession over the weekend , saying they'd preserve the deduction for property taxes, which affects more middle income tax payers than the state income tax deduction.
