HSA

[Al36]

How do you separate employer contributions from employee contributions listed under W on W-2 when they are combined on the w-2.

[JohnW152]

You don't separate out the contributions by their sources. 

You must report the HSA contributions as they appear on your Form W-2. 

Please see the TurboTax Help article Where do I enter my HSA contribution? for more information.

[Opus 17]

Under this particular section of the tax code, you agree to a voluntary salary reduction, and you employer agrees to contribute that money to the HSA for you, along with any employer matching funds.  Therefore, all payroll contributions are technically made by the employer.  

Later in the program, you only report additional out-of-pocket contributions you made directly to the bank and not via payroll.
