Can I Deduct 2018 HSA contributions on my 2017 tax return?

Yes, you can deduct HSA contributions you made directly for 2017.  Keep in mind, TurboTax automatically pulls the contributions reported on your W2 (Box 12 Code W ) so do not duplicate those.  You will only need to enter any HSA contributions that you made directly that were not withheld from your wages.

Please follow these instructions to enter the HSA contributions you made directly:

• Sign into your account and click "Take Me To My Return"
• Click "Federal" from the left side-bar
• Click the "Deductions & Credits" Tab near the top
• Scroll down until you reach "Medical" and choose "Show More"
• Click "Start" next to HSA MSA Contributions
• From here TurboTax will walk you through some questions and will give you the opportunity to input the amount of your HSA contributions

Please comment below if you have additional questions regarding this issue so that I can assist you further.

So far this year in 2018, I have contributed $490 in my HSA that was directly deposited from my paycheck into my HSA. So I cannot enter this amount to my 2017 tax return?

No, you cannot enter that amount on your 2017 Tax Return.

If I open an HSA account for monies given to me for family coverage that runs October 2017 thru September 2018, can I deduct if from 2017 taxes and use the family coverage maximum?  My kids were still covered under their father's insurance as well thru the end of 2017.

Please post your question separately so that an agent can specifically address it.
