2022 update:

As was the case last year, you can save a few more $$ if you don't need to file a state return and are willing to upload all your data to the cloud. Personally I pay extra for the download as I prefer to keep my tax software and data on my laptop. Of course the return still gets uploaded to the IRS.

Note that many Chase cards (e.g. CSP) have an opt-in rebate offer for $10 cash back on Intuit purchases. I am hoping this applies to the e-file fees and not just the software.

TurboTax Deluxe (no state):
$29 with Fidelity customer discount (see link) - online only (no download)
$34 with Chase customer discount (see link) - online only (no download)

As previously noted, if you have a very simple return there are plenty of free federal programs (including at the IRS website). But if you have any kind of itemized deductions or non-wage income fergetaboutit.[/QUOTE]
