UDS Free e-file offer

This promotional information is provided by UDS

This is a free-for-all system. It employs a combination interview/forms approach, Federal forms, California Resident or Non-Resident/Part-Year (540, 540 2EZ, or 540NR) forms are displayed and can be printed (for record keeping only, not intended for filing). The software is downloaded and the taxpayer can prepare their returns with no information transfer to any outside entity. Taxpayers can create (and e-file) multiple tax returns and can create "what-if" scenarios. Email, Online Chat and, perhaps more importantly, Phone Support is available. Upon taxpayer request, Federal and California transmissions of encrypted returns are uploaded to the UDS server and e-filed; taxpayers automatically check transmission status. There are no charges and no advertisements of any kind.

UDS software can be used first to prepare a taxpayer's Federal return and then secondly to prepare the taxpayer's CA return. In this case, Federal return data flows directly (automatically) into the CA tax return. UDS would then, upon taxpayer request, e-file both Federal and CA tax returns.

Alternatively, if the taxpayer has already filed their Federal return from other software, then the taxpayer would have to enter all the relevant taxpayer Federal data into their CA return. UDS would then, upon taxpayer request, e-file their CA tax return.



Free for all returns. There are no charges.
(A donation button exists)



Taxpayers can migrate a previous year’s UDS tax return to the current tax year. The migration would populate a taxpayer's current-year tax return with a taxpayer's previous year’s UDS tax return which is automatically updated to reflect current tax-year tax-code changes. Alternatively, taxpayers can just create a new tax return with UDS free preparation and e-filing service.
