TIPS on moving Tax Preparer to a new computer or upgrading an old one.

Moving to a new computer? If you bought a new computer and want to copy your prior-year data to that computer for translation, see the last few pages of Chapter 14 of the new User's Guide (pages 14-13 through 14-18). It provides useful information and tips on moving Tax Preparer data from one computer to another, backed by examples for four common scenarios.

NEW: Upgrading old computer to Windows 10? If you upgrade an existing computer to Windows 10, you may encounter printing or start-up problems:

•   Printing: You may have to update the driver for your printer if graphic forms in Tax Preparer do not print properly. While the Windows 10 upgrade automatically installs the required new drivers for most popular printers of recent vintage, it does not update drivers for older or less popular printers, many of which did not yet have Windows 10 drivers available when Windows 10 was first released. You may therefore have to install a new driver from the website for the manufacturer of the printer, if available.
•   Start-up (32-bit only): Tax Preparer may not start because of a change in settings that Microsoft's upgrade to Windows 10 imposes automatically for 32-bit versions of Windows 10. To change the settings back to the ones required by Tax Preparer, see Customer Service Memo CSTP1503. (No such problem exists for 64-bit versions of Windows 10, which are generally installed when you upgrade a 64-bit computer to Windows 10.)

Additional help. Some people have had perplexing problems this year for which there were not immediate solutions. These include failure of the installation programs, failure of Tax Preparer to start, inability to access tax data, and inability for e-file transmission software to find e-file output to transmit. All of the problems are caused by either aggressive anti-virus software or non-standard computer setups. However, convenient solutions for all problems are available and are described in two memos on our Bulletins page:

•   CSTP1501: How to ensure proper installation and updating of Tax Preparer.
•   CSTP1502: How to avert inability to run Tax Preparer's start-up .vbs file.

Prior releases. For details on prior-year changes throughout the tax season, see Changes in Recent Releases for the respective software:

•   Changes for prior-year 1040 (individuals) software
•   Changes for prior-year 1065 (partnerships) software
•   Changes for prior-year 540 (California) software

What are the changes?

Because of the convenience of the web, we issue new releases frequently, even when most of the changes are relatively insignificant. Changes are highlighted in the bottom half of the respective download pages. However, if you want more detail about the most significant changes, there are two other places to look:

•   E-FILE ALERTS. Changes that are of consequence ONLY to e-file returns are documented here. The changes typically avert specific Reject Codes for the e-file return, so if your return is rejected, check this list first to see if you need to update your software and take particular steps to repair your data.
•   BULLETINS. Changes that are significant for both paper and e-file returns are documented here. Technical Change Notices are issued for each significant change, including the steps you may have to take to repair a return prepared with an earlier release.

Changes that are not documented on either of these pages are less serious in nature, including rewording on some on-screen lines to make entries more understandable, correction of spelling errors, correction of line number references on printouts, and technical changes that have no affect on calculations.

IMPORTANT TIP: After you translate a prior-year return to the current-year format, be sure to VIEW ALL TRANSLATED WORKSHEETS to ensure that the worksheets are recalculated under their new format, and to verify that all entries are proper for the current return. This step is especially necessary this year because of major changes in several worksheets.
