Moving older versions of TaxCalc to a new PC (Individual customers)

Article ID: 2237
Last updated: 29 Mar, 2023

On occasion you may find that you need to move older versions of TaxCalc (pre-2013) to a new computer.

If you purchased the older versions, you can still download and run these versions.

  1. Firstly, download and install the required program to the new computer from our website.
  2. On the new computer, go to and log in to your account using your email address and password.
  3. From the My Products page, click on the link near the bottom that says Download Previous years products and download the version of TaxCalc that you need to run.
  4. Download, install and then license TaxCalc by following the onscreen instructions to license the software by entering a licence code. You cannot licence 2012 or earlier years unless you enter a code. Internet activation has been disabled.

Once TaxCalc is running on the new computer you need to transfer the tax return data files for the relevant year from the old machine. Each year the return files will be shown with the extensions as listed below. The ‘tax year’ is indicated by the last one or two digits of the filename:

Return Type Previous Years 2010-11 2011-12 2013 onwards
SA100 Individual .s06 .s07 .s08 .s09 .tcs11 .tcs12 .tcs13, .tcs14, .tcs15, .tcs16, .tcs17, .tcs18, .tcs19, .tcs20, tcs21, tcs22, tcs23
SA800 Partnership .p06 .p07 .p08 .p09 .tcp11 .tcp12 .tcp13, .tcp14, .tcp15, .tcp16, .tcp17, .tcp18, .tcp19, .tcp20, tcp21, tcp22, tcp23
SA900 Trust .t06 .t07 .t08 .t09 .tct11 .tct12 .tct13, .tct14, .tct15, .tct16, .tct17, .tct18, .tct19, .tct20, tct21, tct22, tct23

On the old computer, you will need to find the tax return files for the appropriate years and copy them on to a USB stick or removable memory device of some kind.

You can search for these files but it might be easier to see where the files have been saved by starting the TaxCalc program on the old PC and selecting the file on the returns page. The file location will be shown in the Progress Monitor.

Once you have copied all the files you wish to transfer, take the removable memory device to the new computer and copy the files into a folder of your choice (normally a sub-folder in Documents).

Start TaxCalc, click on File > Open and browse to the folder where you have loaded the tax return files and select the file you wish to use. When you next start TaxCalc, the file will be listed.

Repeat this process for different files and years as required.

If you need to move files to the 2013, 2014 or later iterations of the TaxCalc program, please refer to the following link for more information:
