I cannot open my TaxCalc file(s)

If you try to open a TaxCalc return and it will not open, the most likely reason is that you are trying to open it with the wrong year's program.

For each year’s returns, you need to perform File > Open using the corresponding year's software. Here is a list of the file extensions and final version number for each year:

File Program Final Version
.tcs13, .tcs14, .tcs15, .tcs16, .tcs17, .tcs18, .tcs19, .tcs20, .tcs21, .tcs22, .tcs23, .tcs24  TaxCalc 2013 onwards Current release

.s07 TaxCalc 2007 7.10.09
