The swedish tax form for handelsbolag.
The contents of the form are generated using the tax codes specified in the chart of accounts. A list of tax codes, and how they are linked to fields in this form, can be found at www.bas.se. If you add a new account and it seems to be missing from this form, you can find the code at this link. Enter the code in the 'Accounts' view.
If you have an older chart of accounts, you can use the button 'Konvertera SRU-koder' to attempt to convert the tax codes to the correct setup.
