A tax filing is mostly the act of restating what the year already says. IDup therefore starts it from the ledger rather than from a blank form.

Where to find itTax & accounting in the sidebar.

Step by step

  1. Open Tax & accounting → Dashboard for the current position.
  2. Check Invoices and Expenses from the same menu — these are the two sides the filing is built from, and this is the last chance to correct them.
  3. Open Tax report for the period you are filing.
  4. Start the filing under Tax declaration. It is prefilled from the figures; you complete what only you know.
  5. File it, then keep the result in Document archive, where it stays with the year it belongs to.
  6. Settings in the same menu holds the rates, the periods and the defaults.

If a professional files for you
