Prepare and file a tax return
IDup compiles the documents for your tax return from the books, shows the deadlines and hands the package to your accountant.
A tax filing mostly restates what the year already says. IDup therefore starts from the ledger. You file with your tax authority. IDup does not submit for you.
Step by step
- Open Tax returns → Overview. It shows the returns and deadlines for your country.
- File VAT under VAT return. See The VAT return.
- Open Annual tax return. It shows the financial year, your country and the deadline. For Swiss companies the deadline comes from the canton.
- Click Create document package. IDup builds a ZIP with the financial statements and prior year, trial balance, general ledger, fixed asset register, receivables and payables, VAT returns, payroll journal and receipts.
- Click Hand over to accountant if someone prepares the return for you. They are told by bell and the hand-over is logged.
- File the return with your tax authority.
The package comes with a read-me that states the deadlines and that this is not tax advice.
Germany
For companies in Germany, ELSTER (Germany) is a separate entry in the menu.
Switzerland, more
For Swiss companies the annual tax return page also holds a reconciliation from the income statement profit to taxable profit, and a list of attachments. Under Year-end closing, the Cantons tab has a checklist for each canton. It contains only what an official source confirms. Missing items are marked not documented.
