User guide

• Before using Dobkapapp you will need to configure your brokerage account to send daily activity statements via email. This is how to do it for Interactive Brokers:

• Download and install a Dobkapapp binary suitable for your platform

  • If you using macOS and see an error such as 'App is damaged and can't be opened', it could be because the binary is quarantined. Try opening the terminal and running a command like xattr -d com.apple.quarantine /path/to/dobkapapp.app.

• Open Dobkapapp

• Configure mailbox settings and taxpayer settings

  • Initially the mailbox date cursor will be set to today. Move this a few days into the past (depending on how many days of activity statements you would like to process on the first sync)
  

• Add an importer and configure importer settings

• Dobkapapp now has all the information it needs. Click 'sync' to download and process activity statements

• Go to the 'filings' tab to see tax filings produced by Dobkapapp. Click 'Save as' to export a filing ready to be uploaded to ePorezi

• Use the status dropdowns to keep track of which filings have been filed and paid

• Next time you open the app, simply click 'sync' again to process new activity statements. Dobkapapp should remember which activity statements it has already processed to avoid duplicate filings

• When a filing has been submitted to ePorezi, mark the filing as 'Filed' and enter the payment reference

  

• When a filing has been paid, mark it as 'Paid'
