Before you begin

What if I do not have every file yet?

Start with the reports you have. GPMas identifies missing documents and details needing clarification. Add further files and answers in the same workspace.

What happens to my uploaded files?

GPMas processes your files and answers on its server in a temporary folder, which the application removes after handling the request. If you choose “Save on this device”, original files and answers are also saved in this browser. Read the privacy policy

Can I prepare a report for several investment accounts?

Yes. Add reports from your IBKR and Trading 212 Invest accounts. GPMas keeps each account’s figures separate and calculates one contribution balance across the accounts included in the report. Include all your declared investment accounts for a complete balance.

Does this cover my whole tax return?

GPMas prepares investment-account entries and dividend information from supported broker reports. Other income and personal tax circumstances may require additional entries in VMI EDS.
