GPMas Beta Help
LT Unofficial

English guide

Lithuania investment account tax return (GPM311), without the spreadsheet archaeology.

GPMas reads broker reports and prepares a review summary for Lithuania's GPM311 investment-account workflow. It supports Interactive Brokers and Trading 212 files, while you retain control of completing and submitting your GPM311 return in VMI EDS.

Unofficial helper only. It is not tax advice and does not submit anything to VMI.

What the tool prepares

The tool recognises broker files, converts relevant non-EUR cash movements using ECB reference rates, and presents a review-oriented GPM311 summary. The statutory field codes remain in Lithuanian because they are the codes used in VMI EDS.

  • H-section entries for opening amounts, money added, withdrawals and net dividends added to the account.
  • Dividend totals by country for the GPM311 F section.
  • Interest, foreign-withholding and FX audit information where present in source files.
  • File-reconciliation checks and review flags for unusual data.

Files to have ready

For Interactive Brokers, upload an annual Activity Statement and, when you received dividends, the tax-year Dividend Report. For the first GPM311 return using the investment account tax regime, a 2024-12-31 statement may also be needed to establish opening data. Trading 212 uses its History CSV and, where needed, its Activity Statement PDF.

How to use the result

Review the source and warning sections first. Then use the generated entries as a checklist while completing your declaration in VMI EDS. GPMas does not transmit broker files or declaration data to VMI.
