How GPMas prepares GPM311 investment-account figures

The calculation turns IBKR and Trading 212 reports into H-section entries, F-section dividend totals, interest rows, the remaining deposited amount and the EUR rates used.

Sources: VMI, Interactive Brokers, Trading 212 and ECB.

The core idea: your remaining deposited amount

This is the money you have added to the investment account, less withdrawals. A withdrawal means money taken out or paid from the account. If it exceeds the remaining deposited amount at that moment, GPMas flags the excess for review as potentially taxable income.

  1. For the 2025 GPM311 return, cash before the confirmed start day's operations and the purchase price (cost basis) of eligible pre-2025 investments may form the starting amount.
  2. For subsequent years under the regime, VMI uses the previous return's remaining deposited amount. An unknown amount cannot be assumed to be zero. GPMas currently supports uploaded reports for tax year 2025.
  3. Money added and net dividends added to the account increase the amount; withdrawals reduce it in chronological order.
  4. Interest reported as KL does not increase the remaining deposited amount. Other interest requires review of its type, payer and tax evidence before GPMas determines its treatment.

The order matters. Money added later cannot retrospectively offset an earlier withdrawal that exceeded the amount available at that time.

Who can use the investment account regime?

This guide is for Lithuanian tax residents who choose to use the investment account tax regime. The account must be declared to VMI, and the funds in it must be used for eligible investments. Check VMI's official guidance before relying on the regime for a particular account or product.

What you still enter in VMI EDS

GPMas prepares the account details, H-section entries and F-section dividend totals; it does not file your return. In VMI EDS, enter the financial institution, country, account identifier, account opening date and the date you began using it for investments. Check the calculated entries before submitting your return.

Transfers between investment accounts

VMI treats a transfer between your own declared investment accounts differently from money taken out for another purpose. Keep the source records for every transfer and verify the treatment in VMI EDS before filing, especially when more than one broker or bank account is involved.

Which broker files supply each figure?

IBKR

Annual Activity Statement

The source of dated cash events for deposits, withdrawals, interest, dividends and withholding, and for checking cash totals.

IBKR

2024-12-31 Activity Statement

The source for pre-2025 positions and, for a 2025-01-01 regime start, opening cash. Cash for a later start is established separately. You may omit this statement only after explicitly confirming that there was no opening cash or position.

IBKR

Dividend Report

Used to check countries and classifications and compare grouped dividend and withholding totals. Required when the Activity Statement contains dividend activity, unless you complete a documented country and classification review.

Trading 212

History CSV

The source for transactions, cash movements, dividends, interest and historical cost reconstruction.

Trading 212

Activity Statement PDF

Used to identify the Invest account and, where needed, compare opening cash and year-end position quantities with History data.

Account-specific rules are covered in the IBKR declaration guide and the Trading 212 declaration guide. For downloads, use the report guides for IBKR and Trading 212.

What do the H-section codes mean?

The codes are official GPM311 terms. GPMas explains their effect on the remaining deposited amount in plain language.

CodeMeaningEffect
ISPurchase price (cost basis) of eligible investments acquired before 2025 and added to the investment account.Increases the remaining deposited amount.
IACash in the account when it was declared as an investment account.Increases the remaining deposited amount.
IIMoney added to the investment account.Increases the remaining deposited amount.
PPWithdrawal: money taken out or paid from the investment account.Reduces the remaining deposited amount.
IVNet dividends added to the investment account.Increases the remaining deposited amount.
KLInterest on which Lithuanian or foreign income tax has been paid.Does not increase the remaining deposited amount.

Why dividends appear twice

Dividends retain their normal income-tax treatment. GPMas shows gross dividend income and foreign tax withheld by country for GPM311 F; the net amount added to the investment account is shown as an IV entry in H.

For IBKR, the Activity Statement supplies the dated dividend and withholding cash events. GPMas uses the tax-year Dividend Report to check countries and classifications and compare grouped totals. The two reports do not need matching rows for every payment. If the Dividend Report is unavailable, GPMas supports an explicit country and classification review using supporting documents. For Trading 212, dividend cash events come from the History CSV.

Which EUR rate is used for non-EUR operations?

GPM311 amounts are in EUR. GPMas converts each relevant non-EUR cash event using the ECB reference rate for its transaction date, retaining the source date for audit. This includes dividend and withholding cash events from the IBKR Activity Statement. Broker-reported EUR totals do not replace these individual conversions. If the transaction date has no ECB rate, the previous available rate is used and shown.

How is interest reviewed?

GPMas prepares KL automatically for clear IBKR cash interest with linked withholding tax. Other interest, including Trading 212 cash and share-lending payments, can require review of the income type, payer and evidence of paid tax. The broker's label alone does not establish the treatment.

Under VMI's GPM311 H instructions, section 55.2, KL covers interest on which income tax has been paid. GPMas shows gross interest and the supported tax amount separately, leaves the KL declaration date blank and excludes KL from contributions. If the export contains no withholding, GPMas does not automatically infer a KL entry; a reviewed decision requires supporting evidence.
