Why Earlier Financial Years Matter For Tax Reporting

Earlier financial years can affect later tax reports because Navexa calculates each year from the portfolio history recorded before it.

Tax reports in Navexa are based on the trades, income, settings, and tax records saved in your portfolio.

That means an earlier financial year can affect a later one.

For example, earlier years can affect:

If an earlier year is incomplete, later-year tax figures may also be incomplete.

If your portfolio has several years of history, review older financial years first.

This helps Navexa build a cleaner tax reporting chain.

A useful workflow is:

Working from older years forward is especially useful if you are new to Navexa and have imported historical data.

Cost bases can carry forward across multiple financial years.

A cost base is the recorded cost of an investment, including relevant fees. Navexa uses this information when calculating capital gains or losses after a disposal.

For example:

The earlier purchase and sale history may still affect the remaining holding’s cost base in FY25/26.

If the earlier buy trade, sell trade, transfer, or adjustment is missing, the later tax report may not have the full history needed.

Partial sales matter because they leave part of a holding behind.

If you sell all units in a holding, the position is closed. If you sell only some units, Navexa needs to know which units were treated as sold and which units remain.

That earlier choice can affect future reports.

This is why Navexa may ask you to confirm the method used on earlier sales when preparing a later financial year.

For example, if you partly sold TLS in FY23/24 and still owned TLS in FY25/26, Navexa may need to know how that earlier sale was calculated before finalising FY25/26.

AMIT and annual tax statement records can affect tax reports beyond simple dividend income.

AMIT records may include capital gains components, foreign income, tax offsets, and cost-base adjustments.

If you hold ETFs, managed funds, or trusts, Navexa may ask for AMIT or annual tax statement data in the Finalise FY checklist.

If you are new to Navexa, you may need to enter AMIT records for multiple historical years before later reports are complete.

Capital losses can move from earlier years into later years.

If an earlier year creates or records an unused capital loss, Navexa can carry that loss forward into later Capital Gains Tax reports when available.

This is one reason earlier years need to be reviewed before later years.

For example:

Capital losses recorded in later years do not apply backwards to earlier years.

Locking a financial year for tax reporting saves that year’s tax report calculations in Navexa.

Locked years can give later years a clearer historical base.

If an earlier locked year later changes, Navexa may show that the year needs review. This can happen after changes to trades, AMIT records, dividends, holding history, tax settings, or historical losses.

If that happens, review the changed year before relying on later reports.

New Navexa users may see more checklist items than existing users.

This is common when a portfolio has several years of imported history.

You may need to:

This does not mean the current year is wrong. It means Navexa needs earlier records to create a more complete base for later reports.

Existing Navexa users may have fewer historical items to review.

If you have been maintaining your portfolio each year, earlier years may already have confirmed dividends, AMIT records, complete trade history, and locked tax calculations.

In that case, you may only need to review the current or recently ended financial year.

Navexa may ask about older years because earlier records affect the financial year you are reviewing.

This can happen when earlier trades, AMIT records, cost bases, partial sales, or carried-forward losses flow into later reports.

The earliest year may show as ready to lock because it is the first year Navexa can use as a starting point.

Locking or confirming the earliest relevant year can help later years calculate from a clearer base.

You can continue using Navexa without locking every earlier year, but unresolved earlier records may affect later tax reports.

If you are preparing a tax report, review any checklist items that Navexa shows for the selected financial year.

A later year may change if earlier data changes.

For example, editing an old buy trade, adding AMIT data, or recording a historical loss can update later cost bases, capital gains, or carried-forward loss balances.

Navexa provides portfolio tracking and tax reporting tools based on the data recorded in your account. Navexa reports are designed to help you review and organise your investment tax information, but your lodged tax return and tax records remain the source of truth.

Review your records and speak with a registered tax agent if you need advice about your circumstances.
