What is tax-loss harvesting?

Tax-loss harvesting is a strategy designed to maximise after-tax returns by selling investments at a loss to offset capital gains elsewhere. This means less tax paid and more capital to invest and potentially grow.

01 Detect Unrealised losses surface at every market dip. Every dip is a potential offset.
02 Harvest Losses apply against realised gains. Wash-sale aware replacements keep your exposure intact.
03 Compound Capital that would have gone to tax stays invested. Year on year, the delta grows.

Built by finance, for finance.

Designed with practitioners and tax specialists. Every output is auditable, defensible, and built on the actual rules. Not a black box.

  1. Tax-aware, not just tax-loss.

    We model wash-sale equivalents, holding periods, and replacement exposure. A loss harvested today does not become a loss tomorrow.

  2. Adviser-first workflow.

    Run a client portfolio in under sixty seconds. Set jurisdiction, tax bracket, and any capital gains you want to offset from outside this portfolio. Surface signals, not conclusions. Export a report your client can read.

  3. Private by default.

    Your client data does not train any model. Holdings stay encrypted in transit and at rest. SOC 2 controls in flight.

  4. Replacement exposure, baked in.

    Candidate replacements scored against wash-sale loss rules.

“Most tools are autopilots. Constantly rebalancing, zero control. A client portfolio, especially as you move up into private wealth and HNWI territory, is way more complex. Capital-gains events are more deferred, more varied than anything sitting in a brokerage account. That's where Lumvest's execution, pricing, and integrations make sense. You can tell it was built by finance professionals.”
