Understanding Harvest Rules

What is a Harvest Rule?

Harvest Rules define the criteria used to identify harvesting opportunities.

Rules can evaluate:

  • Dollar gains/losses

  • Percentage gains/losses

  • Long-term vs short-term positions


Rule Types

Position-Level Rules

Evaluates the entire position.

Best used for:

  • Non-VSP custodians

Lot-Level Rules

Evaluates individual tax lots.

Use lot-based rules when the loss or gain of specific tax lots should be used to determine if a position meets the rule criteria.

Both

Evaluates positions and individual tax lots

Selecting both does no harm: accounts at custodians that allow lot-level orders via FIX present lots for selection, and accounts at custodians that do not allow lot-level orders via FIX present the total harvest quantity.


Best Practices

Dollar-Based Rules

Best for:

  • Precise tax targeting

Percentage-Based Rules

Best for:

  • Scaling across different account sizes

Important Consideration

Position-level and lot-level rule logic will impact which rule type best executes your tax strategy.
