Learn about tax lots, multiple transactions, and how total costs are calculated when entering cost basis information for your transferred securities.
What is a lot?
A lot is a record-keeping method that tracks the purchase date, sale date, cost basis, and quantity for each security in your portfolio, even when multiple trades occur in the same security.
A lot represents shares, contracts, or other units traded together in a single transaction.
How can I edit position cost basis?
If you bought all shares in one transaction:
- Click 'Add Lot'
- Enter total quantity, Acquisition Date, Total Cost, and Currency
- Click Continue when finished
If you bought shares through several transactions:
- Click 'Add Lot' for each transaction
- Enter quantity, Acquisition Date, Total Cost, and Currency
- Repeat for each transaction
- Click Continue when finished
Note: Total quantity across all lots must match transferred securities.
What is the total cost?
Total cost represents the complete cost basis of a transaction, including:
- Original purchase price
- Commissions and fees
- Corporate action adjustments
Example: 100 shares of ABC at $30/share plus $5 commission = $3,005 total cost
