# How to track capital gains tax records for property and shares

Source: https://wealthscout.app/updates/capital-gains-tax-records

To minimize capital gains tax, you must track your total 'cost basis.' This includes the original purchase price, legal fees, stamp duty, agent commissions, and capital improvements. Without permanent digital records of these costs, tax authorities will assume a lower cost basis, artificially inflating your taxable profit.

## Takeaways

- Your 'cost basis' is not just what you paid; it includes acquisition costs and capital improvements that reduce your final tax bill.
- Losing a contract or receipt from 15 years ago means paying tax on money that wasn't actually a profit.
- Modern brokerages track share purchases automatically, but tracking inherited assets and property improvements is entirely your responsibility.

**Scope.** Tax laws differ significantly by country, especially regarding inherited assets and primary residence exemptions. Always consult a local tax professional before executing a large sale.
