Where can I see projected capital gains and their tax effect?

Open Detailed Cash Flow or select the relevant year in TIME MACHINE. Review the taxable-income breakdown and account gains alongside withdrawals and property sales. The downloadable Excel report provides the detailed tables too.

Capital appreciation is not the same as a realized gain. A non-registered investment can rise in value without its entire increase being realized that year. Selling holdings, rebalancing and capital-gain distributions can produce realizations. Book values therefore matter.

For gains already realized earlier this year, supply the pre-run year-to-date fields. For a future property sale, also check its cost, tax-treatment selection and principal-residence settings.
