What PORTAX is
PORTAX is paid Windows software for after-tax portfolio analysis, optimization, and asset allocation. Version 9.9 can analyze up to 100 assets across 120 periods, using intervals from daily to annual. Its models include margin trading, short sales, futures positions, and sub-portfolios for different tax and ownership structures. Users can supply daily asset-class price and return series, run Monte Carlo simulations incorporating skewness and kurtosis, and view histograms. An optimizer graph compares strategies from after-tax risk minimization through tax minimization across portfolio return targets. Internal tax tables cover top marginal individual and corporate rates in more than 50 countries and 193 tax jurisdictions, with custom time-varying rates available. Client-report wizards create reports in the software or export formatted workbooks to Excel. PORTAX Version 9.9 costs $89 a month for one user, plus USD 9 per additional user. PORTAX Plus costs $299 a month, plus USD 29 per additional user. Both require a one-month minimum subscription.
