Do-io
What Do-io is
Do-io is a CPA-designed calculator for tax professionals preparing federal tax calculations and estimates. Its federal calculations focus on popular items on a tax return, and the maker says the tool is designed for conservative results and provides tips within the calculator. It does not cover every tax-return line or every possible credit, and users handle state tax estimates themselves. The calculator is available in a browser, as a Chrome extension, through a mobile app using OpenAsApp, or embedded on a firm website for clients to use. Firms can apply custom branding with the Custom Plan. Users can print calculation reports to PDF. The maker says the tool does not ask for names, addresses, Social Security numbers, or dates of birth and does not collect personally identifiable information. Users create a username and password; multi-factor authentication is not required. Options include a 25.00 USD one-week plan valid for 7 days, a Standard Plan at $249 a year, and a Custom Plan at $349 a year. Annual plans include a 7-day money-back guarantee. Scenario modeling is not included.
