Tiller’s Estimated Quarterly Tax sheet can be added to any existing Tiller-powered Google Sheet that has a Categories sheet using the Tiller add-on for Google Sheets. The Est Quarterly Tax sheet leverages the Transactions and Categories sheet in your existing Tiller Google Sheet. It also leverages a Tags column in the Categories sheet, which will be added to the Categories sheet upon install of the estimator sheet if it doesn’t already exist.
If you don’t see it in the add-ons menu at the top of your Google Sheet, install the Tiller add-on.
Choose Add-ons > Tiller > Other Solutions > Tax Tools to open the sidebar.
Choose “Create” under the Estimate Quarterly Taxes heading to add the Estimated Quarterly Tax sheet to your Tiller Google Sheet.
You should see a new tab appear in your Google Sheet called “Est Quarterly Tax”
