Organizing Your Personal Taxes in Google Sheets 

First, categorize your transactions for taxes.

If you’re brand new to Tiller Money, you’ll notice it imports about 90 days of financial transactions and balances. To get a full year’s worth of transactions, you’ll need to manually add the rest of your data.

You can easily do this by exporting a CSV from your bank, and then using these steps to format and organize it for use in your Tiller Money transactions sheet.

Expenses By Category

Once you’ve got your historical data in your Transactions sheet it’s time to start categorizing it.

If you haven’t refined your categories yet, spend a little time on your Categories sheet thinking through how you spend and earn.

If you’re in a pinch to prep your data for your accountant, just focus your categories on how they break out into tax-related spending/earning.

Once you’ve got all the relevant data categorized, it’s time to build your reports.

Itemized Deduction Reporting via Category Rollup Template

If you prefer to use an itemized deduction amount on your tax return vs the standard deduction you can use the Category Rollup report to get a detailed analysis for your tax-deductible spending. 

  1. Tag your tax-deductible categories as “Tax” on the Categories sheet.
  2. Run the Category Rollup report with the “Only categories tagged Tax” option

This will generate a report that summarizes your transaction details organized by type (Income, Expense, Transfer), Group, and then Category for a selected date range for all your transactions using categories tagged as Tax.

If you’re not sure if you should itemize, consult with an accountant or tax advisor. You can easily export or print the report to send to your accountant (see below).

Visualize Your Yearly Category Spend with an Easy Pivot Table

If you need to quickly see the total amount spent or earned for a specific set of categories for the entire year for tax reporting, you can do this easily with a pivot table by year in a Google Sheet.

You can easily filter this pivot table to show you only what you need to see for your tax preparation and share this report with your accountant.
