Tax Prep Organizer Spreadsheet 2026: Tax Document Checklist, Deduction Tracker and Charitable Giving Log (Excel and Google Sheets)

A tax prep organizer spreadsheet for the 2026 tax year: a tax document checklist, a deduction tracker and a charitable giving log in one household file. Bring your preparer a list of every form you expect and which ones have arrived.

The Document Checklist lists 32 common forms (W-2, 1099s, 1098 mortgage interest, giving statements and more). Mark each one expected, received or not needed, and the percent-complete bar and missing-form count tell you what's still in the mail.

How it works

1. Open START HERE and set the tax year and a household label (a label, not names).

2. Mark forms on the Document Checklist as they arrive.

3. List each job, client, account or benefit on Income Sources.

4. Log possible deductions and gifts as they happen. Gifts at or above $250 are flagged for a written acknowledgment, and non-cash gifts over $500 are flagged to ask your preparer about Form 8283.

5. Record estimated payments by quarter.

6. Print the Preparer Summary (two pages in large, easy-to-read type) before your appointment.

Brokerage proceeds and 1099-K totals sit on their own line and stay out of total income, so they aren't counted twice.

What's inside (7 tabs): START HERE, Document Checklist, Income Sources, Deduction & Expense Log, Charitable Giving Log, Estimated Tax Payments, Preparer Summary.

Reuse it next year by changing the tax year cell. Works in Excel or Google Sheets on any device. No macros.

This is an organizational tool, not tax, legal, accounting or financial advice. It keeps your records in order. Your preparer decides what is deductible.
