TL;DR - Quick Summary
- Who it is for: US taxpayers, business owners, and tax preparers turning a year of bank statements into an organized tax workbook.
- Method: Add Category, Tax Line, and Receipt columns, then total each tax line with a pivot table or SUMIFS for Schedule A, Schedule C, or Form 8829.
- Key tip: Convert the following January's statement too, so December checks that cleared late are not missed.
- Watch out for: transfers between your own accounts, which get counted twice unless both sides are labelled Transfer and excluded from totals.
- Start: Convert each month with the PDF to Excel converter and leave the original Date, Description, and Amount columns unedited.

How do I combine 12 monthly statements into one Excel sheet?
Convert each month to CSV or Excel and save the files in one folder. In Excel, go to Data, Get Data, From File, From Folder, choose that folder, and click Combine. Power Query stacks every file into one table and adds the source file name, which you can keep as a month label. When you add next month's file to the folder, Refresh pulls it in.
How do I stop transfers between my own accounts from being counted twice?
A transfer from checking to savings shows up as a withdrawal in one statement and a deposit in the other. Add a Category column, label both sides as Transfer, and exclude that category from your totals. If you use SUMIFS for category totals, a Transfer category simply never appears in your deduction lines. Credit card payments from checking should get the same treatment when you also track the card itself.
Should I use a pivot table or SUMIFS for category totals?
A pivot table is faster for a one-time year-end summary. Select the table, choose Insert, PivotTable, put Category in Rows and Amount in Values, and you have totals in a few clicks. SUMIFS is better for a summary sheet you reuse each year, because the layout stays fixed and lines up with the tax form categories you care about.
Building a tax-year workbook from your statements
- Convert January through December, plus the following January's statement so you can see checks written in December that cleared late.
- Combine the files with Power Query from a folder, then format the result as a table with Ctrl+T so formulas and pivots expand automatically.
- Add Category, Tax Line, and Receipt columns to the right of the bank data, and leave the original Date, Description, and Amount columns unedited.
- Summarize by Tax Line with a pivot table, so each total maps to a line on Schedule A, Schedule C, or whichever form your preparer uses.
- Prove the workbook by checking that total deposits minus total withdrawals for each account equals the change between its January opening and December closing balance.
Keep the bank columns untouched
Do all your categorizing in columns you add, never by editing the date, description, or amount that came from the statement. If a figure is ever questioned, you want to show that your spreadsheet totals trace back to the bank's numbers without changes. Notes like business purpose or who attended a meal go in a separate Notes column.
