Start with your situation
Create a separate sheet for each year. Start with what you actually know, then list amounts that need confirmation instead of treating an old bill as a complete account history.
Build the balance from its parts
The amount on a return, the amount on a bill, and today's account balance can differ. Payments, adjustments, penalties, and interest may explain the difference. IRS account information and payment history help identify what has posted. Keep each tax year separate so an older debt is not confused with a current obligation.
Reconcile one year at a time
Start with the return, add the agency's adjustments, and compare payments against confirmations and account activity. Record the date of each balance because figures can change. Flag missing payments with their amount, date, method, and confirmation number. Do not submit a second payment merely to make a spreadsheet agree before investigating the first transaction.
- List every affected tax year
- Save payment confirmations
- Date each balance snapshot
Questions to consider
Is an old letter the current payoff amount?
It may not be. Check current agency information, especially when interest, later payments, or adjustments may have changed the account.
