Track Your Refund
Tennessee does not have a state income tax on wages, so there is no refund to track there. Filing in another state? Ask your Summit advisor and we will point you to the right tool.

Record Retention Guide
- 3 years for most tax records – the standard IRS statute of limitations for an audit.
- 6 years if you underreported income by more than 25% of what is shown on your return.
- 7 years if you are claiming a loss from worthless securities or a bad debt deduction.
- Indefinitely if you did not file a return, or filed a fraudulent one.
- 4 years for employment tax records, from the date the tax becomes due or is paid.
- Property records (home, investments, equipment) – keep until the period of limitations expires for the year you dispose of the asset, since you will need them to calculate gain, loss, or depreciation.
