Thank you for choosing TurboTax. The reason behind the variation in the difference is because all or part of your refund may have been used (offset) to pay off past-due federal tax, state income tax, state unemployment compensation debts, child support, spousal support, or other federal nontax debts, such as student loans.
While it can be a frustrating experience, it is fairly common for the Canada Revenue Agency (CRA) to make a tax return assessment that is different from yours.
The CRA collects and maintains your tax information, and they may already have some of your tax slips for the current year (for example, T4 slips submitted to the CRA by your employer,) as well as other tax-related information from previous years (such as carry-forward amounts, RRSP limits, etc.). When filing your taxes, the CRA considers all of this information in totality in making their assessment.
The reasons for these discrepancies may vary, and can range from very simple (typo or data entry error, forgotten slip, receipt, amount, etc) to complex (carry-forward amounts not included, accounting errors, etc).
Verifying the source of discrepancy between your NOA and the tax return you filed
In most cases, the CRA will explain how they calculated your tax refund or balance owing, and you can find this information on your Notice of Assessment (NOA), under the heading Explanation of changes and other important information. Compare the line numbers on your NOA and their corresponding values with those entered into TurboTax.
If you used the TurboTax online edition, use the printed or PDF copy of the tax return you filed using TurboTax or the detailed summary page of your tax return to do the comparison. If you used the TurboTax CD/download edition, switch to Forms methodto do the comparison. If you need clarification or have any concerns, contact CRA.
