Troubleshooting

Generally, this error is caused by associating a T4 with the wrong Relevé 1. This occurs when the person has, for example, 2 T4s and 2 Relevé 1s, or when the employer has submitted 2 T4s but only one Relevé 1.

If you are in the situation where you have 2 T4s and 2 Relevé 1s, please make sure you have correctly associated the Relevé 1 with the correct T4. You may want to try deleting the slips and re-entering them to make sure that the T4 for the Ontario job is not being associated with the T4 that came with the RL1.
