There is really no expiry date. If you don’t take CCA (Capital Cost Allowance) this year, then the amount remains in the UCC (Undepreciated Capital Cost) balance. The UCC balance will remain there until it’s used up, or you dispose of the asset.
If you aren’t claiming the CCA do you have to enter the vehicle info to begin with? If it’s not entered the return becomes higher, why? It shouldn’t affect it if it’s not claimed?
You do have to enter info like kilometres driven if you are claiming expenses other than CCA. If you have no additions/dispositions during the year, then you don’t really have to put in your CCA information.
As for why your refund is higher without CCA – did you dispose of a vehicle? Sometimes, when you sell an asset, you can end up with a CCA recapture, which means the remaining balance gets added to your income. If that’s not the case, please contact our phone support for more assistance. They can use Screen Look to view your return and help you figure out what is going on.
