Can we show some sort of identification for ITC which we had already claimed. So that while calculating ITC, it will be easilier to have only unclaimed ITC

You've got me here to Input Tax Credit today, @devang1.

At this time, there isn't a way to identify whether the ITC has been claimed already or not. These are all listed in the system. For you to recognize if it was claimed or not, you'll need to open the tax liability manually.

I can see the importance of having this ability for you and your business. I'd like to let you know that the program is always open to changes to improve the product and cope with your needs.

That said, I encourage you to visit our QuickBooks Online Blog site to be updated with our latest improvements and product road-maps.

Lastly, you can always utilize this article attached to give you more tips in managing ITC in QBO: Input Tax Credit under GST.

I got your back if you have any other concerns, @devang1. Feel free to notify me by leaving a reply below. Take care!
