Thanks for posting in the Community, dorretti.

Can I ask what specific GST code and transaction are you trying to change? There was a reported product investigation last month about Unable to reclassify GST on deposit transaction. And the engineers mentioned that bulk edit of GST on purchases to sales type is not allowed in QuickBooks Online. 

If the transaction is of sales type and the user is trying to change it to a purchase type GST then it's not allowed.
But it's allowed from the actual QBO transaction page.

Deposit-type transactions are not considered purchase- or sale-type transactions, but once GST is assigned to a deposit-type transaction, it becomes a purchase- or sale-type transaction based on the GST type, and hence, changing tax type in bulkEdit is restricted.

If you still need more help with reclassifying your transaction. I recommend also checking in with our Customer Care Team. That way, they can check your transaction and ask for your details in a secure form.

Drop by again in the Community if you have other questions. 

Hello again

I am trying to change from GST on non-capital to GST-free non capital so no, I am not trying to change sales amounts.  I can't put GST on expenses in any way if it was blank either. 

This sentence is a bit daunting - how can a deposit ever turn into an expense if that is what you are saying.  

Deposit-type transactions are not considered purchase- or sale-type transactions, but once GST is assigned to a deposit-type transaction, it becomes a purchase- or sale-type transaction based on the GST type, and hence, changing tax type in bulkEdit is restricted.

Why are income related GST codes showing in the reclassify tool if they aren't intended to work?   Why would this not come up in the knowledge base which had no articles at all on this issue?

Your answer isn't giving me confidence that the tool is being supported. 

Thank you for the information, dorretti.

The information below is just based on the product investigation made by the team about reclassifying GST free sales to GST 10% sales. If this is not the same with what you are trying to reclassify. I would recommend contacting our Customer Support through Chat or Phone. That way, one of our support agents can take a look in your account and the transaction you wanted to change in a secure form.
