As a non-accountant but a business owner, I've learned not so long ago that we can claim only 50% of GST for Meals and Entertainment. Ok.

I want to ask the community what is the PROPER way to enter these expenses and GST?

Some suggest creating a custom tax rate that reflects the half (here in AB we have a 5% GST, so create a 2.5% GST). Then select the 2.5% GST for meals and entertainment expenses.

I consider this wrong because this is not the GST we paid. So, even though I am not an accountant, I believe that, for the sake of consistency, we still have to indicate the proper GST we paid (5%), while the system must automatically detect the Meals and Entertainment category as ITC = 50% of GST and calculate the tax credits respectively.

Please let me know if this feature is actually implemented already and I've just been living under the rock?

How do you do it?
