Is CapEx an expense on the P&L or just an analysis consideration?

[Cameron Marmon]

I have done some searching, but I did not find the answer I was looking for on this topic. 

Lets just say I decide to set aside $300/month for 12 months and I show it as an expense on the P&L. 

Now it is tax time!

Is it proper for me to report an expense of $300/month on the P&L to build the CapEx Reserve or is CapEx something that is considered in an analysis to guess at cash flow, but not actually expensed unless something happens?

I suppose I am not confused about the importance or a particular method for CapEx. I am confused on how to account for it on the financials and if it is okay to count it as a monthly expense, especially if no CapEx event occurs.

It doesn't go on your P&L.

It's just setting money aside in your checking account. If you'd like you can have a separate bank account on your Balance sheet and transfer the funds to it each month. Then you are "accounting" for your savings on your personal financials- but there's no impact come tax time.
