Typically a bank wants to see a p&l and balance sheet that match as well as tax returns. I've never included estimated taxes on our balance sheets or p&ls since all ours are pass-through entities.
However, if it was a c-corp balance sheet, I probably would as that technically is a current liability. Although they will probably also ask for the tax return, so you might be able to get away with leaving it off the balance sheet for bank purposes.
