BAD DEBT EXPENSE

I have a problem with the way QuickBooks proposes to handle bad debt when there is sale tax involved, and wanted to ask the community at large their thoughts.When an invoice includes sales tax, if the client writes the entire amount off to bad debt, that still leaves them liable for the sale tax, at least from the taxing authority?s perspective.So, if a client has an invoice for $109, where $9 is the sales tax amount, but the client writes off the entire amount of $109 to bad debt expense, then the general ledger is still going reflect $9 in sales tax payable; and when and if the taxing authority comes in for an audit, they?re going to see $9 in sales tax payable and want an explanation or want the money.Likes wise if the taxing authority for income tax comes in and reviews the client?s general ledger, and see they wrote off $109 to bad debt, thus reducing their taxable income by $109, they?re going to say the client wrote off $9 too much and want the income tax thereon.Now imaging doing this scenario multiplied for a hundred or so transaction in a calendar year, and the impact on the bottom from the taxing authorities can be significant.I noticed that QuickBooks only allows one entry at a time.So what I?ve done is entered two separate entries:1. Enter $100 to bad debt expense account2. Enter $9 to sales tax payable account.I don?t like this procedure as it results in double the journal entries, and wanted to know if anybody in the community has an easier solution.Thx
