Stupid question. I have sinking funds but I keep the cash in my bank account (for when the bills are due {like for annual subscriptions}).Stupid question. I have sinking funds but I keep the cash in my bank account (for when the bills are due {like for annual subscriptions}). When filling out the budget by paycheck workbook, do I deduct those amounts? If so, then my balance doesn't match my bank balance. I'm so confused.
