If you had a prior year debt and sent a payment then went ahead and filed your return that had a refund on it which they kept to pay off that same balance due then it may take months to process and the IRS to notice the double payment and refund the excess amount. If you file a joint tax return and your spouse sent a payment using her SS# then it could slow things up ... the IRS needs to line up the spouse payment to the primary taxpayer SS# on the joint return ... this has always been an issue with the IRS.
