How the Sales Tax Bad Debt Credit Calculator Works
Korea's VAT system lets businesses reclaim the VAT portion of unpaid invoices through a bad-debt tax credit. The U.S. has no federal VAT at all, so there's no direct equivalent -- but most states that impose sales tax offer a similar mechanism: when a retailer has already remitted sales tax on a sale that later becomes uncollectible bad debt (write-off under GAAP or IRS rules), the retailer can claim a credit or refund for the sales tax portion on a future sales tax return.
This calculator reconstructs that math using your state's sales tax rate: since the bad debt amount you enter includes sales tax, the credit is calculated by backing the tax rate out of the total (rate / (100 + rate)), the same logic Korea's 10/110 VAT formula uses at a 10% rate. Enter any amount you did recover to see the credit on just the uncollectible remainder.
Because there's no federal sales tax law, exact eligibility rules, documentation requirements, and filing deadlines are set state by state -- some states require the debt to be written off as uncollectible for federal income tax purposes first. Confirm your state's specific bad debt deduction procedure before filing a claim.
Frequently Asked Questions
No -- the U.S. has no federal VAT. Most states, however, let retailers claim a credit or refund for the sales tax they already remitted on sales that later became uncollectible bad debt, claimed on a future sales tax return.
Most do, but the exact rules -- deadlines, required write-off documentation, partial recovery treatment -- vary by state. Check your state department of revenue's bad debt deduction rules before filing.
