Recalculate sales tax on the affected transactions
Because the Washington state tax return filing period is open, you will need to complete this review and make any necessary changes on or before April 30,2019.
- To recalculate sales tax, import transactions, or recalculate from your accounting system.
- Next, re-bill your customer for the corrected 7.90% tax rate. You may also elect to absorb the undercharged tax and not re-bill your customers.
Note: You may choose not to recalculate tax due and report the tax charged and collected as-is. If you do make this choice, you risk an unfavorable audit and additional tax assessment, plus potential penalties and interest in the future.
If needed, contact your tax professional for guidance on how to report the undercharged tax.
