Sales Tax Audit Process in WA
The sales tax audit process in Washington is as follows:
- Sales tax audits begin when you receive a notice from the Washington State Department of Revenue.
- The auditors will schedule an initial meeting to address the nature of the audit.
- After the Department devises an audit plan, auditors will conduct an examination by reviewing your books and records and compare all reported sales to your state sales tax return. In general, auditors can look through three to four years’ worth of your documents to find any error.
- Once the examination phase is finished, the auditor will issue a final assessment. If you do not agree with the auditor’s findings, you may appeal or protest the assessment.
Not only can Washington Sales Tax Helper LLC handle the audit on your behalf and keep the auditors at bay while you concentrate on business operations, but we can also fight the assessment and protect your businesses’ rights. Do not wait to let us guide you through each step of the audit process.
