Recover Overpaid Taxes

It is not uncommon for businesses with $100M+ in spend to overpay $500K in sales & use tax annually. This financial leakage negatively impacts your profit margins and also leaves your business vulnerable to recurrent and unnecessary internal mistakes.

What is a Reverse Sales and Use Tax Audit?

A reverse sales and use tax audit is the process of reviewing previous years of purchase data in an effort to find erroneous sales or use tax charges or accruals. Generally, these errors are due to a misapplication of tax laws by the seller or oversight of an exemption provided by the state.

How Far Back Does
a Reverse Sales Tax Audit Go?

The statute of limitations varies from state to state.  Some states, like NY, carry a three-year look back, while others, like NJ, have a four year-year lookback period. Additionally, clients going through a sales tax audit can have an extended lookback period to offset the current audit period.

How Often Should You Complete a Reverse Sales Tax Audit?

A typical reverse sales and use tax audit should be completed every 2-3 years.

Frequently Asked Questions

What is Sales Tax Recovery?

Sales Tax Recovery is the process of reviewing previous years’ of spend data for a company to find purchases that the seller charged erroneous sales tax on or the purchaser accrued erroneous use tax on.  Generally, these erroneous sales or use tax charges are due to a misapplication of the tax laws or due to overlooking of an exemption provided by the state.

What is the statute of limitations for filing a refund claim for overpaid taxes?

The statute of limitations varies from state to state. Some states, like New York, carry a three-year lookback, while others, like New Jersey, have a four-year lookback period.  If a company has an on-going audit, any period that the taxing authority has open under audit is also open for a Reverse Sales & Use Tax Audits (RSUTA).

What type of information do you need to complete an Reverse Sales & Use Tax Audit (RSUTA)?

To start Sales Tax Recovery you need a report that details all the purchases made by the company for the period in review, and you need access to the company’s ERP / invoicing system.  If you find refund opportunities, you may need additional information (i.e., vendor contract) to finalize a refund claim.

What are the general items you look to get refunds?

When performing a Reverse Sales & Use Tax Audit (RSUTA) most firms conduct a targeted review based on what industry a company operates in, but this is not how we perform a RSUTA.  We review all the company’s purchases and after determining the areas where the company has its largest spend we review the tax law to determine if there are any applicable exemptions. 


The most common areas we find refunds are in the review of purchases of:

Software – Tax laws around IT purchases (i.e. software) do not keep up with the speed at which new products are developed and brought to market.  Furthermore, some purchases by their very nature are challenging to tax correctly in all circumstances.

Construction/Interior Design Vendors – Many states provide exemptions on purchases that constitute as “capital improvement.” However, the definition of capital improvement varies from jurisdiction to jurisdiction, and rather than determine how to correctly tax each transaction, many vendors tax all transactions.

Promotional Material Vendors – Typically, states use the sourcing laws to determine how transactions should be taxed, allowing for purchases to be taxed based on the location of their final use.  However, most vendors incorrectly tax invoices based on where they ship their goods to, rather than their final destination for use.

How long does a Reverse Sales & Use Tax Audit take?

The initial process of data analysis, invoice review, preparation, and filing of the refund claim takes four to eight weeks. Once filed, the claim typically takes six to nine months to get reviewed and approved by the state.

Will submitting a refund claim trigger an audit?

In most cases, the refund claim will not trigger a sales tax audit. However, as expected, the refund claim will be reviewed in detail by the taxing authority. The amount of supporting documentation requested will vary from auditor to auditor.

Can the refund be used to offset a current Audit?

Yes, refunds can be used to offset audit assessments.  In addition to reducing the liability imposed, the offset lowers the amount on which penalties and interest are imposed, resulting in a significantly lower assessment.  In some cases, the refund amount is larger than the audit liability amount resulting in a net refund for the company.

Can we receive a refund directly from the vendor?

Yes, you can, but vendors are not required to give a refund directly to the company.  Even if the vendor is not going to give the company the refund in some states (i.e. Georgia) you are required to reach out to the vendor before you can reach out to the state to request a refund.

Can we request to no longer be taxed by this vendor?

Yes. If the reoccurring purchases from a vendor are deemed to be “exempt” then an exemption certificate can be furnished to the vendor for future transactions. 

How often should we complete this analysis?

A Reverse Sales & Use Tax Audit should be completed every two to three years.
