The Maryland Comptroller issued an interpretation of the Maryland Digital Advertising Tax (DAT) that excludes certain digital advertising from the DAT. A Maryland regulation – COMAR 03.12.01.01 – limits taxable “digital advertising services” to those “advertising services on a digital interface that are: (i) Programmatic; and (ii) Visually conveyed.” Thus, receipts from sales of digital advertisements that are audio only, and digital advertisements that are not transacted programmatically are excluded from the DAT. To the extent that a taxpayer included gross revenues from these sales of advertising, it should consider filing a refund claim.
The deadline to file a refund claim for the first year of the tax (2022 tax year) is “3 years from the date the tax, interest, or penalty was paid.” Tax-Gen. § 13-1104(a). We understand the Comptroller considers estimated taxes to have been “paid” on the date the annual return was filed. Thus, the three-year statute of limitations on refund claims is coming to a close for the 2022 tax year (i.e., three years from the filing of the 2022 annual return). Therefore, April 15 may serve as a deadline for certain taxpayers subject to the DAT. We note that several companies subject to the DAT are not paying the tax due to the pending litigation challenging the legality of the tax.
