Massachusetts Department of Revenue Sales Tax Audit Abatement

The situation

Lisa, 43, owns a catering company in Boston, Lisa's Table LLC ($820K annual revenue), specializing in corporate lunch catering and private event catering. In February 2026 she received a MA DOR Notice of Intent to Assess: $24,400 in sales tax on catering services, plus $4,880 in penalties = $29,280. The auditor had reviewed 6 months of Lisa's invoices and assessed sales tax on everything labeled "catering", including drop-off grocery orders and canned/packaged beverage deliveries.

(a) Drop-off grocery orders are exempt. Lisa regularly delivers individually packaged sandwiches (in original state, cold, in sealed packaging) and canned beverages to corporate clients. These items are food sold in their original state for off-premises consumption, they qualify for the food exemption under MGL c. 64H §6(h). The auditor classified them as "catering" (taxable) because they appeared on catering invoices. But the legal classification depends on the nature of the food, not the invoice label. Lisa estimates $41,000 of her audited revenue was for these drop-off grocery items, potentially exempt.

(b) The penalty may be abated. Lisa had never received a prior MA DOR audit notice or assessment. Under MGL c. 62C §33, penalties may be abated for first-time violations with reasonable cause. Lisa's reasonable cause: she classified her deliveries using the same food/catering distinction recommended by her accountant in 2021, before the DOR issued updated guidance on the prepared-food vs. original-state distinction for catering companies.

(c) The $24,400 dispute qualifies for ATB Small Claims. Even if the pre-assessment conference fails, the $24,400 disputed amount qualifies for the ATB's Small Claims procedure (under $25,000 threshold), Lisa can represent herself at the ATB Small Claims hearing without hiring a tax attorney.

Second portrait: Kevin, 49, owns Newbury Street Clothes in Boston, a boutique clothing store specializing in women's apparel ($430K annual sales). In March 2026 he received a MA DOR Notice of Intent to Assess for $11,800 in sales tax on items "exceeding the $175 clothing exemption threshold."

Kevin's store sells items priced from $120 to $290. The auditor had treated each customer transaction as a single unit and taxed every transaction where ANY item exceeded $175, even transactions where most items were individually below $175.

What Kevin doesn't know: The $175 threshold is per-item, not per-transaction. A customer buying a $169 dress, a $162 blouse, and a $195 jacket should have only the $195 jacket taxed, the other two items are exempt. Kevin's transactions where the auditor assessed tax on entire purchases because one item exceeded $175 are incorrectly assessed. If Kevin has his POS records by item (not just by transaction total), he can dispute the per-transaction misapplication and eliminate roughly 65% of the assessment.

Who receives this

Massachusetts businesses receiving MA DOR sales tax Notices of Intent to Assess or Notices of Assessment. Primary segments: (1) Massachusetts restaurants, caterers, and food service companies (food vs. materials split). Secondary: any MA business receiving a sales or use tax assessment from MA DOR.

Why the agency will not advise you

MA DOR cannot advise audit respondents on how to build their abatement argument. The DOR Taxpayer Advocate is an internal office (not adversarial to DOR). MassTaxConnect handles form SUBMISSION but not defense strategy. edparsonscpa.com and CPA firms charge $3,000–$8,000 for audit defense; tax attorneys charge $8,000–$20,000 for ATB litigation. The per-item clothing exemption threshold and the prepared-food/original-state distinction are both codifiable, documented in DOR guidance, and deterministic, ideal for self-serve analysis.

Key facts, with sources

• The Massachusetts Department of Revenue administers the Massachusetts Sales and Use Tax under MGL c. 64H (sales tax) and MGL c. 64I (use tax). Massachusetts has a 6.25% state sales tax rate with no local add-on (unlike NY and IL). When a MA DOR field audit concludes, the auditor issues a Notice of Intent to Assess (NIA). The taxpayer has 30 days from the NIA date to request a pre-assessment conference with a DOR Appeals Officer. The conference provides an opportunity to present additional documentation and dispute the auditor's findings before a formal assessment is issued. If the conference fails or the taxpayer does not request one, DOR issues a Notice of Assessment (NOA). The taxpayer then has 3 years from the date of assessment to file an Application for Abatement (Form ABT) or via MassTaxConnect. MassTaxConnect provides the FORM SUBMISSION interface for the abatement application, but provides no guidance on how to build the argument, which items are incorrectly classified, or what exemptions apply. If the abatement is denied, the taxpayer has 60 days from the Commissioner of Revenue's Notice of Abatement Determination to appeal to the Massachusetts Appellate Tax Board (ATB). The ATB is a fully independent administrative tribunal of the Commonwealth, not part of MA DOR.

• Massachusetts has two signature sales tax exemptions that generate frequent audit disputes: (1) The clothing exemption under MGL c. 64H §6(k) exempts clothing items costing less than $175 per individual item. This threshold is per-item, not per transaction, a purchase of four items at $169 each is fully exempt even though the transaction total is $676; a purchase of one item at $176 is not exempt. Common audit errors: (a) auditors applying the $175 threshold to multi-item totals rather than per-item prices; (b) auditors classifying accessories (handbags, belts, scarves) as clothing when some accessories are taxable (shoes are exempt; watches are not). Retail clothing stores in Boston, Worcester, and Springfield regularly dispute audit sampling that misapplies the per-item threshold. (2) The food exemption under MGL c. 64H §6(h) exempts food and beverages sold for off-premises consumption in their original state (not heated/prepared by the seller). Taxable food includes food sold in a heated state, food sold with eating utensils, and food sold for on-premises consumption. Restaurant and catering audit disputes frequently involve: (a) pre-made sandwiches and wraps (sold cold = exempt? or sold ready-to-eat = taxable?); (b) catering packages (always taxable as prepared food) vs. delivered grocery items (potentially exempt); (c) bakery items sold warm vs. at room temperature.

• For disputes not exceeding $25,000 in tax per tax year (or per transaction), the Massachusetts Appellate Tax Board applies its Small Claims procedure (MGL c. 58A §7A). The Small Claims procedure is informal (no formal rules of evidence, simplified hearing format) and allows self-representation. The ATB's Small Claims Division is one of the most accessible independent administrative courts in the US, most small business disputes under $25,000 qualify, and the simplified procedure significantly reduces the barrier to formal independent review compared to states that require Circuit Court litigation. The ATB docketing fee is $50 (Small Claims) vs. $200 (Formal). The full Formal procedure applies to disputes exceeding $25,000 and follows formal hearing rules.

When to bring in a professional

Self-serve responses fit routine cases: clear facts, amounts a business can absorb, and a deadline still ahead of you. Bring in a licensed professional when the amount at stake is large relative to their fee, the facts are genuinely disputed, criminal exposure is possible, or the deadline has already passed. A short paid consultation to sanity-check your plan is often worth it even when you handle the filing yourself.
