Tennessee Department of Revenue Sales Tax Audit Protest

The situation

Marcus, 52, owns a chain of three Nashville-area convenience stores under the brand "Nashville Quik Mart." Total revenue across all three locations: $4.2M/year. In February 2026 he received a TDOR Notice of Proposed Assessment: "Sales and Use Tax: $67,400 (penalty of $10,110 + interest of $5,800 = $83,310 total), tax period: 2022-2024."

The assessment wasn't generated by an audit of his registers. It was generated by Tennessee's Retail Accountability Program: TDOR compared Marcus's wholesale beer/wine/tobacco/grocery purchase records (reported to TDOR by his distributors) against his reported taxable sales and found what it computed as a $381,000 shortfall in taxable sales over the three-year period.

Marcus has 30 days from the notice date to request an Informal Conference, or the proposed assessment becomes final.

(a) The RAP methodology almost certainly has incorrect assumptions. TDOR's RAP calculation uses an "expected markup" for convenience stores based on industry averages. But Marcus's three stores are in high-competition price-sensitive Nashville suburban locations where he operates on thin margins (especially on cigarettes and beer, which are highly competitive). His actual markup on tobacco (one of his highest-volume categories) is significantly lower than the TDOR average. Additionally, convenience stores have documented inventory shrinkage: employee theft, shoplifting, spoilage, and delivery discrepancies typically account for 1.5-3% of inventory at convenience stores, which TDOR's RAP calculation does not adequately account for. A properly documented shrinkage analysis + actual margin-by-category analysis reduces the implied taxable sales gap substantially.

(b) The food rate split is almost certainly misapplied. Marcus sells a mix of taxable-at-7% items (hot prepared foods, roller grill hot dogs, egg rolls, coffee, hot bar items) and taxable-at-4% items (cold packaged grocery food, sealed chips, candy bars, cold sandwiches in manufacturer packaging). If TDOR's RAP calculation applied the full 7% rate to all food items in Marcus's stores, it overstated the taxable base for the 4%-rate packaged grocery food. The Informal Conference must document the revenue breakdown between 7% and 4% categories.

(c) A Nashville tax attorney quoted Marcus $8,500 for "informal conference representation across all three locations, penalty abatement request, and Chancery Court appeal preparation if needed." The informal conference request letter + RAP methodology rebuttal + food rate reclassification analysis + penalty abatement request is largely self-executable with the right structure.

Second portrait: Yolanda, 44, owns a Nashville-area restaurant (Southern Comfort Bistro) with $1.1M in annual revenue. She received a TDOR Proposed Assessment of $28,600 after a direct audit (not RAP-based) of her POS records. The auditor classified her automatic gratuity (18% service charge automatically added to all tables of 6+) as part of taxable restaurant sales, correctly taxable, but then ALSO found a separate discrepancy: the auditor classified 8% of her food sales as subject to the full 7% rate when Yolanda argues they qualify for the 4% reduced rate (she sells pre-packaged manufacturer items, sealed chips, candy, bottled beverages, at a small market station near the restaurant entrance).

What Yolanda doesn't know: Tennessee's reduced 4% rate DOES apply to sealed manufacturer-packaged food items sold from her market station, even when sold in a restaurant context, as long as the items are cold, in original manufacturer sealed packaging, and not sold with utensils. The auditor appears to have applied the 7% restaurant rate to ALL food sales from her location. The formal distinction: the 4% rate applies to "food and food ingredients" in "original state", cold sealed manufacturer packages qualify even when sold at a restaurant. Yolanda's sealed packaged sales (approximately $87,000/year) should be reclassified from 7% to 4%, reducing the assessment by $26,100, nearly the full assessment amount.

Who receives this

Tennessee small businesses receiving TDOR Sales and Use Tax Proposed Assessments. Primary segments: (1) Tennessee convenience stores, gas stations, and grocery stores subject to TDOR's Retail Accountability Program wholesale comparison (most common source of TN sales tax assessments outside of direct field audits); (2) Tennessee restaurants with food rate misclassification disputes (4% vs. 7%) or service charge vs. tip disputes; (3) Tennessee retailers and e-commerce sellers with sampling methodology disputes. Geographic concentration: Nashville (Davidson County), Memphis (Shelby County), Knoxville (Knox County), Chattanooga (Hamilton County), Tennessee's four major metro areas.

Why the agency will not advise you

TDOR cannot advise audit respondents on how to rebut the RAP methodology or challenge the 4%/7% food rate split. TNTAP (the TN taxpayer access point) handles compliance, payment, and account management only, no protest strategy. The Retail Accountability Program is a uniquely TN enforcement tool with no analogy in the other 10-state sales tax suite: it's a wholesale-to-retail comparison that generates assessments without auditing the retailer's actual POS records. The rebuttal requires industry-specific markup and shrinkage data that no free public tool provides.

Key facts, with sources

• The Tennessee Department of Revenue (TDOR) issues a Notice of Proposed Assessment when an audit concludes that additional sales and use tax is owed. The taxpayer has 30 days from the date of the notice to request an Informal Conference with TDOR's hearing office. If no informal conference is requested within 30 days, or if the request is untimely, the proposed assessment automatically becomes a Final Assessment on the 31st day, the right to contest is permanently waived. The Informal Conference is an informal meeting with TDOR's hearing office (not a formal court proceeding); the taxpayer can present documentation and arguments to challenge the proposed assessment. After the Informal Conference, if the taxpayer is still dissatisfied, they can appeal TDOR's final determination to the Tennessee Chancery Court (within 30 days of the final determination). Tennessee has no dedicated state tax court, Chancery Court (a general-purpose equity court) handles state tax appeals. TDOR's problem Resolution Office (PRO) is available for taxpayers who have already received a final assessment and believe they were treated improperly, it is an internal TDOR ombudsman, not an independent appeal body.

• Tennessee operates the Retail Accountability Program (RAP), a uniquely broad enforcement tool that cross-references data reported by WHOLESALERS (distributors, suppliers) with the taxable sales reported by their retail customers. Under RAP, wholesalers report their sales to each retail customer to TDOR (similar to a Form 1099 requirement for sales volumes). TDOR then compares the implied taxable revenue (wholesale purchase volume × expected retail markup) against the retailer's reported taxable sales. If a retailer's reported taxable sales are significantly below what the wholesale purchase volume implies, TDOR initiates an audit under the RAP program and issues a Proposed Assessment based on the RAP-implied taxable sales shortfall. The RAP program was announced as producing significant compliance results in an October 2024 TDOR/Comptroller news release. The RAP methodology is the Tennessee equivalent of Georgia's alcohol markup audit (GDOR cross-references alcohol distributor data with bar/restaurant reported sales), but broader, applying to ALL retail businesses that purchase from wholesalers. Convenience stores, grocery stores, restaurants, and general retailers are all subject to RAP. The protest must demonstrate that: (a) the actual retail markup for the specific business is lower than TDOR assumed (commodity retailers have lower markups than TDOR's default); (b) actual inventory shrinkage, waste, and theft are higher than TDOR's default allowance; (c) the retailer's actual POS/register records show the true taxable sales, not TDOR's wholesale-based estimate.

• Tennessee's Sales and Use Tax has two state rates for food items, creating a common misclassification pattern in audits: (1) REDUCED 4% STATE RATE: applies to 'food and food ingredients' defined as substances, whether in liquid, concentrated, solid, frozen, dried, or dehydrated form, that are sold for human consumption and are consumed for their taste or nutritional value (Tenn. Code Ann. § 67-6-228). This reduced rate applies to grocery food items, unprocessed foods in original packaging, cold prepared foods in sealed packaging (manufacturer-packaged). Local sales taxes apply on top of the 4% state rate (local rates vary by county, typically 2.25-2.75%); combined rate is approximately 6.25-6.75% for qualifying reduced-rate food items. (2) FULL 7% STATE RATE + LOCAL RATES: applies to 'prepared food', food sold in a heated state or heated by the seller; food sold with utensils provided by the seller; food sold as part of a combination package where less than 50% of the selling price is for cold, unheated food; and restaurant meals generally. Combined rates on full-rate food items in Nashville (Davidson County): 7% state + 2.75% local = 9.75%. Restaurant audits frequently involve disputes where TDOR auditors apply the 7% full rate to items the restaurant argues should be at the 4% reduced rate (cold packaged items sold from a restaurant counter, for example). TDOR Revenue Ruling 13-01 provides specific guidance on the 4%/7% food classification.
