California restaurant sales-tax audits can create substantial exposure when a restaurant does not maintain detailed records. A recent California Office of Tax Appeals opinion, MPAAKINC, dba Anandabhavan Biryamhut, 2026-OTA-369, illustrates several recurring audit risks for restaurants: unreported taxable sales, the California 80-80 rule, sales of cold food, and the consequences of incomplete books and records.

OTA’s July 2026 business tax opinion list identifies MPAAKINC as a nonprecedential decision involving unreported taxable sales, the restaurant 80-80 rule, sales of cold food, Revenue and Taxation Code section 6359, Regulation 1603, and the submission of hallucinated or fictitious citations.

For restaurant owners, operators, bookkeepers, and investors, the larger issue is straightforward: once records are incomplete, CDTFA may reconstruct taxable sales using indirect methods. That can leave the taxpayer defending against an assessment built from bank records, federal gross receipts, markups, observation tests, point-of-sale summaries, or other available data rather than the taxpayer’s own reliable books.

California taxpayers often assume that if they overpaid tax, the state should refund the money. In practice, refund disputes frequently turn on procedure, not the merits. A taxpayer may have a legitimate overpayment, but if the claim is filed late or the taxpayer cannot prove timely filing, the California Franchise Tax Board may deny the refund without reaching the substantive tax issue.

A recent California Office of Tax Appeals opinion, R. Ardire, 2026-OTA-366, illustrates the risk. The case involved an amended California return that FTB treated as filed after the refund-claim deadline. The taxpayer produced an envelope bearing a private postage-meter date, but OTA concluded that the taxpayer had not carried the burden of proving timely filing.

The decision is nonprecedential, but it is still a useful warning. OTA’s July 2026 opinion cycle included many refund statute-of-limitations decisions under Revenue and Taxation Code section 19306. The pattern is clear: California refund deadlines are strict, and taxpayers should not assume that FTB or OTA will overlook timing defects because the refund appears substantively justified.

The IRS has announced a significant change to federal penalty relief. On July 8, 2026, the IRS introduced a new Automatic Exemption from Penalty program, commonly referred to as AEP, that will begin replacing the longstanding First Time Abate process for eligible taxpayers. The IRS states that the new automatic penalty relief process begins in summer 2026 and is intended to reduce the need for taxpayers to affirmatively request administrative penalty relief.

For individuals, businesses, payroll-tax filers, and tax professionals, this is an important procedural change. Under the prior First Time Abate framework, many taxpayers qualified for relief but did not receive it because they did not know to ask, could not reach the IRS, or did not understand the available administrative relief procedures. The National Taxpayer Advocate described the new automatic process as a taxpayer-rights improvement because eligible taxpayers will no longer need to contact the IRS to request first-time penalty relief.

The new program may help many taxpayers. But it does not eliminate the need to review IRS notices carefully. AEP has eligibility rules, covered penalties, excluded returns, and transition-period issues. Taxpayers should not assume that every IRS penalty will be removed automatically.

California taxpayers often focus on whether they overpaid tax. That is understandable, but in a refund dispute, being right on the numbers is not always enough. If the refund claim is filed too late, the California Franchise Tax Board may deny the claim without ever reaching the merits.

Recent California Office of Tax Appeals opinions reinforce that point. OTA’s June 2026 franchise and income tax opinions include J. Lord and D. Lord, 2026-OTA-304, a nonprecedential decision involving the statute of limitations on a claim for refund under Revenue and Taxation Code section 19306. OTA’s June 2026 list also includes many other refund statute cases, showing that missed refund deadlines remain a recurring problem in California tax controversy.

For California tax purposes, moving out of the state is important, but it is not always enough. The Franchise Tax Board may examine whether the taxpayer truly changed domicile, whether the taxpayer remained a California resident, whether the taxpayer’s absence from California was temporary or transitory, and whether any income remains California-source even after the move.
