7. MISSOURI PRACTICE NOTES
- Strict 30-day AHC deadline. RSMo § 621.050.1 requires the petition to be filed with the Administrative Hearing Commission within thirty (30) days after the Director's decision is placed in the U.S. mail OR delivered, whichever is earlier. Despite occasional secondary-source references to 60 days, the statute and the AHC rules use 30 days. Use registered or certified mail to lock in the mailing-date filing rule under § 621.050.3.
- 60-day protest at the Department. Before reaching the AHC, a taxpayer must protest a Notice of Deficiency within sixty (60) days under RSMo § 143.631. Failure to protest converts the notice to a Final Assessment.
- Burden of proof. Under RSMo § 621.050.5, the taxpayer bears the burden of proof except as to fraud, transferee liability, and any increase in the asserted deficiency, where the burden falls on the Director.
- Statute of limitations on assessment. Generally three (3) years from the later of the return's due date or filing date under RSMo § 143.711, extended to six (6) years for omissions exceeding 25% of gross income, with no limitation in cases of fraud or non-filing.
- Refund claims. Income tax refund claims must be filed within three (3) years from the date the tax was due (including extensions) or two (2) years from the date paid, whichever is later — RSMo § 143.801.
- Appellate routing. Under Mo. Const. Art. V, § 3, the Supreme Court has exclusive appellate jurisdiction in cases involving the construction of the revenue laws of Missouri. Routine substantial-evidence challenges go to the Court of Appeals.
- Federal RAR conformity. Final federal adjustments must be reported to the Department within ninety (90) days under RSMo § 143.601. Late reporting can extend the assessment limitations period.
- Interest. Both deficiency interest and refund interest are computed under RSMo § 32.065 at the federal short-term rate plus three percent.
- Power of attorney. Use Missouri Form 2827 to authorize representation before the Department; the AHC requires a separate entry of appearance by counsel.

About This Template
Tax law covers the paperwork that documents income, deductions, disputes, and settlements with the IRS and state tax authorities. Protests, offers in compromise, installment agreement requests, and appeals each have their own forms, supporting documentation, and strict deadlines. Well-prepared tax correspondence is often the difference between a negotiated resolution and an enforcement action with levies, liens, or penalties.
