Dear Director:

Pursuant to 30 Del. C. § 523, Taxpayer [TAXPAYER NAME] ("Taxpayer") hereby files this written protest against the Notice of Proposed Assessment dated [__/__/____] (the "Notice"), a copy of which is attached as Exhibit A. The Notice proposes additional Delaware personal income tax, interest, and penalties for the tax year(s) [YYYY][YYYY] in the aggregate amount of $[____________].


3. STATEMENT OF TIMELINESS

3.1. The Notice was mailed by the Division of Revenue on [__/__/____].

3.2. This protest is filed within sixty (60) days of the mailing of the Notice as required by 30 Del. C. § 523(a).

3.3. Taxpayer therefore submits this protest is timely, and the proposed assessment shall not become final under 30 Del. C. § 525 pending the Director's determination.


4. STATEMENT OF FACTS

4.1. Taxpayer is a [resident / part-year resident / nonresident] of the State of Delaware whose principal residence during the tax year(s) at issue was located at [ADDRESS].

4.2. Taxpayer timely filed Delaware Form [200-01 / 200-02 / 200-03 / 1100 / OTHER] for the tax year(s) at issue on [__/__/____], reporting total Delaware adjusted gross income of $[____________] and Delaware tax liability of $[____________].

4.3. [Describe the substantive facts: residency status, income sources, withholding, credits claimed, business activity, allocation/apportionment, etc.]

4.4. The Division of Revenue's Notice asserts [summarize each adjustment: e.g., disallowance of credit for taxes paid to another state under 30 Del. C. § 1111; reclassification of nonresident income; denial of itemized deductions; addition of unreported income from Form 1099 matching].

4.5. Taxpayer disputes each adjustment as set forth below.


5. GROUNDS FOR PROTEST

Taxpayer protests the Notice on the following grounds, each independently sufficient to require abatement:

5.1. Adjustment No. 1 — [BRIEF DESCRIPTION]

  • Issue: [Describe the specific adjustment.]
  • Taxpayer's Position: [Set forth the legal and factual basis for the taxpayer's reported treatment.]
  • Authority: 30 Del. C. § [____]; [regulation, ruling, or case citation].
  • Evidence: [Identify supporting documents — e.g., Forms W-2, 1099, brokerage statements, residency records, K-1s — attached as Exhibits B–[__].]

5.2. Adjustment No. 2 — [BRIEF DESCRIPTION]

  • Issue: [Describe.]
  • Taxpayer's Position: [Describe.]
  • Authority: [Cite.]
  • Evidence: [Identify.]

5.3. Penalties

5.3.1. The Division has assessed [failure-to-file / failure-to-pay / accuracy-related / negligence] penalties under 30 Del. C. § 533 and § 535. Taxpayer asserts that reasonable cause exists to abate all penalties because [describe — e.g., reliance on a competent tax professional, serious illness, casualty loss, ambiguous statutory provision, good-faith reporting position].

5.3.2. Taxpayer is entitled to penalty abatement consistent with Delaware's Taxpayer Bill of Rights principles incorporated in 30 Del. C. § 528 and the Director's published guidance, which require the Division to consider all relevant facts and circumstances before sustaining penalties.

5.4. Statute of Limitations (where applicable)

5.4.1. The Notice purports to assess tax for tax year(s) [YYYY], for which the three-year limitations period under 30 Del. C. § 531(a) expired on [__/__/____]. The proposed assessment is therefore time-barred.

5.5. Burden of Proof

5.5.1. While a notice of proposed assessment is presumed correct, the presumption is rebuttable. Taxpayer's documentary evidence and sworn statements herein meet and overcome that presumption.


6. REQUEST FOR ORAL HEARING

6.1. Pursuant to 30 Del. C. § 523(b), Taxpayer respectfully requests an oral hearing before the Tax Conferee or the Director's designee to present testimony and respond to questions.

6.2. Taxpayer requests a minimum of [____] days' notice of the hearing date and consents to a hearing held in person at the Carvel State Building, by telephone, or by video conference, as the Director may direct.


7. RELIEF REQUESTED

WHEREFORE, Taxpayer respectfully requests that the Director:

  • A. Withdraw the Notice of Proposed Assessment dated [__/__/____] in its entirety;
  • B. Alternatively, reduce the proposed assessment to $[____________] as supported by Taxpayer's evidence;
  • C. Abate all interest and penalties for reasonable cause;
  • D. Issue a written determination under 30 Del. C. § 524 setting forth findings of fact and conclusions of law on each disputed issue; and
  • E. Grant such other and further relief as is just and equitable.

8. RESERVATION OF RIGHTS

8.1. Taxpayer reserves the right to amend or supplement this protest, to submit additional evidence and legal authority before the Director's determination, and to petition the Delaware State Tax Appeal Board under 30 Del. C. § 544 within 60 days of the Director's adverse determination.

8.2. Taxpayer further reserves the right to seek judicial review in the Delaware Superior Court under 30 Del. C. § 331 following any adverse Tax Appeal Board decision.

8.3. Nothing in this protest constitutes a waiver of any defense, including statute-of-limitations defenses, constitutional challenges, or claims for refund of amounts previously paid.

11. DELAWARE PRACTICE NOTES

  • Statutory framework. Delaware's audit and protest procedures are codified in 30 Del. C. Chapter 5, Subchapter III (§§ 521–546). Personal income tax substantive law is in Chapter 11; corporate income tax in Chapter 19.
  • Protest deadline (§ 523). 60 days from mailing of the Notice of Proposed Assessment for most taxes; 30 days for withholding-tax assessments; 120 days for Chapter 11 taxes when the taxpayer is outside the United States. The deadline is jurisdictional.
  • Director's determination (§ 524). The Director issues a written determination by certified or registered mail, including findings of fact and adverse rulings.
  • Finality (§ 525). The determination becomes final 60 days after mailing unless the taxpayer petitions the Tax Appeal Board.
  • Tax Appeal Board (§ 544). Hearings are open to the public; the Board may affirm, modify, or reverse. Filing fees and form requirements are set by the Board's Rules (https://finance.delaware.gov/state-tax-appeal-board/rules-state-tax-appeal-board/).
  • Burden of proof. Before the Tax Appeal Board, the taxpayer generally bears the burden of proving the assessment incorrect by a preponderance of the evidence; however, in cases involving alleged fraud, the burden shifts to the Division.
  • Judicial review (§ 331). Appeal lies to the Delaware Superior Court in the county where the Tax Appeal Board hearing was held; notice of appeal must be filed with the Prothonotary within 30 days of the Board's order. Further appeal is to the Delaware Supreme Court.
  • Refund claims (§§ 542–543). A claim for refund disallowed in writing becomes final after 60 days unless protested. If the Director fails to act within 6 months on a refund claim, the taxpayer may treat it as deemed disallowed and proceed to the Tax Appeal Board.
  • Mathematical/clerical errors (§ 528). Notices issued for mathematical or clerical errors are subject to a 60-day protest window; the Division must abate the additional amount on timely protest until the underlying issue is resolved through the regular deficiency procedures.
  • Power of attorney. Use Delaware Form 2848-D to authorize a representative; Delaware does not automatically accept federal Form 2848.
  • Interest. Interest under 30 Del. C. § 533 continues to accrue during the protest. Consider depositing the disputed amount (a "deposit in the nature of a cash bond") to stop interest accrual without conceding liability.
  • No tolling on unrelated taxes. Filing a protest tolls collection of the protested amount but does not toll unrelated tax liabilities.

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.
