3.2. Standard Objections (Use Sparingly and With Cause)
3.2.1. Outside stated audit scope. The request seeks documents for tax
year(s) or tax type(s) not identified in the audit engagement letter dated
[__/__/____]. State the claim-specific basis for narrowing the request
after counsel reviews the Director's examination authority under 30 Del. C.
§ 364 and any tax-specific provision; do not cite § 522 as examination
authority.
3.2.2. Beyond statute of limitations. The request seeks records for tax year(s) [YYYY] for which the assessment limitations period under 30 Del. C. § 531 has expired. Without prejudice to that defense, Taxpayer responds [as a courtesy / declines to produce].
3.2.3. Unduly burdensome. Compliance would require [specify hours / cost]. Taxpayer requests a Section [____] meet-and-confer to narrow the request.
3.2.4. Privileged. Documents responsive to this item are withheld on grounds of attorney-client privilege and/or work-product doctrine; see Privilege Log at Section 5.
3.2.5. Not in possession, custody, or control. After reasonable inquiry, Taxpayer does not possess responsive documents. Taxpayer identifies the following potential custodian(s): [NAME / ENTITY].
3.3. Affirmation

4.2. Statement of Facts
4.2.1. Taxpayer is [describe entity type, residency/commercial domicile, operations].
4.2.2. For tax year(s) at issue, Taxpayer filed Delaware Form [200-01 / 1100 / 1100S / W-1 / 9114W / OTHER] reporting:

4.6. Penalty Defenses
If the Division nonetheless proposes an assessment, Taxpayer asserts reasonable-cause relief from failure-to-file or failure-to-pay additions under 30 Del. C. § 534 because:

- The legal position taken had substantial authority and was disclosed on the return; and
- Taxpayer has a clean compliance history.
4.7. Conclusion
For the reasons set forth, Taxpayer respectfully requests that the Division close the audit with a "no-change" letter or, alternatively, propose an adjustment limited to [describe limited concession] without penalties.

§§ 522-523, the 30-day period for trust fund taxes, or the 120-day
period for other Chapter 11 taxes when the taxpayer is outside the United
States. Confirm which effective version and tax classification govern before
using the linked protest template (state_income_tax_protest.md).

10. DELAWARE PRACTICE NOTES
-
Auditor authority. Under 30 Del. C. § 364, the Secretary may cause an
examination of books, papers, records, or memoranda bearing on a return and
may use a summons for testimony and proof material to the investigation.
Section 522 instead governs when a proposed assessment becomes final if no
timely protest is filed. -
Confidentiality. Tax information is confidential under 30 Del. C. § 368; mark all submissions accordingly. Unauthorized disclosure is a misdemeanor.
- Mathematical errors. Section 528 governs notices and protests for mathematical or clerical error assessments; it does not create a general taxpayer bill of rights. Check the notice and the applicable protest deadline.
- Power of attorney. Delaware Form 2848-D is the proper vehicle. Federal Form 2848 is not automatically honored.
- Statute of limitations. Generally 3 years from the filing date (§ 531(a)); 6 years for omission exceeding 25% of gross income; no limit for fraud or non-filing. Consents to extend must be in writing and signed before SOL expiration.
- Records retention. Delaware does not specify a single retention period in the statute; the Division generally requires records "as long as their contents may become material to the administration of any tax" (parallel to IRC § 6001). Seven (7) years is the prudent minimum.
- Unclaimed property exposure. Many Delaware audits originate as unclaimed-property examinations under 12 Del. C. Chapter 11. These are administered by the Office of Unclaimed Property and follow distinct procedures (Voluntary Disclosure Agreements, SOS-VDA program). Do not commingle responses.
- Privilege. Delaware recognizes attorney-client and work-product privileges; the federal IRC § 7525 accountant privilege does NOT apply to state tax matters in Delaware. Engage counsel early to preserve privilege over CPA work product.
- Penalty matrix. Check applicable failure-to-file and failure-to-pay additions under 30 Del. C. § 534; § 535 covers fraud and other specified penalties. Under § 533(a), interest on an underpayment is 0.5% per month or fraction thereof, subject to that section's scope and exceptions.
- No state sales tax. Delaware imposes no general sales/use tax. "Sales tax" audits are typically gross receipts / occupational license audits under 30 Del. C. Chapters 21–29 (use the gross-receipts protest template for those disputes).

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.

Checked against the law it cites
The statutes this template relies on are listed under Legal authority.
