Delaware · Tax Notices

Got a Delaware tax notice? Read it right, then act.

What the notice is — and which agency sent it — matters more than the title, and the deadline near the top matters most of all. TechBrot is a bookkeeping and advisory firm, working remotely; we help you tell a simple information request from a real assessment and reconcile the books to find out whether you actually owe what the state claims, then hand your CPA, EA, or tax attorney clean figures to respond with. We do not respond to notices on your behalf, do not represent you before the Division of Revenue or the Division of Corporations, and are not a registered agent.

State rule

Delaware rule: when a required return is not filed, the Director of Revenue estimates the tax from any available information and proposes it as a deficiency; reconciled books for that period are what replace the estimate with documented figures. Source: 30 Del. C. § 521.

§ 01 · The short version
§ The short version

Delaware tax notice help from TechBrot is the books side: we identify the issuing agency, notice type and deadline, reconcile the period, and hand your CPA, EA or tax attorney documented figures to respond with. If a return was never filed, the protest of the state’s estimate is generally due within 60 days of the notice’s mailing.

§ 02 · Know what you’re holding

Common Delaware business tax notices.

The issuing agency and the type are usually printed at the top. Match it here before you do anything else — the right response depends entirely on which notice this is. Identifying the type and deadline is where we start; your CPA, EA, or tax attorney responds.

Division of Revenue · Bill

A bill for tax due.

The Division of Revenue says tax is due — gross receipts, withholding, or corporate income — and is demanding payment. Interest and penalties accrue; left unpaid, it heads toward a lien. The books question: is the amount real, or does it reflect a return that didn’t reconcile?

Division of Revenue · Proposed Assessment

Proposed assessment with protest rights.

A proposed assessment carrying formal protest rights. The protest must be filed in writing by the deadline on the notice or it becomes final — that filing is your CPA or tax attorney’s to make, on reconciled figures.

Division of Revenue · Gross Receipts

Gross-receipts filing mismatch.

The receipts the state expected don’t match what was filed or paid — common when QuickBooks isn’t tracking receipts by business activity. A reconciled, activity-based gross-receipts workpaper often changes the number in question.

Division of Revenue · Withholding

Withholding tax mismatch.

Withholding reported doesn’t tie to payroll, or a withholding return is missing. Because withholding is trust-fund money, these escalate faster — reconciling payroll to the filings is the fix, and it starts in the books.

Division of Revenue · Request for Information

Request for documents.

The state wants documents to finish processing a return. Respond by the date noted to avoid an adjustment. Often the fastest to clear once the period’s records are organized and reconciled.

Division of Corporations · Delinquency

Franchise tax / annual report overdue.

A corporation hasn’t filed its annual report or paid the franchise tax, both due by March 1: the penalty for not filing a completed annual report by then is $200, and interest at 1.5% per month runs on any unpaid tax (Division of Corporations), and good standing is at risk. We confirm the reserve in the books and keep the share and gross-asset figures both methods use; your registered agent or CPA files.

Delaware gross-receipts, withholding, and corporate-income returns and payments are filed through the Division of Revenue; the franchise tax and annual report are filed through the Division of Corporations (typically via your registered agent). A return that wasn’t accepted or didn’t reconcile is a frequent trigger behind these notices. Always confirm the current process and deadlines against the issuing agency.

§ 03 · The most common root cause

Why so many Delaware notices are really books problems

When a return is filed from books that aren’t reconciled, the numbers drift from reality. The state’s systems cross-check what you reported against what it expects — and when those don’t line up, a notice goes out. Typical triggers are gross-receipts filings that don’t reconcile to the general ledger (often because receipts weren’t tracked by business activity), a return the state never received, withholding that doesn’t tie to payroll, and a franchise-tax reserve that was never tracked until the delinquency notice arrived.

The practical implication: before you assume a notice is correct and pay it — or assume it’s wrong and ignore it — get the period reconciled. Knowing your true number is what lets your CPA, EA, or tax attorney respond from a position of fact rather than fear. Reconciling that period is exactly the work we do.

When a required return is not filed, Delaware law has the Director of Revenue “estimate from any available information” the taxable amount and the tax, and notify you of the amount proposed as a deficiency (30 Del. C. § 521); a written protest against a proposed assessment is generally due within 60 days of the notice’s mailing (§ 523; check the date printed on your notice). From there your CPA, EA, or tax attorney chooses the path: a protest, an installment payment plan with the Division of Revenue, or, for a business the Division has not yet contacted about the returns, a voluntary disclosure agreement, under which the Division waives civil penalties but still bills interest. Every one of them rests on reconciled figures.

Records example: for a withholding notice, the Payroll Summary and Payroll Tax Liability reports for each affected quarter, reconciled to the Delaware withholding payable account in the General Ledger and to the W-2s issued; for back gross-receipts tax, the Profit and Loss by business activity for each period. The package is designed for CPA review; acceptance depends on the recipient’s requirements.

Trust-fund tax. Delaware tax withheld from wages is held as “a special fund in trust for the State Tax Department” (30 Del. C. § 1155), and a person required to collect, account for and pay over a Delaware tax who wilfully fails to do so is liable for a penalty equal to the tax not paid over (30 Del. C. § 535). That’s why a withholding or payroll notice is more urgent than it may look, and why getting the books reconciled quickly matters.

§ 05 · Questions

Delaware tax notice questions.

What does it mean if I got a notice from the Delaware Division of Revenue?

It depends entirely on the notice type — and the type matters more than the title. Some notices simply ask for documents to finish processing a return. Others assert that you owe money and start a clock on your right to protest (a proposed assessment). The first step is always to identify the issuing agency, the notice type, and the deadline printed near the top, then respond before it passes.

How long do I have to respond to a Delaware tax notice?

A response deadline is printed near the top of the notice, and it varies by type. For a proposed assessment you must file your protest in writing by that date to preserve your appeal rights. Confirm the exact date on your own notice against the Delaware Division of Revenue — missing the deadline doesn’t make the issue go away; it removes your options and lets the assessment become final.

What happens if I ignore a Delaware State tax notice?

It escalates. The Division of Revenue can secure a judgment and lien, levy bank accounts, and pursue collection, and an unpaid franchise tax can cost a corporation its good standing and push it toward void status with the Division of Corporations. Withholding-tax notices escalate fastest because that money is treated as held in trust. Acting on the first notice is always cheaper than reacting to a lien or a voided entity.

Can the issue be from a bookkeeping error rather than real tax owed?

Very often, yes. A large share of Delaware notices trace back to a mismatch — gross receipts that don’t reconcile to the books (often because receipts weren’t tracked by activity), a return the state didn’t receive, withholding that doesn’t tie to payroll, or a franchise-tax reserve that was never tracked. When the underlying books are clean and reconciled, many notices are resolved by simply showing the correct figures. That reconciliation is exactly what we do — your CPA, EA, or tax attorney then files the response that resolves the notice.

How does TechBrot help with a Delaware tax notice?

We work the bookkeeping side: reconciling the period in question, identifying whether the notice reflects a real liability or a books/reporting mismatch, and assembling clean, documented figures your CPA or tax attorney can use to respond. We don’t represent you before the state or file the protest, the franchise tax, or the annual report — we make sure the numbers behind the response are correct and defensible.

Should I call a CPA, a tax attorney, or my registered agent for a Delaware notice?

It depends on the notice. For a straightforward information request or adjustment, your CPA (with clean books behind them) is usually enough. For a proposed assessment, an audit, or anything with protest rights and real money at stake, a CPA or tax attorney should lead the response. A franchise-tax or annual-report delinquency is typically handled through your registered agent or CPA. In all cases, reconciled books make their work faster and your position stronger — and that’s where we come in.

What are my options if I’m behind on Delaware taxes?

Delaware has an installment payment plan with the Division of Revenue, a voluntary disclosure agreement for a business the Division has not yet contacted about the returns (civil penalties waived, interest still billed), a written protest of a proposed assessment, and curing a franchise-tax or annual-report delinquency with the Division of Corporations. Each is requested and filed by your CPA, EA, tax attorney, or registered agent, and each needs accurate numbers, which starts with reconciled books. We rebuild and reconcile those books; we do not contact the state or choose the path.

What happens if a Delaware return was never filed?

Delaware law has the Director of Revenue estimate the taxable amount and the tax “from any available information” and send a notice of the amount proposed as a deficiency (30 Del. C. § 521). That estimate becomes the number to disprove, and a written protest is generally due within 60 days of the notice’s mailing (§ 523; confirm the date printed on your notice). Reconstructed, reconciled books are how your CPA or tax attorney replaces the estimate with documented figures; producing those books is our part.
