What This Tax Is

Delaware's Gross Receipts Tax (GRT) is a tax on the total gross revenues of a business, regardless of source. Like Washington's B&O tax, it applies to gross receipts with no deductions for cost of goods sold, labor, interest, delivery costs, taxes, or other business expenses[^1].

Rates vary by business category — retailers, wholesalers, manufacturers, service providers, and other categories each have different rates. Most categories also receive a monthly exclusion that exempts a portion of receipts from tax.

Delaware has no sales tax, making the GRT the state's primary consumption-related business tax.

Multiple Business Activities

Businesses with income from multiple categories must file separate gross receipts tax returns for each activity type. Each activity is taxed at its own rate with its own exclusion[^1].

Surcharge

Delaware does not impose an additional surcharge on the GRT for high-grossing businesses.

Credits and Exemptions

Monthly Exclusion

Each business category has a monthly exclusion amount — receipts below this amount are not taxed. The exclusion resets each month (or quarter for quarterly filers). Exclusions range from $10,000 (wholesalers) to $1,250,000 (manufacturers)[^2].

Exempt Transactions

• Out-of-state shipments where the seller ships directly to the customer outside Delaware[^1]
• Wholesale sales picked up in-state with Form 373 (Wholesale Exemption Certificate)[^1]

No Cost Deductions

Unlike Oregon's CAT, Delaware's GRT allows no deductions for cost of goods, labor, interest, discounts, delivery costs, or taxes paid[^1].

Filing Requirements

Filing Frequency

Filing frequency is assigned based on gross receipts during a look-back period. New businesses default to quarterly filing.

Filing Method

Mandatory electronic filing since January 1, 2021 via tax.delaware.gov[^1].

Penalties

Nexus

Delaware taxes gross receipts from business activity conducted within the state. Out-of-state shipments where the seller ships directly to customers outside Delaware are exempt. Interstate sales taken delivery in Delaware remain taxable[^1].

For businesses unsure about Delaware nexus, contact the Gross Receipts Department at (302) 577-8780 or grt@delaware.gov.

City/Local Tax Overlays

Delaware's major cities (Wilmington, Dover) do not impose separate city-level gross receipts taxes. The GRT is a state-level tax only. Wilmington has a city wage tax (1.25%) but no additional business gross receipts tax.

Calculation Process

Step 1: Determine Business Category

Identify which GRT category applies. If multiple activities, file separately for each.

Step 2: Apply Monthly Exclusion

Subtract the monthly exclusion for your category.

Step 3: Compute Tax

monthly_tax = rate × max(monthly_gross_receipts - monthly_exclusion, 0)

Step 4: File Monthly or Quarterly

Sum monthly calculations for quarterly filers.

Example: Delaware Retailer

Monthly gross receipts: $250,000
Category: Retailer
Rate: 0.7468%
Monthly exclusion: $100,000

Taxable receipts: $250,000 - $100,000 = $150,000
Monthly tax: $150,000 × 0.007468 = $1,120.20

Annual estimate: $1,120.20 × 12 = $13,442.40

Common Mistakes

1. Forgetting the monthly exclusion — Each category has an exclusion that significantly reduces tax for smaller businesses[^2]
2. Deducting expenses — GRT is on gross receipts with no deductions for COGS, labor, or any costs[^1]
3. Single return for multiple activities — Businesses with revenue from different categories must file separate returns for each[^1]
4. Confusing with sales tax — Delaware has no sales tax. GRT is paid by the business on its receipts, not collected from customers
5. Missing electronic filing requirement — All GRT returns must be filed electronically since 2021[^1]
6. Wrong exclusion amount — Exclusions vary dramatically by category ($10K for wholesalers vs. $1.25M for manufacturers)[^2]
7. Quarterly filers using monthly exclusion — Quarterly filers get quarterly exclusion amounts (3× monthly), not monthly
