Delaware Gross Receipts Tax: Rates by License Category, the $100,000 Monthly Exclusion, and How to File

Delaware has no state sales tax. Instead, the state collects a gross receipts tax (GRT) from businesses operating under a Delaware business license. This is a critical distinction: you pay GRT on your total revenue, not on what customers pay you. The rate depends on your business category, and understanding the thresholds and exclusions can save you significant time and money at filing time.

What Is Delaware Gross Receipts Tax?

Gross receipts tax is a state-level tax imposed on gross revenues generated by businesses operating in Delaware. Unlike a sales tax (which Delaware does not have), GRT is owed by the seller, not collected from the customer. You pay the tax on the gross amount of money you receive from sales, services, or transactions, with limited deductions allowed.

The tax is administered by the Delaware Division of Revenue. To legally operate a business in Delaware, you must obtain a Delaware business license, and once licensed, you become obligated to pay GRT based on your license category.

One important clarification: GRT is not a sales tax, and Delaware issues no seller's permits. You pay the tax directly to the Division of Revenue on your licensed business receipts.

GRT Rates by License Category

Delaware imposes different GRT rates depending on the type of business you operate. These rates are set by statute and apply to all businesses in that category. Here are the primary rates:

License Category	GRT Rate
General Services and Wholesale	0.3983%
Retail (General)	0.7468%
Restaurants, Caterers, Takeout, and Contractors	0.6472%
Food Processors and Bakeries	0.1991%
Manufacturers	0.126%
Grocery Supermarkets	0.3267%

If your business operates in more than one category, or you are unsure whether you qualify for the wholesaler rate (0.3983%) rather than the retail rate (0.7468%), confirm your classification with the Division of Revenue or a tax professional.

Petroleum wholesale operations incur an additional 0.2489% on top of the wholesaler base rate. Auto manufacturers and clean-energy-device manufacturers operate under a reduced rate of 0.0945%.

The $100,000 Monthly Exclusion

Delaware law allows a monthly exclusion on gross receipts before the GRT rate is applied. For most monthly-filing businesses, the exclusion is $100,000 per month. This means only receipts above $100,000 are subject to the tax.

How the Exclusion Works

If you are a general services business filing monthly and your gross receipts in a month are $105,000, your taxable base is $5,000. At the 0.3983% rate, you would owe $19.92 in GRT for that month (the business license fee is separate).

Here is the exclusion structure by filing frequency:

• Monthly filers: $100,000 monthly exclusion
• Quarterly filers: $300,000 quarterly exclusion (newly formed businesses and those with lower revenue typically file quarterly)
• Manufacturers: $1,250,000 monthly exclusion

The exclusion is calculated per enterprise. If you control multiple related business entities, the Division of Revenue treats them as one enterprise for exclusion purposes, meaning you get one $100,000 (or applicable) exclusion across all of them combined, not per entity.

If your receipts fall below the exclusion threshold, you still owe no GRT for that period. You must, however, still file your return; the annual business license fee also still applies.

When You File: Monthly vs. Quarterly

New Businesses and Quarterly Filers

When you first obtain a Delaware business license, you are assigned to quarterly filing status. Quarterly returns are due on the last day of the month after each quarter ends:

• Q1 (January through March): Due April 30
• Q2 (April through June): Due July 31
• Q3 (July through September): Due October 31
• Q4 (October through December): Due January 31

Monthly Filers

You are required to switch to monthly filing once your gross receipts exceed a threshold set by Delaware statute. The statutory threshold is $1,500,000 in lookback receipts, and 30 Del. C. 515 provides for annual adjustment. Check with the Division of Revenue for the current figure before relying on this number.

Monthly returns are due on the 20th of the following month. For example, January receipts are reported by February 20.

Online Filing Is Mandatory

Delaware has required all businesses to file returns online since January 1, 2021. File through the Division of Revenue's online portal at https://revenue.delaware.gov/. The portal will guide you through the filing process and allow you to pay your GRT and license fees electronically.

What Receipts Are Subject to GRT

Gross receipts include all money your business receives from its operations, with very limited exceptions:

• Revenue from sales of tangible goods
• Revenue from services rendered
• Rental income from business property
• All other consideration received in exchange for business activity

You do not get to deduct the cost of goods, materials, labor, interest paid, delivery costs, or taxes paid. The only deduction is the monthly or quarterly exclusion. This is why the tax is called a "gross" receipts tax, not a net income tax.

Important Exception: Out-of-State Sales

If you ship goods directly to a customer outside Delaware, and the customer takes possession of those goods outside Delaware, that sale is not subject to Delaware GRT. Keep detailed shipping records to document where the customer took possession. If the customer takes possession in Delaware, the retail GRT rate applies to that sale.

A wholesaler whose out-of-state customer takes possession of the goods in Delaware needs a Form 373 Wholesale Exemption Certificate completed before or at the time of the sale for that sale to be exempt. Work with the Division of Revenue to ensure you are properly documenting these transactions.

Late Payment Penalties and Interest

If you file your return late or pay your GRT late, Delaware imposes significant penalties:

• 5% penalty for each month (or partial month) the tax is late
• 0.5% monthly interest on the unpaid tax
• 1% additional monthly penalty for failure to pay, up to a maximum of 25% of the tax owed

These penalties compound quickly. A $1,000 tax bill that is 30 days late incurs at least $50 in penalty (5%) plus about $5 in interest (0.5%). After three months, the penalties grow substantially. File and pay on time to avoid these costs.

The Annual Business License Fee

The GRT is separate from your Delaware business license fee. Most business categories pay an annual license fee of $75 (prorated by full calendar months if you obtain your license mid-year). General retailers pay $90 annually, which includes a $15 retail crime fee. Each additional location costs $25 annually.

Licenses run for one year and expire on December 31. You can renew for three years at three times the annual fee if you prefer. These fees are paid when you obtain or renew your license through Delaware One Stop.

Step-by-Step: How to File Your GRT Return

1. Gather your records. Compile all gross receipts for the filing period (month or quarter). If you have discrepancies, resolve them now.
2. Calculate taxable receipts. Subtract the applicable exclusion ($100,000 for most monthly filers, $300,000 for quarterly filers) from your total gross receipts. If the result is zero or negative, your taxable base is zero and you owe no tax for that period.
3. Apply your rate. Multiply your taxable receipts by your business category's GRT rate (e.g., 0.003983 for services). Round to the nearest cent.
4. Log into the Division of Revenue portal. Visit https://revenue.delaware.gov/ and log in with your Delaware business license number and credentials.
5. Select the return type. Choose monthly or quarterly return based on your filing status.
6. Enter your receipts. Input your gross receipts and calculated GRT liability.
7. Review and submit. Double-check all figures before submitting. The system will calculate your total liability.
8. Pay electronically. The portal accepts payment via bank account debit, credit card, or other methods. Pay by the deadline to avoid penalties.

Common Filing Mistakes to Avoid

• Forgetting to subtract the exclusion. Many businesses miscalculate because they apply the rate to all receipts, not just those above the exclusion. This overstates liability.
• Including federal income tax or payroll taxes in gross receipts. These are not part of gross receipts and should not be included in your filing.
• Misclassifying your business category. Claiming a wholesale rate when your business is primarily retail, or vice versa, can trigger a Division of Revenue audit. Classify accurately.
• Filing late. Missing the deadline by even one day triggers penalties. Calendar your filing dates well in advance.
• Failing to file when receipts are below the exclusion. Even if you owe zero tax, you must still file your return. Failure to file carries its own penalties.
