Multiple business activities
If a sole proprietor performs both retail sales and professional services, separate GRT licenses and filings are required for each activity at the respective rate.
Online/remote sellers
If you sell tangible goods to Delaware customers from outside Delaware, you may be subject to GRT based on nexus rules. Physical presence in Delaware triggers GRT; economic nexus rules may also apply.
Interaction with income tax
GRT paid is a deductible business expense on federal Schedule C (and therefore reduces Delaware taxable income). It is NOT a pass-through tax to the customer (unlike sales tax), though some businesses choose to include it in pricing.
Record-keeping
Maintain monthly gross receipts records by business activity category. The Division of Revenue may audit and reclassify business activity if the registered category does not match actual operations.
DE-GRT-1.01
GRT is levied on the seller/provider, not the buyer/customer
DE-GRT-1.02
Tax base = total gross receipts minus monthly/quarterly exclusion
