Local income tax is a tax imposed by many localities and cities on businesses based on their income earned from local sources. This tax is in addition to federal and state income taxes, and the rules and regulations for local income tax can vary depending on the jurisdiction. As a result, local income tax return processing requires the expertise of a local tax CPA with experience and knowledge in this area.
DHJJ assists our clients in identifying and claiming tax deductions and credits that may be available to them, reducing their tax liability while abiding by local regulations. This is particularly important in local jurisdictions where tax rules and regulations may differ significantly from other regions.
