New Jersey's CBT Surcharge Catches
Most Businesses Off Guard

The Corporation Business Tax (CBT) surcharge is an additional 2.5% tax (making the top rate 11.5%) on C-Corporations with an allocated taxable net income over $1 million in New Jersey. It does not apply to S-Corporations or pass-through entities, making entity selection a critical strategy.

NJ BAIT allows pass-through entities (like LLCs and Partnerships) to elect to pay state income tax at the entity level rather than the personal level. This workaround helps business owners bypass the federal $10,000 SALT deduction cap, potentially saving thousands in federal taxes.

New Jersey employers must withhold and remit state income tax, as well as contributions for Unemployment Insurance (UI), Temporary Disability Insurance (TDI), and Family Leave Insurance (FLI). Navigating these specific deductions correctly is essential to avoid penalties.

While the NJ-PA reciprocity agreement is currently still in effect, any changes or ending of reciprocity agreements with neighboring states like NY or PA mean employers must carefully track where employees live versus work to ensure correct state income tax withholding.

You should consider a fractional Controller or CFO when you hit $2M+ in revenue, plan to expand across state lines (triggering nexus issues), or need strategic help navigating NJ's high-tax environment, such as optimizing for the BAIT election or managing CBT exposure.
