How Much Should a Small Business Set Aside for Taxes in New Jersey?

Running a small business in New Jersey comes with plenty of rewards — and plenty of tax obligations. One of the most common questions Bergen County business owners ask us is: how much of my revenue should I be setting aside for taxes? The honest answer is that it depends on your business structure, income level, and deductions, but there are solid benchmarks you can start with today.

At Tsamutalis & Company, we’ve been advising New Jersey small businesses on tax strategy since 1992. Here’s what you need to know.

The Federal Tax Baseline: Start with 25–30%

Most small business owners should plan to set aside 25–30% of their net profit for federal income taxes. This figure covers:

  • Federal income tax (10%–37% depending on your bracket)
  • Self-employment tax (15.3% on the first $176,100 of net earnings in 2026, 2.9% above that)

If your business is profitable and growing, lean toward the higher end. If you’re in the early stages with significant deductions and startup costs, you may land closer to 25%.

Don’t Forget New Jersey State Taxes

New Jersey has its own business tax obligations on top of federal requirements. Depending on your structure:

Sole Proprietors & Single-Member LLCs

Your NJ income from the business flows through to your personal NJ-1040. New Jersey’s income tax rates run from 1.4% up to 10.75% for high earners. For most small business owners in Bergen County, you’ll fall in the 5.525%–8.97% range.

S-Corporations

S-Corps in New Jersey file a CBT-100S and are subject to the NJ Corporate Business Tax minimum fee (based on New Jersey gross receipts), even if the business shows a loss. Shareholders then pay personal income tax on their allocated share.

C-Corporations

C-Corps pay the NJ Corporate Business Tax at 9% (or higher for very large companies). This is separate from any federal corporate tax liability.

The Practical Rule of Thumb for NJ Small Businesses

For most Bergen County small business owners — especially sole proprietors, single-member LLCs, and S-Corp shareholders — we recommend setting aside 30–35% of net profit. Here’s why the number goes higher in NJ:

  • NJ state income tax adds 5%–9% on top of federal
  • Self-employment tax is 15.3% on earned income
  • NJ has no standard deduction for sole proprietors — your business deductions are your only relief

So if your NJ small business nets $120,000 this year, you should have $36,000–$42,000 set aside for taxes.

Quarterly Estimated Tax Payments in New Jersey

One critical mistake small business owners make is waiting until April to pay their tax bill. The IRS and the State of New Jersey both require quarterly estimated tax payments if you expect to owe more than $1,000 (federal) or $400 (NJ) in taxes for the year.

New Jersey quarterly due dates align closely with federal deadlines:

  • Q1: April 15
  • Q2: June 15
  • Q3: September 15
  • Q4: January 15 (of the following year)

Missing these deadlines can result in underpayment penalties from both the IRS and New Jersey Division of Taxation. A CPA can calculate your safe harbor payment amounts to avoid this entirely.

Deductions That Reduce Your Taxable NJ Business Income

The good news: you’re not taxed on gross revenue — you’re taxed on net profit after deductions. Common deductions for Bergen County small businesses include:

  • Business use of home (home office deduction)
  • Mileage and vehicle expenses for business use
  • Health insurance premiums for self-employed owners
  • Retirement contributions (SEP-IRA, Solo 401(k))
  • Business equipment and technology (Section 179 expensing)
  • Salaries and wages paid to employees
  • Professional services, including accounting and legal fees

Properly documenting and capturing all available deductions is one of the most impactful things a Bergen County CPA can do for your tax bill.
