How New Jersey Reconstructs Sales and Why You Need an Attorney From the Beginning

You receive a letter from the New Jersey Division of Taxation saying your business is being audited. The auditor asks for sales records, purchase invoices, bank statements, and other financial documents going back several years.

There is just one problem. You do not have everything.

Maybe your point-of-sale system was replaced. Maybe your former accountant has records you cannot locate. Perhaps you kept daily sales totals but not every individual receipt.

Can New Jersey simply estimate how much your business sold and charge you sales tax based on those estimates?

Yes. When business records are inadequate, the New Jersey Division of Taxation can reconstruct sales using information such as vendor purchases, bank deposits, and estimated selling prices.

The result can be a tax assessment that is far higher than what your business actually owes.

That is why hiring an experienced New Jersey tax audit attorney at the beginning of an audit, rather than after receiving a large assessment, can make an enormous difference.

What Does It Mean When New Jersey Reconstructs Your Sales?

When the Division of Taxation audits a business, it generally starts by reviewing the business’s books and records.

These may include sales receipts, daily sales reports, purchase invoices, bank statements, cash register records, and sales tax returns.

If the auditor determines that those records are unreliable or incomplete, the State may use an indirect audit method.

Instead of relying on your reported sales, the auditor attempts to calculate what your business should have sold.

For example, the auditor may determine how much merchandise your business purchased, estimate how much you sold it for, and use that calculation to estimate your revenue.

The problem is that estimated sales are not necessarily actual sales.

An estimate based on incorrect assumptions can create a substantial tax liability.

How Does New Jersey Estimate Sales When Records Are Missing?

1. Purchase Markup or Mark-On Analysis

This is particularly common in restaurants, convenience stores, liquor stores, and other retail businesses.

The auditor examines what your business purchased and estimates the sales those purchases should have generated.

For example, suppose a restaurant purchased $200,000 in food and beverages during a year. The auditor determines that those purchases should have generated $600,000 in sales.

But the restaurant reported only $450,000.

The auditor may treat the $150,000 difference as unreported sales, subject to appropriate adjustments.

What if the auditor failed to account for food waste, employee meals, discounts, complimentary items, spoilage, or actual portion sizes?

The estimated sales could be significantly overstated.

2. Bank Deposit Analysis

The State may examine deposits into the business’s bank accounts and compare them with reported revenue.

But not every bank deposit is a sale.

Deposits may include owner contributions, loans, transfers between accounts, refunds, and other amounts that do not represent taxable sales.

If those amounts are not properly explained and documented, the auditor may incorrectly include them in the calculation.

3. Sampling and Projecting Errors Over Several Years

An auditor may examine a sample period and use the results to estimate the tax liability over a longer audit period.

Consider a restaurant with unusually high holiday sales during the selected sample period.

If the auditor uses that period without appropriate adjustments for seasonal changes, the results may exaggerate sales for the remainder of the year.

When the estimated difference is projected over multiple years, even a relatively small error can become a very large assessment.

A Real Example: Why Business Records Matter

At Tomes Law Firm, we have represented New Jersey restaurant owners facing sales tax audits with very different results.

One restaurant owner maintained detailed records, including information supporting the sales reported through the restaurant’s point-of-sale system.

Because the records could be used to verify actual sales, the audit resulted in less than $5,000 in exposure.

Another restaurant owner did not maintain the same level of documentation. The business lacked a reliable point-of-sale system, and there were problems with the records.

The Division used third-party purchase information and a markup analysis to reconstruct sales.

The result was a proposed tax liability in the six figures.

The difference illustrates an important lesson.

When you cannot prove what your business actually sold, you may find yourself defending against what the State believes you should have sold.

Even when records are missing, however, an assessment should not simply be accepted without examining the auditor’s methods and assumptions.

What Have New Jersey Courts Said About Missing Sales Records?

Two New Jersey Tax Court decisions illustrate why the adequacy of a business’s records can determine the outcome of an audit.

Saulwil: Missing Some Records Does Not Automatically Justify Estimated Sales

In Saulwil, Inc. v. Director, Division of Taxation, decided in 2020, the Division reconstructed a restaurant’s sales using a markup analysis.

The State claimed the restaurant lacked adequate records.

The resulting assessments involved hundreds of thousands of dollars in additional sales tax and individual income tax, including penalties and interest.

However, the Tax Court determined that the restaurant’s records were sufficiently reliable, despite certain missing documents and discrepancies.

The court rejected the State’s decision to use a markup analysis and reversed the related assessments, except for tax attributable to smaller discrepancies acknowledged by the taxpayer.

The important lesson is that imperfect records are not necessarily inadequate records.

The Division must have a reasonable basis for rejecting the business’s actual records and reconstructing sales.

Secaucus News: Missing Records Can Make It Extremely Difficult to Fight an Assessment

A more recent case demonstrates the other side of the problem.

In Secaucus News, Inc. v. Director, Division of Taxation, decided May 29, 2026, a New Jersey convenience store challenged an assessment arising from a sales tax audit and other tax examinations.

The business had not maintained or produced significant records requested by the auditor, including sales journals, register tapes, financial statements, and other supporting documents.

The Division issued an assessment totaling approximately $126,000, including penalties and interest.

The business attempted to challenge the assessment using reconstructed financial information.

However, the Tax Court found that the records were inadequate and that the business had not produced sufficient reliable evidence to overcome the State’s assessment.

The court granted summary judgment in favor of the Division.

The lesson is clear: Once the State determines that your records are inadequate, simply claiming the assessment is wrong is not enough. You need evidence to prove it.

These two cases demonstrate why experienced representation at the beginning of an audit can be so important.

An attorney can evaluate whether the State has a proper basis to reconstruct sales and whether the available records can support the amounts originally reported.

A Sales Tax Audit Can Create Other Tax Problems

Many New Jersey business owners assume a sales tax audit concerns only sales tax.

That can be a costly misunderstanding.

If the Division concludes that a business failed to report substantial sales, those findings may also lead to questions about:

• Whether the business understated income on its corporation business tax returns.
• Whether business owners received additional income that was never reported.
• Whether other business tax returns contain incorrect information.
• Whether additional penalties and interest should be assessed.

In Saulwil, the State’s reconstructed sales resulted in additional individual income tax assessments against the restaurant’s shareholders, as well as the business’s sales tax assessment.

Although those assessments were largely reversed, the case demonstrates how one disputed sales calculation can affect multiple taxpayers and tax liabilities.

An attorney needs to evaluate the entire tax exposure, not simply the sales tax number on the auditor’s worksheet.

Why You Should Hire a New Jersey Tax Audit Attorney Before the Audit Begins

Many business owners believe they can handle an audit themselves and hire an attorney only if something goes wrong.

Unfortunately, by that point, important decisions may already have been made.

We Review Your Records Before the Auditor Does

Before responding to extensive document requests, we want to understand what records exist, what records are missing, and whether the available information supports the returns that were filed.

Sometimes missing information can be obtained from banks, vendors, payment processors, accountants, or older accounting systems.

Finding that information early may prevent the State from relying on estimates that do not accurately reflect the business.

We Examine Whether the Auditor Can Justify Reconstructing Sales

Missing one document does not automatically make all your records inadequate.

As the Saulwil case demonstrates, records do not have to be perfect to be reliable.

Before accepting a reconstructed sales calculation, we examine whether the Division had a proper basis to reject the business’s actual records.

We Protect You Before You Agree to the Auditor’s Assumptions

This is one of the most important reasons to obtain representation early.

During an audit, a business owner may be asked to agree to a sample period, provide explanations about missing records, or discuss the auditor’s proposed calculation method.

A business owner may also be asked to sign documents extending the period in which the State can assess additional tax.

These decisions can have significant consequences.

For example, an auditor may select a period when sales were unusually high and use that period to estimate sales for several years.

Without understanding the consequences, a business owner may accept assumptions that produce an inflated tax assessment.

An attorney can review those requests, evaluate the proposed methodology, and raise objections before the calculations become the foundation of the assessment.

You should understand what you are agreeing to before signing anything or accepting the auditor’s calculations.

We Challenge Incorrect Calculations Before They Become Large Assessments

A markup calculation depends on assumptions about the business.

Those assumptions may involve selling prices, portion sizes, inventory, waste, discounts, or the percentage of taxable sales.

An attorney experienced in New Jersey sales tax audits can work with the business and its financial professionals to examine those assumptions and determine whether the calculation is reasonable.

The time to identify those problems is during the audit, not after the assessment has been issued.

We Handle Communications With the Auditor

A New Jersey tax audit can continue for months.

During that time, the auditor may request additional documents, question discrepancies, and seek explanations from the business owner.

Trying to manage those requests while operating a business can become overwhelming.

Our role is to manage the audit process, organize responses, address the auditor’s questions, and protect our client’s interests.

We want our clients concentrating on running their businesses, not spending their days trying to figure out what to send the Division of Taxation.

What If New Jersey Has Already Estimated Your Sales?

If you have already received a proposed assessment based on reconstructed sales, you may still have options.

Depending on the stage of the case, those options may include reviewing the auditor’s workpapers, submitting additional records, challenging the methodology, seeking administrative review, or pursuing an appeal.

However, waiting can limit opportunities to resolve problems early.

There are also strict deadlines for protesting or appealing tax assessments.

The fact that the auditor used an estimate does not automatically make the assessment correct.

But as Secaucus News demonstrates, you need credible evidence to show why the estimate is wrong.

What Does the New Jersey Division of Taxation Say About Audit Procedures?

The New Jersey Division of Taxation publishes a Manual of Audit Procedures that describes many of the techniques and procedures used by its auditors.

This includes guidance addressing business records, audit examinations, and various methods of determining tax liability.

New Jersey Manual of Audit Procedures (official Division of Taxation resource)

The manual provides general guidance for auditors. It does not replace the applicable tax laws or give taxpayers an independent legal basis to challenge an assessment.

Understanding how an audit is conducted can be helpful, but it is not a substitute for having an experienced representative evaluate your particular circumstances.

Frequently Asked Questions

Can New Jersey estimate my sales if I do not have receipts?

Yes. If the Division determines that your records are inadequate, it may use available information to estimate sales and determine tax liability.

Can I challenge the auditor’s markup calculation?

Yes. A reconstructed sales calculation may be challenged based on the adequacy of the records, the assumptions used, the available evidence, and whether the audit method was reasonable.

What if my point-of-sale system was replaced?

A replaced or unavailable POS system can create recordkeeping problems. Other records may help establish actual sales, although the business must still meet applicable recordkeeping requirements.

Can a sales tax audit create personal liability for the business owner?

Potentially. Depending on the circumstances, owners or other responsible persons may face personal liability for certain unpaid taxes. Additional alleged business income can also raise individual income tax issues.

Does New Jersey have to accept my accountant’s sales figures?

Not automatically. The Division may request source documents supporting the figures reported on your returns.

Should I hire an attorney before speaking with the auditor?

We recommend obtaining legal advice as soon as you receive the audit notice, particularly if your records are missing or incomplete. Early representation allows an attorney to evaluate your records, communicate with the auditor, and address potential problems before the audit progresses.
