IRS examination-selection criteria and scoring weights are not public, so no return pattern supplies a published prediction of selection. High deductions, home-office claims, rounded entries, information-return differences, meals, and vehicle costs should instead be supported by complete books and contemporaneous records.
How Do I Support High Schedule C Deductions?
The IRS does not publish a deduction percentage that determines selection. Claim only supported deductions and retain the records that establish each amount, timing, payee, and business purpose.
How Do I Support a Home Office Deduction?
A qualifying home office is a legitimate deduction when applicable exclusive-and-regular-use rules are met. Keep measurements, photos, and records of business use rather than treating any deduction as a selection predictor.
Why Do Round Numbers on My Tax Return Look Suspicious to the IRS?
A return full of round numbers suggests estimation. Track actual expenses and report real amounts.
What Happens If I Have Unreported Income the IRS Already Knows About?
The IRS receives information returns. An unresolved difference can lead to matching correspondence or review, but it does not automatically produce a notice; reconcile the form to the return and retain supporting records.
How Should I Substantiate Large Meal and Vehicle Deductions?
Both require substantiation. For a client or business-associate meal, record the amount, date, place, business purpose, and attendees. A qualifying meal during the taxpayer's own overnight business travel does not require inventing an attendee; retain the travel dates, destination, business purpose, and receipt. For vehicles, keep a contemporaneous mileage log or actual-expense records.
How Should I Prepare Records If the IRS Inquires?
Keep organized source records, reconcile accounts monthly, and preserve support for every reported amount. A CPA can review a return under a separately accepted written scope; no review predicts or controls IRS selection.
Key Takeaway
The best preparation for a possible inquiry or examination is a return backed by organized records. Substantiate deductions, reconcile every information return, and report actual amounts rather than estimates. No pre-filing review predicts or controls IRS selection.

Frequently Asked Questions
Does a Schedule C deduction ratio determine IRS selection?
No published Schedule C deduction percentage or Discriminant Inventory Function System (DIF) selection threshold determines whether the IRS will select a return. The selection formula is non-public; retain support for every deduction rather than avoiding a legitimate claim because of an assumed ratio.
What records support a home office deduction?
A home office can be deductible when applicable exclusive-and-regular-use rules are met. The simplified method ($5 per square foot, up to 300 square feet) can reduce calculation complexity, but either method requires records supporting business use, including measurements and applicable expenses.
Is there a predictable IRS examination timeline for a NJ small business?
No. The IRS does not publish a reliable outcome or resolution timeline for an individual matter. Preserve deadlines on any actual notice, provide only requested records, and obtain independently scoped representation if an examination opens.
What should I do if I realize I made an error on a filed return?
File an amended return (Form 1040-X for federal, NJ-1040X for NJ) as soon as you discover the error. Voluntary correction before the IRS contacts you can reduce or eliminate accuracy penalties. If the error resulted in underpayment, interest will accrue from the original due date, but the penalty exposure is generally much lower when you self-correct.
Ready to File With Confidence?
Tax rules change frequently. Use the contact form to request a written scope; submitting it does not promise a call, engagement, or outcome. Greg Monaco is a NJ-licensed CPA and the firm's sole practitioner.
