How to Verify Your Dental Practice's Numbers Before Tax Season
A CPA does not audit your practice. A CPA prepares a tax return from the numbers you provide. If your collections, deposits, and adjustments do not actually reconcile, your CPA produces a clean-looking return built on numbers that were never verified.
The Misconception About What a CPA Does
Many dental practice owners assume that handing their financials to a CPA each year is a form of verification, that the accountant will catch errors, surface fraud, and confirm the numbers are right. This is a misunderstanding of what a standard tax engagement involves.
A CPA preparing a dental practice's tax return works from the financial records the practice provides. Their job is to apply tax law correctly to those records, optimize the practice's tax position, and file an accurate return based on the inputs. Their job is not, under a standard engagement, to perform a forensic reconciliation of the practice's collections against its bank deposits, to verify that every insurance payment posted actually arrived, or to detect whether an employee has been diverting funds.
If the numbers the practice provides are wrong, the CPA produces a return that is wrong in the same way, and it looks just as clean as a correct one. The CPA is not failing at their job. Verification of the underlying numbers was never part of the engagement unless the practice specifically asked and paid for it.
This means the responsibility for ensuring the numbers are actually right sits with the practice, before the financials ever reach the accountant. Tax season is the natural deadline that forces this question, which makes the weeks before it the right time to verify.
Why Pre-Tax Verification Matters
Verifying the practice's numbers before tax season serves several purposes beyond a cleaner return.
It catches errors while they are still fixable. Reconciliation discrepancies, misposted payments, and accounting mistakes are far easier to correct before the return is filed than after.
It surfaces revenue leakage. The verification process reveals unbilled encounters, payer underpayments, and reconciliation gaps that the practice can still act on, sometimes recovering revenue from the prior year.
It can surface embezzlement. A practice that has been the victim of internal theft often discovers it during a thorough financial verification, and discovering it before filing avoids the additional complication of an inaccurate return based on the manipulated numbers.
It produces a return that reflects reality. A tax return built on verified numbers is one the practice can defend, and one that accurately represents the practice's true financial position for purposes of lending, valuation, or a future sale.
It reduces audit risk. Returns with internal inconsistencies, especially mismatches between reported income and the income reported to the IRS by third parties, draw scrutiny. Verified numbers reduce that exposure.
The Verification Checklist
Here is what a practice should verify before sending financials to its CPA.
Reconcile Collections to Bank Deposits
For the full tax year, total collections recorded in the practice management system should reconcile to total deposits in the practice's bank accounts, accounting for normal timing differences at year-end. A material gap means money recorded as collected did not reach the bank, which can indicate posting errors, merchant processing deductions, or diversion. This is the single most important verification.
Reconcile Insurance Payments to Remittances
The insurance payments posted in the practice management system should match what the payers' remittance advices say was sent. Insurance money the payers report sending that does not appear in the practice management system, or in the bank, is a gap that needs explanation.
Review the 1099-K Against Reported Income
Merchant processors report total card payment volume to the IRS on Form 1099-K, and that figure includes any surcharges the practice added. If the practice's reported income does not reconcile with the 1099-K, the mismatch can look like underreported income to the IRS. This is an increasingly watched discrepancy, and it should be reconciled before filing.
Examine Adjustments and Write-offs
Total adjustments and write-offs for the year should be consistent with the practice's payer mix and historical patterns. Unusual increases, or adjustments concentrated around specific users or patients, warrant a closer look before the year's numbers are finalized. This review sometimes surfaces both billing problems and fraud.
Review Credit Balances
Credit balances owed back to patients and payers should be identified and quantified. A large aggregate credit balance is both a liability the practice carries and a sign that the refund process has broken down. It also matters for an accurate financial picture.
Confirm AR Is Realistically Valued
Accounts receivable that will never be collected is not really an asset. Reviewing the AR by age and assessing realistic collectibility gives the practice and the CPA an accurate picture, rather than carrying stale, uncollectible balances as if they were money.
Verify Refunds Trace to Overpayments
Every refund issued during the year should trace to a specific overpayment, going back to the patient or payer that made the original payment. Refunds to accounts that do not match original payments are the strongest single indicator of embezzlement, and tax-season verification is a natural time to run this check.
How to Actually Do the Verification
Practices have a few options for the verification itself.
The practice can do it internally, provided the person doing the verification is not the same person who handles the practice's money day to day. Separation matters here, the verification has no value if the person being checked is doing the checking.
The practice can engage its CPA for an expanded engagement that includes reconciliation and verification, beyond standard tax preparation. This costs more than a standard engagement but delivers actual verification. A practice that wants this should ask specifically and confirm it is in scope.
The practice can use continuous reconciliation throughout the year, so that verification is not a scramble in the weeks before tax season but an ongoing state. A practice that reconciles continuously arrives at tax season with numbers that are already verified, and the CPA receives clean, trustworthy inputs.
The continuous approach is the strongest, because tax-season verification done once a year still leaves eleven months during which problems can develop and compound undetected. But any verification is far better than none, and a practice that has never verified its numbers should start with a thorough pre-tax review this year.
Frequently Asked Questions
Does my CPA verify my dental practice's numbers?
Generally no. Under a standard tax engagement, a CPA prepares the return from the financial records the practice provides and applies tax law correctly. They do not, by default, reconcile collections against bank deposits or perform forensic verification of the underlying numbers. Verification is the practice's responsibility unless the CPA is specifically engaged and paid for it.
What should I check before sending financials to my accountant?
Reconcile total collections to total bank deposits, reconcile insurance payments to payer remittances, check the 1099-K against reported income, review adjustments and write-offs for unusual patterns, quantify credit balances, assess whether AR is realistically valued, and verify that refunds trace to actual overpayments.
Why does my 1099-K matter for taxes?
Merchant processors report total card payment volume to the IRS on Form 1099-K, including any surcharges. If your practice's reported income does not reconcile with the 1099-K figure, the mismatch can appear to the IRS as underreported income. Reconciling the two before filing avoids that red flag.
Can verifying my numbers before tax season catch embezzlement?
Yes. A thorough financial verification often surfaces embezzlement, particularly through reconciliation gaps between recorded collections and actual deposits, and through refunds that do not trace to legitimate overpayments. Discovering it before filing also avoids building a tax return on manipulated numbers.
When should I verify my dental practice's numbers?
Ideally numbers are verified continuously throughout the year, so the practice is always in a verified state. At minimum, a thorough verification should happen in the weeks before financials go to the CPA for tax preparation, while errors are still fixable and prior-year revenue may still be recoverable.
