Dental Practice Tax and Accounting Records Checklist

Start with the practice entity and filing history

The form of business affects which federal return is generally filed. Identify whether the practice operated as a sole proprietorship, partnership, S corporation, C corporation, or more than one entity during the year.

Gather the prior federal and state returns, depreciation schedules, ownership records, formation and election documents, tax identification information, carryforward schedules, and correspondence about filing status. Note ownership, entity, accounting-method, address, payroll, or state changes instead of assuming the prior-year setup still applies.

Reconcile practice revenue to deposits and source reports

The books should identify the source of receipts and support the income reported on the return. For a dental practice, that may require comparing practice-management reports, patient collections, insurer or administrator remittances, merchant-processor activity, refunds, chargebacks, financing receipts, and other deposits with the bank activity and general ledger.

Do not treat a bank deposit total as a complete revenue analysis without identifying transfers, loans, owner contributions, refunds, timing differences, and receipts deposited into another account. Keep the underlying remittance, deposit, and adjustment reports used to explain the reconciliation.

Prepare support for expenses and bookkeeping balances

A payment record by itself may not establish the business purpose or tax treatment. Retain the invoice, receipt, agreement, or other source document that identifies what was purchased and how it relates to the practice.

• Year-end profit-and-loss statement, balance sheet, general ledger, trial balance, and chart of accounts
• Bank and credit-card statements with completed reconciliations
• Invoices, receipts, canceled checks, account statements, and electronic-payment support
• Lease, software, laboratory, supplies, insurance, professional-fee, education, travel, and other expense records
• Loan statements, year-end balances, interest information, and new financing agreements
• Prior-year closing entries and a list of unresolved, uncategorized, duplicate, or personal transactions

Keep payroll and workforce records by filing period

Employers generally have federal withholding, Social Security, Medicare, unemployment, deposit, filing, and year-end reporting responsibilities. Gather records for employees and dentist-owners on payroll rather than relying only on the final annual wage total.

• Payroll registers and payroll-provider reports
• Forms 941 or 944, Form 940, state payroll filings, and deposit confirmations
• Forms W-2 and W-3, corrections, and delivery or filing evidence
• Owner compensation, reimbursements, benefits, retirement contributions, and health-insurance records
• Employee and contractor classifications, agreements, payment totals, and applicable information returns
• Payroll notices, late filings, returned payments, or unresolved agency balances

Build an asset file for dental equipment and improvements

Business equipment and improvements may be recovered through depreciation or another treatment depending on the property, facts, elections, placed-in-service date, business use, and current law. Keep asset-level information so the preparer can determine the applicable treatment rather than working from one combined payment total.

• Vendor invoice and detailed description of each asset or project
• Purchase, delivery, installation, and placed-in-service dates
• Financing agreement, trade-in information, rebates, and separately stated costs
• Business-use information and location
• Prior depreciation schedules and Section 179 or other election information
• Records for equipment sold, traded, abandoned, converted, or removed from service
• Leasehold-improvement contracts, invoices, drawings, and completion dates

Separate owner activity from practice expenses

Track owner contributions, distributions, draws, loans, repayments, reimbursements, compensation, benefits, and personal expenses separately. The classification can affect the practice books, entity return, owner reporting, basis records, payroll, and year-end questions.

For a multi-owner practice, keep ownership percentages, capital activity, debt arrangements, guaranteed-payment information when relevant, and written agreements available. Legal interpretation and ownership disputes should be addressed with qualified counsel.

Collect estimated-tax, state, and notice records

Do not assume a tax or registration applies—or does not apply—based only on the practice label. Entity type, transactions, products, services, jurisdictions, and the complete facts must be reviewed under current law.

• Federal and state estimated-tax payments for the practice and owners, including confirmation numbers and dates
• Owner withholding from wages and other income
• Prior-year overpayments applied forward
• Florida corporate-income-tax or other state business filings when applicable
• Sales-tax registrations, returns, payments, notices, or audit correspondence when applicable to taxable activity
• Complete IRS and state notices with every page, enclosure, printed response date, and record of prior contact

Connect the practice records to each owner return

When an owner’s individual return is also in scope, gather the final Schedule K-1 or business schedule information, wage records, health-insurance and retirement items, estimated payments, state activity, outside income, and other facts needed for that separate filing.

Business and individual returns can be coordinated, but they remain separate services and filings. Confirm every entity, owner, return, state, and tax period included in the engagement.

Use the public form only to request a conversation

Do not upload or paste tax returns, Social Security numbers, employer identification numbers, payroll files, patient information, bank details, notices, or other sensitive records into a public contact form or ordinary email.

For the first call, provide only the practice entity, number of owners, service needed, tax periods and states, condition of the records, and any known deadline. If an engagement is accepted, use the secure document workflow provided during onboarding.
