Buy a Dental Practice in Washington: Receipts and Cash

Start with the activities the Washington buyer will operate

A practice can deposit money from several sources while showing one bank total. Dental services, separate product sales and financing can all reach the same account. They do not answer the same question about the business. A buyer needs to know which activity earned the money, when it arrived and what work must continue to support it.

Washington's dental tax rule places income from dental services under service and other activities B&O tax. It distinguishes goods sold apart from care from items supplied as part of care. It also addresses equipment purchases and qualifying exemptions. Actual facts control the result. (Source: Washington WAC 458-20-151; reviewed September 8, 2026.)

Describe the proposed operation in plain terms before building the budget. Will the incoming practice provide only care to its own patients? Does it also sell products apart from that care? Are there laboratory services or other activities that need separate review? The tax adviser needs those facts, not just the name of a revenue account.

This page helps organize that review. The national buying guide covers the broader acquisition process. Keep professional licensing, permitted ownership, space, payer arrangements and financing on their own review lists. A completed tax worksheet does not establish that the proposed practice may operate as planned.

Separate gross income from the cash left to the owner

Washington DOR describes B&O as a tax on gross receipts. Ordinary business expenses, including labor and materials, do not reduce that gross base. The applicable activity affects classification, and credits may be available. This guide supplies no rate or credit determination. (Source: Washington DOR: Business and occupation tax; reviewed September 8, 2026.)

Build two linked schedules. One explains the income and activity detail for the tax preparer. The other follows actual receipts and cash uses for the buyer. A payroll increase belongs in the operating forecast even when the income schedule stays unchanged. A financing deposit belongs in the cash record even when it did not arise from patient work.

Avoid treating the state tax base as an earnings measure. It does not tell you how much work the owner performed, what replacement labor will cost or how much debt the buyer will pay. The SDE and seller-net guide explains those separate measures. Name the measure beside every subtotal so another reviewer can follow it.

Request a file that connects activity, books and deposits

Ask for a defined period and preserve its start and end dates. Request the income detail, deposits and prior returns through the authorized review process. Record the accounting method and the settings used to prepare each report. A return shows what was filed; it is evidence to reconcile rather than proof that every entry was correct.

Use a question log for gaps. An entry should identify the amount, date, report and needed explanation. Leave the tax treatment unresolved until the adviser has enough evidence. Do not bury an unmatched amount in a miscellaneous account to make two totals agree.

For a broader reporting review, follow the production and collections guide. Here the extra decision is how the activity record supports Washington reporting and the buyer's operating cash plan. It is not a second collection-rate calculation or a recommendation to change patient care.

Worked example: explain a quarter of bank credits

This invented seller-quarter example uses cash receipts only to demonstrate reconciliation. It is not a filed return, an appraisal or a buyer forecast. Assume complete supporting records, no refunds or settlement timing differences, and no deductions or credits modeled. A tax preparer still must confirm the actual method and treatment before using a real schedule.

The seller has $268,000 of bank credits. Current-quarter care accounts for $218,000. Another $18,000 pays for the seller's own earlier care. Both relate to the seller's operation during the period being reviewed. The example makes no claim that a buyer purchases those receivables or will collect them after closing.

The receipt schedule contains $236,000 from care and $12,000 from separate sales, or $248,000. The other $20,000 consists of $1,200, $15,000 and $3,800. Together, $248,000 plus $20,000 equals the bank's $268,000. The collected-tax amount is invented; it does not quote or establish a Washington tax rate.

This bridge explains the inputs without calculating tax. In a real review, match the $248,000 to the applicable accounting method and adviser-supported reporting. Do not call every bank credit revenue. Also do not call every receipt from earlier work a repeatable source of next quarter's cash.

Test a cost change separately from an activity change

Assume the same invented quarter has $205,000 of operating cash costs. This includes the stated labor model and ordinary recurring bills. It excludes B&O and other taxes, acquisition debt service, capital purchases and owner draws. The $43,000 difference between $248,000 and $205,000 is therefore a limited subtotal. It is not take-home pay or free cash flow.

The second case has the same activity receipt inputs as the first. Higher costs reduce the cash subtotal by $9,000. They do not explain a lower gross-income figure. In the third case, care receipts fall to $216,000 while separate sales stay at $12,000. Total business receipts fall to $228,000. Each case changes only the assumption named in its row.

Before using either sensitivity, identify the cause. A missed deposit may shift timing. A reduced work schedule may reduce completed activity. A planned hire may change labor cost and capacity together. The simple table deliberately holds other inputs fixed so the arithmetic can be checked; it does not predict how a real practice responds.

Carry the remaining cash uses into the working-capital plan. Do not use the positive $43,000 subtotal to erase the need for taxes, debt payments or startup cash. The buyer's actual plan needs its own dates and supporting costs.

Review acquisition assets on a separate tax schedule

DOR's asset-purchase guidance distinguishes taxable tangible assets from other property and qualified exceptions. It states that a buyer may owe use tax if the seller fails to collect sales tax on taxable property. Do not assume that purchasing a whole practice makes every included item exempt. (Source: Washington DOR: Buying the assets of a business; reviewed September 8, 2026.)

Give the adviser an itemized schedule and intended use. Include the supporting purchase records, ownership facts and any proposed exemption evidence. Ask who will collect or pay each amount and where it appears in the closing cash plan. Keep unknown tax amounts open rather than inserting a convenient estimate from another purchase.

The purchase-price allocation guide covers the separate federal reporting question. An agreed total does not resolve every state classification. Match both reviews to the same final asset list. A changed item or use needs to reach both advisers before the documents become final.

Resolve predecessor tax exposure before relying on the closing check

Washington's successor-tax statute addresses withholding for tax due, proof of payment or no tax due, and a notice-based route with specific conditions. Those are distinct steps. A request or submission alone is not a receipt proving all tax has been paid. Have counsel apply the statute to the actual transaction. (Source: Washington RCW 82.32.140; reviewed September 8, 2026.)

List each requested document, its exact purpose and its status. Record who will obtain it and what remains unresolved. Do not describe a general status letter as broader protection than its content provides. Keep the seller's payment obligation, buyer exposure and any contractual recourse separate in the review.

The LOI guide helps frame the process before final terms. The parties' advisers should identify which findings affect cash handling and which affect readiness to close. This page gives no universal holdback percentage, agency response promise or closing deadline.

Control identifying disclosure, staff access and patient records

Begin outreach with a seller-blind description. Omit the owner, practice name, exact location, financial figures and details that reveal the practice, staff or patients. Complete the NDA before identifying buyer disclosure. Then share relevant records through controlled access, with the seller's authorized scope and the reviewer's role clear.

Bring staff into the process when their participation is needed and when applicable duties require communication. Explain their assigned work and confirmed facts. Do not wait for an arbitrary deal milestone if it prevents required tasks. Avoid promises about jobs, pay or buyer plans that have not been established.

Washington's patient-disclosure statute includes a successor-provider pathway and a separate audit pathway with written safeguards. It also excludes specified sensitive information from those provisions. An NDA does not independently establish patient-access authority; use legal and privacy review to determine the permitted purpose, scope and controls. (Source: Washington RCW 70.02.200; reviewed September 8, 2026.)

The dental record rule requires accessible records for at least six years from last treatment. It separately addresses responses to written patient requests and compliance with privacy rules. Preserve access through the transition; the minimum is not blanket permission to destroy files. (Source: Washington WAC 246-817-310; reviewed September 8, 2026.)

Use the patient-records transfer guide for the custody workstream. Financial diligence should not disrupt patient requests. Clinical decisions remain with the responsible clinicians under the patient's circumstances.

Common mistakes in a Washington buyer review

One error is treating lower profit as proof of a lower gross tax base. Another is accepting every bank credit as earned income. A third is assuming a supply account tells you whether goods were used in care or sold separately. Correct these with transaction evidence and a clear accounting method.

Also watch for double counting. A loan can fund the bank account without improving operating receipts. Collected tax owed onward cannot also be treated as owner spending money. Receipts from the seller's earlier work cannot automatically become the buyer's opening cash source.

Do not annualize one quarter merely by multiplying by four. Review the available history and explain the drivers before projecting a year. A clean reconciliation makes the model easier to examine; it does not guarantee continued receipts, financing or a suitable acquisition price.

Summary: carry the right number into each decision

First identify the activities. Then connect their records to the books and the bank. Keep the gross-income review separate from the operating cash forecast and the asset-purchase tax schedule. Obtain the transaction-specific tax and legal conclusions before relying on closing cash or a claimed clearance.

Use unresolved items to direct the next request. A buyer can proceed with clearer evidence when the income source, cost plan, transferred assets and disclosure controls are visible. The decision should rest on the actual Washington practice and the operation the buyer intends to run.
