Seasonality and cash flow: underwriting a tax practice's working capital

Why can a profitable tax practice need additional cash?

The practice may pay staff, software, rent, insurance, and purchase debt before collecting its largest fees. Annual profitability describes the total result; liquidity depends on the order and timing of receipts and obligations. A buyer should identify the cash needed to reach the next collection period while continuing acquired services.

Tax practice working capital should follow the actual engagement calendar. Separate individual returns, business returns, extensions, notices, monthly bookkeeping, and advisory work. Determine when clients supply information, when production occurs, when invoices are issued, and when payment arrives. The buyer hub connects this schedule with acquisition diligence and financing.

Do not assume the seller’s reported year-end bank balance is the buyer’s usable opening liquidity. Cash may be excluded from an asset purchase, distributions may occur before closing, and transferred balances may support obligations already incurred. Reconcile the closing agreement and bank records before treating a historical cash figure as funding for the buyer’s operation.

How should the collection calendar be built?

Use monthly bank receipts and billing detail across comparable service cycles. Reconcile them to accounting records and identify deposits, advance fees, old receivables, credits, and exceptional projects. Determine whether a strong month reflects current services or collection of work performed earlier. Invoice dates alone do not establish when cash is available.

Review major client cohorts and payment arrangements. Some clients pay at filing, others on delivery or through installments, and some business engagements have negotiated schedules. Document the actual agreements rather than imposing an assumed seasonality curve. Include recurring monthly revenue only when the underlying work and collection behavior support that treatment.

The historical Journal of Accountancy discussion of small-firm sale terms describes how collection and payment mechanics affect transactions. Use that framework to connect acquired receipts with seller payments, without adopting historical price ranges. The purchase-structure guide explains why obligations tied to collections still require precise timing and definitions.

What does an extension change in the cash forecast?

The IRS extension guidance distinguishes additional filing time from additional time to pay tax. For the practice, an extended return may shift work, billing, and collection beyond the initial filing period. The client’s tax-payment deadline and the firm’s fee-collection date are separate questions that should not be conflated.

Identify why returns were extended. Missing information, complexity, client preference, and limited production capacity have different operating implications. A backlog may bring future fees but also consume hours already needed for other work. Do not treat extension counts as free future revenue without reviewing remaining tasks, scope, fees, and staff availability.

Compare similar periods using completed work and open engagements. A current-year revenue decline may reflect timing, relationship loss, or both. Update the forecast after obtaining evidence, and preserve the original assumptions. Otherwise a buyer can mistake an unfinished service cycle for permanent loss or assume every delayed invoice will eventually be collected.

How should closing obligations be assigned?

Identify ownership of receivables, work in process, deposits, advance fees, payroll accruals, subscriptions, and vendor commitments. Establish which party performs unfinished work and receives the related fees. Determine how collections received into the wrong account are redirected and reconciled. These terms change the buyer’s opening cash requirement.

An advance fee may be cash on the closing balance sheet while representing services still owed. An old receivable may provide cash to the seller even though the buyer’s team helps resolve the collection. Model the agreement’s economics instead of counting every incoming payment as money available for buyer debt and living expenses.

Request a supported closing schedule and a practical reconciliation process. Assign who maintains records and resolves disputed amounts. Small balances can accumulate into a meaningful seasonal issue if treatment is ambiguous across many clients. A buyer should understand how the first months work before deciding the purchase requires only a down payment.

What would an illustrative liquidity calculation show?

These invented figures show timing, not a Midwest benchmark. Ending cash equals opening cash plus receipts minus payments. If month three’s receipts are delayed, the low month becomes more severe even though expected annual revenue is unchanged. Add transition spending and the buyer’s required reserve when evaluating how much opening funding is appropriate.

Seasonal liquidity trough means the lowest forecast cash balance during a service and collection cycle. Identify it under both the base and downside assumptions. Required funding should be tested against that low point and the obligations immediately following it, rather than the average bank balance across the year.

Which expenses should be scheduled before receipts?

Build the payroll calendar, employer costs, seasonal assistance, software renewals, office payments, insurance, loan payments, seller obligations, and transition fees. Include the buyer’s replacement duties and management needs. A seller who performed unpaid peak work may have kept payroll low in a way the successor cannot repeat.

Separate expenses already reflected in the seller’s financials from new acquisition costs. Avoid counting the same wage twice, but include additional review, training, and temporary coverage required during the handoff. The staff evaluation guide helps translate the acquired work calendar into funded capacity rather than assumed personal availability.

Consider payment dates and contract terms, not just annual expense totals. A large software renewal or insurance installment may fall during the weakest collection month. Verify whether contracts transfer and whether buyer setup changes billing. A forecast that spreads every cost evenly can obscure the actual funding gap.

How does retention risk change liquidity?

The historical Journal of Accountancy retention guidance emphasizes cooperation and relationship transfer. In the cash forecast, distinguish a permanent departure from a delayed appointment, smaller service scope, or slower payment. These events have different effects on receipts and may require different operating responses.

The retention-underwriting guide supports cohort-specific scenarios. Stress the loss or delay of relationships that carry meaningful seasonal collections. Use the cost behavior that actually follows: some variable assistance may fall, while regular payroll, rent, and debt payments continue. Revenue loss is not automatically offset by an equal percentage reduction in expenses.

Keep purchase adjustments separate from immediate liquidity. A later rebate or consideration reduction may improve the final economics but provide no cash for next week’s payroll. Determine when relief occurs and whether lender rules govern its treatment. Model available cash by date before relying on a contractual protection to bridge the seasonal trough.

What funding should be discussed before closing?

Identify buyer cash, acquisition funding, appropriate working-capital facilities, and an operating reserve. Obtain actual terms and lender review; do not assume a facility is committed or permits every intended use. Include interest and repayment timing in the forecast, and distinguish borrowing capacity from money already available.

The SBA 7(a) overview includes working capital among general permitted uses, subject to program and lender requirements. The SBA purchase guide addresses acquisition-specific conditions. Explain the forecast’s seasonal low point to the lender instead of requesting a round amount without showing when and why it is needed.

Retain a contingency tied to identified risks such as delayed collections or temporary coverage. The appropriate amount depends on evidence and obligations. It should not be justified by a universal percentage asserted without support. Revisit the plan if closing moves relative to the service calendar, since a different date can change the funding requirement.

What should the buyer monitor after ownership changes?

Review actual receipts, completed work, extensions, aged balances, upcoming payments, and staffing against the dated forecast. Explain variances promptly and update the lowest projected cash balance. A favorable annual outlook does not remove the need to act on a near-term shortage while practical financing or workload adjustments are still available.

Track whether the acquired billing process is operating as expected. Missing invoices, incomplete client information, payment-platform changes, or unclear contact responsibility can delay cash without immediate relationship loss. Assign corrective actions. Seasonal liquidity planning is useful when it supports delivery and decisions throughout the cycle, rather than existing only as a closing spreadsheet.
