Tax Season Capital Planner: How Much You Actually Need

Four short exercises. Do them in order with real numbers from your own practice — the output is a figure you can defend, not a guess.

Step 1 — Size the pre-season gap

Everything you will spend from 1 October to 31 January, before the season meaningfully bills:

LineYour number
Marketing (Oct–Jan)
Seasonal preparer payroll (through January)
Year-round payroll (4 months)
Software and e-filing renewals
Rent, utilities, insurance (4 months)
Workstations, equipment, extra space
Continuing education and licensing
Existing debt service (4 months)
A. Total outflow

Now the other side:

LineYour number
Cash on hand today
Off-season receipts expected Oct–Jan
Early-season billing landing before 31 Jan
B. Total available

A − B = your pre-season gap. If it is negative, you do not need capital for the season — you may still want it for growth, which is Step 2. If positive, that is the maximum you should consider, not a target.

Step 2 — Test the seasonal hire

Per preparer:

Your number
Fully loaded cost, Dec–Apr (wage, tax, training, workspace)
C. Cost
Returns they can realistically complete
Your average fee per return
D. Billings (returns × fee)
E. Cost of capital for the months you hold it

D − C − E = contribution per hire. Positive and comfortable, the hire funds itself. Thin, hire fewer. Negative, do not borrow to make it.

Be conservative on returns completed. A first-season preparer is slower than your veterans, and training time is cost before it is capacity.

Step 3 — Test the marketing spend

The common error is judging marketing against one return. A tax client is usually recurring.

Your number
Planned spend (Oct–Jan)
New clients you expect it to produce
F. Cost per new client (spend ÷ clients)
Average first-year fee
Average years a client stays
G. Lifetime fee (fee × years)

If G is several times F, the spend is justified even when year one roughly breaks even. If you do not know your retention, use two years — it is conservative for most practices.

Step 4 — Decide the amount and the shape

You now have a gap (Step 1) and a return test (Steps 2 and 3). Two rules:

Borrow the smaller of: the pre-season gap, or the amount whose return you demonstrated. Borrowing more than the gap costs you carry on money you do not need. Borrowing more than the return justifies costs you margin.

Match the shape to the timing. One pre-season investment taken once suits a lump sum. Costs landing in waves across October to January suit revolving capital you use as needed, so you are not paying for capital before you deploy it. The trade-offs are set out in funding options compared.

The stress test

Before committing, answer one question: if the season comes in 20% under plan, can you still meet the obligation?

If no, reduce the amount until the answer is yes. Seasons do disappoint — a late filing-rule change, a competitor opening nearby, weather in a drop-off market. A plan that only works at full volume is not a plan.

A worked example

A two-partner practice, 600 returns at a $340 average fee.

between them at $340 = $51,000 billings

fee. Justified.

They borrow toward the $48,000 gap, not the $80,000 they were offered, and structure it so the bulk is requested in December when payroll starts rather than October when it is only marketing.

At 20% under plan the hires still contribute and the obligation still clears. The plan survives its own stress test.

Frequently Asked Questions

How much should a tax practice borrow for the season?

The smaller of two numbers: the pre-season gap from Step 1 — everything you will spend between October and January minus the cash and receipts that will cover it — and the amount whose return you can actually demonstrate in Steps 2 and 3. Borrowing more than the gap means paying to carry money you do not need. Borrowing more than the return justifies costs you margin.

When should a tax firm apply for busy-season funding?

Work backwards from the first large cost rather than from the season. If seasonal payroll starts in December and marketing starts in October, an application in late October or early November leaves room to compare offers and to be funded before the money is needed. Applying in the week the cost lands removes every option but the fastest one.

What if the season comes in under plan?

Run that case before you commit. Take the obligation and ask whether it still clears at 20% below your expected volume. If the answer is no, reduce the amount until it is yes. With an MCA the repayment is a share of receipts, so a weaker season pulls proportionally less — but the obligation itself does not go away, and a plan that only works at full volume is not a plan.

How do I know whether a seasonal hire pays for itself?

Compare the preparer's fully loaded cost from December through April — wage, payroll tax, training time and workspace — against the returns they can realistically complete multiplied by your average fee, then subtract the cost of the capital for the months you hold it. Be conservative on returns completed: a first-season preparer is slower than a veteran, and training is a cost before it is capacity.

Is marketing spend before the season worth borrowing for?

It depends on retention, not on the first return. Divide the planned spend by the new clients you expect it to produce to get a cost per client, then compare that against the average fee multiplied by the number of years a client stays. If the lifetime figure is several times the acquisition cost, the spend is justified even when year one roughly breaks even. If you do not know your retention, use two years — it is conservative for most practices.

Should we take a lump sum or revolving capital?

Match the shape to the timing. One pre-season investment made once suits a lump sum. Costs that arrive in waves across October to January — marketing, then payroll, then software renewals — suit revenue-based revolving capital you request as needed, so you are not paying to hold capital before you deploy it.


Numbers are illustrative. Your fee, retention and cost structure are the only ones that matter. Funding availability and terms depend on file fit; approval is never guaranteed in advance.
