A contractor with a CPA, doing everything "right," still overpaid by more than $22,000. How? His entity structure had never been revisited. His equipment timing was never planned. Family payroll was never set up. Estimated payments were on autopilot.
His CPA wasn't bad. His CPA was a historian — and he'd hired a historian to do an architect's job.
Filing your taxes and planning your taxes are two different jobs. Most owners only ever hire for one of them. Here's how to tell the three roles apart — and figure out which one you're missing.
What does a bookkeeper actually do?
A bookkeeper records what happened. Every month, they categorize your transactions, reconcile your bank and credit card accounts, and produce financial reports — profit and loss, balance sheet, cash flow.
Good bookkeeping answers: *Where did the money go? Which jobs made money? Can I afford this hire?*
But here's the deeper truth most owners miss: clean books don't just record the past — they reveal the future. A bookkeeper who hands you reports you actually read is giving you the raw material every other tax decision depends on. Without clean books, your CPA is guessing and your strategist has nothing to plan with.
You need a bookkeeper when: your books are months behind, you can't tell which jobs are profitable, or tax season means reconstructing a year from bank statements.
What does a CPA actually do?
A CPA reports what happened — correctly. They take your financials, apply the tax law, prepare your returns, and file them on time. A good CPA keeps you compliant, avoids penalties, and doesn't miss the deductions sitting in front of them.
Most CPAs are also generalists — and construction is a specialist's game. Percentage-of-completion accounting, retainage, underbillings and overbillings, equipment-heavy balance sheets, multi-state job sites: a preparer who doesn't speak construction will file a *correct* return that still leaves money behind.
The tell is in the questions they never ask. Did you buy equipment this year? When did you last revisit your entity? Are you tracking job costs cleanly? If your CPA never brings up strategy unprompted, you don't have a strategist — you have a filer. And there's nothing wrong with a filer, as long as you know that's what you hired.
You need a CPA when: you need returns prepared and filed correctly, and someone to keep you compliant with the IRS and the state.
What does a tax strategist actually do?
A tax strategist designs what happens next. Where the CPA looks backward at the year that's over, the strategist looks forward at the year that's still alive — because the big levers all expire on December 31.
A strategist asks: Should you elect S-corp status *this* year? Should that truck purchase happen in December or January? Is family payroll set up before the next pay cycle? Are your estimated payments matched to actual profit — or to last year's guess?
On a $300,000 profit, the gap between a 32% effective hit and a 25% one is roughly $21,000. That's not a rounding error. That's the difference between having a strategist and not having one.
You need a tax strategist when: your profit has grown past $150,000–$200,000, you're paying more tax every year without understanding why, or your spring CPA meeting is just a signature and a payment.
Why do contractors overpay even with a good CPA?
Because the system rewards whoever plans earliest, and almost every planning lever has a calendar:
- Equipment purchases must happen before December 31
- Hiring your kids must be set up before the wages are paid
- Entity elections have filing deadlines
- Estimated payments are due four times a year, not once
By April, the year is over and nearly every lever is gone. A CPA who meets you in March can only report what happened. The $22,000 that contractor overpaid wasn't hidden in some exotic loophole — it was sitting in plain sight, in strategies nobody planned in time.
How do you know which one you're missing?
Ask yourself the honest question: do my books tell me what to do next, or just what happened last? If it's only the past, you have records — not intelligence.
Then run the six-area diagnostic against last year. For each one, answer yes or no — *did we actively plan this?*
- Entity structure and owner salary
- Equipment depreciation and timing
- Home-related strategies (Augusta Rule, home office, accountable plan)
- Family payroll
- Retirement plan type and funding
- Estimated payment accuracy
Every "no" is a conversation to have before December 31. And if your current team can't have those conversations with you, you don't have a team problem — you have a missing role.
One practical note: you don't necessarily fire anyone to fix this. Many owners keep their bookkeeper for the monthly books and their CPA for filing — and add a strategist for the planning layer. The three roles stack. The expensive mistake isn't paying for all three; it's paying for one and expecting it to do the other two jobs.
Your move
At your next CPA meeting, ask three questions: *What construction-specific strategies apply to me this year? Are we maximizing 179 and bonus depreciation? When should we revisit my entity choice?* The answers will tell you everything about which role you're actually paying for.
