The eight questions every US small-business owner should ask their accountant for tax season are: (1) What deductions am I missing? (2) Am I in the right entity structure? (3) Are my estimated quarterly payments correct? (4) What records do you need — and how should I keep them? (5) How do my loans, advances, and interest affect my return? (6) Can I still make retirement or equipment moves before year-end? (7) What is my real effective tax rate and next-year plan? (8) How do I handle payroll, 1099s, and sales tax cleanly? Ask these before the filing crunch, because most of the moves that lower a bill have to happen in the tax year itself, not in April. This guide walks through each question the way an underwriter reads a file — looking at cash flow, documentation, and what the numbers really say about the business.
Key takeaways
- The most valuable tax questions are planning questions asked in Q3-Q4 — by filing season, most money-saving moves are already closed.
- Credits reduce your tax dollar-for-dollar and are generally worth more than deductions of the same size.
- A tax extension delays filing, not payment — you generally still owe the estimated amount by the original deadline.
- Interest on business financing is generally deductible; principal is not, and advance fees are booked differently — confirm each is recorded correctly.
- Aggressively minimizing taxable income can also shrink the income a bank lender sees, potentially lowering what you qualify for.
- Revenue-based and MCA marketplaces approve on bank deposits and revenue (from ~$10,000, FICO 500+, decisions in ~24-48 hours), not primarily on your tax return — never guaranteed.
- Clean, contemporaneous records serve double duty: an accurate return and a fast, fair financing decision.
Why these questions matter more than the refund
Most owners walk into a tax meeting asking one thing: "How much do I owe?" That is the least useful question in the room. By the time the return is being prepared, the tax year is closed and your options have narrowed to a handful of retirement and accounting elections. The real value of an accountant shows up in planning conversations — the ones that happen in Q3 and Q4, before the books lock.
From an underwriting seat, we read hundreds of tax returns and bank statements a year, and the pattern is consistent: the businesses that keep the most cash are not the ones with the fanciest strategies. They are the ones whose owners asked good questions early, kept clean records, and understood how their financing showed up on the return. The eight questions below are ordered the way we would triage a file — structure and documentation first, then the moves that change the number.
If you are also weighing how a tax bill or a seasonal cash gap affects your ability to grow, it helps to understand your financing options in parallel. Our small business financing guide lays out how lenders and revenue-based marketplaces actually evaluate a business, which is directly relevant to several of the questions here.
The 8 questions, one at a time
1. What deductions or credits am I leaving on the table?
Ask your accountant to review the categories owners most often miss: home-office use, vehicle mileage, a portion of your phone and internet, professional development, business insurance, bad debt, and startup costs from prior years. Then ask about credits, which are worth more than deductions dollar-for-dollar — the research credit, work-opportunity credit, and any state-specific incentives. Bring a full year of statements so the conversation is grounded in real spending, not memory.
2. Am I in the right entity structure for how I actually operate?
Sole proprietor, partnership, S-corp, C-corp, or LLC taxed as one of those — the right answer depends on your profit level, how much you pay yourself, and your growth plans. A common turning point is when a profitable LLC elects S-corp status to split income between salary and distributions. Ask: "At my current and projected profit, does my structure still make sense, and what would a change cost to implement and maintain?"
3. Are my estimated quarterly payments on track?
Underpaying triggers penalties; overpaying hands the government an interest-free loan while your own cash sits idle. Ask your accountant to recalculate your quarterlies against actual year-to-date income, not last year's numbers, especially if you had a strong or slow stretch. This single question protects cash flow more than almost any deduction.
4. What records do you need, and how should I keep them year-round?
Ask for a specific list — bank and card statements, loan and lease agreements, payroll reports, 1099s, mileage logs, receipts above a threshold — and a preferred format. Then ask how to keep them so next year is painless. Clean, contemporaneous records also matter far beyond taxes: they are the first thing an underwriter looks at when you apply for capital.
5. How do my loans, advances, and financing costs affect my return?
This is the question owners skip most, and it directly affects both your tax bill and your future borrowing. Interest on a business loan is generally deductible; principal is not. The fees on revenue-based financing or a merchant cash advance are treated differently and should be booked correctly so your profit-and-loss statement is accurate. Ask your accountant to confirm how each financing product on your books is being recorded — miscategorizing it distorts both your taxes and the financial statements a lender will read later.
6. Can I still make year-end moves before the books close?
Depending on timing, you may be able to fund a retirement plan (SEP-IRA, Solo 401(k), or similar), purchase and place equipment in service to use Section 179 or bonus depreciation, or prepay certain expenses. Ask which of these applies to you and what the deadlines are — some close on December 31, others extend to the filing deadline.
7. What is my effective tax rate, and what is next year's plan?
Ask your accountant to show your real effective rate — total tax divided by total income — not the marginal bracket. Then ask for one or two specific actions to take before the next tax year begins. A tax meeting that ends without a forward plan is only half finished.
8. How should I handle payroll, contractors, and sales tax cleanly?
Worker misclassification and sales-tax nexus are two of the most expensive mistakes a growing business makes. Ask whether your 1099 contractors are correctly classified, whether you are collecting sales tax everywhere you now have nexus, and whether your payroll withholding is current. Getting these wrong creates liabilities that compound quietly.
A tax-season prep timeline (for example)
Timing is the difference between planning and paperwork. Here is a realistic cadence — the figures and dates are examples to illustrate the rhythm, not fixed rules for your business.
| Period | What to ask / do | Why it matters |
|---|---|---|
| Q3 (Jul–Sep) | Mid-year check-in; recalculate estimated payments | Time to adjust before year-end while options are still open |
| Oct–Nov | Entity review, retirement plan setup, equipment planning | Some plans (for example, a Solo 401(k)) must be established before Dec 31 |
| December | Place equipment in service; final deduction moves; confirm financing is booked correctly | Most tax-year moves close on Dec 31 |
| Jan–Feb | Gather records; collect and issue 1099s | 1099s are generally due to recipients by end of January |
| Mar–Apr | File or extend; set next-year plan | An extension buys time to file, not time to pay |
An extension is worth underscoring: it postpones the paperwork, not the payment. If you expect to owe, you generally still need to pay the estimated amount by the original deadline to avoid penalties and interest.
Decision framework: when to plan solo vs. lean on your accountant
Not every business needs the same depth of tax help. Use this to decide how much to invest in professional planning.
A deeper accountant relationship works best when:
- Your profit has grown to where entity structure genuinely moves the number
- You have payroll, contractors, or sales-tax obligations across states
- You carry financing and want it booked correctly for both taxes and future borrowing
- Income is seasonal or lumpy, making estimated payments hard to get right
- You are planning a big equipment purchase, a sale, or bringing on partners
You can keep it lightweight when:
- You are a single-owner service business with simple, steady income
- You have no employees and few large deductions
- Your records are already clean and your structure is settled
The tell is complexity, not revenue. A $200k contractor with payroll, equipment, and multi-state sales needs more planning than a $400k solo consultant with a laptop and clean books.
How your tax return doubles as a financing document
Here is what most owners do not realize: the return you file is one of the primary documents lenders and revenue-based marketplaces use to size your capital. That creates a real tension. Aggressively minimizing taxable income lowers your bill today but can also shrink the income a traditional lender sees, potentially reducing what you qualify for later. It is worth asking your accountant to weigh both sides for your situation.
This is one reason revenue-based financing has become a practical option for many operators. Instead of leaning primarily on a tax return and credit score, a revenue-based or MCA marketplace approves on bank deposits and actual revenue — it reads the cash flowing through your accounts. Typical parameters we see are funding from around $10,000, credit profiles from roughly FICO 500 and up, and decisions in about 24 to 48 hours once statements are in. Nothing is ever guaranteed, and terms depend on your revenue and deposit history — but for a seasonal business or one that writes down income for tax purposes, being evaluated on cash flow rather than a single return can open a door that bank underwriting closes.
The practical takeaway: keep your bank statements clean and your financing booked correctly (question 5), because those two things drive both an accurate return and a fast, fair funding decision. If a tax bill lands larger than expected and threatens working capital, cash-flow-based financing can bridge the gap without forcing you to unwind good tax strategy.
Common mistakes that cost owners real money
- Treating the accountant as a filer, not an advisor. The value is in the planning conversation, and it has to happen before year-end.
- Commingling personal and business funds. It muddies deductions, weakens your records, and makes both audits and funding applications harder.
- Booking financing costs wrong. Confusing principal and interest, or mislabeling advance fees, distorts your P&L and your taxes.
- Ignoring estimated payments until April. Penalties and a cash crunch are avoidable with a mid-year recalculation.
- Assuming an extension delays payment. It does not — the payment is still due at the original deadline.
- Misclassifying workers. Calling an employee a contractor is one of the costliest quiet errors in small business.
Frequently asked questions
When should I schedule my tax-season meeting with my accountant?
Ideally twice: a planning check-in in Q3 or Q4 while you can still make moves that lower the bill, and a filing meeting in Q1. The planning conversation is where most of the savings happen, because once the tax year closes your options narrow to a few retirement and accounting elections.
What documents should I bring to my accountant?
A full year of bank and credit-card statements, all loan and lease agreements, payroll reports, 1099s you issued and received, mileage logs, receipts above your accountant's threshold, and prior-year returns. Ask your accountant for their exact list and preferred format so next year is faster.
Does taking a business loan or advance affect my taxes?
Yes, in how the costs are recorded. Interest on a business loan is generally deductible while principal is not, and fees on revenue-based financing or a merchant cash advance are treated differently. Ask your accountant to confirm each financing product on your books is categorized correctly so your P&L and return are accurate.
Is it better to minimize my taxable income as much as possible?
Not always. Lowering taxable income cuts this year's bill, but it also reduces the income a traditional lender sees on your return, which can shrink what you qualify for later. It is a genuine trade-off worth discussing with your accountant if you expect to seek financing.
How is revenue-based financing evaluated differently from a bank loan?
A bank leans heavily on your tax return and credit score. A revenue-based or MCA marketplace approves primarily on your bank deposits and actual revenue — it reads the cash moving through your accounts. Common parameters are funding from around $10,000, FICO 500 and up, and decisions in about 24 to 48 hours. Terms depend on your revenue and nothing is guaranteed.
What is the difference between a deduction and a credit?
A deduction lowers the income you are taxed on; a credit lowers your tax bill directly, dollar-for-dollar. That makes credits generally more valuable than a deduction of the same amount, so ask your accountant which credits your business qualifies for.
Does filing an extension give me more time to pay?
No. An extension gives you more time to file the paperwork, not more time to pay. If you expect to owe, you generally still need to pay the estimated amount by the original deadline to avoid penalties and interest.
Do I really need an accountant if my business is simple?
If you are a single-owner service business with steady income, no employees, and clean records, you may only need light help. The need grows with complexity — payroll, contractors, multi-state sales tax, financing on the books, seasonal income, or planned equipment purchases all make professional planning worth the cost.
