Key takeaways — A tax projection is only as good as the records behind it. Before anyone can tell you what you’ll owe, your books need to show income in the right period, loan principal split from interest, assets identified rather than lumped, owner draws kept separate, and payroll that agrees with what was actually filed. Without those, the number is a guess wearing a decimal point.
Somewhere around October, a lot of business owners ask their accountant a version of the same question: what am I going to owe?
It’s the right question, and it’s usually asked at the right time. But the answer depends less on tax law than most people expect, and more on something considerably less interesting — whether the books can support an answer at all.
A projection built on incomplete records isn’t conservative or cautious. It’s wrong in a direction nobody can predict, which is worse than having no number, because you’ll plan around it.
Why does a projection need clean books at all?
Disorganized records don’t change what you owe. They change how accurately anyone can see it.
Tax law applies to your actual income and your actual deductible expenses. Those facts already exist, recorded correctly or not. What poor records destroy is visibility — and visibility is the entire product a projection delivers.
Here’s what routinely distorts a year-to-date profit and loss statement:
Bank and credit-card accounts that haven’t been reconciled
Income recorded twice, or not recorded at all
Business expenses paid from a personal account
Personal spending sitting inside the company’s books
Loan payments booked entirely as expense
Payroll entries that don’t agree with the payroll reports
Large purchases recorded without identifying what was bought
Receivables that may or may not be collectible
Owner draws classified as something else
Any one of these will move net income. Several together will move it far enough that the P&L stops resembling the return.
The error runs both directions, which is the part owners tend to miss. Incomplete books can hide a liability you should have been reserving for. They can also invent one that isn’t there and talk you out of a hire, a purchase, or a distribution you could have made comfortably.
Why is my taxable income higher than the cash in my bank account?
Because cash and taxable profit measure different things, and several completely ordinary transactions reduce one without reducing the other.
This is the most common surprise we see, and it usually has nothing to do with bad bookkeeping. It’s structural.
Taxable income is what the tax law counts as profit for the year. Cash is what’s sitting in the account. A business can spend heavily all year, feel broke by December, and still owe tax on a real profit.
Every one of these is normal. None is a mistake. But an owner watching the balance fall month after month can reasonably conclude the business had a soft year, and be entirely wrong about it.
Cash in the account and taxable profit are not the same number. Any projection worth paying for explains the gap between them, rather than just reporting the total.
What must your books show before a projection is useful?
Seven things — and all seven have to be right, because an error in any one of them moves the answer.
1. Income, in the correct period. Sales, service revenue, deposits, and refunds recorded completely, and recorded in the year they actually belong to. Timing errors here are quiet and they compound.
2. Operating expenses, categorized and supported. Real categories with documentation behind them. A deductible business expense has to be both ordinary and necessary for your trade or business, per IRS Publication 334. Putting a transaction in a plausible category doesn’t establish either one.
3. Payroll that ties out. Wages, payroll taxes, benefits, and owner compensation should agree with what your payroll system actually filed. When the books and the filings disagree, the difference tends to surface at the least convenient moment.
4. Debt split into principal and interest. Interest is generally deductible. Principal reduces a liability on the balance sheet. Booking the whole payment as expense overstates your deductions and understates what you’re going to owe — often by a lot, early in a loan’s life.
5. Assets identified, not just paid for. A large purchase entered as a lump sum tells your accountant nothing about what it was. Whether it’s deducted now, capitalized, or depreciated over years depends on what the thing is and how the business uses it.
6. Owner transactions kept separate. Contributions, draws, distributions, shareholder loans, and expense reimbursements all behave differently. Collapsed into one another, they distort the P&L and the balance sheet at the same time.
7. Receivables and unpaid bills — if you’re on accrual. Under an accrual method, income counts when it’s earned and expenses when they’re incurred, so what’s outstanding genuinely matters. Under the cash method it generally doesn’t. Your accounting method decides which (IRS Publication 538).
Documentation carries as much weight as the categories. The IRS expects supporting records that show the payee, the amount, proof of payment, the date, and what was purchased (What kind of records should I keep?). That paperwork isn’t only an audit question. It’s what lets someone classify a transaction correctly the first time, instead of guessing at it in March.
What if the books are already behind?
Get them accurate before you get them perfect, and get a rough number early rather than an exact one too late.
The immediate goal isn’t a closed year. It’s a defensible year-to-date picture: accounts reconciled, missing income and expenses entered, personal and business transactions pulled apart, payroll confirmed, loans and large purchases reviewed, obvious misclassifications corrected. That’s usually enough to produce a preliminary projection.
If the cleanup moves projected profit materially — and it often does — the plan should move with it. That’s the point of doing it in the fall rather than the spring.
Waiting because the records feel embarrassing only shrinks the window you have to act. Books fall behind constantly, for ordinary reasons, at businesses that are otherwise run well. The useful question isn’t how it happened. It’s how quickly you can get to numbers you trust. If that’s where you are, monthly bookkeeping is usually the fix that keeps it from recurring — and it’s worth understanding what falling behind actually costs before deciding it can wait another quarter.
What can a projection actually tell you?
It should get you close enough to plan around. It won’t get you to the dollar, and you shouldn’t want it to.
A projection estimates the range you’re landing in and explains what’s driving it. That’s enough to decide whether to increase a reserve, adjust estimated payments, reconsider the timing of a purchase, or leave things alone.
What it can’t do is settle the final number. Your personal return, a spouse’s income, investment activity, credits, entity structure, and state obligations all move the result after the business figure is known. A projection that claims more precision than that is overselling.
The value isn’t the number. It’s having it early enough that you still have options — which is the whole distinction between tax planning and tax preparation. Preparation reports a year that’s already closed. Planning changes one that hasn’t.
Frequently Asked Questions
What is a tax projection?
A tax projection is an estimate of what you’ll owe for the current year, built from your year-to-date results and a forecast of the rest of the year. It’s used to size a reserve, adjust estimated payments, and evaluate decisions while there’s still time to act on them.
Why is my taxable income higher than the cash in my bank account?
Cash and taxable income measure different things. Loan principal payments, owner draws, equipment purchases, and inventory all reduce cash without producing an equal deduction this year. A business can be short on cash and still have real taxable profit.
How current do my books need to be for a projection?
Current enough that a year-to-date profit and loss statement is credible — accounts reconciled, income and expenses recorded, payroll agreeing with the filings, and owner transactions separated. Perfect isn’t required. Accurate is.
Does better bookkeeping lower my taxes?
Not on its own. It makes sure every expense you’re entitled to deduct is captured and supported, keeps unsupported items out, and surfaces planning opportunities early enough to evaluate. What you legally owe still depends on your facts and the law.
When should I get a tax projection?
Most owners are well served by one at midyear and another in the fall, before year-end decisions have to be made. Businesses with volatile, seasonal, or fast-growing income benefit from quarterly reviews. Update the books before each one.
If you’re heading into year-end without a reliable sense of what you’ll owe, the first step usually isn’t a tax conversation — it’s finding out whether your books can answer the question yet. FJ & Associates works with Utah business owners on both halves: getting the records to a state where a projection means something, then building the projection and the plan around it.
