Small business tax advisor, nationwide
A tax accountant for small business owners who models the decision during the year, then files the return that reflects it. CPA-led, connected to your books and payroll, delivered securely to every state.
Best for owners with roughly $250K+ in revenue or profit who will make decisions during the year. Not the lowest-cost annual filing option.

The short answer
A small business tax advisor is a CPA who models decisions while they are still open: entity choice, owner pay, retirement contributions, purchases, and estimated payments. A tax preparer records what already happened. Taxstra does both, nationwide, with written recommendations that connect the books, the payroll, and the return.

Roles, defined
Yes. They look at different things, on different schedules, and hand you different outputs. Most small businesses have a preparer and think they have an advisor.
A tax preparer takes the year that already happened and puts it on the right forms. A tax accountant keeps the ledger accurate so that return is right. A tax advisor for small business owners sits upstream of both: while the year is still open, the advisor projects the tax bill under two or three options and tells you which one to take and by when.
The three roles are not competing. The best result is when one firm covers all three from a single set of books, so the advice in June matches the return in March.
| Role | Looks at | Cadence | Typical output |
|---|---|---|---|
| Tax preparer | Last year, after it closed | Once a year, at filing | A filed return and an invoice |
| Tax accountant | This year, transaction by transaction | Monthly close | Reconciled books, financial statements, clean 1099s and payroll |
| Small business tax advisor | This year and next, while choices are open | Quarterly planning meetings plus decision calls | Written recommendations with owners, deadlines, and a projected tax bill |
| Taxstra (all three) | Books, payroll, plan, and return together | Monthly books, quarterly planning, annual filing | One fact pattern from decision to return |
The cadence
Four checkpoints, each tied to a deadline you can still influence. Planning that only happens in December leaves half the moves on the table.
Estimated payment dates follow the IRS Form 1040-ES schedule and shift to the next business day when they land on a weekend or holiday. The point of the calendar is not the dates. It is that every meeting happens while the decision is still live.
| When | What we look at | Decisions on the table |
|---|---|---|
| January to March | Prior-year close, first-quarter projection, entity and election review | S corporation election by March 15 for calendar-year entities, retirement plan funding for the prior year, first estimate due April 15 |
| April to June | First-half actuals against the projection, payroll and owner pay | Reasonable salary adjustments, second estimate June 15, hiring and equipment timing |
| July to September | Year-to-date profit, cash, multi-state exposure | Third estimate September 15, retirement plan selection before setup deadlines, state registrations |
| October to December | Full-year projection with real numbers | Year-end purchases, bonus and distribution timing, charitable and family strategies, fourth estimate January 15 |

What gets modeled
The same handful of decisions drive most of the savings for owner-operated businesses. The value is in modeling them with your numbers, not in knowing they exist.
We project self-employment tax against a reasonable salary, payroll cost, and state treatment before recommending an election. A sole proprietor netting $150,000 pays self-employment tax on nearly all of it; the same owner as an S corporation pays payroll tax only on the salary portion. Whether that gap covers the added payroll and compliance cost is the question we answer.
For S corporation owners, salary is the single most examined number on the return. We document the reasonable compensation analysis so it holds up, then set distributions around it.
Solo 401(k), SEP IRA, SIMPLE IRA, or a defined benefit plan for owners with high, steady profit. We compare contribution room, employee cost, and setup deadlines so the plan is in place before the year ends.
Equipment purchases, bonus depreciation versus Section 179, prepaying expenses under the 12-month rule, and shifting income between years when brackets differ. All of it modeled in October with real year-to-date numbers, not guessed in December.
Ask any advisor to show you the projection, not just the recommendation. A one-page comparison of "as is" versus "with the change" for this year, with the assumptions listed, is the deliverable. If a firm cannot produce that, it is selling preparation with a planning label.

Local or remote
Taxstra has an office in Springfield, IL, and serves owners in every state through a secure portal. For most businesses, "near me" should mean the firm knows your state, not that it is on your block.
Searching for a small business tax advisor near me makes sense when the work depends on physical presence: an inventory count, a local licensing issue, a walk-in meeting. Everything else, from planning meetings to signatures to document exchange, happens in a portal and on video today, whichever firm you pick.
What actually matters is state expertise and responsiveness. An advisor who has handled your state's pass-through entity tax election, its payroll registration, and its nonresident owner rules is more useful than one down the street who has not. So is a firm that returns a question in a day instead of after April 15.
If you are in central Illinois and want to sit across a table, we are here. If you are anywhere else, searching for small business tax planning near me will get you a shorter drive, not better advice.

Fees
It depends on scope. Advisory is priced on the decisions in play and the complexity of the entity, not by the form.
Market ranges for small business advisory run from a few thousand dollars a year for a single-entity owner with quarterly planning to well above that when books, payroll, multiple entities, or multi-state filings are bundled in. Taxstra quotes a fixed fee in the engagement letter after the free initial consultation, once we have seen the entity and the books. The two guides below walk through what drives the number.
