S corporation CPA services, nationwide and remote
An S corp accountant who handles election timing, reasonable compensation, payroll, distributions, shareholder basis, state elections, and the corporate and owner returns as one engagement.
Best for profitable owner-operated businesses that already are, or are considering becoming, S corporations. Not positioned as a low-cost return-only service.

The short answer
An S corp CPA is a tax accountant who manages the S corporation all year, not just at filing: whether and when to elect, what the owner should be paid, how payroll and health insurance are reported, how distributions and basis are tracked, and which state elections make sense. Taxstra does this remotely for owners in every state.

How to choose
An S corp CPA is a tax accountant who manages the entity all year: election timing, reasonable compensation, payroll, distributions, basis, and state elections, so that the corporate return and the owner return are the result of decisions, not surprises.
| Decision | Generalist preparer | S corp CPA |
|---|---|---|
| Election timing | Elects because the owner asked, or never raises it | Models profit, payroll cost, state fees, and benefits before recommending an election year |
| Reasonable compensation | Accepts whatever salary the owner set | Documents a defensible wage each year from comparable data and the business facts |
| Payroll | Assumes a payroll company has it handled | Reconciles W-2 wages, deposits, and the corporate deduction; fixes owner health insurance reporting |
| Distributions and basis | Reports distributions and moves on | Tracks stock and debt basis so distributions and losses are treated correctly |
| State treatment | Files the home state return | Registers where required, evaluates pass-through entity elections, plans for entity-level state costs |
| Late or broken elections | Discovers the problem at filing | Requests relief with a reasonable-cause statement, or fixes the eligibility issue before it terminates the election |
Taxstra is a remote CPA firm serving 1,000+ clients nationwide, led by Bryan Martin, CPA, MBA. S corporation work is a core part of the practice: the same team keeps the books, runs the projections, coordinates payroll, and files the corporate, owner, and state returns.
Elect on purpose
The election is worth making when sustained profit is high enough that the payroll tax saved on distributions clearly exceeds the added payroll, compliance, and state costs. That is a modeling question, not a rule of thumb.
The mechanics are simple: an eligible entity files Form 2553, and if it is filed within the first two months and fifteen days of the tax year, the election takes effect for that year. Filed later, it generally takes effect the following year unless late-election relief applies. The judgment is in the timing. An owner whose profit is still climbing may be better served waiting a year; an owner with stable, high profit who has been operating as a sole proprietor may already be a year late.
Before recommending an election, Taxstra models the owner wage, the payroll tax and payroll service cost, the separate corporate return, state fees or entity-level taxes, the effect on retirement plan contributions, and the effect on the qualified business income deduction. If the net result is small or negative, we say so.

The number the IRS looks at first
A shareholder who works in the business must be paid reasonable wages before taking distributions. Getting this number wrong in either direction is the most common S corporation mistake we see.
The IRS position is that officers who provide services to the corporation are employees, and that distributions cannot be used to avoid payroll tax on what is really compensation for services. Set the wage too low and the exposure is reclassification of distributions as wages, with payroll taxes and penalties attached. Set it too high and the owner overpays payroll tax every year without noticing.
Taxstra documents reasonable compensation annually using comparable wage data, the owner's actual duties and hours, the size and profitability of the business, and the return on invested capital. That documentation sits in the file before the return is prepared. We then coordinate payroll so the W-2, the payroll tax deposits, and the wage deduction on the corporate return match.
Owner health insurance is a frequent payroll error. Premiums paid for a more-than-two-percent shareholder must be reported as wages on the W-2 for the shareholder to claim the deduction on the personal return. A payroll setup that misses this costs the owner the deduction.

Basis decides the tax
Distributions are generally tax-free only to the extent of the shareholder's stock basis, and losses passed through on the K-1 can be deducted only to the extent of stock and debt basis. Basis moves every year with income, losses, contributions, distributions, and shareholder loans. When nobody tracks it, distributions that should have been taxable go unreported, or deductible losses get suspended by default because the preparer cannot prove basis. Shareholders now report basis on a dedicated IRS form in many situations, which makes a contemporaneous schedule a compliance requirement rather than a best practice.
Taxstra maintains a basis schedule for every shareholder, reconciles distributions to the books, and prepares the corporate return, the K-1s, and the owner return as one coordinated engagement so the numbers agree.

The state layer
Federal S status does not settle the state questions. Registration, entity-level taxes, nonresident owner obligations, and pass-through entity tax elections are decided state by state.
Many states let an S corporation elect to pay state income tax at the entity level, which can restore a federal deduction that would otherwise be limited on the owner return. Eligibility, deadlines, and payment mechanics differ by state, and the election is not always favorable.
Some states charge S corporations a franchise tax, minimum fee, or entity-level income tax regardless of the federal election, and a few require a separate state election. These costs belong in the election model.
Working, hiring, or owning property in another state can create registration and filing obligations for the corporation and withholding or composite obligations for nonresident owners.
When an owner moves, the sourcing of wages and pass-through income, the state credit interaction, and any pass-through entity election all need to be revisited.

Wages drive the plan
For an S corporation shareholder-employee, retirement plan contributions are based on W-2 wages, not on distributions. Employee deferrals come out of salary, and employer contributions are limited to a percentage of that salary. This is one of the reasons reasonable compensation is a planning decision and not just a compliance one: the wage that minimizes payroll tax may also cap the retirement contribution the owner wanted to make.
Taxstra coordinates the plan choice, the contribution timing, and the payroll setup so the deposit limits, the deduction, and the W-2 reporting all line up before year-end.

One team, one set of numbers
Monthly bookkeeping with reconciled bank, credit card, payroll, and owner activity, so distributions and basis are visible during the year.
Owner wages set from the reasonable compensation analysis, health insurance reported correctly, deposits and filings reconciled to the return.
Quarterly projections that update estimates, test the wage, and flag when an election, a plan contribution, or a state election should change.
Corporate return, K-1s, owner return, and state returns prepared by the same team from the same records, with basis schedules carried forward.
Taxstra is not the right fit for an owner who wants an S corporation only to skip payroll, or who is looking for the lowest-cost annual return. The value comes from running the entity properly all year.
The working relationship
Review profit history, current structure, payroll, prior elections, basis records, states, and benefits to see what the S corporation is doing today.
Model the election year, the reasonable compensation range, payroll and state costs, retirement contributions, and the effect on the owner return.
File or repair the election, set up or correct payroll, document reasonable compensation, register in the right states, and make any pass-through entity elections.
Close the books, update projections quarterly, roll basis forward, and prepare the corporate, owner, and state returns from one set of records.
