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.

Year-end 2026

Before December 31, 2026: moves that close at year-end

These decisions lock in when the calendar turns. After December 31, they become 2027 decisions.

  1. 1

    Run owner payroll in 2026

    If you own an S corporation and work in it, reasonable compensation has to be paid as W-2 wages. Wages count in the year they are paid, so a salary you skipped cannot be backdated into a January payroll.

  2. 2

    Put 2% shareholder health insurance on the W-2

    Health premiums the S corporation pays for a more-than-2% shareholder belong in that owner's W-2 wages. That is what allows the self-employed health insurance deduction, so it has to be in the final 2026 payroll.

  3. 3

    Max 401(k) deferrals through December payroll

    If you take W-2 wages, 2026 employee deferrals (up to $24,500, plus $8,000 at age 50 or older, or $11,250 at ages 60 to 63) must come out of wages paid in 2026.

  4. 4

    Place equipment and vehicles in service

    Section 179 and bonus depreciation apply only to property placed in service by December 31. A vehicle still at the dealer on New Year's Eve is a 2027 deduction. See which vehicles over 6,000 lbs qualify.

  5. 5

    Clear accountable plan reimbursements

    Reimburse home office, mileage, and phone costs under a written accountable plan before the books close, so the company deducts them and you receive them tax-free. How an accountable plan works.

Registrations, nonresident owners, and pass-through entity elections handled state by state

A strong fit

  • Profitable owner-operated businesses considering an S election

  • Multi-state S corporations or owners who have moved states
  • Owners who want books, payroll, and returns handled by one team

Probably not the right fit

  • A business with little or inconsistent profit
  • An owner who wants an S corporation in order to avoid payroll
  • A return-only engagement where price is the only criterion
  • A legal entity question without counsel involved

Reasonable compensation

What the right CPA delivers for an S-Corp salary

The right CPA for an S-Corp salary question builds a written compensation file, not a rule of thumb. That file ties your salary to the work you actually do, current comparable pay from sources such as BLS wage data, your hours, and the profit left after salary. The firm should also run payroll and prepare Form 1120-S so the number holds up. Taxstra sets and documents owner salaries for S-Corps in all 50 states.

How to choose

What an S corp CPA should do that a general tax preparer will not

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.

  • Ask how they set and document reasonable compensation, and how often they revisit it
  • Ask who prepares payroll and who reconciles it to the corporate return
  • Ask whether they track shareholder basis every year, not only when there is a loss
  • Ask how they evaluate state pass-through entity elections for your states
  • Ask what they would do if you had missed the election deadline

Why owners work with Taxstra

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

S corp election timing: when to file, and when to wait

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

Reasonable compensation and owner payroll

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, shareholder basis, and the owner return

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.

  • Stock and debt basis rolled forward annually
  • Distributions reconciled to bank activity and the balance sheet
  • Owner loans documented so they hold up as debt basis
  • K-1s issued with the basis information the owner return needs
  • Corporate and owner returns prepared together, not by two firms

The state layer

State pass-through entity elections and multi-state S corps

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.

Pass-through entity tax elections

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.

PTET workaround guide

Entity-level state taxes and fees

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.

California S corp example

Registration and nexus

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.

Owner residency changes

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.

Go deeper: LLC vs S corp

Wages drive the plan

Retirement plans and benefits through the S corp

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

How Taxstra works with S corp owners

Books that close

Monthly bookkeeping with reconciled bank, credit card, payroll, and owner activity, so distributions and basis are visible during the year.

Payroll coordinated with the plan

Owner wages set from the reasonable compensation analysis, health insurance reported correctly, deposits and filings reconciled to the return.

Projections before decisions

Quarterly projections that update estimates, test the wage, and flag when an election, a plan contribution, or a state election should change.

Coordinated returns

Corporate return, K-1s, owner return, and state returns prepared by the same team from the same records, with basis schedules carried forward.

What this is not

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

How the engagement works

  1. 01

    Entity diagnostic

    Review profit history, current structure, payroll, prior elections, basis records, states, and benefits to see what the S corporation is doing today.

  2. 02

    Election and wage model

    Model the election year, the reasonable compensation range, payroll and state costs, retirement contributions, and the effect on the owner return.

  3. 03

    Implementation

    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.

  4. 04

    Operate and file

    Close the books, update projections quarterly, roll basis forward, and prepare the corporate, owner, and state returns from one set of records.

Frequently Asked Questions

What is the best CPA for an S-Corp owner who needs help setting a reasonable salary?

One that documents the salary with evidence, runs or coordinates payroll, and files the Form 1120-S, so the number is supported and reported the same way everywhere. Taxstra does all three for owner-operated S-Corps in all 50 states.

Is there a percentage rule for S-Corp salary?

No. The IRS looks at what you would pay someone else for the same services, using factors such as training, duties, time devoted, and comparable pay. Rules of thumb like 60/40 have no IRS basis.

How often should my S-Corp salary be revisited?

At least once a year, and whenever your role, hours, or profit change materially. The file should show the evidence for each year's number.

What does an S corp CPA do?

An S corp CPA handles the pieces a general preparer usually leaves to the owner: deciding whether and when to elect, documenting reasonable compensation, running or supervising owner payroll, tracking stock and debt basis, coordinating the corporate return with the owner return, and handling state registrations and pass-through entity elections. The return itself is the last step, not the whole job.

When does the S corp election have to be filed?

For an election to take effect for a given tax year, Form 2553 is generally due within the first two months and fifteen days of that year. File later and the election normally takes effect the following year unless the entity qualifies for late-election relief. Timing the election around actual profit, not the calendar, is one of the main reasons owners hire an S corp CPA.

I missed the deadline. Can I still elect S corp status for this year?

Often, yes. The IRS provides a relief procedure for late S corporation elections when the entity intended to be an S corporation, has reasonable cause for filing late, and meets the other requirements. The relief request is made on Form 2553 with a reasonable-cause statement. Whether it fits your facts is a judgment call, which is why it should be reviewed before anything is filed.

How is reasonable compensation determined?

The IRS expects a shareholder who performs services for the corporation to be paid reasonable wages before taking distributions. There is no published percentage. Reasonable compensation is supported by what comparable professionals earn for comparable work, the time and duties involved, and the business economics, and it should be documented each year rather than set once and forgotten.

Do I need a separate payroll provider?

You need payroll, but not necessarily a separate relationship. Taxstra coordinates owner payroll, payroll tax filings, and year-end W-2 reporting with the books and the returns so that the salary on the W-2, the payroll tax deposits, and the deduction on the corporate return all agree.

Does an S corp work the same way in every state?

No. Some states impose an entity-level tax or fee on S corporations, some do not recognize the federal election automatically, and many now offer an elective pass-through entity tax. An S corp CPA models the state cost before the election is made, not after the first state notice arrives.
