The $80K S-Corp Threshold Is a Myth

Stop asking, “How much profit do I need for an S-Corp?” That’s the wrong question. The $80K–$100K “S-Corp threshold” is a myth.

One of the most common rules of thumb in small-business tax planning is that you should wait until your business earns $80,000, $100,000, or some other arbitrary amount of profit before considering an S-Corp election.

That sounds simple. It is also the wrong way to think about the decision.

Net profitability doesn't matter at all. What matters is the difference between your Reasonable Compensation and your net profitability.

The S-Corp tax benefit comes from the portion of business profit that can legitimately remain after paying the owner Reasonable Compensation for the work he or she performs. That remaining amount can generally be distributed without being subjected to Social Security and Medicare payroll taxes.

So the important number isn't simply how profitable the business is. It is how much room exists between the business's profit and the salary the owner must reasonably pay himself.

The only thing that matters is the delta between net profit and your reasonable salary. e.g. if you are a dentist with 150K net profit and a 140K reasonable salary, you are only going to save $1,500 [ 150K - 140K = 10K * 15% ] , which is not going to be enough savings to justify having to run payroll and file a corporate tax return.

That dentist may have what sounds like a very profitable business. But if nearly all of that profit represents compensation for the dentist's own labor, there simply isn't much profit left to treat as an S-Corp distribution.

A business with $150,000 of profit, therefore, isn't automatically a good S-Corp candidate.

The reverse can also be true.

On the other hand if you are making 60K net profit and can justify a 10K salary (perhaps its part time work) then that gives you 40K delta * 15% = 6K -- is probably enough to justify the expense of running an S - Corp.

There is an arithmetic issue in that example: $60,000 minus $10,000 is a $50,000 delta, which would produce approximately $7,500 of payroll-tax savings using the same 15% shorthand. But the underlying point remains the same.

A business earning only $60,000 could potentially produce more S-Corp tax savings than a business earning $150,000.

That is why profit thresholds are misleading.

You always hear about the 80K-100K profit threshold for saving money on an S-Corp. That is FALSE! Net profitability doesn't matter at all. What matters is the difference between your Reasonable Compensation and your net profitability.

The only thing that maters is the delta between net profitability and your reasonable salary. e.g. if you are a dentist with 150K net profit and a 140K reasonable salary, you are only going to save $1,500 [ 150K - 140K = 10K * 15% ] , which is not going to be enough savings to justify having to run payroll and file a corporate tax return. On the other hand if you are making 60K net profit and can justify a 10K salary (perhaps its part time work) then that gives you 40K delta * 15% = 6K -- is probably enough to justify the expense of running an S - Corp.

The Better Question

Instead of asking:

“How much profit does my business need before an S-Corp makes sense?”

Ask:

“What is the difference between my business's expected profit and a defensible Reasonable Compensation amount?”

That difference—the delta—is where the potential payroll-tax savings live.

If the delta is only $10,000, the potential savings may be too small to justify payroll processing, an additional business tax return, bookkeeping requirements, state filings, and the other administrative costs of operating an S-Corp.

If the delta is $40,000, $50,000, or $100,000, the economics can look very different.

Reasonable Compensation Drives the Calculation

This is also why choosing an arbitrary salary percentage doesn't work.

Reasonable Compensation is supposed to reflect what the shareholder-employee should be paid for the services actually performed. The nature of the work, hours spent working, responsibilities, experience, local wage data, and the different roles the owner performs can all affect the answer.

A full-time professional whose business income is primarily generated by his or her personal services may need a relatively high salary.

A business owner working only a few hours per week—or whose company generates substantial income from employees, equipment, intellectual property, or other business assets—may have a very different compensation profile.

That is why two businesses with exactly the same net profit can have dramatically different S-Corp savings.

Forget the Threshold. Calculate the Delta.

There is nothing magical about $80,000.

There is nothing magical about $100,000.

The real S-Corp decision is an economic comparison:

Net profit − Reasonable Compensation = potential distribution

Then compare the payroll-tax savings associated with that distribution against the additional cost and complexity of operating the S-Corp.

That is the calculation that tells you whether the election actually makes sense.
