A Korean corporate research institute decision starts with staffing but ends with incremental cash flow

The first visible threshold for establishing a recognized corporate research institute in South Korea is the number of dedicated researchers.
A small enterprise within its first three years can begin with two qualified researchers, while the ordinary minimum rises to three for a small enterprise, five for a medium enterprise under Korean SME rules, seven for a mid-sized enterprise, and ten for another enterprise.
A dedicated R&D department can use a one-person route, but that route should not be assumed to receive every form of support available to a corporate research institute.

Headcount alone does not answer whether the project creates value.
The business also needs to budget added salary, employer on-cost, independent research space, equipment, internal preparation, and recurring compliance work.
It then needs to distinguish a potential research and human-resources development tax credit from the smaller amount that can actually reduce current-year tax after tax liability, minimum tax, and other reliefs are considered.

This calculator joins those questions in one Korea-specific model.
It compares current and planned qualified researchers with the statutory minimum, gates recognition-linked benefits behind a qualification, dedicated-duty, and facility self-check, and calculates the current-year general R&D credit under Article 10 of the Restriction of Special Taxation Act.
Separately verified benefits can then be compared with incremental cost through net present value, ROI, a benefit-cost ratio, simple payback, and an annual break-even target.

From February 1, 2026, the direct recognition framework is the Act on Support for Research and Development of Corporate Research Institutes and its subordinate legislation.
Older guidance may still identify the former Basic Research Promotion and Technology Development Support Act, so the law in force on the filing date matters.
The official legal, Korea Industrial Technology Association, and National Tax Service sources used here were checked on August 8, 2026.

Minimum dedicated-researcher thresholds in 2026

Article 6 of the Enforcement Decree sets a different minimum for each enterprise status and recognition route.
The Korean statutory classifications matter: a small enterprise and a medium enterprise in this table are subdivisions within the SME framework, while a mid-sized enterprise is a separate legal category.
Confirm the classification date, founding date, transition date, and any special status before selecting a route.

Meeting the numerical minimum does not establish recognition.
The filing also needs evidence of employment status, individual education or professional eligibility, exclusive R&D duties, organizational assignment, an independent research space, equipment, and qualifying research activity.
The green readiness result in the calculator is a planning self-check, not a decision by the Ministry of Science and ICT or its delegated recognition body.

Three non-headcount gates must be evidenced

Individual qualification

Check each dedicated researcher against the education, professional licence, or experience standards in Article 2 of the Enforcement Rule.
Some routes for an SME can recognize particular associate-degree and experience combinations, and industrial-design staff have their own relevant standards.
A job title containing the word researcher does not by itself make the employee eligible.

Dedicated R&D duty

A dedicated researcher must conduct research and development continuously without also performing sales, production, purchasing, or general management work.
The organization chart, appointment record, job description, and actual day-to-day work should tell the same story.
Counting a person who regularly moves between research and production can create recognition and post-recognition compliance risk.

Independent facility

The organization needs an independent research space, research equipment, and supporting facilities suitable for its R&D activity.
Any exception allowing a partitioned small research area must be checked against the space and site facts.
Placing desks somewhere inside a general business site does not automatically satisfy the facility requirement.

The calculator requires all three boxes plus the headcount minimum before recognition-linked benefits enter the cash-flow result.
A failed gate does not erase the separately displayed potential tax credit calculation; it prevents an unready recognition plan from treating that amount as realized project value.
This conservative separation makes an unresolved eligibility condition visible instead of hiding it inside a high ROI.

The official recognition fee is KRW 0, but the operating model is not free

The official Corporate Research Institute and Dedicated R&D Department Recognition Management System states that recognition carries no fee or separate official charge.
The calculator therefore shows an official application fee of KRW 0 and does not invent a statutory filing fee.
A fee quoted by an outside adviser is consideration under an optional service contract rather than money payable to the government for recognition.

Real setup cost can still include partitions or relocation for an independent laboratory, incremental rent, research equipment and furniture, security and safety work, internal documentation time, and optional advisory support.
Lab notebooks, separate project and tax accounting, researcher training, change reporting, safety management, and continued evidence maintenance can create recurring annual cost.
Use actual quotations and internal budgets rather than a generic market package because the recognition body does not publish a required setup price.

The correct decision baseline is the business without the new recognition project.
If equipment, staff, or rent would be incurred in either case, include only the amount that changes because of the institute plan.
Counting a common cost as incremental understates ROI, while omitting a genuine replacement hire or lost operating capacity overstates it.

Added personnel cost

Annual gross salary equals planned added researchers multiplied by monthly gross salary and twelve months.
Annual personnel cost then applies the employer on-cost rate for employer insurance contributions, benefits, and deliberately grouped recurring support cost.
When an existing employee moves into a dedicated role, the true incremental cost can be a replacement employee or foregone operating work rather than the transferred salary in full.

Setup and recurring cost

Annual incremental cost combines added personnel cost and annual fixed operating cost.
Nominal total cost adds the one-time setup amount to annual incremental cost multiplied by the selected number of years.
Present-value cost discounts each year-end recurring amount, so it differs from the undiscounted nominal total whenever the discount rate is positive.

Model the general R&D tax credit as generated, usable, and deferred amounts

Article 10 of the Restriction of Special Taxation Act provides current-year and incremental methods for general research and human-resources development expense.
This establishment model deliberately uses only the current-year method so that it can estimate one transparent and conservative credit effect without asking for four years of historical expenditure.
The dedicated Korean R&D Tax Credit Calculator remains the appropriate tool for comparing the current-year and incremental methods, new-growth and original technology, national strategic technology, and detailed histories.

Years 4–5 after SME graduation15%Verify the tax graduation year and transitional status
Mid-sized enterprise8%Confirm the tax-law definition
Other enterpriseUp to 2%Use half of the eligible-expense-to-revenue ratio, capped at 2%

Eligible expense must be incremental and tax-qualified

The input is not total accounting R&D expense and it is not automatically equal to added payroll.
Enter the net amount reviewed under Annex 6 of the Enforcement Decree that creates a new credit effect compared with the no-institute baseline.
Remove expenditure funded by government contributions and non-qualifying production, sales, ordinary quality control, routine improvement, and other excluded activity.
If the entered eligible base exceeds annual incremental project cost, the calculator allows the scenario but warns that a credit already available without the institute may have been counted twice.

Generated credit is not the same as current cash saving

Multiplying eligible expense by the applicable rate produces a potential generated credit, not an automatic cash refund.
Current-year use can be limited by corporate tax liability, minimum tax, sequencing with other reductions and credits, and the final filed facts.
Enter only the usable capacity reviewed for that tax year, and the model takes the smaller of generated credit and that capacity as the expected current tax saving.
Article 144 can permit eligible unused credit to be carried forward for ten years, but the timing and use are uncertain, so the deferred amount is disclosed and excluded from NPV and ROI.

Enter other benefits only after tracing eligibility and value

Recognition can be relevant to public support programmes, technical workforce arrangements, financing review, procurement, and other business opportunities, but the recognition certificate does not guarantee selection or payment.
Use the annual-other-benefit and one-time-benefit fields only after identifying the specific programme or transaction, its current eligibility rules, the amount attributable to recognition, and the expected cash-flow date.
Leave an unresolved opportunity outside the base case and show it in a separately documented upside scenario.

For a grant, count the amount expected to remain available after matching funds, excluded expenditure, tax treatment, reporting cost, and any cost already included elsewhere in the model.
For added sales or procurement, use contribution after materials, outsourcing, platform charges, commissions, fulfilment, and other variable costs rather than gross contract revenue.
For financing, use the interest or guarantee-fee difference on an expected outstanding balance rather than entering the loan principal as a benefit.

A benefit should also be incremental to the recognition project.
If the business would win the same grant, order, or financing terms without the institute, the common amount belongs in neither side of the decision model.
Keep the source notice, calculation sheet, probability assumption, and owner responsible for refreshing each benefit so that management can audit the result later.

Good evidence for a base case

  • A current programme notice and a documented eligibility review.
  • A tax workpaper separating eligible expense and usable credit capacity.
  • A customer or tender pipeline converted to probability-weighted contribution.
  • A signed financing term sheet or institution-specific rate quotation.

Weak evidence to keep outside the base case

  • A marketing list describing every possible institute benefit.
  • The full face value of a grant before selection and matching cost.
  • Gross revenue without variable cost or probability adjustment.
  • The full generated tax credit without current usable capacity.

Step-by-step calculator workflow

  1. Confirm enterprise size, founding date, venture status, and any small-to-medium transition date, then select the recognition route that can be documented.
    Do not select the lowest threshold merely because it creates a better result.
  2. Enter current people only when their qualification and dedicated role are already supported, then add planned qualified hires or transfers.
    The model costs every planned added researcher even when the plan exceeds the statutory minimum.
  3. Complete the qualification, dedicated-duty, and facility boxes only after reviewing the relevant evidence.
    Any unchecked box makes the self-check unready and prevents recognition-linked benefits from entering project cash flow.
  4. Enter gross monthly salary, employer on-cost, one-time setup cost, and annual fixed operation cost from the actual staffing and facility plan.
    Remove spending common to both the institute and no-institute alternatives.
  5. Choose the tax-law company class separately from the recognition route.
    The two classifications should not be linked automatically because they arise under different legal tests and dates.
  6. Enter revenue where required, incremental Annex 6 eligible general R&D expense, and a current-year usable credit capacity supported by a tax review.
    Check the generated, usable, deferred, and cash-flow tax amounts separately.
  7. Enter only separately verified annual and one-time benefits, then choose a one-to-ten-year horizon and a discount rate from zero to fifty percent.
    Save a conservative case with lower benefit and usable credit before relying on the base result.
  8. Review readiness, annual incremental cost, annual net benefit, NPV, ROI, simple payback, and the annual non-tax benefit needed for break-even.
    Record the assumptions and their owners so that the model can be refreshed when law, staff, or programme facts change.

How NPV, ROI, and simple payback are constructed

Readiness benefit gate

The potential generated tax credit is calculated for information even when the readiness self-check fails.
The tax saving used in cash flow, other annual benefit, and one-time benefit are all set to zero until headcount, qualification, dedicated duty, and facility are checked.
Costs remain in the model because the company can incur preparation and staffing cost even when recognition has not yet been secured.

Present value and ROI

The model assumes level annual incremental cost and benefit at the end of each selected year.
It sums the discount factors from year one through the horizon, adds setup cost at time zero, and adds any recognized one-time benefit at time zero.
NPV equals present-value benefit minus present-value cost, ROI divides NPV by present-value cost, and the benefit-cost ratio divides present-value benefit by present-value cost.
ROI and the ratio are unavailable when present-value cost is zero because a finite percentage would be misleading.

Simple payback and break-even

Simple payback first subtracts recognized one-time benefit from setup cost, then divides the remaining amount by positive annual net benefit and converts the result to months.
It is unavailable when recurring annual benefit does not exceed recurring annual cost.
The annual break-even result solves for the level annual total benefit that makes NPV zero, then subtracts expected usable tax credit to show the remaining annual non-tax benefit required.
Payback is undiscounted, while the break-even annual benefit uses the selected discount rate.

Worked three-year example

Consider a small enterprise within three years of founding that has one qualified dedicated researcher and plans to add one more.
With monthly gross salary of KRW 4 million and a 25% employer on-cost, added annual personnel cost is KRW 60 million.
Assume KRW 10 million of one-time setup cost, no separate annual fixed operation cost, KRW 48 million of incremental eligible general R&D expense, and sufficient tax capacity to use the full SME credit of KRW 12 million.
If separately verified annual contribution is KRW 68 million, annual total benefit is KRW 80 million and annual net benefit is KRW 20 million.

Annual incremental costKRW 60,000,000Added researcher payroll including employer on-cost
Annual total benefitKRW 80,000,000Usable tax credit plus separately verified annual benefit

Net present valueKRW 50,000,000Present-value benefit less present-value cost
ROI26.32%NPV divided by present-value cost
Simple payback6 monthsSetup cost divided by annual net benefit

If the facility box is cleared while every financial input remains the same, recognized benefit falls to zero, present-value cost remains KRW 190 million, and NPV becomes negative KRW 190 million.
The result does not claim that the benefit can never arise; it says that an unresolved recognition prerequisite should not be treated as a completed cash-flow benefit.
Restoring the facility only after the space and evidence are ready makes the transition in the model explainable to management and advisers.

Practical scenarios for different organizations

  • An early software company can compare a two-person institute under the three-year small-enterprise rule with a one-person dedicated department, including the different staffing burden and any support that truly depends on institute status.
  • A small manufacturer can test whether hiring the third qualified researcher creates enough usable tax and operating value to offset payroll, laboratory space, and recurring evidence maintenance.
  • A business that recently moved from small to medium enterprise can model both the temporary three-person threshold and the five-person requirement after the one-year transition period, avoiding a plan that works for only a few months.
  • A mid-sized enterprise facing a seven-person minimum can avoid pretending that the tax credit alone justifies the project and can document contribution from real tenders, support programmes, technical capability, and avoided outsourcing.
  • A business already claiming an R&D credit can subtract the no-institute credit first and enter only the additional eligible base attributable to the new organizational and spending decision.
  • A board or investment committee can lower usable tax capacity, remove uncertain support, increase on-cost, and raise the discount rate to see whether NPV remains positive under a conservative case.
  • An overseas research operation can use the five-person staffing reference but should leave Korean tax benefit at zero until territorial eligibility and allocation of qualifying cost have been separately reviewed.

Frequently asked questions

Does the Korean government charge a recognition application fee

The official recognition management system states that recognition carries no fee or separate official charge, so the statutory application fee in the calculator is KRW 0.
Space, equipment, internal preparation, and optional consulting remain real business costs and should be entered from actual quotations and budgets.

Is the minimum headcount enough for official recognition

No.
Individual eligibility, dedicated duties, independent space, equipment, qualifying R&D activity, organization records, and filing evidence must also satisfy the rules.
The calculator provides a self-check and cannot replace review by the recognition body.

Is every won of researcher salary eligible for the R&D tax credit

No salary becomes eligible merely because the employee works near a research institute.
Verify dedicated-researcher and department conditions, qualifying R&D activity, Annex 6 cost categories, government-funded amounts, and excluded activities.
That is why the staffing-cost input and tax-eligible-expense input are separate.

Why can generated credit exceed current-year tax saving

The statutory rate calculates a potential credit before the actual corporate-tax liability, minimum tax, and ordering of other reliefs and credits are applied.
Article 144 can allow an eligible unused amount to carry forward for ten years, but the future use date is uncertain.
The calculator therefore includes only the user-verified current capacity in cash flow and reports the difference separately.

Can a business start with a dedicated R&D department

The one-person dedicated-department route can reduce the initial staffing threshold and may suit an early organization.
The support scope is not necessarily identical to institute status, and a later transition needs its own staff, facility, and change-reporting preparation.
Compare the two routes using benefits that have been checked for the exact organizational form.

Why are recognition class and tax company class separate

The staffing threshold and the tax-credit rate arise under different statutes, definitions, and measurement dates.
An automatic mapping could silently apply the wrong rate during an enterprise-size transition or after SME graduation.
Confirm each classification independently and keep the supporting date in the model file.

Input controls that improve decision quality

Prevent benefit overstatement

  • Remove tax credit that would be available without the institute.
  • Convert sales to probability-weighted contribution rather than gross revenue.
  • Use current-year tax capacity instead of the full generated credit.
  • Enter a grant only after its route, selection assumptions, and matching cost are documented.
  • Do not give the same support item both a tax and other-benefit label.

Prevent cost distortion

  • Use the replacement or opportunity cost of transferring an existing employee.
  • Remove facility and equipment spending already planned in both alternatives.
  • Include recurring evidence, accounting, safety, and change-reporting work.
  • Keep official recognition fee at KRW 0 and label optional consulting accurately.
  • Test the post-transition staffing level, not only a temporary lower threshold.

Use at least a base case and a conservative case.
The conservative case can increase salary and on-cost, delay or remove unconfirmed benefits, reduce tax capacity, and raise the discount rate.
A project that remains acceptable after those changes is easier to defend than one whose positive NPV depends on every optimistic input arriving immediately.

Official sources and Korea-specific limitation

The calculator uses the official sources below for the recognition framework, staffing and facility standards, tax rates, carryforward boundary, and eligible-cost context.
Law, enterprise classification, programme budgets, and filing facts can change, so use the current source on the recognition and tax filing dates.

Korea-specific planning disclaimer

This calculator applies Korean recognition and tax concepts and is not a global laboratory-registration model.
It does not determine enterprise status, official recognition, researcher eligibility, qualifying expenditure, taxable income, minimum tax, credit ordering, grant selection, procurement success, or the eventual use of a carried-forward credit.
Obtain current recognition, legal, tax, accounting, employment, and programme advice for the actual business and filing period.

Preserve the evidence behind every input

Keep the enterprise-classification date, qualification records, duty assignments, facility drawings, equipment list, Annex 6 tax reconciliation, usable-credit workpaper, benefit source, and scenario owner with the result.
Refreshing those inputs when staffing, law, or support facts change turns the model from a one-time certification estimate into a durable R&D organization decision record.
