Late at night at his desk, Mr. Sato let out a deep sigh as he compared a mountain of receipts against his bankbook. It had been three years since he started working as a freelance web designer. Fortunately, his annual revenue had grown to nearly 8 million yen, yet the money remaining in hand was far less than expected. The burden of social insurance premiums and income tax felt heavier each year. He continued to spend significant time every month on accounting tasks, leaving him unable to focus on his core design work.
Conclusion: For sole proprietors and freelancers with revenue and profits above a certain level who are struggling with the heavy burden of social insurance premiums and taxes, the "Lowest-Cost Micro-Corporation Package," which allows you to verify tax-saving effects for free before signing a contract, is the ideal solution. Starting from 10,000 yen per month with zero settlement fees, the condition that you do not need to proceed with the contract if the tax benefits do not exceed the accountant's fees provides peace of mind, making it easy to reverse course even for those incorporating for the first time.
The Hidden Burden of Taxes and Social Insurance Premiums for Sole Proprietors

A sole proprietor's take-home pay is not determined simply by subtracting expenses from revenue. In addition to income tax and resident tax, they must bear the full cost of National Health Insurance premiums and National Pension premiums themselves. As revenue grows, the burden of social insurance premiums and income tax increases, strengthening the sensation that "even though I'm earning more, nothing is left in my pocket." Furthermore, time that could be spent securing orders for their core business is eaten up by the rush to maintain books and prepare final tax returns. This is a structural dilemma faced not only by Mr. Sato but by many sole proprietors who exceed a certain revenue threshold.
One option in such cases is establishing a micro-corporation. By forming a corporation and receiving income in the form of executive compensation, sole proprietors may be able to reduce their social insurance premium burden. Of course, the effectiveness varies depending on the nature of the business and income situation. What matters most is being able to verify with concrete figures before signing a contract just how effective this approach would be for one's specific circumstances.
Having heard from a fellow professional that "setting up a micro-corporation helped lower social insurance premiums," Mr. Sato began investigating, albeit with some skepticism.
Service Details and Features of the "Lowest-Cost Micro-Corporation Package"
The "Lowest-Cost Micro-Corporation Package" is a tax advisory service provided by Kikuchi Accounting Office. Its defining feature is comprehensive support covering everything from the establishment of a micro-corporation to ongoing tax advisory services, with a wide range of included offerings.
Main Service Contents
- Support for establishing a micro-corporation
- Tax advisory services (bookkeeping agency, tax return preparation, tax consultations, handling inquiries from tax offices, etc.)
- Consultation support for loans and subsidies
- Nationwide coverage (fully online)
- Free tax-saving simulation prior to contract signing
- Contract available only if projected tax savings exceed the service fees
Of particular note is the opportunity to receive a free tax-saving simulation before signing a contract. Based on your individual income tax return, they can estimate the potential tax savings achieved by incorporating. Furthermore, a unique condition is applied: you can only proceed with the contract if the estimated tax savings exceed the accountant's fees. In other words, this is a rare fee structure that minimizes the risk of being pressured into a contract when cost-effectiveness cannot be demonstrated.
Additionally, since all procedures are completed online, the service is highly accessible for residents in rural areas or individuals who find it difficult to schedule face-to-face meetings. Sato began to think, "In that case, it might be worth listening to their proposal at least once."
You can start the application process by requesting a free quote on the official website.
Fee Comparison: Is the Performance Worth Starting at ¥10,000 per Month?
Tax advisor fees cannot be properly compared without examining not only the monthly rate but also year-end settlement fees and contract terms. The "Cheapest Micro-Corporation Package" advertises a pricing structure starting from ¥10,000 per month with a ¥0 year-end settlement fee. The ability to verify effectiveness through a free simulation prior to contracting is also a crucial factor in measuring cost-performance.
Comparison of Major Tax Advisor Service Fees
| Service Name | Monthly Fee | Year-End Settlement Fee | Free Pre-Contract Simulation | Supported Services |
|---|---|---|---|---|
| Cheapest Micro-Corporation Package | From ¥10,000 | ¥0 | Yes (Contract only if benefits exceed fees) | Incorporation support, bookkeeping agency, tax filing, consulting, tax office liaison, loan/subsidy consulting |
| YFP Clare Tax Corporation | From ¥6,000 (Limited to sole proprietors acting as presidents) | Not disclosed | Not disclosed | Tax accountant support |
| Fairness Tax Office | ¥22,000 | Not disclosed | Not disclosed | Micro-corporation incorporation support, bookkeeping, final account filing |
| Uemura Accounting & Tax Corporation | Not disclosed | Not disclosed | Not disclosed | Micro-corporation advisory |
A ¥0 year-end settlement fee means no lump-sum expenses are incurred separately at the end of the fiscal year, offering the advantage of easier annual cost tracking. Additionally, being able to estimate tax-saving effects before signing a contract helps reduce mismatches where clients feel the results were not as effective as expected after joining. Beyond the fee schedule, whether the pre-contract process is reasonable is a critical decision criterion for those incorporating a company for the first time.
That said, there are low-cost services like YFP Clare starting from ¥6,000 per month, so it is not the absolute cheapest based on numbers alone. However, YFP Clare has conditions limiting it to companies with a single president, so you must confirm whether you qualify. Fairness Tax Office offers the appeal of bundling bookkeeping and final account filing for ¥22,000 per month, but looking solely at monthly fees, it is not necessarily lower than the Cheapest Micro-Corporation Package. Ultimately, the deciding factor in your choice is whether the service can demonstrate your specific tax-saving effects in numerical terms before you sign a contract. Being able to review an estimate before spending money provides peace of mind that lowers the initial barrier to seeking consultation.
Free Tax-Saving Simulations: The Key to Signing Without Regret
For those considering establishing a micro-corporation, the biggest hurdles are often doubts like, "Will this actually save me taxes?" or "Is it worth the fees?" This service proactively addresses these concerns by offering a free tax-saving simulation before you sign any contract.
Here is how it works: First, you request a free estimate through the official website and have them calculate your potential tax savings based on your final tax return. The condition is simple: you only sign the contract if the calculated tax savings exceed the accountant's fees. If the savings fall short of the fees, you can naturally choose not to proceed. This mechanism significantly lowers the barrier to "just hearing them out," even if you currently lack sufficient knowledge.
Mr. Sato also decided to request a free estimate first, with his final tax return in hand. If the results show a clear benefit in numbers, he can sign; if not, he can simply decline. Being able to verify your specific conditions without increasing your own costs provides significant peace of mind for those who do not want to fail during their first attempt at incorporation. The structural strength of this service lies in its ability to help you avoid the risk of signing an expensive advisory contract without adequate knowledge. Since you can get a free estimate and only commit after confirming the benefits, starting with a free estimate is the most logical first step.
Actual Ratings and Key Considerations Based on Reviews
An analysis of ratings across multiple review platforms reveals that opinions on this service generally fall into two categories. On the positive side, many users praise the courteous support and the clarity of explanations provided.
"Even for small-scale businesses, the support is kind and meticulous." (Multiple review sites)
"We have received extensive assistance regarding company establishment. We are very grateful for the clear explanations and advice." (Multiple review sites)
Summarizing the recurring positive themes, the following points are frequently highlighted:
- Pre-contract Tax Saving Verification: The peace of mind gained from being able to verify potential effects via simulation before signing a contract.
- Fee Transparency: A clear pricing structure starting from 10,000 JPY per month.
- Nationwide Coverage: The convenience of a fully online process accessible regardless of location.
- Bookkeeping Services: The benefit of being able to outsource accounting tasks entirely.
On the other hand, there are important considerations to keep in mind. Public information states that contracts cannot be finalized unless the tax savings exceed the service fees. Viewed from another angle, this means that "not everyone is eligible to sign up." Additionally, individuals unfamiliar with the micro-corporation mechanism may find certain aspects complex, and it is essential to understand beforehand that the amount of tax saved varies significantly from person to person.
It should be noted that since the number of reviews is limited, definitive conclusions should be avoided. However, based on the scope of publicly available information, the meticulous support provided to small-scale businesses stands out as a defining feature. Mr. Sato felt that, "At the very least, they seem to explain things in a way that even someone like me with no prior knowledge can understand," which lowered his psychological barrier to requesting a quote.
Who It's Right For (and Who It's Not)
Micro-corporation setup and tax advisory services don't benefit everyone. Checking whether your situation fits beforehand can help you avoid unnecessary consideration.
Ideal Candidates
- Sole proprietors and freelancers with sufficient revenue and profits who feel burdened by income tax and social insurance premiums
- Individuals who want to outsource bookkeeping, accounting, and tax filing to focus on their core business
- Those seeking tax advisory services that can be completed entirely online
- People who want to verify potential tax savings with concrete numbers before signing a contract
Not Recommended For
- Individuals with low revenue and profits, where the cost-effectiveness of incorporating is uncertain
- Those strongly averse to corporate structures and accounting, lacking the capacity to learn while proceeding
It's especially important to emphasize that if your revenue and profits are low, incorporation could actually increase your financial burden. Becoming a corporation doesn't automatically reduce social insurance premiums or tax liabilities; depending on your circumstances, maintenance costs and administrative burdens may outweigh any benefits. That's precisely why it's crucial to use the free simulation before contracting to determine which side you fall on.
The first step is to check your potential tax savings using the free simulation on the official website.
How It Works: From Free Estimate to Starting Tax Advisory Services
The process from application to service initiation can be broken down into four simple steps. Since everything is completed online, there is no need to visit an office in person.
| Step | Description | Key Points |
|---|---|---|
| 1. Request a Free Estimate | Apply via the official website and simulate tax-saving effects based on your final tax return | No offline visit required; completely free of charge |
| 2. Review Tax-Saving Effects | Examine the simulation results to determine if the tax savings exceed the accountant's fees | No obligation to sign a contract if savings do not exceed fees |
| 3. Contract & Micro-Corporation Establishment | Proceed with corporation establishment procedures online | Establishment support makes it easy even for first-timers |
| 4. Tax Advisory Service Begins | Bookkeeping services, tax return preparation, tax consultations, and liaison with tax authorities commence | Entire accounting workload can be delegated |
Mr. Sato felt that applying for the free estimate in Step 1 and simply sending his final tax return could easily be done during breaks from his current job. Since the effectiveness can be verified before signing a contract, the psychological barrier is reduced to merely "listening to what they have to say."
So, What Will Mr. Sato Do? Criteria for Making a Decision When Unsure
Mr. Sato decided to request a free estimate. He does not assume that incorporating will definitely be profitable. However, he reasoned that there is no reason not to try if he can verify the exact amount of tax savings possible for his situation with hard numbers, free of charge, before signing a contract. If the benefits fall short of the professional fees, he simply won't proceed with the contract. Knowing this fact alleviated his anxiety about taking action.
Let's organize the criteria for making a decision when you are unsure.
This service is specifically suited for sole proprietors and freelancers whose sales and profits exceed a certain level and who feel the heavy burden of taxes and social insurance premiums. There are two reasons for this. First, you can verify the potential benefits with a free tax-saving simulation before contracting, and you only proceed with the contract if those benefits exceed the tax accountant's fees. Second, you can start by outsourcing your bookkeeping at a low cost, starting from 10,000 JPY per month with zero year-end settlement fees. These two points create a structure that allows individuals who do not want to fail in their first incorporation to take the next step without significantly increasing their out-of-pocket expenses. Since you can decide after seeing the projected results, you reduce the risk of later regretting that "it wasn't what I expected."
