Is "sugar dating" (or "papa katsu") a side job? Is it taxable income? [Conclusion]

To start with,Income earned through "sugar dating" may be considered a side job under the company's employment regulations.

To put it simply, income earned through "sugar dating" is highly likely to be considered a side job under your company's employment regulations, and will be subject to miscellaneous income or gift tax under tax law.

The definition of a side job can be organized from the following three perspectives:

• Company employment regulations define side jobs as any activity that generates income outside of one's main job.
• Taxable under tax law: Income subject to miscellaneous income or gift tax.
• Social perception: Activities widely recognized as side jobs on social media, etc.

For company employees, if you have income exceeding 20 yen per year from sources other than your main job, you are required to file a tax return.

The allowances received through "sugar dating" are no exception.

By correctly understanding the tax treatment, you can file your tax return properly and eliminate the risk of penalties for failure to file.

Three reasons why "sugar dating" is chosen as a side hustle | Includes PATOLO's unique market rate data

Currently, with the spread of sugar daddy apps, more and more women are starting sugar daddy relationships as a side job.

"My main job isn't enough to make ends meet, but I don't have the time or energy to take on multiple part-time jobs."

For those facing such problems, sugar dating might seem like an attractive option.

Here, we'll introduce three main reasons why "sugar dating" (or "papa katsu") is chosen as a side job.

Easy to earn a high income in a short amount of time

The biggest appeal of "sugar dating" is the potential to earn a high income in a short amount of time.

While the average hourly wage for a typical part-time job is around 1,000 to 1,500 yen, the going rate for "sugar dating" (papakatsu) is 10,000 yen or more for a single meal or date.

According to PATOLO's independent research, the desired amount of allowance varies widely depending on the region and age group, with the median in Tokyo being approximately 64,340 yen and in Okinawa Prefecture approximately 79,167 yen.

Since you can earn in 1-2 hours what you would earn working 8 hours at a part-time job, it's quite time-efficient.

It offers more flexibility in terms of time compared to part-time jobs or other side jobs.

Unlike regular part-time jobs, sugar dating doesn't involve shifts or fixed working hours.

If you can coordinate with the other person's dad's schedule, you can make effective use of your free time, whether it's during the day or at night.

If you engage in "sugar dating" as a side job, you can work flexibly, such as in the evenings after work on weekdays and during the day on weekends and holidays. This makes it easy to start even for those with busy main jobs or irregular schedules.

Expectations of networking with people you wouldn't normally meet and experiencing something out of the ordinary.

Many of the men you can meet through "sugar dating" are wealthy individuals such as business owners and professionals, with whom you wouldn't normally have contact in your everyday life.

Gaining knowledge from experienced dads and discovering new worlds are significant benefits beyond the financial compensation.

The opportunity to visit high-end restaurants you wouldn't normally go to and to have extraordinary experiences is also a major draw.

Understanding these three reasons will allow you to calmly determine whether sugar dating is truly the right side hustle for you.

Four risks of using "sugar dating" as a side hustle: Pitfalls you'll regret not knowing about

While there are benefits to having a side job through "sugar dating,"Of course, there are risks involved.

Here, we'll honestly share the risks you should be aware of before you start.

Make sure you understand everything thoroughly beforehand so you don't regret it later.

Loss of social credibility due to identity being revealed

If your sugar daddy relationship is discovered by your friends or family,This could lead to a loss of trust.

If your identity is revealed at work, in the worst-case scenario, you could be fired or forced to resign.

Once social credibility is lost, it's not easy to regain it.

You should always be aware of the risk of your identity being revealed.

Fraud and other financial troubles

In Papa life,Financial troubles are not uncommon.

There are cases where people say they'll give you money but don't pay, or they say they forgot their wallet or will pay later and then just run away.

In cases where a woman has received large sums of money or gifts from her "sugar daddy," she may face problems when the relationship ends, such as being pressured to "return" them.

To avoid financial troubles,It is important to thoroughly select a partner and confirm their conditions beforehand.

Mental exhaustion and numbness to financial sense

Trying to force myself to get along with my dad, who is much older than me,It can be mentally exhausting.

While there's much to learn from conversations with a knowledgeable and experienced dad, it's not easy to keep up with discussions about worlds you're unfamiliar with.

Furthermore, by earning a high income in a short amount of time,It deviates from the general sense of moneyThere is also that risk.

Simulation of the amount you will lose due to back taxes and late payment penalties for unpaid taxes.

If you fail to file your tax return and pay your taxes, you may be contacted by the tax office later.

In addition to the original tax, penalties such as a non-filing penalty tax and late payment penalties will be incurred.

Based on PATOLO's independent survey of the median cost in urban areas (approximately 64,340 yen per visit in Tokyo), a simulation shows that you would lose the following amounts.

Item	Amount of money
Allowance (per payment, median in Tokyo)	About 64,340 yen
Annual income if you meet 5 times a month	About 386 yen
Income after expense deduction (assuming 20%)	About 309 yen
Original income tax (miscellaneous income, 10% tax rate)	About 21 yen
Penalty for failure to file tax return (15% for amounts up to 50 yen, 20% for amounts exceeding 50 yen up to 300 yen)	About 4 yen
Late payment penalty (maximum annual rate of 8.7% for a one-year delay)	About 1.8 yen
Total amount of additional loss	About 5.8 yen

The penalty tax for failure to file a tax return is levied in stages, depending on the amount of tax payable.

令和6年1月1日以後に法定申告期限を迎える申告については、50万円まで15%、50万円超300万円まで20%、300万円超は25%が加算される仕組みです。

Furthermore, if you file your tax return after receiving notification of a tax audit, the tax rate will increase, and if it is deemed malicious, you may be subject to a heavy penalty tax (35-40%).

Is income from "sugar dating" subject to gift tax or income tax? What are the types of taxes and criteria for determining eligibility?

Money received through "sugar dating" can be subject to either gift tax or income tax (miscellaneous income).

The criterion for judgment is "whether or not it constitutes a contract."

Let's clarify which category your case falls into.

Cases subject to gift tax (gifts and allowances)

If there is no clear contract or service provision relationship with your father, and you receive pocket money or gifts out of goodwill, it will be subject to gift tax.

There is a basic exemption of 1.1 million yen per year for gift tax, so if the total amount of property received during the year from January 1st to December 31st is 1.1 million yen or less, no gift tax will be levied.

Source:National Tax Agency, "No. 4402 Cases in which gift tax applies"

The important point to note is that the determination is based on the total amount received from multiple "sugar daddies."

The tax-free threshold is not "1.1 million yen from one dad," but rather "the total amount from all dads is 1.1 million yen or less."

Cases subject to income tax (miscellaneous income) (periodic and contractual)

If you receive money in a continuous relationship that is close to a contract, such as "meeting X times a month for Y amount of money," it will be subject to income tax.

It is believed that much of the allowance received through "sugar dating" falls under the category of miscellaneous income.

If you are a company employee (salaried worker), you are required to file a tax return if your income other than your main job's salary exceeds 20 yen per year.

If you are a full-time employee (student or unemployed) and your only source of income is "sugar dating," you will need to file a tax return if your annual income exceeds 48 yen (basic deduction).

Miscellaneous income is calculated by subtracting necessary expenses from revenue.

Expenses directly related to the activity, such as transportation costs and beauty treatments, are deductible as business expenses.

Check the table to see what threshold requires you to file a tax return in your specific case.

Case	Declaration required line	税金 types	Filing deadline
Side jobs for company employees	Annual income exceeding 20 yen	Income tax (miscellaneous income)	February 16th to March 15th of the following year
Full-time (student/unemployed)	Annual income exceeding 48 yen	Income tax (miscellaneous income)	February 16th to March 15th of the following year
One-time gift (no contractual element)	Over 110 million yen per year	Gift tax	February 1th to March 15th of the following year
Combining part-time work within the dependent allowance limit	Salary income of 103 yen + α	Income tax + loss of dependent status	February 16th to March 15th of the following year

Since income from "sugar dating" is not considered salary income, calculating these income thresholds is somewhat complex.

It is recommended to check with the tax office or a tax accountant for specific guidelines.

[Exclusive Data] Tax Amount Simulation by Annual Income | Estimated using PATOLO Market Data

Based on PATOLO's own research on allowance data, we simulated annual income and tax amounts based on activity frequency.

Since compensation varies greatly by region, the figures here are based on the average level in urban areas (approximately 50,000 to 60,000 yen per session).

Number of activities per month	Annual income (allowances only)	Expenses (20% deduction)	Taxable income	Income tax (5-10% tax rate)
1 times a month (12 times a year)	Approximately 60 to 72 yen	Approximately 12 to 14 yen	Approximately 48 to 58 yen	¥0 to ¥29,000 (amount exceeding the basic deduction)
3 times a month (36 times a year)	Approximately 180 to 216 yen	Approximately 36 to 43 yen	Approximately 144 to 173 yen	Approximately 72,000 to 100,000 yen
5 times a month (60 times a year)	Approximately 300 to 360 yen	Approximately 60 to 72 yen	Approximately 240 to 288 yen	Approximately 14 to 20 yen (10% tax rate range)

If you engage in activities at a pace of three or more times a month, you will incur taxes of over 70,000 yen per year.

Neglecting expense management and filing tax returns can lead to significant losses due to back taxes.

Now that you understand the types and amounts of taxes, let's look at "how they actually find out."

Why do you get caught? 5 reasons why your sugar daddy side hustle gets discovered by your company and the tax office.

If you are doing "sugar dating" as a side job,There are several ways in which this can be discovered by your company or the tax office.

Knowing in advance where you might get caught is the first step in taking preventative measures.

Here, we will explain four typical cases.

My resident tax notice changed and my company found out.

The most common way for it to be discovered by the company is,This is a scenario where the company's accounting department notices something is wrong when they see the amount of resident tax on the notice.

Since the amount of resident tax is determined by the previous year's income, if your income from a side job increases, your resident tax will also increase.

For company employees, resident tax is generally deducted from their salary,The accounting staff finds it suspicious that the local tax is high relative to the employee's salary.

In companies that prohibit side jobs, reports are often submitted from the accounting department to HR or general affairs, which is how side jobs are often discovered.

It can be exposed through social media posts or by a third party's tip-off.

The high-end restaurants visited through sugar dating and the brand-name items received,Sometimes people get caught because they accidentally post about it on social media.

If your clothing choices or spending habits suddenly become extravagant, it may raise suspicion among those around you.

Furthermore, it's not uncommon for sugar dating to be discovered by colleagues or acquaintances at work, leading to them reporting the situation to the authorities.

Failure to file tax returns and "claiming expenses on the father's side" can lead to being caught (counter-investigation and My Number system).

Failure to file a tax return is highly likely to be discovered by the tax authorities.

There are mainly three ways in which you might get caught.

• Expense reporting and counter-investigation on the father's side
• Submission of payment records to the tax office
• Linking bank accounts using My Number (Social Security Number)

If the "sugar daddy" is a business owner or entrepreneur, he may be able to claim expenses related to sugar dating as business expenses.

If the tax office investigates the father, the investigation will also extend to the woman.

Furthermore, if the father has submitted a payment statement to the tax office, the woman's information may also be included.

In recent years, the linking of My Number (Japan's social security and tax number) to bank accounts has progressed, and a system is in place that allows the tax office to check for any suspicious deposit history.

The higher a father's income, the more likely he is to be subject to a tax audit.

When an investigation is launched into the father's life, it often results in the woman being implicated as well.

It can be revealed through bank account, PayPay, and e-money transaction history.

Frequent large deposits into an account under a personal name may be considered suspicious and could trigger an investigation by the tax authorities.

Even if you pay in cash, a record will ultimately be kept when the money is deposited into a bank account or charged to an electronic money service like PayPay.

Electronic money transaction histories can also be subject to investigation by the tax authorities, so you can't say that "cash is safe."

Even if you think you can keep your money hidden, remember that the flow of money can be traced through various channels.

The tax audit of the dating app company revealed the truth.

In recent years, tax authorities have been intensifying their tax investigations into companies that operate dating apps and paid dating apps.

If the operating company is audited by the tax authorities, there is a possibility that registered user information and transaction history will be shared with the tax authorities. It is dangerous to be overconfident and think, "It's a major app, so it's safe."

Transactions conducted through the app carry the risk of individual female members' tax status being checked later.

[Essential Guide] 4 Practical Strategies to Keep Your Sugar Daddy Side Hustle a Secret

We've covered the risks of sugar dating and how it can get exposed.

Some of you may have thought, "Sugar dating is scary after all,"Taking preventative measures beforehand can reduce the risks.

Here, we will introduce four specific points to be aware of and how to address them.

[Measure 1: Taxes] How to file your tax return | 5 steps for filing miscellaneous income tax return + tax relief for late filing

Income from sugar dating is,Generally, it is declared as miscellaneous income.

In this case, expenses necessary for "sugar dating" can be claimed as business expenses, so it's a good idea to keep track of expenses such as transportation costs, beauty treatments, and clothing costs.

Furthermore, cash or pocket money received on a one-time basis is treated as a gift.If the amount exceeds 110 million yen per year, a gift tax return must be filed..

By filing your taxes correctly, you can avoid the risk of being caught by the tax authorities and the penalties for not filing.

[Preventing your company from finding out] Switch your method of collecting resident tax to "ordinary collection"

Filing your tax return for income earned through "sugar dating" involves the following five steps.

• Step 1: Record your income for the year.
• Step 2: Organize your expenses and keep your receipts.
• Step 3: Prepare your tax return
• Step 4: Submit via e-Tax, mail, or at a tax office counter.
• Step 5: Pay income tax

For Step 1, it's recommended to record your income in Excel or a notebook, noting the transaction date, amount, and payment method.

Step 3, preparing the tax return, is handled by the National Tax Agency.Tax return preparation sectionIt can be calculated automatically.

The submission deadline for Step 4 is from February 16th to March 15th of the following year for income tax purposes.

It's also important to address past undeclared income (retroactive filing for multiple years). You can file tax returns for up to five years retroactively. For example, as of 2026, you would file returns for 2021 through 2025 in order.

Creating them in chronological order, starting with the oldest year, will make the process smoother.

There are two types of late tax returns: "voluntary filing" and "filing after a tax audit," and there is a significant difference in the tax rates between them.

Timing of filing	Tax rate for penalty for failure to file a tax return
File within the legal deadline	0% (no additional tax)
Voluntarily file a late tax return before receiving a tax audit notice.	5%
Filing a tax return after notification of a tax audit or before the audit.	10~15%
Tax return filed after tax audit	15~30%

If you file a tax return voluntarily before receiving a tax audit notice, the penalty tax will only be 5%, so if you're worried about past tax returns, filing a return now is the best course of action.

[Measure ② Expenses] Transportation expenses, beauty expenses, clothing expenses | Items that can be deducted from miscellaneous income

When calculating miscellaneous income, you can deduct expenses directly related to your sugar daddy activities.

Typical expense items are as follows:

• Transportation expenses (train and taxi fares to visit Dad)
• Beauty expenses (part of the cost of hair salons, nail salons, and spa treatments necessary for activities)
• Clothing expenses (cost of purchasing clothes, shoes, and bags for activities)
• Cafe and meal expenses (self-funded portion only)
• Communication expenses (part of the cost of the smartphone used to communicate with Dad)

The important point to remember is that a clear separation between your work life and your personal life is necessary.

For example, since it may not be possible to deduct the entire cost of beauty treatments as a business expense, it is safer to record it as an expense only for the days you are actively working.

Receipts and invoices must be kept for seven years. Taking photos of them with a smartphone app and managing them digitally can reduce the risk of losing them.

Thorough expense management can significantly reduce your actual income tax, and it also allows you to handle tax audits with confidence.

[Countermeasure ③: Preventing your company from finding out] Specific steps to switch to "ordinary collection" of resident tax.

The most important point to prevent your company from finding out is to switch your method of collecting resident tax to "ordinary collection" when filing your tax return.

The procedure for switching is as follows: On the second page of your tax return, in the section titled "Matters concerning resident tax and business tax," check the item "Method of collecting resident tax on income other than salary and public pensions, etc."

If you check the "Pay myself" box here, the notification for resident tax on your side job will be sent to your home address instead of your company address.

If you do nothing, your taxes will be treated as special withholding, and your company will receive a notice of resident tax including your income from your side job.

It's important to note that some municipalities may not allow ordinary collection. Also, there's a small chance that a mistake by the municipality could result in your taxes being mistakenly collected through special collection.

After filing your tax return, be sure to check the "Resident Tax Assessment Notice" that you receive from your local government around May to confirm whether your income from your side job is being collected through ordinary collection.

[Countermeasure ④ Identity exposure and trouble] Thorough management of social media and careful selection of people and locations.

• Prepare contact information (phone number and email address) for your activities.
• They use a nickname during their activities and never reveal their real name.
• I keep my SNS accounts for finding sugar daddies completely separate from my regular SNS accounts.
• The payment will be given in cash (bank account information will not be provided).
• I don't post photos of restaurants or gifts on my regular social media.
• I will not disclose any personally identifiable information such as my real name, workplace, or nearest train station.

There is a non-zero risk of becoming involved in crimes such as fraud, voyeurism, or violence. To protect yourself, be careful when choosing who you meet and where you meet.

Be especially cautious of people who offer particularly high compensation, as they may have scamming or dangerous intentions.

When meeting a dad for the first time, I always avoid private rooms or enclosed spaces and instead meet in a public place where there are other people around.

Summary | Sugar dating as a side hustle is sustainable if you take thorough tax and safety precautions.

While "sugar dating" offers the advantage of earning high income in a short amount of time and working at your own pace, it also comes with risks such as taxes and the possibility of your identity being revealed.

• The type of tax is determined by the contractual nature of the transaction (gift tax for amounts exceeding 110 million yen per year / income tax).
• The risk of your company finding out can be largely prevented by switching to ordinary collection of resident tax.
• You can reduce penalties by filing your tax return late by utilizing expenses (transportation costs, beauty treatments, clothing expenses).
