Isekai "Mana Surcharge" Skyrockets. National Tax Agency Rules "Slime Dissolving Is Not Eligible for Medical Deduction"

On the 19th, as the tax filing deadline approaches at tax offices across the country, anguished cries can be heard leaking from special service windows. “I saved the world — so why won’t they let me expense my potions?!” Behind the isekai reincarnation boom, two issues are becoming increasingly severe: the soaring “mana surcharge” added at the moment of reincarnation, and the brutal tax processing that awaits returnees.

According to the Ministry of Land, Infrastructure, Transport and Tourism and the All-Japan Reincarnation Truck Association, the mana (magical energy) market rate required to open an interdimensional gate is currently at historic highs. Geopolitical risks in Middle Eastern spirit zones and growing concerns about global mana resource depletion are cited as causes, and the “mana surcharge” automatically deducted upon truck collision has reached an average of 300,000 yen one way. As a result, reincarnators who run out of funds and cannot afford proper starter equipment — only to suffer serious injuries fighting slimes in the beginner village — are a never-ending problem.

What has driven reincarnators even further into despair is a new directive issued by the National Tax Agency this month. Dragon burns and slime acid dissolving injuries sustained in other worlds have been explicitly defined as “arising not from business-necessary travel, but from personal hobbies and entertainment (voluntary travel).” As a consequence, the massive quantities of medicinal herbs consumed and healing magic treatments received on-site will, as a rule, be denied as eligible medical expense deductions.

At tax filing venues in Tokyo, an eerie scene is unfolding as recently returned former heroes collapse to their knees one after another. To a man claiming “the receipt is burned because I fought a fire demon,” a counter clerk coldly replied, “The revenue stamp and addressee cannot be verified, rendering it invalid. Please request a reissue.” Additionally, cases are piling up where purchases of “Hi-Elixirs” are summarily dismissed on the grounds that “the therapeutic effect is excessive for ordinary injury treatment and qualifies as anti-aging for cosmetic purposes.”

A tax accountant at Paladin Joint Accounting Firm, which specializes in reincarnation law, points out: “Since labor standards inspection offices do not exist in other worlds, Demon Lord subjugation is regarded as a ‘freelance project by a sole proprietor (compensation undetermined).’ Special enrollment in workers’ compensation insurance is also unavailable, and under the modern Japanese tax system, it is entirely self-responsibility.” Life-risking quests are, for tax purposes, nothing more than “an extension of an extremely high-risk hobby” — such is the cold bureaucratic wall that stands before them.

More terrifying than the Demon Lord’s curse is the mountain of denied expenses and the delinquent tax that accompanies them. With the hands that once gripped a holy sword, heroes now tremble as they operate tax calculation smartphone apps. They are beginning to realize: no matter how much peace they bring to another world, what is truly invincible in modern society is neither legendary magic nor divine protection, but the unwavering tax collection system.

Stakeholder Comments

• Tax filing counter clerk: “I don’t care if you show me a ‘Guild Certificate’ every day. Do you have your My Number card?”
• Returned former hero: “The tax office is way harder to break through than the Demon Lord’s castle. The receptionist’s physical resistance and logic resistance are off the charts.”
• Reincarnation truck driver: “With the surcharge going up, lately even if I hit someone, I can only send them to ’nearby other worlds (somewhere around Gunma).’”
• Herb shop owner (otherworld native): “They suddenly started asking me for ‘invoice-compliant receipts’ recently. Parchment isn’t good enough?”
• Tax accountant specializing in other worlds: “Whether healing magic counts as ‘medical treatment’ or ‘spiritual comfort’ is where opinions split with the tax office. The lack of precedent is what makes this painful.”
• Slime: “I apologize for dissolving them, but I never thought Japan’s National Tax Agency would classify our acid as ‘injury from a hobby.’ A country of self-responsibility is scary, puru.”
• Charred receipt: “I protected him from the fire breath, but I was completely reduced to ash by the tax office’s gaze.”
• Ministry of Health, Labour and Welfare representative: “Since no written outsourcing contract was exchanged for the Demon Lord subjugation, it does not qualify as an occupational injury.”
• Life insurance company review department: “Multiple deaths due to ‘death rewind’ may result in us withholding insurance payouts from a moral risk perspective.”
• Ordinary taxpayer: “The person next to me was arguing about ‘depreciation of Excalibur,’ and suddenly my own filing mistake felt insignificant.”
