A post goes viral saying Japan will cover up to half of your Claude subscription, and everyone has the same reaction:
Wait, the government will pay half my AI bill?
It sounds like a dream. The Claude charge on your monthly card statement suddenly gets a fancy new title: "eligible subsidy expense."
But this is not a cashback deal for AI subscriptions.
Japan's 2026 Digitalization and AI Introduction Subsidy helps small and medium-sized businesses and small business owners pay for part of a registered IT tool they bring in to work more efficiently. In the standard track, the subsidy usually covers up to 1/2 of the cost. Software purchases and cloud fees can count for up to 2 years.
Read only that part, and yes, it looks like Claude at half price.
But there are gatekeepers at the door. More than one.
1. "I barely make any money" isn't the real problem
The key point: earning very little and not having the paperwork are two different problems.
If you apply as a sole proprietor in 2026, you need ID, and in principle also:
- a recent income tax payment certificate, "No. 1" or "No. 2"
- your tax return for 2025
- a blue-form financial statement, or an income and expense statement if you file the simple white form
The official materials don't set a simple rule like "you must make at least X yen a year."
So "I'm barely earning anything yet" doesn't end the story on its own.
The real problem is this: if you didn't file taxes as a business last year, the documents that prove you run a business simply don't exist.
So it's not:
not earning → rejected
It's:
no business tax return last year → you can't hand in the papers the 2026 application asks for
As a conversation, it goes something like this:
Subsidy: "Using AI? We might cover half." You: "I am!" Subsidy: "Great. Last year's business tax return, please." You: "My business wasn't really a thing yet." Subsidy: "Then go back to last year and grow it." You: "Is there a time machine track?" Subsidy: "No."
That's usually the moment the viral post turns into real-life paperwork.
2. Having a gBizID doesn't get you through on its own
You need a gBizID Prime account, and you also have to make the "SECURITY ACTION" declaration.
But gBizID isn't a master pass that proves you're a business that's allowed to apply.
Think of it this way:
gBizID = the login key for government online services
not
gBizID = a spell that summons your past business history
Even with gBizID ready, if you don't have the tax return and the blue-form statement or income and expense statement, a sole proprietor's paperwork still isn't complete.
You have the key. You just don't have the building pass.
So close.
3. Claude can qualify, but not every Claude plan is "half off"
In 2026 you can find several Claude plans listed as registered IT tools.
So the viral post isn't completely made up.
What matters, though, is the registered entry, not the product name.
To get the subsidy, you generally have to buy a registered IT tool through a registered IT support vendor. Even for the same Claude, the conditions depend on the plan, the registered price, the business process it covers, and the vendor.
You can't add up what you've already paid Anthropic directly and say:
"I paid 120,000 yen for Claude this year. Send me 60,000."
As a rule, the contract, order, and payment for the subsidized purchase come after the grant is approved.
So it's not a points-back program.
You don't bring receipts afterward. You apply first, then buy through the official route.
4. One person on Claude Pro may not even reach the minimum
In the standard track, for 1 or more business processes, the subsidy must be at least 50,000 yen and under 1,500,000 yen.
If you're one person on a fairly cheap plan like Claude Pro, depending on the registered price, even 2 years of fees at a 1/2 rate may not reach the 50,000 yen minimum.
So these are two different sentences:
"Claude Pro is on the list of registered IT tools." and "If I sign up for Claude Pro alone, I'll get the subsidy."
On social media, they merge in a second into:
THE GREAT CLAUDE HALF-PRICE FESTIVAL
The program is not hosting any festival.
5. "Sole proprietors are fine" is half true and half risky
Sole proprietors can qualify.
Even if you have a regular job and run a business on the side, being an employee doesn't automatically rule you out.
But the program doesn't pay for AI you use for hobbies or your private life.
You need to be running an actual business, and the tool has to be used to make that business more productive.
Skip that, and the speedrun
employee ↓ uses Claude ↓ calls themselves a sole proprietor ↓ half off
doesn't work.
Government paperwork isn't a game where a real business spawns the moment you type in a job title.
6. Three typical situations
A. You already run a business and filed a tax return last year
Get your gBizID Prime, SECURITY ACTION, and tax documents ready, then check the registered IT tool and the IT support vendor.
This is the normal path to consider applying.
B. You started a side business this year but didn't file as a business last year
This is where most people get stuck.
Even if you're really working now, you probably can't provide the 2025 business documents the 2026 application asks for.
"I run a business now" and "I can hand in last year's required documents" are two different things.
C. You use AI, but only for personal stuff
That's outside what the program is for.
Watching Netflix one day "for work research" doesn't make it a Netflix subsidy. Same here: just using AI doesn't make you eligible for a business subsidy.
7. The checklist that actually matters
When you see the post, the first question isn't "Is Claude eligible?"
Go in this order:
- Do you count as a small or medium-sized business, small business owner, or sole proprietor under the program?
- Can you submit your 2025 tax return?
- Can you submit a blue-form financial statement or an income and expense statement?
- Can you get income tax payment certificate "No. 1" or "No. 2"?
- Do you have gBizID Prime?
- Have you made the SECURITY ACTION declaration?
- Is the Claude plan you want listed as a registered IT tool?
- Can you apply with that entry alone, or do you need to combine it with another tool?
- Does your subsidy reach the minimum amount?
- Have you avoided signing, ordering, or paying before the grant is approved?
Only after all that are you standing at the door of "maybe it's half off."
An ad needs one line.
A subsidy needs ten.
That's government for you.
8. Bottom line: it's not "I don't earn enough," it's "I don't have last year's paperwork"
It's genuinely interesting that AI subscriptions can qualify, and the program has real value for small businesses.
But it doesn't automatically refund half of a personal subscription you already pay for.
If you've only just started a side gig or your own business, check whether you have last year's tax return and business documents before worrying about how much you earn now.
Ending with "Well, I don't make much money" is a little off.
More precisely:
You don't have last year's business save file yet.
Even in the age of AI, subsidies don't hand out top-tier gear the moment you start a new game.
Start by making that save file.
