The $500 Ladder

Primary sources. Published arithmetic. No courses.

Every Sunday, one thing $500 of starting capital, held in renminbi, can actually become in China, checked against its own statutes, regulators and prices, with the arithmetic to $5,000 a month shown.

China · This week's $500 idea · Pattern break

China's 0.25% scrap-seller tax is a prepayment that stops matching at ¥1,800,000.

国家税务总局公告2026年第12号 第一条, effective 1 July 2026, cuts the reverse-invoicing charge to "年销售额（不含增值税）不超过60万元的部分减按0.25%预缴经营所得个人所得税" [0.25% prepaid on the portion of annual sales up to ¥600,000]. That is not a rate. It is the bottom bracket of the 经营所得 table (5%) multiplied by the 5% 应税所得率 the tax bureau applies when a seller has no cost invoices — and ¥600,000 is simply ¥30,000 ÷ 5%, the top of that bracket. The replication is exact to ¥1,800,000 of sales and then fails, because the next bracket is 20%.

The $500 Ladder — China Sunday, 18 October 2026 Edition 005

The money first. Starting capital is ¥3,361.00 [$500 USD] and the target is ¥33,610 a month [about $5,000 USD], ¥403,320 a year, struck at the China Foreign Exchange Trade System's central parity of 6.7220 published 16 October 2026. This week's route is to become a 自然人报废产品出售者 — a natural person selling scrap into the formal recycling chain under 反向开票, where the buyer writes your invoice, files your VAT and remits your income tax prepayment. You register nothing. You file once a year.

That machinery comes from 国家税务总局公告2024年第5号. 第二条 puts the qualification burden entirely on the buyer: a 资源回收企业 may only reverse-invoice if it holds a 危险废物经营许可证, a 报废机动车回收拆解企业资质认定证书, or has completed 再生资源回收经营者备案 with the commerce department. 第十四条 makes that buyer prepay your tax and file your returns. The seller's only statutory duty is 第十一部分 of the 上海市税务局 reading: "出售者需要在次年3月31日前自行向经营管理所在地主管税务机关办理经营所得汇算清缴" [the seller must file its own annual business-income reconciliation by 31 March of the following year].

Most coverage stops at the headline rate. The arithmetic underneath is public and nobody quotes it. 上海市税务局's own worked example runs it in full: 李某 sells ¥700,000 across two recyclers, prepays ¥2,000, and at the annual reconciliation the bureau computes "（40＋30）×5%×10%－0.15＝0.2万元" [(400,000 + 300,000) × 5% × 10% − ¥1,500 = ¥2,000] and concludes "汇算清缴无需退补税" [no refund or top-up is due]. Prepayment equals liability — because 0.25% is 5% of 5%, and 0.5% is 10% of 5%. The two published rates are the first two rows of 个人所得税法's 经营所得 table, scaled by a deemed margin.

Which tells you where it breaks. The 20% bracket opens at ¥90,000 of assessed income, so at ¥1,800,000 of sales the true marginal charge becomes 1% and the prepayment stays at 0.5%. Run the full allowance that 公告2024年第5号 第一条 permits — ¥5,000,000 in any rolling twelve months, counted across every recycler who invoices you — and you will have prepaid ¥23,500 against a bill of ¥39,500. The 31 March filing is a ¥16,000 demand, 68.09% more than you handed over during the year.

The non-consensus reading is that the rate was never the concession. The 5% 应税所得率 is — it is a ceiling on assessed profit, not an estimate of it, so every point of real margin above five is outside the assessment entirely. And it is generous against the industry it sits in. 格林美股份有限公司 (002340), whose 2025 annual report filed to 巨潮资讯网 on 22 April 2026 names 许开华 as 公司负责人, booked ¥564,691,137.32 of 报废汽车综合利用 revenue against ¥548,753,838.64 of cost: a gross margin of 2.82%. The state deems the doorstep collector earns 5% on scrap; the ¥37.1 billion listed company buying it earns 2.82% gross on the same material. Meanwhile 财政部 税务总局公告2021年第40号 第一条 offers that company 简易计税 at 3% of sales — which on that line exceeds its entire gross profit by ¥1,003,435.44.

So the binding constraint is not capital and never was. It is the ¥5,000,000 personal ceiling, which converts the question "how much can I sell" into "what margin do I hold", and 公告2007年第8号 第九条 — the recycler must record "出售人的姓名、住址、身份证号码" — is what makes the ceiling attach to a person rather than a business. At the cap, VAT of ¥50,000 and income tax of ¥39,500 leave ¥403,320 reachable only above a 9.8564% gross margin. Below that number there is no volume that gets you to $5,000 a month, because there is no volume left to buy.

0 100 200 300 500 600 700 0 1 2 3 4 5 Annual sales, CNY million Net income per year, CNY thousand 15% margin 12% margin 9% margin Target 403,320/yr = 33,610/mo = $5,000 5,000,000 ceiling, 12 months VAT cliff at 1.2m: 1% on everything 1.8m: 20% bracket opens 15% crosses at 3,021,692 · 12% at 3,928,200 · 9% stops 42,820 short at the wall Minimum margin that clears the target inside the ceiling: 9.8564%
Net = margin × sales − VAT − income tax. VAT is nil while monthly sales stay under ¥100,000 and 1% of all sales above it, which is why each line steps down ¥12,000 at ¥1,200,000 a year rather than bending. Income tax is 5% of sales assessed, then the 经营所得 brackets: 5% to ¥30,000 of assessed income (sales ¥600,000), 10% less ¥1,500 to ¥90,000 (sales ¥1,800,000), 20% less ¥10,500 above. So the 15% line reads 0.13 × sales + 10,500 past the second kink and meets ¥403,320 at (403,320 − 10,500) ÷ 0.13 = ¥3,021,692; the 12% line at ÷ 0.10 = ¥3,928,200; the 9% line would need ÷ 0.07 = ¥5,611,714, past the ceiling, and stops at 0.07 × 5,000,000 + 10,500 = ¥360,500. Solving 5,000,000m − 50,000 − 39,500 = 403,320 gives the minimum margin, 9.8564%.

9.8564% is the margin below which the ceiling makes $5,000 a month impossible

Target ¥33,610 × 12 = ¥403,320. At the ¥5,000,000 ceiling, VAT at 1% is ¥50,000 and income tax is ¥39,500, so gross profit must be 403,320 + 89,500 = ¥492,820 and the margin 492,820 ÷ 5,000,000 = 9.8564%; total tax is 1.79% of sales. Above the ¥1,800,000 kink net = (m − 0.02) × sales + 10,500, so 15% clears the target at (403,320 − 10,500) ÷ 0.13 = ¥3,021,692, 12% at ÷ 0.10 = ¥3,928,200, and 9% reaches only 0.07 × 5,000,000 + 10,500 = ¥360,500. Separately, 3% of 格林美's 报废汽车综合利用 revenue is 0.03 × 564,691,137.32 = ¥16,940,734.12 against a gross profit of 564,691,137.32 − 548,753,838.64 = ¥15,937,298.68, an excess of ¥1,003,435.44.

A buyer without it pays you in cash and leaves you outside the regime entirely.

  3. Insist on 三流合一, which is what makes ¥3,361 enough to run on

    公告2026年第12号 第一条 halves the prepayment to 0.25% only for "三流合一反向开票", described by 上海市税务局 as "支付即开票、开票即缴税、缴税即入库". The invoice is issued at the moment of payment on the platform rail, so the float returns the same day instead of sitting in a receivable. The stake is not the year's capital; it is one settlement cycle, and the policy shortens the cycle to minutes.

    ¥3,361 is a cycle, not a year

  4. Understand that the missing cost invoice is the concession

    个人所得税法 第六条 第（三）项 taxes gross receipts less costs — but households do not issue invoices for scrap, which is precisely why 反向开票 exists. With no cost evidence the authority applies the 5% 应税所得率 the 上海市税务局 example uses. That is a ceiling on assessed profit, not an estimate of it. Every point of real margin above five sits outside the assessment.

    assessed income = 5% × sales, whatever you actually make

  5. Treat ¥100,000 a month as a cliff, not a threshold

    公告2024年第5号 第十三条 keeps the 小规模纳税人 reliefs available: no VAT below ¥100,000 of monthly sales, otherwise 3% 征收率 reduced to 1%. Crossing it does not tax the excess — it taxes the whole month. Annualised, the step from ¥1,200,000 to ¥1,200,001 of sales costs ¥12,000. Either stay under ¥100,000 every month or go past it decisively; the middle is the only bad place to be.

    ¥1,200,000 → ¥1,200,001 costs ¥12,000 a year

  6. Mark ¥1,800,000, after which 31 March becomes a bill

    Assessed income reaches ¥90,000 at ¥1,800,000 of sales and the bracket turns 20%, so the real charge becomes 1% while the prepayment stays 0.5%. Below that line the two numbers are identical and the reconciliation is a formality; above it the shortfall is 0.5% × sales − ¥9,000, reaching ¥16,000 at the ceiling. Set it aside monthly, because 公告2024年第5号 ties your buyer's ability to keep invoicing you to your having filed.

    shortfall = 0.005 × sales − 9,000, from ¥1,800,000 up

  7. Solve for margin, because the ceiling has already solved for volume

    ¥5,000,000 in twelve months is the most anyone will ever reverse-invoice you, and 商务部令2007年第8号 第九条 ties it to your 身份证号码, so it cannot be split across buyers or names. At that volume ¥403,320 needs a 9.8564% gross margin. A 12% margin gets there on ¥3,928,200 of sales; 15% on ¥3,021,692. Nine per cent never gets there. The route is a margin problem wearing a volume problem's clothes.

    5,000,000m − 50,000 − 39,500 = 403,320 → m = 9.8564%
