The only zero-tax structure in PRC law is the one that forbids adding value.
增值税法 第二十四条, in force since 1 January 2026, exempts "农业生产者销售的自产农产品" [agricultural products produced and sold by the producer] with no ceiling of any kind, and 财税〔2004〕30号 第一条 leaves the same income "暂不征收个人所得税" [individual income tax not levied for the time being]. 财政部 税务总局公告2026年第10号 then states where it stops: "用外购农产品生产、加工的初级农产品，不属于本项目免征增值税的范围" [primary products made or processed from bought-in produce fall outside this exemption]. Processing is the disqualifying act.
The money question first. Starting capital here is ¥3,366.50 [$500 USD] and the target is ¥33,665 a month [about $5,000 USD], ¥403,980 a year, struck at the China Foreign Exchange Trade System's central parity of 6.7330 published 9 October 2026. Nothing on this week's route costs ¥3,366.50 to begin. There is no company to form, no filing, no licence and no tax registration — 电子商务法 第十条 excuses 个人销售自产农副产品 from 市场主体登记 outright, which makes this the one category of online seller in China that lawfully operates with no registration at all. The whole stake is growing medium.
What is unusual is not the exemption. It is that the exemption has no size limit while every other small-business relief in the system does. 增值税法 第九条 caps the small-scale class at ¥5,000,000 of annual sales; 公告2026年第10号 sets the 起征点 at ¥100,000 of monthly sales and the reduced rate at 1%; last week's 综试区 concession stops working the moment the owner takes a dividend. The grower's exemption is attached to the physical act — 财税字〔1995〕52号 defines the exempt seller as one "直接从事植物的种植、收割和动物的饲养、捕捞的单位和个人" [units and individuals directly engaged in planting and harvesting plants or raising and catching animals] — so it cannot be bought, sold, structured into or aged out of. It can only be performed.
And the party on the other side of the trade is not the farmer. 上海雪榕生物科技股份有限公司 (300511), whose chairman and legal representative 蒋智 took the chair on 21 November 2025, grew and sold 401,485.64 tonnes of mushrooms in 2025 — about 1,099,961 kg a day — and paid no VAT on a kilogram of it. Its 2025 annual report, filed to 巨潮资讯网 on 28 April 2026, shows ¥1,987,614,708.05 of revenue and ¥29,793,998.17 of net profit attributable to shareholders: a net margin of 1.4990%. The largest beneficiary of the exemption in the country keeps a hundred and fiftieth of a yuan per yuan sold. Wherever a crop can be industrialised, the exemption has already been competed into the shelf price and handed to the shopper.
That is the non-consensus reading. 自产农产品免税 is written as a subsidy to producers and functions as a subsidy to buyers, and the proof is in the price series rather than the statute: 农业农村部市场与信息化司 put the weekly average of its 28 monitored vegetables at ¥4.36 a kilogram in week 40 of 2026, down 3.3% on the week and 12.3% on the year, with 平菇 down 7.9% in seven days. 雪榕's own accounts imply a realisation of ¥4.8962/kg against a cost of ¥4.2744/kg. Put those two numbers together and a person clearing ¥33,665 a month at wholesale prices needs 13,109 kg a day. The exemption is only still on the table for someone who never visits the wholesale market — and that is precisely the seller 电子商务法 第十条 pre-cleared.
The evidence
10 findingsAn exemption with no ceiling, in a law whose every other relief has one
第二十四条 lists nine exempt items, the first being "农业生产者销售的自产农产品" [agricultural products produced and sold by the producer]. The article attaches no revenue limit, no headcount test and no time limit. 第九条, by contrast, defines the small-scale class as taxpayers whose "年应征增值税销售额未超过五百万元" [annual VAT taxable sales do not exceed ¥5,000,000], and 第十一条 fixes the simplified rate at 3%. The same statute repealed 增值税暂行条例 on the day it took effect. 国家税务总局政策法规库.
The boundary is drawn at the purchase, not at the size
The bridging announcement that carried the old VAT reliefs into the new law restates the exemption and then fences it: "纳税人销售外购的初级农产品，以及用外购农产品生产、加工的初级农产品，不属于本项目免征增值税的范围，应当按照规定缴纳增值税。" [A taxpayer's sales of bought-in primary agricultural products, and of primary products produced or processed from bought-in produce, fall outside this exemption and are taxed as prescribed.] The same announcement keeps the small-scale 起征点 at "月销售额10万元" and the rate "依照3%征收率减按1%征收率" to 31 December 2027 — both irrelevant to an exempt grower. 国家税务总局政策法规库.
And the income tax has been suspended for twenty-two years
"农村税费改革试点期间，取消农业特产税、减征或免征农业税后，对个人或个体户从事种植业、养殖业、饲养业、捕捞业，且经营项目属于农业税（包括农业特产税）、牧业税征税范围的，其取得的'四业'所得暂不征收个人所得税。" [During the rural tax-and-fee reform pilot, following abolition of the agricultural specialty tax and reduction or exemption of agricultural tax, individual income tax is not levied for the time being on the "four industries" income of individuals and individual businesses engaged in planting, aquaculture, animal raising and fishing.] 第三条 sets it running from 1 January 2004; it has not been withdrawn. 国家税务总局上海市税务局.
The exempt person is defined by the act, and the exempt list includes fungi
The annex defines the exempt seller as "直接从事植物的种植、收割和动物的饲养、捕捞的单位和个人" [units and individuals directly engaged in the planting and harvesting of plants and the raising and catching of animals], and 上海市税务局 adds that produce bought from others and then processed or resold is outside it. Under 蔬菜 the note reads: "本货物的征税范围包括各种蔬菜、菌类植物和少数可作副食的木本植物" [the scope covers all vegetables, fungal plants, and a small number of woody plants usable as side dishes]. Under 其他植物 it lists "树苗、花卉、植物种子、植物叶子、草". 国家税务总局政策法规库 · 上海市税务局.
The one online seller in China that needs no registration
"电子商务经营者应当依法办理市场主体登记。但是，个人销售自产农副产品、家庭手工业产品，个人利用自己的技能从事依法无须取得许可的便民劳务活动和零星小额交易活动，以及依照法律、行政法规不需要进行登记的除外。" [E-commerce operators shall register as market entities. Excepted are: individuals selling self-produced farm and sideline products or household handicrafts; individuals using their own skills for convenience services requiring no licence; sporadic small-value transactions; and those not required to register under law or administrative regulation.] Self-produced produce is named first. 国家互联网信息办公室.
The largest beneficiary of the exemption keeps 1.4990% of revenue
Revenue ¥1,987,614,708.05, down 8.09%; net profit attributable to shareholders ¥29,793,998.17, up 104.83%. Production 401,395.05 tonnes, sales 401,485.64 tonnes. By product: 金针菇 revenue ¥1,410,111,409.84 against cost ¥1,229,931,193.85, a 12.78% gross margin; 真姬菇 ¥394,053,927.46 against ¥345,471,140.36, 12.33%; 杏鲍菇 ¥82,461,229.63; other mushrooms ¥79,122,262.89. Total mushroom cost ¥1,716,115,309.17. 巨潮资讯网.
Wholesale vegetables are ¥4.36 a kilogram and falling 12.3% a year
"重点监测的28种蔬菜批发市场周均价每公斤4.36元，环比跌3.3%，同比低12.3%。" [The weekly average wholesale price of the 28 closely monitored vegetables was ¥4.36 per kilogram, down 3.3% week on week and 12.3% lower than a year earlier.] 平菇 fell 7.9% in the same week. The 农产品批发价格200指数 stood at 115.13 against a 2015 base of 100, down 1.11 points on the week and 5.53 points on the year. 中国农业农村信息网.
¥4.8962 realised, ¥4.2744 cost, and a 13,109 kg/day wall at wholesale
Mushroom revenue ¥1,410,111,409.84 + 394,053,927.46 + 82,461,229.63 + 79,122,262.89 = ¥1,965,748,829.82 on 401,485.64 t = 401,485,640 kg, so realisation = ¥4.8962/kg and cost = 1,716,115,309.17 ÷ 401,485,640 = ¥4.2744/kg, a 12.6992% gross margin across the whole book. At the week 40 wholesale average of ¥4.36 the spread is ¥0.0856/kg, so clearing ¥33,665 a month needs 33,665 ÷ (30 × 0.0856) = 13,109 kg a day. 雪榕 sells 401,485,640 ÷ 365 = 1,099,961 kg a day and nets 29,793,998.17 ÷ 1,987,614,708.05 = 1.4990%.
¥112,216.67 exempt, ¥126,683.57 as a shop, ¥141,212.25 as last week's export company
Target ¥33,665 a month. Exempt grower: VAT nil, income tax nil, so net = 0.30R and R = ¥112,216.67, tax ¥0. 个体工商户 reselling bought-in goods: 1% VAT above the ¥100,000 起征点 and 经营所得 tax halved under 公告2023年第12号, after the ¥60,000 基本减除费用 — net = 0.30R − 0.01R − tax, solving to R = ¥126,683.57 and ¥4,340.07 of tax a month. 综试区 export company paying a dividend (edition 003): net = 0.80 × R(0.30 − 0.002) → R = ¥141,212.25, tax ¥8,698.67. The exemption is worth 11.42% less revenue than a shop and 20.53% less than the celebrated export structure.
The gate in Shanghai is a certificate, not a tax form
第五十条: "上市销售的肉类产品应当附有检疫合格证明；上市销售的其他食用农产品应当附有产地证明、检测合格证明。" [Meat offered for sale must carry a quarantine certificate; other edible agricultural products offered for sale must carry a certificate of origin and a certificate of passing inspection.] 第六十二条 第二款: "区人民政府可以根据需要，依法划定临时区域（点）和固定时段供食品摊贩经营，并向社会公布。" [District governments may designate temporary areas or points and fixed hours for food vendors, and publish them.] The tax is zero; the paperwork that actually binds is municipal and physical. 上海市人民政府.
The ladder
From $500 to $5,000 a month · ¥3,346 → ¥33,461财税字〔1995〕52号 defines the exempt seller as one "直接从事植物的种植、收割" and 公告2026年第10号 puts bought-in produce outside the exemption in terms. There is no version of this route that runs on a supplier. Everything that makes it unusual — no ceiling, no registration, no tax — follows from the fact that the benefit cannot be transferred, which is also why nobody has arbitraged it away.

Grow it yourself, because the exemption is attached to the hands
财税字〔1995〕52号 defines the exempt seller as one "直接从事植物的种植、收割" and 公告2026年第10号 puts bought-in produce outside the exemption in terms. There is no version of this route that runs on a supplier. Everything that makes it unusual — no ceiling, no registration, no tax — follows from the fact that the benefit cannot be transferred, which is also why nobody has arbitraged it away.
"直接从事植物的种植、收割" · the defining phrase -
Register nothing, and check that again before paying anyone to register something
电子商务法 第十条 names 个人销售自产农副产品 as the first exception to 市场主体登记. No 营业执照, no 个体工商户, no tax registration, and therefore no annual filing, no accountant and no 代办 fee. The registration industry that sells China market entry has nothing to sell here, which is roughly why you have not read this anywhere.
电子商务法 第十条 · exception one of four -
Do not process, package into a manufactured good, or buy to resell
This is the whole edition. 公告2026年第10号: "用外购农产品生产、加工的初级农产品，不属于本项目免征增值税的范围". The standard advice — add value, build a brand, move up the chain — describes the exact set of acts that cancels the exemption and moves you to ordinary VAT and ordinary 经营所得 tax at 5–35%. Wash it, trim it, sell it.
processing → 增值税 + 经营所得税 · growing → neither -
Ignore every threshold in the system, including the ones that bound last week's route
增值税法 第九条's ¥5,000,000 small-scale ceiling, the ¥100,000 monthly 起征点 and the 1% rate in 公告2026年第10号, the ¥3,000,000 small-profit cap, the 20% dividend charge in 个人所得税法 第三条 — none of them touch an exempt grower, because none of them are tests the exemption uses. At a 30% margin the exempt route clears ¥33,665 on 20.53% less revenue than the 综试区 export company of edition 003.
¥112,216.67 vs ¥126,683.57 vs ¥141,212.25 a month -
Never sell into the wholesale market, where the exemption has already been spent
农业农村部's 28-vegetable weekly average is ¥4.36/kg, 12.3% below a year ago, and 雪榕's accounts imply a ¥4.2744/kg cost. The spread is 8.56 fen. Clearing ¥33,665 a month on it takes 13,109 kg a day. 雪榕 does eighty-four times that volume and keeps 1.4990% of revenue. Any crop with a wholesale price series is a crop where the exemption already belongs to the buyer.
33,665 ÷ (30 × 0.0856) = 13,109 kg/day -
Pick the volume you can actually sell direct, then read the price off the curve
p = 4.2744 + 33,665 ÷ (30q). Fifty kilos a day needs ¥26.72/kg; a hundred needs ¥15.50; two hundred needs ¥9.89. Those are the only three decisions on this ladder, and they are decisions about a delivery round and a customer list, not about tax. Everything above ¥4.36 is a channel you built; nothing above ¥4.36 exists at the wholesale gate.
50 kg/day → ¥26.72 · 100 → ¥15.50 · 200 → ¥9.89 -
Budget for the certificate, which is the only gate that is real
上海市食品安全条例 第五十条 requires a 产地证明 and a 检测合格证明 on every edible agricultural product offered for sale, and 第六十二条 confines 食品摊贩 to the 临时区域（点）and hours a district government publishes. The tax authority asks nothing of this business; the market regulator asks for paper and a pitch. Plan the route around the district notice, not the tax code.
