- Since 1 January 2023, a qualifying resident enterprise may deduct an extra 100% of its eligible R&D expenses on top of the actual amount — a “super-deduction” that has been made a permanent, economy-wide rule (财政部 税务总局公告2023年第7号).
自2023年1月1日起，符合条件的居民企业可在据实扣除基础上再按研发投入的100%加计扣除——此项”加计扣除”已成为面向全行业的长期制度安排（财政部 税务总局公告2023年第7号）。- Capitalised R&D is amortised at 200% of cost; integrated-circuit and industrial-machine-tool firms enjoy an even higher 120% super-deduction through 31 December 2027.
资本化的研发费用按成本200%摊销；集成电路与工业母机企业在2027年12月31日前享受更高的120%加计扣除比例。- Foreign-invested enterprises are fully eligible — the rate no longer varies by “high-tech SME” or “manufacturing” status; only the six negative-list industries and non-resident enterprises are excluded.
外商投资企业完全具备资格——比例不再区分”科技型中小企业”或”制造业”；仅负面清单六类行业及非居民企业被排除。- The benefit is claimed on a self-assessment basis and can be enjoyed as early as the July and October prepayments, not only at annual settlement (国家税务总局 财政部公告2023年第11号).
优惠采取自行判别、申报享受方式，并可在7月、10月预缴申报时提前享受，而非仅在汇算清缴时（国家税务总局 财政部公告2023年第11号）。- R&D auxiliary accounts (辅助账) are mandatory; expenses must be separately pooled from production costs, with entrusted and overseas R&D subject to the 80% and two-thirds caps.
研发辅助账为必备；研发费用须与生产费用分别核算，委托研发与境外研发分别适用80%计入及不超过总额三分之二的上限。- FIEs should treat R&D super-deduction as a measurable target — project authenticity, accurate pooling, and complete documentation are the focus of 2026 local-tax follow-up under the golden-tax data environment.
外商投资企业应将研发费用加计扣除视为可衡量目标——项目真实、归集准确、资料齐全是2026年”金税”数据环境下地方税务机关后续管理的重点。
The R&D Super-Deduction for Foreign-Invested Enterprises (2026) | 外商投资企业研发费用加计扣除优惠（2026）
Why this matters now
For a foreign-invested enterprise running any genuine R&D in China — a wholly owned R&D centre, a joint-venture manufacturer with a local engineering team, or a shared-service unit developing software — the R&D super-deduction is the single largest, most broadly available tax saving on the books. It is not a sector-specific perk reserved for “national champions”; since 2023 it applies uniformly to every audit-based resident enterprise that can document its R&D. For an FIE, that means the China subsidiary — a Chinese tax resident — can slash its taxable base on locally incurred innovation spend, while the offshore parent (a non-resident) cannot claim it directly.
The policy has matured into a stable, long-term instrument. The headline rate was lifted from 75% to 100% and, by a State Council decision of 24 March 2023, locked in as a permanent arrangement rather than a sunsetting stimulus. Local tax bureaus in 2026 continue to publish step-by-step guidance, and the data-cross-check environment (“Golden Tax Phase IV”) has made clean project documentation the dividing line between a smooth claim and a recovered benefit.
The core benefit and its legal basis
Under the *Announcement on Further Improving the Pre-tax Super-Deduction for R&D Expenses* (Ministry of Finance and SAT Announcement 2023 No. 7), effective 1 January 2023:
- R&D expenses actually incurred that do not form an intangible asset are, after the actual deduction, additionally deducted at 100% of the actual amount.
- R&D expenses that do form an intangible asset are amortised at 200% of the asset’s cost.
Announcement 2023 No. 7 repealed the earlier tiered rates (75% for general firms, 100% only for manufacturing and tech SMEs) and made the 100% rate a uniform, economy-wide, long-term rule. The State Taxation Administration’s accompanying interpretation describes this as stabilising business expectations and unifying the treatment of all enterprises. The measure sits within the framework of Cai Shui [2015] No. 119 (the master R&D-deduction notice) and Cai Shui [2018] No. 64 (overseas entrusted R&D).
Who qualifies — and who does not
Eligibility is intentionally broad. A resident enterprise that keeps sound accounting, is collected on an audit basis (查账征收), and can accurately pool its R&D expenses qualifies — regardless of ownership. A WFOE or Sino-foreign JV with real R&D is on the same footing as a domestic firm.
Two exclusions matter for an FIE group:
- Negative-list industries. Six sectors are excluded wholesale: tobacco manufacturing; accommodation and catering; wholesale and retail; real estate; leasing and business services; and entertainment. A multi-business FIE is excluded only if a negative-list line exceeds 50% of its relevant revenue base.
- Non-resident enterprises. The offshore parent is not a Chinese tax resident and cannot claim the super-deduction on its own books; the benefit accrues only to the China resident subsidiary that incurs the R&D.
For integrated-circuit and industrial-machine-tool enterprises, the rate steps up further: a 120% super-deduction (and 220% amortisation) applies for the period 1 January 2023 to 31 December 2027 under Announcement 2023 No. 44 — but only for firms on the relevant state-issued catalogue.
When you can claim: prepayment timing
A key practical improvement is timing. Under SAT and Ministry of Finance Announcement 2023 No. 11, an enterprise may enjoy the super-deduction during the July (second-quarter) prepayment and the October (third-quarter) prepayment, as well as at the annual CIT settlement. This lets an FIE shorten the gap between incurring R&D cost and realising the tax saving, improving cash flow, rather than waiting until the following year’s reconciliation. The claim remains self-assessed: the enterprise judges eligibility, computes the additional deduction in the return, and keeps the supporting files.
Documentation: the R&D auxiliary account
The super-deduction is claimed without prior approval, but the taxpayer must be able to prove it. The linchpin is the R&D auxiliary account (辅助账) — a project-by-project ledger that pools each deductible expense category. Indispensable requirements:
- Separate accounting. R&D and production/operating expenses must be split; where they cannot be clearly allocated, the deduction is disallowed.
- Project-by-project pooling. Multiple concurrent projects are pooled separately; a unified collection-and-allocation approach is permitted for centrally run, high-cost group R&D.
- Entrusted R&D. Expenses paid to an external party are counted at 80% of actual cost. Where the contractor is a related party, it must supply a breakdown of its R&D spend.
- Overseas entrusted R&D. Under Cai Shui [2018] No. 64, overseas entrusted R&D is included at 80% of actual cost, but the includable overseas portion may not exceed two-thirds of the total deductible R&D expenses.
- Creative-design activities for innovative products may also qualify under the prescribed rules.
Local 2026 guidance (e.g. Henan and Guizhou tax bureaus) stresses standardising R&D project management, clearly distinguishing production from R&D, accurately pooling labour, direct inputs, and depreciation, and keeping the project plan, stage records, and results report as retained evidence.
Stacking with other FIE incentives
The super-deduction is not mutually exclusive with other preferences and commonly stacks:
- High-new-tech enterprise (HNTE) 15% rate. A recognised HNTE still computes its taxable income after the 100% super-deduction, then applies the 15% rate — the deduction and the rate compound.
- Foreign R&D centre import VAT refund. Qualifying foreign R&D centres can also claim a full VAT refund on domestically purchased equipment (Announcement 2023 No. 41), a complementary, not overlapping, saving.
- Pre-tax deduction for foreign talent. R&D-intensive FIEs often combine the super-deduction with preferential individual-income treatment for key foreign technical staff.
A practical compliance checklist for FIE groups
- Confirm residency and accounting basis. Ensure the China entity is an audit-based resident enterprise; the offshore parent cannot claim.
- Establish the auxiliary account before R&D begins, with a project立项 document, budget, and staffing plan.
- Segregate R&D from production in the ERP and payroll so labour and overhead allocation is defensible.
- Document entrusted/overseas R&D with contracts, the 80% treatment, and — for related parties — the contractor’s cost breakdown; cap overseas at two-thirds.
- Claim early at the July or October prepayment to free cash flow.
- Retain the full file (project plan, ledgers, results, contracts) for the statutory period; expect data cross-checks on project and expense authenticity.
Common pitfalls
Frequent failure points are: no auxiliary account at all; mixing routine process optimisation or customisation with qualifying R&D; allocating non-R&D overhead into the pool; missing the 80%/two-thirds limits on entrusted and overseas R&D; and claiming for a negative-list-line business above the 50% threshold. In the 2026 enforcement climate, authorities probe whether the activity is genuinely innovative (clear novel goal, systematic organisation, uncertain outcome) and whether costs are real and traceable. Treating the super-deduction as a disciplined, year-round documentation programme — not a year-end adjustment — protects the saving.

外商投资企业研发费用加计扣除优惠（2026）/ The R&D Super-Deduction for Foreign-Invested Enterprises (2026)
为何当下重要
对任何在中国开展真实研发的外商投资企业——外商独资研发中心、拥有本地工程团队的合资制造厂，或开发软件的共享服务中心——研发费用加计扣除都是账面上最大、最普惠的节税工具。它不是专属于”国家队”的行业特惠；自2023年起，它统一适用于任何能够规范归集研发的查账征收居民企业。对外商投资企业而言，这意味着作为中国税收居民的中国子公司可以就本地发生的创新投入大幅缩减税基，而境外母公司（非居民）则无法直接享受。
该政策已 maturation 为稳定、长期的工具。加计比例由75%提高至100%，并经2023年3月24日国务院常务会议决定，作为长期制度性安排固定下来，而非阶段性刺激。地方税务机关在2026年持续发布分步指引，而”金税四期”数据比对环境使得干净的研发项目文档成为顺利享受与被追缴的分界线。
核心优惠与法律基础
依据《关于进一步完善研发费用税前加计扣除政策的公告》（财政部 税务总局公告2023年第7号，自2023年1月1日起施行）：
- 研发活动中实际发生、未形成无形资产的研发费用，在据实扣除基础上，再按实际发生额的 100% 加计扣除。
- 形成无形资产的，按无形资产成本的 200% 税前摊销。
2023年第7号公告废止了此前的阶梯比例（一般企业75%、仅制造业与科技型中小企业100%），将100%比例确立为全行业、长期统一的规则。国家税务总局的配套解读称此举在于稳定企业预期、统一各类企业待遇。该措施置于财税〔2015〕119号（研发加计扣除主文件）与财税〔2018〕64号（委托境外研发）框架之内。
谁有资格——谁没有
资格条件有意放宽。保持会计核算健全、实行查账征收、并能准确归集研发费用的居民企业即具备资格——与股权性质无关。拥有真实研发的外商独资企业或中外合资企业与本土企业处于同等地位。
对外资集团而言，两类排除须注意：
- 负面清单行业。 六类行业整体排除：烟草制造业；住宿和餐饮业；批发和零售业；房地产业；租赁和商务服务业；娱乐业。多业经营的外商投资企业仅当某负面清单行业收入超过其相关收入基数50%时才被排除。
- 非居民企业。 境外母公司不是中国税收居民，无法在其自身账簿上享受加计扣除；优惠仅归属于发生研发的中国居民子公司。
对集成电路与工业母机企业，比例进一步提高：依据2023年第44号公告，在2023年1月1日至2027年12月31日期间适用 120% 加计扣除（及220%摊销）——但仅限列入相关国家清单的企业。
何时享受：预缴时点
一项关键的实操改进是时点。依据国家税务总局 财政部公告2023年第11号，企业可在 7月（第二季度）预缴 与 10月（第三季度）预缴 以及年度汇算清缴时享受加计扣除。这使外商投资企业缩短研发投入与实现节税之间的时滞、改善现金流，而无须等到次年汇算清缴。享受仍为自行判别：企业判断资格，在申报中计算加计额，并留存备查资料。
文档：研发辅助账
加计扣除无需事前审批，但纳税人须能证明。关键在于 研发辅助账——按研发项目设立的、归集各可加计费用类别的台账。不可或缺的要求：
- 分别核算。 研发费用与生产、经营费用须分开；划分不清的，不得加计扣除。
- 分项目归集。 多项研发活动分别归集；对技术要求高、投入大的集团集中研发，可按权利义务一致、费用收益配比原则分摊。
- 委托研发。 委托外部机构或个人发生的费用按实际发生额 80% 计入委托方研发费用；受托方为关联方的，须提供研发项目费用支出明细。
- 委托境外研发。 依财税〔2018〕64号，委托境外研发费用按80%计入，但计入的境外部分不得超过可加计研发费用总额的 三分之二。
- 创意设计活动 为获得创新性产品而发生的相关费用，可按规定加计扣除。
2026年地方指引（如河南、贵州税务机关）强调规范研发项目管理、清晰区分生产与研发、准确归集人员人工、直接投入与折旧，并留存项目计划书、阶段记录与成果报告作为备查证据。
与其他外资优惠叠加
加计扣除与其他优惠并非互斥，常可叠加：
- 高新技术企业15%税率。 已认定的高新技术企业在先按100%加计扣除计算应纳税所得额后，再适用15%税率——扣除与税率形成复合效应。
- 外资研发中心国产设备增值税全额退还。 符合条件外资研发中心还可就采购国产设备申请增值税全额退还（2023年第41号公告），属互补而非重叠的节税。
- 外籍人才税前扣除。 研发密集的外商投资企业常将加计扣除与关键外籍技术人员的个人所得税优惠并用。
外资集团实操清单
- 确认居民身份与征收方式。 确保中国实体为查账征收居民企业；境外母公司不可享受。
- 在研发启动前建立辅助账，附项目立项书、预算与人员计划。
- 在ERP与薪酬中隔离研发与生产，使人工与制造费用分摊可辩护。
- 文档化委托/境外研发，备合同、80%处理，以及关联方下受托方费用明细；境外部分不超过三分之二。
- 尽早享受，于7月或10月预缴时释放现金流。
- 留存完整档案（立项书、台账、成果、合同）至法定年限；预期将就项目与费用真实性开展数据比对。
常见误区
常见失分点包括：完全没有辅助账；将日常工艺优化或客制化混入合格研发；把非研发费用分摊进归集池；遗漏委托与境外研发的80%/三分之二上限；以及对超过50%门槛的负面清单行业企业申报。在2026年执法环境下，税务机关重点核查活动是否真正具有创新性（明确创新目标、系统组织、结果不确定）以及费用是否真实可追溯。将加计扣除视为一项有纪律、贯穿全年的文档化项目——而非年末调整——方能守住这项节税。
