01What changes to EIS, VCT and BIR take effect from 6 April 2026?+
From 6 April 2026 the company-level investment limits for EIS and VCT are increased so more scaling UK ventures qualify, while the rate of VCT income tax relief is reduced from 30% to 20%. Business Investment Relief (BIR) continues with transitional rules covering pre-6 April 2025 foreign income and gains until 5 April 2028, after which no new BIR claims are permitted from 6 April 2028.
02Are the EIS company investment limits really being raised in April 2026?+
Yes. The Government has legislated higher company-level annual and lifetime EIS and VCT limits from 6 April 2026, intended to support knowledge-intensive and capital-intensive scaling businesses that previously hit the older caps before reaching commercial viability.
03Does SEIS change in April 2026?+
The headline April 2026 changes target EIS, VCT and BIR. SEIS limits (£250,000 company raise, £350,000 gross asset cap, under-3-years trading, 25 employees, £200,000 individual investor cap) remain in place. Founders should still plan SEIS now and EIS afterwards under the new limits.
04Why is VCT income tax relief being reduced to 20%?+
The reduction from 30% to 20% reflects HM Treasury's rebalancing of the VCT regime against rising company-level limits. The CGT exemption on disposal of qualifying VCT shares is preserved, and tax-free dividends from VCTs continue, so VCTs remain investable — but the upfront relief is less generous from 6 April 2026.
05What happens to Business Investment Relief after April 2026?+
BIR continues for qualifying investments made with pre-6 April 2025 foreign income and gains under transitional rules until 5 April 2028. From 6 April 2028 it will no longer be possible to claim BIR on new investments or reinvestments. Investors holding remittance-basis funds should plan deployment well before that sunset.
06Do I need to refile or restructure existing Advance Assurance?+
Existing Advance Assurance is not invalidated by the April 2026 changes. However, companies planning fresh raises after 6 April 2026 should revisit their use-of-funds, risk-to-capital narrative and share class structure to take full advantage of the higher company limits and to reflect the current HMRC evaluative framework.
07How long does HMRC SEIS / EIS Advance Assurance take after April 2026?+
HMRC's published service standard remains 4–8 weeks, often with one or more rounds of technical follow-up. Well-structured submissions with a clean risk-to-capital narrative, defensible IP positioning and aligned share classes can be approved materially faster — our most recent SEIS Advance Assurance was approved in 20 days on first read with zero queries.
