The rules that shape this work

The merged R&D expenditure credit scheme applies for accounting periods beginning on or after 1 April 2024, with enhanced support for R&D-intensive loss-making SMEs. Claims need an additional information form filed before the claim, named claim contacts and, for most new claimants, advance notification within six months of the period end, miss the notification and the claim is lost outright.

SEIS allows a company to raise up to £250,000 lifetime, within three years of starting to trade and with gross assets under £350,000. EIS follows on with larger limits. Both are unforgiving on order of events: shares must be fully paid ordinary shares issued before any convertible converts wrongly, and a single misplaced preference right can disqualify the round.

EMI options need a qualifying company, a qualifying employee, an agreed market value and notification to HMRC within 92 days of grant. Late notification is a common and expensive error, the options lose their tax advantage for everyone in the grant.

Thresholds, rates and deadlines quoted here reflect the 2026/27 UK position. Check current GOV.UK guidance, or ask us, before you rely on them for your own company.

How we run it

We start by looking at the last filed accounts, your current records and your filing dates, then confirm a fixed scope and fee in writing.

Once the work is live you get reminders ahead of each deadline, a named person to ask questions, and a plain-English summary when the figures are ready, not a PDF with no explanation.

What Our Clients Say

Rated 4.9 out of 5From 302 Google reviews
Accotax have been our accountants for many years now. We maintained them because of their professionalism. In the last couple of years I have been working with Imran, who has been very professional and helpful in guiding us through the whole process, explaining and clarifying every aspect of it. Very prompt in responding to questions and patient with us even when we seem to be slow.
Mansur Liman · Long-standing company client
We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.
Mael Leboucher · Year end accounts & bookkeeping
I've been working with Accotax since January 2024, and their support has grown alongside my business needs. My personal allocated manager, Umer, provides tailored services for both of my companies, adapting as I expand and ensuring everything runs smoothly. They are responsive, knowledgeable, and always clear in their communication. Their help with accounts, VAT, payrolls, pensions and compliance gives me real confidence and peace of mind.

Frequently asked

Tech startup accountants: questions directors ask

Does our software development qualify for R&D relief?

Only where you are resolving genuine technological uncertainty a competent professional could not readily resolve. Routine integration, configuration and UI work does not qualify. We test the projects honestly and document the reasoning at the time.

Can we do SEIS and R&D together?

Yes, but grant funding and certain subsidies interact with R&D relief, and SEIS has its own trading and asset conditions. The sequencing needs planning before the money lands, not after.

When should we set up an EMI scheme?

Before you promise equity verbally. Once expectations are set, the valuation and the paperwork have to follow the promise rather than the other way round, which usually costs more.

Do you work with venture-backed companies?

Yes, including monthly investor packs, covenant and information-right compliance, and diligence support through a round.

What records are needed for tech startup accountants?

Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.

How much does help with tech startup accountants cost?

The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.

Can you take over tech startup accountants from another accountant?

Yes. We request professional clearance, collect the prior records and authorities, check the next Companies House and HMRC deadlines, and give you one clear handover list. The process is normally completed remotely.

Can tech startup accountants be handled online?

Yes. We work through secure cloud records, scheduled reviews and digital approvals, while keeping a named team available by phone, video call and email. Clients can also visit our Morden office by appointment.

Which accounting software works best for tech startup accountants?

We regularly work with Xero, QuickBooks, FreeAgent, Sage and connected sales or expense apps. The right setup depends on transaction volume, integrations and the reports you need, not simply the software brand.

What tax deadlines matter for tech startup accountants?

The relevant calendar may include annual accounts, Corporation Tax payment and return dates, confirmation statements, VAT returns, payroll submissions and Self Assessment. We map the dates from your company year end and registrations.
