- WHY TDA
Why Choose TDA
Revenue recognised correctly
SaaS revenue deferred to the correct period means your profit figures actually reflect the health of the business that is essential for accurate valuation and investor conversations.
R&D credits claimed every year
Most SaaS businesses qualify for R&D Tax Credits on their development activity. We assess, calculate, and submit the claim as part of your annual Corporation Tax return, typically recovering 16–25p per £1 of qualifying spend.
Investor-ready from day one
Your management accounts and financial model are structured in the way investors and due diligence teams expect, with ARR, churn, CAC, and LTV alongside traditional P&L.
VAT on international sales handled
Digital services sold to B2C customers in EU countries require registration under the OSS (One Stop Shop) regime. We manage this compliance to prevent penalties from EU tax authorities.
Share option scheme compliance
EMI options, growth shares, and other equity incentives require careful accounting and HMRC notification. We manage this accurately from the grant through to exercise.
FAQ
Frequently Asked Questions
SaaS revenue should be recognised over the period to which it relates — not when payment is received. Annual subscription payments received upfront are treated as deferred income on the balance sheet and recognised monthly as the service is provided. This matters for both financial reporting (giving an accurate picture of the business) and Corporation Tax (the taxable profit in each period must reflect the revenue actually earned). We set up your accounting system to handle this automatically.
In most cases, yes. The R&D Tax Credit scheme covers the development of software, platforms, and digital products where the work involves overcoming technical uncertainty — developing something that is not straightforward to achieve. The qualifying costs include employee time spent on R&D activities, subcontractor costs, and consumables. Under the merged scheme (April 2024 onwards), qualifying companies receive a 20% credit against Corporation Tax on the enhanced deduction. We assess your qualifying activity and prepare the claim every year.
The Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) provide tax reliefs to investors in qualifying early-stage UK companies. To maintain EIS/SEIS compliance, your company must meet ongoing conditions — trading requirements, spending of raised funds, and restrictions on certain activities. We ensure your accounting and business activities remain compliant with EIS/SEIS rules throughout the investment period, and produce the reports your investors need for their own tax claims.
If you sell digital services (software subscriptions, SaaS, digital content) to consumers (B2C) in EU countries, you must collect and remit VAT at the applicable rate in each customer’s country. The EU One Stop Shop (OSS) regime allows you to register in one EU country and file a single quarterly return for all EU sales. UK businesses can use the Non-Union OSS scheme. We manage your OSS registration, quarterly filings, and the VAT accounting for international sales.
The most common equity incentive schemes for UK tech companies are: EMI (Enterprise Management Incentives) — the most tax-efficient option for qualifying companies; CSOP (Company Share Option Plan) — for companies above EMI size limits; and growth shares or hurdle shares, which are a class of ordinary share designed to give employees upside above a set valuation. Each scheme has specific HMRC notification requirements, accounting treatment under FRS 102, and tax implications on grant, vesting, and exercise. We handle the full accounting and compliance for each.
