Tax advisory for SaaS founders who want to scale.
We are the tax advisory for founders of SaaS, platform and tech startups – from pre-seed to Series B. We handle your bookkeeping and annual accounts reliably – and beyond that we think in ARR, runway and cap table, rescue loss carryforwards through financing rounds and structure you cleanly all the way to exit. Nationwide, digital and personal.

A personal point of contact
Sound familiar?
Problems SaaS founders know all too well.
We talk to founders of SaaS and tech startups every day – VC-backed or bootstrapped. This is what we hear again and again:
Your financing round destroys your loss carryforwards.
An investor comes in, more than 50% of the shares change hands – and § 8c KStG (German Corporate Tax Act) wipes out the loss carryforwards you built up over years. No one warned you.
ARR is growing, but your advisor books by bank balance.
Prepaid annual subscriptions land in revenue all at once instead of being recognized over time. Your P&L shows numbers that have nothing to do with your real MRR reality.
Your ESOP triggers a dry-income problem.
Employees are asked to pay tax on something they haven't received in cash yet. Without a clean § 19a structure, equity becomes a burden instead of an incentive.
Convertible loans and SAFEs are a tax black box.
Convertible loans, discounts, caps, hidden capital contributions – your advisor doesn't understand the mechanics, and closing the next round gets expensive.
VAT on international customers is a minefield.
US customers, EU B2B, digital services, OSS, reverse charge – you're never quite sure whether you're invoicing correctly. Getting it wrong either way costs you.
The exit is near – and you have no holding company.
Sell as an individual and partial-income taxation applies. Founders who don't set up a holding BEFORE the term sheet often leave a seven-figure tax amount on the table.
What changes for you
More runway. Lower taxes. A cap table that won't surprise you.
We are not a classic tax firm. We deliver what you actually need as a founder – results that protect your valuation and your runway.
Loss carryforwards that survive rounds.
We protect your loss carryforwards through financing rounds using the continuation-bound loss carryforward under § 8d KStG – cleanly documented and filed in time.
Numbers that convince investors.
Period-accurate revenue recognition, ARR/MRR-consistent reporting and a P&L that holds up in the data room – rather than being corrected during due diligence.
ESOP without the dry-income trap.
We structure VSOP and ESOP so that § 19a EStG (Income Tax Act) and the German Future Financing Act apply – your team gets equity without untaxed phantom income.
Runway you can actually steer.
Liquidity and runway planning with real cash-burn scenarios. You know months in advance when the next round has to close – not when the bank account starts beeping.
Grants you'd otherwise leave behind.
R&D tax credit under the FZulG (Research Allowance Act), the INVEST grant, the IAB investment deduction – we secure capital that doesn't dilute your round and cuts your burn directly.
An exit setup that's ready in time.
Founder holding, § 8b KStG, cap-table hygiene – we build the structure that makes 95% of the sale tax-free, long before a buyer knocks.

Personally from Karsten Guhr
A startup rarely fails because of a bad product. It fails because of a financing round where no one thought about § 8c, an ESOP with a dry-income trap, or an exit without a holding structure. That's exactly where we come in: we think your tax structure far enough ahead that every round and every exit makes you stronger – instead of costing you millions.
We know your business
We speak SaaS.
ARR, MRR, net revenue retention, cap table, convertible, vesting, runway, rule of 40 – we know how a SaaS startup ticks. So you don't waste time explaining your business model or your metrics to us.

- 01
Revenue recognition & deferred revenue
Prepaid annual and multi-year subscriptions recognized over time via deferred revenue (passive RAP) – your P&L reflects real MRR, not the day the cash landed.
- 02
Loss carryforwards & § 8c/§ 8d KStG
A change of shareholders in a round threatens to forfeit your losses. The continuation-bound loss carryforward under § 8d KStG is often the rescue.
- 03
Convertible loans & SAFEs
Convertibles, discounts, caps, investment agreements – mapped cleanly for tax and synced with the cap table before the round closes.
- 04
ESOP / VSOP & § 19a EStG
Employee equity without dry income: we use § 19a EStG and the German Future Financing Act so tax applies only on real cash inflow.
- 05
International VAT
OSS scheme, reverse charge, digital B2B and B2C services, US customers – one clean setup for your cross-border revenue.
- 06
R&D grants & software capitalization
R&D tax credit under the FZulG for your development work – plus a clean assessment of when self-created software must be capitalized.
- 07
Founder holding before exit
Holding your shares in a company rather than privately: at sale, capital gains are effectively ~95% tax-free under § 8b KStG.
- 08
Runway & liquidity planning
Cash burn, runway scenarios and investor reporting – numbers you plan the next round with instead of chasing after it.
Industry benchmarks
We know your industry's metrics. And protect them for tax.
We support more than 40 SaaS and tech startups and see real numbers – not pitch decks. SaaS is mostly growth-driven, with EBIT deliberately negative. We know where you should sit on gross margin, rule of 40 and net revenue retention, and which levers pull your tax bill down and your runway up.
Typical metrics (gross margin / rule of 40)
- 70 – 80% GMPre-seed / seedEBIT deliberately negative · runway & loss carryforwards are the decisive factor
- Rule of 40 ≥ 40%Series A / BGrowth + margin combined · net revenue retention above 100% is the target
- 15 – 30% EBITBootstrapped / profitableCash-flow driven · distribution and holding strategy pays off
- 80 – 85% GMVertical SaaSHigh gross margin · CAC payback and NRR drive the valuation
How we lower your tax bill and extend your runway – legally and without balance-sheet acrobatics:
- Continuation-bound loss carryforward§ 8d KStG rescues loss carryforwards that § 8c would otherwise destroy on a change of shareholders – filed in time and cleanly documented, often worth seven figures.
- Founder holding (§ 8b KStG)Move your shares into a holding before exit: capital gains stay effectively ~95% tax-free – instead of partial-income taxation at the personal level.
- R&D tax credit (FZulG)Up to €3.5m assessment base per year – the credit is paid out, cuts your cash burn directly and doesn't dilute your round.
- ESOP/VSOP under § 19a EStGEmployee equity without dry income and without ongoing payroll cost – it retains key people without straining your runway.
- Investment deduction (IAB)Deduct up to 50% of planned investments in advance to reduce profit – for servers, hardware and the tech infrastructure behind your stack.
- INVEST grant & fundingINVEST makes your angel round more attractive for investors and eases your fundraising – we review and manage the applications.
