Tax advisory for manufacturing & engineering that thinks ahead instead of reacting.
We are the tax advisors for owners and managing directors of mid-sized manufacturing, production and mechanical-engineering companies. We handle your bookkeeping and annual accounts reliably – but we also steer your depreciation, secure your research allowance and value your inventories correctly. Nationwide, digital and personal.

Personal point of contact
Sound familiar?
Problems that manufacturing owners know all too well.
We speak with managing directors from mechanical engineering, metalworking and contract manufacturing every day. This is what we hear again and again:
Your capital sits in machines – not in the bank.
High fixed assets tie up liquidity while depreciation runs over years. Your balance sheet shows a profit, but the next replacement investment isn't financed.
Your profit swings with the warehouse.
Semi-finished and finished goods, material prices and set-up costs distort the result. Depending on how inventories are valued, the reporting date shows now a profit, now a loss – without the business having changed.
You pay too much tax.
No one shows you the levers: the investment deduction (IAB) and special depreciation under § 7g (German Income Tax Act) for the next machine, the research allowance (Forschungszulage) for your design and development, the accounting options for production costs.
Fear of the next tax audit.
Inventory valuation, hidden profit distribution, transfer prices to your foreign subsidiary – you know this is exactly where the auditor starts, but no one has prepared you for it.
Your tax advisor doesn't understand your production.
Cost of goods manufactured, series and job-order production, warranty provisions, intra-Community supplies – you first have to explain to your advisor how your plant even calculates its costs.
Business succession is unresolved for tax.
Millions in business assets, but no plan for the handover. Without the relief under § 13a/§ 13b ErbStG (German Inheritance Tax Act) inheritance tax can arise that the company has to pay out of its substance.
What changes for you
More clarity. Fewer taxes. More time for your production.
We are not a classic tax firm. We deliver what you as management really need – results, not just ring binders.
Crystal-clear numbers – despite fixed assets.
A live P&L with a clean depreciation view and valued inventories. You see the real production margin and know which investment you can afford and when – not only once the annual accounts arrive.
Depreciation actively steered.
We plan depreciation, the investment deduction (IAB) and special depreciation under § 7g so your replacement investments lower profit exactly when you need it – and liquidity grows with it.
Noticeably lower tax burden.
The research allowance for design and development, the accounting options for production costs, provisions for warranty and dismantling – we check every lever proactively.
No surprises from the tax office.
We prepare your tax audit, document inventory valuation and transfer prices cleanly and plan your tax in advance. You know months earlier what is coming.
Time that flows into production.
Receipts via app, banking automated, incoming supplier invoices booked directly. No more evenings spent on inventory and investment bookkeeping.
Succession that protects the substance.
We structure the handover of your business early and use the relief for business assets – so the next generation keeps the plant, not the tax office.

Personally from Karsten Guhr
A manufacturing company rarely fails for a lack of orders. It fails because of tied-up capital, an inventory valuation that distorts profit and a business succession no one calculated through in time. That is exactly where we come in: we steer your depreciation, secure your research allowance and protect the relief for your business assets – so you lead strategically instead of just reacting.
We know your business
We speak engineering language.
Depreciation and fixed assets, IAB and § 7g, production costs, inventory valuation, research allowance, intra-Community supplies, transfer pricing – we know how a manufacturing operation ticks. So you waste no time explaining your business model.

- 01
Depreciation steering & fixed assets
Useful lives, declining-balance and straight-line depreciation, the component approach – we steer the depreciation of your machine park so that profit and liquidity line up.
- 02
IAB & special depreciation § 7g
Up to 50% of planned investments deducted in advance (IAB) plus 20% special depreciation for machines, plant and tooling – profit-reducing in exactly the right year.
- 03
Research allowance for design & development
In-house design, prototype building, process and product development – up to €1m allowance per year under the FZulG (Research Allowance Act). We handle the certificate and the application.
- 04
Production costs & accounting options
Manufacturing overheads, material and administrative shares correctly included in production costs under § 255 HGB (German Commercial Code) – the accounting options used deliberately to your advantage.
- 05
Valuing semi-finished & finished goods
Inventories and work in progress valued in a legally sound way at the balance-sheet date – so no phantom profits arise and no audit challenges follow.
- 06
Provisions: warranty, dismantling, losses
Warranty, dismantling obligations and impending losses from pending transactions provisioned correctly – lowering profit in the right year.
- 07
Export, EU supplies & customs
Intra-Community supplies, exports, chain transactions and customs matters mapped cleanly – legally sound for VAT, even with complex supply chains.
- 08
Transfer pricing & permanent establishments
Transfer pricing to foreign subsidiaries and foreign permanent establishments documented – audit-proof to the requirements of the tax audit.
Industry benchmarks
We know the margins in your industry. And get more out for you.
We look after more than 50 manufacturing and engineering companies in Germany and see real balance sheets every month – not trade-show brochures. We know what EBIT margin is typical in your segment, where you should be and which tax levers pull your after-tax result upward.
Typical EBIT range (mid-sized)
- 6 – 12 %Machinery & plant engineeringProject- and order-driven · high capital tie-up · § 7g as a lever
- 4 – 9 %Metalworking / suppliersOEM price pressure · inventory and depreciation steering is decisive
- 6 – 11 %Plastics & electricalTooling- and energy-intensive · check special depreciation and relief schemes
- 5 – 10 %Contract manufacturingUtilisation-driven · low material depth · keep capital tie-up in view
This is how we lift your after-tax result – legally and without balance-sheet acrobatics:
- IAB & special depreciation § 7gUp to 50% of planned investments deducted in advance (IAB) plus 20% special depreciation for machines and plant – so replacement and expansion investments lower profit in exactly the right year.
- Research allowance (FZulG)Up to €1m per year for design, prototype building and process development. Many engineering firms don't know that routine development in the plant often qualifies.
- Steer production costsThe accounting options under § 255 HGB used deliberately – so you shift profit predictably between years and smooth tax progression and advance payments.
- Build up provisionsWarranty, dismantling and impending losses provisioned in a legally sound way – lowering taxable profit in the right year instead of surprising you later.
- Holding & MD compensationPark participation income via a holding effectively at around 1.5% tax and align the managing-director salary optimally with your margin and tax allowance.
- Relief for business assetsThe handover structured early and the standard or optional relief under § 13a/§ 13b ErbStG used – inheritance and gift tax often drop to zero.
