Deduct Business Expenses Before Registration 2026: The Full Guide

Most founders assume the clock for deductible expenses starts only when they register their business. Wrong. What you spend on a laptop, technical books, courses or research trips before you officially launch can be tax-deductible – as so-called anticipated business expenses (vorweggenommene Betriebsausgaben).

The decisive concept is "business causation" (§ 4 (4) EStG). As soon as an expense has a clear, provable connection to your planned self-employed activity, it counts – even if it was incurred months before your first euro of revenue. There is no rigid deadline for how far back you can go; what matters is the economic connection.

This guide explains which pre-launch costs qualify, how far back you can claim, what happens with input VAT, and how to document everything so the tax office does not strike it.

What are anticipated business expenses?

Anticipated business expenses (also "pre-incurred operating expenses") are costs you have before you actually start your self-employed activity, but which are already caused by that activity. You are investing in the future business even though no revenue is flowing yet.

The principle is well established: the deduction under § 4 (4) EStG does not depend on your trade registration or your first contract, but on business causation. So anyone seriously building a self-employed business may claim the start-up costs.

Which costs typically qualify?

Common anticipated business expenses for freelancers and the self-employed:

• Work equipment: laptop, monitor, software subscriptions, technical books, tools
• Qualification: courses, seminars, certificates, coaching for the planned activity
• Market and competitor research: trips to potential clients or trade fairs
• Start-up advice: tax advisor, lawyer, notary (where business-related)
• Online presence: domain, web hosting, logo, first website
• Fees: chamber of commerce consultation, registration costs, permits

Important: the expense must target the specifically planned activity. A generic language course "just in case" is not enough – a bookkeeping seminar for your planned consulting practice is.

How far back can you go?

There is no fixed deadline in the law. What matters is that you can credibly demonstrate the link between the expense and the later activity. The closer the expense is in time to your launch and the more specific it is to your business, the more easily the tax office accepts it.

For long-lived purchases such as a laptop, depreciation also applies: if the net price is below the GWG threshold of 800 euros, you deduct it in full immediately. More expensive devices are spread over their useful life – and depreciation can start with the opening of the business.

Input VAT from before registration

Input VAT can also be deducted before you are registered for VAT – provided you are not a small business (Kleinunternehmer) and the input service was intended for your future, VAT-liable business. Entrepreneur status under § 2 UStG begins as soon as you take the first serious preparatory steps.

The condition is a proper invoice with all mandatory details, issued in your name. You then reclaim the VAT paid via your first VAT return. Anyone who opts for the small-business rule, by contrast, cannot deduct input VAT.

Collect receipts – from day one

The most common mistake: receipts from the pre-launch phase are missing or made out as "private". Collect every receipt from the moment you decide to go self-employed. Make sure of:

• Invoices with your full name and date
• Proof of payment (bank statement, ideally from a separate account)
• A short note on the business purpose

Digitise the receipts in a GoBD-compliant way – the receipt management guide shows how. A clean receipt system is half the battle when the tax office asks questions.

How to enter the costs in your taxes

You record anticipated business expenses in the EÜR (cash-basis profit calculation) of the year in which they were incurred – even if the business only formally starts later. If this creates a loss, you can offset it against other income or carry it forward.

Practical sequence:

1. Register the activity with the tax office – see the tax registration questionnaire and trade registration.
2. Book all start-up costs as business expenses in the EÜR.
3. Reclaim input VAT (if on standard taxation) via the VAT return.

With Norman you automatically assign receipts and expenses to the right categories and prepare your EÜR and VAT return directly – ideal when you are just starting out and do not want to build up account and receipt chaos.

Conclusion

Anticipated business expenses are real money that many founders give away because they start collecting receipts too late. There is no deadline – only business causation counts. Anyone who documents cleanly from the start significantly lowers their tax burden in the first year and can even use losses.
