Germany clarifies own-share trading movements in the tax contribution account

Published 2 min read

On 16 October 2026, Germany’s Federal Ministry of Finance added guidance on short-term trading in a company’s own shares. New paragraph 19a applies the existing tax-contribution-account rules only to the net change in own-share holdings at the relevant balance-sheet dates.

Official document:
BMF letter IV C 2 - S 2742/00111/003/021 of 16 October 2026; new paragraph 19a of BMF letter of 27 November 2013, BStBl I 1615; KStG section 27
Development date:

Net holdings, not gross trading turnover

The amendment concerns short-term proprietary trading in own shares. It inserts a new subsection after paragraph 19 of the Ministry’s 27 November 2013 letter. The relevant comparison is the change in the stock of own shares between balance-sheet dates, rather than treating every intervening purchase and resale as a separate movement for this account.[1]

Why the account matters

Section 27 of the Corporation Tax Act requires a company subject to unlimited German corporate tax to record contributions outside nominal capital in a separate tax account at each financial year-end. It rolls forward additions and reductions and separately assesses the closing balance. This is not simply the company’s commercial share-capital figure.[3]

The 2013 guidance treats an own-share purchase at company level as a capital reduction and a resale as a capital increase, rather than ordinary acquisition and disposal transactions. Its paragraphs 9 and 13 explain how payments above nominal value can affect the contribution account; the resale does not generate a taxable disposal profit or loss at company level.[2]

A bounded administrative clarification

Our practical reading is that a group with short-term own-share turnover should reconcile its opening and closing holdings before applying the account-movement rules. The new paragraph addresses those movements; it is not a new corporate tax rate, an exemption for trading profits generally, or a shareholder-level disposal rule.[1][2]

The one-page letter does not specify a separate commencement date or detailed numerical example. The older letter’s shareholder and transitional sections remain separate context. The clarification should therefore not be expanded into a conclusion that all buy-backs, cancellations or shareholder tax consequences are determined solely by a net balance.[1][2]
