Determine the legal-form rate, reconcile accounting profit to the tax base, support deductions, depreciation, participation deductions and loss carryforwards, screen group taxation and related-party finance, and reconcile assessment payments. Includes the separately identified 2026 filing cycle for 2025 income. Use for ehf., hf., taxable partnerships, RSK 1.04 and annual tax reconciliations and approved research/development credits, cost ceilings and public-aid limits, and the stated financial-sector remuneration, additional profit and bank-liability taxes, conditional domestic mergers/splits and sole-trade incorporation. Other sector taxes, foreign credits, disputed restructuring cases and some financial instruments are outside this skill. General reference only; check the cited law before filing.
