Territorial + person hybrid
Sudan combines the territoriality and person principles: - Residents taxed on income arising in Sudan AND any place outside Sudan (worldwide for residents) - Non-residents taxed on Sudan-source income onlyIncome Tax Act 1986
Residency tests
For an **individual**: - Present in Sudan for 183 days or more in the period, OR - Present in Sudan in the period and both preceding periods for 12 months or more, OR - Has taken Sudan as their place of residence and shown intention to settle For a **non-individual (company)**: - Control and management are exercised directly in Sudan in the period *(Income Tax Act 1986, terminology section)*Income Tax Act 1986, terminology section
Rendered from the canonical facts model. General reference only — confirm with a qualified professional before acting.
General reference only. This skill is general tax/accounting reference material for AI-assisted workflows. It has not been reviewed for any specific person's facts, documents, elections, deadlines, residency, filing status, or local procedures. Do not rely on it to file, pay, amend, or take a tax position without review by a qualified professional in the relevant jurisdiction.
Currency note: All figures are in Sudanese Pounds (SDG — ج.س). Sudan has undergone multiple currency redenominations; verify current SDG values before filing. YMYL — verify before relying. Sudan's tax legislation has been subject to amendments and the political situation (post-2021 military takeover, ongoing conflict since April 2023) has disrupted tax administration. Where this skill says "verify current value," re-confirm against the Sudan Taxation Chamber (tax.gov.sd), PwC Worldwide Tax Summaries, or a qualified Sudan accountant.
