# Sudan Personal Income Tax (ضريبة الدخل) Skill v0.1

> **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 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 before filing.

## Section 2 — Required inputs and refusal catalogue

### Required inputs

Before starting any Sudan personal income tax work, obtain:

1. **Residency status.** Resident if present in Sudan for **183 days or more** in the base period, or present in Sudan in the period and both preceding periods for 12 months or more, or has taken Sudan as place of residence with intention to settle. *(Income Tax Act 1986, terminology: "Resident")*
2. **Income categories:** employment (salary), business/professional income, rental income, or investment income
3. **Gross income** for the tax year with supporting documents
4. **Deductible expenses** with supporting documentation
5. **Withholding tax already suffered** (PAYE certificates or WHT certificates)
6. **Zakat payment certificate** (Zakat paid is deductible from business profits tax)

### Refusal catalogue

- **R-SD-1** — Do not produce a final filing figure without residency status confirmed.
- **R-SD-2** — Do not deduct an expense lacking documentary support. Disallow it.
- **R-SD-3** — Do not finalise tax using the SDG 3,000 personal allowance without verifying it has not been updated — Sudan's currency redenominations may have changed this figure.

- **R-SD-5** — Do not apply double taxation treaty rates without confirming the specific treaty is in force.
- **R-SD-6** — Do not advise on corporate income tax — this skill is individuals only.
- **R-SD-7** — Do not give a binding figure where current-year bracket/allowance values cannot be verified; provide the formula and flag "verify current value."

## Section 3 — Rates and thresholds

### Personal income tax rates (employment / salary)

Sudan taxes employment income at progressive rates. The top marginal personal income tax rate is **15%** (Trading Economics; Income Tax Act 1986). Some sources cite a range of 5%–20% with 20% being the top rate for non-residents and fringe benefits.

**AUDIT FLASH POINT:** Multiple sources cite different top rates (15% vs 20%). The 15% rate is confirmed by Trading Economics and the Sudan Tax Authority page for residents. The 20% rate appears for non-resident taxpayers and fringe benefits per the Britacom tax profile. Verify the current bracket schedule before filing.

| Category | Rate range | Source |
|----------|-----------|--------|
| **Resident employment income** | 5% – 15% (progressive) | Income Tax Act 1986; Trading Economics |
| **Non-resident employment income** | 20% (flat) | Income Tax Act 1986; Britacom tax profile |
| **Fringe benefits** | 20% | Income Tax Act 1986; Britacom tax profile |
| **Rental / real-estate income** | 10% | Income Tax Act 1986 (verify current rate) |
| **Sole proprietorship / partnership** | 0% – 20% (progressive) | Income Tax Act 1986; Britacom tax profile |
| **Capital gains (individual)** | 20% | Income Tax Act 1986; Britacom tax profile |

### Personal tax-free allowance (exemption)

All resident and non-resident individuals are eligible for a **tax-free allowance of SDG 3,000**, which can be used to offset income from:
- Self-employed ventures
- Rent income
- Professional services income

*(Income Tax Act 1986; Britacom tax profile)*

**Verify current value:** The SDG 3,000 figure predates multiple currency redenominations. Confirm against current Taxation Chamber guidance before filing.

### PAYE withholding

- Employment income tax is **withheld at source by the employer (PAYE)** and remitted monthly
- **PAYE remittance deadline:** On or before the **15th of the month following deduction** *(Income Tax Act 1986; tax.gov.sd)*

### Individual annual return deadline

- As specified in the Income Tax Act; commonly within a set period after year-end (verify current deadline — some sources indicate 30 June) *(Income Tax Act 1986; tax.gov.sd; taxratesbycountry.com)*

### Conservative defaults

| Ambiguity | Default |
|-----------|---------|
| Unknown residency | Treat as **non-resident** (Sudan-source income only, 20% flat rate) until residency confirmed |
| Unknown whether 15% or 20% applies | Use 15% for residents, 20% for non-residents; flag both |
| Unknown personal allowance current value | Use SDG 3,000 and label "verify current value" |
| Unknown whether an expense is deductible | Treat as **non-deductible** until documentary support confirmed |
| Unknown income category | Default to employment income (most common); verify |

## Section 4 — Computation rules

### Step 1 — Determine residency

An individual is **resident** if:
- (i) Present in Sudan for **183 days or more** in the base period; OR
- (ii) 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 there

*(Income Tax Act 1986, terminology section)*

Residents are taxed on income arising in Sudan AND any place outside Sudan (worldwide for residents). Non-residents are taxed on Sudan-source income only.

### Step 2 — Classify income

| Income type | Determination rule | Rate treatment |
|------------|-------------------|---------------|
| Employment income | Gross salary + allowances | Progressive 5%-15% (resident) / 20% (non-resident) |
| Business/professional income | Net profit (gross income less deductible expenses) | Progressive 0%-20% (same as sole proprietorship) |
| Rental income | Gross rent less allowable property expenses | 10% |
| Capital gains | Gain on disposal of assets | 20% |
| Interest income (bank deposits) | Exempt | 0% |
| Pensions (government/municipal) | Exempt | 0% |

### Step 3 — Apply personal allowance

```
Taxable income = Gross income - SDG 3,000 personal allowance (verify current value)
```

The SDG 3,000 allowance can offset self-employment income, rent income, and professional services income.

### Step 4 — Compute tax on progressive scale

For employment income (residents):
```
Tax = Taxable income x applicable progressive rate (5% to 15%)
```

For non-residents and fringe benefits:
```
Tax = Gross income x 20% (flat rate, no allowance — verify)
```

### Step 5 — Apply credits

```
Tax payable = Tax computed - PAYE already withheld - WHT credits
```

## Section 5 — Edge cases and special rules

### Tax exemption categories (Schedule 1, Income Tax Act 1986)

1. **Pensions** paid to members of municipal services or disciplinary departments
2. **Payments and transfers** to envoys, diplomats, and employees of international organizations
3. **Interest** from bank deposits, savings accounts, and postal savings funds
4. **Personal income of employees over 50 years old** working in government or private sectors — provided the tax-exempt income does not exceed the highest salary in the government salary plan (does not include remuneration of board members of government or state-owned enterprises)
5. **Charitable bodies** — the Minister may, after consultation with the Minister of Welfare and Social Insurance, reimburse taxes collected from legally registered charitable bodies
6. **Activities under the Zakat Act 2001** and the **Islamic Endowments Act 1996** are outside the Income Tax Act's scope entirely
7. **Expatriate personnel** working on major development projects (oil industry, dams, roads, bridges) may receive tax exemption benefits

### Residence — non-individual (companies)

For a non-individual (company), **resident** means control and management are exercised directly in Sudan in the period. *(Income Tax Act 1986)*

### Currency conversion

Documents or invoices in a currency other than SDG must be converted at the **exchange rate at the time of the transaction**, with the exchange rate used stated. *(Income Tax Act 1986, Art 39(3-5))*

### Income subject to tax (Art 4, Income Tax Act 1986)

Tax is levied for the assessment year on income from the base period arising from:
1. **Sudan** — for residents and non-residents
2. **Any place outside Sudan** — for residents

Despite any law granting tax exemption, tax is imposed on profits from commercial activity, which includes:
- Business profits
- Rental income from real estate
- Personal income
- Gross income

This applies even if the person no longer owns the income source in the assessment year.

### Record-keeping

Every person subject to tax must keep accounting books (manual or electronic) — journal, ledgers, and inventory — plus supporting documents for **not less than 6 years** after the base period, in either **Arabic or English**. *(Income Tax Act 1986, Art 39(3-5))*

### Self-assessment and penalties

Every person under self-assessment must submit their return and pay tax due at the time of filing. If the return is found incorrect after review, an **additional tax not exceeding twice (2x) the amount of tax** determined from the audit may be imposed. *(Income Tax Act 1986, Art 38(2))*

**AUDIT FLASH POINT:** The 2x penalty for self-assessment under-declaration is significant. Conservative computation is essential; do not finalise aggressive tax positions without professional review.

## Section 6 — Worked examples

### Example 1 — Resident employee, moderate income

**Scenario:** Sudanese resident employee with annual gross salary of SDG 1,200,000.

- Total income: SDG 1,200,000 (employment income)
- Less personal allowance: SDG 3,000 (verify current value)
- Taxable income: SDG 1,197,000
- Tax at progressive rates (assume 15% marginal rate):
  - Lower bands at 5%-10% + remaining at 15% (verify exact bracket schedule)
  - Estimated tax: approximately **SDG 180,000** (verify with current bracket schedule)
- Less PAYE already withheld: depends on monthly withholding
- *Flag: exact bracket computation requires confirmed bracket thresholds — verify current schedule*

### Example 2 — Non-resident consultant

**Scenario:** Non-resident consultant earns SDG 500,000 of Sudan-source professional fees.

- Non-resident rate: 20% flat
- Tax = 500,000 x 20% = **SDG 100,000**
- Personal allowance: typically not available to non-residents (verify)
- WHT may already cover this if payer withheld at source

### Example 3 — Rental income

**Scenario:** Resident landlord receives SDG 600,000 annual rental income.

- Rental income rate: 10%
- Tax = 600,000 x 10% = **SDG 60,000**
- Personal allowance may offset: SDG 60,000 - SDG 3,000 adjustment (verify whether allowance applies to rental)
- *Flag: verify whether the 10% rate is applied to gross rent or net rent after property expenses*

### Example 4 — Sole proprietor (commercial activity)

**Scenario:** Sole proprietor with annual gross receipts of SDG 2,000,000 and documented deductible expenses of SDG 800,000.

- Net profit = 2,000,000 - 800,000 = SDG 1,200,000
- Less personal allowance: SDG 3,000
- Taxable = SDG 1,197,000
- Progressive rates 0%-20% (same as sole proprietorship/partnership schedule)
- Estimated tax: approximately **SDG 200,000** at marginal rates (verify with exact bracket schedule)

### Example 5 — Employee over 50 years old (exemption)

**Scenario:** Government employee, age 55, annual salary SDG 900,000.

- Personal income of employees over 50 working in government sectors is exempt
- Condition: tax-exempt income does not exceed the highest salary in the government salary plan
- Tax = **SDG 0** (if condition met)
- *Flag: verify the "highest salary in the government salary plan" cap for the current year*
