Individual Income Tax Return Tanzania: Who Files, the Estimate and Instalments, the 30 June Deadline and Penalties
Who must file an individual income tax return in Tanzania, and by when? A resident individual with business income, or other income not fully taxed at source, files a statement of estimated tax by 31 March and pays four quarterly instalments. The final return is due within six months after year end: 30 June 2027 for 2026. Employees taxed only through PAYE by a resident employer, and presumptive traders, do not file.
This guide follows the individual income tax return Tanzania requires, from the TIN to the final return, with a worked example for a resident consultant.
Who should read this
- Resident sole traders and consultants whose turnover is above the TZS 200 million presumptive ceiling, or who have opted out of the presumptive regime.
- Salaried employees with a side income or pay from an employer abroad.
- Landlords and investors with rent, interest or dividends.
- Expatriates and returning Tanzanians with income abroad.
- Non-resident individuals with business income in Tanzania that is not fully taxed at source.
Companies follow our corporate income tax return guide instead.
What the law says
The Income Tax Act, Cap. 332 R.E. 2023 sets the charge to tax and the duty to file. The Tax Administration Act, Cap. 438 R.E. 2023 runs the machinery: TIN, records, extensions, assessments, objections, interest and penalties. The Revised Edition 2023 renumbered the Income Tax Act from Part V onwards, so older guides cite different section numbers.
| Topic | Section | Act |
|---|---|---|
| Final withholding payments | s.111 | Income Tax Act |
| Credit for non-final withholding | s.112 | Income Tax Act |
| Quarterly instalments | s.113 | Income Tax Act |
| Statement of estimated tax payable | s.114 | Income Tax Act |
| Returns of income; return not required | s.117; s.118 | Income Tax Act |
| Self-assessment | s.120 | Income Tax Act |
| Records; tax returns; electronic filing; extension | s.43; s.45; s.46; s.48 | Tax Administration Act |
| Objection to a tax decision | s.62 | Tax Administration Act |
| Interest; penalties | ss.86 and 87; ss.88 to 90 | Tax Administration Act |
We cite these provisions at section level. Read the operative wording in the TRA copy before quoting it to TRA.
The year of income for an individual is the calendar year. PwC's individual tax administration summary, last reviewed 9 September 2026, notes that another year end needs the Commissioner's approval.
What changed in 2026 for individual taxpayers?
The Finance Act, 2026 took effect on 1 July 2026. Four changes touch the individual file.
- Presumptive ceiling doubled. The turnover limit rose from TZS 100 million to TZS 200 million (register line F0194).
- Top presumptive band rose. Turnover from TZS 11,000,001 to TZS 200,000,000 now pays 4.0% of turnover, up from 3.5% (F0193).
- New-business holiday. A new individual business with turnover from TZS 4,000,001 to TZS 200,000,000 pays nil for the first 12 months from the date it obtains its TIN (F0190).
- TIN within 15 days. A person starting employment, a business or an investment applies for a TIN within 15 days (NEW-02-17).
EY's alert of 17 July 2026 and Clyde & Co's note of 3 July 2026 report the same ceiling and rate. EY adds that the holiday needs Commissioner General approval and may carry conditions in regulations not yet issued.
The resident individual bands did not change (F0181).
The filing system changed too. TRA's Integrated Domestic Revenue Administration System (IDRAS) took effect on 9 February 2026, as Daily News reported on 3 February 2026 from a TRA statement.
Who must file an individual income tax return in Tanzania?
The starting rule is section 117: a person liable to income tax files a return of income for each year. Section 118 then lists cases where no return is needed unless the Commissioner asks for one. TRA's income tax for individuals page sorts individuals into two groups: those under the presumptive regime and those outside it.
| Your position | Final return? | Estimate and instalments? | Basis |
|---|---|---|---|
| Resident, salary only, PAYE withheld by a resident employer | No | No | s.118; PwC |
| Resident presumptive trader, turnover up to TZS 200 million | No; TRA assesses the presumptive tax | Instalments allowed where the tax exceeds TZS 50,000 a year | TRA page; F0189 to F0193 |
| Resident, business turnover above TZS 200 million, or opted out | Yes, with accounts | Yes | F0194; ss.113, 114, 117 |
| Resident, salary plus business or consulting income | Yes | Yes, for the income outside PAYE | ss.113, 117 |
| Resident, rent, interest and dividends all taxed by final withholding | Not for that income | No | s.111; PwC |
| Non-resident employee | No; the 15% withheld is final | No | F0182 |
| Non-resident with business income in Tanzania | Yes (verify) | Yes (verify) | ss.113, 117; F0183 |
A TIN comes first. Our guide to TIN registration in 2026 covers the application. The register shows no prescribed fee for a TIN (NEW-02-17).
When can an employee skip the return?
An employee is outside the return when the only taxable income is employment income from a resident employer. The employer has withheld PAYE each month at the bands, and that settles the year. PwC's summary states this exemption.
Three situations bring an employee back into the return:
- Side income. Consulting fees, a shop, a farm business or commissions. The 5% withheld from a resident's service fees is not final (F0212), so the fees go in the return and the 5% comes off the tax.
- A foreign employer. Pay from a non-resident employer with no Tanzanian payroll is not employment income from a resident employer. Nobody withholds PAYE, so the employee pays by instalment and files.
- Income abroad. A resident who is not a short-term resident is taxed on worldwide income, so foreign rent or business profit brings a return.
A second job is a separate case. The secondary employer withholds at 30% (F0184), and whether TRA expects a return to reconcile the year should be confirmed. Our PAYE guide shows how the monthly bands work on a payslip.
Do non-residents file a Tanzanian return?
A non-resident individual is taxed only on Tanzanian-source income. PwC's personal income summary records a flat 15% on a non-resident's employment income, withheld as a final tax (F0182). Other income of a non-resident individual is taxed at 30% (F0183).
Where all Tanzanian income is taxed by final withholding, the non-resident has nothing to put in a return. Business profit earned here through a fixed place or a project belongs in a return, with instalments.
Residence is decided year by year under section 86. Our guide to tax residence in Tanzania sets out the 183-day, 122-day and permanent home tests.
How do the estimate and instalments work for individuals?
Section 113 requires a person who derives, or expects to derive, business or investment income in the year to pay tax by quarterly instalments. Section 114 requires a statement of estimated tax payable by the first instalment date. TRA's individuals page names the forms: ITX200.01.E for the estimate and ITX201.01.E for the final return.
- Statement of estimated tax: within three months from the start of the year, so 31 March for a calendar year.
- Instalments: 31 March, 30 June, 30 September and 31 December.
- Amount: the estimated tax for the year, less expected credits for non-final withholding, spread over the instalments.
The estimate carries a test. Where it is below 80% of the correct tax, interest runs on the shortfall at the statutory rate (NEW-02-10), under section 86 of the Tax Administration Act. TRA's interest and penalties page states the 80% rule.
Our provisional tax guide works through the instalment arithmetic in detail, so this page does not repeat it.
How are the resident individual bands applied for a full year?
The First Schedule sets the bands as monthly figures for PAYE. For an annual return the same bands apply to the year, multiplied by twelve. The annual tax-free threshold is TZS 3,240,000, or TZS 270,000 a month (F0181). TRA's individuals page states that the rates are the same for Mainland Tanzania and Zanzibar.
| Annual chargeable income (TZS) | Tax | Monthly register line |
|---|---|---|
| 0 to 3,240,000 | Nil | F0176 |
| 3,240,001 to 6,240,000 | 8% of the amount above 3,240,000 | F0177 |
| 6,240,001 to 9,120,000 | 240,000 plus 20% of the amount above 6,240,000 | F0178 |
| 9,120,001 to 12,000,000 | 816,000 plus 25% of the amount above 9,120,000 | F0179 |
| Above 12,000,000 | 1,536,000 plus 30% of the amount above 12,000,000 | F0180 |
The register confirms the annual cut-offs. The fixed amounts of TZS 240,000, 816,000 and 1,536,000 are our arithmetic from the monthly lines.
Business income, employment income and other chargeable income are added together before the bands apply. Tax already withheld on income in the return, including PAYE and non-final withholding, is credited against the result. Income taxed by final withholding stays outside.
Presumptive tax or a full return: which applies?
The presumptive regime is for a resident individual whose income comes only from a business sourced in Tanzania, with turnover up to TZS 200 million, who has not opted out. TRA's individuals page lists those four conditions. The tax is set by turnover, not profit.
| Annual turnover (TZS) | Without complete records | With complete records | Register ID |
|---|---|---|---|
| Up to 4,000,000 | Nil | Nil | F0189 |
| 4,000,001 to 7,000,000 | TZS 100,000 | 3% of turnover above 4,000,000 | F0191 |
| 7,000,001 to 11,000,000 | TZS 250,000 | TZS 90,000 plus 3% of turnover above 7,000,000 | F0192 |
| 11,000,001 to 200,000,000 | 4.0% of turnover | 4.0% of turnover | F0193 |
| New business, 4,000,001 to 200,000,000 | Nil for 12 months from the TIN | Nil for 12 months from the TIN | F0190 |
| Above 200,000,000 | Outside the regime: estimate, instalments and a return with accounts at the bands | F0194 | |
"Complete records" means records kept as section 43 of the Tax Administration Act requires. TRA says a presumptive trader files no return and may pay by instalments where the assessed tax exceeds TZS 50,000 a year. Near the end of the 12-month holiday, the trader submits a turnover declaration within the last 30 days.
Opting out can pay when margins are thin. At TZS 150 million of turnover the presumptive tax is TZS 6,000,000, while a real profit of TZS 15 million would cost TZS 2,436,000 at the bands. The price is the estimate, the instalments and a return with accounts. Our presumptive tax guide covers the trader's side of that choice.
How do rent, interest and dividends fit with the return?
Section 111 makes some withholding final. When a payer withholds a final payment, the income stays out of the return and the tax withheld is not credited. PwC's income determination summary, last reviewed 9 September 2026, lists the main final items for a resident individual.
- Interest: 10% withheld (F0208), final unless the interest is business income.
- Dividends: 10% (F0207), or 5% from a company listed on the Dar es Salaam Stock Exchange (F0205), final.
- Rent on land and buildings: 10% withheld by the tenant (F0214), final for a resident individual unless the rent is earned in the course of a business.
- Gains on land and buildings: paid as a single instalment at the time of sale under section 115, at 10% of the gain or, without cost records, 3% of the incomings or approved value (F0480).
Rent paid by a household tenant is the gap. Individuals renting a home have not withheld since 1 July 2023, so no final tax has been paid on that rent and the landlord must account for it. Our rental income tax guide sets out the methods and flags what TRA has not published.
A landlord letting as a business includes the rent at the bands, deducts costs and credits the 10% withheld. See our guides to withholding on dividends and capital gains on property.
Is foreign income of a resident included?
Yes, for most residents. A resident individual is taxed on worldwide income, as PwC's personal income summary confirms. Foreign business profit, foreign rent and foreign interest go into the Tanzanian return, quantified in shillings under section 28.
Two rules soften this:
- Short-term residents. Section 6(2) treats a person resident for two years or less in total like a non-resident for scope. Foreign income stays out until the third resident year.
- Foreign tax credit. Section 98 gives credit for foreign income tax paid on foreign income, capped at the Tanzanian average rate on that income. A treaty may also apply; see our guide to Tanzania's double tax treaties.
Keep the foreign assessment and proof of payment, because TRA can refuse a credit that is not supported.
What records must an individual keep?
Section 43 of the Tax Administration Act requires a taxpayer to keep the documents needed to work out tax. TRA's individuals page says they are kept for at least five years from the end of the year of income they relate to, unless the Commissioner directs otherwise.
- Sales records and the fiscal receipts issued for each sale.
- Purchase invoices backed by fiscal receipts, which section 11(4) of the Income Tax Act has required for a deduction since the Finance Act 2024.
- Withholding certificates, bank statements, leases and foreign tax receipts.
- Copies of the estimate, return, control numbers and payment receipts.
Failing to keep records costs 1 currency point, TZS 20,000, a month for an individual (NEW-02-07). For a presumptive trader, records also decide which column of the table applies. A trader selling to the public may also need a fiscal device; see who needs an EFD machine.
How do you file on the TRA portal?
Returns are filed electronically under section 46 of the Tax Administration Act. TRA's Taxpayer Portal FAQ gives the address as taxpayerportal.tra.go.tz. Since 9 February 2026, TRA's domestic tax services run on IDRAS, which TRA described in a news item of 31 December 2025. PKF's note of 5 February 2026 describes it as one system for registration, returns, payments, receipts and assessments.
In practice the individual logs in with the TIN credentials, files form ITX200.01.E by 31 March, pays each instalment against a control number, and files form ITX201.01.E with the accounts by 30 June. Save each acknowledgement and check the taxpayer ledger afterwards.
We have not verified the current IDRAS menu path for individual returns, so confirm it before the deadline. An extension of time to file must be requested in writing before the due date, under section 48.
What happens if you file or pay late?
Penalties and interest sit in Part XI of the Tax Administration Act. TRA's interest and penalties page sets out the rules and puts the currency point at TZS 20,000 (NEW-02-05).
| Failure | Charge for an individual | Register ID | TAA section |
|---|---|---|---|
| Late return | Higher of 2.5% of tax assessed less tax paid, or 5 currency points (TZS 100,000), per month or part month | NEW-02-06 | s.89 |
| Late payment | Interest at the statutory rate, compounded monthly | NEW-02-08 | s.87 |
| Estimate below 80% of the correct tax | Interest at the statutory rate on the shortfall | NEW-02-10 | s.86 |
| No records | 1 currency point (TZS 20,000) per month | NEW-02-07 | s.88 |
| False or misleading statement | 50% or 75% of the tax shortfall | NEW-02-11 | s.90 |
The statutory rate follows the Bank of Tanzania discount rate. The register shows 8.75% for the third quarter of 2026 (NEW-02-09). Because of the fixed floor, a late return draws a penalty even when little tax is outstanding.
Remission can be sought under section 81; see our TRA penalties and interest guide.
How do you object to an assessment?
A return is a self-assessment under section 120, and TRA can adjust it after an audit. PwC notes a five-year limit for TRA to adjust an income tax return, with no limit for fraud or wilful neglect.
An objection follows section 62 of the Tax Administration Act. TRA's objections and appeals page sets out the steps:
- Lodge the notice of objection within 30 days of service of the decision.
- Pay the greater of the tax not in dispute or one third of the assessed tax, so the objection is admitted (NEW-02-19).
- Apply within 15 days if a waiver or reduction of that deposit is justified.
- After the Commissioner General decides, appeal to the Tax Revenue Appeals Board: notice within 30 days and appeal within 45 days.
Board and Tribunal hearings belong with an advocate. Our guide to appealing a TRA assessment covers the Board, the Tribunal and their fees.
Zanzibar: who collects income tax on the islands?
Income tax is a Union matter. TRA administers it in Zanzibar under the same Act and on the same dates. The Zanzibar Revenue Authority (ZRA) administers only the non-Union taxes, such as Zanzibar VAT, the hotel levy and stamp duty. ZRA replaced the Zanzibar Revenue Board (ZRB) under an Act passed in January 2023, as Beako Law reported on 7 March 2023.
| Item | Mainland Tanzania | Zanzibar |
|---|---|---|
| Individual return, estimate and instalments | TRA | TRA |
| Resident individual bands | First Schedule (F0176 to F0181) | Same bands, per TRA |
| Presumptive regime | TRA, Cap. 332 | TRA, Cap. 332 |
| VAT | TRA, 18%, threshold TZS 200 million (F0239, F0242) | ZRA, 15%, threshold TZS 100 million (F0246) |
Section 99 of the Income Tax Act gives a tax credit for a business operating in both Mainland Tanzania and Zanzibar. One income tax return goes to TRA; island VAT is a ZRA matter. Our guide to Union and non-Union taxes maps the split.
Worked example: a resident consultant with fees, rent and interest
Neema is a hypothetical resident individual in Dar es Salaam. She runs a consulting practice as a sole trader and owns one flat let to a company. All figures are illustrative and apply the 2026 rules.
| Item | Amount (TZS) | Treatment |
|---|---|---|
| Consulting fees (turnover) | 240,000,000 | Above TZS 200 million, so outside presumptive tax (F0194) |
| Deductible costs backed by fiscal receipts | 180,000,000 | Deducted |
| Business income in the return | 60,000,000 | Taxed at the bands |
| 5% withheld by corporate clients on TZS 160,000,000 of fees | 8,000,000 | Non-final; credited (F0212, s.112) |
| 10% withheld by the company tenant on TZS 24,000,000 of rent | 2,400,000 | Final (F0214, s.111); rent stays out |
| 10% withheld by the bank on TZS 3,000,000 of interest | 300,000 | Final (F0208); interest stays out |
| Tax at the bands on 60,000,000 | 15,936,000 | 1,536,000 plus 30% of 48,000,000 |
| Less withholding credits | (8,000,000) | Certificates on the TRA ledger |
| Less four instalments of 1,750,000 | (7,000,000) | Paid on the quarter dates |
| Balance due by 30 June 2027 | 936,000 | Paid with the return |
Her March 2026 estimate put tax at TZS 15,000,000 and expected credits at TZS 8,000,000. She paid the TZS 7,000,000 difference in four instalments. The estimate was 94% of the correct tax, so the 80% test is met and no underestimate interest arises.
Now assume she files and pays two months late, on 31 August 2027. The penalty each month is the higher of 2.5% of TZS 936,000 (TZS 23,400) or TZS 100,000, so TZS 200,000 in total. Interest at 8.75% a year, compounded monthly, adds about TZS 13,700 if that rate still applied. Lateness costs about TZS 213,700 on a TZS 936,000 balance.
Her turnover also passes the TZS 200 million VAT threshold (F0242), so she must register for VAT and file monthly; see our guide to the VAT return. Her business licence renewal needs a tax clearance certificate (NEW-08-02), which depends on her returns and payments being current; see tax clearance in Tanzania.
What to do now
- Confirm residence. Count days and check the permanent home test for the year, because residence decides worldwide or source-only income.
- Map every income stream. List salary, business, fees, rent, interest, dividends and foreign income, and mark each as PAYE, final, non-final or untaxed.
- Choose the regime. Under TZS 200 million of turnover, compare presumptive tax with tax on actual profit before opting out.
- Collect certificates. Ask each client who withheld 5% for the certificate, and match it to the TRA ledger.
- File the estimate by 31 March. Aim for at least 80% of the expected tax, and revise it if income moves.
- Pay each instalment on time. Generate a control number for each quarter and keep the receipts.
- Close the books. Prepare the accounts, attach them with the certificates, and file the return by 30 June.
- Check the ledger. Confirm every payment and credit is posted, and object within 30 days to any assessment you dispute.

How Zatra helps
Zatra prepares the individual file end to end. Our tax compliance desk registers the TIN, files the estimate and instalments and lodges the return. Our bookkeeping team keeps the records and prepares the accounts behind it. Where TRA audits or assesses, our audit and dispute desk prepares the response.
Costs come in two separate buckets. Tax, penalties and interest are paid to TRA at the official amount against TRA's control number; a TIN carries no prescribed fee (NEW-02-17). Zatra's professional fee is quoted on its own line and never mixed with them.
Zatra prepares and coordinates, but does not decide or guarantee any authority's outcome. Appeals to the Board or Tribunal, prosecution, search and seizure, and formal legal opinions go to an advocate.

Frequently asked questions
Do I file a nil return if my business made no sales this year?
If your TIN carries a business income tax registration, TRA will usually expect an estimate and a return each year. Filing nil avoids the fixed late-filing penalty of TZS 100,000 a month. If the business has closed, ask TRA in writing to update or close the registration.
Does selling my house go in the annual return?
Usually not. The gain on land or buildings is taxed as a single instalment at the time of sale (F0480), and PwC notes that income taxed this way falls outside the filing duty. Someone who buys and sells property as a trade is different: the profit is business income.
I work remotely for a foreign company from Dar es Salaam. Do I file?
Probably yes, if you are resident. A foreign employer with no Tanzanian payroll does not withhold PAYE, and the return exemption covers employment income from a resident employer. You would pay instalments and file a return. Confirm the treatment of your contract with TRA or an adviser first.
Can TRA reopen my return after I file it?
Yes. PwC's summary reports a five-year limit for TRA to adjust an income tax return, counted from the return due date. There is no limit where fraud, wilful neglect or serious omission is found. Keep records for at least that period.
What if I cannot pay the balance by 30 June?
File the return on time anyway, because the late-filing penalty is separate from interest. Then apply in writing to TRA for an extension of time to pay under section 66 of the Tax Administration Act. Expect interest at the statutory rate to run on the unpaid tax.
Do directors' fees go in my return?
Yes, if you are a non-full-time director. The company withholds 15% from your fees (F0185), and that withholding is not final. Put the fees in your return and claim the 15% as a credit, keeping the company's withholding certificate.
Can someone else file my return for me?
Yes. Section 28 of the Tax Administration Act gives a right to representation, and section 29 licenses tax consultants. You remain responsible for what is filed in your name, so review the return and the figures before it is submitted.
