Rev360 Nigeria: What Businesses Should Prepare Before Filing

Rev360 is live.

That does not mean the best next step is to open the portal, click everything that looks clickable, and hope your records somehow arrange themselves.

A tax portal is only as useful as the information you bring into it.

Think of it like cooking: Rev360 may be the kitchen, but you still need the ingredients. If your sales records are in one spreadsheet, expenses are hiding in WhatsApp messages, and nobody remembers the company email password, the portal cannot perform magic.

This guide explains what Nigerian businesses should prepare before using Rev360, without drowning you in tax jargon.

Information reviewed on 14 June 2026. Rev360 is being introduced in phases, so portal screens and availability may change.

Quick answer

Before you begin a filing or payment process on Rev360, confirm these eight things:

1. You know whether you are an existing TaxPro Max taxpayer or a new taxpayer.
2. You can access the email address or phone number connected to your tax records.
3. Your Tax ID and business details are correct.
4. You have reviewed previous filings, receipts, balances and credits.
5. Your current sales, expenses, VAT, WHT and payroll records are organised.
6. You have estimated the tax figures before entering them.
7. You know who is authorised to manage the account.
8. You have confirmed the deadline that applies to the obligation.

That is the practical version.

Do not begin with passwords and portal buttons. Begin with your records.

What is Rev360?

Rev360 is the taxpayer self-service platform introduced by the Nigeria Revenue Service, or NRS.

It officially went live on 30 April 2026 as part of the transition to a more integrated digital tax-administration system.

The rollout is happening in phases, which means two taxpayers may not always see the same options at the same time.

The portal currently presents services connected to areas such as:

• taxpayer profile management
• self tax filing
• payments
• e-invoicing
• tax-clearance certificates
• tax wallet and balances
• refunds
• assessments and compliance information

The official portal is the official NRS taxpayer self-service portal.

Always confirm the domain before entering any account information.

TaxCalc.ng is an independent tax-preparation platform. It is not operated by NRS and does not issue Rev360 credentials.

Who should pay attention to Rev360?

Rev360 matters to more than accountants working inside large companies.

You should pay attention if you are:

• a registered company
• a founder or small-business owner
• a finance, payroll or HR professional
• a tax consultant managing client records
• an existing TaxPro Max user
• a new taxpayer trying to register
• responsible for company filing, payment or tax-clearance processes

The exact workflow may differ depending on the taxpayer category and the stage of the phased rollout.

That is why preparing first matters.

---

1. Know which taxpayer path you are taking

The first question is not “What is my password?”

It is:

Am I already in the tax system, or am I registering for the first time?

Existing TaxPro Max taxpayers

If your business previously used TaxPro Max, follow the existing-user or account-recovery path presented on the official Rev360 portal.

Do not create a brand-new taxpayer profile simply because you cannot remember the old login details.

If you are unsure which button applies, read the Rev360 login and registration guide before starting a new registration.

You may already have:

• an existing taxpayer record
• previous filings
• payment history
• tax credits
• assessments
• receipts connected to the account

Creating duplicate records can cause more confusion than it solves.

New taxpayers

If the business has never completed the relevant registration, follow the new-account process displayed on the official portal.

The registration portal separates taxpayer categories, including corporate, individual, non-resident and free-trade-zone routes.

Choose the category that matches the taxpayer. Do not select a random option just because it allows you to continue.

2. Confirm access to the registered email and phone number

This sounds simple until the company email belongs to:

• a former employee
• an accountant who no longer works with the business
• a director who has forgotten the password
• an old Gmail account nobody has opened in two years
• an agency that registered the company and disappeared

Before you need an OTP or recovery link, confirm:

• which email address is connected to the taxpayer record
• who controls the inbox
• whether the inbox can still receive messages
• whether the registered phone number is active
• whether the authorised company representative is still available

Do not wait until filing day to discover that the recovery email belongs to someone who left the company in 2023.

---

3. Verify your Tax ID and business details

Your taxpayer identity is the foundation of the process.

Check that you have the correct:

• legal business name
• Tax ID or existing TIN reference
• CAC registration details
• business address
• taxpayer category
• contact information
• accounting period, where relevant

A small spelling difference can become a large headache when records need to match across different systems.

If you are still confused about TIN and Tax ID language, read Tax Identification Number in Nigeria (2026).

The important thing is not only having a number written somewhere. The number should belong to the correct taxpayer record and match the business you are trying to manage.

---

4. Review your old records before creating new ones

Do not treat Rev360 like a completely empty notebook.

Before entering a new filing period, review what you already have:

• previous tax returns
• payment receipts
• tax-clearance certificates
• withholding-tax credit notes
• assessments
• outstanding balances
• refund requests
• correspondence from the tax authority

If historical information appears on your profile, compare it with your own records.

Ask:

• Does the balance look familiar?
• Are previous payments reflected?
• Are expected credits available?
• Is a filing period missing?
• Does the taxpayer name match exactly?
• Are there obligations you thought had already been resolved?

Take screenshots or save relevant records where appropriate, but do not share portal passwords or OTPs with anyone.

Where something looks wrong, investigate it before adding another layer of transactions.

5. Organise the current period properly

This is where many businesses discover that their tax problem is really a record-keeping problem wearing a tie.

You should be able to find the relevant figures without searching five phones and calling three former staff members.

Depending on the obligation, organise:

Sales and income records

Keep:

• sales invoices
• receipts
• bank inflows
• credit notes
• cancelled transactions
• income schedules

Your bank balance is not automatically the same thing as taxable income.

Expenses

Organise expenses into sensible categories and keep supporting documents.

Examples may include:

• salaries and wages
• rent
• utilities
• software subscriptions
• professional fees
• logistics
• equipment
• marketing
• business travel

An expense written as “transfer to Kunle” is not a useful accounting category.

VAT records

Where VAT applies, separate:

• taxable sales
• exempt or zero-rated supplies where relevant
• output VAT
• eligible input VAT records
• VAT invoices
• previous remittances

VAT collected should not be casually treated as extra profit available for spending.

Withholding tax records

Keep records of:

• deductions made
• deductions suffered
• credit notes
• transaction dates
• counterparties
• relevant contracts or invoices

A WHT credit that cannot be connected to a transaction may be difficult to reconcile later.

Payroll and PAYE

For payroll-related work, keep:

• employee information
• gross pay
• eligible deductions
• PAYE calculations
• pension and other payroll deductions
• payment and remittance records

PAYE is not company income tax, and company income tax is not VAT. Keep the workflows separate.

6. Estimate the numbers before entering the portal

Rev360 is the official administration platform.

That does not mean you should use the filing screen as your rough-work notebook.

Calculate and review your figures before entering them.

Why?

Because when you prepare first, you can:

• spot unusual numbers
• correct missing records
• compare periods
• understand what created the liability
• plan for payment
• explain the figures to a director, adviser or auditor

For business tax planning, use the Company Income Tax Calculator.

For payroll or personal PAYE, use the Personal Tax Calculator.

TaxCalc helps you estimate and understand your figures. It does not submit returns to Rev360.

A cleaner workflow is:

1. Organise the records.
2. Calculate the figures.
3. Review the result.
4. Confirm the deadline.
5. Complete the official process through the NRS portal.

---

7. Decide who is authorised to manage the account

A business tax account should not be managed like a shared Netflix password.

Know who is responsible.

That person may be:

• a director
• an internal accountant
• a finance manager
• an external tax consultant
• another properly authorised representative

The business should understand:

• who can log in
• who prepares the figures
• who reviews the figures
• who approves a filing or payment
• where supporting documents are stored
• what happens when the responsible person leaves

Do not casually send passwords or OTPs through group chats.

TaxCalc will never ask for your Rev360 password, OTP, BVN or portal credentials.

---

8. Confirm the deadline that applies

A perfectly calculated return submitted late can still create an avoidable problem.

Before filing, identify:

• the tax involved
• the period involved
• the filing deadline
• the payment deadline
• whether an extension or special rule applies
• who is responsible for completing the action

Do not assume every tax has the same due date.

You can use the Tax Deadline Calendar for orientation, but confirm the final requirement with the relevant tax authority or a qualified adviser.

---

A simple Rev360 preparation folder

You do not need a complicated document-management system to become more organised.

Start with one main folder, then give every document a sensible home.

The exact folder names are not sacred.

The goal is to stop storing important tax records under filenames such as:

Future you deserves better.

Common mistakes to avoid

Entering figures before reconciling them

A number being available does not make it correct.

Compare sales, bank records, invoices and previous returns before filing.

Mixing personal and company records

A founder's personal transfers should not automatically be treated as company income or expenses.

Separate the records properly.

Assuming a low tax bill means no compliance work

A company may have little or no tax payable and still need proper records, returns or supporting information.

Zero payable is not the same as zero responsibility.

Creating a new profile when recovery is the real issue

Existing taxpayers should first explore the sign-in or recovery paths shown on the official portal.

Sharing credentials carelessly

Nobody needs your OTP to “help you calculate tax.”

Calculations and account access are separate jobs.

Using an unofficial website

Check the domain carefully.

The official Rev360 portal promoted in this guide is:

selfservice.nrs.gov.ng

Frequently asked questions

What is Rev360 in Nigeria?

Rev360 is the Nigeria Revenue Service taxpayer self-service platform for managing federal tax-administration processes. It officially went live on 30 April 2026 and is being introduced in phases.

What is the official Rev360 website?

The official portal promoted in this guide is selfservice.nrs.gov.ng. Always check the domain before entering login details or other account information.

What should existing TaxPro Max users do?

Existing taxpayers should follow the existing-user, sign-in or account-recovery options displayed on the official Rev360 portal. Do not create a duplicate taxpayer profile simply because you cannot remember an old password.

Can TaxCalc file my Rev360 return?

No. TaxCalc helps with calculation, preparation, planning and record clarity. Final registration, filing, payment and account actions happen through the official NRS platform.

Does the TaxCalc readiness checker store my answers?

No. The Rev360 readiness checker does not store your individual answers in a database, cookie, local storage or session storage. It also does not ask for your Tax ID, BVN, password, OTP or financial figures.

Does completing the checklist mean my business is tax compliant?

No. The checklist only helps you prepare. It does not certify compliance, confirm filing accuracy or guarantee acceptance by the Nigeria Revenue Service.

Final word

Rev360 can make tax administration more digital, but digital does not automatically mean effortless.

The businesses that will have the smoothest experience are not necessarily the ones with the fanciest accounting software.

They are the ones that know:

• which taxpayer record they are using
• where their documents are
• how their figures were calculated
• who is authorised to act
• what deadline applies
• when to ask for professional help

Do not rush into the portal with guesses.

Prepare the records. Check the numbers. Then file with a clearer head.
