Giving your tax adviser access in Nigeria
How a Nigerian business gives its tax adviser access on Rev360 and in Achekam without sharing passwords, sets what the adviser can do, and ends it.

In many Nigerian businesses, the tax portal password lives on a sticky note, in a WhatsApp chat with the consultant, or in the head of a bookkeeper who left two years ago. Everyone who might need to file has it. Nobody can say who filed what. And when the relationship with the adviser ends, the password usually stays with them.
There is a better way on both sides of the work. The NRS's Rev360 portal gives advisers access of their own, and Achekam lets you appoint your adviser's firm into your books with a level of access you choose. This article covers both, and how to end the arrangement properly when the time comes.
Role-based adviser access on Rev360
The NRS launched Rev360 on 30 April 2026 to replace TaxPro Max, and it gives tax advisers role-based access without sharing credentials. Your adviser acts for your business under their own identity, and your password stays yours.
The NRS describes the adviser's side on its Tax Consultants Portal page: how tax practitioners register as consultants using their own Tax ID, add client profiles, and file returns, pay taxes and manage clearance certificates on clients' behalf. Send your adviser the link and ask them to add your business as a client profile rather than asking you for your login.
The benefit is not only security. When each person files under their own access, the portal's record shows who did what, which is exactly what you want when a filing is questioned.
Keep your own access, too. Role-based access for the adviser does not mean handing the portal over. Someone in the business should still be able to log in, see what has been filed and paid, and download receipts without waiting for the adviser. If the only person who can see your tax position on Rev360 works for another firm, you have swapped one dependency for another.
Appointing your firm in Achekam as tax practitioner
If your books are in Achekam and your adviser's firm uses Achekam too, appoint the firm from your own workspace. You find it by its Achekam address or firm code, and choose its role: accountant, auditor, tax practitioner, payroll provider or adviser. For a tax adviser, the tax practitioner role says what the firm is there to do. The firm then accepts or declines.
The appointment links the firm to your books; it does not give anyone your password. Each person at the firm signs in as themselves.
Choosing the access level
When you appoint the firm, you also give it an access level, and that decides what its people can do in your books. Two of the levels, for example:
| Access level | What the firm's people can do |
|---|---|
| Bookkeeping | Work in the accounting, but not change your users, settings or payment gateways |
| Review | Read only |
For a tax adviser who prepares returns from your books, bookkeeping access lets them post the adjustments a return needs. For an adviser who only reviews figures your own staff prepare, review access is enough. Choose the lowest level that lets the firm do the job.
Filing permission for named people only
Recording that a Nigerian return has been filed is a separate matter from working in the books. In Achekam, no role receives the Nigerian filing permission by default; it is granted to named people only. Decide who those people are: someone in your business, a named person at the adviser's firm, or both, and write it down.
The reasoning is sound. A record that says "this return reached the NRS" drives deadlines, penalties and clearance applications, so the people who can make that record should be chosen deliberately.
Your sign-in rules apply to the firm too
If your business has set an IP allowlist or two-factor sign-in rules, a firm member opening your books must meet them. The firm does not bring its own, looser rules into your workspace. If you require two-factor sign-in from your own staff, the adviser's staff face the same requirement when they work in your books.
Ending the appointment cleanly
Either side can end the appointment. When it ends, the firm loses access, and the books stay with your business. There is no managed handover between an old firm and a new one: you end one appointment and invite the new firm. The way that works in practice is covered in changing accountants: your books stay with you.
Ending the Achekam appointment does not touch Rev360. Remove the outgoing adviser's access to your business on the portal too, and if a password was ever shared before you moved to role-based access, change it.
A checklist for setting up an adviser
- Ask the adviser to register on Rev360 as a consultant and add your business as a client profile.
- Stop sharing your own Rev360 login, and change the password if it was shared.
- Appoint the adviser's firm in Achekam as tax practitioner.
- Give the lowest access level that lets them do the work.
- Name the people who may record filings.
- Confirm the firm's people can meet your sign-in rules.
- Note in your files the date access was given, and to whom.
Once the adviser files under their own access, every payment still needs its reference and receipt recorded; see recording a Nigerian tax payment with its RRR. For the portal itself, read Rev360: the NRS portal that replaced TaxPro Max.
General guidance only, not advice on your own circumstances. Tax and payroll rules change: check the current position with the authority or your adviser.
