Why Accounting in the UAE Changed in 2023

Before June 2023, your books were a record of the past. After June 2023, your books became evidence.

That single word is the whole shift. A record is something you keep for your own reference, and if it is imperfect, that is inconvenient rather than costly. Evidence is examined by someone else, measured against a standard, and used to reach a conclusion about you.

I stopped using accounting language to explain this years ago. Say accrual basis to an owner running on bank statements and instinct, and you have lost them. In my experience, the evidence framing lands, because it is accurate.

What the Law Actually Requires

Four separate obligations now sit on top of the same set of books.

• Corporate Tax. Taxable income starts from accounting profit prepared under IFRS. Ministerial Decision No. 114 of 2023 permits IFRS for SMEs up to AED 50 million of revenue, and cash basis only up to AED 3 million.
• VAT. Businesses above AED 375,000 of taxable turnover charge 5% and file within 28 days of each tax period. Every input claim needs a valid tax invoice behind it.
• Record retention. Seven years from the end of the relevant tax period under Article 56, and fifteen years for real estate.
• Company and free zone obligations. The Commercial Companies Law requires records that accurately reflect financial position, and ADGM, Masdar City and KIZAD add their own audit requirements.

What Disorganised Books Actually Cost

A trading business came to me from Mussafah. The owner had run it for six years on reasonable turnover and was convinced it was barely breaking even. Within a month of separating personal expenditure and categorising transactions properly, the business turned out to be profitable.

He had been subsidising his personal life through the company account without realising it distorted his entire view of the business. Pricing and hiring decisions had been made against a financial picture that was not real.

The same blind spot shows up in cash. An owner sees AED 400,000 in the account and feels comfortable. Clean books show AED 180,000 owed on a VAT payment due in three weeks, AED 90,000 in a supplier invoice not yet presented, and payroll to cover from what remains. A bank balance check does not surface that.

Clean books used to mean the bank reconciled and the year-end filed without drama. Corporate Tax raised the standard, because the accounts are now the starting point of a return that has to survive examination. Five things carry most of that weight.

The Right Accounting Basis, Applied Consistently

Most Abu Dhabi SMBs in my client intake are on cash basis, often without knowing that is what it is called. Above AED 3 million of revenue that is not a stylistic choice, it is non-compliance.

The most common technical failure is timing. I ask an owner a simple question: when a customer pays a deposit before the work is done, when do you record it as income? Most record it when it hits the bank. Under IFRS, income is recognised when the performance obligation is satisfied, and the deposit sits as a liability until then.

On one fit-out contractor with eight years of trading, that single issue produced an opening balance sheet adjustment of just over AED 800,000. Deferred revenue that had never been recorded. There was no intent to misstate anything, and under the old reality it simply did not matter.

Personal and Business Expenditure, Genuinely Separated

Mixing the two is close to universal in owner-operated businesses in their first three to five years, and it is now expensive. Article 28 of Federal Decree-Law No. 47 of 2022 is unambiguous: expenditure is deductible only where incurred wholly and exclusively for the purposes of the business. How it was coded is irrelevant to that test.

On a mainland consulting firm with four years of pre-Corporate Tax trading, every element of the pattern my reviews now surface immediately was there:

• Two vehicle leases running through the company, one genuinely used for the business and one the owner’s personal car, because it was simpler that way.

• A portion of a residential fit-out coded as office expenses.

• Club memberships and family mobile contracts sitting in general overheads.

• A family holiday coded as a client entertainment trip.

None of it was malicious. It was the natural behaviour of someone who built a business when the distinction carried no financial consequence. Totalled across four years, the disallowable expenses pushed taxable income materially above what the management accounts had shown.

The arithmetic is what makes it land. AED 500,000 of disallowable personal expenses sitting in your accounts is AED 45,000 of Corporate Tax you were not expecting. At AED 1 million, and I have seen multi-year histories reach that, it is AED 90,000. Fixing it costs a fraction of either figure.

VAT That Reconciles to Your Corporate Tax Position

Above seven in ten of the new clients whose filing history crosses my desk carry at least one category of VAT error. Rarely dramatic individually. The cumulative effect is what catches people.

• Input tax claimed on blocked expenses. Article 53 of the VAT Executive Regulations blocks input tax on entertainment provided to anyone not employed by the business, including customers and shareholders. The invoice carries VAT, so it gets claimed. It is not recoverable.

• Output tax understated on advances. Under Article 25 of Federal Decree-Law No. 8 of 2017, the date of supply is the earliest of the triggering events, including receipt of payment. Businesses that collect a deposit upfront and account for VAT only on the final invoice have already missed the tax point.

• Zero-rating applied without the documentation. A transaction that felt like an export, without the evidence the FTA specifies, is a zero rate the business was not entitled to.

What makes this consequential now is the cross-reference. If declared revenue for VAT does not reconcile to declared income for Corporate Tax, that discrepancy sits in the data waiting to be queried. Reconciling the two is part of my month-end close.

One confusion worth clearing up, because I correct it constantly. Entertainment works differently under the two regimes. Input VAT on entertaining non-employees is blocked entirely, while Article 32 of the Corporate Tax Law allows 50% of qualifying entertainment expenditure as a deduction. Applying one rule to the other creates errors in both directions.

Records That Survive a Five-Year Look-Back

The FTA’s standard audit limitation is five years from the end of the tax period, extending to fifteen for evasion or failure to register. Corporate Tax records must be kept for seven years.

Failure to keep required records carries AED 10,000 under Cabinet Decision No. 75 of 2023, rising to AED 20,000 for a repeat within 24 months. That is the cheap part. The expensive part is being unable to support a position you already took on a filed return.

Invoicing Data That Will Pass Machine Validation

E-invoicing readiness is not an IT project. It is a business process project that happens to involve technology at the end.

My assessment looks at three layers. The technology, meaning whether the system connects to an Accredited Service Provider. The data on the invoices. The process by which invoices get created, approved and issued.

Most clients present well on technology. The vendors are building integrations and that part will get solved. Data and process are where the real problems sit.

A system does not read an invoice the way a person does. It validates against a schema. A missing supplier TRN, a VAT amount that does not reconcile, an inconsistent date format: the invoice fails and cannot be issued.

The single most consistent gap I find is buyer TRN capture. Business-to-business e-invoices require the buyer’s TRN, and very few Abu Dhabi SMBs systematically collect and verify TRNs from their customers today. The correct sequence is data first, then process, then technology. Businesses that start with the software will hit the data problems mid-implementation and run out of time.

Construction and fit-out businesses have the most chaotic books of any sector in my practice. Retention is the clearest example of why.

Most construction contracts hold back five to ten percent of the contract value until the defects liability period expires. I have yet to review a first-time construction client’s books where retention was tracked as a distinct asset. On AED 10 million of active contracts, that is AED 500,000 to AED 1 million of assets the business does not know it has.

One Abu Dhabi fit-out contractor came to me perpetually confused about his cash position. Commercial interiors, turnover in the AED 15 to 20 million range. When I built the project register, the retention picture across seventeen completed projects looked like this:

• AED 1.4 million in retention receivables accumulated and never formally tracked.

• Roughly AED 800,000 genuinely recoverable, which the owner did not know existed in any structured sense.

• AED 600,000 aged between eighteen months and three years across six contracts, of which my conservative assessment put around AED 150,000 as still recoverable.

• AED 450,000 written off, which required restating prior year positions and accepting that the business had been overstating its asset base for years.

The write-off conversation was difficult, though not because the owner resisted it. He was relieved to have clarity after years of vague awareness that something was wrong.

Then I put a process in place: reminders tied to each defects liability expiry, a standard release letter, and a monthly ageing review. Within eight months the business collected AED 620,000 of retention that had been sitting idle.

Managing retention informally is the equivalent of leaving a significant cheque on your desk and forgetting to bank it. Except some of those cheques expire.

Every engagement rests on one principle: the books must reflect the business before anything downstream can be right.

Bookkeeping and Ledger Maintenance

Transactions recorded daily or weekly, categorised against a chart of accounts built for your structure rather than a generic template, with supporting documents captured against each entry.

IFRS Financial Statement Preparation

Profit and loss, balance sheet and cash flow prepared under IFRS or IFRS for SMEs, depending on revenue. These are not filing documents. They are the starting point of your Corporate Tax computation, the basis of your audit, and what any bank will ask to see.

Backlog Reconstruction and Clean-Up

When the books are months or years behind, reconstruction comes first. I run it in three phases.

1. Reconstruction. Every bank statement, supplier invoice, customer invoice and contract pulled and rebuilt into a complete transaction picture. Four to six weeks for a business of ten to twenty employees where records are intact, up to three months where they are fragmented.
2. Adjustment. The IFRS treatments cash basis ignored: revenue recognition, accruals, prepayments and fixed assets. That last one catches people. A fit-out costing AED 300,000 expensed in year one should have been capitalised and depreciated over its useful life. Three to four weeks once the reconstruction data is clean.
3. Validation. Restated statements stress-tested. Does restated revenue reconcile to the VAT returns filed for the same period? Does the balance sheet agree to the actual bank statements?

End to end, three to four months is realistic for a well-documented business of that size, and six months where records are poor. I would rather say that upfront than overpromise. More on backlog accounting.

Why this matters beyond tidiness: a first Corporate Tax return filed on an incorrect opening balance sheet compounds. Every subsequent year is built on a foundation that was wrong from the start.

Bank and Account Reconciliation

Monthly reconciliation against bank and card statements, with discrepancies, duplicates and unmatched items resolved before they cascade. It is also one of the first things examined in any compliance review.

Payables, Receivables and WPS Payroll

Invoices issued accurately, payments tracked against ageing schedules, overdue items flagged before they become write-offs. Payroll processed through the Wage Protection System, with gratuity provisions maintained and records aligned to MOHRE requirements.

E-Invoicing Readiness and Systems Setup

Invoicing data cleaned, the customer TRN database verified, the process standardised, and only then the platform connected to an Accredited Service Provider. In that order, the deadline is manageable.

Where the work connects to tax, it runs through corporate tax services and VAT compliance. Smaller operations suit small business accounting, and businesses replacing an internal finance function suit outsourced accounting.

The most important factor in platform selection is not the software. It is the person using it daily.

I have seen immaculate books on QuickBooks kept by a disciplined bookkeeper, and a complete mess on Xero. The platform creates the environment, it does not create the discipline.

Disclosure: I have a commercial relationship connected to Wafeq through PocketLedger. I have kept the comparison above as even-handed as I would for any platform, but you should know that connection exists.

The right question is not which platform is best. It is which one will be used correctly, consistently, and with enough oversight to catch errors before they compound.

Five steps, in this order, because each one depends on the last.

1. Initial assessment. I review your records, software and compliance status to establish whether you need optimisation, a historical clean-up, or a new structure built from scratch.
2. Onboarding and system setup. The platform is configured with a chart of accounts built for your business, documentation workflows and banking integrations.
3. Backlog clean-up, where needed. Historical records reconstructed, opening balances established, overdue filings prepared.
4. Ongoing recording. Transactions captured daily or weekly against your chart of accounts, with documentation that meets UAE retention requirements.
5. Month-end close. Reconciliations, adjusting entries and balance verification, so nothing is computed off an unreconciled ledger.

Five things I tell every client, drawn from what goes wrong most often.

• Do a twelve-month bank reconciliation first. Not a cleanup, not a software subscription. Match every transaction on every statement to an entry in the books and list what does not match. It tells you where you are, what is missing and what comes next, and it needs no knowledge of IFRS to start.

• Get personal spending out of the company account today. Every dirham of personal expenditure sitting in the accounts is disallowable under Article 28 and inflates taxable income with no offsetting benefit. The habit is cheap to break now and expensive to unwind across four years of history.

• Reconcile VAT to Corporate Tax before you file either. Declared revenue for VAT and declared income for Corporate Tax should tie. Where they do not, find out why before the FTA does, because that discrepancy sits permanently in the data.

• Use voluntary disclosure while it is still your choice. Under Cabinet Decision No. 129 of 2025, in force from 14 April 2026, a disclosure made before an audit notice costs 1% per month of the tax difference. An error the FTA finds instead carries a fixed 15% plus late payment at 14% per annum. The cost of disclosing is bounded. The cost of waiting is not.

• Build the project register before the ledger, if you contract. Every active and recent contract, original value, variations, invoiced, collected, retention held, and estimated completion. Without it you are not doing construction accounting, you are guessing with a spreadsheet.

E-invoicing is the development Abu Dhabi businesses are least prepared for, and the technical rollout is the least interesting part.

Once every transaction is reported digitally at the point of issuance, the gap between what you invoice, what you declare for VAT and what you report for Corporate Tax closes. Reconciliation that used to require a manual audit becomes an automated comparison. The data becomes the return.

The businesses most exposed carry informality in how they invoice. Cash transactions that generate no invoice, invoices issued below the full consideration received, related-party billing at non-arm’s-length amounts. None of that is invisible today, it is simply not surfaced systematically. E-invoicing surfaces all of it.

Three things worth doing before the pilot turns into a mandate:

1. Review what actually happens when you invoice, not what the policy says. That review has to happen before go-live, because afterwards the pattern is already in the system.
2. Document your related-party transactions. Intercompany billing becomes fully visible, and exposure that is theoretical today becomes certain to surface. Detail on transfer pricing.
3. Correct known VAT errors now. Errors self-corrected before e-invoicing went live read as a compliance journey. Errors that continued afterwards read as a compliance failure.

What stops most owners making the call is not cost or time. It is fear of what someone will find when they look.

In ten years of UAE practice, no set of books has crossed my desk that was too far gone to fix. Sole traders working out of a single messaging thread, family groups with fifteen years of entangled finances, entities that have never filed a return.

The engagement I think about most was a family-owned building materials importer, fifteen years of trading. The owner wanted to bring his son in as a partner. They needed a valuation and had no reliable financial statements to base one on.

Five months of reconstruction, IFRS restatement, a fixed asset register and a VAT reconciliation later, the business had audited accounts for the first time. The valuation came out higher than expected, because nothing had ever been capitalised. The son bought his stake on a number both parties trusted.
