A small UAE manufacturer needs a bill of materials cost for each product, a work in progress and finished goods valuation at every month end, overhead absorbed on machine hours, recorded scrap, and a capex register. Those figures drive profit, so they drive Corporate Tax: the return for a December 2025 year end is due 30 September 2026, and missing records cost AED 10,000.
- You run a factory, fabrication workshop or production unit through a UAE company
- You buy raw materials and convert them into goods you sell
- Half-finished jobs sit on the shop floor at month end
- You are buying machinery or need audited accounts for a client, a bank or a certificate

Which UAE manufacturers need audit-ready books?
Every manufacturer operating through a UAE company needs books good enough to support a Corporate Tax return each year, and many also need audited financial statements. Whether an audit is a tax requirement depends on revenue and on any free zone 0% claim.
| Factory profile | Corporate Tax | VAT | Audit position |
|---|---|---|---|
| Mainland workshop, revenue under AED 3M | Files yearly; Small Business Relief electable for periods ending by 31 December 2029 | Registration mandatory above AED 375,000 of taxable supplies plus imports | No tax audit requirement at this size; banks or clients may still ask |
| Mainland factory, revenue AED 3M to AED 50M | Files yearly; 9% on taxable income above AED 375,000 | Registered; imported materials count toward the threshold | Not required for Corporate Tax below AED 50M revenue |
| Factory with revenue above AED 50M | Files yearly | Registered; e-invoicing provider by 30 October 2026 | Audited statements required under Ministerial Decision No. 84 of 2025 |
| Free zone manufacturer claiming 0% as a Qualifying Free Zone Person | 0% on qualifying income only | Designated zone rules can apply to goods, never to services | Audited statements required every year |
Free zone authorities set their own audit rules, which differ by zone and are not always published, so confirm yours with the authority. Our free zone audit requirements by zone summarises what is known.
How should a small factory cost its products with a BOM and machine hours?
Cost each product by adding three layers: materials from the bill of materials, direct labour from routing times, and factory overhead absorbed at a rate per machine hour. Set these as standard costs, then compare actual costs monthly and investigate the gaps.
Bill of materials and standard cost
A bill of materials lists every input and quantity for one finished unit, including packaging and expected wastage. Price each line at current purchase cost, including freight and customs duty on imported materials but excluding VAT you can recover. Review standards at least twice a year, or whenever steel, resin or aluminium prices move sharply.
| Cost layer for one steel cabinet | Basis | AED |
|---|---|---|
| Sheet steel, hinges, paint, packaging | BOM quantities at standard prices | 182 |
| Direct labour | 1.5 hours at AED 28 | 42 |
| Machine overhead | 0.8 machine hours at AED 65 | 52 |
| Standard cost per unit | 182 + 42 + 52 | 276 |
Setting a machine-hour rate
Add up the year’s factory overhead (power, maintenance, depreciation of production machinery, supervisor salaries, factory rent) and divide by the machine hours you expect to run. An illustrative workshop with AED 520,000 of overhead and 8,000 budgeted machine hours absorbs AED 65 per machine hour. Office rent and sales salaries stay out of the rate, because they are not production costs and cannot sit in stock.
How do manufacturers value WIP and finished goods, and record scrap and capex?
Value work in progress and finished goods at month end using the materials issued, labour booked and overhead absorbed on each open job, measured at the lower of cost and net realisable value. Record scrap and rework separately, and put machinery in a capex register rather than the expense lines.
WIP and finished goods stock
If a production order has used AED 38,000 of materials and 120 machine hours but is not finished on 31 December, that AED 45,800 (38,000 plus 120 x AED 65) is an asset, not a cost of the year. Skip it and profit is understated in one year and overstated the next. Corporate Tax starts from accounting profit, so the swing moves straight into your tax. Our inventory accounting guide covers valuation methods.
Scrap and rework
Build normal wastage into the BOM, and record anything above it as abnormal scrap in its own expense account with a scrap note signed by production. Sales of scrap metal or offcuts are income, and are taxable supplies once you are VAT-registered. Rework hours booked to a separate code show which products or machines are causing quality losses.
The capex register
See fixed assets accounting in the UAE for capitalisation and disposal entries.
| Register field | Purpose |
|---|---|
| Asset tag, description and location | Physical verification by the auditor |
| Supplier invoice, cost and installation costs | Correct capitalised amount |
| Date available for use | When depreciation starts |
| Useful life and method | Monthly depreciation charge |
| Disposal date and proceeds | Gain or loss on sale |
What is the month-end close routine for a small manufacturer?
A small manufacturer’s close runs in seven steps, finished within 10 working days, and it produces the stock, cost of sales and asset figures behind the quarterly VAT 201 and the annual Corporate Tax return on EmaraTax.
Post purchases and landed costs
Record raw material invoices with freight and customs duty added to material cost, and account for import VAT on the return as the importer. Match goods received notes to invoices.
Record material issues and production output
Post materials issued to each production order and finished units transferred to finished goods, using BOM quantities and standard costs.
Book labour and machine hours
Load timesheets and machine logs to production orders and absorb overhead at the machine-hour rate.
Value WIP and count stock
List open production orders with cost to date. Count raw materials and finished goods, or cycle count high-value items, and post differences.
Record scrap, variances and depreciation
Post abnormal scrap and rework, analyse price and usage variances against standard, and run depreciation from the capex register.
Reconcile and prepare VAT
Reconcile bank, supplier and customer balances. At quarter end, total standard-rated sales, exports and input VAT including imports, and file VAT 201 by the 28th of the following month.
Close the year for Corporate Tax and audit
At year end, finalise stock and WIP valuations, prepare the audit file if one is required, and file the Corporate Tax return within 9 months of year end.
What records does a factory need for auditors and the FTA?
A factory needs records that trace materials from purchase through production to sale, and assets from invoice to disposal, retained for 7 years for Corporate Tax.
- Supplier invoices, customs declarations and goods received notes
- Bills of materials and standard cost cards, with revision dates
- Production orders with material issues, labour and machine hours
- Month-end WIP listings and stock count sheets
- Scrap notes and rework logs signed by production
- Capex register with invoices, installation costs and disposals
- Sales tax invoices, delivery notes and export documents
- The overhead budget and machine-hour rate calculation
Which deadlines should a UAE factory owner diarise?
The first date on the list for December year end manufacturers is 30 September 2026, the Corporate Tax return and payment deadline; e-invoicing dates then shape your system choices through 2027.

| Obligation | Deadline | Detail |
|---|---|---|
| Corporate Tax return and payment | 30 September 2026 | December 2025 year ends |
| VAT 201 and payment | 28th of the month after each tax period | Includes reverse-charged imports |
| Tax invoice | Within 14 days of supply | AED 2,500 per invoice not issued |
| E-invoicing provider, revenue under AED 50M | 31 March 2027, go-live 1 July 2027 | No provider: AED 5,000 a month |
| E-invoicing provider, revenue AED 50M or more | 30 October 2026, go-live 1 January 2027 | Larger factories and groups |
| Small Business Relief | Periods ending on or before 31 December 2029 | Revenue up to AED 3M |
Provider selection is covered in our e-invoicing guide for SMEs.
What penalties can poor manufacturing records lead to?
Poor manufacturing records lead first to the AED 10,000 records penalty, and because stock errors change profit, often to an incorrect return and a tax assessment too. VAT penalties are from Cabinet Decision 129/2025 (in force since 14 April 2026) and Corporate Tax penalties from Cabinet Decision 75/2023 as amended.
| Failure | VAT | Corporate Tax |
|---|---|---|
| Not keeping records | AED 10,000 for a first violation | AED 10,000, rising to AED 20,000 on repeat |
| No Arabic translation on request | AED 5,000 | Records must be produced |
| Late return | AED 1,000; AED 2,000 repeat within 24 months | AED 500 per month in year one, AED 1,000 per month after |
| Late payment | 14% a year, calculated monthly | 14% a year, calculated monthly |
| Incorrect return | AED 500; AED 2,000 repeat | Tax difference can be assessed |
| Tax invoice or credit note not issued | AED 2,500 per case | Not applicable |
| No e-invoicing provider by the deadline | AED 5,000 a month | Not applicable |
A factory example of stacking: stock records that cannot support the year-end valuation (AED 10,000), a Corporate Tax return filed five months late (5 x AED 500 = AED 2,500) and three months without an e-invoicing provider after 31 March 2027 (3 x AED 5,000 = AED 15,000). Total: AED 27,500, before any tax the FTA assesses on corrected profit.

6 bookkeeping mistakes small manufacturers make
The mistake with the biggest tax effect in factory books is recording no WIP at month or year end, because every half-built job gets expensed and profit swings from year to year.
- No WIP at month end. Costs of unfinished jobs hit the income statement early, taxable income is wrong in two years, and an FTA review can produce an assessment plus an incorrect-return penalty.
- Standard costs never updated. Prices from two years ago value stock wrongly and hide real margins on every product.
- Office costs absorbed into stock. Admin salaries and showroom rent parked in inventory inflate assets and defer expenses you should have claimed.
- Machinery expensed on purchase. A AED 400,000 press charged in one month distorts profit and leaves no asset for the auditor to verify.
- Scrap sales kept in cash. Unrecorded offcut sales are unreported income and missing output VAT.
- Import VAT and duty mixed up. Customs duty belongs in material cost; import VAT belongs on the VAT return. Mixing them misstates both stock and the return.

How can a factory stay penalty-free and audit-ready?
A factory stays penalty-free and audit-ready by valuing stock and WIP monthly, not annually, and by reviewing the VAT treatment of imports and exports every quarter.
- Run all purchases and sales through business bank accounts, including scrap sales
- Reconcile bank and card accounts monthly, plus supplier and customer statements
- Close within 10 working days with WIP and stock valued
- Review standard costs and the machine-hour rate every six months
- Count stock at least quarterly and fully at year end with the auditor invited if needed
- Accountant review of import, export and reverse charge entries before each VAT return
- Keep production and stock records for 7 years, with Arabic translations available on request
- Appoint an e-invoicing provider well before your deadline
What if your factory's returns are late or the FTA has sent a notice?
File first and perfect later: rebuild the ledger from bank statements, supplier and customer invoices and customs records, agree opening stock and asset balances with a physical count, then submit every overdue return. Our catch-up bookkeeping guide explains the order, and our guide to a missed Corporate Tax deadline covers the first week.
Where earlier VAT returns missed import VAT or scrap sales, correct them by voluntary disclosure. Disclosing before an FTA audit notice costs 1% a month of the tax difference; after a notice it is 15% plus 1% a month.
If you dispute a penalty, request reconsideration within 40 business days, then go to the Tax Disputes Resolution Committee if needed. See how FTA reconsideration works.

Worked example: an Ajman fabrication workshop that never booked WIP
An illustrative Ajman metal fabrication company with a December 2025 year end had revenue of AED 5,200,000 and booked a profit of AED 310,000. It expensed all production costs as incurred, so AED 240,000 of work in progress on the floor at 31 December 2025 was never recorded, and books had not been reconciled for 12 months.
| Item | Working | AED |
|---|---|---|
| Profit as booked | Unreconciled ledger | 310,000 |
| Corporate Tax on booked profit | Below AED 375,000 | 0 |
| Add closing WIP not recorded | Open production orders at cost | 240,000 |
| Corrected taxable income | 310,000 plus 240,000 | 550,000 |
| Corporate Tax due | 9% x (550,000 minus 375,000) = 9% x 175,000 | 15,750 |
| Small Business Relief | Revenue AED 5.2M exceeds AED 3M | Not available |
| Records penalty if stock cannot be supported | First violation | 10,000 |
| Late return if filed 3 months late | 3 x AED 500 | 1,500 |
| Monthly bookkeeping for a year, from | 12 x AED 599 | 7,188 |
Filing on the booked figure would show no tax and understate the liability by AED 15,750, which the FTA could assess later together with an incorrect-return penalty. Booking WIP properly before filing costs the tax but avoids the rest. A catch-up is quoted as a fixed fee once we see production records.
In-house clerk, freelance accountant or firm for a small factory?
An in-house clerk can post invoices, but costing, WIP valuation and audit files need someone who understands production; small factories usually pair a clerk with an outside accountant.
| In-house clerk | Freelance accountant | Accounting firm | |
|---|---|---|---|
| Cost | A salary | Varies widely by hours | Fixed monthly fee; Paci from AED 599/month |
| BOM costing and WIP valuation | Rarely | Depends on manufacturing experience | Part of the monthly close |
| Audit file preparation | No | Sometimes | Prepared at year end |
| VAT on imports and exports | Basic | Varies | Reviewed quarterly |
| Best for | Posting and filing documents | Single-product workshops | Multi-product factories and audit cases |

What factory owners actually ask us
Our firm has had a TRN and Corporate Tax registration for years but never an audit. A client wants a tax residency certificate and our accountant says we may need audited accounts. What now?
The Ministry of Finance sets the document list for a tax residency certificate and it can include financial statements, so confirm the current requirements before applying. For Corporate Tax itself, audits are required above AED 50M revenue and for Qualifying Free Zone Persons. Either way, catching up starts with clean books kept for 7 years. Our tax residency certificate service can check the file.
We have just started trading with two B2B clients and need Zoho Books or similar set up. What should it cover from day one?
Set it up to issue tax invoices within 14 days of supply, track stock and production costs, and hold a fixed asset register. Plan for e-invoicing now: businesses under AED 50M appoint an Accredited Service Provider by 31 March 2027 and go live 1 July 2027, and having no provider costs AED 5,000 a month. Our Zoho Books vs Wafeq comparison helps you choose.
I am the sole owner of a SHAMS free zone LLC sending one or two invoices a month to clients abroad. What should a small accountant handle?
Corporate Tax registration and the annual return, even at zero revenue, a monthly check against the AED 375,000 VAT threshold, and books kept for 7 years. If you want free zone 0% instead of Small Business Relief, you need audited financial statements and adequate substance, and the two cannot be combined.
Our production system counts stock continuously. Do we still need a physical count at year end?
Yes, a system figure still needs to be proven. Count at year end, or run cycle counts through the year that cover all material stock, and post the differences. Auditors and the FTA both expect evidence that the stock on the balance sheet physically exists.
Frequently asked questions
What is cost accounting for a UAE manufacturer?+
Cost accounting works out what each product costs to make by combining materials from the bill of materials, direct labour and absorbed factory overhead. It sets the value of stock and work in progress on the balance sheet and shows margin by product. Because stock values change profit, it also shapes your Corporate Tax.
Do small factories in the UAE need audited financial statements?+
For Corporate Tax, audited statements are required when revenue exceeds AED 50M and for every Qualifying Free Zone Person, under Ministerial Decision No. 84 of 2025. Smaller mainland factories are not required to have one for tax, though banks, clients and free zone authorities may ask. Our audit checklist lists what auditors request.
How is Corporate Tax calculated for a manufacturing company?+
Start from accounting profit after correct stock, WIP and depreciation, make the tax adjustments, then apply 0% to the first AED 375,000 of taxable income and 9% above. Taxable income of AED 900,000 gives 9% x 525,000 = AED 47,250. Sector specifics are in Corporate Tax filing for small factories and UAE manufacturing Corporate Tax.
How should a factory account for imported raw materials?+
Add the purchase price, freight, insurance and customs duty to material cost, and treat import VAT separately on the VAT return, where registered importers generally account for it through the reverse charge. Our guide to VAT on imports and customs explains the entries.
When should machinery be capitalised instead of expensed?+
Capitalise equipment that will be used over more than one year, including delivery and installation costs, and depreciate it from the date it is ready for use. Small tools below your capitalisation threshold can be expensed. Keep each asset in the capex register with its invoice.
What does factory bookkeeping in Dubai typically include?+
It usually covers purchases and landed costs, production postings, stock and WIP valuation, the capex register and depreciation, bank and ledger reconciliations, quarterly VAT returns and year-end accounts for the Corporate Tax return. Confirm the quote includes WIP valuation, since that is the part most often left out.
