What Late Corporate Tax Payment Can Cost

The unpaid balance is the exposure

The amount shown in EmaraTax and the amount shown in the bank are separate facts. The Federal Tax Authority says a Corporate Taxable Person must submit the return and remit Payable Tax within nine months from the end of the Tax Period. Filing records the liability. It does not prove that the bank settled it. Start with the Tax Period end date, the return acknowledgement, the payable-tax line and the bank value date before discussing penalties.

Cabinet Decision No. 129 of 2025 changed the administrative penalty schedule, and the FTA says it took effect on 14 April 2026. For unsettled Payable Tax, the current rule is 14% per annum for each month or part of a month, beginning the day after the payment due date. Do not reuse an older penalty calculator without checking the issue date and the legal instrument behind it.

An owner at this point should open the actual tax account, not rely on a calendar reminder. The return acknowledgement, the payment instruction and the bank settlement record answer different questions. Put them in one folder named for the Tax Period. If one item is missing, record that gap before calculating anything, because an assumed payment date can produce a false sense that the liability is closed.

• Return acknowledgement and payable-tax line.
• Tax Period end date in the working paper.
• Bank value date and settlement reference.
• Penalty schedule checked against its issue date.

Use the legal trigger in the estimate

For a practical estimate, calculate from the unsettled principal and mark the exact monthly trigger. Example only: if the principal is AED 100,000, the annual rate is 14%, and one monthly period is counted, the arithmetic is AED 100,000 x 14% ÷ 12 = AED 1,166.67. The figure is an estimate for planning, not a substitute for matching the FTA assessment and payment record.

Part-month wording matters. The official penalty table says the charge applies for each month or part thereof, from the day following the payment due date and on the same date monthly thereafter. That means the first question is not how many whole calendar months have passed. It is whether the unsettled amount crossed the trigger and what the recorded payment date was. Keep the calculation tied to those documents.

Do not round the planning figure to a whole amount and present it as an assessment. Preserve the principal, rate, period and formula in the working paper. If the FTA account shows a different balance, use that account and ask why the difference exists. A calculation that can be recreated is more useful than a confident total with no source trail. The old 2% plus 4% monthly method is not the current rule.

The bank trail decides what cleared

Payment status is proved by the bank advice, not by a screenshot of an instruction waiting for release. Match the EmaraTax liability to the transfer reference, bank debit date, beneficiary account and settlement confirmation. If the transfer was rejected, returned or split, keep each record. A partial payment changes the unsettled balance, so the review should show which amount remained open after every payment event and which date supports that conclusion.

If the return was filed by an adviser, obtain the submitted acknowledgement and the computation used to produce it. Then compare that file to the bank statement and the FTA account. The most useful working paper is a short timeline with due date, filing date, payment instruction, bank settlement and any FTA notice. It lets the owner see the exposure without rebuilding the case from email.

An amount may be filed but still unpaid, or paid but not yet matched in the account. Those states need different evidence. The payment reference proves what was attempted. The bank settlement proves what cleared. The FTA account confirms what was credited. Record each state instead of treating every green banking status as final.

• Transfer reference and bank debit record.
• Settlement confirmation for each payment.
• FTA account balance after payment.
• Timeline of filing, due date and payment events.

Keep the return error separate

Once a mismatch appears, separate the work into principal, filing correction and penalty review. Do not bury an incorrect tax figure inside a payment discussion. Confirm the return version, identify the line that changed, preserve the original submission and prepare the corrected calculation from the same ledger. The FTA remains the authority for the account, so the file should distinguish what was submitted from what is now proposed.

Send the reviewer the tax computation, return acknowledgement, payment evidence, bank statement for the relevant period and any FTA correspondence. If the amount was paid through more than one transfer, supply all references. A clear file lets the business decide whether it needs a correction, a payment reconciliation or a written question to the FTA. It also stops a late payment from being treated as an unexplained bookkeeping difference.

Do not delete the first working paper when the number changes. Version the computation, note the reason for the change and retain the supporting entry. This matters when the business has switched advisers or accounting software during the period. A reviewer can then trace the correction without guessing which figure management intended to defend. The mistake we see most is treating a changed return and an unpaid balance as one problem. They need separate workpapers.

• Original return and later working version.
• Line-by-line reason for any change.
• All bank references for split payments.
• FTA correspondence kept with the calculation.

Clear the principal before the argument

In our view, settle the principal before spending time debating the penalty calculation, unless the principal itself is disputed. The reason is practical. Every day an amount remains unsettled can change the exposure, while a clean payment record gives the reviewer something definite to test. Put the bank evidence beside the return first. Arguments about labels can follow.

The FTA announcement confirms the rate and the timing trigger, but it does not set out an answer for every payment-processing event, such as a transfer rejected by the bank and re-submitted later. That boundary is real. For that case, the bank rejection notice, re-submission record and settlement confirmation matter more than a generic calculator. If the records conflict, ask the FTA or a qualified adviser.

Address the decision point directly. If payment is due or already late, gather the four records today: the filed return, the liability account, the bank trail and the FTA correspondence. If they agree, you can quantify the position. If they do not agree, pause the conclusion and resolve the mismatch before calling the account clear.

• Principal disputed or confirmed.
• Bank evidence placed beside the return.
• Processing exception marked for review.
• Unresolved conflict sent to the FTA.
