cifraHQ computes the 50% and 100% ITBMS withholding on every supplier invoice, issues monthly certificates to your suppliers, and generates Form 4331 ready to upload to e-Tax 2.0 by the 15th.
Form 4331 is Panama's Sworn Declaration of ITBMS Withholding. Designated withholding agents must file and pay it monthly. It is not a new tax: it is a collection mechanism where the buyer withholds part of the ITBMS on the supplier's invoice and remits it directly to the tax authority.
The DGI designates withholding agents, with Large Buyers as the main category, plus sector-specific designations and entities making cross-border payments.
Form 4331 is due on the 15th of the month following the withholding period. cifraHQ pre-generates the draft 5 days in advance and alerts the compliance owner if any invoices remain unclassified.
Sworn Declaration of ITBMS Withholding
cifraHQ applies the correct percentage on every supplier invoice based on the DGI designation, the type of transaction and the supplier's origin.
From supplier-invoice capture to monthly certificates and reconciliation against Form 430, the entire 4331 cycle stays inside the ERP.
When you record a supplier invoice, cifraHQ detects whether 50% local or 100% cross-border withholding applies, computes the base, and tags the transaction for reporting.
Generate the ITBMS withholding certificate per supplier in one click, ready to email or publish in the supplier portal as evidence for their tax credit.
Produce Form 4331 in the format e-Tax 2.0 expects, with tax base, invoiced ITBMS and withheld amounts for the period, without hand-built files.
The compliance dashboard shows the day-15 deadline with severity indicators and notifies the owner if any invoices are still unclassified or missing withholding.
cifraHQ cross-checks 4331 against Form 430 for the same period: withheld amounts appear as credits in the monthly ITBMS report, with no orphan entries or manual journals.
Every 4331 line ties back to the supplier invoice, supplier record, journal entry and user, with permanent history for DGI audits and internal reviews.
From supplier invoice entry to a filed Form 4331, with no parallel spreadsheet and no rework.
Turn on the ITBMS withholding module, mark the taxpayer as Large Buyer where applicable, and load any specific DGI designations. cifraHQ applies the correct rate from the next invoice on.
Receive e-invoices or post manual documents normally. The system separates the tax base, invoiced ITBMS and withholding to be practiced.
At month-end, cifraHQ consolidates withholdings, drafts Form 4331 and produces the per-supplier certificate. The owner reviews and approves before day 15.
Export Form 4331 in the format DGI expects and upload it to e-Tax 2.0. The payment journal entry is posted and reconciled against Form 430 for the same month.
Form 4331 doesn't live alone: cifraHQ is the only ERP built in Panama that covers the full DGI compliance cycle from a single system.
When the DGI reviews withholdings, the agent has to be able to prove: what was withheld, from whom, against which invoice, when it was remitted and which certificate was issued. With cifraHQ, you export the full file from one place:
The questions that come up most in Form 4331 rollouts with clients in Panama.
It's the Sworn Declaration of ITBMS Withholding that DGI-designated withholding agents must file and pay monthly, within the first 15 days following the period declared.
Mainly Large Buyers (Grandes Compradores): companies with annual local purchases at or above B/.3,000,000.00. It also applies to taxpayers specifically designated by the DGI and to those making cross-border service payments.
50% of the ITBMS included on the local supplier's invoice or equivalent document. The Large Buyer remits that 50% directly to the DGI through Form 4331.
On remittances for professional services rendered from abroad, the agent withholds 100% of the ITBMS and declares it on the same Form 4331.
The 15th of the month following the withholding period. Filing and payment go through e-Tax 2.0.
Yes. The agent must issue a monthly certificate to each supplier for the withholdings practiced, so the supplier can document and claim the ITBMS tax credit.
They are separate but reconciled declarations. Form 430 reports the taxpayer's general ITBMS; Form 4331 reports what the agent withheld from suppliers. cifraHQ cross-checks them automatically so the numbers match month to month.
Mid-market companies in Panama no longer file 4331 by hand. Let's get a certified partner to roll it out without disrupting your month-end close.
