About this Product
Microsoft Dynamics 365 Business Central has no built-in, country-aware withholding tax engine outside a handful of localizations, so most tax teams manage WHT in spreadsheets and post manual journals — error-prone and audit-unfriendly. This extension fixes that.
What it is. A custom AL extension built to your exact WHT rules, installed as a per-tenant extension on your Business Central environment (cloud SaaS or on-prem), not a generic AppSource download. ECOSIRE scopes the countries, rates, thresholds and certificate formats you need, builds the extension, deploys it through your admin center / Extension Management, and supports it.
How it works in BC. Table and page extensions add WHT setup to Vendor, Purchase, and Payment Journal pages. Event subscribers on document posting (e.g. OnAfterPostPurchaseDoc, payment application events) auto-calculate the withholding amount, post it to a dedicated G/L account, and write a WHT ledger entry — no manual journals. A configurable rate table keys WHT by country, vendor, nature-of-payment code and threshold, with vendor exemption certificates honored automatically.
Certificates and returns. Generate WHT certificates per vendor/period as Word/RDLC report layouts you can brand, plus period-end statutory return datasets exportable to Excel/CSV for filing. Data is exposed via the BC REST/OData API for Power BI dashboards and Power Automate flows, and a Job Queue entry can prepare period returns on a schedule.
Honest delivery. This is build-to-order. After purchase ECOSIRE confirms requirements, builds against your localization, installs on a sandbox for UAT, then promotes to production with a permission set and handover docs.

Frequently Asked Questions about Withholding Tax (WHT) Management for Business Central
Is this an instant AppSource download?
No. It is built to order. ECOSIRE develops the extension against your specific countries, rates, certificate formats and Business Central localization, installs it as a per-tenant extension on your environment, and supports it. It is not a one-click AppSource install.
How long does delivery take?
Typical lead time is about one working week after requirements are confirmed, depending on the number of countries, certificate templates and the complexity of your exemption rules. We agree a firm timeline during scoping, deploy to a sandbox for UAT first, then promote to production.
How do ongoing support and updates work?
Each build includes a warranty window for defect fixes. Beyond that, ECOSIRE offers a support plan covering rate/threshold updates, certificate or return-format changes, compatibility with Business Central's twice-yearly major releases, and adding new countries as your obligations grow.
Does it work with Business Central online (SaaS) and on-premises?
Yes. It is delivered as a standard AL extension and works on Business Central online (cloud SaaS) and supported on-premises versions. On cloud it installs through the BC admin center / Extension Management; on-prem we deploy the .app to your service tier.
Will WHT data be available for Power BI and automation?
Yes. WHT ledger entries are exposed through the Business Central REST/OData API, so you can build Power BI reports, trigger Power Automate flows, or feed Dataverse. A Job Queue entry can also prepare period returns and certificate batches on a schedule.
What if a posted document is corrected after WHT is calculated?
The extension includes recalculation and reversal routines. When a source invoice or payment is corrected or cancelled, the related WHT ledger entries are reversed or adjusted so your G/L and certificates stay accurate and reconcilable.
