Compliance & Tax Filing Disclaimer

Last updated: 8 September 2026

Read this before relying on BusinessOS for regulated tax filing. BusinessOS is a bookkeeping and invoicing tool — not a replacement for a licensed accountant, and not (yet) a direct e-filing integration with any national tax authority.

What BusinessOS provides

Professionally formatted invoices with the fields your country's tax authority requires (VAT/GST/sales-tax rate, buyer & seller identifiers, sequential numbering, itemized lines)
Configurable tax rates for your region (5% UAE, 15% Saudi, 20% UK, 10% Australia, 5-28% India, 19% Germany, 20% France, and more)
Bookkeeping records — income, expenses, customers, products, inventory
Standard financial reports — P&L, balance sheet, cash flow, tax summaries
PDF export of invoices for record-keeping
CSV export of records for hand-off to your accountant or bookkeeping software
Zero-knowledge encryption of your data on your device
Full offline operation for daily use

What BusinessOS does NOT do

BusinessOS does not perform any of the following. If you need any of these, you must use a certified tax filing service or engage an accountant.

Direct real-time submission of invoices or returns to any tax authority
Automatic tax filing on your behalf (annual returns, quarterly VAT returns, etc.)
Legal or accounting advice for your specific business situation
Guarantee of compliance with every rule that may apply to your specific business type, jurisdiction, or industry
Payroll processing or employer tax filing
Bank reconciliation via direct feeds (planned for a future release)

Country-specific compliance notes

🇸🇦 Saudi Arabia — ZATCA

Provided: Invoice formatting that meets ZATCA Phase 1 (Generation Phase) requirements — 15% VAT, TRN fields for buyer and seller, sequential numbering, bilingual Arabic/English layout, structured PDF export.

Not provided: Direct integration with ZATCA's FATOORAH platform for Phase 2 real-time clearance. Phase 2 requires a cryptographic certificate from ZATCA and API integration, which BusinessOS does not currently offer.

Who this affects: If your business is required to comply with ZATCA Phase 2 (typically businesses above SAR 40M in annual revenue, or in later waves), you will need a certified Phase 2 solution alongside BusinessOS.

🇦🇪 United Arab Emirates — Federal Tax Authority

Provided: Invoice formatting compatible with FTA VAT rules — 5% VAT, TRN fields, sequential numbering, bilingual layout.

Not provided: Direct submission of VAT returns via the FTA EmaraTax portal. You (or your tax agent) must file your VAT returns manually or via a certified integration.

🇬🇧 United Kingdom — HMRC & Making Tax Digital

Provided: Bookkeeping structure compatible with MTD requirements — categorized income and expenses, VAT-inclusive/exclusive amounts, digital record retention.

Not provided: Direct submission to HMRC via the MTD API. MTD-compatible submission requires HMRC developer registration and approval, which BusinessOS has not yet completed.

🇺🇸 United States — IRS

Provided: Expense categorization suitable for Schedule C preparation, income tracking, invoice numbering.

Not provided: Direct e-filing of federal or state tax returns, 1099-NEC electronic filing, sales tax nexus tracking, or state sales tax return submission. You (or your CPA) must file all returns yourself using an IRS-approved e-file provider.

Your responsibility as a user

By using BusinessOS you acknowledge and agree that you (or your appointed accountant / tax agent) remain responsible for:

Filing all applicable tax returns with the correct tax authority by the correct deadline
Verifying that the invoices and records you generate with BusinessOS meet the specific rules applicable to your business type and location
Selecting an appropriate tax rate for each invoice
Maintaining any additional records your jurisdiction requires (bank statements, receipts, contracts, etc.)
Any real-time e-invoicing or e-reporting integrations required by your country's tax authority
Consulting a licensed accountant or tax advisor for compliance-critical decisions

No warranty of compliance

BusinessOS is provided "as is". While we make reasonable efforts to keep our formats and calculations aligned with common tax authority requirements, we make no legally binding warranty that any invoice, report, or record produced by BusinessOS will be accepted by any specific tax authority, court, or auditor. Tax rules change; we may not update the software in time for every change.

What's coming next

The following country-specific features are on our roadmap. We will update this page as each ships:

ZATCA Phase 1 QR code generation for Saudi simplified invoices
Country-aware field labeling (GSTIN in India, USt-IdNr in Germany, SIRET in France, etc.)
CGST/SGST/IGST split logic for India
HSN/SAC code fields on line items
MTD-compatible CSV export format for UK
1099-NEC year-end summary for US contractors
BAS-ready GST report structure for Australia

Real-time submission integrations (ZATCA Phase 2 clearance, HMRC MTD API, IRS e-file, ATO SBR, Chorus Pro, Verifactu) are longer-term and require partnerships, developer certifications, and regulatory approvals that we have not begun. They are not on our short-term roadmap.
