How to Compare VAT Systems

Compare VAT systems by what actually affects margin — standard rate, B2B vs B2C exposure, and EU OSS.

Last updated:

Quick answer

VAT only bites where you have VAT-bearing B2C revenue; compare standard rates for B2C exposure and weight EU OSS for cross-border B2C — in B2B reverse-charge flows VAT is often neutral.

Key takeaways

  • Standard VAT rate matters for B2C; B2B reverse-charge often makes it neutral.
  • EU OSS collapses cross-border B2C VAT into one return.
  • Reduced rates and thresholds are not modelled — treat rates as a screen.

Who actually bears VAT

For B2B sales under reverse charge, VAT is frequently a wash. For B2C, the standard rate flows almost directly into price competitiveness or margin. Compare jurisdictions on the dimension that matches your revenue mix rather than the headline rate in isolation.

The EU OSS lever

Selling B2C across the EU without OSS means many national registrations; with OSS it is a single return. For EU-facing B2C, OSS availability is often more valuable than a 1–3 point rate difference.

Decision framework

FactorGuidance
Revenue mixB2C → rate matters; B2B reverse-charge → often neutral.
EU OSSWeight EU/EEA membership for cross-border B2C.
CaveatsReduced/zero rates and thresholds need separate checking.

Turning this into a decision

  1. Shortlist with the ranking

    Use the related ranking to narrow candidates by the factor this decision turns on.

  2. Model your own numbers

    Run the related calculator on your figures — decide on effective, not headline, terms.

  3. Validate on the country profile

    Confirm the one or two decisive factors (payments, banking, formation) on each candidate's profile.

  4. Keep personal residency separate

    Company jurisdiction is not personal tax residency — take that to a qualified cross-border advisor.

What founders usually optimize for

  • Low standard rate where B2C exposure is real
  • OSS simplicity for EU B2C
  • Accurate revenue-mix framing

Common mistakes

  • Treating VAT rate as universally important including pure B2B
  • Ignoring OSS for EU B2C
  • Assuming the standard rate applies to all supplies

Data limitations

  • Estimates use headline rates; your effective rate depends on deductions, incentives, timing, and local taxes specific to your business.
  • Payment-provider availability (Stripe, PayPal, Wise) reflects the most recent review and may change over time.
  • Company-jurisdiction data does not model personal tax residency, which is individual and treaty-dependent.
