Lump‑sum and VAT — key rules

Lump‑sum is a PIT regime. VAT is separate and does not disappear when you choose lump‑sum. Below is a clear explanation of when VAT is mandatory, when exemption is possible and how it affects business decisions.

Start with the fundamentals: Lump‑sum — basics.

Lump‑sum and VAT — two different taxes

Lump‑sum regulates income tax. VAT concerns turnover on goods and services. That means you can:

• be on lump‑sum and not be a VAT payer (if you meet exemption conditions),
• be on lump‑sum and also be a VAT payer.

When VAT is mandatory

VAT becomes mandatory when:

• you exceed the statutory turnover limit for exemption,
• you provide goods/services excluded from exemption.

In those cases, lump‑sum does not remove VAT obligations.

When VAT exemption is possible

VAT exemption is possible if you stay below the statutory turnover limit and do not perform excluded activities. It simplifies accounting, but you cannot deduct VAT on purchases.

When being a VAT payer makes sense

VAT can be beneficial when:

• you have investments and want VAT deductions,
• your clients are businesses that expect VAT invoices,
• your activity has significant VAT‑bearing costs.

Common mistakes

• thinking lump‑sum “exempts from VAT”,
• not monitoring turnover against the exemption limit,
• choosing VAT exemption despite investment needs,
• confusing VAT rates with lump‑sum rates.

Short practical scenario

No numbers: A lump‑sum entrepreneur starts working with a large company that requires VAT invoices. They must register for VAT, while still settling PIT under lump‑sum.

VAT decision checklist

• verify whether your activity is excluded from VAT exemption,
• monitor turnover against the exemption limit,
• assess whether VAT deductions are needed,
• check client requirements (B2B/B2C),
• remember VAT and lump‑sum are independent regimes.
