Build Czech Corporate Income Tax Return (DPPDP XML)

Skill: Convert a CIT computation into the Czech corporate income tax return

Region: Czech Republic (Česká republika) Category: Tax — Corporate (daň z příjmů právnických osob) Does: Takes a company's corporate-tax computation and assembles the DPPDP (přiznání k dani z příjmů právnických osob) XML for electronic filing through the Finanční správa EPO / MOJE daně (Daňový portál), submitted via data box / DIS+. Spec: Finanční správa DPPDP XML schema (dppdp_epo2.xsd, current version)

The corporate income tax return (přiznání k DPP) reconciles accounting profit/loss to the tax base through additions (položky zvyšující) and deductions (položky snižující), applies loss relief and tax reliefs, and computes the tax at the current CIT rate (21% from 2024). Line (řádek) numbers below follow the DPPDP form, not a verbatim XSD.

When this applies

• Legal persons file annually. Deadline is generally 3 months after the tax period end; 4 months if filed electronically (and a data box is mandatory for many entities) and 6 months with a tax advisor / statutory audit.
• The return must accompany the financial statements; advances (zálohy) paid during the period are offset against the final liability.

Structure (DPPDP → XML)

Header (VetaD)   tax period (zdaňovací období) from–to, return type (řádné/opravné/dodatečné), DIČ
Payer (VetaP)    entity identification (IČO, name, address), main activity (CZ-NACE)
Tax base build:
   ř.10          accounting profit/loss (výsledek hospodaření před zdaněním)
   ř.20–62       additions: non-deductible expenses, tax vs accounting depreciation diff, provisions
   ř.100–162     deductions: exempt income, dividends, prior-period adjustments
   ř.200         tax base before relief (základ daně)
   ř.230         deduct tax losses carried (odpočet daňové ztráty)
   ř.240–243     deduct R&D / training / donations
   ř.250         adjusted tax base
   ř.280         tax at current rate (daň)
   ř.300–360     tax credits (slevy na dani — e.g. disabled employees, investment incentives)
   ř.340         tax after relief
Settlement:      advances paid (zálohy) → balance to pay or refund

Data rules

• Start from accounting profit/loss (ř.10); apply additions (e.g. non-tax expenses, accounting-vs-tax depreciation difference, unpaid liabilities) and deductions (exempt income, participation-exemption dividends).
• Tax depreciation (daňové odpisy) follows the Income Tax Act categories, separate from accounting depreciation — report the difference.
• Tax-loss relief may be carried forward 5 years (and back 2 years up to a cap); apply before computing tax.
• Tax = adjusted base × current CIT rate (21%); then apply slevy na dani (credits) and offset advances.
• Round the tax base down to whole CZK thousands and the tax to whole CZK per the form's rounding rules.

Worked example (outline)

Header: DIČ=CZ12345678, period 2025-01-01..2025-12-31, type=řádné
ř.10 accounting profit 5,000,000
ř.40 + non-deductible expenses 300,000 ; ř.50 + depreciation diff 200,000
ř.110 − exempt dividends 500,000
ř.200 base 5,000,000 ; ř.230 − loss carried 1,000,000
ř.250 base 4,000,000 (rounded down to thousands)
ř.280 tax = 4,000,000 × 21% = 840,000 ; ř.340 after credits 800,000
less advances 600,000 → balance to pay 200,000 CZK

Emitted as a DPPDP XML and submitted via EPO / DIS+ (data box for mandatory filers).

Validation checklist

• Current DPPDP schema (dppdp_epo2.xsd) used; type (řádné/opravné/dodatečné) correct
• DIČ, IČO, tax period and CZ-NACE activity correct
• Additions/deductions complete; tax-vs-accounting depreciation difference reported
• Tax-loss relief within the 5-year carry-forward limit
• Tax = base × current CIT rate (21%); slevy na dani applied
• Base rounded down to CZK thousands; tax rounded to whole CZK
• Advances (zálohy) offset; filed electronically (data box) by the 3/4/6-month deadline
