Frequently Asked Questions

When is the VAT return due in this country?
VAT return deadlines vary by filing frequency. Monthly filers typically need to submit by the 15th-25th of the following month. Quarterly filers submit by the end of the month following the quarter. Always check with the local tax authority for specific deadlines.
When is the corporate income tax return due?
Corporate income tax returns are generally due within 5-9 months after the end of the financial year. Most countries follow the calendar year, with returns due between March and September of the following year. Extensions are often available.
What happens if I miss a tax deadline?
Late filing penalties vary by country and tax type. Common penalties include fixed fines, percentage-based penalties on tax due, and daily interest accrual. Penalties often increase the longer the delay.
Are VAT rules harmonised across the EU?
Yes, the EU VAT Directive provides a common framework. However, each member state has some flexibility in setting rates, thresholds, and specific deadlines. Cross-border transactions within the EU follow special rules including reverse charge mechanisms.
Do I need to register for VAT in multiple EU countries?
If you sell goods or services to customers in other EU countries, you may need to register for VAT in each country or use the One-Stop Shop (OSS) scheme to declare VAT centrally. The threshold for distance selling varies by country.
