Keeping your bookkeeping in order is essential for running a successful business in Denmark. Accurate financial records help ensure compliance with tax laws, make it easier to monitor cash flow, and prevent costly errors. Whether you are a sole proprietor or manage a limited company, understanding bookkeeping best practices can save time and reduce stress. This guide outlines key steps and tips for entrepreneurs to manage their bookkeeping efficiently and stay compliant with Danish regulations.
Understanding Your Bookkeeping Responsibilities
Bookkeeping in Denmark involves systematically recording and managing all financial transactions of a business. Every company must:
- Maintain accurate records of income and expenses.
- Keep documentation, such as invoices and receipts, for at least five years.
- File VAT returns if registered for Moms (Danish VAT).
- Submit annual financial reports (for ApS and A/S companies).
- Separate personal and business finances to ensure financial transparency.
By keeping your books in order, you can easily track profitability and meet tax obligations without complications.
Choosing the Right Bookkeeping Method
Entrepreneurs in Denmark can choose between two bookkeeping methods:
- Single-entry bookkeeping – Used by small businesses and sole proprietorships, where income and expenses are recorded individually.
- Double-entry bookkeeping – Required for limited companies (ApS and A/S), ensuring that every financial transaction is recorded in two accounts (debit and credit).
Choosing the right method depends on your business size and reporting obligations. Many entrepreneurs start with single-entry bookkeeping and upgrade to double-entry as their business grows.
Using Accounting Software to Simplify Bookkeeping
Managing bookkeeping manually can be time-consuming, which is why many Danish entrepreneurs use accounting software. Popular options include:
- Dinero – Ideal for freelancers and small businesses, offering simple invoicing and tax calculation tools.
- Economic – Suitable for medium and large businesses, providing advanced bookkeeping features.
- Billy – User-friendly software designed for startups and independent entrepreneurs.
Using software helps automate financial tracking, generate reports, and reduce human errors.
Registering for VAT (Moms) and Keeping Track of Tax Obligations
If your business generates more than 50,000 DKK in annual revenue, you must register for VAT (Moms). The Danish VAT rate is 25% for most goods and services.

To stay compliant:
- Register for VAT through the Virk.dk portal.
- Charge VAT on invoices and keep detailed records.
- Submit VAT returns monthly, quarterly, or annually, depending on your revenue.
- Claim deductions for VAT paid on eligible business expenses.
Tracking VAT properly ensures that you do not overpay or underpay your tax obligations.
Keeping Track of Business Expenses
One of the most important bookkeeping tasks is tracking expenses. Proper expense management helps reduce taxable income and ensures financial accuracy.
To keep records organized:
- Categorize expenses (e.g., office rent, supplies, travel costs, advertising).
- Keep digital or paper copies of receipts and invoices.
- Use a company bank account to separate business and personal transactions.
- Reconcile bank statements monthly to catch discrepancies early.
Maintaining clear records of expenses will make tax deductions easier and prevent accounting mistakes.
Issuing and Managing Invoices
Invoices serve as legal proof of transactions and are crucial for bookkeeping. In Denmark, invoices must include:
- Your company’s CVR number (business registration number).
- Invoice date and unique invoice number.
- Description of goods or services provided.
- VAT rate (if applicable) and total amount.
To streamline invoicing, consider using automated accounting software that tracks payments and sends reminders for overdue invoices.
Payroll and Employee Bookkeeping
If your business has employees, payroll management is a critical part of bookkeeping. You must:
- Register as an employer with SKAT (Danish Tax Authority).
- Withhold income tax and social security contributions from salaries.
- Report wages through the eIndkomst system.
- Pay holiday allowances and other employee benefits according to Danish labor laws.
Using payroll software or outsourcing payroll to a professional accountant can help prevent errors in tax calculations.
Separating Business and Personal Finances
Mixing personal and business finances can lead to bookkeeping confusion and tax complications. To avoid this:
- Open a business bank account for company transactions.
- Use a dedicated credit card for business-related purchases.
- Pay yourself a salary instead of withdrawing funds randomly from the business.
Clear separation of finances helps maintain accurate records and simplifies financial reporting.
Tracking Cash Flow and Financial Health
Understanding your business’s cash flow is essential for making informed financial decisions. To stay on top of cash flow:
- Monitor monthly revenue and expenses.
- Set up cash flow projections to anticipate upcoming costs.
- Avoid late payments by following up on outstanding invoices.
Good cash flow management prevents liquidity issues and ensures long-term business stability.
Filing Annual Reports and Tax Returns
Danish businesses must comply with annual reporting requirements. Key deadlines include:

- VAT returns – Submitted monthly, quarterly, or annually, depending on company revenue.
- Corporate tax returns (for ApS and A/S) – Filed by July 1st of the following year.
- Personal tax returns (for sole proprietors) – Filed by May 1st each year.
Using an accountant can help ensure that all reports are filed on time and in accordance with tax laws.
Common Bookkeeping Mistakes and How to Avoid Them
Entrepreneurs often make errors in bookkeeping that can lead to financial issues. Common mistakes include:
- Forgetting to track small expenses – Every expense matters for tax deductions.
- Failing to register for VAT on time – Late registration can result in fines.
- Not backing up financial records – Digital records should be stored securely.
- Missing tax deadlines – Late tax filings can lead to penalties.
Using professional bookkeeping services or automated accounting tools can help prevent these errors.
Outsourcing Bookkeeping vs. Doing It Yourself
Some entrepreneurs choose to manage bookkeeping themselves, while others prefer outsourcing. Consider the following:
- DIY Bookkeeping – Suitable for small businesses with minimal transactions. Requires time and knowledge of Danish tax laws.
- Outsourcing – Hiring an accountant or bookkeeping service saves time and ensures accuracy. Ideal for growing businesses with complex finances.
Weighing the cost and benefits of each option can help determine the best approach for your business.
Effective bookkeeping is crucial for Denmark’s financial stability and legal compliance. By implementing best practices such as using accounting software, tracking expenses, managing invoices properly, and staying on top of tax obligations, entrepreneurs can simplify their bookkeeping and focus on business growth. Whether handling finances independently or outsourcing to professionals, maintaining organized financial records will ensure long-term success.
