Sole Proprietor Taxation – Not as Scary as It Sounds
Welcome to the wonderful world of entrepreneurship! You’ve set up a sole proprietorship, you have a brilliant business idea, and you’re buzzing with excitement. Then you hear the word “taxation,” and the mood drops faster than a lead balloon.
Relax. Sole proprietor taxation sounds more complicated than it is. It’s not quantum physics, even though letters from the tax office might sometimes look like it. Think of this guide as your personal trainer in the tax jungle – we’ll go through it step by step, without the unnecessary jargon.
The biggest difference between being an employee and a sole proprietor is this: as an employee, your employer handles tax withholding for you. As an entrepreneur, you are responsible for it yourself. You are now the captain, the first mate, and the ship’s cook. But don’t worry, this ship will stay afloat.
Calculating Business Income: How is Profit Actually Calculated?
At the heart of everything is your sole proprietorship’s profit. That’s the amount the taxman wants his slice of. Fortunately, the formula is simple, and anyone can learn it:
Business Revenue - Business Expenses = Taxable Business Income (i.e., Profit)
Revenue is all the money you bill your clients for your services or products (excluding the VAT portion). Expenses, on the other hand, are all the costs directly related to your business operations – from your laptop to your accountant’s fee.
If you have been an entrepreneur for a while and the previous year was unprofitable, you can deduct past losses from future years’ profits. Naturally, in your first year, there are no losses, so the calculation is even simpler.
This is the foundation of the whole thing. Once you know how to calculate your profit, you’re already halfway there.
Earned Income vs. Capital Income – The Entrepreneur’s Secret Tax Recipe
Now let’s dive a little deeper. Unlike a salary, which is taxed entirely as earned income, a sole proprietor’s taxable income is divided into two parts: capital income and earned income.
This division can save you a pretty penny, so it’s worth paying attention.
What on Earth Are Net Assets?
To understand this division, you need to know the term net assets. It’s simply your business assets minus your business liabilities.
- Assets include things like work computers, tools, money in the bank account, and accounts receivable.
- Liabilities include things like accounts payable and loans taken out for the business.
Example: If you have a work laptop worth €5,000 and €2,000 in your business bank account, but also a €1,000 debt to a supplier, your net assets are: (€5,000 + €2,000) - €1,000 = €6,000
Net assets are always calculated based on the situation at the end of the previous tax year. If you are a new entrepreneur, your net assets in the first year are zero.
The Capital Income Portion
The capital income portion is calculated as a percentage of the previous year’s net assets. By default, this percentage is 20%. The tax rate for capital income is fixed: 30% up to €30,000 and 34% on the amount exceeding that.
However, as an entrepreneur, you can request that the capital income portion be calculated as 10% or even 0% instead of 20%. This can be beneficial if your earned income is low and progressive taxation is more advantageous for you.
The Earned Income Portion
Whatever is left of the business profit after the capital income portion is deducted is taxed as earned income. The taxation of earned income is progressive, just like salary income. The more you earn, the higher your tax rate.
Your earned income tax rate is also affected by any other earned income you may have, such as from a salaried job or benefits.
Let’s Calculate an Example!
Imagine your sole proprietorship’s taxable profit is €30,000 and the previous year’s net assets were €10,000.
Capital Income Portion (20%):
- 0.20 * €10,000 = €2,000
- Tax on this portion: 0.30 * €2,000 = €600
Earned Income Portion:
- €30,000 (total profit) - €2,000 (capital income portion) = €28,000
- The tax on this portion is calculated progressively according to your personal tax rate.
Tip: If you are a new entrepreneur and have no net assets, your entire year’s profit is taxed as earned income. This is important to remember when estimating your first year’s taxes!
The Entrepreneur Deduction – A Small Gift from the Taxman
Here’s some good news! As a sole proprietor, you automatically get a 5% entrepreneur deduction. This is the tax authority’s way of giving you a pat on the back and saying, “Good job, keep it up!”
The deduction is calculated from the business profit after any previous losses have been subtracted. You don’t have to apply for it separately; the Tax Administration does it for you. It’s like a free lunch, but without feeling stuffed.
In our example, with a profit of €30,000, the entrepreneur deduction would be €1,500 (0.05 * €30,000). This means your taxable income is actually only €28,500, which reduces the amount of tax you have to pay. Not a bad deal!
Prepayment Tax: Pay Now, Don’t Cry Later
Prepayment tax is probably one of the most confusing aspects of entrepreneurship. But the principle is simple: it’s a way to pay your taxes in installments throughout the year, so you don’t end up with a huge, lump-sum tax bill at the end of the year.
Think of it as a tax payment plan or subscription. Instead of Netflix, you’re subscribing to society’s services.
How Does Prepayment Tax Work?
- Estimate Your Profit: When you start your sole proprietorship, you need to estimate your profit for the first fiscal period. Be realistic! An overly optimistic estimate will lead to overly large tax installments, and an overly pessimistic one can come back to bite you as a massive tax bill.
- The Tax Administration Calculates the Tax: Based on your estimate, the Tax Administration calculates the amount of your prepayment taxes and sends you the payment slips. There are usually 2, 3, 6, or 12 installments per year, depending on the tax amount.
- Apply for Changes if Necessary: Life is full of surprises. If you notice your profit is going to be much higher or lower than estimated, immediately apply for a change to your prepayment tax in the MyTax service (OmaVero). This is absolutely crucial! Don’t pay too much or too little; update your estimate to reflect reality.
For established entrepreneurs, the Tax Administration automatically sets the prepayment tax based on the previous year’s taxation. If you know the upcoming year will be different, remember to go in and change the estimate.
Changing your prepayment tax is quick and easy. It’s like updating your social media profile—but much more financially beneficial.
The Sole Proprietor’s Tax Return – The Most Important Paperwork of the Year
When the fiscal year is over, it’s time to file your sole proprietor’s tax return. This is the moment of truth where you tell the Tax Administration how the year really went. The tax return is usually due in the spring, and the exact date will be announced in MyTax.
On the tax return, you declare:
- Your actual income for the fiscal period.
- All business-related expenses and deductions.
- Business assets and liabilities (i.e., the information needed to calculate net assets).
This is the moment you’ll thank yourself for keeping your bookkeeping and receipts in order all year. Well-managed bookkeeping makes filling out the tax return almost enjoyable. Well, maybe not enjoyable, but at least bearable.
Once the tax return is processed, the Tax Administration will calculate your final tax.
- If the prepayment taxes you paid were more than the final tax, you’ll get a tax refund.
- If you paid too little, you’ll have to pay residual tax (back taxes).
VAT, or Value-Added Tax – The Entrepreneur’s Eternal Partner
Although Value-Added Tax (VAT) is not an income tax, it is an essential part of daily life for most sole proprietors.
When Do I Need to Register for VAT?
You must join the VAT register if your turnover in a 12-month fiscal period exceeds €15,000. You can also register voluntarily even if your turnover doesn’t exceed the threshold. This can be worthwhile if you have many purchases that include VAT.
How Does VAT Work?
- You Add VAT to Your Sales Prices: When you sell a product or service, you add VAT to the price (usually 25.5%).
- You Collect the Tax from the Customer: The customer pays you a price that includes VAT. This VAT portion is not your money; you are just its temporary custodian.
- You Deduct the VAT from Your Own Purchases: When you make purchases for your business, you can deduct the VAT they contain.
- You Remit the Difference to the Tax Administration: You pay the Tax Administration the difference between the VAT you collected from your sales and the VAT you deducted from your purchases.
VAT is usually declared and paid monthly, quarterly, or annually, depending on the size of your turnover.
VAT Relief for Small Businesses – A Carrot for the Small Entrepreneur
If your turnover is less than €30,000 per year, you are entitled to VAT relief (known as alarajahuojennus). This means you can get back some or all of the VAT you have remitted. It’s a significant financial benefit that you should definitely take advantage of!
What Expenses Can I Deduct? – Top Tips for Tax Deductions
Tax deductions are an entrepreneur’s best friend. They reduce your taxable income and, therefore, the amount of tax you pay. The rule of thumb is:
You can deduct all expenses incurred in acquiring or maintaining your business income.
Here is a list of the most common deductible expenses:
Tools and Supplies
- Computer, phone, monitor, and other devices.
- Software licenses (e.g., Microsoft Office, Adobe Creative Cloud).
- Office supplies like paper, pens, and binders.
- Professional literature and industry-related magazines.
Marketing and Sales
- Advertising campaigns (Google, Facebook, etc.).
- Printing costs for business cards and brochures.
- Website creation and maintenance costs.
Workspace
- Rented Workspace: Rent and other costs are fully deductible.
- Working from Home: You can either deduct costs using a formula-based home office deduction (amounts vary annually, e.g., €940, €470, or €235 depending on the extent of use) or based on actual expenses if you can itemize them.
Travel Expenses
- Use of a Personal Car: You can deduct mileage allowances for business trips by keeping a travel log.
- Public Transport Tickets: Tickets used for business travel.
- Per Diem Allowances: You can pay yourself a tax-free daily allowance for business trips lasting over 6 or 10 hours.
Other Expenses
- YEL Insurance Premiums: Your entrepreneur’s pension insurance is fully deductible.
- Other Insurance: For example, liability insurance or accident insurance.
- Fees for an accountant and other experts.
- Entertainment Expenses: For example, business lunches with clients. Note! Only 50% of these are deductible.
Remember to save all receipts! Without a receipt, there is no deduction. Fortunately, there are now handy apps that let you scan and save receipts instantly.
Summary: Sole Proprietor Taxation is Manageable
Phew, we made it! As you can see, sole proprietor taxation is not a secret science, but a set of logical rules. Once you learn the basic principles, you’ll do just fine.
Here’s a quick recap of the most important points:
- Profit is Key: Your taxes are based on your business’s profit (revenue - expenses).
- Know Your Income Types: Profit is divided into capital and earned income, which affects the amount of tax.

Don’t be afraid to ask for help. An accountant or tax advisor can be worth their weight in gold, especially at the beginning. You focus on what you do best – running your business – and let a professional help with the number-crunching when needed.
Good luck on your entrepreneurial journey!
