If you\u2019ve just started as a natural self-employed in Belgium, it might happen that your business makes a loss in the first year. This is because even as a self-employed, you have start-up costs and investments to make, and it can sometimes take a while before you start making a profit. <\/b><\/p>\n

\n

Nevertheless, a healthy business should at least break even over time. Otherwise, the tax authorities will start to question why you keep going despite not making money. Although making a loss isn\u2019t necessarily a problem, it may increase the chances of a tax audit. But don\u2019t let this cause panic \u2013 everyone can have a down year from time to time. <\/b>As long as your accounts are in order and there\u2019s a logical explanation for the situation, your loss need not have any other major consequences. This article explains how to deal with tax losses as a private individual self-employed.<\/p>\n

\n

\n

1. What is a tax loss?<\/h1>\n

Profit and loss are accounting concepts. It\u2019s therefore not enough to simply offset your income and expenses. Because in addition to the ordinary expenses your business incurs, you\u2019ve probably also made some investments. These investments are amortised over several years, meaning that only a part of the investment appears in your accounts each year, depending on the number of amortisations. <\/p>\n

\n

You make a loss when you have more expenses and investments than income in a financial year. Losses can be due to various factors.<\/b> For example, when your start-up costs (expensive equipment, training, etc.) are higher than your income in the first year. Or when you\u2019ve been unable to work for a period of time (e.g. due to illness), but expenses like office rental or software subscriptions still need to be paid.<\/p>\n

\n

The result is a negative balance sheet and thus, a tax loss. For example, if you incurred expenses of \u20ac18,000 while \u2018only\u2019 making \u20ac16,000 in income, you have a loss of \u20ac2,000.<\/p>\n

\n

\n

2. How do I declare losses in my income tax return as a full-time self-employed?<\/h1>\n

You declare the income from your activity as a full-time self-employed through your personal income tax return<\/a><\/b>, along with any other income you may have. This is also where you declare a loss. The amount should be mentioned in box VIII, code 1349 in Tax-on-web. <\/b><\/p>\n

\n

What happens with this loss depends on your personal situation and any other income you may have.<\/p>\n

\n

\n

Situation 1: you have other sources of income<\/h2>\n

If you have other income (e.g. rental income) besides your main self-employed occupation, your loss will be \u2018absorbed\u2019 by your other income<\/b>, so to speak. The tax authorities will offset your loss against your other income, which means you\u2019ll pay less tax on the other income. <\/b><\/p>\n

\n

The same happens when you\u2019re married or legally cohabiting.<\/b> In this case, your taxes are calculated together with those of your partner, so the loss from your self-employment will be offset against your partner\u2019s income. He or she will then pay less tax.<\/p>\n

\n

Situation 2: you\u2019re full-time self-employed<\/h2>\n

Are you self-employed in a main occupation and your business is your only source of income? Then the loss is usually carried forward to the following year and deducted from any profit there<\/b>. As a result, you\u2019ll pay less tax the following year.<\/p>\n

\n

\n\n\n\n
\n

\u26a0\ufe0f In both situations, the loss is automatically registered by the tax authorities. But it\u2019s best to double-check this. If it\u2019s not done automatically, you have to declare your loss yourself in box VIII, code 1349 of your personal income tax return.<\/b><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n

\n

3. How do I declare losses in my income tax return as a complementary self-employed?<\/h1>\n

\n

You declare the income from your activity as a complementary self-employed through your personal income tax return<\/a><\/b>, along with any other income you may have. This is also where you declare a loss. The amount should be mentioned in box VIII, code 1349 in Tax-on-web. <\/b><\/p>\n

\n

When you\u2019re self-employed in a secondary occupation, it\u2019s also possible to make a loss on your self-employed activity. For example, as a part-time nail stylist just starting out, you could have bought \u20ac1,500 worth of equipment and only had an income of \u20ac600 from your secondary occupation.<\/p>\n

\n

As a self-employed person in a secondary occupation, the distinction between your private assets and those of your business can be hard to ascertain. This is especially the case if you work from home, as many of your expenses are used for both your private and your self-employed activities. <\/p>\n

\n

Therefore, think carefully about what percentage you deduct for your mixed expenses, such as costs related to your workplace, your car, your computer and your mobile phone. In the event of a tax audit, you should be able to explain how you calculated those percentages. <\/p>\n

\n

The same happens when you\u2019re married or legally cohabiting.<\/b> In this case, your taxes are calculated together with those of your partner, so the loss from your self-employment will be offset against your partner\u2019s income. He or she will then pay less tax.<\/p>\n

\n\n\n\n
\n

As a complementary self-employed person, your losses will be “absorbed” to some extent by your employee income.<\/b> In this case, the tax authorities will offset your losses against your employee income, enabling you to pay less tax on your employee income.<\/b><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n

\n

4. Do you get taxed when you make?<\/h1>\n

No, if you don\u2019t make a profit, you don\u2019t pay taxes. It\u2019s as simple as that. <\/b>Well, provided your accounts are in order and there\u2019s<\/b> a logical explanation for the loss<\/b>.<\/p>\n

\n

Many self-employed people try to limit their profits by amassing professional expenses, thereby reducing the tax burden. However, this starts to become problematic if you also deduct expenses that have little or nothing to do with your business<\/b>. That Saturday night dinner with friends or your new jeans have little professional value. So be careful with claiming expenses that have no clear link to your professional activity. <\/p>\n

\n

\n\n\n\n
\n

\ud83d\udca1 Accountable tip:<\/b> Not sure exactly which professional expenses you can deduct, and how much of them? Then have a look at our searchable database of professional expenses.<\/a><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

5. Is a tax audit more likely if you make a loss?<\/h1>\n

\n

The tax authorities may indeed be a little quicker to visit businesses that regularly make losses. However, if everything\u2019s in order, this need not be a problem.<\/b><\/p>\n

\n

It\u2019s worth remembering that a tax audit is always possible, even without a specific reason<\/b>. The tax authorities can go back up to three years in your accounts, which is a good reason to keep everything neat and tidy anyway. <\/p>\n

\n

As we already mentioned, it\u2019s not unusual to make a loss in the first few years when you start a business<\/b>. Between start-up expenses and a customer base that\u2019s still small, it can be hard to break even. What\u2019s more, even seasoned entrepreneurs can have down years from time to time, whether due to a wider economic crisis or for more personal reasons.<\/p>\n

\n

That said, it\u2019s always good to understand where your losses are coming from. This is important when the tax authorities ask you questions, but also, of course, for yourself.<\/p>\n

\n

\n\n\n\n
\n

Recording losses shouldn’t be a problem, especially if they’re exceptional. However, if you record losses, especially if they occur frequently, you’re likely to attract the attention of the tax authorities.<\/b> That’s why it’s a good idea to deduct only expenses that are really linked to your business.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
