Noisy contribution is the conversion of a sole proprietorship or general partnership into a private limited company (BV) with a tax settlement at the time of contribution. You pay income tax on the cessation profit (hidden reserves, goodwill), but the BV starts with a “step-up” — higher book values ​​— resulting in lower taxes in the future. Sometimes more favorable than a silent conversion, especially in the case of limited hidden reserves, a low cessation profit, or income tax losses that can still be utilized. The considerations are outlined below.

The short answer

  • What: conversion with immediate settlement of hidden reserves and goodwill.
  • Advantage: increase in book values ​​for BV — higher future depreciation.
  • When smart: small hidden reserves, income tax losses to offset, or a need for flexibility (no three-year continuation obligation).
  • Disadvantage: immediate income tax assessment on cessation profit.

The difference compared to silent

Two routes, opposing tax logic:

  • Silent contribution (Art. 3.65 Income Tax Act): no direct income tax, BV acquires book values, three-year continuation obligation. See silent contribution.
  • Ruisend: direct income tax settlement, BV starts with market values, no obligation to continue.

Which route fits depends on your untapped reserves, your IB position, and your horizon.

When is charging more economical?

Four situations:

  • Few hidden reserves. With limited goodwill or hidden reserves, the income tax assessment is low — while the step-up does create future depreciation headroom.
  • Income tax losses to offset. Do you have losses from previous years? With a contribution without tax implications, you can offset these against the cessation profit — often tax-favorable.
  • Utilizing the strike deduction. The strike deduction (max €3,630 in 2024) and strike annuity are only available in the case of a "noisy" strike.
  • Flexibility desired. No three-year continuation obligation — you may sell the BV shares earlier or cease the business.

The calculation

Example to make the assessment concrete:

  • Sole proprietorship with book value of assets € 50,000.
  • Actual (market) value € 60,000 — so hidden reserves € 10,000.
  • Goodwill € 15,000.
  • Total strike profit €25,000.

Noisy route: Income tax on € 25,000 minus cessation deduction (€ 3,630) = tax on € 21,370. At an average income tax rate of ~45% = ~€ 9,600 now. The BV starts with assets at € 60,000 + goodwill of € 15,000 = € 75,000. Future depreciation of that € 25,000 reduces corporate income tax profit (~25.8% corporate income tax) = ~€ 6,500 tax saving in later years.

Seamless route: no income tax now, but Box 2 (31%) on all profit upon sale of BV shares later. No step-up.

The net comparison depends on your rate, your time horizon, and your expectations. An accountant can calculate this for your situation — often in just a few hours.

Step-by-step plan

  1. Calculation by accountant or tax specialist: noise-generating versus noise-free.
  2. Establishing a BV at the notary.
  3. Deed of contribution with assets and liabilities at market value.
  4. Income tax return with cessation profit for the year of contribution.
  5. any cessation annuity within 12 months to spread the tax burden.

For the retroactive effect rules (3 months for taxable, 9 for tax-free): see Incorporating a BV with retroactive effect.

Honest recommendation

Noisy versus silent is not a one-size-fits-all approach. With growth and substantial goodwill, silent is often the smartest route; with small hidden reserves or income tax losses, noisy wins. Have an accountant perform the calculations — the difference between the routes can save thousands of euros in taxes.

For the opposite: silent contribution. For cessation profit detail: cessation profit upon conversion.

Frequently Asked Questions

What is noisy input?

Conversion of a sole proprietorship or general partnership into a private limited company (BV) with immediate income tax settlement on the cessation profit (hidden reserves and goodwill). The BV starts with assets at market value — a “step-up” that can result in lower taxes in later years.

When do you choose noisy over silent?

For limited hidden reserves, for income tax losses to offset, if you want to utilize the cessation deduction, or if you desire flexibility without a three-year continuation obligation. An accountant is best able to calculate which route suits your situation.

What is a step-up?

With a contribution subject to a taxable transaction, the BV starts with assets and goodwill at market value, not book value. A higher book value means higher future depreciation, and therefore lower corporate income tax profit and lower tax in later years. The difference often pays for itself.

How much income tax do you pay on strike profit?

Cessation gains fall under Box 1 with a progressive income tax rate. Cessation deduction (max €3,630 in 2024) and cessation annuity can reduce the assessment. Effective rate often 40–50%. Discuss the exact calculation with an accountant.

What is strike deduction?

A deduction from cessation profit (max €3,630 in 2024 for a one-off cessation). For entrepreneurs ceasing their business; only applicable to taxable contributions — not to tax-free contributions.

Until when can I opt for retroactive noise?

With a "noisy contribution," retroactive effect is limited to a maximum of 3 months — thus no later than the end of March to go back to January 1st. A "silent contribution" allows for a more generous period of 9 months.

What is a strike annuity?

A tax facility that allows you to deposit the cessation profit into an annuity, which reduces the immediate income tax assessment. Intended to spread tax over later years. Ask an accountant or tax specialist for the correct application — it often pays off for higher cessation profits.
