Income tax on self-employed profit, plus how much BTW (VAT) collected should be set aside for the quarterly return.

Open a step for the sum with your figures, what the step does, and what the Dutch terms mean.
What this step does: Your profit is what the business earned after its costs. This is the starting point for every tax a freelancer pays.
What this step does: Entrepreneurs who are in business for themselves get deductions that ordinary employees don't. They are taken off the profit before income tax is worked out, so they lower the tax, not your revenue.
What this step does: Box 1 is the tax on income from work and your home. The income is cut into brackets and each slice is taxed at its own rate, so a raise never lowers your net pay through the brackets alone. Then the tax credits (heffingskortingen) are taken off the tax itself.
The labour tax credit is based on the profit before the deductions.
What this step does: Keep the BTW on your invoices apart from day one: you pay it over every quarter, minus the BTW on your own business costs.
BTW is not your money: you charge it to clients and pay it to the tax office every quarter.
What this step does: What you actually keep: the profit minus income tax and the income-related health-care contribution (Zvw), which freelancers pay themselves.
What if I don't meet the 1,225-hour urencriterium?
You still pay income tax and Zvw on your profit as normal, but you lose access to zelfstandigenaftrek and startersaftrek. The MKB-winstvrijstelling still applies regardless.
Do I need to register for BTW separately?
No, registering as a business with the KVK automatically registers you for BTW; the Belastingdienst sends your BTW-nummer shortly after (unless you opt into KOR).
Is KOR always worth it under the threshold?
Not necessarily. If you buy a lot of BTW-taxed equipment or services for your business, reclaiming that input VAT (only possible outside KOR) can outweigh the simplicity of not charging BTW at all.
Is this the same as corporate tax?
No, this models a sole trader (eenmanszaak/ZZP) taxed through personal income tax (Box 1), not a BV, which pays separate corporate income tax (vennootschapsbelasting).

Ignores any BTW paid on business purchases when KOR isn't used (the set-aside figure is gross output VAT, not the net amount owed after input-VAT deduction). For a precise number, consult your bookkeeper or the Belastingdienst ondernemersportaal.
