Swedish taxes are complicated. Between different income sources, tax tables, and deductions you might be missing — it's hard to know if you'll owe money or get a refund. Moonii gives you clarity, all year round.

The gap
Actual rate

your real tax rate
That 20% gap on 100,000 kr side income = 20,000 kr surprise in April
Most people don't know their true tax situation until declaration time. Here's why — and how Moonii helps.
Let's say you earn:
Main job
450,000 kr
Side gig
100,000 kr
Total income
550,000 kr
What actually happens:
Sweden taxes higher income at higher rates. Your side income sits on TOP of your main income.
Each employer only knows about their payment to you. They can't calculate your total tax burden.
The 30% withholding on secondary income is a simplified estimate — often too low.
Moonii isn't just about avoiding tax bills. It's about understanding your complete tax picture.
Catch under-withholding from multiple jobs or wrong tax tables before it becomes a problem.
Find deductions you're missing — work travel, union fees, ROT/RUT, and more.
Make sure your employer is using the right tax table for your situation.
Don't wait until declaration time. Know where you stand every month.
No signup. No email. Just clarity.
