Sweden ISK Schablonskatt Calculator 2027
Estimate your 2027 ISK schablonskatt under the SEK 300,000 tax-free threshold rule. Compare with ordinary brokerage tax to confirm ISK is still best for your portfolio size.

Sweden's Investeringssparkonto (ISK) replaces capital gains tax with a flat presumed-yield tax (schablonskatt). The rate equals statslåneräntan (Swedish government bond yield, November of prior year) + 1 percentage point, minimum 1.25%. Multiplied by your capital base (average quarterly balance + 50% of new deposits), the resulting schablonintäkt is taxed at 30%. The 2026 reform introduced a SEK 300,000 tax-free threshold starting in tax year 2027.
How Schablonskatt Is Computed
Step 1: capital base = (Q1 + Q2 + Q3 + Q4 average balances + value of deposits during year × 50%) / 4. Step 2: rate = statslåneräntan (Nov of prior year) + 1.0 pp, minimum 1.25%. Step 3: schablonintäkt = capital base × rate. Step 4: tax = schablonintäkt × 30% income tax rate. No capital gains are ever realized for tax — buying and selling inside ISK is free. Dividends from foreign stocks are still subject to withholding tax in the source country, but you can claim treaty relief via Skatteverket.
2026 SEK 300,000 Threshold Reform
From tax year 2027 (the year the reform takes full effect for the first time), the first SEK 300,000 of ISK capital base is exempt from schablonskatt. This makes ISK the strictly better choice for any portfolio under SEK 300k — you pay zero schablonskatt. Above that threshold, only the excess balance is taxed. For a SEK 800k balance at 3.5% schablon rate, that's a saving of SEK 300,000 × 3.5% × 30% = SEK 3,150 per year. Married couples each get their own SEK 300k threshold (so SEK 600k combined). Crucially, the reform applies to ISK and to kapitalförsäkring (KF) the same way.
