K4 Filing with Skatteguru
Last updated: June 13, 2026
Use this guide when you already have data in Skatteguru and want to review your K4 output, resolve incomplete data, and file with confidence.
Skatteguru prepares K4-ready data from your uploaded broker exports and documents, but you still need to review the result before filing. This guide focuses on the product workflow: missing acquisition data, filing instructions, and SRU export.
Need K4 basics first?
What Skatteguru gives you
- Grouped K4 rows and section totals based on your source data.
- Filing instructions that show where section totals belong in the Swedish declaration flow.
- An SRU export path when you want Skatteverket import to carry over the prepared values.
Recommended filing path
What 'Incomplete Data' usually means
Missing buy history
Corporate actions
Cross-broker history gaps
How to resolve incomplete data in practice
- Upload missing broker exports or confirmations from every place where the asset was bought, transferred, or sold.
- Use the generic CSV format when you need to add missing historical trades manually.
- Review special-rule scenarios such as same-day sales, currency conversion, short sales, or foreign-currency holdings if they affect your cost basis.
Upload native exports first
How to file once the review looks right
When your K4 review is complete, use the filing instructions in Skatteguru and prefer SRU import when available.
Two common filing paths
- SRU import in Inkomstdeklaration 1: best when you want the prepared section totals moved into the correct declaration fields automatically.
- Manual filing: use Skatteguru’s totals and copy them into the declaration fields yourself.
If you are using SRU files, follow the detailed step-by-step guide here:
When Skatteguru may still need manual judgment
Some situations remain judgment-heavy even with good source data: transferred holdings, incomplete historical records, and corporate actions with non-trivial cost-basis effects.
In those cases, use the K4 review as a structured checkpoint, not a substitute for verifying the underlying tax treatment.
