Elafgift Reduction 2026: How to Claim Every Eligible Ore of Energy Tax Refund

Elafgift is the energy tax charged on electricity supplied to Danish addresses. In 2026 the standard rate is DKK 1.042 per kWh for households, but commercial consumers can reclaim a significant portion via their moms return. The key distinction: electricity used for procesformal (production processes, equipment, servers, tools) is generally reclaimable, while electricity used for rumvarme (space heating, hot water in non-production rooms) is not reclaimable unless specific documentation is provided. The 2026 update simplified the rumvarme carve-out but tightened the documentation requirements, making accurate invoice classification more important than ever.

The refund mechanism works through rubrik on your momsangivelse. You declare the electricity consumption, calculate the reclaimable portion at the 2026 rate, and subtract that amount from the VAT you owe SKAT. For a small workshop spending DKK 40,000/year on electricity, the reclaim typically runs DKK 3,000-5,000. For a bakery or production facility it can reach DKK 15,000-30,000.

Effective 1 January 2026, the Danish government adjusted three key elements of the elafgift regime. First, the base rate rose from DKK 1.016/kWh to DKK 1.042/kWh — a 2.5% increase. Second, the minimum consumption threshold for full refund eligibility was lowered from 4,000 kWh/year to 2,500 kWh/year, bringing more micro-businesses into the reclaim system. Third, the documentation rules for mixed-use premises (where both proces and rumvarme consumption occur) were replaced with a simplified 70/30 rule: if your premises are primarily production (>70% of floor area), you can default to full reclaim without a heat meter installation.

The net effect for most Danish SMBs is a slightly higher refund in absolute kroner and a much lower compliance burden — provided your accounting system correctly identifies energy invoices and runs the new rates. Systems that use the 2025 rates will undercalculate by roughly 2.5% and miss the expanded threshold eligibility.

Qualification for elafgift refunds depends on three criteria: VAT registration (you must be a registered Danish VAT subject), commercial use (the electricity must be consumed for business activities), and invoice documentation (you must have a proper faktura showing the elafgift line item separately). Most registered Danish businesses qualify for at least a partial refund. Exclusions include pure holding companies without operating activity, educational institutions, and certain public-sector entities.

To verify your own eligibility, start with a single quarter of electricity invoices. Look for the line item labelled elafgift (sometimes el-afgift or elektricitetsafgift). The total kWh consumed should be visible on the invoice — usually in a usage summary section. If your invoice does not show kWh and afgift separately, contact your electricity supplier and request a specified faktura — Danish law requires them to provide one on request. Without a specified invoice you cannot claim the refund.

Here's what the manual calculation looks like for a single quarter: open each electricity invoice, find the kWh consumed, multiply by the 2026 rate of DKK 1.042, subtract any non-reclaimable rumvarme portion, adjust for period boundaries if the invoice straddles a quarter, check against the 2,500 kWh threshold, and then manually enter the total into the correct rubrik on your momsangivelse. Do this for every energy invoice (electricity, water, gas, oil, coal, CO2, NOx) across every site your business operates. For a single-site SMB the process takes 30-60 minutes per quarter. For multi-site operations it can take half a day.

The error rate is high. Common mistakes include using the previous year's rate, forgetting to exclude rumvarme, missing invoices that arrived after the period cutoff, and applying the 70/30 rule incorrectly. Each error is either a refund you didn't claim (direct cost) or a refund you overclaimed (audit risk). SKAT's audit spotlights have found systematic over-claims in construction, hospitality, and logistics — sectors where rumvarme and proces consumption are routinely mixed.

Moms Autopilot's energy tax module automates every step of this process. When your e-conomic ledger receives an electricity invoice, the system detects it via supplier pattern matching (Orsted, Norlys, NRGi, EnergiFyn, and others are all recognised). It then extracts the kWh consumed, applies the 2026 rate, checks the 70/30 rule against your stored building metadata, calculates the reclaimable amount, and automatically adds it to the correct rubrik on your running momsopgorelse. You see a per-invoice breakdown on the dashboard and can adjust any classification with a single click.

At period close, the full elafgift refund is already calculated and ready to file. The audit trail stores every invoice, rate applied, and rule outcome, so in the event of a SKAT audit you can prove compliance without reopening shoeboxes. Most SMBs recover their annual Moms Autopilot subscription cost from elafgift alone in the first quarter.
