Bitcoin Social Security AHV Switzerland 2026

Income tax gets the attention. AHV sends the second bill.

I work in the crypto self-custody space, and the AHV question is the one most Swiss earners forget to ask. AHV, IV and EO contributions run on a parallel track to income tax, and the rules shift depending on whether you draw a salary, invoice as self-employed, or run a mining or staking setup.

This post walks four scenarios with the 2026 figures, cited to the law and the official Merkblätter. The BSV sheet of 6 November 2025 confirms that no amount changed against 1 January 2025.

TL;DR

Your AHV exposure depends on which of four boxes you sit in.

Salary paid in Bitcoin. AHV-pflichtig at the CHF value at the time of payment per AHVG Art. 5. The employer deducts the 5.3% employee share, adds its own 5.3%, and remits both to the Ausgleichskasse it is affiliated with. The Bitcoin denomination changes nothing.

Commercial Bitcoin mining. Mining run as self-employment produces AHV-pflichtig income. AHV/IV/EO applies on net profit: CHF 530 minimum below CHF 10,100, a sliding scale from 5.371% to 9.321% up to CHF 60,500, and a flat 10.0% on the whole net income from CHF 60,500, with no cap, per AHV Merkblatt 2.02. Whether the mining counts as self-employment is decided per case by the Ausgleichskasse.

Staking rewards. The ESTV working paper of 14 December 2021 treats pool-staking rewards of a private investor as income from movable assets, not earned income, so no AHV attaches. A solo validator is checked for self-employment. No BSV or Ausgleichskasse publication addresses staking specifically.

Self-employed Bitcoin income. You convert to CHF at receipt and pay on the same structure as the miner: CHF 530 minimum, sliding scale to CHF 60,500, then 10.0% on everything, uncapped.

AHV IV EO Base Rates 2026

The Swiss payroll system bundles three insurance pillars into one deduction. The 2026 rates per AHV Merkblatt 2.01, AHVG Art. 5 and Art. 13, IVG Art. 3 and EOG Art. 27:

The employer deducts the 5.3% employee share from each salary payment under AHVG Art. 14 and adds its own 5.3% (AHVG Art. 13 for the AHV part), remitting 10.6% to the Ausgleichskasse. ALV, the unemployment insurance, comes on top: 2.2% up to CHF 148,200 of annual salary, split 1.1% each, per Merkblatt 2.08. The Ausgleichskasse also charges the employer an administration-cost contribution.

Many employers and self-employed persons are attached to a Verbandsausgleichskasse rather than the cantonal one (AHVG Art. 64). Everything in this post that says "your Ausgleichskasse" means the one you or your employer is affiliated with.

Self-employed persons sit on a different structure. There is no employer share. The self-employed rate is 10.0% (AHV 8.1%, IV 1.4%, EO 0.5%) from CHF 60,500 net income; below that a sliding scale applies under AHVG Art. 8, AHVV Art. 21 and AHV Merkblatt 2.02.

Salary Paid in Bitcoin

When an employer pays salary wholly or partly in Bitcoin, the Bitcoin component is Naturallohn. AHVG Art. 5 Abs. 2 defines the contribution basis as the massgebender Lohn, which covers every form of remuneration for employment, Naturalleistungen included. AHVV Art. 7 lit. f lists them. Denominating in Bitcoin does not remove the amount from that basis.

The employer converts the Bitcoin amount to CHF at the market price at the moment of transfer. The ESTV working paper on cryptocurrencies of 14 December 2021 (ch. 2.2) sets the value at the time of inflow, converted to CHF, and the Wegleitung über den massgebenden Lohn follows the direct federal tax valuation for Naturaleinkommen. The ESTV Kursliste, the ICTax tool, publishes only a 31 December value per coin and cannot serve a payroll date. Document the CHF price on the day of transfer from the platform actually used and keep the printout with the payroll records. That CHF figure is the gross salary for payroll.

Operationally. The employer deducts 5.3% as the employee AHV/IV/EO share, adds a matching 5.3% employer share, and remits both quarterly (annual payroll up to CHF 200,000) or monthly, within 10 days after the period end (AHVV Art. 34). The Lohnausweis shows the CHF value at the time of payment (ESTV working paper 2021).

Example. A product owner earns CHF 100,000 per year, paid entirely in Bitcoin. Each month the employer transfers the BTC equivalent of CHF 8,333 at the prevailing price, withholds CHF 441.65 employee AHV/IV/EO (5.3%), and pays CHF 441.65 employer share. Annual AHV/IV/EO outlay on the Bitcoin salary: CHF 5,300 employee + CHF 5,300 employer = CHF 10,600 total.

One-off Bitcoin bonuses follow the same rule. AHVG Art. 5 Abs. 2 names Gratifikationen and Naturalleistungen as part of the massgebender Lohn, so the CHF value at the time of payment joins the AHV base.

Mining Income Classification

Mining rewards are taxable income in every case (ESTV working paper 2021, ch. 2.3). AHV liability is a separate question: contributions attach only to Erwerbseinkommen (AHVG Art. 4 Abs. 1), so mining creates an AHV bill only when the activity counts as self-employment. AHVG Art. 9 and AHVV Art. 17 govern; Merkblatt 2.02 explains the criteria.

The Ausgleichskasse asks whether you act in your own name and for your own account, in an independent position, bearing your own economic risk: investments, own equipment, collection risk, rent. Free organisation of the work and several clients point the same way. The tax authority's assessed income figure binds the Ausgleichskasse (AHVV Art. 23 Abs. 4); the status decision is the Ausgleichskasse's own, made per case and per activity on the economic facts.

A small home setup run without a business organisation is usually not self-employment. There is no published size threshold. Someone declaring mining revenue as business income and deducting electricity and hardware as business expenses has already accepted the self-employment classification, AHV consequences included, because the Ausgleichskasse takes the self-employment income straight from the tax assessment (AHVV Art. 23).

The ESTV and the Ausgleichskasse do not always reach the same answer, because only the income and capital figures bind, not the status. If you mine at a scale that produces meaningful revenue, get written confirmation from your Ausgleichskasse before year-end. Do not assume private treatment.

Staking Rewards Classification

The primary source is the ESTV working paper "Kryptowährungen und ICOs/ITOs" of 14 December 2021, ch. 2.3. It speaks to income tax, and AHVV Art. 23 Abs. 4 binds the Ausgleichskasse to the tax authority's income figures.

Pool-staking rewards of a private investor are income from movable assets under DBG Art. 20 Abs. 1. That is not earned income, so no AHV attaches. A solo validator is checked for self-employment; if the check comes out positive, the rewards are self-employment income under DBG Art. 18 and AHV-pflichtig under AHVG Art. 9 and AHVV Art. 17.

No BSV or Ausgleichskasse publication addresses staking specifically. Your Ausgleichskasse is the right place to get a written answer. Do not declare staking rewards as AHV-exempt on the strength of online commentary, including this post.

Self-Employed Sliding Scale

AHVG Art. 8, AHVV Art. 21 and AHV Merkblatt 2.02 define the self-employed contribution structure. The sliding scale is the feature that sets self-employment apart from salaried employment.

Below CHF 10,100 net income you pay the minimum contribution of CHF 530 (AHV 435, IV 70, EO 25). Two exceptions: side-line self-employment up to CHF 2,500 a year is charged only on request, and if you already paid the minimum on a salary, only the lowest scale rate of 5.371% applies (AHVG Art. 8 Abs. 2).

From CHF 10,100 the combined rate climbs in steps from 5.371% to 9.321% just below CHF 60,500. From CHF 60,500 the full 10.0% applies to the whole net income.

Above CHF 60,500 there is no cap. AHV has no upper earnings limit, no maximum contribution, no insured-earnings ceiling. The full rate runs on all net income.

Net income for AHV is not the tax figure unchanged. The Ausgleichskasse adds your own AHV/IV/EO contributions back to the taxed net income (AHVG Art. 9 Abs. 4) and deducts interest on the equity invested in the business (Abs. 2 lit. f). Electricity and hardware depreciation stay deductible as Gewinnungskosten and Abschreibungen (Abs. 2 lit. a and b).

Example. A full-time Bitcoin miner with CHF 80,000 net mining income after electricity and hardware costs sits above the sliding scale. You owe 10.0% on the full CHF 80,000, about CHF 8,000 a year, plus the administration-cost contribution of up to 5% of that. Provisional Akontobeiträge are based on the income you expect for the year (AHVV Art. 24), billed quarterly.

If your Bitcoin income swings hard year to year, tell the Ausgleichskasse when income drops materially mid-year. You are obliged to report a material change (AHVV Art. 24 Abs. 4), and the Ausgleichskasse adjusts the provisional bill. Overpayment comes back after the definitive settlement, but the timing hits your cash flow.

AHV Contribution Timing

AHVG Art. 14 governs timing; AHVV Art. 34 sets the periods. For employees, the employer deducts AHV/IV/EO on each payroll run and remits quarterly if the annual payroll is CHF 200,000 or less, otherwise monthly, within 10 days after the period end.

For self-employed persons, the Ausgleichskasse bills provisional Akontobeiträge on the income you expect for the current year (AHVV Art. 24). It may start from your last assessed figure unless you show that figure is obviously wrong. The four instalments are due 10 days after each quarter end: 10 April, 10 July, 10 October and 10 January. The definitive contributions are set later from the tax assessment (AHVV Art. 23), usually one to two years on. Shortfalls trigger a supplementary bill, payable within 30 days; overpayments come back.

If your 2025 Bitcoin income hit a new high, your 2026 provisional bills will start from the 2025 level unless you tell the Ausgleichskasse your expected 2026 income. If 2026 income drops, a report mid-year stops unnecessary cash outflow. If 2026 income climbs higher, the definitive settlement will show a gap.

Thresholds That Change the Answer

Four 2026 figures from the BSV sheet of 6 November 2025 decide whether a small Bitcoin income triggers contributions at all.

• Geringfügigkeitsgrenze: CHF 2,500 per employer and year (AHVV Art. 34d). Below that, contributions are collected only on request. The same limit applies to a side-line self-employment.
• Freibetrag after the Referenzalter: CHF 16,800 per year, CHF 1,400 per month (AHVV Art. 6quater). A working pensioner pays AHV only on Bitcoin salary or self-employment income above that.
• BVG Eintrittsschwelle: CHF 22,680. A Bitcoin salary above it puts the employee into the occupational pension scheme.
• BVG Koordinationsabzug: CHF 26,460; obere Limite CHF 90,720. These bound the insured salary in the second pillar.

Practical Examples

Example A: Product owner, CHF 100,000 salary fully in Bitcoin

Each month the employer transfers the BTC equivalent of CHF 8,333. AHV/IV/EO deductions:

• Employee share: 5.3% of CHF 100,000 = CHF 5,300 deducted from salary over the year
• Employer share: 5.3% of CHF 100,000 = CHF 5,300 paid by employer
• Total AHV/IV/EO on this salary: CHF 10,600

The Bitcoin denomination triggers no adjustment. The employer's payroll system runs the standard Swiss deduction logic against the CHF-equivalent gross. ALV at 1.1% each side applies on the same CHF figure.

For DCA strategy considerations: if you sweep the after-tax, after-AHV Bitcoin salary straight into a DCA cold storage position, the standard cold storage workflow handles the rest.

Example B: Full-time miner, CHF 80,000 net mining income

Above the sliding scale threshold of CHF 60,500. The full self-employed rate of 10.0% applies to the full CHF 80,000, about CHF 8,000. Quarterly Akontobeiträge go to your Ausgleichskasse, based on the income you expect for the year; the definitive bill follows the tax assessment.

For the income tax treatment of this same CHF 80,000 (wealth tax on end-of-year Bitcoin holdings at the Verkehrswert, income tax on mined BTC at receipt-date CHF value), see Bitcoin Tax in Switzerland and Home Bitcoin Mining 2026.

Electricity and hardware depreciation that bring the gross down to CHF 80,000 net are deductible for both income tax and AHV. The AHV base is net profit, not gross revenue, after the add-back of your own contributions and the equity-interest deduction described above.

VAT and Bitcoin Salary

Paying salary in Bitcoin does not trigger VAT on the transfer itself. ESTV MWST-Info 04 Steuerobjekt, Ziff. 2.7.3.3, in force since 1 June 2019, treats the use of a payment coin for a supply like the use of legal tender, and handing it over is no additional supply. On top of that, MWSTG Art. 18 Abs. 2 lit. j says remuneration for dependent work is not consideration for a supply, and Art. 10 Abs. 1bis makes only an independent activity entrepreneurial. The Bitcoin transfer settles a salary obligation; it is not a commercial sale.
