What Norway Payroll Base Amounts is for

Gives the 2026 employer's National Insurance contribution (arbeidsgiveravgift) rate for each of the seven Skatteetaten zones and both sector columns as the Skatteetaten rate page prints them, turns a pay figure into the contribution at the printed rate as plain arithmetic, states the printed zone Ia allowance rule, and reads the current National Insurance basic amount (G) from the keyless NAV JSON API with its effective dates, with a dated offline fallback. It does not decide which zone applies to a municipality or which pay counts. General information about published rates, not tax advice.

Ask your assistant things like:

• "What are the 2026 employer contribution rates for each Norwegian zone?"
• "What is the employer contribution rate in zone II for agriculture and fishing?"
• "What is the employer contribution on NOK 500 000 of pay in zone III?"
• "How does the zone Ia allowance work and where is it used up?"
• "What is the current National Insurance basic amount G?"

What it does

• zones_table: All seven zones (I, Ia, II, III, IV, IVa, V) with the ordinary-industries and agriculture-and-fishing rates as printed for 2026 and the zone Ia footnote.
• employer_contribution_rate: Rate in percent for a zone and a sector column as printed; refuses an unknown zone.
• contribution_amount: Pay in NOK times the printed rate as plain arithmetic; for zone Ia ordinary the printed 14,1 percent is shown and the allowance rule is pointed to.
• zone_ia_allowance: The printed zone Ia rule: 10,6 percent until the difference between contribution paid and contribution at 14,1 percent equals the allowance (NOK 850 000 per enterprise in 2026), 14,1 percent on the rest; optional cumulative base for the plain-arithmetic split.
• get_basic_amount: Live NAV answer: G, per month, yearly average, conversion factor, effective date and the date minimum income applies from; offline fallback with its date.
• basic_amount_multiples: n times G and G per month as arithmetic, with the effective date.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Norway Payroll Base Amounts — Privacy Policy

Effective 29 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Norway Payroll Base Amounts is. Norway Payroll Base Amounts is a connector (an MCP server and REST API) that AI assistants call on your behalf: Employer contribution rate by Skatteetaten zone and sector for 2026, zone Ia allowance, and the NAV basic amount G. You talk to your assistant; the assistant sends us only the arguments needed for that one request.

What we receive. The arguments of each tool call, the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Nothing is stored. Some tools ask the public sources listed in the documentation for data. Only the arguments needed for that one lookup are sent, never anything that identifies you. Arguments are used for that one response and are not logged in request bodies, recorded, or used to train anything.

What we do not receive or store. We do not receive your conversation with the assistant, your name, contacts or account credentials, and we build no profile: each request is answered independently. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses and request paths, not request bodies) are kept for up to 30 days for security and abuse prevention.

Sub-processors. Public data sources named in the documentation (no personal data is sent to them). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information.

Children. Norway Payroll Base Amounts is a general-audience service operated by the adult using the assistant.

Changes. We will post changes here with a new effective date.
