TrueNorth API Services
Everything on one key
Five new answers joined the sales tax engine TrueNorth started with. Each service is a single call, and each successful answer costs one credit.
Canada
Canada, on the same key
Payroll calculator, Canada
One pay period in, and you get take home pay, every deduction, and your true cost as the employer. Official CRA formulas, and it knows the pay where CPP and EI stop for the year.
See the endpointSales tax, Canada
Exact GST, PST, HST and QST across 41 product categories in all 13 provinces and territories, with per province breakdowns and federal luxury tax on vehicles over $100,000.
See the endpointHolidays and business days, Canada
Statutory holidays for the federal calendar and every province and territory, plus business day checks, so you know the calendar before you promise a deadline or schedule a shift.
See the endpointPostal code intelligence, Canada
A postal code returns more than an address: its community, province, time zone, and the people behind it, from Statistics Canada Census data.
See the endpointBusiness number validation, Canada
Check a business number and look it up against Canada's federal corporations before you sign, ship, or pay. Know who you are dealing with first.
See the endpointAddress validation, Canada
Validate Canadian addresses on your forms and checkouts, and check shipping deliverability before a bad address costs you an order.
See the endpointTen endpoints, documented with live examples on the endpoints page.
Australia
Australia, on the same key
The same key and the same one credit per answer now cover Australia. Seven Australian endpoints are live today, beside the ten Canadian ones.
Payroll, Australia
PAYG withholding for weekly, fortnightly, or monthly pay from the official ATO formulas, with HELP debt withholding, a Medicare levy estimate, super guarantee at 12 percent, and your total cost to employ.
See the endpointGST classification
Classify a product or service into its GST treatment and rate. Food is matched item by item against the ATO Detailed Food List, and the Division 38 and Division 40 rules decide the rest.
See the endpointHolidays and business days, Australia
Public holidays for every state and territory, computed from the governing rules and verified against the published state lists, plus business day checks, additions, and counts.
See the endpointPostcode intelligence
A four digit postcode returns its suburbs, state, coordinates, and time zone, from open G-NAF data covering 3,174 postcodes. You can search by suburb name too.
See the endpointABN validation
Validate an Australian business number against the live register: ABN status, entity name, and GST registration, with the official checksum built in. Nine digit company numbers are recognised as an ACN and checked too.
See the endpointTax categories, Australia
The Australian GST treatments in one list: taxable, GST free, and input taxed, each with its section of the GST Act and whether input tax credits can be claimed.
See the endpointSeven Australian endpoints, documented with live examples on the endpoints page.
And still the deepest Canadian tax engine
Platform tax tools only work inside their own checkout and need manual setup per province. TrueNorth delivers correct Canadian taxes anywhere, with a single call.
