About Ontario Sales Tax

Ontario has a 13% combined sales tax rate, consisting of the 5% federal GST and 8% provincial HST.

Ontario uses the Harmonized Sales Tax (HST) system. The HST combines the 5% federal GST and the provincial portion into a single streamlined rate administered entirely by the Canada Revenue Agency. Businesses file one return, claim one set of input tax credits (ITCs), and remit to one authority — significantly simplifying compliance compared to dual-tax provinces.

What Postal Code K4B Covers

K4B covers Navan and the rural villages of eastern Ottawa. The Navan Fair, running since 1937, is one of the larger agricultural fairs in eastern Ontario. The area remains working farmland inside the city's boundary, a legacy of the 2001 amalgamation that brought extensive rural townships into Ottawa.

Where K4B Sits — and What That Changes at the Till

K4B sits about 20 km east of Ottawa, the nearest centre of any size, and is the only postal area our data records for Navan. Its closest postal neighbours are K1W (Ottawa (Orléans)) about 6 km off and K4A (Ottawa (Orléans)) about 8 km off.

The nearest postal area we hold in another province is J8M (Gatineau (Masson-Angers), Quebec), about 15 km from K4B. A $500 order delivered into K4B carries $65.00 in HST; the same order delivered into J8M carries $74.88 in GST + QST$9.88 apart on one invoice. Because Canadian sales tax follows the customer, a seller in Navan shipping to both charges 13% on the first and 14.975% on the second, from the same warehouse on the same day.

4 named communities share this one code — Navan and Vars among them — which is the ordinary shape of rural Ontario: the postal geography is wide, the retail geography is narrow. General merchandise is bought in one or two service centres or ordered in, and an order shipped into K4B takes 13% however far the seller sits from Navan. Around Rural east Ottawa farmland, the HST picture inverts the usual one: most bulk farm products a producer sells are zero-rated, and so are many of the inputs — seed, bulk feed, fertiliser, and equipment above the CRA's thresholds. Repairs, utilities and professional services are not, so a farm's biggest transactions can carry nothing while its overheads carry 13%.

The 13% above is set for the whole of Ontario and does not move between postal codes — K4B pays exactly what every other Ontario code pays. Navan is inside Ottawa for tax purposes, and overnight accommodation is where Ottawa parts company with the rest of Ontario. The municipality levies a 6% Municipal Accommodation Tax on top of HST, so a $200 room night inside K4B carries $12.00 that the identical room would not carry in an Ontario municipality that never adopted one. The boundary is the amalgamated one, so Kanata, Nepean, Gloucester and Orleans are inside it exactly as downtown is.

Everything above is particular to K4B; the rules that are not — registration thresholds, filing frequency, input tax credit recovery, point-of-sale rebates — are set for the whole of Ontario, and they live on the Ontario sales tax guide rather than being restated on K4B's page, where the calculator above is already locked to 13%.

Selling into K4B: What You Need to Register For

Ontario runs a HST system administered by Canada Revenue Agency (CRA), with a registration threshold of $30,000 (HST). Filing frequency, input tax credit recovery, point-of-sale rebates and the full registration walkthrough are set out on the Ontario sales tax guide — they are province-wide rules, identical for every postal code here, so this page links them rather than repeating them.

  1. Charge the rate the address decides. A delivery into K4B is an Ontario sale, so charge 13% HST — your own address does not enter into it.
  2. Show it the way Canada Revenue Agency (CRA) expects. One HST line and the total tax amount on each invoice.

Everything else about selling here — thresholds, filing frequency, ITC recovery, point-of-sale rebates, and the full province-by-province sourcing rules — is identical for every postal code in Ontario and is set out once on the Ontario sales tax guide and in the Ontario GST/HST calculator.

Frequently asked questions

Quick answers to the most common questions users ask.

What areas does postal code K4B cover?

The Forward Sortation Area K4B covers Navan, Vars, Sarsfield and Bearbrook in the Rural east Ottawa region of Ontario, serving about 8,000 in a predominantly rural setting. Retail and civic landmarks inside the code include Navan Fair, Rural east Ottawa farmland and Bearbrook — the places where purchases in K4B actually happen.

What is the sales tax rate for FSA K4B in Ontario?

The combined sales tax rate for postal code FSA K4B in the Navan area of Ontario is 13%. This is a Harmonized Sales Tax (HST) that combines the 5% federal GST with an 8% provincial component into a single rate administered by the Canada Revenue Agency.

How do I calculate tax for a purchase in Ontario (FSA K4B)?

To calculate the total price including sales tax for any purchase in Ontario, multiply the purchase price by 1.13. For example, a $100.00 purchase costs $113.00 total, with $13.00 in sales tax.

For the reverse calculation, divide the total price by 1.13 to find the pre-tax amount. Run the example above backwards and $113.00 paid in Ontario resolves to $100.00 before tax and $13.00 of HST.

Does Ontario use HST or separate GST and PST?

Ontario uses a Harmonized Sales Tax (HST) system. The HST combines the 5% federal GST with the 8% provincial component into a single rate of 13%. Businesses file one return with the CRA.

What kind of area is K4B — urban, suburban or rural?

K4B is a predominantly rural code serving about 8,000, within the Rural east Ottawa region. Retail is concentrated in a few centres, so residents frequently buy online or drive to a larger town — both of which are still taxed at the same provincial rate, but delivery-based purchases follow the destination rule to this postal code.

Do local taxes in K4B change what I pay?

Not the sales tax itself — Ontario levies 13% province-wide and there is no municipal sales tax in Canada. What can differ by municipality are the separate levies that sit outside sales tax: accommodation and lodging taxes on short-term stays, and in some provinces local levies on prepared food or alcohol.

So a hotel folio or restaurant bill from Navan can total more than 13% while a retail receipt from the same street does not. Check the municipality's own schedule for those, and see the Ontario sales tax guide for the province-wide rules.

How does FSA K4B map to a sales tax rate?

The Forward Sortation Area (FSA) is the first three characters of a Canadian postal code. K4B falls within the range assigned to Ontario, specifically the Navan area. Canada sets sales tax provincially rather than municipally, so the FSA's job here is to place the buyer: once you know a delivery address sits in K4B, you know it is an Ontario sale and you charge 13%. That matters most for shipped orders, where the buyer's postal code — not your own — decides the rate.
