Tax Manager | Gestionnaire en Fiscalité

Position Summary
We're looking for a Tax Manager to own tax for the companies Ventures builds. You'll set each new company up correctly from the start, keep it compliant as it grows, and build the process every future venture follows. The work centres on Canada and the U.S., with filings elsewhere coordinated through local advisors as ventures enter new markets. The role is based in Montreal.
AI should be part of how you work. Use it to research, draft, analyze, and automate. You're responsible for the quality of the result.
Values
Sound judgment and attention to detail.
Taking responsibility and finishing work without being chased.
Understanding how a young company makes money and how tax follows it.
Curiosity and a willingness to change an approach that isn't working.
The honesty to say when a position isn't defensible, including your own.
What you'll do
Set up each new venture correctly
When Ventures decides to build a company, you'll work out what tax needs to be in place before it takes its first customer: structuring input, registrations, elections, and how its products and pricing are taxed. You'll work with the founder in residence, Valsoft's finance and legal teams, and the VP, Tax on structuring decisions.
A venture that starts with the wrong registrations or an untested sales tax position carries that into every invoice. You'll make those calls early, document the positions you take, and build a setup checklist so each new venture starts faster than the last.
Run compliance across the ventures
You'll manage Canadian federal and provincial corporate income tax returns and U.S. federal and state income and franchise tax returns for each venture, reviewing what external providers prepare. You'll keep a tax calendar, records, and audit files for every company, and resolve notices and correspondence from the CRA, Revenu Québec, the IRS, and state authorities.
As ventures enter other markets, you'll coordinate corporate and indirect tax filings with local advisors and decide when a venture needs its own registrations there.
Own sales and indirect tax
You'll own U.S. sales and use tax for the ventures: nexus monitoring, registrations, taxability analysis, filing, and remittance. In Canada you'll manage GST/HST and QST, including registrations, returns, and input tax credit and input tax refund recovery.
You'll work with each venture's finance and billing setup so customer invoices charge the right tax in each jurisdiction, and keep exemption certificates and supporting documentation ready for audit. Early customers often come through Valsoft's portfolio businesses, so a wrong tax charge lands on a relationship the venture depends on.
Handle intercompany and group reporting
Ventures run on Valsoft's capital, infrastructure, and support, which means intercompany arrangements from the first day. You'll set up and document those arrangements, coordinate transfer pricing documentation with external advisors in line with CRA, IRS, and OECD guidelines, and support any inquiries.
You'll prepare tax provisions under IFRS, including current and deferred tax and uncertain tax positions, and give Valsoft's corporate tax team its group inputs: T106 and T1134 foreign reporting, associated corporation schedules, country-by-country reporting, and Pillar Two data.
Build the tax process Ventures runs on
You'll design the processes, controls, and tools that let tax keep up as the number of ventures grows, and decide where a tax engine or automation is worth adding. Founders, finance, and legal will treat you as their main contact on tax, and you'll explain requirements in plain terms.
You'll give tax input on new products, pricing models, market entry, and partnership arrangements, summarize legislative changes that affect the ventures, and support the VP, Tax on structuring as a venture grows into an independent business.
What you'll bring
A CPA designation (Canada or U.S.).
At least 4 years of post-designation tax experience in public accounting or a corporate tax environment, with exposure to both Canadian and U.S. tax.
Working knowledge of transfer pricing, international tax, and tax accounting under IFRS.
You can look at a new business model and work out what tax it triggers before it launches.
You prepare, review, and file returns yourself.
You manage external advisors and hold them to deadlines and quality.
You can give a founder a clear tax answer they can act on the same day.
You use AI to research, draft, and analyze, and you check the output before it goes anywhere.
You work independently and keep several companies' calendars moving at once.
You finish what you start and keep records an auditor can follow.
Useful experience
Hands-on U.S. sales and use tax compliance
Canadian GST/HST and QST compliance
Tax for startups or newly formed entities
Sales tax treatment of software and SaaS
Voluntary disclosures
Working in a group with many subsidiaries
Bilingual
Who will enjoy this role
You like getting something right before it becomes a problem. A founder mentions a new pricing model on Monday, and by Wednesday you've worked out where it creates nexus and what the invoice needs to say.
In one week you might register a new entity, review a U.S. state return for an older venture, and walk a founder in residence through what QST means for their first Quebec customer.
The hard part is that every venture is different and none of them waits for tax. Founders move fast, priorities shift when a venture changes direction, and you'll often set up a company whose product isn't finished yet.

Sommaire du poste
Nous cherchons une personne gestionnaire en fiscalité pour prendre en charge la fiscalité des entreprises que bâtit Ventures. Vous mettrez chaque nouvelle entreprise sur pied correctement dès le départ, veillerez à sa conformité à mesure qu'elle grandit et bâtirez le processus que suivra chaque future entreprise. Le travail porte surtout sur le Canada et les États-Unis. Les déclarations ailleurs sont coordonnées avec des conseillers locaux à mesure que les entreprises entrent dans de nouveaux marchés. Le poste est basé à Montréal.
L'IA devrait faire partie de votre façon de travailler. Servez-vous-en pour faire de la recherche, rédiger, analyser et automatiser. Vous êtes responsable de la qualité du résultat.
Ce qui compte pour nous
Un bon jugement et le souci du détail.

Ce que vous ferez
Mettre chaque nouvelle entreprise sur pied correctement
Quand Ventures décide de bâtir une entreprise, vous déterminez ce qui doit être en place sur le plan fiscal avant qu'elle serve son premier client : conseils sur la structure, inscriptions, choix fiscaux et traitement fiscal de ses produits et de sa tarification. Vous travaillerez avec le fondateur en résidence, les équipes Finances et Affaires juridiques de Valsoft, et le vice-président, Fiscalité sur les décisions de structure.
Une entreprise qui démarre avec les mauvaises inscriptions ou une position non validée en matière de taxes de vente reporte l'erreur sur chaque facture.

Assurer la conformité de toutes les entreprises
Vous gérerez les déclarations de revenus fédérales et provinciales des sociétés au Canada, ainsi que les déclarations fédérales et d'États (impôt sur le revenu et franchise tax) aux États-Unis, pour chaque entreprise, en révisant ce que préparent les fournisseurs externes. Vous tiendrez un calendrier fiscal, des registres et des dossiers de vérification pour chaque société, et réglerez les avis et la correspondance de l'ARC, de Revenu Québec, de l'IRS et des autorités des États.
À mesure que les entreprises entrent dans d'autres marchés, vous coordonnerez les déclarations d'impôt sur le revenu et de taxes indirectes avec des conseillers locaux, et déciderez à quel moment une entreprise doit s'y inscrire.
Prendre en charge les taxes de vente et les taxes indirectes
Vous serez responsable de la sales and use tax américaine pour les entreprises : suivi du lien fiscal (nexus), inscriptions, analyse de l'assujettissement, production des déclarations et versements. Au Canada, vous gérerez la TPS/TVH et la TVQ, y compris les inscriptions, les déclarations ainsi que la récupération des crédits de taxe sur les intrants (CTI) et des remboursements de la taxe sur les intrants (RTI).
