General Contractors in Windsor, books handled

Windsor's cross-border, trades, and service businesses need bookkeeping that keeps up and a Canadian accountant standing behind every filing.

For general contractors specifically, taxifi covers the work below as part of one flat monthly price, with Ontario’s HST, WSIB, and Employer Health Tax handled inside the service:

  • Progress-billing and holdback tracking
  • T5018 subcontractor slips prepared and filed
  • Crew payroll and WSIB-ready records
  • HST input tax credits on materials and equipment

What we take off a Windsor general contractor’s plate

Holdbacks and progress draws

Construction holdbacks distort what you think you've earned. We track them so your revenue and receivables reflect what you're actually owed and when.

T5018 subcontractor reporting

Every sub payment is tracked through the year and the T5018 slips are prepared and filed on time, with records behind each number.

HST across materials and equipment

Input tax credits on materials, rentals, and equipment are captured on every transaction so your net HST is accurate.

Why Windsor general contractors choose taxifi

Windsor's economy moves to an automotive and cross-border rhythm — manufacturing and the supply chains around it, major new electric-vehicle-related investment reshaping local demand, and Detroit five minutes away. Border-city business is real business, and it puts a premium on books that are actually current.

Layer onto that what general contractors deal with everywhere — holdbacks, progress draws, and a bench of subs spread across multiple active jobs — and the case for taxifi is simple: books kept current daily by AI, filings reviewed and signed by a Canadian accountant, and every job closes with its true margin on record instead of a best guess.

Common questions

How do construction holdbacks work for tax purposes?

Ontario's Construction Act requires a 10% holdback on construction contracts, and holdbacks have their own timing for tax — notably, HST on a holdback amount is generally not due until the holdback becomes payable, not when you first invoice. Books that track holdbacks separately keep that timing right automatically; books that don't overpay early or underpay late.

Which of my subcontractors go on T5018 slips?

For a business whose primary activity is construction, payments to subcontractors for construction services get reported on T5018s — incorporated or not, which catches people used to the T4A rules. taxifi keeps a running record of every sub payment on every Windsor job, so slip season is an export rather than an archaeology dig through e-Transfers.

Some of my customers and suppliers are in Michigan. Does that complicate my books?

It can — cross-border revenue, US-dollar transactions, and non-resident customers each have their own treatment, and the right answers depend on your specific situation. taxifi keeps the Canadian books clean and current, and the accountant flags and scopes the cross-border questions before they become filing-season surprises.

I already have a bookkeeper or accountant in Windsor. How hard is switching?

The switch is free: we deal with your current provider directly, collect your file and history, and take over the monthly work. Any catch-up is scoped and priced before you commit. Your part is about an hour, and mid-year is fine.
