Sound familiar?

If your books and taxes are a running source of stress, you are not alone.

The problem

  • Receipts in a shoebox and a spreadsheet you have stopped trusting
  • Bookkeeping months behind, so you never really know where you stand
  • A tax bill that arrives as a shock every spring
  • An accountant you hear from once a year, if that
  • Payroll and GST/HST notices you dread opening

How we fix it

  • We clean up and catch up your books, then keep them current
  • Your financial statements reach you every month, on time, or your money back
  • GST/HST, payroll, T4, T5, T4A, corporate tax, and personal tax all handled
  • One fixed monthly fee, agreed up front, with questions always included
  • Tax is planned through the year, not discovered in April

One Monthly Fee

One fixed fee a month. This is what it covers.

Agreed before we start and based on your business. No hourly billing, no surprise invoices, and calls and questions are always included.

Included every month

  • Your books kept current and reconciled
  • Your financial statements, sent to you every month
  • GST/HST prepared and filed
  • Payroll run, with T4, T5, and T4A slips filed
  • Corporate tax return prepared and filed
  • Personal tax return filed on time

Our Guarantee

Your financial statements every month, on time, or your money back.

After each month closes, your financial statements reach you before the end of the next month. Every month. If we ever miss that window, that month is free.

I had the pleasure of working with Amirhossein on our bookkeeping, corporate tax filings, and GST/HST returns. He was highly professional, responsive, and always delivered everything on time. What impressed me most was his attention to detail and deep knowledge of tax regulations. He identified several opportunities for tax credits and savings that our previous accountant had never mentioned, which ended up saving our business a significant amount of money.

I highly recommend Mir Financial Services for anyone needing expert assistance with complex tax situations. They have been instrumental in our tax planning, especially when navigating the distinct rules between short term and long term rental properties. Their deep knowledge of capital gain rules and HST implications took a huge weight off our shoulders. If you want an accountant who truly understands real estate and strategic planning, look no further!
