Services we offer:

Personal income taxes — we offer full-service personal income tax filing. While it has become popular in recent years for individuals to do their own taxes, there are many good reasons why you might want to hire a professional from Grenning & Co. If you are self-employed or earn commission, rental income or income from some other investment, you are likely to benefit from the expertise of a tax professional. Our accounts can also help you plan for future tax returns.

Corporate tax returns — In additional to personal returns, we also offer corporate returns for small to medium sized enterprises including non-profits. This is a great benefit to businesses in the local area who may not be able to afford a separate accounting department but still require expert advice.

Monthly bookkeeping — Grenning & Co. provides monthly bookkeeping services to many of our corporate clients. This includes reconciling bank statements, preparing HST and WSIB reports as well as providing copies of balance sheets, income statements and journal entries.

Payroll services — Our firm provides a complete range of payroll services including making sure that compensation is up to date and that bonuses and commission are properly calculated and that missed work and vacation time are also documented in a timely manner. We can also help you manage payroll records such as T4s and records of employment.
