Income Tax Challenges For Law Firm Partners And Sole Practitioners

There are many benefits to launching a solo practice or becoming a partner in a law firm including, potentially, a more flexible work schedule, or the possibility of increased earnings. The one thing most people don’t get excited about is keeping track of all their expenses and planning for their income taxes. But procrastination in handling the financial side of your business can result in frustration, or even panic, as the tax deadline looms.

There are some real tax challenges for sole practitioners and partners:

  • Your income may vary month-to-month making it difficult to estimate annual earnings and thus the appropriate tax rate.
  • A varied income also makes it hard to create a cash flow plan.
  • Even if you create a plan it can be difficult to honour it when cash flow is tight.

Then there are the pitfalls of inexperience:

  • Losing track of receipts.
  • Mixing personal expenses with business expenses.
  • No clear sense of how much to set aside for income taxes.
  • Falling behind and still trying to catch up on last year’s taxes owing.
  • Missing the filing deadline and incurring penalties.
  • Not using a bookkeeper or professional accountant to help with your tax preparation/filing.

So what do you do if you find yourself unprepared for this year’s return?

Set aside time to find and organize as many receipts as you can.

If you don’t have a system of keeping receipts, now is a great time to create one so you will be well organized for next year’s taxes. (It can be as simple as keeping all business expense receipts in envelopes, one for each month of the year, or as fancy as a phone app to take a picture of each receipt, categorize them and upload a report to your bookkeeping software).

You can use your business bank records and credit card statements to confirm you haven’t missed any big expenses, but remember that the CRA or IRS will need the original purchase receipt, a credit card slip alone will not be sufficient in an audit.

Remember to include “business use of home” expenses, such as a portion of your rent/mortgage, utilities, home insurance, cleaning supplies.

If you made any large purchases of equipment or furniture, these need to be identified as capital costs, so separate them into their own category.

If you use your car for business you will need to determine how many kms or miles you drove in total for the year, and how many were for business use, then the same ratio of the expenses related to the car can be used as business expenses.

If all that seems overwhelming, understand that the biggest step is creating the system, it gets much easier once the system is in place. You may want to consider getting help from an accountant, bookkeeper or money coach.

If it turns out that you owe more than you can afford to pay, make sure you file anyway to avoid late filing fees. Then contact a tax services office to arrange a mutually acceptable payment plan.

What can you do differently going forward?

  • Forecast your estimated income and expenses for the year. It can be a challenge, but look at your earnings and expenses from last year and try to extrapolate going forward.
  • Estimate your taxes owing: Once you know your net income (revenue – expenses) you can consult a tax professional, money coach, or use an online calculator to determine your estimated taxes owing.
  • Set up a plan to save monthly towards your taxes. Either a set amount or a % of your revenues could work, as long as you do it! The CRA or IRS may require you to pay your taxes on a quarterly basis going forward, so it is vital that you have that money set aside, so you can avoid late payment interest charges.
  • Be clear on your personal cash flow needs – figure out how much you need each month for business expenses, but also be conscious of how much you can afford to pay yourself from your business income.
  • Pay yourself a regular pay from your business account to your personal account. This will help even out the ups-and-downs of being self-employed.
  • Set-up a system to stay on top of your receipts, bookkeeping, tax payments, payments to yourself… etc.

Avoiding the financial side of your business, at best, creates an energy drain, or at worst can place your in financial jeopardy. Once you have a plan and systems in place, you can reinvest that energy into growing your law practice.
