MONTREAL -- Many Canadians live frugally for years in the hope of leaving large legacies to their children, but without proper estate planning those legacies can be fraught with complications.

Taxes, real estate passed down and now shared by siblings, and questions about how to best manage a sizeable inheritance can leave people facing issues they've never encountered and are ill-prepared to handle.

It's an issue that's attracting increased attention as Canada's population ages and an estimated $1 trillion is passed along in inheritances.

While beneficiaries don't pay inheritance taxes, settling estates can be daunting tasks for children who are named executors and have to determine how much income taxes and probate fees are owed.

For instance, years of pinching pennies, even by those who survive the poverty line in their later years, can amass sizeable enough portfolios to push them into the highest income tax bracket after death.

"That happens all the time if you've got a $100,000 or more RRSP and you're not leaving it to a spouse,'' says Christine Van Cauwenberghe, assistant vice-president tax and estate planning at Investors Group.

A person's estate not only includes their annual income, but also unsheltered investments, registered investments and secondary properties.

"That's why you need to do tax planning because there could be a major tax bill in the year of death.''

Determining what to do with inheritances can pose its own challenges, especially if they are of a magnitude that can be life-altering.

"The first thing we tell clients when they receive a large sum of money is just to take a deep breath and not do anything rash,'' Van Cauwenberghe said from Winnipeg.

Some people are not used to dealing with large sums of money or haven't been successful in managing their own finances.

The tendency is for these people to quickly make large purchases, undermining the ability for the inheritance to generate a higher standard of living or allow the recipients to fulfil their dreams.

Van Cauwenberghe recommends that people put the money in some sort of short-term liquid fund like a GIC or money market for up to several months while they develop a plan that will incorporate the newly acquired money into their own financial plan.

"When money comes in you may want to just park it, it's the same advice we give lottery winners,'' adds Jamie Golombek, managing director tax and estate planning at CIBC Private Wealth Management.

Ultimately, the plan may be as simple as paying down debt including a mortgage, buying RESPs, topping up RRSPs and buying a tax-free savings account.

But it becomes more complicated with real estate. Do you sell or rent the family home or cottage? Can you get agreement from siblings who may have a different point of view?

Inheriting stocks can pose their own challenges if the recipient already has a large concentration in the same companies.

The key is to have a good financial plan, he said.

"If a sudden inheritance comes in it will be much more obvious where that money should be allocated and whether or not you should be liquidating stocks, real estate, etc.''

Proper planning is also required for those in shaky relationships. Inheritances typically aren't split upon a couple's divorce, but the exemption can be lost if the money is used to pay down the mortgage of the matrimonial home or put into a joint account.

Some of these people are even loathe to end their relationships until they receive the financial security that accompanies an inheritance, Van Cauwenberghe added.

Anecdotally, she said those who make the most of their inheritances tend to have a financial planning ethic ingrained in the family.

"If you've been good with managing money before, chances are you will be good with managing money after, perhaps there's just an extra zero or two at the end.''

Inheriting money can also prompt beneficiaries into finalizing their own inheritance plans and wills, especially since insurance can make even a young family worth more dead than alive, she added.

A recent CIBC survey found that almost half of respondents had not created a will and nearly half of those people thought they were too young or didn't have enough assets. This included almost one-third of Baby Boomers aged 45 to 64 and 10 per cent of seniors.

Failure to have a will forces a situation in which an estate is administered in accordance with provincial law, which could reduce entitlements to a surviving spouse in favour of children.

A will could also establish trusts for minors and young adults that stagger inheritance payments to later in life instead of giving a lump sum at the age of majority when rash decisions are more likely to occur.

Proper estate planning could also reduce probate taxes -- 1.5 per cent of an estate value in Nova Scotia, Ontario and B.C. -- by rolling over RRSPs to qualified beneficiaries, and deferring income taxes by taking advantage of a spousal rollover.

  • The Children's Arts Tax Credit

    This new credit was a budget measure that was designed to address criticism that the earlier Children's Fitness Tax Credit (which is still in effect) unfairly left out parents who paid for programs where the kids had to do more thinking than sweating. It provides a 15 per cent non-refundable federal tax credit on the first $500 spent on your kids' artistic, musical, recreational or cultural development in 2011. That means the tax credit is worth a maximum of $75 per child. Parents of disabled children can claim a 15 per cent tax credit on the first $1,000 of eligible spending, or a maximum of $150. To get the credit, children must be under 16 at the start of the year in which the program is taken (under 18 in the case of disabled children). To qualify, a program must be at least eight consecutive weeks in length, or, in the case of children's camps, at least five consecutive days. Receipts are a must.

  • The Volunteer Firefighter's Tax Credit

    If you performed at least 200 hours of service as a volunteer firefighter in 2011, you can see your tax bill reduced by up to $450 - another new non-refundable tax credit introduced in last year's federal budget. That's the net effect of a 15 per cent tax credit on the $3,000 volunteer firefighters' amount. The 200 hours doesn't have to be entirely spent fighting fires. Attending required meetings and training also qualify. Be aware that there's a big wrinkle in this tax credit for those who get an honorarium for their volunteer efforts. Currently, the first $1,000 of that honorarium is exempt from tax. But if you claim that income exemption, you won't be eligible for the volunteer firefighter's tax credit. No documents need to be filed, but the CRA says it may require claimants to provide certified proof that they actually do qualify.

  • Family Caregiver Tax Credit

    This measure doesn't actually take effect until the 2012 tax year, so you won't benefit from it when filing this year. But people who will eventually benefit can file a new TD1 Personal Tax Credits Return with their employers now to reduce their withholding tax for the remainder of 2012. This credit amounts to an increase of $2,000 in the claim when a taxpayer's dependent is physically or mentally infirm. So the spouse, common-law partner or other eligible dependent claim becomes $12,780 instead of $10,780. Similarly, the claim for a disabled child becomes $4,191 rather than $2,191. The caregiver amount claim for looking after an infirm relative also goes up by $2,000.

  • TFSAs

    Tax-free savings accounts were first unveiled in the 2008 federal budget and have continued to grow in popularity - in part because Canadians can put more money into them each year. If you haven't yet contributed to a "Tiff-sa," the available contribution room rose by $5,000 on Jan. 1, 2012 and now stands at $20,000. TFSA contributions can go into GICs, mutual funds, bonds, stocks or savings accounts and earn profit tax-free, but keep in mind they don't work like a bank account with a maximum balance. When you withdraw funds in one year, TFSA rules don't let you redeposit that amount until the next. In 2009, about 70,000 people withdrew money from one of their TFSA accounts and then redeposited it the same year, so the Canada Revenue Agency levied penalties of one per cent per month on redeposits that were classed as excess contributions. The government eventually relented because of the widespread confusion, and rescinded the penalties in 2010 for people who accidentally put too much into their accounts during the TFSA's debut year. The amnesty is over now, however, and savers can't expect that kind of pity from the tax collector anymore. If you want to move your money from one account or institution to another within the same calendar year, you have to use a formal transfer process that requires filling out forms and, with most banks, paying a fee.

  • Changes That Affect Students

    As of the 2011 tax year, examination fees now qualify for the tuition tax credit. That is, as long as the total fees, including exam fees, amount to at least $100 and the exam is required to obtain professional status or to be licensed or certified in a profession or trade. For students enrolled full-time in a university outside Canada, the minimum length of course that qualifies for tuition, education and textbook tax credits has been lowered from 13 weeks to three weeks. The 2011 budget also loosened the restrictions on transferring investments held in one sibling's Registered Education Savings Plans (RESP) to another sibling's RESP. Under the old rules, transferring RESP investments property from one sibling's plan to another's could trigger a repayment of the Canada Education Savings Grant unless the sibling receiving the transferred investment is under the age of 21. But transfers occurring in 2011 and after will not trigger grant repayments as long as the receiving RESP was set up before the beneficiary turned 21.

  • Medical Expenses And An RDSP Change

    As of 2011, the maximum medical expense claim of $10,000 for a dependant relative (other than for a spouse, common-law partner or a minor child) has been eliminated. Now, there's no limit. The last budget also made a change to the rules governing Registered Disability Savings Plans (RDSPs). Under the old rules, all grants and bonds paid into the plans in the previous 10 years had to be returned to Ottawa if a disability assistance payment was made to an RDSP beneficiary. Now, no repayment is necessary if a doctor certifies that a plan recipient isn't likely to survive for five years

  • Changes To Federal Tax Brackets And Credits

    Most tax brackets and credit amounts were raised in 2011 to account for inflation. In the case of federal tax brackets, they have been raised by 1.4 per cent from 2010's levels. Most of the basic personal amount claims have also been boosted by 1.4 per cent. The 2011 TD 1 tax forms and all of the software and online tax programs reflect the new amounts. Similarly, the thresholds at which some benefits begin to get clawed back (like Old Age Security payments) have been raised by 1.4 per cent. Some refundable tax credits, like the Canada Child Tax Benefit, have also been boosted by 1.4 per cent. Many provinces and territories have also boosted their personal tax credits by indexing factors ranging from 0.8 per cent to 2.0 per cent. But two provinces - Nova Scotia and Prince Edward Island - made no changes in their personal tax credit amounts.
