PENALTIES FOR NOT FILING A T1135
The penalty for not filing a T1135 results in an automatic penalty, whether or not the taxpayer knew of the filing obligations. The penalty starts at a minimum of $100, but is calculated at $25 per day for up to 100 days. The maximum penalty for each tax year is $2,500. In addition to this automatic penalty, the CRA may also choose to assess gross negligence penalties against a taxpayer. These are much more harsh and consist of $500 per month for a maximum of 24 months, or a total of $12,000. Penalties again increase if you’ve been contacted by the CRA and have received a demand to file a return. The penalties at this point increase to $1,000 per month for a maximum of 24 months, or a total of $24,000. The penalty for making false statements or failing to report required information on a T1135 is not applied automatically, but only where the taxpayer is grossly negligent. The penalty amount is the higher of 5% of the cost of the specified foreign property or $24,000.
If you have failed to file or have filed an incorrect or incomplete T1135 forms in the past, all is not lost. You can use the CRA’s Voluntary Disclosure Program to make up for past shortcomings and avoid penalties that would otherwise apply. There are some preconditions to being able to access this program and benefit from the penalty relief it provides.
