In Canada, there is no set limit on how long you can go without filing, but you should file within 10 years to ensure the CRA can process your return for refunds or adjustments. While you can go years without filing, failing to do so leads to mounting interest, severe penalties (up to 200% of taxes owed), lost benefits (CCB, GST/HST), and potential legal action or prosecution.
There is no direct financial penalty for late filing unless you owe taxes. However, late payment of amounts owing is subject to a 5% late fee plus 1% for each additional month until payment is made in full. You may also be penalized as the CRA will withhold government benefits until your tax filing is up to date.
If you don't file taxes for five years, you will forfeit all refunds that are over three years old (if applicable). You also put yourself at risk of the IRS assessing interest and penalties against you. The IRS has the ability to file SFRs on your behalf if you are past the filing deadline for a tax return.

There's no official limit to how many years you can go without filing taxes, but the IRS expects you to file if required, and the statute of limitations on the IRS assessing tax or collecting never starts until you actually file, meaning they can pursue unfiled returns from any year, even decades old. While the IRS often focuses on the last six years, waiting increases penalties and interest, and you risk losing any potential refunds after three years; proactively filing past-due returns is always best.
Put simply, this means the federal tax fraud statute of limitations is three years past your filing date. However, if the IRS discovers that over a quarter of your income was omitted on your tax return, the statute of limitations doubles. In other words, the agency has six years to file charges against you.
What happens if you refuse to file taxes? If penalties and interest aren't motivating enough and you outright refuse to file taxes, the IRS can enforce tax liens against your property or even pursue civil or criminal litigation against you until you pay.
Penalties and interest

If you haven't filed taxes in years, gather your financial documents (income statements, receipts) for those years, request wage and income transcripts from the IRS to ensure accuracy, and file all missing returns ASAP, as the IRS prefers compliance over pursuing criminal action, even if you can't pay immediately; file to claim refunds (within 3 years) and avoid bigger penalties, and then contact the IRS for payment options like installment agreements if needed.

This process can include sending you notices, assessing penalties and interest, and taking more severe collection actions such as wage garnishment, tax liens, or levies on your property.
Canada's 90% rule helps non-residents and recent immigrants claim full federal tax credits (like the Basic Personal Amount) if 90% or more of their net worldwide income for the relevant tax year is from Canadian sources; otherwise, credits are prorated (reduced) based on their Canadian residency period, ensuring fairness for those who weren't residents all year.

Unreported income
