Missed Deadlines & Missed Payments Speak to your tax accountant about your 2021 tax deadline calendar

Missing tax deadlines and payments comes at a cost including a possible financial penalty or an interest fee. If you think you may miss a tax deadline or can’t afford your tax payments, it is a good idea to work closely with your tax accountant so they can advise on the best course of action and help you mitigate penalties where possible. If you don’t have a tax accountant and simply have some hypothetical questions you’d like to ask a tax expert, we suggest using our ad-hoc tax consulting service for on-demand answers.
