Prepaying tax for corporation after reassessment
We filed our corporation's taxes earlier this year. Our corporation had paid more than enough tax in advance and got a refund from the CRA. However, later I noticed that 3 expenses were understated by a total of ~$700, which resulted in an additional tax liability of ~$100 (small business tax rate). I filed the amended tax return using online filing more than 2 weeks ago. CRA's website still shows "Reassessment received" as the status. I'd like to pay the additional tax as soon as possible to prevent any interest/ avoid any penalties, if at all. I just can't find any option to pay this kind of tax. Is there any hidden option or should I just go ahead and use one of the existing options (Payment on filing/ Interim Amount owing/ Balance due) ?
