No. Theres no problem with CRO. However, you would need to check Revenue anti avoidance rules. Revenue may relook at short term businesses i.e. less than 3 years for example.
If you had planned your exit properly, you should have paid yourself salary in last 3 years and you could have taken a tax free lump sum (i.e. termination payment) as a result of losing your job. You could then voluntray strike it off for a few hundred euro.
Another option would be to extract the funds via salary and pension and pay tax at an effective rate of 48%-55% depending on your circumstances and then voluntary strike if off. This is not effective.
If in surplus, pay off all liabilities, receive all debts and voluntary strike off the company. Tax at 25% will be payable. This is the best option.
If not in surplus, you have to liquidate the company and pay tax of 25% on the surplus (if any). The liquidation fees could be anything like 4k-5k, depending on risk and time.
Has the company made a loss in its final year? If so, is terminal loss relief available?
You can strike off your company anytime upto your ARD date plus 28 days and save yourself the costs assosicated with producing accounts. However, you still need to do some accounts for the CT1 but they can be on an excel spreadsheet for example.
NB: Once you stop trading, this is the new CT1 period date, so you have 12 months to get your CT1 in. There is a new 12 month period from here.
Hope this helps a bit.
