Deferred tax

Hi, Can I check I've understood deferred tax correctly. Suppose you bought an asset for $400,000 which you will depreciate over 5 years. Capital allowance is 100% in the first year. Tax rate is 20%. So you'll have a temporary difference in year 1 of $320,000 which will be reduced each year until it's $0 in year 5. So in year 1 you credit deferred tax and debit tax liability by $64,000. Then each year for 4 years you debit deferred tax and credit tax liability by $16,000. Like this: Year 1 Dr DT 64,000.00 Cr Tax 64,000.00 Year 2 Dr Tax 16,000.00 Cr DT 16,000.00 Year 3 Dr Tax 16,000.00 Cr DT 16,000.00 Year 4 Dr Tax 16,000.00 Cr DT 16,000.00 Year 5 Dr Tax 16,000.00 Cr DT 16,000.00 Have I got this correct?
