No you cant. �3000 is the limit per tax year regardless of withdrawls. Good news is that the new tax year starts on 6th April when you can make another �3000 deposit for the next tax year.
Somebody please correct me if I'm wrong but I was under the impression that the maximum you could deposit in any one tax year was �3000, but if you withdrew �1000 in the same tax tax, and then deposited �1000 back in that same tax year to bring the total back to �3,000. that was still within the rules ??
