I've seen several related questions on this website, but nothing for my particular problem. Consider the following MWE:
\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{amsmath}
\usepackage [english]{babel}
\usepackage [autostyle, english = american]{csquotes}
\usepackage{enumitem}
\begin{document}
\begin{enumerate}[label=(\roman*)]
\setlength\itemindent{0in}
\item $i = 0.06$
\item \begin{tabular}[h]{|l|c|c|c|c|}
\hline
& \multicolumn{2}{c|}{First Year} & \multicolumn{2}{c|}{Renewal Years} \\
\hline
& Percent of & Per & Percent of & Per \\
& Premium & Policy & Premium & Policy \\
\hline
Taxes & 4\% & 0 & 4\% & 0 \\
\hline
\end{tabular}
\end{enumerate}
\end{document}

I need this to look something like (modified using Paint):

\vspace{some length} has not worked after \item, as this shifts the \item as well. I have also tried using vspace and enclosing the tabular environment with {}; it gives the same effect which I don't want.
