Dollar-cost averaging to avoid buying at a highThe first argument against frontloading your IRA contributions is that doing so brings a risk that you’ll invest your contributions for the year at a relatively high cost basis. In other words, there’s a danger that you might buy into your stocks, funds or other investments at a high price point for the year, which could decrease your investment profits (or even put them in the red in the event of a market downturn later in the year). This is an especially pressing concern when stock indexes like the S&P 500 are near all-time highs.

This can mitigate the risk of buying in at a high point.

You can make contributions for the previous year until tax day
You can make contributions for the previous year until tax dayOne important thing to remember about the tax deduction from traditional IRA contributions is that there’s no big rush to claim it. To get the maximum tax deduction from IRA contributions for a given year, you don’t need to make all of your contributions by December 31 — you have until tax day (i.e., until April of the following year) to make contributions.

To get the maximum tax deduction from IRA contributions for a given year, you don’t need to make all of your contributions by December 31 — you have until tax day (i.e., until April of the following year) to make contributions.With this in mind, making small contributions throughout the year (rather than frontloading the maximum contribution) may give you a bit of “wiggle room” to reduce your tax bill at the last minute, in the event that your tax liability unexpectedly increases during the year.
With this in mind, making small contributions throughout the year (rather than frontloading the maximum contribution) may give you a bit of “wiggle room” to reduce your tax bill at the last minute, in the event that your tax liability unexpectedly increases during the year.For example, suppose you buy a health insurance plan through your state marketplace, and your income is low enough to qualify for the Advance Premium Tax Credit (APTC), which lowers your premiums. If your income unexpectedly increases during the year, you may no longer qualify for the APTC, in which case you may need to pay some of it back at tax time.

If your income during the year increased enough that you can make a last-minute contribution to your IRA, and you haven’t hit the limit yet, then you’ll be doing yourself two favors by making a last-minute contribution — you’ll offset the unexpected tax bill, and you’ll also give your retirement savings an extra boost.

But you have to weigh those nuances against a basic investing principle: Generally speaking, the earlier you invest money, the more time it’ll have to grow, and the higher your returns will be.The S&P 500 index has had an average annual return of about 10% per year before inflation over the last century. In some years, it returns more than that, in other years, it returns less. It doesn’t necessarily maintain a steady growth rate throughout the year, but nonetheless, it and other stock indexes generally tend to rise in value fairly consistently over the long term.

Funding other retirement accountsThe tax deduction on traditional IRA contributions is subject to income limits if you or your spouse has access to an employer-sponsored retirement plan like a 401(k). But if you don’t, then your traditional IRA contributions will be deductible no matter how high your income is.

But it has one notable disadvantage compared to making traditional IRA contributions: Traditional IRA contributions generally reduce your tax bill, while the backdoor Roth maneuver generally increases it.

If you’re on a tight budget, you may not be in a position to throw that kind of money into a retirement account very early in the year anyway. You may need to prioritize paying bills or building up an emergency fund instead.
