If I live overseas, can I still contribute the allowed maximum to my traditional IRA and my Roth IRA?

[Critter]

Yes BUT only if you have taxable earned income on your return ... if you exclude all your foreign income using the form 2555 then you will have no taxable earned income left on your return.

Yes ... please read the rules:  

General Limit For 2018, the most that can be contributed to your traditional IRA generally is the smaller of the following amounts. • $5,500 ($6,500 if you are age 50 or older). • Your taxable compensation (defined earlier) for the year.

What Isn’t Compensation? 

Compensation doesn’t include any of the following items. • Earnings and profits from property, such as rental income, interest income, and dividend income. • Pension or annuity income. • Deferred compensation received (compensation payments postponed from a past year). • Income from a partnership for which you don’t provide services that are a material income-producing factor. • Conservation Reserve Program (CRP) payments reported on Schedule SE (Form 1040), line 1b. • Any amounts (other than combat pay) you exclude from income, such as foreign earned income and housing costs.
